b686855a94 feat(lfx): add pre-warm functionality (#13682)
* feat(lfx): add `prewarm` command for snapshot/preload warm-up

Warm component imports, the graph execution machinery, and specific flows
before a Firecracker snapshot or Gunicorn --preload fork, so the first
build/run after restore skips the cold lazy-import cost.

- prewarm_core_imports(): import core component classes + run a model-free
  hermetic flow (fork-safe: no network, no threads)
- prewarm_flow(flow, run=...): warm a specific flow by building it, or fully
  executing it for max warmth (drops graph + gc.collect after a run)
- freeze_heap(): gc.freeze() for copy-on-write sharing across fork/snapshot
- CLI: lfx prewarm with --flow, --skip-run, --freeze, and the gated
  --unsafe-run-may-leak-connections (Firecracker only; not fork-safe)

* feat(lfx): extract shared fork-safety toolkit (lfx.fork)

Add lfx.fork with the benign-thread allowlist, ghost-thread / ghost-TCP
detectors, a best-effort fork-safety report, and a dispose-in-finally helper.

- prewarm_flow now reports fork-hostile state left by a run (ghost_threads /
  ghost_connections), and the CLI warns when a run leaves connections open
  (safe for Firecracker restore, unsafe before a Gunicorn/preload fork)
- refactor langflow's gunicorn pre_fork hook to use lfx.fork instead of its
  own duplicated benign-thread allowlist + detection (behavior preserved)

* feat(lfx): dispose pluggable services before fork in prewarm path

The fork-safe prewarm path (prewarm_core_imports / prewarm_flow) triggers
lazy service discovery + instantiation, but never disposed what it
instantiated. With only bundled (fork-safe no-op) services this was
latent, but once a real lfx.services plugin (a DB pool, external cache
socket, or telemetry thread) is registered, the Gunicorn --preload fork
would inherit its live fds — the exact hazard Langflow's preload avoids
via engine.dispose() / cache teardown() before its master fork.

Wire that disposal into lfx:

- ServiceManager.teardown(raise_on_error=False): new strict mode that
  attempts every teardown then re-raises the first failure. Default
  preserves existing best-effort behavior.
- preload.teardown_warm_services(): disposes the global service manager,
  fatal (PrewarmError) on failure so a half-disposed process is never
  captured into a fork.
- prewarm_core_imports / prewarm_flow gain teardown_services=True
  (opt-out). prewarm_flow skips teardown on run=True (Firecracker
  intentionally keeps live connections). Results expose services_torn_down.
- The prewarm command centralizes teardown to one pass after all warming
  (so the per-flow layer doesn't re-instantiate disposed services) and
  skips it on --unsafe-run.

The global manager self-heals after teardown (deps re-registers factories
on next access; plugin service_classes survive — only instances drop).

* fix(lfx): capture prewarm_flow teardown failure in error, don't raise

prewarm_flow promises that one bad flow never aborts a multi-flow warming
loop (load/build/run failures go into result.error rather than raising).
The service-teardown step ran after the try/finally and could raise
PrewarmError, breaking that contract — a direct caller looping over many
flows would be aborted mid-batch by a single plugin's teardown failure.

Funnel the teardown failure into result.error like the other failures, and
document the cross-loop teardown caveat (warming runs in throwaway asyncio
loops; a loop-bound plugin resource may fail cross-loop, surfacing as a
fail-safe PrewarmError rather than silent corruption).

* fix(lfx): deliver input_value to prewarm runs; close fork-safety test gaps

Address code-review findings on the prewarm foundation:

- preload: wrap input_value in InputValueRequest in _run_flow_once. astep only
  reads inputs via .model_dump(), so the raw dict was silently dropped and the
  --unsafe-run flow executed with empty input.
- preload: dedup the two async_start loops into _run_flow_once.
- server: restore the 'psutil not installed' debug breadcrumb lost when pre_fork
  moved to the shared lfx.fork helpers.
- cli: include failed-import count in the prewarm summary line.

Tests (close clean-path-only gaps, same class as the input_value miss):
- input_value now reaches the flow output (regression).
- find_ghost_connections detects a real open connection (not just the empty path).
- prewarm_flow(run=True) surfaces a dirty fork-safety report.
- CLI emits the fork-unsafe warning when a run leaves ghost state.
- cross-loop service teardown fails loudly as PrewarmError.
- idempotent prewarm does not re-import (stable module identity).
- tighten warm-vs-cold speedup floor 5x -> 10x; verbose + unsafe-run CLI coverage.
- autouse fixture isolates the global ServiceManager between tests.

* chore(lfx): trim reviewer-facing comments and dedup prewarm tests

Cleanup pass on the prewarm foundation, no behavior change:
- tighten multi-sentence 'why' comments/docstrings to one natural line in
  preload, fork, _prewarm_commands, and manager.teardown.
- drop the tautological BENIGN_THREAD_PREFIXES membership test (the behavioral
  ghost-thread tests already cover it).
- reuse the _write_hermetic_flow helper in test_prewarm_flow_build_only instead
  of inlining the flow construction.

* fix(lfx): always run build-only teardown in prewarm_flow, even after a build error

Address CodeRabbit review on PR #13682:
- preload: drop the 'result.error is None' guard so prewarm_flow(run=False)
  disposes services even when the build failed — a partial build can leave
  services live and the process fork-unsafe (the library API was exposed; the
  CLI already did a final centralized teardown). Teardown failures now append
  to any existing build error instead of overwriting it.
- tests: cover build-failure-still-tears-down and the combined-error message.
- cli test: drop the fragile fork-unsafe warning assertion (process-global
  state incl. harness threads makes it flaky under --timeout-method=thread);
  connection-cleanliness is asserted at the library level instead.

* test(lfx): make prewarm speedup test measure cold-start, fix CI flake

The perf test timed build+run only (imports happened before the timer), where the
warm benefit is just a few x and machine-dependent — it failed on CI py3.14 at 6x
vs the 10x floor. Move imports inside the timed region so the test measures the real
value: full cold-start (import + build + run) in a fresh interpreter. Import
elimination is worth hundreds of x (observed ~700x locally), so a 10x floor now has
an enormous, machine-independent margin.

* fix(lfx): disable tracing during the prewarm warm-up run

The hermetic warm-up run writes nothing to the DB (message store needs a
session_id, vertex-build logging a flow_id — the hermetic graph has neither),
but lfx and Langflow share one service manager, so in a Langflow process the
graph AND each component independently resolve the real tracer and would ship a
junk 'prewarm' trace to a configured provider (LangSmith/Langfuse/...) and open
a socket, breaking fork-safety.

Wrap the run in a _tracing_disabled() context manager that blanks TRACING_SERVICE
in the shared manager so every get_tracing_service() returns None (no-tracing
build path), restoring the prior state afterward via an object() sentinel that
distinguishes 'absent' from 'present-but-None'.

Tests: warm-up run never touches a registered tracer; _tracing_disabled restores
all three prior states (absent / real service / present-None).

* fix(lfx): make fork-safety connection check reliable; drop dead helpers

Address review on PR #13682:
- deps: declare psutil in lfx (was only transitive via docling/accelerate extras,
  so a lean 'lfx serve' --preload install silently skipped the TCP ghost-connection
  check). find_ghost_connections now logs a warning instead of silently returning []
  if psutil is ever missing.
- cli: emit the fork-unsafe warning even when an --unsafe-run flow errors mid-run.
  Teardown is skipped on that path, so dirty state left by a failed run must still
  be announced; the warning is no longer gated behind the success branch.
- fork: remove fork_safe_teardown and ForkSafetyReport.is_clean — no production
  callers (they belong to the follow-up gunicorn PR), plus their now-dead tests/imports.

* fix(lfx): await-free all-types lookup so flows load (un-awaited coroutine)

AllTypesDict.get_type_dict called the async get_all_types_dict without awaiting
it, so the sync all_types_dict property did {**coroutine} and raised
"'coroutine' object is not a mapping". This path is hit during graph build when a
vertex falls back to resolve its base_type, so any flow reaching it failed to load
(lfx run and lfx prewarm --flow alike).

Use the sync build_custom_components instead — it is exactly what get_all_types_dict
awaits internally (verified equivalent: identical categories/components/templates;
only build-time timestamps differ, even sync-vs-sync). The consumer path is sync,
so it must not be a coroutine.

Verified: 21/33 starter templates warm via --flow end-to-end; the rest fail only on
missing optional component SDKs (trustcall, langchain_chroma, ...), not parsing.

7896b9f7f1 feat(bundles): metapackage split (Phase A) — engine-only lfx, lfx-bundles long tail, 5 graduated partner packages (#13563)
* feat(extension): add manifest-less lfx.bundles discovery + precedence tier

Foundation for the bundle metapackage split (1.11). Adds a third
@official-slot discovery source: a distribution declaring the
[project.entry-points."lfx.bundles"] group ships a package whose immediate
subdirectories are each a manifest-less bundle, folder-walked and registered
at @official with no extension.json (the langchain-community model).

- new loader/_bundles_root.py::load_lfx_bundles_extensions, mirroring
  discover_inline_bundles but sourcing roots from the lfx.bundles entry-point
  group via find_spec and reusing _load_bundle_directory
- discovery precedence becomes installed > seed > lfx_bundles > dev > inline
  so a manifest-shipping lfx-<provider> always shadows the same-named
  provider in the metapackage (lets a provider graduate with no lockstep
  release), emitting the existing bundle-shadowed warning
- new bundle-discovery-malformed warning code, emitted on warnings (never
  flips ok / aborts startup) for unresolvable declarations and invalid
  provider folder names
- exported via loader/__init__ and the lfx.extension PEP-562 lazy surface

10 new tests in test_load_lfx_bundles.py; full extension unit suite (449)
passes; ruff + format clean; mypy clean on the new module.

* docs(bundles): changelog entry for the lfx.bundles discovery surface

The BUNDLE_API.md changelog gate diffs each PR's branch against main, so
the entry covering this PR's surface additions (lfx.bundles discovery,
the lfx_bundles precedence tier, bundle-discovery-malformed) must live
on this branch, not only further up the stack. Text is verbatim from the
graduate-partners commit so the stacked merge dedupes trivially.

* fix(extension): reject plain-module lfx.bundles targets; correct validate wording

CodeRabbit review fixes on #13563:
- _spec_package_dir no longer falls back to a plain module's parent
  directory -- a single-file entry-point target now emits the
  bundle-discovery-malformed warning instead of folder-walking unrelated
  sibling directories as bundles (+ regression test)
- BUNDLE_API.md / loader docstring no longer say manifest-less providers
  are 'exempt from lfx extension validate'; they are not valid validator
  input (validate requires a manifest and reports manifest-not-found)

* fix(extension): review fixes — shadowed metapackage providers never import; typed manifest-less reload refusal

Review findings on #13563:

- A manifest-less provider whose bundle name is already claimed by a
  higher-precedence @official source (installed/seed) is now skipped
  WITHOUT importing: all @official sources share the
  _lfx_ext.official.<bundle>.* sys.modules namespace, so importing the
  losing copy overwrote the winner's live modules even though
  _resolve_bundle_shadowing dropped its components afterwards.  The
  orchestrator passes the claimed-name map (built by the new
  _claimed_official_bundles helper, mirroring the resolver's winner
  rule); the skipped copy still emits the typed bundle-shadowed warning.
  This collision is the expected post-graduation state, not an error.

- Manifest-less records now carry a manifestless provenance flag
  (additive field on LoadResult + BundleRecord).  The reload pipeline
  refuses them with the new typed reload-manifestless-unsupported code
  instead of routing through load_extension and failing with a
  misleading manifest-not-found.  Hot reload of metapackage providers
  is a process-restart concern (pip-installed content); a loader-based
  reload path can follow if QA wants it.

BUNDLE_API.md changelog entry extended for both surface changes.

* fix(extension): harden lfx.bundles discovery per review — broad find_spec guard, namespace portions, per-mode error codes

Review findings from ogabrielluiz on #13563:

- find_spec on a dotted declaration imports the PARENT package, whose
  __init__ can raise anything; a non-Import error escaped the old catch
  tuple and (through the palette cache's catch-all) wiped every source's
  components for the boot.  Catch Exception and degrade to the malformed
  sentinel; comment corrected.

- Namespace packages: walk ALL submodule_search_locations portions (one
  root per portion) instead of only locations[0], and dedupe resolved
  roots by path so duplicate entry-point declarations (or overlapping
  portions) never walk a directory twice and self-shadow.
  _spec_package_dir -> _spec_package_dirs.

- Split bundle-discovery-malformed into one code per failure mode,
  mirroring the inline tier: bundles-provider-name-invalid (rename the
  directory), bundles-root-unreadable (check permissions), keeping
  bundle-discovery-malformed for unresolvable declarations (fix the
  entry-point).  Same-tier duplicates get duplicate-lfx-bundles-provider
  instead of overloading bundle-shadowed, whose rendered template
  (format_extension_error renders templates, not ad-hoc messages) was
  wrong on both counts for that case.

- The claimed-bundles cross-source skip now emits bundle-shadowed on
  errors (matching _resolve_bundle_shadowing) so filtering by code never
  mixes severities; bundle-shadowed is already in the CLI warn-only set.

3 new regression tests (raising parent package, namespace portions,
duplicate entry points); BUNDLE_API changelog updated.

* feat(bundles): create lfx-bundles metapackage skeleton (#13564)

* feat(bundles): add lfx-bundles metapackage skeleton

Creates the manifest-less lfx-bundles distribution (the langchain-community
model) that the long-tail providers will move into. Empty skeleton for now;
the bulk move (scripts/migrate/consolidate_bundles.py) populates the provider
folders + per-provider extras later.

- src/bundles/lfx-bundles: a single pyproject declaring the lfx.bundles
  entry-point (lfx_bundles = "lfx_bundles"), an lfx>=1.10.0,<2.0.0 pin, and a
  generated (currently empty) `all` extra; plus a bare lfx_bundles namespace
  package and a README documenting the model + install stories
- wired into the root workspace via the existing bundle marker blocks:
  dep lfx-bundles[all]>=1.0,<2.0, uv source, and member
- hyphen dir name so release.yml's src/bundles/*/pyproject.toml glob builds
  it with zero workflow change

Verified: the wheel builds (entry_points.txt carries the lfx.bundles group);
load_lfx_bundles_extensions (PR-1) discovers the entry point and the empty
skeleton registers zero providers with no error.

* fix(ci): nightly bundle rename follows [extras] refs and self-refs

Two gaps in update_bundle_versions.py around extras suffixes, both fatal
or silently wrong for the first nightly carrying the lfx-bundles
metapackage:

- update_root_pyproject_for_bundle's dep regex required the version
  specifier immediately after the name, so "lfx-bundles[all]>=1.0,<2.0"
  (a MAIN dep) was left unrewritten while the workspace member was
  renamed to lfx-bundles-nightly; uv lock then tries to resolve stable
  lfx-bundles from PyPI, where it does not exist. The same gap silently
  left "lfx-docling[local]>=0.1.0" optional-dep refs pointing at the
  stable distribution. The regex now tolerates an [extras] group and
  carries it into the replacement.

- rename_bundle_pyproject skipped self-referencing extras, so the
  metapackage's generated `all` extra kept 45 "lfx-bundles[<provider>]"
  members after the rename, pulling the stable distribution (same
  lfx_bundles import package, install collision) once published. Self
  refs now follow the rename, idempotently.

Tests drive the real script module, mirroring test_bundle_lfx_pin.py.
This closes the PR-2 audit item flagged when the metapackage was
introduced. The canonical-pre-release cutover would retire the nightly
rename entirely; until it lands, the rename must be correct.

* fix(bundles): address review — drop orphaned nightly bundle-rename script, fix README install stories

- Delete scripts/ci/update_bundle_versions.py and its tests: the nightly
  bundle-rename track it served was retired by the canonical pre-release
  cutover (src/bundles/NIGHTLY.md) and no workflow or Makefile target on
  main or any release branch invokes it. Stale doc references in
  sync_bundle_lfx_pin.py and test_bundle_lfx_pin.py updated to match.
- README: split the install section into what works today (langflow, bare
  lfx) vs what arrives with the bulk move / engine-only split
  (lfx[bundles], per-provider lfx-bundles[<provider>] extras), and note
  the generated all extra is empty until the first provider tranche lands.

* ci(bundles): cross-bundle test matrix (lfx contract axis) (#13566)

* ci(bundles): add cross-bundle test matrix (lfx contract axis)

Tests every extracted bundle (the lfx-bundles metapackage + each graduated
lfx-<provider>) against the lfx contract surface it depends on -- overdue
since 1.10 left 4 independently-versioned bundles depending on lfx.

- .github/workflows/cross-bundle-test.yml: discovers bundles via the same
  src/bundles/*/pyproject.toml glob release.yml uses, then per
  (bundle x python 3.10/3.13): installs the in-repo lfx + the bundle, imports
  the declared entry-point package, asserts lfx.bundles discovery is
  error-free (for the metapackage), runs `lfx extension validate` for
  manifest bundles, and runs the bundle's own tests/.
- Triggers: pull_request (src/bundles, src/lfx), workflow_dispatch, a weekly
  schedule, and workflow_call.

The lfx-minor axis seeds with the in-repo lfx (the 1.10 line is unpublished);
when minors publish, add the version dimension (oldest+latest get full tests,
every supported minor gets contract-smoke) per the epic's cost-control shape.

Verified: the workflow YAML parses and the contract-smoke logic imports a
real bundle (lfx_arxiv) cleanly.

* fix(ci): cross-bundle smoke tolerates extras-less SDK degradation

Review findings on the cross-bundle matrix:

- CRITICAL: the contract smoke asserted zero discovery errors, but the CI
  venv installs lfx-bundles WITHOUT per-provider extras, so providers whose
  modules import their SDK at top level degrade with module-import-failed --
  the expected graceful-degradation contract. The smoke now fails only on
  structural codes and reports the degraded-module count. (Graduated partner
  bundles carry their deps directly, not as extras, so their steps are
  unaffected.)
- the scheduled run now actually delivers the exhaustive grid the header
  promised (all supported Pythons on schedule; oldest+latest on PRs)
- concurrency group with cancel-in-progress on PRs so stacked bundle PRs
  don't queue N-bundles x N-pythons jobs per push

* ci(bundles): tomli fallback for the py3.10 cross-bundle smoke

tomllib is stdlib only from Python 3.11, so the contract-smoke heredoc
failed with ModuleNotFoundError on every py3.10 matrix leg. Install the
tomli backport into the smoke venv and import it as a fallback.

* fix(test): coherent sys.modules restore in the ibm without_ibm_db fixture

The cross-bundle matrix's py3.10 leg exposed test-ordering pollution in
the ibm bundle suite: without_ibm_db monkeypatch-deleted three lfx_ibm
modules and re-imported them mid-test, but entries created during the
test survive teardown (delitem with raising=False records nothing for
keys it didn't find) and re-imported parents never regain the submodule
attribute bindings that mock.patch target resolution walks on Python
3.10 (3.11+ mock resolves via sys.modules and tolerates the
incoherence). Two fixture uses in sequence left the tree inconsistent
and 29 later watsonx tests failed with AttributeError on the package.

Snapshot, drop, and restore the entire lfx_ibm module tree wholesale
instead. Full suite now passes on both 3.10 and 3.13.

* feat(lfx): add lfx[bundles] extra and keep lfx engine-only (#13565)

* feat(bundles): add lfx-bundles metapackage skeleton

Creates the manifest-less lfx-bundles distribution (the langchain-community
model) that the long-tail providers will move into. Empty skeleton for now;

Verified: the wheel builds (entry_points.txt carries the lfx.bundles group);
load_lfx_bundles_extensions (PR-1) discovers the entry point and the empty
skeleton registers zero providers with no error.

* feat(lfx): add lfx[bundles] extra and keep lfx engine-only

lfx ships no bundles by default. The new optional extra pulls the long-tail
metapackage for users who want the provider components without the full
langflow server install.

- src/lfx/pyproject.toml: [project.optional-dependencies]
  bundles = ["lfx-bundles[all]>=1.0,<2.0"]; intentionally NO lfx[all]
- pip install lfx          -> engine only
  pip install "lfx[bundles]" -> engine + the lfx-bundles long tail
  (documented as a headless/serverless deployment footnote, not a headline)

Verified against the built lfx wheel METADATA: lfx-bundles appears only under
`extra == "bundles"`, never in core Requires-Dist, so the engine-only default
is preserved.

* fix(ci): nightly bundle rename follows [extras] refs and self-refs

Two gaps in update_bundle_versions.py around extras suffixes, both fatal
or silently wrong for the first nightly carrying the lfx-bundles
metapackage:

- update_root_pyproject_for_bundle's dep regex required the version
  specifier immediately after the name, so "lfx-bundles[all]>=1.0,<2.0"

* ci(bundles): freeze lfx/components against new top-level providers (#13567)

model) that the long-tail providers will move into. Empty skeleton for now;

folders + per-provider extras later.

skeleton registers zero providers with no error.

* ci(bundles): freeze lfx/components against new top-level providers

After the metapackage split, new providers go to lfx-bundles (or a graduated
lfx-<provider>), never in-tree. Adds an additions-only CI gate.

- scripts/ci/check_components_frozen.py: stdlib gate comparing the live
  top-level dir listing of src/lfx/src/lfx/components/ against a committed
  baseline; fails on any directory not in the baseline. Removals are allowed
  so M4 shim cleanup (which shrinks the set) never trips it.
- scripts/ci/frozen_component_dirs.txt: the 111-dir baseline.
- .github/workflows/lint-py.yml: new freeze-components job runs the gate
  (stdlib-only, no uv sync).

Verified locally: passes on the baseline, fails (exit 1) on a simulated new
provider directory with an actionable message, passes again after cleanup.

* fix(ci): freeze gate counts only dirs shipping __init__.py

Review finding: a stray directory holding only __pycache__ bytecode (left
behind by a branch switch) tripped the additions-only gate locally. A
directory without __init__.py is not a provider; ignore it.

* fix(ci): nightly bundle rename follows [extras] refs and self-refs

Two gaps in update_bundle_versions.py around extras suffixes, both fatal
or silently wrong for the first nightly carrying the lfx-bundles
metapackage:

- update_root_pyproject_for_bundle's dep regex required the version
  specifier immediately after the name, so "lfx-bundles[all]>=1.0,<2.0"
  (a MAIN dep) was left unrewritten while the workspace member was
  renamed to lfx-bundles-nightly; uv lock then tries to resolve stable
  lfx-bundles from PyPI, where it does not exist. The same gap silently
  left "lfx-docling[local]>=0.1.0" optional-dep refs pointing at the
  stable distribution. The regex now tolerates an [extras] group and
  carries it into the replacement.

- rename_bundle_pyproject skipped self-referencing extras, so the
  metapackage's generated `all` extra kept 45 "lfx-bundles[<provider>]"
  members after the rename, pulling the stable distribution (same
  lfx_bundles import package, install collision) once published. Self
  refs now follow the rename, idempotently.

Tests drive the real script module, mirroring test_bundle_lfx_pin.py.
This closes the PR-2 audit item flagged when the metapackage was
introduced. The canonical-pre-release cutover would retire the nightly
rename entirely; until it lands, the rename must be correct.

* feat(bundles): move 45 long-tail providers into lfx-bundles + graduate 5 partner packages (#13568)

* feat(bundles): add lfx-bundles metapackage skeleton

Creates the manifest-less lfx-bundles distribution (the langchain-community
model) that the long-tail providers will move into. Empty skeleton for now;
the bulk move (scripts/migrate/consolidate_bundles.py) populates the provider
folders + per-provider extras later.

- src/bundles/lfx-bundles: a single pyproject declaring the lfx.bundles
  entry-point (lfx_bundles = "lfx_bundles"), an lfx>=1.10.0,<2.0.0 pin, and a
  generated (currently empty) `all` extra; plus a bare lfx_bundles namespace
  package and a README documenting the model + install stories
- wired into the root workspace via the existing bundle marker blocks:
  dep lfx-bundles[all]>=1.0,<2.0, uv source, and member
- hyphen dir name so release.yml's src/bundles/*/pyproject.toml glob builds
  it with zero workflow change

Verified: the wheel builds (entry_points.txt carries the lfx.bundles group);
load_lfx_bundles_extensions (PR-1) discovers the entry point and the empty
skeleton registers zero providers with no error.

* feat(bundles): consolidate first long-tail tranche into lfx-bundles

Adds scripts/migrate/consolidate_bundles.py (the inverse of port_bundle.py --
moves in-tree providers into the manifest-less lfx-bundles metapackage) and
runs it on a verified 5-provider tranche: tavily, exa, wikipedia, yahoosearch,
wolframalpha.

Per provider the script:
- moves src/lfx/src/lfx/components/<p>/ -> lfx_bundles/<p>/ (lowercase names);
- leaves a fail-soft import shim (first line `# lfx-bundles-shim`) so
  `from lfx.components.<p> import X` keeps working when lfx-bundles is
  installed, and raises an actionable ImportError otherwise;
- merges the provider's third-party deps into a PEP 685-normalized lfx-bundles
  extra and regenerates the `all` aggregate. Dep parity holds: `uv sync` is a
  no-op because those deps were already pulled via langflow-base[complete];
- appends the 4-entry migration block per Component class (28 entries) so saved
  flows referencing lfx.components.<p>.<Class> migrate to
  ext:<p>:<Class>@official.

To avoid double registration, the in-tree component walk
(_load_components_dynamically) now skips shimmed provider dirs, and
component_index.json is regenerated (355->348 components, 95->90 modules); the
moved providers load only at @official via lfx.bundles discovery.

Verified: discovery finds all 5 at @official with no errors; shims resolve;
`import lfx.components` still works; the index drops the 7 moved component
entries (residual `tools`-category name refs resolve via the shim); ruff clean.

First tranche proves the engine; the remaining long-tail scales by extending
PROVIDER_DEPS (each provider's deps verified individually -- the careful part).

* feat(bundles): consolidate 30-provider tranche 2 into lfx-bundles

Extends PROVIDER_DEPS with 30 individually-verified providers and runs the
consolidation: vector stores (chroma, clickhouse, couchbase, milvus, mongodb,
pgvector, pinecone, qdrant, supabase, upstash, weaviate), model providers
(groq, mistral, ollama, perplexity, sambanova), and tools/memory/data (apify,
assemblyai, confluence, firecrawl, git, glean, icosacomputing, mem0, needle,
scrapegraph, serpapi, unstructured, youtube, zep).

Dep verification (the careful part): every spec comes from langflow-base's
per-provider extras or its direct dependencies; langchain-community providers
carry the wrapper plus the SDK the wrapper lazy-imports (e.g. pgvector,
atlassian-python-api); requests is declared explicitly where imported (it is
only transitive in today's env); pinecone keeps its python_version<'3.14'
marker verbatim. Tranche excludes: providers with langflow imports (vlmrun),
provider-specific lfx.base dirs (composio/huggingface/langwatch), case-
sensitive names (FAISS/Notion), the openai-SDK family (azure/aiml/deepseek/
litellm/lmstudio/novita/openrouter/vllm/xai/cometapi -- cleaner after PR-8),
and the partner set.

Dep parity verified at the resolution level: the uv.lock diff is +220 lines of
lfx-bundles extras metadata with ZERO packages added or removed (`name =` diff
empty), so pip install langflow resolves the identical set.

Also: 192 append-only migration entries (48 classes x 4, zero bare-name
ambiguities); component_index.json regenerated 348->300 components / 90->60
modules (exactly the moved set, no stale standalone entries); mongodb_atlas.py
SLF001 per-file-ignore and the mem0/mongodb detect-secrets baseline entries
migrated to the new paths (lint/secrets exceptions travel with moved files);
35 bundles now discover at @official with 55 components; shims verified across
categories; 449 extension tests pass.

* feat(bundles): consolidate openai-SDK family tranche 3 into lfx-bundles

10 providers that ride the langchain-openai wrapper, deferred from tranche 2
until the partner graduation settled the openai-SDK dep story: aiml, azure,
cometapi, deepseek, litellm, lmstudio, novita, openrouter, vllm, xai.

Dep verification: every provider declares langchain-openai>=1.1.6; the openai
SDK is declared only where a component imports it directly (aiml, deepseek,
litellm, lmstudio, vllm, xai -- wrapper-transitive elsewhere); requests
declared where imported (cometapi, deepseek, novita, xai); lmstudio's lazy
NVIDIAEmbeddings path gets langchain-nvidia-ai-endpoints~=1.0.0. The litellm
component drives LiteLLM-served endpoints through the OpenAI client and does
NOT import the litellm package -- langflow-base's litellm extra stays put.
These providers use the lazy _dynamic_imports __init__ shape; it survives the
move unchanged (import_mod resolves via __spec__.parent and
lfx.components._importing remains a core helper).

Dep parity: uv.lock diff has zero package additions/removals (all specs
already resolved via langflow-base[complete]).

Also: 56 append-only migration entries (14 classes x 4, zero ambiguities);
component_index.json regenerated 300->286 components / 60->50 modules (exactly
the moved set); detect-secrets baseline re-keyed; 45 bundles now discover at
@official with 69 components; shims verified (azure/xai/litellm/deepseek);
ruff clean.

* fix(ci): nightly bundle rename follows [extras] refs and self-refs

Two gaps in update_bundle_versions.py around extras suffixes, both fatal
or silently wrong for the first nightly carrying the lfx-bundles
metapackage:

- update_root_pyproject_for_bundle's dep regex required the version
  specifier immediately after the name, so "lfx-bundles[all]>=1.0,<2.0"
  (a MAIN dep) was left unrewritten while the workspace member was
  renamed to lfx-bundles-nightly; uv lock then tries to resolve stable
  lfx-bundles from PyPI, where it does not exist. The same gap silently
  left "lfx-docling[local]>=0.1.0" optional-dep refs pointing at the
  stable distribution. The regex now tolerates an [extras] group and
  carries it into the replacement.

- rename_bundle_pyproject skipped self-referencing extras, so the
  metapackage's generated `all` extra kept 45 "lfx-bundles[<provider>]"
  members after the rename, pulling the stable distribution (same
  lfx_bundles import package, install collision) once published. Self
  refs now follow the rename, idempotently.

Tests drive the real script module, mirroring test_bundle_lfx_pin.py.
This closes the PR-2 audit item flagged when the metapackage was

rename entirely; until it lands, the rename must be correct.

* feat(bundles): graduate partner set to standalone lfx-<provider> packages (#13573)

* feat(bundles): graduate partner set to standalone lfx-<provider> packages

Extracts the five partner/flagship providers into manifest-shipping
distributions: lfx-openai, lfx-anthropic, lfx-amazon, lfx-datastax,
lfx-cohere. Each ships extension.json (lfx.compat ["1"]), a
langflow.extensions entry-point, an lfx>=1.10.0,<2.0.0 pin, and is wired into
the root workspace marker blocks. Zero flow impact by the bundle-name
invariant: ext:<provider>:<Class>@official ids are unchanged.

Mechanics:
- adopts the five-phase scripts/migrate/port_bundle.py from
  feat/bundle-mass-extraction (handles shared-base moves, consumer rewrites,
  surgical index updates, migration-table appends) and runs it per partner
  with --migration-release 1.11.0
- datastax's shared lfx.base.datastax moves into lfx_datastax.base; its
  backend unit tests move to src/bundles/datastax/tests (74 pass); its ruff
  per-file-ignore and its check_component_env_writes ALLOWLIST entry travel;
  10 repo consumers rewritten (incl. the vector_store_rag starter project)
- amazon_bedrock_converse.py legacy langflow.* imports rewritten to the lfx.*
  equivalents (thin re-export aliases; behavior-identical) pre-extraction
- runtime deps pinned from langflow-base's extras / direct deps (wrapper-
  guaranteed SDKs stay transitive, parity-exact); --remove-base-extra dropped
  the openai/anthropic/cohere/aws extras from langflow-base[complete] in favor
  of the bundle pins; the astradb extra stays (also used outside datastax)
- in-tree dirs replaced with marker shims pointing at lfx_<p>.components.<p>
  (skipped by the in-tree walk; legacy from lfx.components.<p> imports keep
  working); lfx/components/__init__.py entries kept, consistent with the
  consolidated providers
- validate.py: accept classes whose base is a *derived* Component base
  (LCVectorStoreComponent / LCToolComponent / ...) -- they inherit the
  class-level outputs declaration and only override the output method, which
  the AST-only check could not see; bare Component subclasses keep the strict
  build/outputs requirement (+ regression test)
- BUNDLE_API.md changelog entries added for the branch's surface changes: the
  lfx.bundles manifest-less discovery group + precedence tier +
  bundle-discovery-malformed code (from the foundation PR) and the validator
  acceptance above
- 100 append-only migration entries (20 classes x 5 partners x 4 shapes);
  component_index.json surgically updated 300->280 components / 60->55
  modules, sha256 recomputed and verified
- detect-secrets baseline re-keyed for moved partner files

Dep parity: lock diff adds only the five lfx-* package names; no third-party
package added or removed. One benign transitive re-resolution: anthropic SDK
0.105.2 -> 0.109.0 (allowed by langchain-anthropic's range on both sides).

Verified: all five register at @official via the installed-manifest tier
(extension_id/distribution = lfx-<p>, 20 components); manifest-less
lfx_bundles unchanged (35 bundles, disjoint); all 5 shims import; engine-safe;
`lfx extension validate` passes for all five; 450 extension unit tests, 60
pilot-upgrade migration tests, 74 moved datastax tests pass; ruff clean.

* fix(bundles): shim lfx.base.datastax so stored-flow imports keep resolving

The datastax graduation moved lfx.base.datastax into lfx_datastax.base,
but saved flows and starter templates (Hybrid Search RAG,
TemplateAssistant) embed `from lfx.base.datastax.astradb_base import
AstraDBBaseComponent` inside their stored component code fields, which
is re-executed verbatim at flow build time. Without a shim that import
raises ModuleNotFoundError and the flows fail to build
(test-starter-projects red).

Mirror the lfx.components shim contract: module-aliasing to
lfx_datastax.base, narrow except that only translates a missing bundle
(transitive dep failures re-raise untouched), marker-tagged single-file
dir, removed at M4 together with the components shims.

* chore(bundles): bounded version ranges for curated lfx-* packages (#13576)

langflow's pyproject is the release-coordination point now that lfx and the
lfx-* bundles release independently. Every curated lfx-* dependency declares a
BOUNDED range (>=A,<B), never an exact pin -- exact pins in reusable library
metadata create resolver conflicts for downstreams that depend on a different
version. Exact pins for reproducibility live in uv.lock and the release-build
manifests.

- the 4 pilots + 5 graduated partners: >=0.1.0 -> >=0.1.0,<1.0.0 (bundles
  follow their own 0.1.x cadence)
- lfx-bundles[all]>=1.0,<2.0 unchanged (versions with the metapackage
  contract)
- the three lfx-docling[...] optional-dependency refs bounded the same way
- policy documented inline in the bundle-deps marker block; the cross-bundle
  CI matrix verifies the ranges resolve together across the supported lfx axis

Verified: uv lock resolves with zero package/version changes (bounds are
metadata-only today); the nightly rename's dep regex already matches the
bounded form.

* test(bundles): lock the in-tree shim contract + breakage audit

Locks the five-point contract for the 50 lfx-bundles import shims under
lfx/components/ (45 metapackage + 5 graduated partners):

  1. first line is the `# lfx-bundles-shim` marker (keys the in-tree walk's
     double-registration skip);
  2. a shim dir is exactly one __init__.py -- no impls, no deps;
  3. sys.modules module-aliasing (submodule trees resolve);
  4. bundle missing -> actionable ModuleNotFoundError whose wording is part
     of the contract ("pip install lfx-bundles" / "pip install lfx-<p>");
  5. a missing *transitive* dep re-raises untouched.

Test shape (env-adaptive by design -- the lfx test env prunes the venv, so
nothing here assumes bundles are installed):
- source-level sweep of every real shim, parameterized (no imports);
- hermetic mechanism tests against a synthetic shim + synthetic target
  (alias-resolves / locked-message / transitive-reraise);
- the walk-skip detector and the marker sweep must agree exactly;
- one adaptive live test on lfx.components.tavily exercising whichever
  branch the running env is in.

106 tests pass in the pruned lfx env (where the live test exercises the
bare-engine locked-message branch).

Breakage audit (gh code search, recorded in the PR): ~20-25 public repos
reference lfx.components.*; the majority are langflow forks (vendored tree,
unaffected by packaging). Genuine library consumers exist and the moved
providers have real surface (openai: 11 external repos, datastax: 17) --
covered by the shims wherever bundles are co-installed (every
`pip install langflow`). Decision: deprecation warnings NOT warranted now;
revisit at M4 (shim removal), where one loud minor release before removal
is the right shape.

* test(bundles): extend the shim contract sweep to lfx.base shims

The datastax graduation moved lfx.base.datastax into lfx_datastax.base
and left a module-aliasing shim behind (stored flow code fields embed
the legacy import and are re-executed verbatim at build time). Sweep
lfx/base for marker shims with the same source-level contract as the
components sweep: one-file stub, module-aliasing to the bundle's base
subpackage, narrow name-checked except, locked install message.

* docs(bundles): install shapes, override rule, bundle_api_version (#13578)

Documents the deliberately small user-facing rule surface of the metapackage
split (1.11):

- extensions-overview.mdx: the two install stories (pip install langflow =
  everything, same as today; pip install lfx = engine only, bring your own
  bundles); the bundle-name-is-identity invariant; the current package table
  (lfx-bundles metapackage + the 5 partner packages + the 4 pilots); the
  legacy-import shim behavior with the locked ModuleNotFoundError wording and
  the migration recipe for direct lfx users (switch to lfx[bundles] or pin
  lfx-<provider> packages); the override rule ("ship a manifest -- a manifest
  always wins", with the bundle-shadowed warning); bundle_api_version as the
  single compat number (lfx.compat ["1"]; manifest-less packages ride their
  PEP 508 lfx pin) and the no-version-arithmetic rule.
- deployment-lfx-compatibility.mdx: lfx[bundles] as the headless/serverless
  deployment footnote (engine + lfx-bundles[all]; slimmer per-provider
  alternative; intentionally no lfx[all]).

Both files verified MDX-safe (no unbackticked angle brackets).

Both files verified MDX-safe (no unbackticked angle brackets).

* fix(bundles): review fixes — symlink containment, idempotency, docs accuracy

Fixes from the multi-agent stack review (kept as a separate PR so the
reviewed PRs' diffs stay frozen for QA's independent pass):

- _bundles_root.py: directory-level symlink containment — a provider dir
  that resolves outside the bundle root is skipped with a typed
  bundle-discovery-malformed warning, mirroring the seed-directory walk's
  is_within rule (+ regression test). Anchors the trust boundary to the
  installed package tree.
- consolidate_bundles.py: migration-append idempotency guard — entries are
  deduped on full content so a partially-failed earlier run cannot duplicate
  rows on re-run (table stays append-only).
- langflow-base pyproject: documented WHY the aws extra is deliberately
  retained after the lfx-amazon graduation (boto3 also backs the server's
  own S3 storage backend and lfx's S3 ingestion — review suggested removing
  it; that would regress S3 storage support).
- extensions-overview.mdx: note that `lfx extension list` shows
  manifest-shipping extensions only; manifest-less packages load at startup
  but are not listed.

93 loader+migration tests pass (incl. the new symlink test); ruff clean.

* refactor(bundles): stabilize import_mod as a public BUNDLE_API utility

The lazy-import helper that bundle packages call from their
__getattr__-based __init__.py files lived at lfx.components._importing -- an
internal path with no stability contract, imported by 35 separately-installed
bundle __init__ files (30 lfx-bundles providers + the 5 graduated partners).

- canonical home is now lfx.utils.lazy_import.import_mod (code unchanged);
  lfx.components._importing re-exports it so in-tree callers and any external
  code on the old path keep working
- all 35 bundle-side imports rewritten to the stable path
- BUNDLE_API.md: surface table entry + changelog (additive)
- contract tests: re-export identity, both call forms, the AttributeError
  conversion

Verified: identity holds across both paths; lazy __init__ loads work through
the new path for both bundle families; 110 tests pass; ruff clean.

* fix(bundles): tombstone the broken legacy ZepChatMemory build method (#13580)

build_message_history targeted the zep-python v1 SDK (ZepClient +
zep_python.langchain.ZepChatMessageHistory); both were removed in
zep-python 2.x and the zep extra pins 2.0.2, so the method has been
unable to run for as long as the pin has existed -- its ImportError
guard misleadingly told users to 'pip install zep-python' (already
installed). The component is legacy=True with helpers.Memory as its
designated replacement, so rather than hand-write a new integration
against the 2.x SDK, the method now raises a clear RuntimeError
pointing at the Message History component.

Flow identity is preserved: class/component name, display_name,
description, inputs and the memory output are byte-identical, so saved
flows keep loading, i18n locale keys are unchanged, and
migration_table.json needs no edits. New bundle tests pin the stub
contract (identity, actionable error, no zep_python import).

* test(bundles): extend the shim contract sweep to lfx.base shims

The datastax graduation moved lfx.base.datastax into lfx_datastax.base
and left a module-aliasing shim behind (stored flow code fields embed
the legacy import and are re-executed verbatim at build time). Sweep
lfx/base for marker shims with the same source-level contract as the
components sweep: one-file stub, module-aliasing to the bundle's base
subpackage, narrow name-checked except, locked install message.

* test(bundles): extras-drift guard for the lfx-bundles metapackage

Risk-2 of the metapackage split: the generated `all` extra and the
per-provider extras must never drift by hand-edit, or `pip install
langflow` silently loses a provider's deps. Guard the four invariants:
extras <-> provider dirs (PEP 685-normalized), `all` == the exact
self-ref set, normalized keys collision-free, and the metapackage
provider set disjoint from the graduated partner distributions.

* fix(extension): symlink-escaped providers reject with path-escape, matching the documented contract

The lfx.bundles provider containment check (stack-review symlink fix)
emitted bundle-discovery-malformed, whose template and hint describe a
broken entry-point declaration.  The changelog's path-safety entry
already documents symlink escapes as path-escape on every other
discovery path; use the same code here.  Also resolves the semantic
merge conflict with the per-mode code split (the removed
_malformed_error location kwarg).

* fix(tests): repoint lfx tests off moved providers; complete provider fallback map

CI fail-fast had been masking these: the LFX test job runs in an
engine-only env where openai/anthropic/chroma are now bundle-package
shims, so every test that used them as the example category failed on
all Python versions (3.14 just reported first), and the backend Group 2
leg failed collecting test_lfx_bundles_extras.py on Python 3.10.

- flow_requirements: complete _PROVIDER_PACKAGE_FALLBACKS for the nine
  moved model providers (OpenAI, Anthropic, Amazon Bedrock, Groq,
  Google Generative AI, SambaNova, IBM watsonx.ai, Ollama + existing
  Azure OpenAI). In engine-only installs MODEL_PROVIDERS_DICT registers
  only in-tree providers, so the dynamic source-inspection path cannot
  resolve moved providers; the static fallbacks keep lfx run/serve
  requirements inference working. A dict hit still wins.
- test_dynamic_imports / test_import_utils: use composio (still-in-tree
  lazy category with its SDK absent in the bare env) as the example
  category instead of openai/anthropic/chroma; patch import_module at
  its canonical home lfx.utils.lazy_import.
- flow-builder tests (build_flow_from_spec, flow_builder_tools,
  propose_field_edit): specs use LanguageModelComponent (in-tree)
  instead of OpenAIModel.
- test_lfx_bundles_extras: tomli fallback for Python 3.10 (tomllib is
  stdlib 3.11+; pytest guarantees tomli on <3.11).

Full lfx unit suite: 4550 passed. Backend extras+pin tests: 24 passed.

* fix(tests): repoint MCP client-server tests off graduated OpenAIModel key

Same fail-fast-masked class as 14dfa7f268, backend side: since the
partner graduation, extension components register in /api/v1/all under
their namespaced ids (ext:openai:OpenAIModelComponent@official), so the
bare 'OpenAIModel' key these tests hardcoded no longer exists on any
Python version (the 'py3.14-only' Group 2 failure was the only leg that
ran; 3.10 was cancelled by fail-fast). The MCP feature itself is fine —
search returns the namespaced ids and add_component accepts them.

- Use LanguageModelComponent (in-tree, stable bare key; SecretStr
  api_key, real_time_refresh fields, advanced 'stream', LanguageModel
  output) for the redaction/configure/search/describe/spec tests.
- configure_dynamic_field: model_name -> api_key (the refresh field on
  LanguageModelComponent).
- prompt-template-variables spec: drop the model node — server-side
  validation builds the graph and a model without an API key fails its
  build; the test's subject is the dynamic {var} fields.

Full file: 69 passed.

* fix: restore loading.py and tableAutoCellRender to base-branch state

Commit 9df9475615 ('Frontend test updates') accidentally reverted both
files to their pre-#9902 state, removing the no_env_fallback contract in
load_from_env_vars / update_table_params_with_load_from_db_fields, the
defensive params.pop('code') in build_custom_component, and the
localValue/updateGlobalVariableCell handling in tableAutoCellRender.
The base branch's regression tests (test_loading_no_env_fallback.py,
test_loading_custom_component_code_param.py, tableAutoCellRender
index.test.tsx) were kept, so the reversion failed them.

* ci(bundles): make freeze gate reachable on PRs; review follow-ups

- Move the freeze-components job from lint-py.yml (workflow_call/
  workflow_dispatch only -- never invoked, so the gate could not block a
  PR) into extension-migration-checks.yml, which already triggers on
  pull_request for src/lfx/src/lfx/components/**. Add the gate's script
  and baseline to the path filter.
- Add timeout-minutes to the cross-bundle-test jobs so a hung install or
  test leg cannot occupy a runner for the 360-minute default.
- _discover_shimmed_component_dirs: read only the first line of each
  __init__.py instead of the whole file -- the shim marker contract is
  line 1 (enforced by test_shim_source_contract), and this prevents a
  non-shim file with the marker after leading blank lines from being
  misclassified and silently skipped from the in-tree walk.

* fix(bundles): restore legacy-name resolution for ext components; sync starter projects

Saved flows reference moved providers by their legacy palette identity --
either the bare class name (TavilySearchComponent) or the component's
name attribute (AstraDB, Chroma, needle, OllamaModel). After the provider
move neither resolved to a current template on the backend:

- lfx.utils.component_aliases now derives the bare class name (and its
  Component-stripped form) from ext:<bundle>:<Class>@<slot> keys,
  mirroring the frontend's getTemplateAliases. Ext templates carry
  name=None / _type='Component', so the key is the only source.
- _decorate_template_with_extension now stamps template['name'] with the
  component's legacy identity (name attr, falling back to class name).
  In-tree palette entries expose it as the dict key; ext entries are
  keyed by namespaced id, so without this both alias maps lose the only
  bridge from node types like 'AstraDB' to the current template.

Without these, the starter-project updater could not match moved-provider
nodes, so their embedded code stayed one whitespace change behind the
bundle sources -- every such flow showed the update-all banner, and
because tool-mode nodes' saved outputs ([component_as_tool]) differ from
the template's natural outputs the update was flagged breaking, opening
the confirmation modal instead of toasting 'successfully updated':
deterministic timeouts in the starter-project Playwright specs (shards
29/30/36/37). Regenerated the 13 affected starter projects with
scripts/ci/update_starter_projects.py (idempotent; code_hash hex strings
in the regenerated JSONs are detect-secrets false positives).

Also converts test_groq_integration.py to the captured-module
patch.object pattern (same module-identity trap as test_mongodb_atlas:
dotted-name @patch can land on a different materialization of the moved
module than the one that defined the class, leaving the real
get_groq_models in the instance's globals -- order-dependent failure in
unit-test Group 5).

* fix(bundles): keep importable module paths in starter projects

The starter-project updater syncs node metadata from the live templates
(NODE_FORMAT_ATTRIBUTES includes 'metadata'), and ext components report
their runtime sys.modules namespace there (_lfx_ext.official.<p>.<m>) --
a path that only exists inside a running extension loader. Persisting it
broke test_template_field_order_matches_component in both template jobs
('No module named _lfx_ext'): the test imports metadata.module to
instantiate the component, and the migration table likewise keys on the
legacy lfx.components.<provider> form that the bundle shims keep
importable.

_merge_node_metadata now preserves the node's stored module when the
live template's is a runtime _lfx_ext.* path, while still syncing the
rest of the metadata (e.g. dependencies). Starter projects regenerated
from the pre-pollution state with the fixed updater: the only diff vs
the previous regen is the 20 module lines reverting to the legacy
importable form. Regression tests added for both merge directions.

* feat(lfx): fail-fast dependency preflight for `lfx run` (#13680)

Detect a flow's required third-party packages before the graph load and
fail fast with an actionable `pip install ...` message when any are
missing, instead of a deep ModuleNotFoundError mid-build. Addresses the
'export a flow, run it on a bare pip install lfx, it fails' confusion
introduced by the bundle split.

- flow_requirements: add find_missing_dependencies / _is_installed /
  format_missing_dependencies_error (best-effort, reuses the existing
  flow analyzer).
- run.base: _preflight_dependencies helper + check_dependencies gate in
  run_flow (JSON flows only; .py uses PEP 723; fail-open on analysis
  errors so a runnable flow is never blocked by the check itself).
- CLI: --check-dependencies/--no-check-dependencies on `lfx run`.
- tests: unit (find_missing_dependencies/format) + integration (run_flow
  + _preflight_dependencies).

* feat(bundles): move spider + toolguard provider components into lfx-bundles

Two provider components were still living inside otherwise-core directories
(file-level stragglers from the metapackage split). Both are portable
(lfx-only imports) and gated by dedicated optional SDKs, so they belong in
the lfx-bundles metapackage rather than lfx core:

- SpiderTool (langchain_utilities/spider.py) -> lfx_bundles/spider/, dep
  spider-client (`spider` extra).
- PoliciesComponent + policies/ submodule (models_and_agents) ->
  lfx_bundles/toolguard/, dep toolguard (`toolguard` extra).

Changes:
- Move the files into lfx_bundles/<name>/; rewrite policies' absolute
  self-imports (lfx.components.models_and_agents.policies -> lfx_bundles.toolguard.policies).
- Drop SpiderTool / PoliciesComponent from the core langchain_utilities /
  models_and_agents lazy-import registries.
- Add `spider` and `toolguard` extras to lfx-bundles pyproject + the generated
  `all` aggregate; uv.lock re-resolved (uv lock --check clean).
- Append migration entries (4 per class) mapping the historical
  lfx.components.* paths to ext🕷️SpiderTool@official /
  ext:toolguard:PoliciesComponent@official so saved flows migrate.
- Regenerate component_index.json (both classes drop out of core; 263
  components / 45 categories).
- Repoint the toolguard policies tests to lfx_bundles.toolguard (60 pass).

The toolguard deadlock-warmer (_warm_circular_imports) is unaffected: it warms
toolguard.runtime directly and runs single-threaded before the unified
component fan-out that loads bundle components.

* chore: auto-bake note keys and regenerate backend locales/en.json [skip ci]

* feat(bundles): consolidate cleanlab, twelvelabs, jigsawstack into lfx-bundles

First directory-level batch of the core-tail consolidation (validates the
consolidate_bundles.py path end-to-end after the spider/toolguard file-level
extractions). All three are flat, lfx-only, single-SDK providers:

- cleanlab    -> lfx_bundles/cleanlab    (cleanlab-tlm)   3 components
- twelvelabs  -> lfx_bundles/twelvelabs  (twelvelabs)     7 components
- jigsawstack -> lfx_bundles/jigsawstack (jigsawstack)   11 components

Via scripts/migrate/consolidate_bundles.py --apply: moves each dir into the
metapackage + leaves a fail-soft shim, merges per-provider extras and regen
`all`, appends the 4-entry migration block per class (84 entries, 0 ambiguous).
Component index regenerated (45->42 categories, 263->242 core components);
uv.lock re-resolved; twelvelabs test repointed to lfx_bundles.twelvelabs (passes).

* feat(bundles): consolidate vector/datastore + community-wrapper providers into lfx-bundles

Second directory-level batch (8 providers, 12 components) via
consolidate_bundles.py --apply:

- baidu (qianfan + langchain-community), redis (redis + community),
  elastic (elasticsearch + langchain-elasticsearch + opensearch-py)
- bing, cloudflare, maritalk, searchapi, vectara (langchain-community REST wrappers)

Moves each dir into lfx-bundles + fail-soft shim, merges per-provider extras
and regen `all`, appends 4-entry migration block per class (48 entries, 0
ambiguous). Component index regenerated (42->34 categories, 242->230 core
components); uv.lock re-resolved.

Test fixups:
- Repoint baidu/elastic/searchapi backend tests to lfx_bundles.<provider>.
- test_dynamic_imports (lfx isolated suite) used the now-bundled searchapi as
  its fixture; bundles aren't installed in the engine-only lfx env, so switch
  it to the core langchain_utilities.FakeEmbeddingsComponent (same
  langchain_community optional-import path). 131 shim tests + 21 dynamic-import
  tests pass.

* feat(bundles): consolidate homeassistant, olivya, agentql REST providers into lfx-bundles

Third batch (3 providers, 4 components) via consolidate_bundles.py --apply.
These are thin REST wrappers with no dedicated vendor SDK:

- homeassistant (requests) -> lfx_bundles/homeassistant   2 components
- olivya (httpx, lfx core)  -> lfx_bundles/olivya          1 component
- agentql (httpx, lfx core) -> lfx_bundles/agentql         1 component

Moves + shims + per-provider extras + `all` regen; 16 migration entries (0
ambiguous). Component index 34->31 categories, 230->226 components; uv.lock
re-resolved. No tests reference these providers.

Fourth directory-level batch (4 providers, 14 components) via
consolidate_bundles.py. google/vertexai (langchain-google-*), altk
(agent-lifecycle-toolkit), codeagents (smolagents + OpenDsStar); platform/py
markers copied verbatim from langflow-base extras. 56 migration entries (0

* test(lfx): decouple dynamic-import unit tests from soon-to-be-bundled providers

test_dynamic_imports.py and test_import_utils.py used composio/nvidia/huggingface
as the "lazy category whose SDK is absent in the engine-only lfx env" fixture.
That couples the import-mechanism tests to specific providers — they have broken
each time a provider graduated to a bundle (openai/anthropic/chroma -> composio,
now composio et al.).

Switch to stable in-tree core categories:
- files_and_knowledge.KnowledgeComponent for the "missing-dep" path (its module
  imports langchain_chroma / langflow, absent in bare lfx) — works for both the
  import_mod direct calls and the lfx.components hierarchy access.
- helpers / processing for the "imports cleanly" and "module not found" paths.

No behavior change; 43 tests pass in the isolated lfx env. This unblocks moving
composio, huggingface, nvidia, cuga into lfx-bundles without breaking these tests.

* feat(bundles): consolidate composio, huggingface, nvidia, cuga into lfx-bundles

Fifth batch (4 providers, 71 components) via consolidate_bundles.py --apply,
unblocked by the prior dynamic-import test decoupling:

- composio    -> lfx_bundles/composio    (composio + composio-langchain)  63 components
- huggingface -> lfx_bundles/huggingface (langchain-huggingface[marker], huggingface-hub, community)  2 components
- nvidia      -> lfx_bundles/nvidia      (langchain-nvidia-ai-endpoints, nv-ingest-client[py3.12], gassist[win32])  5 components
- cuga        -> lfx_bundles/cuga        (cuga; platform/py markers)  1 component

Markers copied verbatim from langflow-base extras (uv lock --check clean).
284 migration entries (0 ambiguous); component index 27->23 categories,
212->141 components.

Tests: relocate the dedicated lfx-isolated tests for the now-bundled components
to the backend suite (test_nvidia_component.py, test_cuga_session_id_fallback.py)
repointed to lfx_bundles.<provider>; repoint backend composio/huggingface/cuga
imports + a cuga patch target; pragma a fake test api_key. 43 decoupled lfx
import tests pass post-move. SKIP=detect-secrets: only flags are regenerated

* feat(bundles): consolidate langwatch evaluator into lfx-bundles

langwatch -> lfx_bundles/langwatch (1 component). The LangWatchComponent is a
pure httpx REST wrapper (its only non-core touchpoint is lfx.base.langwatch.utils,
which is also httpx-based) — the langwatch SDK extra in langflow-base is for the
tracing service, not this component, so the bundle declares no extra deps.

Moves + shim + `all` regen; 4 migration entries (0 ambiguous). Component index
23->22 categories, 141->140 components. Backend langwatch test repointed
(16 passed). SKIP=detect-secrets: only flags are regenerated component_index
code_hash hex (false positives).

* feat(bundles): consolidate FAISS, Notion into lfx-bundles (lowercase-slug support)

Uppercase source dirs need lowercase bundle slugs (BUNDLE_NAME_RE is
lowercase-only). Enhance consolidate_bundles.py with bundle_slug(provider) =
provider.lower(): the bundle dir, ext id, shim target, and extra key use the
lowercased slug, while the migration import_path keeps the historical
lfx.components.<Provider> casing so saved flows still resolve. Identity for
already-lowercase providers (no change to prior entries).

- FAISS  -> lfx_bundles/faiss  (faiss-cpu[py-split] + langchain-community)  1 component
- Notion -> lfx_bundles/notion (requests + Markdown)  8 components

test_bundle_shims.py: derive the expected bundle name by lowercasing the shim
dir name (FAISS shim aliases lfx_bundles.faiss) — 159 shim tests pass.
Relocate the lfx-isolated FAISS test to backend/vectorstores (repointed to
lfx_bundles.faiss.faiss). 36 migration entries (0 ambiguous); index 22->20
categories, 140->131 components. SKIP=detect-secrets: regenerated code_hash hex.

* feat(bundles): fold vectorstores LocalDBComponent into the chroma bundle

The lone LocalDBComponent is Chroma-backed (eager `from langchain_chroma import
Chroma`), so it belongs in the existing `chroma` bundle rather than a new one —
its deps are already covered by the chroma extra (no new deps).

- Move vectorstores/local_db.py -> lfx_bundles/chroma/local_db.py; register
  LocalDBComponent in the chroma bundle's lazy registry.
- Replace lfx.components.vectorstores with a CROSS-BUNDLE shim aliasing
  lfx_bundles.chroma (dir != bundle).
- Migration: lfx.components.vectorstores[.local_db].LocalDBComponent ->
  ext:chroma:LocalDBComponent@official (4 entries, 0 ambiguous).
- test_bundle_shims.py: add a cross-bundle map {vectorstores: chroma} so the
  shim contract validates (161 shim tests pass).
- Repoint the backend LocalDB test (import + patch target) to lfx_bundles.chroma;
  test_all_modules_importable resolves it via the shim.

Component index 20->19 categories, 131->130 components. SKIP=detect-secrets:
regenerated code_hash hex (false positives).

* feat(bundles): remove unbundleable vlmrun + notdiamond components from lfx core

Per the core-tail audit, four providers couldn't be bundled. vlmrun (imports
`from langflow`, violating the lfx engine boundary) and notdiamond (its
`notdiamond` SDK isn't in the lockfile or any extra, so it can't run) have no
engine references, no starter flows, and no migration-table entries — they're
effectively dead in every distribution, so remove them outright.

(crewai and agentics are kept: crewai is woven into 3 starter-project example
flows, and the core Agent hard-depends on agentics.helpers.model_config — both
need deliberate upstream/refactor work, not deletion.)

- Delete src/lfx/.../components/{vlmrun,notdiamond}/ and drop them from the
  lfx.components top-level registry (TYPE_CHECKING / _dynamic_imports / __all__).
- Regenerate component index (19->17 categories, 130->128 components) and backend
  locales (orphan keys removed; extract_backend_strings --check OK).
- Repoint test_dynamic_imports.test_import_error_handling off the deleted
  notdiamond to the core processing category (43 lfx import tests pass).

SKIP=detect-secrets: only flags are regenerated component_index code_hash hex.

* test(lfx): tie flow-builder search 'returns all' to registry size

The hardcoded `count > 100` assertion predated the bundle-extraction
work, which deliberately moves non-legacy components out of lfx core
(now 66 non-legacy of 128 indexed). Assert the empty-query count equals
the full non-legacy registry instead — the durable 'no query == every
component the registry exposes' contract that survives future bundle
moves.

* fix(bundles): deterministic component alias resolution + sidebar slug casing after bundle move

Moving agentql/composio and the long tail into lfx-bundles made two
shared-label resolutions order-dependent and left two sidebar slugs
mis-cased, surfacing as red CI on the starter-projects template tests
and the bundles-sidebar e2e.

- flatten_components_with_aliases: register every component's identity
  aliases (registry key / ext class name / name) before any component's
  display_name alias, so a component's own class identity always wins
  its key regardless of registry iteration order. A single setdefault
  pass previously let the Composio 'AgentQL'/'SerpAPI' wrappers
  (display_name) shadow the standalone components (class name) depending
  on load order, so update_starter_projects wrote the wrong
  metadata.module into the AgentQL starter node.
- Correct the AgentQL node module in News Aggregator.json and Price Deal
  Finder.json back to lfx.components.agentql.agentql_api.AgentQL.
- SIDEBAR_BUNDLES: lowercase the Notion/FAISS name slugs to match the
  lowercase bundle category names so both bundles render in the sidebar
  again (display_name and icons unchanged).
- Add order-independence regression tests for the identity/display tiers.

* test(weaviate): patch the class's own module, not a fixed string path

The Weaviate component moved into lfx-bundles, so weaviate.py is now
reachable under several module identities (the lfx.components.weaviate
shim, lfx_bundles.weaviate.weaviate, and the runtime _lfx_ext.* copy).
On Python 3.10, unittest.mock resolves a dotted patch target via a
getattr walk that follows the shim's package alias to a *different*
module object than the one the imported class actually lives in, so
patching 'lfx.components.weaviate.weaviate.WeaviateVectorStore' missed
the object the component body reads -> 'WeaviateVectorStore called 0
times' when an earlier test in the group forced the alternate identity.

Resolve the module from the imported class (sys.modules[Cls.__module__])
and patch.object it directly, bypassing dotted-string resolution. Same
fix for AuthApiKey. Order/identity-independent on all Python versions.

* test(ollama,perplexity): patch the class's own module, not a fixed string path

The Ollama and Perplexity components moved into lfx-bundles, so ollama.py
and perplexity.py are now reachable under several module identities (the
lfx.components.<x>.<x> shim, the canonical lfx_bundles.<x>.<x>, and the
runtime _lfx_ext.* ext-loader copy). On Python 3.10, unittest.mock
resolves a dotted patch target via a getattr walk that follows the shim's
package alias to a *different* module object than the one the imported
class / component body actually use, so patching e.g.
"lfx.components.ollama.ollama.ChatOllama" missed the object the body reads
-> "mock called 0 times" depending on suite order.

Resolve the module from the imported class (sys.modules[Cls.__module__])
and patch.object it directly, bypassing dotted-string resolution:
- perplexity: ChatPerplexity -> patch.object(_PERPLEXITY_MODULE, ...)
- ollama: ChatOllama / logger -> patch.object(_OLLAMA_MODULE, ...)
- ollama: ChatOllamaComponent._parse_json_response ->
  patch.object(ChatOllamaComponent, ...) (the imported class itself)
- ollama: httpx.AsyncClient.get/post -> patched on the global httpx
  (a single class object, identity-independent), dropping the shim prefix

Same fix as the Weaviate test (064069b6bb). Order/identity-independent on
all Python versions; the langchain_ollama / lfx.utils.util / socket
patches target stable modules and are left unchanged.

* fix(locales): restore en.json keys for still-shipping spider/policies components

The spider (SpiderTool) and toolguard (PoliciesComponent) components live in
lfx-bundles and still ship in the palette, but their 44 en.json keys were
pruned while all 6 translated locales (de/es/fr/ja/pt/zh-Hans) retained them.
The extractor walks only lfx.components, so bundle-only components with no
compat shim get dropped from en.json on regeneration. Left as-is, the next GP
upload/download cycle would strip ~264 existing translations (44 keys x 6
langs) for two components that are still in the palette.

Restore the 25 spidertool + 19 policies keys to re-align en.json with the
translated locales. (Durable fix — making the extractor walk src/bundles and/or
adding lfx.components shims for these two providers — is a follow-up, since
spider.py eager-imports its SDK and a shim alone won't make it walkable.)

* chore(deps): drop dead astradb/graph-retriever extras and langchain-aws from langflow-base

After datastax/amazon graduated to lfx-datastax/lfx-amazon, langflow-base still
declared astradb (langchain-astradb), graph-retriever (langchain-graph-retriever,
graph-retriever) and langchain-aws in its aws extra -- all pulled into the
complete aggregate -- though zero core .py files import them (the consuming
components moved to the bundles, which re-declare the same deps). This duplicated
the SDKs in every pip install langflow and was inconsistent with the
openai/anthropic/cohere extras already removed in this PR.

Remove the astradb and graph-retriever extras and their complete refs, and drop
langchain-aws from the aws extra (boto3 stays -- it backs langflow-base's own S3
storage, not just the amazon components). Regenerate uv.lock; closure unchanged,
the SDKs still resolve via lfx-datastax/lfx-amazon.

* ci(extension-migration): enforce component os.environ-write lint in CI

check_component_env_writes.py guards against components writing to process-global
os.environ (which bleeds one caller's credential into other requests on a warm
worker). It was wired only as a pre-commit hook, bypassable via git commit -n,
web-UI commits, or uninstalled hooks. Add it as a stdlib-only job in
extension-migration-checks.yml next to freeze-components, so the credential-bleed
guard is enforced in CI regardless of local pre-commit.

* test(bundles): cover migration-table completeness, preflight provider path, frozen gate

Three test-coverage gaps from the metapackage split, all green on the current tree:
- migration-table completeness: parametrized sweep asserting every lfx_bundles
  provider component class (196 across 72 providers) is reachable via
  migration_table.json as an ext:<provider>:<Class>@ target, so a provider moved
  into a bundle without a table entry fails CI instead of silently breaking saved
  flows. Includes a negative control.
- dependency preflight provider path: drives find_missing_dependencies and
  _preflight_dependencies through a node with a model/agent_llm provider field so
  the _PROVIDER_PACKAGE_FALLBACKS path (the only working provider-dep source in
  engine-only installs) is exercised.
- frozen-components gate: unit tests for check_components_frozen.py covering
  additions (fail), removals (allowed), and the init/pycache/dotdir and
  comment-parsing rules.

* chore: auto-bake note keys and regenerate backend locales/en.json [skip ci]

* fix(locales): make spider/toolguard i18n keys survive regen via shims

The earlier restore of the 44 spider/policies en.json keys was reverted by the
gp-backend-check bot: it auto-regenerates en.json on every push to this PR (the
PR-level path filter matches the bundle moves under lfx/components) and the
bundle-blind extractor could not reproduce the keys.

Make them durable the way every other moved provider does:
- Add lfx.components.spider and lfx.components.toolguard '# lfx-bundles-shim'
  packages re-pointing to lfx_bundles.{spider,toolguard}, so the extractor (which
  walks lfx.components) emits SpiderTool/PoliciesComponent keys again.
- Lazy-import spider's SDK (from spider.spider import Spider moved into crawl())
  so SpiderTool is importable for extraction/registration without spider-client,
  matching the lazy pattern weaviate/zep already use (toolguard was already lazy).
- Add spider/toolguard to scripts/ci/frozen_component_dirs.txt so the
  additions-only freeze gate accepts the new shim dirs.
- Restore the 44 keys to en.json.

Verified the extractor now reproduces exactly the 44 keys (25 spidertool + 19
policies), so the bot keeps them instead of dropping them. Bundle components are
dynamic-only (not in component_index.json), so no index regen is needed.

* chore(bundles): declare astrapy in lfx-datastax; align lfx-ibm manifest version

- lfx-datastax imports astrapy directly (astrapy.DataAPIClient/Database in the
  astra components) but only pulled it transitively via langchain-astradb.
  Declare it explicitly, pinned to match langflow-base's astrapy extra
  (>=2.1.0,<3.0.0).
- lfx-ibm's extension.json reported version 0.1.0 while pyproject.toml is 0.1.1;
  the loader uses the manifest version, so bump it to 0.1.1 to match.
Regenerate uv.lock (closure unchanged; astrapy was already resolved
transitively).

* refactor(migrate): guard consolidate against subdir data loss; fix alias docstring

- consolidate_bundles.move_provider copies only top-level *.py but rmtree's the
  whole source tree, so a provider with a subpackage would have its subdir
  silently destroyed and never migration-mapped. Refuse with a clear error
  instead of half-moving (port_bundle.py handles nested layouts). No current
  PROVIDER_DEPS entry has a subdir, so this is a defensive guard.
- component_aliases: the order-independence docstrings overclaimed. Scope the
  guarantee to identity-beats-display (and real-key-beats-alias) and note that
  two components contributing the same identity alias remain first-wins by
  iteration order.

* ci(gp-backend): regen en.json on src/bundles/** edits

The gp-backend-check bot regenerates locales/en.json on PR changes, but its
path filter only watched src/lfx/src/lfx/components/**. Bundle component
strings reach core en.json through the lfx/components/<provider> import shims
(e.g. spider, toolguard), so editing a bundle's display_name/description/info
under src/bundles/** would not re-trigger the extractor and en.json could
silently drift from the translated locales. Add src/bundles/** to the trigger
so bundle-side string edits keep en.json aligned; regen is diff-gated, so
non-string bundle edits remain a no-op.

* fix(bundles): Policies in Models & Agents core; Spider in bundles sidebar

Policies (toolguard) component:
- Move PoliciesComponent + policies/ helpers out of the lfx-bundles
  consolidated metapackage back into lfx/components/models_and_agents core
  (restores the main/release-1.11.0 layout); register it in the category
  __init__ and restore the core-path tests.
- toolguard stays an optional langflow-base extra (langflow-base[toolguard],
  pulled in via [complete]); the component imports it lazily, so a bare lfx
  install still loads/inspects it.
- Remove the lfx-bundles toolguard provider (dir + extra + [all] entry), the
  lfx core import shim, and the frozen_component_dirs.txt entry; drop the 4
  ext:toolguard migration entries; regenerate component_index (128 -> 129)
  and uv.lock.

Spider:
- Add spider to SIDEBAR_BUNDLES so it renders in the Bundles section like
  arXiv instead of falling into the default categories (it was missing from
  the list while peer lfx-bundles providers were present).

* docs(bundles): fix error-tier mirror claim, list-time discovery note, metapackage README

Addresses three documentation nits from the PR #13563 re-review:

- errors.py: the lfx.bundles diagnostics comment claimed a full mirror of the
  inline tier's split, but only the duplicate case matches. name-invalid and
  root-unreadable are warning-only here where their inline counterparts are
  hard errors (ok=False). Tighten the comment to match actual behavior.
- BUNDLE_API.md: note that manifest-less lfx.bundles providers are invisible to
  `lfx extension list` (discover_all_extensions walks only installed + seed;
  load_lfx_bundles_extensions runs in the startup component-loading path), so
  the precedence story isn't read as a list-time property.
- lfx-bundles/README.md: the bulk move has landed on this branch (71 providers,
  populated per-provider extras, generated `all`), so drop the "empty skeleton /
  available later" framing and document the final state.

* fix(bundles): surface pip-install guidance for missing SDKs on the server run path

A flow loaded through the UI/API on an engine-only `lfx` (no bundles)
failed deep in the vertex build with a bare
`Error creating class. ModuleNotFoundError(No module named 'langchain_chroma')`.
The actionable install guidance only existed on the `lfx run` preflight
and the legacy import shim; the server run path
(simple_run_flow -> run_graph_internal -> graph.arun()) had neither.

Both vertex-build error formatters (lfx's `format_exception_message`, used
by graph.arun(), and langflow's, used by the build/chat endpoints) now
detect a plain ModuleNotFoundError in the cause chain and attach the same
`pip install <package>` guidance the CLI gives, mapping the missing import
to its PyPI distribution via the existing requirements resolver. Bundle-shim
"components moved to ..." messages are left untouched (their message does
not start with "No module named"), so graduated providers stay actionable.

* fix(bundles): surface curated shim message over its raw cause in exception formatter

get_causing_exception walked to the deepest __cause__, so a graduated
provider's curated "components moved to ..." ModuleNotFoundError (raised
`from` the raw "No module named 'lfx_<x>'") was unwrapped past it. The
formatter then regenerated bare "pip install lfx-<x>" guidance, dropping
the curated text — including the "or pip install langflow, which bundles
it" clause.

Both get_causing_exception copies (lfx + langflow) now stop at the first
ModuleNotFoundError whose message is not a raw "No module named ..." (the
curated shim error), and module_not_found_hint surfaces that curated
message verbatim. Plain SDK import errors are unchanged.

Adds regression tests reproducing the real 3-level cause chain on both
formatters; the old test used a truncated chain that hid this.

* fix(bundles): cover OpenRouter/IBM WatsonX in Orchestrate requirements detection (#13732)

fix(bundles): cover OpenRouter/IBM WatsonX in wxO requirements detection

The bundle split removed the langchain provider SDKs from lfx's own
dependency tree, which makes flow→requirements detection load-bearing for
Watsonx Orchestrate deployments: the runner installs only `lfx` + the
packages `generate_requirements_from_flow` emits, so a provider missing
from the resolution tables yields an empty requirements set and the
deployed flow fails to import its model class.

Two unified-selectable providers were unresolved:
- OpenRouter (runs on ChatOpenAI) was in no resolution table -> [].
- "IBM WatsonX" (catalog casing) only matched the legacy "IBM watsonx.ai"
  key; langchain-ibm landed only by an embedding-path coincidence.

Add both to _PROVIDER_PACKAGE_FALLBACKS (keyed by the exact catalog
strings) so every provider in MODEL_PROVIDER_METADATA resolves.

Tests:
- TestBundleSeparationOrchestrate in test_flow_requirements.py: catalog
  coverage guard, OpenRouter/IBM regressions, and split-contract guards
  (bundle dists and langchain imports must stay out of lfx's tree).
- End-to-end artifact tests in test_watsonx_orchestrate.py asserting a
  bundle-provider flow emits the langchain SDK (not lfx-openai/lfx-bundles)
  and that requirements.txt pins lfx as its first line.

* Backend format

* Format again

* [autofix.ci] apply automated fixes

* fix(bundles): pin datastax ruff line-length to 120 to stop format tug-of-war

The datastax bundle's pyproject.toml declares a [tool.ruff.lint.per-file-ignores]
table, which makes ruff treat the directory as a standalone config root. It never
restated line-length, so ruff fell back to its default of 88 there. As a result
`make format_backend` (per-directory config discovery) wrapped lines to 88 while
the pre-commit ruff-format hook (run with --config pyproject.toml, forcing the
repo-wide 120) unwrapped them back, leaving the two formatters fighting forever.

Restate line-length = 120 so both config-resolution paths agree. Use the explicit
line-length rather than extend=../../../pyproject.toml to avoid pulling in the
root lint ruleset, which the bundle intentionally does not enforce.

* fix(bundles): relocate notdiamond + vlmrun into lfx-bundles

Both providers were dropped during the bulk long-tail move with no bundle
and no compatibility shim, removing them from the registry,
component_index, migration table and locales. That breaks saved flows
using the NotDiamond Router or VLM Run Transcription nodes (vlmrun ships
in langflow[complete]), contradicting the zero-user-facing-change goal.

Relocate both the same way as the other long-tail providers:
- move implementations into src/bundles/lfx-bundles/src/lfx_bundles/
- restore lfx.components.{notdiamond,vlmrun} marker shims
- re-register both in lfx/components/__init__.py
- add per-provider extras (vlmrun -> vlmrun[all]) and the 'all' aggregate
- add migration_table targets ext:{notdiamond,vlmrun}:<Class>@official
- restore the 32 en.json strings; refresh uv.lock

* docs(lfx): correct dependency-preflight scope to lfx run only

The preflight is wired into 'lfx run'; 'lfx serve' has its own
module-not-found hint at request time and does not call it.

f85a32a052 feat: native v2 workflows endpoint with pluggable stream protocols (#13307)
* feat: native v2 workflows endpoint with pluggable stream protocols

Rebased onto release-1.10.0. The base independently rebuilt the v2
workflows backend (RBAC, body globals, share-aware fetch); keep our
forward design and conform its auth to that work:

1. Auth: keep get_current_user_for_workflow (session-or-API-key authN
   that does not hold a DB connection during the inline run, avoiding
   the SQLite lock contention api_key_security would cause) and enforce
   the base's RBAC on top: ensure_flow_permission(EXECUTE) before run,
   (READ) before status reconstruct, with widen_for_shares fetch.
2. Port the base's request-body globals onto the v2 WorkflowRunRequest.
   The X-LANGFLOW-GLOBAL-VAR-* headers stay supported (the Responses API
   passes globals that way); body globals win on conflict. Converters
   echo the effective globals via effective_globals.
3. Public endpoint keeps the v1 build_public_tmp posture
   (access_type==PUBLIC, run-as-owner); RBAC applies to the
   authenticated endpoint only.
4. Preserve the base's post-build KB-cache invalidation in the AG-UI
   build path.

The endpoint, AG-UI bridge, pluggable stream adapters, public endpoint,
and re-attach are unchanged.

* feat(api): add output_text and session_id to v2 workflow response

The synchronous /api/v2/workflows response keyed every result under its
component id, so reading the answer meant knowing an id you can't predict.
Surface two additive fields:

- output_text: the flow's single text answer (ChatOutput/TextOutput). None
  when the flow has zero or multiple text outputs, so callers read outputs
  rather than the shortcut guessing which channel is the answer.
- session_id: echoes the resolved session so chat/memory callers can
  continue the same thread (v1 /run returned this; v2 had dropped it).

outputs is unchanged, so this is non-breaking.

* test(api/v2): cover output_text and session_id on the v2 workflow response

Pin the sync-response shortcuts on the v2 workflows endpoint:
- output_text surfaces the lone ChatOutput/TextOutput text and stays None for
  non-output message nodes, data-only flows, and multi-text flows
- session_id echoes the resolved session; the error response exposes neither
- each outputs entry exposes only {type, status, content, metadata}, with the
  component id carried by the dict key

Also drop the component_id kwarg the converter passed to ComponentOutput, which
has no such field and silently dropped it.

* feat(api/v2): structured output with resolution reason on v2 response

Replace the flat output_text shortcut with an `output` object carrying the
resolved text answer plus a `reason` that explains why it resolved that way
(single/multiple/none/non_string/failed), so a null answer is always
diagnosable instead of silently None. `reason` follows the LLM-domain
finish_reason/stop_reason convention, distinct from the lifecycle status.

Also add `display_name` to each ComponentOutput (the stable component id
stays the dict key) and a computed `has_errors` flag derived from errors.

* feat(api/v2): add request-side output selection (output_ids)

Let a sync caller name the output(s) they want via output_ids so
output.text resolves deterministically (reason=single) on multi-output
flows instead of going null. Selection is steer-only: it picks the
answer among the named outputs without filtering the outputs map.

Invalid ids are rejected with 422 before the flow runs (and before any
job row is created), so a typo costs no compute. Resolution considers
selected outputs that actually fired, so branching flows resolve to
whichever candidate ran.

* feat(api/v2): emit per-output events on the langflow stream

Give v2-workflows sync and the langflow stream protocol one parser. The
stream now emits a normalized "output" event per terminal output carrying
an OutputEvent (the ComponentOutput shape sync returns in outputs[id], plus
component_id). A shared build_component_output() backs both the sync
converter and the adapter, and the build loop ships authoritative vertex
metadata as an additive output_meta key on end_vertex (existing consumers
read build_data and ignore it).

This is access-pattern parity (one parser, same fields, same terminal set),
not byte-identical content: the stream reuses the v1 build path whose
display serialization differs from sync's run_graph output.

* fix(api/v2): enforce no-code-execution gate on public workflow endpoint

The v2 public endpoint only ran validate_flow_for_current_settings and
skipped validate_public_flow_no_code_execution, which the v1
build_public_tmp path applies. A public flow containing a Python
interpreter/REPL (or the legacy Python Code Structured tool, Smart
Transform lambda) was therefore an unauthenticated server-side
code-execution primitive (report H1-3754930).

Mirror v1: import the validator and call it right after the
public-access gate. PublicFlowValidationError subclasses
CustomComponentValidationError, so the existing handler already
sanitizes it to a 400 'This flow cannot be executed.' without leaking
the blocked component class names.

Add a non-mocking test that builds a public flow with a real
PythonREPLComponent and asserts the sanitized 400 (verified RED: returns
200 without the gate).

LE-1389

* fix(api/v2): reconstruct background workflow status from job-keyed vertex builds

A completed background job's GET status 500'd with 'No vertex builds found
for job_id'. The background build path differed from the sync path twice:

1. generate_flow_events minted a fresh run_id instead of using job_id, so
   vertex builds were keyed by an id the status query never uses. Thread
   run_id through _stream_event_frames -> generate_flow_events and pass
   job_id from the background buffer so graph.run_id == job_id (the sync
   path already does graph.set_run_id(job_id)).

2. The SSE build loop (build_vertices) only persisted builds when log_builds
   was set and never passed job_id. Tie log_builds to job-tracked runs
   (run_id present) and pass job_id=graph.run_id on the persist call.
   Job-tracked runs also persist streaming terminal vertices so
   reconstruction is complete; the live build path (run_id is None) keeps
   its original behavior, so the v1 build path is unchanged.

Test: a real background run polled to completion, then GET status asserts a
reconstructed 200 (verified RED: 500 'No vertex builds found' before the
fix). Covers the non-streaming flow. v1 build path unchanged (35 build
tests pass); AG-UI suite 46 pass.

LE-1389

* fix(api/v2): merge workflow AG-UI cancellation hardening LE-1389

* fix(api/v2): signal cross-worker workflow stops LE-1389

* fix(api/v2): report unconfirmed workflow stops LE-1389

* fix(api/v2): keep background workflows out of polling watchdog LE-1389

* fix(api/v2): buffer parallel messages in the AG-UI translator instead of dropping them

Parallel components stream tokens for different message ids interleaved.
The translator tracked a single open message: the first foreign token
closed the open message and tombstoned its id, so every later event for
it was dropped and its remaining text never reached the client.

Tokens for a message that cannot take the wire now buffer until the open
message genuinely ends (its add_message finalizer), then flush in arrival
order; complete messages landing mid-stream buffer the same way instead
of interleaving a second START. end/error drain all buffers before the
terminal event. The wire still carries at most one open text message, so
the stream stays AG-UI-conformant.

* fix(api/v2): gate AG-UI message finalization on non-partial state and purge removed buffers

A partial add_message re-fire (the agent path emits these at tool
start/end for a message it is still streaming) was treated as the
finalizer: it closed and tombstoned the id, so the post-tool answer
was dropped. Only a non-partial add_message finalizes now; state
defaults to complete, so payloads without properties are unchanged.

remove_message now purges a buffered message and tombstones its id,
so text the backend retracted is not flushed to the client later.

* Fix AG-UI workflow lifecycle edges

* [autofix.ci] apply automated fixes

* fix(frontend): enable downlevelIteration for jest Set/Map iteration

ts-jest compiles with target es5; without downlevelIteration, [...set] and
for...of over a Set/Map emit ES5 that yields nothing. That silently broke the
AG-UI bridge tests: runningNodeIds spread, markRunningNodesFailed, and
restoreOriginalBuildStatuses all iterated empty. Production (Vite/SWC, modern
target) was never affected; only the ts-jest harness was. Fixes the 3 failing
jest tests on this branch with no other suite changes (4994/4994 pass).

* fix(api/v2): surface inactivated branch vertices over AG-UI

A branch component (If-Else, Conditional Router) reports its not-taken
vertices in build_data.inactivated_vertices, but the AG-UI translator only
emitted the branch node's own success/error status and dropped that list. The
canvas seeds every planned node as pending from vertices_sorted; skipped
vertices then get no build_start/end_vertex, so they stayed stuck on pending
instead of rendering as inactive (the v1 build path marked them INACTIVE).

The translator now appends an inactive STATE_DELTA op per inactivated vertex,
and the frontend bridge maps the new inactive status to BuildStatus.INACTIVE
and tears its edges down like a completed node. Fixes the If-Else regression
in general-bugs-reset-flow-run.spec.ts.

* fix(api/v2): dedupe repeated inactive node deltas in AG-UI stream

build.py keeps reporting a conditionally-excluded vertex in
inactivated_vertices on every subsequent end_vertex (the excluded set
persists until the ConditionalRouter clears it), so the translator was
putting the same inactive STATE_DELTA on the wire once per remaining
vertex. Track emitted inactive nodes and skip re-emitting; drop a node
from the set when it actually runs again (build_start/end_vertex) so a
loop re-activation can still re-emit inactive later.

* fix(api/v2): address review findings on the v2 workflows endpoint

- recover session_id for completed background jobs from the persisted
  terminal message instead of always returning null, so GET status can
  continue the same chat/memory thread
- replay a user-cancel as a CUSTOM cancel marker + RUN_FINISHED (agui) and
  a `cancelled` terminal (langflow) instead of RUN_ERROR, so a re-attaching
  client no longer reads a deliberate stop as a failure
- cancel the evicted still-running buffer writer when the background-run
  registry is full, so it stops appending into a run no reader can find
- derive per-component status from the error artifact / valid flag instead
  of hardcoding COMPLETED, and stop the langflow adapter dropping `valid`
- throttle the unauthenticated public endpoint per IP and bound its
  input_value/session_id length
- document the sync-only scope of request-body globals
- document that live event re-attach is intentionally owner-only

* test(lfx): register public_flow_rate_limit_per_minute in settings composition

* refactor(v2 workflows): split workflow.py and address review blockers

Splits the ~1.5k-line workflow.py into focused modules and folds in the
execution-timeout and error-sanitization fixes from Cristhianzl's review of #13307.

- B1: workflow.py now holds only the four route handlers. Validation guards move
  to workflow_validation, the sync/stream run loop to workflow_execution, and the
  durable background machinery to workflow_background (layered, acyclic).
- I1: add workflow_execution_timeout (default 300) and apply a single wall-clock
  ceiling across sync, stream, background, and public via _stream_event_frames. A
  timeout becomes a sanitized terminal error and marks a background job failed.
- I3: the route error handlers no longer echo raw exception text. They return a
  generic, code-tagged message and log the full exception server-side.
- R1: remove the "commented out / future scope" comments that sat over live
  dataframe-extraction code in converters.py.
- R4: drop the worker-routing internals from the reattach 409 message.

Tests cover the timeout terminal-error path and the error-body sanitization, and
the settings field-count guard is updated for the new setting.

309a558b55 chore(deps): bump toolguard floor to 0.2.20 (#13769)
toolguard 0.2.20 ships the Windows build-time code-generation fixes from
AgentToolkit/toolguard#28 (repr()-embedded paths in the pytest runner,
utf-8 file reads, and pyright executable resolution). Raising the floor
from 0.2.16 to 0.2.20 guarantees Windows users get the working green-loop
codegen rather than the silent stub fallback, completing the langflow-side
Policies/ToolGuard Guard-mode fix (#13751).

The existing toolguard.runtime circular-import structure is unchanged in

59e03266c7 feat(lfx): verified-JWT identity forwarding for lfx serve (#13632)
* feat(lfx): verified-JWT identity forwarding for lfx serve

Add an optional per-user identity layer to `lfx serve` so the edge gateway's
authenticated caller is threaded into flow execution as `user_id`. Identity
must arrive as a cryptographically verifiable JWT by default; plain gateway
headers are accepted only under an explicit, weaker trust mode.

- serve_identity.py: IdentityConfig (off / jwt / header modes, env round-trip)
  and IdentityVerifier (pyjwt) with algorithms pinned to RS256/ES256 (rejects
  alg:none and HMAC alg-confusion before any crypto), exact iss, aud
  containment, exp/nbf with skew, and a per-process TTL'd JWKS cache with
  startup prefetch, rate-limited refresh, and keep-cache-on-fetch-failure. The
  raw token never reaches a log line or error body.
- Wiring: /flows/{id}/run and /stream gain an identity dependency that
  sub-depends on verify_api_key, so identity only annotates requests that
  already cleared the serve-key floor. execute_graph_with_capture threads the
  resolved user_id through run + stream paths and graph.user_id.
- CLI options propagated to uvicorn workers via LFX_SERVE_IDENTITY_* (each
  worker keeps its own JWKS cache).
- Startup notices (failed JWKS prefetch, header-mode trust warning) are emitted
  on a guaranteed stderr console as well as the logger, since the structlog
  logger is not reliably surfaced on the serve stdout path under uvicorn.

Tests use a locally generated RSA keypair and an in-memory fake JWKS (no
network) covering off-mode regression, identity threading, the reject matrix,
rate-limited refresh, warm-cache resilience, prefetch recovery, header mode,
the serve-key floor, multi-worker env round-trip, and token-never-logged.

* [autofix.ci] apply automated fixes

* fix(lfx): require HTTPS for JWKS/issuer and fail closed on malformed JWKS

Security: plaintext http:// JWKS/issuer URLs are MITM-able — an attacker who
tampers with the response serves their own JWKS and forges tokens with the
expected iss/aud. Require https:// by default for the JWKS URL and the
issuer-derived OIDC discovery URL (and the discovered jwks_uri), with an
explicit --identity-jwt-allow-insecure-http / LFX_SERVE_IDENTITY_ALLOW_INSECURE_HTTP
escape hatch for local/dev. Non-http(s) schemes remain refused.

Availability: malformed external JSON (a JWKS or OIDC discovery doc that is a
JSON array rather than an object, or a non-string jwks_uri) raised an uncaught
AttributeError out of prefetch/request handling — aborting startup or 500ing a
request instead of failing closed. Guard the shapes and raise IdentityConfigError
so they funnel into the existing fail-closed (401) path.

Also adds ES256 unit coverage (the second accepted algorithm was only exercised
manually before).

Tests: +14 (HTTPS policy + escape hatch, malformed-shape fail-closed, ES256).

* fix(lfx): resolve identity OptionInfo leak and ANSI-fragile help assertion

serve_command declared the identity params as typer.Option(...). Direct
(non-CLI) callers that omit them got the raw OptionInfo as the value, so
IdentityConfig(mode=<OptionInfo>) raised on every serve. Convert them to
plain defaults (the CLI options live on serve_command_wrapper), completing
the pattern already applied to identity_jwt_allow_insecure_http.

Also strip ANSI before the serve --help substring assertion: rich colorizes
each hyphen-segment of an option name, so '--identity-mode' is never a literal
substring when color is forced (as in CI).

Additionally reject whitespace-only identity claims, not just empty/None, and
cover it with a parametrized test.

* Fix jwks fetch to use httpx client, avoiding redirects

* [autofix.ci] apply automated fixes

* fix(firecrawl): map Search component to Firecrawl icon, drop Extract

The frontend icon map in styleUtils.ts still referenced the removed
FirecrawlExtractApi and lacked the new FirecrawlSearchApi, so the Search
node would not render the Firecrawl logo.

* chore: regenerate component index for Firecrawl v2 (Search added, Extract removed)

* refactor(firecrawl): extract components into the lfx-firecrawl extension bundle

Port the firecrawl provider out of lfx.components into a standalone
Extension Bundle at src/bundles/firecrawl (distribution: lfx-firecrawl),
following src/bundles/PORTING.md:

- Move the v2-SDK components (Scrape, Crawl, Map, Search) to
  src/bundles/firecrawl/src/lfx_firecrawl/components/firecrawl/ and
  remove the in-tree provider + its lfx.components registration.
- Own the firecrawl-py>=4,<5 pin in the bundle; drop it from
  langflow-base.
- Wire the workspace (root pyproject deps/sources/members) and uv.lock.
- Append migration-table entries (bare name, both import paths, pre-a
  slot) for the four classes; FirecrawlExtractApi gets no entries since
  the v2 SDK removed the extract endpoint and the component was dropped.
- Regenerate the component index (firecrawl category removed) and
  locales/en.json (54 firecrawl keys move out of core).
- Bundle-local unit tests + test_pilot_firecrawl_upgrade integration
  test; update Dockerfile bundle enumeration comments.

* fix(lfx): repair migration table entry fused during release-1.11.0 merge

The release-1.11.0 back-merge collided the FirecrawlSearchApi legacy_slot
entry with the NextPlaidVectorStoreComponent bare_class_name entry, mashing
both into a single object with duplicate 'target' keys, populating two of
{bare_class_name, import_path, legacy_slot}. That fails the MigrationTable
validator (entries.51) and broke the lfx loader tests.

Split it into the two intended entries so each populates exactly one
key-field. Restores the FirecrawlSearchApi and NextPlaidVectorStoreComponent
quads (60 entries total, +16 vs base). Append-only and bare-name guards pass.

40d7814739 feat: New Bundle support for Multi-vector NextPLAID vector store (#13553)
* nextplaid integrate

* doc ids fix

* multivec fixes

* type check

* refactor: ship NextPlaid as the lfx-nextplaid extension bundle

Convert the in-tree NextPlaid vector store and its companion vLLM
multivector embeddings into a standalone `lfx-nextplaid` Extension Bundle,
following src/bundles/PORTING.md (cf. lfx-arxiv, lfx-ibm). The whole
feature now ships as an additive bundle with no core modifications.

- Move both components into src/bundles/nextplaid (components/nextplaid),
  dropping src/lfx/.../components/nextplaid and reverting the core vllm
  __init__ multivector additions.
- Bundle declares its own runtime deps (langchain-plaid, pillow) and ships
  extension.json + the langflow.extensions entry point.
- Add migration_table entries mapping the legacy class names / import
  paths to ext:nextplaid:*@official; wire the workspace (root pyproject,
  uv.lock).
- Add the pilot upgrade integration test and bundle-local unit tests.
- Declare explicit outputs on NextPlaidVectorStoreComponent so the
  extension validator can resolve its output methods.

* fix: address CodeRabbit review on NextPlaid bundle

- nextplaid: derive stable text IDs from source/page+content (not content
  alone) and fingerprint raw PIL images by bytes (not batch position) so
  ingests upsert instead of colliding/overwriting unrelated vectors
- vllm impl: validate the /pooling response envelope before nested indexing,
  raising a clear RuntimeError on malformed text/image responses
- icon: use the isDark boolean prop contract instead of the isdark string
- test: gate the distribution check on package presence (PackageNotFoundError)
  so genuine import failures surface instead of being skipped

6610091697 fix(bundles): republish lfx-* at 0.1.1 with corrected pin + relax lfx floor for RC builds (#13542)
* fix(bundles): bump lfx-* bundles to 0.1.1 to republish with corrected lfx pin

The published 0.1.0 artifacts on PyPI carry stale lfx pins from before the lfx 0.5.0->1.10.0 version realignment:

- lfx-arxiv, lfx-duckduckgo: lfx>=0.5.0,<0.6.0 (hard-broken; the <0.6.0 cap can never resolve lfx 1.10.0)
- lfx-docling, lfx-ibm: lfx>=0.5.0 (uncapped floor/cap mismatch)

The source pin was already corrected to lfx>=1.10.0,<2.0.0 in #13516, but the bundles were never re-published. PyPI versions are immutable, so shipping the fix requires a version bump. Bump all four to 0.1.1 so the Release Bundles workflow cuts fresh wheels carrying the correct pin. Root pyproject keeps its >=0.1.0 floors (satisfied by 0.1.1); only the bundle dist versions and their uv.lock stamps change.

* fix(release): relax bundle lfx floor for pre-release builds + idempotent bundle publish

The RC pre-release run builds lfx as 1.10.0rc0, but bundles floor lfx at >=1.10.0. Under PEP 440 a pre-release sorts below the final, so 1.10.0rc0 fails >=1.10.0 and the cross-platform install test cannot resolve the bundle wheels against the RC lfx wheel.

build-base/build-main/build-lfx already rewrite their inter-package deps to the pre-release version when pre_release=true; build-bundles was the only release artifact missing that step. Add it: when pre_release=true, rewrite each bundle's lfx floor to the exact pre-release version, keeping the wide <2.0.0 BUNDLE_API cap. Stable source stays at >=1.10.0 -- only RC wheels are relaxed, at build time, so no source churn or re-tag.

Also make publish-bundles tolerate 'already exists' duplicate wheels on rerun, matching release_bundles.yml.

- Tighten langflow-base lfx pin: ~=0.5.0 → ~=1.10.0
- Fix release.yml pre-release boundary from next-major to next-minor (<X.(Y+1).dev0)
- Add minor-parity soft check to scripts/release-lfx.sh

- Move Mapping import under TYPE_CHECKING to satisfy Ruff TC003
- Assert fixture flows and registry are non-empty so parametrized tests cannot pass vacuously
- Remove unused capsys arg and replace print with sys.stderr.write (Ruff T201/ARG001)
- Add upgrade_flow param to run command docstring

* fix(lfx/upgrade): preserve envelope on run, apply nested upgrades (#13200)

* fix(lfx/upgrade): preserve envelope on run, apply nested upgrades

Three follow-ups on top of the upgrade tooling:

- run --upgrade-flow: re-attach the inner graph to the outer envelope before handing the flow to aload_flow_from_json. Previously the upgrade path unwrapped {"data": ...} and passed the inner dict to the loader, which raised KeyError: 'data'. Adds happy-path tests for envelope and flat file inputs.
- applier: recurse into one level of nested flow nodes (node.data.node.flow.data.nodes), matching the checker. Without this, outdated_safe nodes inside grouped components were reported but never written. Adds a regression test.
- upgrade --write test: assert the envelope is preserved (name, description, endpoint_name, etc.) instead of the previous unwrapped-output expectation, so the test matches the actual fix in this PR.
- Drive-by ruff cleanup: D417 docstring, SIM103, SIM108, E501, RUF059.

* fix(lfx/upgrade): fix loader KeyError, outer-envelope checker gap, and nested-node applier

Three bugs from ogabrielluiz's PR review:

1. run/base.py loader KeyError: file-path branch unwrapped the outer envelope
   for the checker but passed the inner dict to aload_flow_from_json, which does
   flow_graph["data"] unconditionally. Re-wrap as {"data": flow_dict} before the
   loader call. Applied consistently to all three input paths (--flow-json,
   --stdin, file-path).

2. run/base.py zero-node checker for --flow-json/--stdin: those paths stored the
   raw parsed JSON without unwrapping, so a caller passing an exported flow
   {"name":..., "data":{...}} caused the checker to see zero nodes and silently
   pass. Now unwrap with raw.get("data", raw) matching the file-path branch.

3. applier.py nested flows never upgraded: the early `continue` on top-level
   nodes not in safe_ids prevented the nested-node loop from running. Restructured
   so the nested check fires unconditionally for every top-level node, mirroring
   checker.py:160-165.

* fix(lfx/run): unify outer-envelope unwrap across all --upgrade-flow input paths

File-path reads now call raw.get("data", raw) matching --flow-json and
--stdin, so the upgrade checker always sees the inner graph. This also
removes the has_envelope/re-wrap machinery that was double-wrapping
outer-envelope files when passing to aload_flow_from_json.

Fix two test assertions that described the old double-wrapped shape.

* fix(lfx/upgrade): inject registry into upgrade_command; fix Makefile lfx pin regex

- upgrade_command now accepts an optional registry parameter so tests
  can pass the dict directly instead of mocking load_registry_from_index
- Makefile sed regex broadened from \"lfx~=.*\" to match both ~= and >=
  forms so make patch works after release.yml rewrites the pin
- Echo label changed to LFX (synced) to clarify the variable is the
  shared Langflow version, not a separate LFX-specific value

* fix(make/patch): fix langflow-base sed regex and validation grep

The dependency in pyproject.toml is "langflow-base[complete]>=X.Y.Z",
not the "langflow-base==X" form the original regex expected, so make
patch silently left the pin unchanged and the validation step always
failed. The sed pattern now matches any extras/operator combination and
rewrites to the canonical [complete]>= form; the grep uses -F so the
[complete] brackets are treated literally.

* test(lfx): add patch regex tests and symmetric safe-mode envelope tests

test_patch_regexes.py — 15 tests covering the Python regexes embedded in
the Makefile patch target. Exercises all three substitutions (langflow-base
pin, lfx pin, version field) against every realistic pin format including
the >=X.Y.Z,<dev0 form that release.yml writes. Would have caught the
langflow-base==.* vs [complete]>= mismatch before manual testing.

test_base.py — two new TestUpgradeFlowOption tests:
  test_upgrade_flow_safe_envelope_inline_json_loads_successfully
  test_upgrade_flow_safe_envelope_stdin_loads_successfully
Symmetric to the existing file-path envelope test; verifies that --flow-json
and --stdin with an outer-envelope flow also pass {"data": inner} to the
loader after safe upgrades, not a double-wrapped {"data": outer_envelope}.

* fix(lfx/upgrade): address review: compat checker, shared gate, fail-fast registry

Checker correctness:
- _outputs_are_compatible: drop cosmetic display_name from the breaking check;
  treat widened output types as safe (flow types must be a subset of registry
  types), only narrowing breaks downstream edges.
- _input_types_contained: stop flagging widened input_types as breaking; keep
  narrowing as the only breaking case; fix misleading comments.
- check_flow_compatibility now recurses fully into nested grouped components
  (symmetric with the applier) and accepts a pre-built registry lookup.

CLI/run/serve:
- New lfx.upgrade.cli_gate (UpgradeFlowMode enum, UpgradeFlowError,
  apply_upgrade_gate) shared by run_flow and serve_command so the two
  --upgrade-flow paths can't diverge.
- run_flow: extract _materialize_flow_dict and route gating through the shared
  helper.
- run/serve --upgrade-flow options typed as UpgradeFlowMode (check|safe choices).
- lfx upgrade: load_registry_from_index fails fast when the bundled registry is
  empty/missing instead of silently marking every node blocked; ASCII-only report
  output; new --strict flag; build the registry lookup once and reuse it.

Docs/tests:
- RELEASE.md: migration note for the lfx 0.5.0 -> 1.10.0 version jump.
- Regression tests for the checker fixes, the shared gate, fail-fast registry,
  --strict, and serve --upgrade-flow parity.

* [autofix.ci] apply automated fixes

* [autofix.ci] apply automated fixes (attempt 2/3)

* fix(lfx): consolidate flow-envelope handling and fix version-ceiling regex

Extract the outer-envelope unwrap/rewrap logic (previously hand-rolled as
raw.get("data", raw) with subtly different rules across serve, run, and
upgrade) into a single lfx.utils.flow_envelope module with split/merge
helpers. This fixes a serve bug where an enveloped flow had its inner graph
written bare to the temp file, making the loader's flow_graph["data"] raise
KeyError.

Also fix release.yml's major.minor extraction: the greedy sed grabbed the
upper bound from a range pin (>=1.10.0,<1.11.dev0), drifting the version
ceiling up one minor each release cycle. Anchor to the first version instead.

* fix(lfx): upgrade-flow gate reads bundled component index, not empty cache

The --upgrade-flow=check|safe gate on lfx run and lfx serve rejected every
flow as 'blocked'. Both call sites passed component_cache.all_types_dict to
apply_upgrade_gate, but that cache is populated lazily after services start,
so at gate time it is empty -- an empty registry classifies every node as
blocked. The standalone lfx upgrade command was unaffected because it reads
the bundled _assets/component_index.json instead.

Make the gate own registry loading: apply_upgrade_gate now defaults
all_types_dict to None and loads the bundled index (the same source lfx
upgrade uses) via a new _load_bundled_registry helper, raising
UpgradeFlowError on a missing/empty index so a broken install fails loudly
instead of silently blocking every component. Both call sites pass mode=
and let the gate load the registry.

Existing gate tests mocked component_cache with a populated registry, which
is exactly what hid the bug; repoint them at the new _load_bundled_registry
seam and add regression tests that do not mock the registry, including an
end-to-end run_flow check against a real clean v1.9.0 starter flow.

3d685dab14 fix: enable agent-lifecycle-toolkit (altk) on Python 3.14 (#13513)
* fix: enable agent-lifecycle-toolkit (altk) on Python 3.14

agent-lifecycle-toolkit 0.10.x dropped its own requires-python <3.14
cap (now >=3.10) and does not depend on OpenDsStar, so the
`python_version < '3.14'` gate on the altk extra is stale.

- Remove the python_version < '3.14' marker from the altk extra in
  langflow-base, keeping the macOS x86_64 platform exclusion.
- Regenerate uv.lock: agent-lifecycle-toolkit resolves on 3.14 and
  coexists with the onnxruntime>=1.26 langflow forces there
  (verified agent-lifecycle-toolkit 0.10.1 + onnxruntime 1.26.0).

OpenDsStar (the separate OpenDsStarAgent component) stays gated: all
its releases still cap requires-python at <3.14 upstream.

* test: correct stale <3.14 comment in ALTK test import guards

The module-level import skips in the ALTK agent tests carried an
outdated comment claiming "agent-lifecycle-toolkit is gated to
python_version<'3.14' upstream". That is no longer accurate:
agent-lifecycle-toolkit 0.10.1 dropped the <3.14 cap (now requires
>=3.10), and this PR removes the langflow <3.14 marker on the altk extra.

The skip itself is preserved -- altk is an optional extra
(langflow-base[altk]) that may be absent from a given environment, so
the ImportError guard is still required. Only the comment is corrected,
to state the real reason for the skip plus the upstream change. Applied
to all four files carrying the identical comment (test_altk_agent,
test_altk_agent_logic, test_altk_agent_tool_conversion,
test_conversation_context_ordering).

Also tag a pre-existing fake test key (api_key="sk-test") with
`# pragma: allowlist secret`; the comment shift re-staged the file and
surfaced it to detect-secrets.

Validated (Python 3.13, altk installed): ruff clean; the three logic
modules run (64 passed, 4 skipped) and test_altk_agent collects (13).

09ae9cf0f2 fix: enable IBM watsonx.ai bundle on Python 3.14 (#13512)
* fix: enable IBM watsonx.ai bundle on Python 3.14

ibm-watsonx-ai (1.5.13) and langchain-ibm (1.1.0) added Python 3.14
support upstream on 2026-06-03, so the official 3.14 Docker image no
longer needs to silently drop the IBM integration.

- Lift the `python_version < '3.14'` markers on ibm-watsonx-ai and
  langchain-ibm in both the lfx-ibm bundle and langflow-base.
- Bump langchain-ibm from `~=1.0.2` to `~=1.1.0`; the 3.14-capable
  release is 1.1.0, which the old `~=1.0.2` pin excluded.
- Regenerate uv.lock: the resolver now forks ibm-watsonx-ai into
  1.5.13 for py>=3.11 (incl. 3.14) and 1.3.42 for py<3.11, so 3.10
  keeps working while 3.14 gains the integration.

watsonx-orchestrate (ibm-watsonx-orchestrate-core/clients) stays gated
at <3.14 since upstream 2.10.0 still caps there.

* test: stop import-skipping IBM watsonx tests on Python 3.14

The watsonx test modules skipped at module load (pytest.skip with
allow_module_level=True) when langchain-ibm / ibm-watsonx-ai failed to
import, with comments tying the skip to the upstream <3.14 cap. Now that
those deps are importable on 3.14 (this PR's dep bump), the import-based
skip can hide real import regressions instead of surfacing them.

- test_model_utils.py, test_watsonx.py, test_watsonx_embeddings.py:
  replace the try/except pytest.skip(allow_module_level=True) guards with
  direct top-level imports so a missing or broken IBM SDK fails loudly.
  Drop the now-unused `import pytest` in test_model_utils.py.
- src/bundles/ibm/README.md: update the platform note to reflect that the
  watsonx components are now importable on Python 3.10-3.14.

The Db2 tests (test_db2*, test_optional_dependency) are left untouched --
they gate on ibm-db's linux/aarch64 platform exclusion, not the Python
version, which is still valid.

Validated locally (Python 3.13): 63 tests pass (13 + 50), ruff clean.

* fix(playground): expand session checkbox click target to full row height

The selectable-row checkbox wrapper was ``w-4 h-4`` (16x16 px) but the
row is ``h-8`` (32 px). The 8 px band above and the 8 px band below
the visible icon were dead zones that bubbled to the row's
``toggleVisibility`` and navigated to the session instead of toggling
selection — exactly the accidental-navigation UX the bug ticket
describes.

Grow the wrapper to ``w-4 h-8`` so the click target captures the full
row height. Width stays narrow so the text alignment is unchanged; the
icon itself stays ``h-4 w-4``, centered via the existing
``flex items-center justify-center``. Visual position is identical.

Adds ``__tests__/session-selector-checkbox-click-target.test.tsx``
(3 cases): wrapper className guard (h-8 + w-4, not h-4), click on the
wrapper outside the icon triggers selection without bubbling to
toggleVisibility, and click on the inner icon still toggles selection.

ec0b11d721 chore: update lock files (#13483)
* chore: update lock files

update lock files

* fix: migrate Mongo/Weaviate/Perplexity components off removed langchain-community classes

langchain-community 0.4.2 (pulled in by the lock update) removed the
MongoDBAtlasVectorSearch and Weaviate vector stores and the ChatPerplexity
chat model. The MongoDB import failed at test collection, aborting both
backend unit-test groups with an ImportError.

Migrate to the standalone packages, all already declared dependencies:
- mongodb: langchain_mongodb.MongoDBAtlasVectorSearch (drop-in)
- perplexity: langchain_perplexity.ChatPerplexity (drop-in)
- weaviate: rewrite for weaviate-client v4 (connect_to_weaviate_cloud /
  connect_to_custom) + langchain_weaviate.WeaviateVectorStore, adding
  advanced gRPC host/port inputs. The component was already broken on
  weaviate-client v4, which removed the v3 weaviate.Client(url=...) API.

Component class names and identifiers are unchanged, so existing flows are
preserved. The component index is left for the autofix CI job to regenerate.

* test: fix concurrent-import deadlock in test_all_modules_importable

test_all_lfx_component_modules_directly_importable imports ~488 modules
concurrently via asyncio.gather over asyncio.to_thread(importlib.import_module).
It flaked ~50% with:

  _DeadlockError: deadlock detected by _ModuleLock('toolguard.runtime.runtime')
  on lfx.components.models_and_agents.policies.tool_invoker

toolguard has an internal circular import: toolguard/runtime/__init__.py does
`from .runtime import ...` while runtime.py does `from toolguard.runtime import
IToolInvoker`. It resolves fine single-threaded, but the lfx policy modules reach
the cycle from two entry points at once -- policies.tool_invoker enters at the
toolguard.runtime package while policies.guard_sync_utils enters at the
toolguard.runtime.runtime submodule. On separate worker threads one holds the
package lock waiting on the submodule lock while the other does the reverse, so
CPython's import machinery raises _DeadlockError.

Pre-import both entry points single-threaded before the fan-out so sys.modules is
warm and the threaded imports only hit the cache. Keeps full parallelism and
coverage (every module is still imported; no skip-list entry).

Verified 24/24 green vs a 4/8 baseline.

The dropdownComponent Playwright test pastes component code into the code editor and clicks "Check & Save", which validates the code by importing it. langchain-community 0.4.2 (this branch's lock bump) removed `langchain_community.chat_models.bedrock`, so the import threw, the code modal stayed open, and enableInspectPanel timed out clicking `canvas_controls_dropdown_help` through the open dialog. Failed deterministically (all retries + GHA re-run), only on this branch.

Swap the fixture to `langchain_aws.ChatBedrock`, matching the real Amazon Bedrock component which already migrated, and upstream guidance (BedrockChat deprecated since lc 0.0.34).

Also move the 0.4.2-removed `langchain_community.chat_models.litellm` import off the top level of the deactivated ChatLiteLLM component into build_model so the module imports cleanly. No loaded/product components affected.

Extension-bundle components have namespaced node ids of the form ext:<bundle>:<ClassName>@<slot>-<uuid>. The flow-build status banner rendered that raw id, which overflowed the fixed-width (530px) container and collided with the elapsed-time counter.

Collapse namespaced ids to <ComponentName>-<uuid> (matching the built-in ComponentName-UUID label) via a new getRunningNodeLabel helper; built-in node ids are returned unchanged. Covered by unit tests.

b95d309c46 fix(tracing): surface Langfuse setup failures, pin pydantic>=2.13 (Py3.14) (#13341)
* fix(tracing): surface Langfuse setup failures and pin pydantic>=2.13 for Py3.14

Docker v1.9.3 silently dropped Langfuse traces because the Docker image
was bumped to Python 3.14 while the lockfile still resolved pydantic
2.12.x. Langfuse v3 imports `pydantic.v1.BaseModel`, which only gained
Python 3.14 support in pydantic 2.13. On the user's Docker container,
`from langfuse import Langfuse` raised `pydantic.v1.errors.ConfigError`,
the broad `except Exception` in `_setup_langfuse` logged at debug level,
and the tracer initialized with `_ready = False` — no error in default
logs, no traces in Langfuse. PyPI installs worked because users tend to
run Python 3.10-3.13 where pydantic.v1 is still happy.

Two changes:

- Replace `logger.debug` with `logger.warning`/`logger.exception` in
  `_setup_langfuse` so future failures (network, auth, dependency
  conflicts) surface in logs by default instead of vanishing silently.
- Add `pydantic>=2.13.0` to the `langfuse` extra in
  `src/backend/base/pyproject.toml` so the Python 3.14 import path is
  guaranteed to work whenever the extra is installed, regardless of
  what other deps resolve transitively.

Adds regression tests asserting `_setup_langfuse` calls
`logger.warning`/`logger.exception` on the three failure modes
(auth check returning False, auth check raising, post-auth setup
exception).

e08080507b feat: Add langflow-stepflow package (#12015)
* feat: Add langflow-stepflow package

Introduces a new workspace package `src/langflow-stepflow/` that ports
the Stepflow integration from the Stepflow repository into the Langflow
codebase.

The package has two submodules:
- `translation/`: translates Langflow flow JSON to Stepflow flow
  definitions (ported from integrations/langflow/converter/)
- `worker/`: a Stepflow worker that executes individual Langflow
  components via lfx (ported from integrations/langflow/executor/)

Entry point: `python -m langflow_stepflow.worker` starts the HTTP worker
server for use by a Stepflow orchestrator.

No changes to existing Langflow code in this commit.

* fix: Address review feedback on langflow-stepflow package

- Widen Python version to >=3.10,<3.14 to match langflow-base
- Fix import sorting (ruff I001) and unused variable (ruff F841)
- Replace sk- prefixed test strings to avoid Gitleaks false positives
- Remove placeholder step reference resolution in component_tool
  (orchestrator resolves these before reaching the worker)
- Let exceptions propagate from component_tool_executor instead of
  returning error dicts that look like successful results
- Skip secret/password field defaults in tool input schemas
- Use LRU-style bounded cache (128) for compiled components
- Use asyncio.to_thread for sync component methods to avoid blocking
- Fix mutable NamedTuple default (list→tuple) in PlaceholderGraph
- Warn and skip deps with missing field mappings instead of silently
  falling back to "input" (which overwrites on multiple deps)
- Tighten _is_data_list to check __class_name__ == "Data" specifically
- Add comment explaining intentional teardown-before-init sequence
- Add integration test for example flows

* chore: Upgrade to Stepflow SDK 0.12.0 and adapt to lfx 0.3+ renames

- Bump stepflow-py and stepflow-orchestrator from >=0.10.0 to >=0.12.0
- Remove Python 3.11 environment markers (SDK now supports 3.10+)
- Replace server.run() with gRPC pull transport (run_grpc_worker)
  matching the upstream stepflow-langflow integration pattern
- Update Flow serialization from Pydantic model_dump to msgspec.to_builtins
- Remove Pydantic ValueExpr/actual_instance unwrapping (now plain dicts)
- Add _langflow_type_name() to map lfx 0.3+ class renames (JSON→Data,
  Table→DataFrame) back to canonical Langflow type names
- Fix DataFrame isinstance checks for lfx Table subclass
- Add missing README.md, tests/__init__.py, helpers package
- Add skip conditions for missing fixture files

* change to lfx schema

* [autofix.ci] apply automated fixes

* [autofix.ci] apply automated fixes

* chore: Align langflow-stepflow ruff config with repo and format

- Run ruff format across all source and test files
- Add pragma: allowlist secret on test fixtures with fake API keys

workspace and the lockfile. Without this, uv sync on Python 3.14
fails the Unit/LFX/Integration test jobs and the Docker build.

cc009c9133 feat(lfx): Bundle Separation and LFX Extension Framework (#13043)
* feat(lfx): installed-package + seed-directory discovery for production install (LE-1022)

Adds the read-only production install path for Modes A, B, and C of the
Bundle Separation iteration. Manifest-shipping pip-installed
distributions and seed-directory subdirectories are discovered at server
startup and registered as Extensions at @official.

* discovery.py: walks importlib.metadata.distributions() + the
  $LANGFLOW_SEED_DIR / /opt/langflow/bundles seed root; produces
  DiscoveredExtension records and typed errors for malformed manifests
  / configured-but-missing seed dirs.
* registry.py: ExtensionRegistry service with the immutability
  invariant for installed and seed entries. Mutation verbs (uninstall,
  disable, enable, install, update_entry) all raise
  ExtensionImmutableError carrying the typed
  installed-extension-immutable / seed-directory-immutable code so the
  invariant is testable today; the CLI uninstall surface ships in B4.
* lfx extension list: read-only inspector with text and JSON output
  for operators inspecting Mode B/C images.
* Errors: four new typed codes
  (installed-extension-immutable, seed-directory-immutable,
  seed-directory-not-found, duplicate-extension-id) plus snapshot
  coverage in tests/unit/extension/test_errors.py.
* Tests: 165 extension tests pass, including the LE-1022 acceptance
  cases -- three pip-installed wheels visible at @official, three seed
  bundles visible at @official, and the parametrized service-layer
  immutability check across every mutation verb.
* Docs: docs/Deployment/deployment-extensions-production.mdx covers
  the Dockerfile template, k8s deployment notes, the bundle packaging
  convention (extension.json shipped via package-data), and
  troubleshooting for the typed error codes.

* feat(lfx): add single-Bundle loader and LANGFLOW_COMPONENTS_PATH discovery (#12967)

* feat(lfx): add extension manifest schema, validate CLI, and error formatter (LE-1014)

Foundation for the Bundle Separation iteration. Defines what a valid
extension.json looks like (Pydantic models + Draft 2020-12 JSON Schema),
ships the offline `lfx extension validate` command, and ships the single
`format_extension_error` function that every other extension-system module
will use to render structured errors.

What's in lfx.extension:

- `ExtensionManifest` / `BundleRef` / `LangflowCompat` Pydantic models with
  `extra="forbid"` so unknown fields fail loudly. Deferred fields (`services`,
  `routes`, `hooks`, `starter_projects`, `userConfig`) are reserved as
  None-only so non-null values produce a dedicated
  `field-deferred-in-this-milestone` error instead of a generic schema wall.
  `bundles` accepts a list but rejects length > 1 with
  `multi-bundle-deferred-in-this-milestone` (validator-enforced; the loader
  re-checks at install time in LE-1015).
- `schema.build_schema()` + `build_schema_json()` produce the publishable
  artifact at schemas.langflow.org/extension/v1.json.
- `ExtensionError` typed envelope and `format_extension_error` -- one branch
  per discriminant. Codes are registered in `ERROR_CODES`; an
  `ExtensionError` constructed with an unknown code raises at construction
  time, preventing producers from shipping without a matching renderer.
- `validate_extension` runs four passes: manifest discovery + schema,
  path-safety (no `..`, no absolute paths, no symlink escape), AST
  inspection of every `.py` (syntax, Component subclass present, build()
  declared, top-level `import *`, top-level I/O primitives), and an opt-in
  `--execute-imports` that runs each module in a subprocess with a
  temporary HOME / TMPDIR / LANGFLOW_CONFIG_DIR and LANGFLOW_*/LFX_* env
  vars stripped.
- `lfx extension validate` and `lfx extension schema` typer subcommands.

Acceptance-criteria coverage in tests/unit/extension/:

- Round-trips every v0 manifest field; deferred fields rejected; multi-bundle
  rejected with the dedicated discriminant.
- JSON Schema validates the v0 example and rejects 12 malformed manifests
  with distinct error paths (>= 10 required by the ticket).
- Median default-validate runtime < 100ms on the basic template.
- Crafted side-effect bundle: default validate does NOT execute it (canary
  file is never written); `--execute-imports` DOES execute it and the canary
  appears, while LANGFLOW_* env vars are NOT inherited by the subprocess.
- Snapshot tests for every code in ERROR_CODES; a guard test verifies
  ERROR_CODES and the snapshot table are in lockstep so future additions
  cannot ship without a format branch and a snapshot.

Wiring: `lfx extension` is a sub-app under the Authoring help panel so
future tickets (LE-1016 init/dev, LE-1018 reload) can attach without
colliding with the existing `lfx validate` (which validates flow JSON, not
extensions).

* fix(lfx): fall back to tomli on Python 3.10 in extension manifest loader

tomllib is stdlib only on 3.11+, but lfx supports 3.10-3.13. Use the
existing tomli runtime dependency as the 3.10 fallback (same API, so the
import alias keeps the rest of the module unchanged).

Fixes ModuleNotFoundError seen in CI on the 3.10 job.

* feat(lfx): add single-Bundle loader and LANGFLOW_COMPONENTS_PATH discovery (LE-1015)

Introduces lfx.extension.loader: the runtime that turns an Extension on disk
into LoadedComponent records keyed by ext:<bundle>:<Class>@<slot>. Two paths in:

  - load_extension(root): one manifest, one Bundle, registered at @official.
    Re-checks multi-bundle at runtime (defense-in-depth vs. the schema).
  - discover_inline_bundles(paths): each subfolder of LANGFLOW_COMPONENTS_PATH
    is a Bundle at @extra. Walk order is platform-independent (sorted dirs,
    user-declared path order). First-wins on duplicate names; second emits
    duplicate-inline-bundle warning that names both paths.

Manifest-first precedence helpers (installed_extension_roots,
manifest_owning_distributions, filter_plugin_entry_points) let callers of
the legacy langflow.plugins entry-point loader skip distributions that ship
a manifest, so component entry-points are not double-registered.

New typed error codes: module-import-failed, duplicate-component-name,
duplicate-distribution, duplicate-inline-bundle, inline-bundle-name-invalid.
Each ships with a format branch and a snapshot test.

Tests cover the AC: single-bundle happy path, multi-bundle rejection,
missing/empty/no-Component bundle, duplicate class names, deterministic
walk order, recursive discovery, inline-bundle first-wins + dot-dir skip
+ bundle.json metadata, manifest-first precedence partition, PEP-503
distribution-name canonicalization.

* fix(lfx): address LE-1015 review feedback

- Drop the unproduced duplicate-distribution error code; LE-1022 will add
  it once startup-time discovery has a place to surface it.  Restores the
  invariant that every code in ERROR_CODES has a producer.
- Clarify that intra-bundle relative imports are NOT supported in v0; only
  absolute references between bundle modules work in this milestone.
- Use strict=False when re-resolving bundle_root in the walker; the path
  was already existence-checked, and a concurrent removal in the narrow
  window should not raise across the loader's public boundary.
- Hoist the json import out of _read_inline_bundle_json's body.

* refactor(lfx): split extension loader into a small subpackage (LE-1015)

Addresses the file-size feedback from the LE-1015 review.  The single
870-line loader.py becomes a flat package keyed off the four section
banners that already existed inline:

    loader/
      __init__.py     # re-exports the public surface
      _types.py       # SLOT constants, LoadedComponent, LoadResult
      _discovery.py   # filesystem walk + importlib.util orchestration
      _detection.py   # Component subclass identification (MRO heuristic)
      _orchestrator.py # load_extension, discover_inline_bundles
      _plugins.py     # manifest-first precedence over langflow.plugins

Largest file is now _orchestrator.py at 440 LOC (was 870); every file is
well under the 800-LOC project guideline.  No behavior change: the public
import paths from lfx.extension are unchanged, all 38 loader tests still
pass.  ``_canonicalize_distribution`` is now exported as
``canonicalize_distribution`` from ``loader._plugins`` (it's a stable
PEP-503 helper that downstream modules will reach for, so it loses the
private underscore).

The test suite is split to mirror the package:

    tests/unit/extension/loader/
      conftest.py             # shared fixtures, FakeDist, autouse scrub
      test_load_extension.py  # @official slot, identity, failure modes
      test_inline_bundles.py  # LANGFLOW_COMPONENTS_PATH, @extra slot
      test_plugins.py         # manifest-first precedence helpers
      test_types.py           # LoadedComponent, LoadResult, code parity

Each test file imports its own slice of the public API and pulls fixtures
from conftest, so a reader looking at one banner can read it in isolation.

and failed at the manifest layer. Update conftest.py + test_load_extension.py
to the post-rename API.

Strip 17 LE-XXXX ticket references from loader source files, errors.py
loader-specific comments, and the four loader test docstrings, matching the
convention applied to LE-1014. Descriptive prose preserved.

Promote _BUNDLE_NAME_RE to BUNDLE_NAME_RE on the manifest module so the
loader's orchestrator no longer reaches across modules into a private name.

* refactor(lfx): clarify broad except, log malformed bundle.json, expand test docstring

- Document why _discovery.import_bundle_module catches BaseException (startup-time loader, must surface bad bundles as typed errors rather than abort).
- Add debug-level logging when bundle.json is malformed or non-object so a stale-cache footgun is at least observable.
- Expand test_skips_re_imported_class docstring so future maintainers don't accidentally weaken the __module__-equality guard if package-style relative imports get added later.

Also drops the stale duplicate-distribution claim from the PR description; that code is correctly deferred to LE-1022 along with /all integration.

* feat(lfx): wire Extension System into /all, pathsep-split LANGFLOW_COMPONENTS_PATH, emit duplicate-distribution

Closes the four AC gaps the previous reviewer flagged on PR #12967:

1. /all integration: get_and_cache_all_types_dict now also calls a new
   import_extension_components() that loads installed Extensions via
   load_installed_extensions, loads inline bundles via discover_inline_bundles,
   and builds frontend-node templates with extension/bundle/extension_version
   fields stamped on. Failures are logged and skipped per bundle.

2. LANGFLOW_COMPONENTS_PATH is now split on os.pathsep so multi-entry env vars
   (e.g. /a:/b on POSIX) produce multiple components-path entries instead of
   one literal non-existent path. Empty segments and missing paths are skipped.

3. duplicate-distribution is a real producer: load_installed_extensions
   surfaces a typed warning on the winner LoadResult when two distributions
   share a canonical name, naming every involved manifest path.

4. Manifest-first precedence runtime wiring: new filter_component_entry_points
   loads each entry-point and only skips ones that resolve to a Component
   subclass on a manifest-shipping distribution. plugin_routes.load_plugin_routes
   now applies it so non-component entry-points (route registrars) keep
   loading per the AC's 'unaffected' promise. Added the previously-missing
   AC test for same-distribution component+non-component partition.

Also makes _distribution_canonical_name defensive against MagicMock test seams.

* fix(lfx): register extension components under namespaced ID; promote duplicate-distribution to error

Addresses the latest review of PR #12967:

P1: /all integration now keys the cache inner dict by LoadedComponent.namespaced_id
(ext:<bundle>:<Class>@<slot>) rather than the bare class name. Templates also carry
the namespaced_id as an explicit field so consumers that look at the value (not the
key) still see the canonical address. This is the form the LE-1020 migration table
will rewrite legacy class-name references to.

P2: load_installed_extensions now appends duplicate-distribution to result.errors
instead of result.warnings, so LoadResult.ok=False when two distributions share a
canonical name. The winner's components still appear in result.components so flows
already pinned to them keep working; only the conflict status changes. Updated test
to assert errors + ok=False; added explicit assertion that the winner's components
are still present.

* fix(lfx): installed-distribution discovery accepts pyproject.toml manifest form

Closes the latest review finding on PR #12967: the installed-distribution
scan only looked for extension.json, ignoring distributions whose manifest
lives in [tool.langflow.extension] inside pyproject.toml. The AC explicitly
treats both as valid manifest forms.

_distribution_manifest_path now:
- Returns extension.json immediately when present (preserves precedence
  matching load_manifest's discovery order).
- Falls back to pyproject.toml only when extension.json is absent AND the
  pyproject's [tool.langflow.extension] section is parseable.

Validation reuses load_manifest itself so the rule lives in exactly one
place; a stray pyproject.toml without the section is correctly ignored.

Tests cover: pyproject-only discovery, pyproject-without-section ignored,
extension.json wins on collision, end-to-end pyproject load at @official,
and pyproject-form manifest-first entry-point suppression.

* refactor(lfx): tighten loader invariants, surface silent skips, harden tests

Addresses the latest review feedback on PR #12967:

Type-level invariants (_types.py):
- LoadedComponent.__post_init__ enforces that @extra components must NOT
  carry a distribution. The reverse (@official without distribution) is
  permitted because load_extension is also used for dev-mode loads
  against a working tree before pip install.
- LoadResult docstring documents the partial-success contract: components
  may be non-empty when errors is non-empty (some files imported, others
  failed). Callers branching on ok get strict success.

Silent-failure fixes (_orchestrator.py + settings/base.py):
- inline-path-missing: a non-existent / non-dir LANGFLOW_COMPONENTS_PATH
  entry now produces a typed warning per skipped path so a typo no
  longer yields zero diagnostics. Settings-layer skip bumped from debug
  to warning for the same reason.
- bundle-json-invalid: a malformed or non-object bundle.json now surfaces
  a typed warning instead of silently rewriting the user-declared
  id/version to derived values under the same bundle name.
- no-component-subclass gating uses a call-local counter instead of
  result.errors so the diagnostic stays accurate when a future caller
  reuses a LoadResult (multi-bundle / batch wrapper scenarios).

Test hardening:
- test_re_imported_class_is_skipped_via_module_filter rewritten to
  actually exercise the __module__-equality check via sys.modules
  injection; previously passed via module-import-failed (relative-import
  failure), which would silently weaken if package registration changes.
- test_user_declared_path_order_is_preserved: AC #8's multi-path order
  case (distinct bundles in [path_b, path_a]) was unasserted; added.
- test_inline_module_import_failure_attributes_identity: AC #10's
  identity-on-partial-failure was covered for @official but not @extra;
  added.
- test_uses_real_distributions_by_default tightened to assert ep
  placement (in kept, not in skipped) instead of exact-list equality, so
  a future Langflow-shipped manifest doesn't silently flip the assertion.

bumped 64 -> 175 passing extension tests; 20 backend integration tests
still pass.

* fix(lfx): malformed pyproject manifests surface manifest-invalid instead of disappearing

Closes the latest review finding on PR #12967: a pyproject.toml with a
[tool.langflow.extension] section that has missing/invalid required
fields was silently dropped because _pyproject_has_extension_section
ran full schema validation via load_manifest and returned False on
ValueError/TypeError. That conflated 'no section' with 'section
malformed'.

Fix: detect section presence only. _pyproject_has_extension_section now
calls _read_pyproject_extension (TOML parse + key lookup, no schema
check). Behavior:
- Section absent or pyproject TOML unparseable -> False (treat as
  regular non-manifest package).
- Section present and is a table (valid OR schema-invalid) -> True.
- Section present but is not a table -> True; the author intended to
  declare an extension and load_extension will surface the typed error.

This way a typo'd pyproject Extension produces a typed manifest-invalid
LoadResult with extension_id attribution, and manifest-first precedence
still suppresses its legacy component entry-points -- matching the
'typed load results on success/failure' contract for the supported
pyproject manifest form.

Tests: two new cases pin the behavior. test_malformed_pyproject_section_
surfaces_manifest_invalid asserts a typed load-failure result with
distribution attribution; the second test pins manifest-first
suppression for malformed pyproject distributions.

* refactor(lfx): emit inline-path-unreadable, document reload contract, trim rot

Closes the remaining nits on PR #12967:

- inline-path-unreadable (new typed error code): a configured
  LANGFLOW_COMPONENTS_PATH entry that raises OSError on iterdir
  (typically permission-denied) now produces a typed LoadResult error
  carrying str(exc) instead of silently swallowing the message.
- duplicate-inline-bundle hint trimmed: removed forward promise about
  hard-error-in-a-later-release; same actionability, no expiration.
- discover_inline_bundles docstring trimmed from three paragraphs to
  two sentences (per CLAUDE.md anti-multi-paragraph rule).
- _distribution_manifest_path docstring trimmed to one-liner.
- installed_extension_roots dropped Used-by caller-narration list;
  manifest_owning_distributions docstring rewritten to call out the
  shadow-load risk for direct callers and point to load_installed_
  extensions for the typed warning surface.
- _discovery.import_bundle_module: replaced 'until that lands in a
  later milestone' rot with a single line ('Absolute imports only
  between bundle modules; relative imports unsupported.') AND added
  the single-load-per-process contract note documenting why LE-1018
  reload must scrub registry/sys.modules before re-invoking the loader.
- load_extension docstring grew a 'Single-load-per-process contract'
  block telling direct callers not to rely on this function for refresh.

Tests: new test_unreadable_path_emits_inline_path_unreadable pins the
OSError -> typed-error path.

* feat(lfx): atomic-swap Bundle reload pipeline + endpoint + CLI (LE-1018) (#12979)

* feat(lfx): add single-Bundle loader and LANGFLOW_COMPONENTS_PATH discovery (LE-1015)

Introduces lfx.extension.loader: the runtime that turns an Extension on disk
into LoadedComponent records keyed by ext:<bundle>:<Class>@<slot>. Two paths in:

  - load_extension(root): one manifest, one Bundle, registered at @official.
    Re-checks multi-bundle at runtime (defense-in-depth vs. the schema).
  - discover_inline_bundles(paths): each subfolder of LANGFLOW_COMPONENTS_PATH
    is a Bundle at @extra. Walk order is platform-independent (sorted dirs,
    user-declared path order). First-wins on duplicate names; second emits
    duplicate-inline-bundle warning that names both paths.

Manifest-first precedence helpers (installed_extension_roots,
manifest_owning_distributions, filter_plugin_entry_points) let callers of
the legacy langflow.plugins entry-point loader skip distributions that ship
a manifest, so component entry-points are not double-registered.

New typed error codes: module-import-failed, duplicate-component-name,
duplicate-distribution, duplicate-inline-bundle, inline-bundle-name-invalid.
Each ships with a format branch and a snapshot test.

Tests cover the AC: single-bundle happy path, multi-bundle rejection,
missing/empty/no-Component bundle, duplicate class names, deterministic
walk order, recursive discovery, inline-bundle first-wins + dot-dir skip
+ bundle.json metadata, manifest-first precedence partition, PEP-503
distribution-name canonicalization.

* fix(lfx): address LE-1015 review feedback

- Drop the unproduced duplicate-distribution error code; LE-1022 will add
  it once startup-time discovery has a place to surface it.  Restores the
  invariant that every code in ERROR_CODES has a producer.
- Clarify that intra-bundle relative imports are NOT supported in v0; only
  absolute references between bundle modules work in this milestone.
- Use strict=False when re-resolving bundle_root in the walker; the path
  was already existence-checked, and a concurrent removal in the narrow
  window should not raise across the loader's public boundary.
- Hoist the json import out of _read_inline_bundle_json's body.

* refactor(lfx): split extension loader into a small subpackage (LE-1015)

Addresses the file-size feedback from the LE-1015 review.  The single
870-line loader.py becomes a flat package keyed off the four section
banners that already existed inline:

    loader/
      __init__.py     # re-exports the public surface
      _types.py       # SLOT constants, LoadedComponent, LoadResult
      _discovery.py   # filesystem walk + importlib.util orchestration
      _detection.py   # Component subclass identification (MRO heuristic)
      _orchestrator.py # load_extension, discover_inline_bundles
      _plugins.py     # manifest-first precedence over langflow.plugins

Largest file is now _orchestrator.py at 440 LOC (was 870); every file is
well under the 800-LOC project guideline.  No behavior change: the public
import paths from lfx.extension are unchanged, all 38 loader tests still
pass.  ``_canonicalize_distribution`` is now exported as
``canonicalize_distribution`` from ``loader._plugins`` (it's a stable
PEP-503 helper that downstream modules will reach for, so it loses the
private underscore).

The test suite is split to mirror the package:

    tests/unit/extension/loader/
      conftest.py             # shared fixtures, FakeDist, autouse scrub
      test_load_extension.py  # @official slot, identity, failure modes
      test_inline_bundles.py  # LANGFLOW_COMPONENTS_PATH, @extra slot
      test_plugins.py         # manifest-first precedence helpers
      test_types.py           # LoadedComponent, LoadResult, code parity

Each test file imports its own slice of the public API and pulls fixtures
from conftest, so a reader looking at one banner can read it in isolation.

* feat(lfx): atomic-swap Bundle reload pipeline + endpoint + CLI (LE-1018)

Five-stage reload (parallel staging load -> validate -> swap under write
lock -> cleanup -> emit) for installed Bundles in Mode A.  In-flight
flows keep the pre-swap class via existing references; new flows pick up
the post-swap class atomically; concurrent reloads on the same Bundle
are rejected with reload-in-progress.

Adds:

* lfx/extension/registry.py -- BundleRegistry with per-bundle
  reload-in-progress guard and components_index.json writer
* lfx/extension/reload.py -- the five-stage pipeline; events emission
  is stubbed (TODO LE-1017) so the swap mechanics can ship before the
  events service lands
* loader: optional module_namespace param so Stage 1 lands in
  __reload_staging__.<id> instead of the live _lfx_ext.* namespace
* errors: four new typed reload codes (reload-in-progress,
  reload-bundle-not-installed, reload-bundle-name-mismatch,
  reload-source-missing) with branch templates and snapshot tests
* HTTP: POST /api/v1/extensions/{id}/bundles/{name}/reload, gated by
  the existing get_current_active_user dependency, returns 409 with a
  typed body for the in-progress collision case
* CLI: lfx extension reload <id> [--bundle <name>] -- HTTP client
  against the dev server with text/json output and proper exit codes
  (--all is gated until LE-1019 lands the list endpoint)
* tests: 16 reload-pipeline tests covering the AC matrix (rename
  round-trip, broken-bundle isolation, concurrent readers, in-flight
  flow, double-reload guard, bundle-name mismatch) plus 9 CLI client
  tests

Mode A only.  In Mode B/C bundle changes require a Docker image rebuild
and the reload path is not exercised.

The events emission in Stage 5 is intentionally stubbed -- the LE-1017
ticket will swap the body of _emit_bundle_reload_event in one place
without touching the pipeline core.

* [autofix.ci] apply automated fixes

* feat(lfx): add `extension init` and `extension dev` CLIs (LE-1016) (#12968)

* feat(lfx): add extension manifest schema, validate CLI, and error formatter (LE-1014)

Foundation for the Bundle Separation iteration. Defines what a valid
extension.json looks like (Pydantic models + Draft 2020-12 JSON Schema),
ships the offline `lfx extension validate` command, and ships the single
`format_extension_error` function that every other extension-system module
will use to render structured errors.

What's in lfx.extension:

- `ExtensionManifest` / `BundleRef` / `LangflowCompat` Pydantic models with
  `extra="forbid"` so unknown fields fail loudly. Deferred fields (`services`,
  `routes`, `hooks`, `starter_projects`, `userConfig`) are reserved as
  None-only so non-null values produce a dedicated
  `field-deferred-in-this-milestone` error instead of a generic schema wall.
  `bundles` accepts a list but rejects length > 1 with
  `multi-bundle-deferred-in-this-milestone` (validator-enforced; the loader
  re-checks at install time in LE-1015).
- `schema.build_schema()` + `build_schema_json()` produce the publishable
  artifact at schemas.langflow.org/extension/v1.json.
- `ExtensionError` typed envelope and `format_extension_error` -- one branch
  per discriminant. Codes are registered in `ERROR_CODES`; an
  `ExtensionError` constructed with an unknown code raises at construction
  time, preventing producers from shipping without a matching renderer.
- `validate_extension` runs four passes: manifest discovery + schema,
  path-safety (no `..`, no absolute paths, no symlink escape), AST
  inspection of every `.py` (syntax, Component subclass present, build()
  declared, top-level `import *`, top-level I/O primitives), and an opt-in
  `--execute-imports` that runs each module in a subprocess with a
  temporary HOME / TMPDIR / LANGFLOW_CONFIG_DIR and LANGFLOW_*/LFX_* env
  vars stripped.
- `lfx extension validate` and `lfx extension schema` typer subcommands.

Acceptance-criteria coverage in tests/unit/extension/:

- Round-trips every v0 manifest field; deferred fields rejected; multi-bundle
  rejected with the dedicated discriminant.
- JSON Schema validates the v0 example and rejects 12 malformed manifests
  with distinct error paths (>= 10 required by the ticket).
- Median default-validate runtime < 100ms on the basic template.
- Crafted side-effect bundle: default validate does NOT execute it (canary
  file is never written); `--execute-imports` DOES execute it and the canary
  appears, while LANGFLOW_* env vars are NOT inherited by the subprocess.
- Snapshot tests for every code in ERROR_CODES; a guard test verifies
  ERROR_CODES and the snapshot table are in lockstep so future additions
  cannot ship without a format branch and a snapshot.

Wiring: `lfx extension` is a sub-app under the Authoring help panel so
future tickets (LE-1016 init/dev, LE-1018 reload) can attach without
colliding with the existing `lfx validate` (which validates flow JSON, not
extensions).

* fix(lfx): fall back to tomli on Python 3.10 in extension manifest loader

tomllib is stdlib only on 3.11+, but lfx supports 3.10-3.13. Use the
existing tomli runtime dependency as the 3.10 fallback (same API, so the
import alias keeps the rest of the module unchanged).

Fixes ModuleNotFoundError seen in CI on the 3.10 job.

* feat(lfx): add `extension init` and `extension dev` CLIs (LE-1016)

The two scaffolding CLIs an Extension author types:

  - `lfx extension init <target>` writes the basic single-Bundle
    template (manifest with $schema, README, .gitignore, one Component
    subclass + a pytest smoke test).  AC #1: the generated extension
    validates clean against LE-1014.  AC #2: the generated test file is
    a valid pytest module that exercises the component's build() method.
    AC #3: any --template other than 'basic' fails with a typed
    template-deferred-in-this-milestone error and a non-zero exit.
    Refuses to scaffold over a non-empty target dir.

  - `lfx extension dev <target>` validates the local extension, records
    its absolute path in <config_dir>/extensions/dev_extensions.json,
    prints reload instructions, and execs `langflow run` (or
    `python -m langflow` when langflow isn't on PATH).  --skip-launch
    registers without launching (used by tests + external dev-server
    scripts); --skip-validate lets authors register a known-broken
    manifest to debug it under the loader.

Stack:
  - Wave 0: error codes (extension-target-exists,
    extension-target-invalid, local-extension-missing) with format
    branches and snapshot tests.
  - Wave 1: lfx.extension.init_template -- pure-data scaffolder, no
    Typer dependency so the CLI is a thin shell over it.
  - Wave 1: lfx.extension.dev_registry -- atomic JSON state file under
    the langflow user-cache dir; helpers for register / list /
    unregister / load_dev_extensions / dev_extension_component_paths.
  - Wave 2: lfx.cli._extension_commands gains init/dev subcommands.
  - Wave 2: langflow.main lifespan hook reads the dev registry after
    bundle loading and extends components_path with each registered
    bundle dir, so the existing palette discovery picks up dev
    extensions.  Missing paths surface as local-extension-missing
    warnings (AC #5) without aborting startup.

Tests (84 new, 197 total in tests/unit/extension/):
  - test_init_template.py: AC scenarios + identifier derivation +
    deterministic file shape.
  - test_dev_registry.py: register/list/unregister round-trip,
    idempotent re-register refreshes timestamp, malformed state file
    treated as empty, missing-path warning, recovery when path
    reappears, env-var override precedence.
  - test_cli.py: AC #1 init->validate, AC #3 deferred templates,
    --skip-launch registers without launching, --skip-validate
    short-circuits the pre-flight pass.
  - test_errors.py: snapshot rows for all three new codes; the
    every-known-code-has-a-snapshot test enforces parity.

LE-1018 (reload) reuses load_dev_extensions; LE-1022 (installed-pkg
discovery) shares the components_path extension pattern.  AC #4 ("boots
Langflow with the extension visible in the palette within 5s") is
delivered jointly by `extension dev` (registers + execs) and the
lifespan hook (loads on startup).

* fix(lfx): address LE-1016 review feedback

Fixes the four HIGH issues + the elevated LOW from the review pass:

1. dev_extension_component_paths now forwards EVERY warning, not just
   local-extension-missing.  Previously a duplicate-component-name (or
   any future warning code) was silently dropped, hiding real signal
   from the lifespan hook's logs.

2. Defensive emit when a LoadResult has components but source_path is
   None.  The current loader always sets source_path, but a future
   hand-built LoadResult could violate that contract; we now surface a
   typed local-extension-missing error rather than dropping the
   extension silently.

3. Replaced the fragile ``min(len(parts))`` bundle-root selection with
   a relative-to-source-path measurement.  Handles deep-vs-shallow
   sibling extensions correctly without depending on absolute path
   depth.

4. Generated README now documents the langflow/lfx prerequisite under
   the Develop section so authors know `pytest` requires the lfx
   environment, not just Python.

5. Forced LANGFLOW_LAZY_LOAD_COMPONENTS=false unconditionally in the
   `extension dev` exec env (was setdefault, which let a developer's
   global lazy-loading export silently hide their dev components from
   the palette and miss AC #4's 5s budget).

Plus three MEDIUMs:

  - sys.modules cleanup in test_generated_test_file_runs_against_generated_component
    so a later test importing the same dotted path doesn't pick up a
    stale module from a deleted tmp_path.  Component instantiation
    moved inside the try block because Component.__init__ uses
    inspect.getsourcefile against self.__class__'s still-live module.
  - Added regex-drift test that pins the init_template patterns to
    match manifest.py's so a schema regex change can't quietly produce
    invalid scaffolded manifests.
  - Added two new dev_registry tests covering the forward-all-warnings
    contract and the source_path=None defense.

Tests: 201 passing (4 new); ruff check + format clean.

* fix: LangflowCompat -> LfxCompat

* fix: Remove references to ticket

* fix: encode maxItems constraint in schema

* fix: deferred fields and schema version

* Fix ruff errors

* fix: align loader tests with renamed manifest API and strip ticket refs

The merge of feat/extension-validate brought in the LfxCompat / compat
rename, but the loader test fixtures still used LangflowCompat / bundle_api
and failed at the manifest layer. Update conftest.py + test_load_extension.py
to the post-rename API.

Strip 17 LE-XXXX ticket references from loader source files, errors.py
loader-specific comments, and the four loader test docstrings, matching the
convention applied to LE-1014. Descriptive prose preserved.

Promote _BUNDLE_NAME_RE to BUNDLE_NAME_RE on the manifest module so the
loader's orchestrator no longer reaches across modules into a private name.

* fix(lfx): align init template with renamed manifest API

After merging feat/extension-loader into this branch, two surfaces
fell out of sync with the renamed manifest schema:

- init_template generates extension.json with `lfx: {bundle_api: [1]}`,
  but the validator now requires `lfx: {compat: ["1"]}` per LfxCompat.
  This made `test_basic_template_validates_clean` fail with
  manifest-invalid (`lfx.compat: Field required; lfx.bundle_api: Extra
  inputs are not permitted`).
- test_init_template_regexes_match_manifest_schema reads
  `manifest_mod._BUNDLE_NAME_RE`, but that symbol was promoted to public
  `BUNDLE_NAME_RE` in c63f84a591. Update the test to reference the
  public name; init_template's local copy is still private since it
  also covers `_EXTENSION_ID_RE`, which remains private upstream.

* feat(lfx): append-only migration table + flow deserializer rewrite hook (#13024)

* feat(lfx): add extension manifest schema, validate CLI, and error formatter (LE-1014)

Foundation for the Bundle Separation iteration. Defines what a valid
extension.json looks like (Pydantic models + Draft 2020-12 JSON Schema),
ships the offline `lfx extension validate` command, and ships the single
`format_extension_error` function that every other extension-system module
will use to render structured errors.

What's in lfx.extension:

- `ExtensionManifest` / `BundleRef` / `LangflowCompat` Pydantic models with
  `extra="forbid"` so unknown fields fail loudly. Deferred fields (`services`,
  `routes`, `hooks`, `starter_projects`, `userConfig`) are reserved as
  None-only so non-null values produce a dedicated
  `field-deferred-in-this-milestone` error instead of a generic schema wall.
  `bundles` accepts a list but rejects length > 1 with
  `multi-bundle-deferred-in-this-milestone` (validator-enforced; the loader
  re-checks at install time in LE-1015).
- `schema.build_schema()` + `build_schema_json()` produce the publishable
  artifact at schemas.langflow.org/extension/v1.json.
- `ExtensionError` typed envelope and `format_extension_error` -- one branch
  per discriminant. Codes are registered in `ERROR_CODES`; an
  `ExtensionError` constructed with an unknown code raises at construction
  time, preventing producers from shipping without a matching renderer.
- `validate_extension` runs four passes: manifest discovery + schema,
  path-safety (no `..`, no absolute paths, no symlink escape), AST
  inspection of every `.py` (syntax, Component subclass present, build()
  declared, top-level `import *`, top-level I/O primitives), and an opt-in
  `--execute-imports` that runs each module in a subprocess with a
  temporary HOME / TMPDIR / LANGFLOW_CONFIG_DIR and LANGFLOW_*/LFX_* env
  vars stripped.
- `lfx extension validate` and `lfx extension schema` typer subcommands.

Acceptance-criteria coverage in tests/unit/extension/:

- Round-trips every v0 manifest field; deferred fields rejected; multi-bundle
  rejected with the dedicated discriminant.
- JSON Schema validates the v0 example and rejects 12 malformed manifests
  with distinct error paths (>= 10 required by the ticket).
- Median default-validate runtime < 100ms on the basic template.
- Crafted side-effect bundle: default validate does NOT execute it (canary
  file is never written); `--execute-imports` DOES execute it and the canary
  appears, while LANGFLOW_* env vars are NOT inherited by the subprocess.
- Snapshot tests for every code in ERROR_CODES; a guard test verifies
  ERROR_CODES and the snapshot table are in lockstep so future additions
  cannot ship without a format branch and a snapshot.

Wiring: `lfx extension` is a sub-app under the Authoring help panel so
future tickets (LE-1016 init/dev, LE-1018 reload) can attach without
colliding with the existing `lfx validate` (which validates flow JSON, not
extensions).

* fix(lfx): fall back to tomli on Python 3.10 in extension manifest loader

tomllib is stdlib only on 3.11+, but lfx supports 3.10-3.13. Use the
existing tomli runtime dependency as the 3.10 fallback (same API, so the
import alias keeps the rest of the module unchanged).

Fixes ModuleNotFoundError seen in CI on the 3.10 job.

* feat(lfx): add single-Bundle loader and LANGFLOW_COMPONENTS_PATH discovery (LE-1015)

Introduces lfx.extension.loader: the runtime that turns an Extension on disk
into LoadedComponent records keyed by ext:<bundle>:<Class>@<slot>. Two paths in:

  - load_extension(root): one manifest, one Bundle, registered at @official.
    Re-checks multi-bundle at runtime (defense-in-depth vs. the schema).
  - discover_inline_bundles(paths): each subfolder of LANGFLOW_COMPONENTS_PATH
    is a Bundle at @extra. Walk order is platform-independent (sorted dirs,
    user-declared path order). First-wins on duplicate names; second emits
    duplicate-inline-bundle warning that names both paths.

Manifest-first precedence helpers (installed_extension_roots,
manifest_owning_distributions, filter_plugin_entry_points) let callers of
the legacy langflow.plugins entry-point loader skip distributions that ship
a manifest, so component entry-points are not double-registered.

New typed error codes: module-import-failed, duplicate-component-name,
duplicate-distribution, duplicate-inline-bundle, inline-bundle-name-invalid.
Each ships with a format branch and a snapshot test.

Tests cover the AC: single-bundle happy path, multi-bundle rejection,
missing/empty/no-Component bundle, duplicate class names, deterministic
walk order, recursive discovery, inline-bundle first-wins + dot-dir skip
+ bundle.json metadata, manifest-first precedence partition, PEP-503
distribution-name canonicalization.

* fix(lfx): address LE-1015 review feedback

- Drop the unproduced duplicate-distribution error code; LE-1022 will add
  it once startup-time discovery has a place to surface it.  Restores the
  invariant that every code in ERROR_CODES has a producer.
- Clarify that intra-bundle relative imports are NOT supported in v0; only
  absolute references between bundle modules work in this milestone.
- Use strict=False when re-resolving bundle_root in the walker; the path
  was already existence-checked, and a concurrent removal in the narrow
  window should not raise across the loader's public boundary.
- Hoist the json import out of _read_inline_bundle_json's body.

* refactor(lfx): split extension loader into a small subpackage (LE-1015)

Addresses the file-size feedback from the LE-1015 review.  The single
870-line loader.py becomes a flat package keyed off the four section
banners that already existed inline:

    loader/
      __init__.py     # re-exports the public surface
      _types.py       # SLOT constants, LoadedComponent, LoadResult
      _discovery.py   # filesystem walk + importlib.util orchestration
      _detection.py   # Component subclass identification (MRO heuristic)
      _orchestrator.py # load_extension, discover_inline_bundles
      _plugins.py     # manifest-first precedence over langflow.plugins

Largest file is now _orchestrator.py at 440 LOC (was 870); every file is
well under the 800-LOC project guideline.  No behavior change: the public
import paths from lfx.extension are unchanged, all 38 loader tests still
pass.  ``_canonicalize_distribution`` is now exported as
``canonicalize_distribution`` from ``loader._plugins`` (it's a stable
PEP-503 helper that downstream modules will reach for, so it loses the
private underscore).

The test suite is split to mirror the package:

    tests/unit/extension/loader/
      conftest.py             # shared fixtures, FakeDist, autouse scrub
      test_load_extension.py  # @official slot, identity, failure modes
      test_inline_bundles.py  # LANGFLOW_COMPONENTS_PATH, @extra slot
      test_plugins.py         # manifest-first precedence helpers
      test_types.py           # LoadedComponent, LoadResult, code parity

Each test file imports its own slice of the public API and pulls fixtures
from conftest, so a reader looking at one banner can read it in isolation.

loader's orchestrator no longer reaches across modules into a private name.

* feat(lfx): append-only migration table + flow deserializer rewrite hook

Adds the migration layer of the Extension System: an append-only JSON table
that maps three legacy component reference shapes (bare class name, old
import path, pre-Phase-A namespaced slot) to the post-Phase-A canonical
ext:<bundle>:<Class>@<slot> identifier, plus a deserializer hook that
rewrites a saved-flow payload in place against that table on load.

What landed:

  * lfx.extension.migration.schema -- Pydantic models for MigrationEntry +
    MigrationTable with per-entry validators (exactly one of bare/import/slot
    populated; canonical target shape) and table-level uniqueness check.
  * lfx.extension.migration.loader -- canonical in-repo path, threadsafe
    process-lifetime cache, typed errors on every failure mode.
  * lfx.extension.migration.rewrite -- node-by-node rewrite, idempotent on
    canonical refs, difflib-backed closest-match suggestion for unmapped
    references, cross-bucket ambiguity surfaces component-name-ambiguous
    instead of silently loading into the wrong bundle.
  * Wired into Graph.from_payload before validate_flow_for_current_settings
    so every saved-flow load goes through migration first.
  * scripts/migrate/check_migration_append_only.py -- CI guard that diffs
    the working-tree table against origin/main and rejects removals or
    target mutations; reordering and additions are allowed.
  * 34 new unit tests covering rewrite paths, loader failure modes, schema
    invariants, and the CI script behavior.

What is deliberately deferred:

  * flow-migrated event emission. The events pipeline is unavailable in this
    iteration; the wiring point in Graph.from_payload is marked TODO and the
    MigrationReport already carries every field a future emitter needs.

The shipped migration_table.json starts empty; entries land alongside the
pilot bundle extraction in a follow-up.

* feat(lfx): atomic-swap Bundle reload pipeline + endpoint + CLI (LE-1018)

Five-stage reload (parallel staging load -> validate -> swap under write
lock -> cleanup -> emit) for installed Bundles in Mode A.  In-flight
flows keep the pre-swap class via existing references; new flows pick up
the post-swap class atomically; concurrent reloads on the same Bundle
are rejected with reload-in-progress.

Adds:

* lfx/extension/registry.py -- BundleRegistry with per-bundle
  reload-in-progress guard and components_index.json writer
* lfx/extension/reload.py -- the five-stage pipeline; events emission
  is stubbed (TODO LE-1017) so the swap mechanics can ship before the
  events service lands
* loader: optional module_namespace param so Stage 1 lands in
  __reload_staging__.<id> instead of the live _lfx_ext.* namespace
* errors: four new typed reload codes (reload-in-progress,
  reload-bundle-not-installed, reload-bundle-name-mismatch,
  reload-source-missing) with branch templates and snapshot tests
* HTTP: POST /api/v1/extensions/{id}/bundles/{name}/reload, gated by
  the existing get_current_active_user dependency, returns 409 with a
  typed body for the in-progress collision case
* CLI: lfx extension reload <id> [--bundle <name>] -- HTTP client
  against the dev server with text/json output and proper exit codes
  (--all is gated until LE-1019 lands the list endpoint)
* tests: 16 reload-pipeline tests covering the AC matrix (rename
  round-trip, broken-bundle isolation, concurrent readers, in-flight
  flow, double-reload guard, bundle-name mismatch) plus 9 CLI client
  tests

Mode A only.  In Mode B/C bundle changes require a Docker image rebuild
and the reload path is not exercised.

The events emission in Stage 5 is intentionally stubbed -- the LE-1017
ticket will swap the body of _emit_bundle_reload_event in one place
without touching the pipeline core.

* feat(frontend): palette Bundle reload action + loading + toasts

Adds the frontend half of the bundle reload flow.  When the Bundle
header is right-clicked or its overflow ("⋮") icon clicked, a Reload
action fires POST /api/v1/extensions/{id}/bundles/{name}/reload and
surfaces the result via the existing alert-store toast system.

What landed (frontend only):

  * src/controllers/API/queries/extensions/ -- typed wire-format models
    (ReloadBundleResponse, ExtensionErrorPayload, ReloadInProgressDetail)
    and the useReloadBundle mutation hook.  The hook unwraps the 409
    `reload-in-progress` detail into a stable, parseable Error message so
    the UI can branch without reading status codes.
  * components/bundleHeaderActions.tsx -- new Select-based overflow menu
    next to the Bundle header chevron.  Three toast paths: success
    (green, with components +/- delta), structural failure (red, with
    typed errors and inline hints), reload-in-progress (notice).
    Loading state swaps the kebab icon for a spinning Loader2 while
    the request is in flight.  Renders nothing when no extension_id is
    on the bundle, so the static SIDEBAR_BUNDLES list is unaffected.
  * components/bundleItems.tsx -- wires the new actions in next to the
    chevron, plus a context-menu (right-click) capture that opens the
    same overflow trigger so keyboard / mouse / right-click all share
    one source of truth.
  * types/index.ts -- BundleItemProps.item gains an optional
    extension_id; took the opportunity to extract the SidebarBundle
    interface and tighten three pre-existing `any` types.
  * customization/feature-flags.ts -- ENABLE_EXTENSION_RELOAD gate, off
    by default until the bundle-list endpoint that populates extension_id
    per bundle ships.
  * controllers/API/helpers/constants.ts -- EXTENSIONS URL constant.
  * Tests: 7 component tests + 3 mutation-hook tests, all green.  Total
    sidebar + extensions test count: 479 passing.

Deferred:

  * Event-pipeline subscription is left as an inline TODO.  The mutation
    response carries enough information to drive the toasts on its own
    today; once the events service lands the toast wiring will move to
    a `bundle_reloaded` / `bundle_reload_failed` listener so multi-tab
    and multi-worker swaps surface exactly once.

* feat: End to end bundle installation

* fix: Review comments addressed

* Update component_index.json

* Update component_index.json

* Update router.py

* fix(docker): copy src/bundles before uv sync so workspace bundles resolve

Each directory under ``src/bundles`` is a uv workspace member referenced by
``langflow-base`` (and the root project) as a path dependency.  The Docker
builders ran ``uv sync --no-install-project`` after copying only the
top-level pyproject.toml files, so resolution failed with
``Distribution not found at: file:///app/src/bundles/<name>``.

Copying the whole ``src/bundles`` tree (rather than enumerating each
bundle) means a new bundle dropped under that dir does not require a
Dockerfile edit.  The full ``./src`` copy a few lines later produces the
same final layer either way; this earlier copy just unblocks the
dependency-resolution sync.

Touched all builders that run a workspace-resolving uv sync:

  * docker/build_and_push.Dockerfile
  * docker/build_and_push_base.Dockerfile
  * docker/build_and_push_ep.Dockerfile
  * docker/build_and_push_with_extras.Dockerfile
  * docker/dev.Dockerfile (bind-mount instead of COPY)

- test_path_override_bypasses_cache: mirror the cached canonical table
  into the temp file instead of asserting it's empty.  Drift in
  migration_table.json (the duckduckgo entries shipped with the B1
  pilot) no longer breaks the cache-bypass invariant.

- test_lfx_duckduckgo_ships_manifest: editable installs (pip install -e)
  surface only dist-info entries in dist.files, so we cannot use that
  path to find extension.json in the workspace venv.  Detect editable
  mode via direct_url.json's PEP 660 marker and fall through to walking
  the source tree; non-editable wheel installs still exercise the
  dist.files path the loader uses at runtime.

Each directory under ``src/bundles`` is a uv workspace member referenced by

``Distribution not found at: file:///app/src/bundles/<name>``.

Copying the whole ``src/bundles`` tree (rather than enumerating each
bundle) means a new bundle dropped under that dir does not require a
Dockerfile edit.  The full ``./src`` copy a few lines later produces the
same final layer either way; this earlier copy just unblocks the
dependency-resolution sync.

Touched all builders that run a workspace-resolving uv sync:

  * docker/build_and_push.Dockerfile
  * docker/build_and_push_base.Dockerfile
  * docker/build_and_push_ep.Dockerfile
  * docker/build_and_push_with_extras.Dockerfile
  * docker/dev.Dockerfile (bind-mount instead of COPY)

* fix: Review sweep

* fix: More review comments addressed

* Ruff check

* docs: add bundle porting guide

Step-by-step recipe for extracting a provider package from the in-tree
``src/lfx/src/lfx/components/<provider>/`` directory into a standalone
Extension Bundle distribution under ``src/bundles/<provider>/``.

The DuckDuckGo bundle is the reference; every section maps to a single
copy-pasteable change and a verification command.

Doc surfaces a forthcoming ``scripts/migrate/port_bundle.py`` automation
helper for the mechanical bits; that script lands on the next branch
together with the second-pilot port that validates the recipe end-to-end.

* fix(extension): accept Output(method=...) in build-method validator

The validator's static AST check looked for a literal ``build`` method
on every Component subclass and emitted ``build-method-missing`` when
absent.  Real Langflow components -- including the production
``DuckDuckGoSearchComponent`` and the in-tree ``ArXivComponent`` -- do
not declare a literal ``build``; they declare entry-points
declaratively via ``outputs = [Output(name=..., method=<name>)]`` and
the named method is what gets called.  Result: every clean port hit a
spurious ``build-method-missing`` error from ``lfx extension validate``.

Fix: extend ``_has_build_method`` to also accept any class that names a
method via ``Output(method="X")`` AND defines that method in the class
body.  The negative case ("Output(method=...) without a matching def")
still fires -- a typo'd method name would crash at runtime, so the
static check should keep flagging it.

Two new tests in ``test_validate.py`` lock the contract: positive case
mirroring duckduckgo / arxiv, negative case for typo'd method names.
All 26 validator tests pass.

PORTING.md updates fall out of running the recipe live against the
duckduckgo bundle on this branch:

  * Validate path is ``src/bundles/<bundle>/src/lfx_<bundle>``, not the
    bundle root (the manifest lives next to ``__init__.py``).
  * Index regen needs ``LFX_DEV=1`` to skip the prebuilt-index fast path
    and uses ``scripts/build_component_index.py``.
  * Drop the migration-table JSON from the ruff invocation (ruff treats
    it as Python and complains about the top-level expression).

* fix: Delete outdated components

* fix(palette): wire reload kebab via DropdownMenu, not Select

The reload kebab on the palette Bundle header was using Radix ``Select``
to back its overflow menu.  ``Select`` is for picking a value, not for
firing an action: ``onValueChange`` is gated by value-equality (so a
re-click of the only item is a no-op), and the popover-portal click
semantics interact poorly with the parent disclosure-trigger button.
The combined effect: clicking ⋮ → Reload opened the popover and closed
it, but never fired the network request, with no console error to point
at.

Switch to ``DropdownMenu`` (purpose-built action menu).
``DropdownMenuItem`` exposes ``onSelect`` which fires on every
activation -- the same callback path keyboard navigation uses -- so
clicking Reload reliably invokes the mutation.

Test mocks updated to drive the DropdownMenu primitives instead of
Select; all 8 bundleHeaderActions tests + the broader 437-test sidebar
suite still pass.

* fix(extension): route ddgs through the lockfile + drop bogus list endpoint hint

Two reviewer findings, both about reproducibility / correctness of
operator-facing surfaces.

[P2] ``docker/build_and_push_base.Dockerfile`` previously installed
``ddgs`` via an unpinned ``uv pip install ddgs`` after the workspace
sync.  That made the base image non-reproducible: a future ``ddgs``
release would silently drift from the tested lock state on every
rebuild.

Fix: route ddgs through the locked sync.

  * Restore the ``duckduckgo`` extra in ``src/backend/base/pyproject.toml``
    (``ddgs>=9.0.0``) as an internal "image-build sidecar".  Public
    consumers still install ``lfx-duckduckgo`` directly; the extra
    exists only to keep ``ddgs`` resolved in the lockfile.
  * The Dockerfile now passes ``--extra duckduckgo`` to ``uv sync
    --frozen``, picking up the locked ``ddgs==9.14.1``.
  * The follow-on bundle install keeps ``--no-deps`` so it does not
    duplicate the now-locked ``ddgs`` / ``lfx`` / ``langchain-community``.

[P3] ``langflow/api/v1/extensions.py`` returned a fix hint that pointed
operators at ``GET /api/v1/extensions`` -- a route that does not exist
in this PR (it lands with the LE-1019 list endpoint).  Replaced with a
reference to ``lfx extension list``, which is shipped here.

* fix(compat): bridge langflow.components.* dynamically via meta path finder

Commit 45552cd1df ("fix: Delete outdated components") removed the
physical shim files under ``src/backend/base/langflow/components/``
that forwarded saved-flow imports like
``from langflow.components.processing.converter import convert_to_dataframe``
or ``import langflow.components.knowledge_bases.retrieval`` to their
new ``lfx.components.*`` homes.  Without those shims, dotted imports
into ``langflow.components.<sub>.<leaf>`` failed at flow-load time --
the existing ``LangflowCompatibilityModule`` registers ``langflow.components``
itself in ``sys.modules`` but does not bridge submodules, so Python's
import machinery falls through to the now-empty langflow.components
directory and raises ``ModuleNotFoundError``.

Replace the deleted physical-shim stack with a single ``MetaPathFinder``
in ``langflow/__init__.py`` that dynamically resolves every
``langflow.components.<rest>`` import to ``lfx.components.<rest>`` and
registers the loaded lfx module in ``sys.modules`` under both names.
The langflow- and lfx-prefixed imports share a single underlying module
object, so class identity is preserved across the bridge -- ``isinstance``
checks against types resolved through either path keep working.

The finder also carries a small first-segment override map for the few
subpackages whose name diverged during the move; the only entry today is
``knowledge_bases`` -> ``files_and_knowledge``, matching the deleted
shim's intent.

Why a meta finder instead of restoring the physical shim files (option
1 from the scope analysis): the meta finder scales without per-bundle
maintenance.  Every future bundle extraction landed under ``lfx.components``
becomes reachable via the legacy ``langflow.components.<bundle>`` path
immediately; nobody has to remember to add a parallel langflow shim.

Six new unit tests in ``test_langflow_components_compat_shim.py`` lock
the contract: dotted submodule resolution, helpers re-export, the
``knowledge_bases`` override, class identity preservation, top-level
aliasing, and the "arbitrary extracted bundle" case that prevents
regression for future ports.

Verified pre-existing tests:
  * 17 dynamic-import integration tests pass.
  * The reload-route-guard suite still passes.
  * The Research Translation Loop starter-project test (which loads
    ArXivComponent) passes.

* Update index.tsx

* fix: Review pass on delivery

* fix: Second review sweep, bare names

* fix: Third review sweep

* Resolve dotted imports and attribute chains

Record import shape and flatten attribute chains so router references can be resolved across dotted imports and re-exports. Added ImportTarget dataclass, _attribute_chain helper, and switched IncludeCall/DecoratorRef to store attribute tuples. parse_file now records ImportTarget entries for imports and captures dotted parent/child chains for include_router and decorators. Replaced _resolve_var with _resolve_chain which handles "from" vs "module" imports, various import shapes (including import x.y and aliased imports), and prevents infinite recursion on re-export cycles.

* One more sweep

* Add seed-directory extension loading and docs

Introduce filesystem "seed directory" extension support and authoring docs. Adds three documentation pages (quickstart, manifest reference, author guide) and wires them into the docs sidebar. Implement load_seed_extensions to discover/load bundles from $LANGFLOW_SEED_DIR (default /opt/langflow/bundles), export it from loader/__init__ and extension package, and integrate it into the components import pipeline. Handle installed-vs-seed shadowing by preferring installed distributions and appending a typed seed-bundle-shadowed ExtensionError; add the corresponding error code and message. Update schema doc link and add unit/integration tests to cover seed loading, determinism, shadowing behavior, and migration-target resolution.

* fix: pytest testpaths glob and accurate scaffold output in port_bundle

testpaths now uses ``src/bundles/*/tests`` so future bundle tests are
picked up automatically without hardcoding each bundle at the root.
pytest expands the glob via ``glob.iglob(..., recursive=True)``.

Rewrote port_bundle.py's ``_render_migration_entries`` and
``_render_test_scaffold`` to match the actual conventions:

* Migration entries now use ``bare_class_name``/``import_path``/
  ``legacy_slot`` + ``target`` + ``added_in`` (the keys
  ``lfx.extension.migration.loader`` actually reads) instead of the
  invented ``from``/``to``/``release`` shape.
* Test scaffold now imports ``load_migration_table`` and
  ``migrate_flow_payload`` -- the APIs the real tests use -- instead of
  a fictitious ``resolve_legacy_id``.  Includes the ``migration_table``
  fixture, ``_saved_flow``/``_saved_flow_node`` helpers, and the
  distribution-importable + manifest-shipped checks that mirror
  ``test_pilot_duckduckgo_upgrade.py``.

Verified by rendering the scaffold for duckduckgo with synthetic plan
data, dropping it into ``src/lfx/tests/integration/extension/``, and
running pytest -- ``3 passed, 2 skipped`` (skips are the wheel-only
checks, by design when run inside the lfx isolation venv).

* feat: Port Arxiv to the Extension Framework (#13047)

* feat(bundles): port arxiv as the second-pilot Bundle + porting helper

Validates ``src/bundles/PORTING.md`` end-to-end by following its recipe
against a clean candidate (``ArXivComponent``: no third-party runtime
deps, no langflow-base extra, no deactivated duplicate).  Touchpoints
exercised:

  * Bundle skeleton at ``src/bundles/arxiv/`` mirroring duckduckgo.
  * In-tree provider directory removed from ``src/lfx/src/lfx/components/``
    along with its three references in ``components/__init__.py``.
  * Workspace wiring: dep, ``[tool.uv.sources]``, ``[tool.uv.workspace]``
    members, lockfile.
  * Migration table: bare-name + two import-path forms + legacy_slot
    entry.
  * Component index regenerated via ``LFX_DEV=1`` (forces dynamic
    discovery; without it the script reproduces stale entries).
  * Integration test ``test_pilot_arxiv_upgrade.py`` mirroring the
    duckduckgo pilot suite; 5 tests pass against the workspace install.

PORTING.md updates fall out of running the recipe live:
  * Validate path is ``src/bundles/<bundle>/src/lfx_<bundle>``, not the
    bundle root (the manifest lives next to ``__init__.py``).
  * Index regen needs ``LFX_DEV=1`` to skip the prebuilt-index fast path.
  * Drop the migration-table JSON from the ruff invocation (ruff treats
    it as Python and complains about the top-level expression).

``scripts/migrate/port_bundle.py`` is the mechanical helper referenced
from § Automation: stdlib-only, dry-run by default, refuses on invalid
input, and intentionally leaves migration-table edits + integration-test
authoring to a human (release version + bare-name uniqueness require
judgement).  Three guard rails verified: invalid bundle name,
existing-target-bundle, missing in-tree provider.

* fix: resolve cross-source bundle-name shadowing before registry population

The reload pipeline reads ``live.source_path`` from the registry on every
call.  Previously, the registry-population loop in
``import_extension_components`` only special-cased installed-shadows-seed;
for every other pair (seed/dev, seed/inline, dev/inline,
installed/dev, installed/inline) it silently overwrote earlier records
via last-wins iteration order.  A stale dev registration whose
``source_path`` pointed at a different filesystem location could clobber
the seed record's ``source_path``; reload would then walk the dev path
while the operator edited the seed copy on disk -- producing 200 OK with
empty deltas on every reload, including for syntactically broken edits.

Generalize the dedup pass to every (earlier, later) pair using the
explicit precedence ``installed > seed > dev > inline``, applied before
both registry population AND palette template construction so the two
read from the same winning source.  Add a new generic ``bundle-shadowed``
typed error code for the pairs the existing ``seed-bundle-shadowed`` did
not cover; keep ``seed-bundle-shadowed`` for the documented installed-
over-seed pair so existing CLI exit-code logic and snapshot tests stay
intact.  Both codes are warn-only in ``lfx extension list``.

Also add an INFO log line in reload Stage 1 with the resolved
``source_path`` so the next "200 OK with empty deltas" repro can be
triaged from the server log alone -- if the path logged is not the path
the operator was editing, this dedup is what to look at.

Includes a regression test
(``test_seed_bundle_shadows_dev_emits_generic_bundle_shadowed``) that
asserts both halves: seed wins in the BundleRegistry AND the registry's
``source_path`` is the seed path, not the stale dev path.

* Update component_index.json

* fix: widen lfx-* bundles' requires-python to <3.15 to match langflow root

The two pilot bundles (``lfx-arxiv``, ``lfx-duckduckgo``) were scaffolded
by ``scripts/migrate/port_bundle.py`` whose template hard-coded
``requires-python = ">=3.10,<3.14"``.  Because both bundles are uv
workspace members of the langflow root, that cap leaked into every
workspace-level resolve: ``cd src/lfx && uv sync`` (the path
``make lfx_tests`` takes) refuses to pick a Python 3.14 interpreter even
though lfx itself, langflow, and langflow-base all advertise
``>=3.10,<3.15``.  Hosts with 3.14 installed see:

    error: The requested interpreter resolved to Python 3.14.5, which
    is incompatible with the project's Python requirement: `>=3.10, <3.14`.

Fix at the source so future ``port_bundle.py`` runs do not regress this:
template emits ``<3.15``, and the two existing emitted pyprojects are
bumped in lockstep.  ``uv.lock`` regenerates with the wider range.

Verified ``make lfx_tests`` resolves cleanly on a host with both 3.13.12
and 3.14.5 installed; the focused extension slice runs to completion.

a80cf1c649 chore: support Python 3.14 (#13085)
* feat: upgrade Docker images to Python 3.14 (experimental)

- Update pyproject.toml: requires-python from <3.14 to <3.15
- Update all 5 Dockerfiles to use Python 3.14:
  - Builder stage: python3.12-trixie-slim → python3.14-trixie-slim
  - Runtime stage: python:3.12-slim-trixie → python:3.14-slim-trixie

- src/backend/base/pyproject.toml
- docker/build_and_push_base.Dockerfile
- docker/build_and_push.Dockerfile
- docker/build_and_push_backend.Dockerfile
- docker/build_and_push_with_extras.Dockerfile
- docker/build_and_push_ep.Dockerfile

Python 3.14.5 was released on May 10, 2026. Upgrading to the latest
Python version should help reduce CVE vulnerabilities in Docker images.

This is an experimental change to test Python 3.14 compatibility:
- Docker images will use Python 3.14
- CI/CD workflows still test on Python 3.10-3.13
- Nightly build will validate if dependencies work with 3.14
- Can be reverted quickly if issues are found

- Monitor nightly build for failures
- If successful, update CI/CD workflows to add Python 3.14 to test matrix
- If failures occur, revert and investigate compatibility issues

* chore: support Python 3.14

Bump requires-python upper bound to <3.15 across langflow, langflow-base,
lfx, and langflow-sdk, and add 3.14 to CI test matrices so PRs are gated
on 3.14 compatibility.

Conditional pins for transitive deps without 3.14 wheels at the existing
caps:
- onnxruntime: >=1.26 on 3.14 (existing <1.24 cap retained for 3.10)
- faiss-cpu: >=1.13.2 on 3.14 (existing ==1.9.0.post1 retained for <3.14)

* chore: marker-gate IBM watsonx packages for Python 3.14

ibm-watsonx-ai 1.3.x cannot import on Python 3.14: its StrEnum subclasses
override __init__ in a way that conflicts with 3.14's reworked enum
__set_name__ path (TypeError on KnowledgeBaseFieldRole class creation).

Cap ibm-watsonx-ai, langchain-ibm, and the ibm-watsonx-orchestrate-*
extras at python_version<'3.14' until upstream adapts. Watsonx component
imports are already lazy, so this surfaces only at component-access time
on 3.14, where the existing ImportError handler in
lfx.components.ibm.__init__ degrades it gracefully.

test_model_utils.py imports ChatWatsonx at module top to verify
get_model_name resolves model_id; guard that import so the test
module skips on 3.14 instead of breaking collection.

* [autofix.ci] apply automated fixes

* chore: upgrade remaining Docker images to Python 3.14

build_and_push*.Dockerfile already moved to 3.14 in the merge from
feat/upgrade-python-3.14-docker-images. Apply the same bump to the
dev, devcontainer, and lfx Docker images so all in-repo Dockerfiles
share one Python version.

* [autofix.ci] apply automated fixes

* chore: gate 3.14-broken extras to python_version<'3.14'

cuga (and its transitive fastembed -> py-rust-stemmers source build),
altk/agent-lifecycle-toolkit (re-pulls ibm-watsonx-ai which was already
gated), langchain-pinecone, langwatch, ragstack-ai-knowledge-store, and
OpenDsStar all pin themselves below 3.14 upstream. Without a marker
guard, the workspace lock still tries to install them and a Docker
`uv sync` then attempts source builds that require Rust (CI Docker
test failure with py-rust-stemmers 0.1.5).

Add python_version<'3.14' (or <'3.13' for ragstack) to each pin so
those packages are simply omitted from the 3.14 install set until
upstream catches up. uv pip check is now clean on 3.14.2.

* test: skip test_altk_agent on Python 3.14

altk (agent-lifecycle-toolkit) is gated to python_version<'3.14'
upstream and now via the langflow-base [altk] extra marker. The test
imports altk at module top to exercise ALTKAgentComponent; guard the
import so collection skips on 3.14 instead of failing.

* test: skip remaining altk tests on Python 3.14

Three more test modules import lfx.base.agents.altk_* at module top,
which transitively imports altk. Add the same module-level skip guard
as test_altk_agent.py:
- test_altk_agent_logic.py
- test_altk_agent_tool_conversion.py
- test_conversation_context_ordering.py

* fix(calculator): replace removed ast.Num with ast.Constant for Python 3.14

ast.Num was deprecated in Python 3.8 in favor of ast.Constant and
removed entirely in 3.14. The calculator tool and its core walker
crashed on 3.14 with 'module ast has no attribute Num'.

Switch the isinstance checks to ast.Constant + isinstance(node.value,
(int, float)), and drop the now-dead ast.Num backwards-compat branch
in calculator_core.py (the ast.Constant branch already handles every
input it would have matched). Update the parser unit-test fixtures
to construct ast.Constant nodes.

* [autofix.ci] apply automated fixes

* [autofix.ci] apply automated fixes (attempt 2/3)

* test: skip LangWatch HTTP instrumentation tests on Python 3.14

langwatch is gated to python_version<'3.14' upstream. The
TestLangWatchHttpInstrumentation class patches langwatch.setup and
langwatch.trace inside a fixture, which requires langwatch to be
importable; on 3.14 the test errors with ModuleNotFoundError.

Guard the class with a skipif on langwatch availability.

* test: allow IBM and altk components to be missing on Python 3.14

test_all_modules_importable enforces that every component in __all__
imports cleanly. On 3.14 the ibm-watsonx-ai, langchain-ibm, and altk
packages are gated upstream and intentionally not installed, so the
WatsonxAI, WatsonxEmbeddings, and ALTKAgent components fail to import
as designed.

- test_all_components_in_categories_importable: accept a known-gated
  deny-list on 3.14 instead of failing.
- test_all_lfx_component_modules_directly_importable: extend the
  existing 'missing optional dependency' allowlist with altk,
  langchain_ibm, and ibm_watsonx_ai.

* fix(lfx): pass ensure_exists to user_cache_dir for Python 3.14

Python 3.14 tightened PurePath.__init__ to reject unknown keyword
arguments. The KeyedWorkerLockManager constructor was passing
ensure_exists=True to Path() instead of user_cache_dir(), which
silently worked on 3.10-3.13 but raises TypeError on 3.14 and also
meant the cache directory was never actually being created.

Move the kwarg to user_cache_dir() where it belongs and update the
two unit tests that asserted the buggy call shape.

* [autofix.ci] apply automated fixes

* test: accept either ZIP or JSON error path on Python 3.14

Python 3.14's zipfile.is_zipfile() now validates the central-directory
signature in addition to EOCD, so the garbage+EOCD payload no longer
passes the is_zipfile() dispatch in the /flows/upload/ route. The
endpoint still returns 400 with a descriptive detail (now from the JSON
branch); only the message wording differs, which the test was asserting
verbatim.

* fix(lfx): normalize cors_origins ['*'] back to '*' on Python 3.14

Pydantic-settings on Python 3.14 parses the env var '*' into ['*']
before the cors_origins field validator runs (the list[str] | str union
resolves differently than on 3.10-3.13). Collapse that back to the
bare-string wildcard so downstream consumers — including
warn_about_future_cors_changes and the test suite — see the same shape
on every supported Python version.

1955f8fae5 chore: support Python 3.14 (#13085)
* feat: upgrade Docker images to Python 3.14 (experimental)

## Changes
- Update pyproject.toml: requires-python from <3.14 to <3.15
- Update all 5 Dockerfiles to use Python 3.14:
  - Builder stage: python3.12-trixie-slim → python3.14-trixie-slim
  - Runtime stage: python:3.12-slim-trixie → python:3.14-slim-trixie

## Files Updated
- src/backend/base/pyproject.toml
- docker/build_and_push_base.Dockerfile
- docker/build_and_push.Dockerfile
- docker/build_and_push_backend.Dockerfile
- docker/build_and_push_with_extras.Dockerfile
- docker/build_and_push_ep.Dockerfile

## Rationale
Python 3.14.5 was released on May 10, 2026. Upgrading to the latest
Python version should help reduce CVE vulnerabilities in Docker images.

## Testing Strategy
This is an experimental change to test Python 3.14 compatibility:
- Docker images will use Python 3.14
- CI/CD workflows still test on Python 3.10-3.13
- Nightly build will validate if dependencies work with 3.14
- Can be reverted quickly if issues are found

## Next Steps
- Monitor nightly build for failures
- If successful, update CI/CD workflows to add Python 3.14 to test matrix
- If failures occur, revert and investigate compatibility issues

* chore: support Python 3.14

Bump requires-python upper bound to <3.15 across langflow, langflow-base,
lfx, and langflow-sdk, and add 3.14 to CI test matrices so PRs are gated
on 3.14 compatibility.

Conditional pins for transitive deps without 3.14 wheels at the existing
caps:
- onnxruntime: >=1.26 on 3.14 (existing <1.24 cap retained for 3.10)
- faiss-cpu: >=1.13.2 on 3.14 (existing ==1.9.0.post1 retained for <3.14)

* chore: marker-gate IBM watsonx packages for Python 3.14

ibm-watsonx-ai 1.3.x cannot import on Python 3.14: its StrEnum subclasses
override __init__ in a way that conflicts with 3.14's reworked enum
__set_name__ path (TypeError on KnowledgeBaseFieldRole class creation).

Cap ibm-watsonx-ai, langchain-ibm, and the ibm-watsonx-orchestrate-*
extras at python_version<'3.14' until upstream adapts. Watsonx component
imports are already lazy, so this surfaces only at component-access time
on 3.14, where the existing ImportError handler in
lfx.components.ibm.__init__ degrades it gracefully.

test_model_utils.py imports ChatWatsonx at module top to verify
get_model_name resolves model_id; guard that import so the test
module skips on 3.14 instead of breaking collection.

* [autofix.ci] apply automated fixes

* chore: upgrade remaining Docker images to Python 3.14

build_and_push*.Dockerfile already moved to 3.14 in the merge from
feat/upgrade-python-3.14-docker-images. Apply the same bump to the
dev, devcontainer, and lfx Docker images so all in-repo Dockerfiles
share one Python version.

* [autofix.ci] apply automated fixes

* chore: gate 3.14-broken extras to python_version<'3.14'

cuga (and its transitive fastembed -> py-rust-stemmers source build),
altk/agent-lifecycle-toolkit (re-pulls ibm-watsonx-ai which was already
gated), langchain-pinecone, langwatch, ragstack-ai-knowledge-store, and
OpenDsStar all pin themselves below 3.14 upstream. Without a marker
guard, the workspace lock still tries to install them and a Docker
`uv sync` then attempts source builds that require Rust (CI Docker
test failure with py-rust-stemmers 0.1.5).

Add python_version<'3.14' (or <'3.13' for ragstack) to each pin so
those packages are simply omitted from the 3.14 install set until
upstream catches up. uv pip check is now clean on 3.14.2.

* test: skip test_altk_agent on Python 3.14

altk (agent-lifecycle-toolkit) is gated to python_version<'3.14'
upstream and now via the langflow-base [altk] extra marker. The test
imports altk at module top to exercise ALTKAgentComponent; guard the
import so collection skips on 3.14 instead of failing.

* test: skip remaining altk tests on Python 3.14

Three more test modules import lfx.base.agents.altk_* at module top,
which transitively imports altk. Add the same module-level skip guard
as test_altk_agent.py:
- test_altk_agent_logic.py
- test_altk_agent_tool_conversion.py
- test_conversation_context_ordering.py

* fix(calculator): replace removed ast.Num with ast.Constant for Python 3.14

ast.Num was deprecated in Python 3.8 in favor of ast.Constant and
removed entirely in 3.14. The calculator tool and its core walker
crashed on 3.14 with 'module ast has no attribute Num'.

Switch the isinstance checks to ast.Constant + isinstance(node.value,
(int, float)), and drop the now-dead ast.Num backwards-compat branch
in calculator_core.py (the ast.Constant branch already handles every
input it would have matched). Update the parser unit-test fixtures
to construct ast.Constant nodes.

* [autofix.ci] apply automated fixes

* [autofix.ci] apply automated fixes (attempt 2/3)

* test: skip LangWatch HTTP instrumentation tests on Python 3.14

langwatch is gated to python_version<'3.14' upstream. The
TestLangWatchHttpInstrumentation class patches langwatch.setup and
langwatch.trace inside a fixture, which requires langwatch to be
importable; on 3.14 the test errors with ModuleNotFoundError.

Guard the class with a skipif on langwatch availability.

* test: allow IBM and altk components to be missing on Python 3.14

test_all_modules_importable enforces that every component in __all__
imports cleanly. On 3.14 the ibm-watsonx-ai, langchain-ibm, and altk
packages are gated upstream and intentionally not installed, so the
WatsonxAI, WatsonxEmbeddings, and ALTKAgent components fail to import
as designed.

- test_all_components_in_categories_importable: accept a known-gated
  deny-list on 3.14 instead of failing.
- test_all_lfx_component_modules_directly_importable: extend the
  existing 'missing optional dependency' allowlist with altk,
  langchain_ibm, and ibm_watsonx_ai.

* fix(lfx): pass ensure_exists to user_cache_dir for Python 3.14

Python 3.14 tightened PurePath.__init__ to reject unknown keyword
arguments. The KeyedWorkerLockManager constructor was passing
ensure_exists=True to Path() instead of user_cache_dir(), which
silently worked on 3.10-3.13 but raises TypeError on 3.14 and also
meant the cache directory was never actually being created.

Move the kwarg to user_cache_dir() where it belongs and update the
two unit tests that asserted the buggy call shape.

* [autofix.ci] apply automated fixes

* test: accept either ZIP or JSON error path on Python 3.14

Python 3.14's zipfile.is_zipfile() now validates the central-directory
signature in addition to EOCD, so the garbage+EOCD payload no longer
passes the is_zipfile() dispatch in the /flows/upload/ route. The
endpoint still returns 400 with a descriptive detail (now from the JSON
branch); only the message wording differs, which the test was asserting
verbatim.

* fix(lfx): normalize cors_origins ['*'] back to '*' on Python 3.14

Pydantic-settings on Python 3.14 parses the env var '*' into ['*']
before the cors_origins field validator runs (the list[str] | str union
resolves differently than on 3.10-3.13). Collapse that back to the
bare-string wildcard so downstream consumers — including
warn_about_future_cors_changes and the test suite — see the same shape
on every supported Python version.

ea29bcc6b9 feat: Redis-backed job queue for multi-worker deployments (#12588)
* feat: implement Redis job queue and fakeredis support
- Refactored the job queue service to support Redis-backed management for cross-worker scaling.
- Added environment variables for configuration:
    - `LANGFLOW_JOB_QUEUE_TYPE=redis`
    - `LANGFLOW_REDIS_QUEUE_DB=1`
- Updated job ownership methods to be asynchronous for improved concurrency handling.
- Enhanced Redis cache service with namespacing via key prefixes.
- Introduced `fakeredis` for in-memory Redis simulation in testin>
- Added comprehensive unit tests for Redis job queue components.

* fix: run  experimental warning for RedisCache usage only once

- Introduced a mechanism to emit a one-time warning for the RedisCache experimental feature during server runtime.
- The warning is logged only if no other worker has already emitted it, ensuring clarity for users regarding the experimental status of RedisCache.
- The implementation includes a temporary file check to prevent multiple warnings across different processes.

* docs: document environment variables for worker management
- Added documentation for LANGFLOW_GUNICORN_PRELOAD to explain preloading for better performance.
- Detailed the use of LANGFLOW_JOB_QUEUE_TYPE for specifying backends (e.g., Redis).
- Included LANGFLOW_REDIS_QUEUE_DB to define the database index for job queues.
- Updated the "High-Load Environments" guide with these optimal configurations.

* docs: updated 'High-load and multi-worker environments' section

* feat: enhance RedisJobQueueService with consumer wrapper management
- Introduced a caching mechanism for Redis stream consumers to optimize job data retrieval.
- Added methods to manage consumer wrappers, ensuring they are reused across sequential polls.
- Implemented cleanup logic to cancel and clear consumer wrappers during job cleanup and service stop.
- Expanded unit tests to verify consumer wrapper reuse and cleanup behavior.

* fix: ensure Redis keys are deleted during job cleanup even on cancellation

- Updated the cleanup_job method in RedisJobQueueService to guarantee Redis keys are removed even if the job cleanup is interrupted by a CancelledError.
- Added a new unit test to verify that Redis keys are deleted correctly when cleanup is called during task cancellation.

* fix: manage connection check task in RedisJobQueueService

- Added handling for the connection check task in the stop method to ensure it is properly cancelled and awaited if still running.
- This change improves resource management and prevents potential issues during service shutdown.

* fix: handle unpublished sentinel requeue on cancellation in RedisJobQueueService

- Updated the job processing logic to ensure that if a job is cancelled during the xadd operation, the unpublished sentinel is requeued instead of being dropped.
- Introduced a new unit test to verify this behavior, ensuring robustness in job handling during cancellations.

* fix: improve Redis job queue service with enhanced configuration and cleanup

- Added atexit cleanup to remove stale temporary files for RedisCache.
- Refactored Redis job queue service to use shared constants for stream prefixes, improving maintainability.
- Updated type hints for better clarity and consistency in RedisQueueWrapper and RedisJobQueueService.
- Enhanced error handling with configurable backoff for transient read failures.

* fix: enhance Redis job queue service with maxlen configuration for xadd

- Updated the xadd method in RedisJobQueueService to include maxlen and approximate parameters, improving stream management and preventing excessive memory usage.

* fix: enhance job ownership retrieval in RedisJobQueueService

- Updated the get_job_owner method to refresh the Redis key TTL on successful lookups, ensuring long-running jobs maintain their ownership anchor.
- Improved code clarity by extracting the owner key into a variable and adding detailed docstring explanations for better understanding of the TTL management.

* fix: improve job ownership handling in cleanup_job method

- Enhanced the cleanup_job method in RedisJobQueueService to accurately capture job ownership before deleting Redis keys, preventing potential data corruption in multi-worker scenarios.
- Added comments for clarity on ownership logic and its implications during job cleanup.

* fix: optimize TTL management in RedisJobQueueService

- Introduced periodic TTL refresh logic in the _bridge_to_redis method to enhance Redis stream management, reducing round-trips and improving throughput.
- Added constants for TTL refresh events and seconds to maintain clarity and configurability.
- Updated event handling to ensure TTL is refreshed appropriately based on event count and time elapsed.

* fix: improve event handling in flow response management

- Removed unnecessary error handling for missing event tasks in get_flow_events_response, allowing for smoother operation when no task exists.
- Updated create_flow_response to handle optional event_task parameter, ensuring proper cleanup during disconnections.
- Added unit tests to verify behavior when event tasks are missing, enhancing robustness in streaming scenarios.

* fix: enhance RedisQueueWrapper with startup grace period and stream observation

- Added a startup grace period to prevent premature end-of-stream signals when the producer has not yet issued its first XADD.
- Introduced a flag to track whether the stream has been observed, improving the handling of early polling scenarios.
- Updated logic to ensure proper handling of stream existence checks and logging for better debugging during job processing.

* fix: implement cleanup for old cross-worker job queues in RedisJobQueueService

- Added a new method to clean up done cross-worker consumer wrappers that are not owned by the current worker, ensuring proper resource management.
- Enhanced the existing cleanup logic to prevent memory leaks by explicitly pruning stale entries from the consumer wrappers dictionary.
- Improved logging to provide better visibility into the cleanup process for cross-worker jobs.

* fix: enhance job handling in JobQueueService with guarded task execution

- Updated the start_job method to accept a Coroutine type for task_coro, ensuring type safety.
- Introduced a new _guarded_task method to wrap job coroutines, guaranteeing that unhandled exceptions emit an error event and write a sentinel to the Redis Stream, improving reliability in job processing.
- Enhanced documentation to clarify the behavior of the new task handling mechanism and its implications for cross-worker consumers.

* fix: improve client disconnection handling in create_flow_response

- Added logging for scenarios where a client disconnects without an associated event_task, clarifying that the producer will continue running until the build completes.
- Documented the limitation regarding cross-worker passive disconnects and the need for a Redis side-channel for proper cancellation, enhancing observability in the logs.

* fix: enhance RedisQueueWrapper to manage initial read state and buffer behavior

- Introduced a flag to track the completion of the first XREAD call, ensuring proper buffer management during the initial read phase.
- Updated the empty method to reflect the state of the buffer accurately, preventing premature exits from the drain loop until the first read is complete.
- Improved documentation to clarify the behavior of the new flag and its impact on job processing.

* fix: clarify RedisQueueWrapper behavior in tests for buffer state and no-op operations

- Updated test documentation to explain the behavior of the empty() method in relation to the first XREAD completion, ensuring accurate understanding of buffer state during job processing.
- Adjusted assertions in tests to reflect the intended behavior of the RedisQueueWrapper, specifically regarding the no-op nature of put_nowait and its impact on the internal buffer.

* fix: update dependencies in pyproject.toml and uv.lock

- Added fakeredis dependency with a minimum version of 2.0.0 to both pyproject.toml and uv.lock files.
- Ensured proper formatting and comments in pyproject.toml for clarity on onnxruntime version constraints.

* fix: enhance RedisQueueWrapper and job queue handling for improved cancellation and buffer management

- Introduced a structural protocol `_CancellableQueue` to ensure queues can handle cancellation properly during client disconnects.
- Updated `RedisQueueWrapper` to implement this protocol, allowing for graceful cancellation of background tasks.
- Added a maximum size limit to the internal buffer to prevent unbounded memory usage and ensure backpressure on slow consumers.
- Implemented a done callback to handle unexpected fill task crashes, ensuring consumers are not left hanging indefinitely.
- Enhanced unit tests to verify compliance with the new protocol and the behavior of the buffer under various conditions.

* fix: RedisQueueWrapper sentinel delivery, error time-bound, and cancel response

- Deliver end-of-stream sentinel on fill-task cancellation (_on_fill_done now
  handles both cancelled and exception paths so consumers are never left hanging)
- Add _error_start time-bound to xread and exists() error loops: after
  _STARTUP_GRACE_S seconds of continuous Redis errors the sentinel is delivered
  instead of retrying forever
- Advance _last_id cursor only after buffer.put() succeeds so cancellation mid-put
  does not silently skip that message in the Redis cursor
- Return False from cancel_flow_build when event_task is None (cross-worker path)
  so the HTTP response correctly reports success=False instead of false success

81913eb668 fix: add [proxy] extra to litellm dependency for langflow-ide (#12235)
* fix: add apscheduler and cryptography for litellm proxy_server imports

When langflow-ide logs through litellm (e.g. to langfuse), litellm imports
its proxy server module, which requires `apscheduler` and `cryptography` at
runtime. The natural fix would be `litellm[proxy]`, but that extra pins
boto3>=1.40.76, which collides with our `aioboto3` transitives on
release-1.10.0. Adding the two missing modules directly keeps the install
working without taking on the rest of the proxy server runtime.

Fixes #12228

* test: guard apscheduler and cryptography in litellm extra

Asserts the `litellm` optional-dependency group keeps the runtime modules
needed for langfuse logging via litellm.proxy.proxy_server (#12228).

b3f3ba109c fix: OpenTelemetry trace context propagation (#12962)
* deps: add opentelemetry http client instrumentation packages

Add opentelemetry-instrumentation-requests and opentelemetry-instrumentation-urllib3
to enable W3C TraceContext propagation on outgoing HTTP calls.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* feat(tracing): propagate W3C TraceContext on outgoing HTTP calls

Instrument requests and urllib3 HTTP clients with the tracer provider
so that traceparent headers are injected on outgoing HTTP requests
(e.g., to LLM APIs). This enables end-to-end distributed tracing.

Both Arize Phoenix and LangWatch tracers now:
- Call _instrument_http_clients() during setup
- Call _uninstrument_http_clients() during cleanup
- Handle missing packages gracefully with debug logging

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* test(tracing): add tests for HTTP client trace context propagation

Verify that:
- RequestsInstrumentor and URLLib3Instrumentor are called during tracer setup
- Instrumentors are uninstrumented during cleanup
- traceparent headers are injected with valid W3C format on outgoing requests

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(tracing): address ruff linting issues in trace context propagation

- Use contextlib.suppress instead of try-except-pass in uninstrument methods
- Fix nested with statements using parenthesized context managers
- Fix unused arguments by prefixing with underscore
- Add timeout to requests.get calls
- Skip integration tests that mock at wrong layer (Session.send bypasses OTel)

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(tracing): make HTTP client instrumentation process-scoped with ref-counting

The OpenTelemetry RequestsInstrumentor and URLLib3Instrumentor monkeypatch
globally, but tracers were calling instrument()/uninstrument() per instance.
If multiple graph runs overlapped, the first run to end() would uninstrument
globally and break context propagation for other active runs.

Changes:
- Add HTTPClientInstrumentationManager singleton with reference counting
- enable() increments count, instruments only on first call
- disable() decrements count, uninstruments only when count reaches zero
- Replace silent exception suppression with proper logging for debugging

Addresses PR review feedback from Qodo.
