* 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

* docs: improve sidebar and TOC readability + scroll progress
- Fix left nav sidebar hugging the left edge (remove margin-left)
- Increase sidebar font sizes and lift muted colors for legibility
- TOC right-side: white inactive items, pink active, gray for passed sections
- Add clientModule (tocProgress.js) to track scroll progress in TOC
- Add Redocusaurus API page styles to match site theme
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* docs: fix sidebar/TOC height stability and active item reflow
- Force sidebarViewport to 100vh to prevent shrinking during scroll
- Replace font-weight on active TOC item with text-shadow to avoid reflow
* docs: left-anchor sidebar and increase fonts on large screens
* docs: constrain prev/next nav to match content max-width
* docs: fix sidebar jump on scroll by moving padding-top inside menu
* docs: fix sidebar-ad spacing with transparent padding on li
* docs: fix sidebarViewport height and MutationObserver leak
* docs: constrain doc content to 75vw and remove dead CSS comments
- Cap docMainContainer at 75vw
- Set pagination-nav to 100% width to match content column
- Remove commented-out .markdown and .ch-scrollycoding blocks
* docs: set docMainContainer max-width to 75% for better reading width
* docs: center main-wrapper on large screens and center docItemWrapper
* fix: revert lodash override to stable 4.17.21
lodash 4.18.0 is a broken release — template.js uses assignWith and
arrayEach without importing them, crashing npm start. Pin to 4.17.21
across all nested overrides.
* fix: prevent horizontal scroll on mobile docs pages
docsWrapper has flex:1 0 auto (flex-shrink:0), so it never shrinks below
the natural content width (~570px on iPhone). Cap it to 100vw and add
min-width:0 down the flex chain (docRoot, docMainContainer) so the
layout stays within viewport on narrow screens.
Also remove the overflow:visible override from ch-code-wrapper, which
was defeating the code block's own horizontal containment.
* feat: responsive navbar search and hide social icons on mobile
Shrink search bar as viewport narrows (160px at 1100px, 100px at 996px),
collapse to icon-only at 960px. Hide GitHub, X, and Discord icons below
996px where the hamburger menu takes over navigation.
* fix: images always respect container width above 996px
Use min(100%, 600px) so images are capped at 600px but never overflow
their container when the content area is narrower (e.g. sidebar open).
* fix: improve TOC progress scroll tracking and bottom-of-page detection
Adds scroll handler with RAF throttle, pauses/resumes MutationObserver
to avoid loops, and forces last TOC link active when scrolled to page bottom.
* fix: translate Portuguese comments to English in custom.css
* fix: sidebar viewport fills full screen height
* feat: sidebar section icon turns pink with ease transition when active
* fix: reduce TOC font size to 0.8rem
* fix: remove docMainContainer right padding and add 48px gap to content col
* fix: card header responsive alignment and title margin reset
* fix: darken card background and active sidebar item bg on light theme
* fix: revert TOC colors and add inline code border radius tweak
* fix: minimal scrollbar for sidebar and TOC — thumb only on hover
* fix: scrollbar fade-in/out transition at 0.25s ease
* feat: add rehype plugin for table column wrapping and centering
Inserts zero-width space after underscores in inline code cells so long
env-var names wrap at underscore boundaries. Also centers Format/Default
columns via a col-center class applied at build time.
* fix: use --ifm-heading-color for sidebar group labels in both themes
* refactor: split docs custom.css into themed partials
Breaks the 1,658-line monolithic custom.css into 8 focused files
(tokens, layout, navbar, sidebar, typography, components, code,
redocusaurus). custom.css is now a thin entry point with @imports.
* fix: align sidebar and navbar with shared --docs-gutter token
Introduces --docs-gutter: 1rem in tokens.css and applies it to both
navbar__inner horizontal padding and sidebar nav.menu padding-left,
keeping the Langflow logo and sidebar items visually aligned.
* fix: match sidebar ad background to page background color
Dark mode uses #111 (same as sidebar bg); light mode uses --ifm-background-color.

* fix: pin postgres image to bookworm in docker_example to prevent collation mismatch
The postgres:16 tag silently moved its base from Debian Bookworm
(glibc 2.36) to Trixie (glibc 2.41), causing a recurring collation
version mismatch warning on existing langflow-postgres volumes.
Pin to postgres:16-bookworm in both docker-compose files and update
the README so existing data volumes keep matching the OS locale data.
Refs: https://github.com/langflow-ai/langflow/issues/9608
* docs: pin postgres image to bookworm in current docs compose snippets
Mirror the docker_example pin in the four current docs that publish
copyable Compose snippets pairing postgres:16 with a persistent
langflow-postgres volume. Prevents the same Bookworm-to-Trixie
collation version mismatch warning when users follow docs instead
of docker_example.
Versioned historical docs are left as-is.
Refs: https://github.com/langflow-ai/langflow/issues/9608
* fix: switch postgres pin from bookworm to trixie for OS consistency
Aligns the pinned postgres base with the langflow runtime image, which
moved to Debian Trixie in #12990. Keeping postgres on bookworm would
have diverged the stack and locked the database to an aging glibc that
will receive fewer security backports as bookworm ages into oldstable.
The pin itself still solves the original bug — postgres:16 cannot
silently roll its OS underneath an existing volume.
Document the one-time REFRESH COLLATION VERSION step for users
upgrading from a bookworm-initialized volume in docker_example/README.md.

* fix: URLComponent ignores proxy in async mode (#12285)
The URLComponent fails to connect for users behind corporate proxies
because its asynchronous mode does not recognize standard system proxy
environment variables. The component defaults to use_async=True, which
initializes the RecursiveUrlLoader; the underlying async loader does
not natively respect system proxy environment variables, so the
component attempts a direct connection and fails in restricted network
environments.
Detect standard proxy environment variables (http_proxy, HTTP_PROXY,
https_proxy, HTTPS_PROXY) in URLComponent._create_loader. If a proxy
is detected and use_async is enabled, override use_async to False so
the loader uses its synchronous implementation, which natively
respects system proxies. Empty and whitespace-only values are
correctly evaluated as no-proxy and do not trigger the fallback.
Closes#10297
* fix(URLComponent): broaden proxy detection and harden tests
Address review findings on the proxy fix:
- Add ALL_PROXY and all_proxy to the detected env vars. ALL_PROXY is
commonly set in corporate and container environments (curl, git,
many Unix tools honour it), and is sometimes the only proxy var
configured.
- Replace the unused proxy_url string with a single boolean any() over
the env var keys, since only the presence of a proxy is consulted.
- Reorganize the proxy tests under TestURLComponentProxyHandling with
a shared default-attributes helper, parametrize over all six env var
spellings, and add coverage for multiple-simultaneous-proxies and
the use_async=False path (which should not log a warning).
* [autofix.ci] apply automated fixes
* fix: remove no_proxy="*" macOS startup hack so corporate proxies work
Two startup paths set `os.environ["no_proxy"] = "*"` on macOS, which
disables proxy use for every HTTP client in the process and every child
gunicorn worker (httpx, requests, urllib3 — and therefore the OpenAI,
Anthropic, Groq, etc. SDKs that wrap them). For users behind corporate
proxies on macOS this made every external LLM call unroutable, even with
HTTPS_PROXY properly set.
The override traces to commit history with no concrete justification —
the only artifact is a Stack Overflow link about a uWSGI segfault, but
Langflow uses gunicorn, not uWSGI. Bench-verified that gunicorn boots
cleanly and serves requests on macOS without it (1 worker via
LangflowApplication, OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES retained,
HTTPS_PROXY survives intact in parent and child).
Verification:
- gunicorn worker spawns and serves /health (200 OK), exits cleanly
- httpx, urllib, requests all resolve HTTPS_PROXY after the macOS init
(previously: all three returned empty proxy maps because of no_proxy=*)
- OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES still set — the actual
fork-safety fix is preserved
Closes the macOS half of #10297. Companion fix for the async URLComponent
half is in #12285 / branch pr-12285-rebased.

* fix(security): default WEBHOOK_AUTH_ENABLE to True (unauth webhook execution)
POST /api/v1/webhook/{flow_id} previously executed any user's flow
without authentication because WEBHOOK_AUTH_ENABLE defaulted to False.
Change the default to True so webhook endpoints require an API key and
validate that the caller owns the flow being executed. Operators who
need the prior behavior can explicitly opt in with
LANGFLOW_WEBHOOK_AUTH_ENABLE=False.
Docs updated to reflect the new secure-by-default behavior.
* test(security): add regression tests for WEBHOOK_AUTH_ENABLE default
Guard against a regression of the unauthenticated webhook execution fix:
one test pins the class-level default to True, the other confirms the
runtime config rejects an unauthenticated POST with 403 under defaults.
(cherry picked from commit cb6f7508dd)
* fix: enable preload_app option in LangflowApplication configuration
* feat: Integrate Sentry and Prometheus support in worker lifespan
- Initialize Sentry SDK in the worker lifespan if a DSN is provided, allowing for better error tracking.
- Start Prometheus HTTP server if enabled in settings, enhancing monitoring capabilities.
- Added logging for both Sentry initialization and Prometheus server startup to aid in debugging and monitoring.
Refactor existing code to defer Sentry initialization to avoid issues with process forking. This change improves the overall observability of the application.
* fix: Correct Prometheus port validation logic in create_app function
- Updated the condition for validating the Prometheus port to use 'and' instead of 'or', ensuring that the port is both greater than 0 and less than MAX_PORT. This change enhances the reliability of the Prometheus server configuration.
* test: Add unit tests for LangflowApplication.pre_fork method
- Introduced a new test suite for the pre_fork method in LangflowApplication, covering various scenarios including warnings for non-main threads and non-LISTEN TCP connections.
- Implemented tests to ensure proper handling of psutil import errors and unexpected exceptions.
- Verified that garbage collection is always executed during the pre_fork process.
- Added a fake server mock to facilitate testing without requiring a real server instance.
* refactor: Move telemetry service initialization to lifespan context
- Removed the initialization of the telemetry service from the beginning of the `get_lifespan` function and added it within the lifespan context. This change ensures that the telemetry service is only initialized when needed, improving resource management and application performance.
* fix: Enhance Sentry integration with error handling and import checks
- Added error handling for Sentry SDK initialization to log warnings if the SDK is not installed or if initialization fails.
- Updated the `setup_sentry` function to conditionally import `SentryAsgiMiddleware`, logging a warning if the import fails.
- This improves the robustness of the application by preventing crashes related to missing Sentry dependencies and providing clearer logging for debugging.
* fix: Improve Prometheus server error handling in lifespan context
- Enhanced error handling for starting the Prometheus server by adding specific checks for ImportError and OSError.
- Added logging for cases where the Prometheus client is not installed or when the port is already in use, improving clarity for debugging and operational monitoring.
- This change aims to provide more informative feedback during server startup, enhancing the overall robustness of the application.
* refactor: Rename and enhance Sentry middleware integration
- Changed the function name from `setup_sentry` to `add_sentry_middleware` for clarity.
- Updated the middleware setup to ensure Sentry is attached at request time, deferring SDK initialization to the worker lifespan to avoid ghost transactions.
- Adjusted unit tests to mock the new middleware function name, ensuring continued test coverage and functionality.
* feat: Enhance pre_fork method to identify benign threads before forking
- Introduced a new class-level constant `_BENIGN_THREAD_PREFIXES` to define known benign thread prefixes.
- Added a class method `_is_benign_thread` to check if a thread is benign based on its name.
- Updated the `pre_fork` method to log warnings for non-benign threads, improving thread management during the forking process.
- Added a unit test to ensure no warnings are emitted for benign threads, enhancing test coverage for the `pre_fork` method.
* fix: Improve logging for psutil import error handling
- Added a debug log statement to indicate when the psutil library is not installed, enhancing visibility into the application's behavior during TCP connection checks.
- This change aims to provide clearer feedback for debugging and operational monitoring when the psutil dependency is missing.
* fix: Enhance garbage collection handling in pre_fork method
- Wrapped the gc.collect() call in a try-except block to prevent crashes if an exception is raised during garbage collection.
- Added logging to capture any warnings when gc.collect() fails, improving error visibility during the pre-fork process.
- Introduced a new unit test to ensure that the pre_fork method handles gc.collect() exceptions gracefully while still calling gc.freeze().
* docs: LANGFLOW_GUNICORN_PRELOAD environment variable introduced
* refactor: Update application setup for Windows and non-Windows environments
- Introduced conditional logic to handle application setup differently based on the operating system.
- Added a factory pattern for creating the FastAPI application, improving flexibility for non-Windows systems.
- Enhanced error handling to provide clear runtime messages when the application cannot be initialized correctly.
* refactor: move test_server.py to correct unit/base location
The test file exercises langflow.server which belongs to the base package
(src/backend/base/). Moving it to src/backend/tests/unit/base/ follows the
project convention and aligns with the path expected by CI ruff checks.

* feat: use uv sources for CPU-only PyTorch
Configure [tool.uv.sources] with pytorch-cpu index to avoid ~6GB CUDA
dependencies in Docker images. This replaces hardcoded wheel URLs with
a cleaner index-based approach.
- Add pytorch-cpu index with explicit = true
- Add torch/torchvision to [tool.uv.sources]
- Add explicit torch/torchvision deps to trigger source override
- Regenerate lockfile without nvidia/cuda/triton packages
- Add required-environments for multi-platform support
* fix: update regex to only replace name in [project] section
The previous regex matched all lines starting with `name = "..."`,
which incorrectly renamed the UV index `pytorch-cpu` to `langflow-nightly`
during nightly builds. This caused `uv lock` to fail with:
"Package torch references an undeclared index: pytorch-cpu"
The new regex specifically targets the name field within the [project]
section only, avoiding unintended replacements in other sections like
[[tool.uv.index]].
* style: fix ruff quote style
* fix: remove required-environments to fix Python 3.13 macOS x86_64 CI
The required-environments setting was causing hard failures when packages
like torch didn't have wheels for specific platform/Python combinations.
Without this setting, uv resolves optimistically and handles missing wheels
gracefully at runtime instead of failing during resolution.

* fix: add ondelete=CASCADE to TraceBase.flow_id to match migration (#12002)
* fix: add ondelete=CASCADE to TraceBase.flow_id to match migration
The migration file creates the trace table's flow_id foreign key with
ondelete="CASCADE", but the model was missing this parameter. This
mismatch caused the migration validator to block startup.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix: add defensive migration to ensure trace.flow_id has CASCADE
Adds a migration that ensures the trace.flow_id foreign key has
ondelete=CASCADE. While the original migration already creates it
with CASCADE, this provides a safety net for any databases that may
have gotten into an inconsistent state.
* fix: dynamically find FK constraint name in migration
The original migration did not name the FK constraint, so it gets an
auto-generated name that varies by database. This fix queries the
database to find the actual constraint name before dropping it.

* fix: mcp config issue (#12045)
* Only process dict template fields
In json_schema_from_flow, guard access to template field properties by checking isinstance(field_data, dict) before calling .get(). This replaces the previous comparison to the string "Component" and prevents attribute errors when template entries are non-dict values, ensuring only dict-type fields with show=True and not advanced are included in the generated schema.
* Check and handle MCP server URL changes
When skipping creation of an existing MCP server for a user's starter projects, first compute the expected project URL and compare it to URLs found in the existing config args. If the URL matches, keep skipping and log that the server is correctly configured; if the URL differs (e.g., port changed on restart), log the difference and allow the flow to update the server configuration. Adds URL extraction and improved debug messages to support automatic updates when server endpoints change.

* fix: replace grep -oP with sed for Node.js version extraction in Docker builds
The grep -oP (PCRE regex) command fails in the python:3.12.12-slim-trixie
Docker base image because PCRE support is not available in the slim variant.
This replaces grep -oP with portable sed -nE in all 5 Dockerfiles and adds

* fix(docker): remove broken npm self-upgrade from Docker images
Node.js 22.x now bundles npm 11.x which fails when trying to self-upgrade
via 'npm install -g npm@latest' in the slim Docker image. The bundled npm
version is sufficient.
This is the same fix as PR #12309 on release-1.9.0.

* fix: prevent overwriting user-selected global variables in provider config
Previously, the apply_provider_variable_config_to_build_config function would
automatically overwrite field values with environment variable keys whenever
an env var was present, even if the user had already selected a different
global variable.
This fix adds a check to only auto-set the environment variable if:
- The field is currently empty, OR
- The field is not already configured to load from the database
This preserves user selections while still providing automatic configuration
for new/empty fields.
Added comprehensive unit tests to verify:
- Auto-setting env vars for empty fields
- Preserving user-selected global variables
- Overwriting hardcoded values (expected behavior)
- Skipping when env var is not set
- Applying component metadata correctly
* [autofix.ci] apply automated fixes
* style: use dictionary comprehension instead of for-loop
Fixed PERF403 Ruff style warning by replacing for-loop with dictionary
comprehension in update_projects_components_with_latest_component_versions
* chore: retrigger CI build
* test: improve test coverage and clarity for provider config
- Renamed test_apply_provider_config_overwrites_hardcoded_value to
test_apply_provider_config_replaces_hardcoded_with_env_var for clarity
- Added test_apply_provider_config_idempotent_when_already_set to document
idempotent behavior when value already matches env var key
- Removed sensitive value from debug log message to prevent potential
exposure of API keys or credentials
These changes improve test coverage by documenting the no-op scenario
and enhance security by avoiding logging of potentially sensitive data.
* chore: retrigger CI build

The grep -oP (PCRE regex) command fails in the python:3.12.12-slim-trixie

* fix: disable dangerous deserialization by default in FAISS component
Change the default value of allow_dangerous_deserialization from True
to False to prevent remote code execution via malicious pickle files.
This addresses a security vulnerability where an attacker could upload
a crafted pickle file and trigger arbitrary code execution when the
FAISS component loads the index.

* docs: add PyTorch macOS AMD64 + Python 3.13 investigation (LE-172)
Investigate why the experimental CI job fails on macOS x86_64 + Python 3.13.
Root cause: PyTorch dropped macOS Intel wheel builds after v2.2.2 (before
Python 3.13 existed). The altk and langchain-huggingface extras pull in
torch without platform guards, causing installation failures.
Includes analysis of dependency chains, lockfile resolution behavior,
and 4 actionable options (A-D) with tradeoffs for the team to decide on.
* fix: exclude torch-dependent extras on macOS x86_64 (LE-172)
Add platform exclusion markers to altk and langchain-huggingface extras
to prevent torch from being pulled in on macOS Intel where no wheel exists.
This matches the existing pattern used for easyocr and docling extras.
PyTorch dropped macOS x86_64 binary support after v2.2.2, so these
features cannot work on Intel Macs regardless.
docs: enhance Agentics documentation with embedded video and full paper citations
- Add embedded YouTube tutorial video at the top of the page
- Add introductory text for the video
- Group research papers under Publications section
- Add full academic citations for both Agentics papers
- Remove redundant schema table from introduction
- Improve overall readability and structure
