- Add CORSMiddleware (disabled by default, enabled via CORS_ENABLED=true)
- Add cors_enabled, cors_allowed_origins, cors_allow_credentials,
cors_allowed_methods, cors_allowed_headers settings to config.py
- Add parse_comma_separated_list validator for CORS list env vars
- Insert CORS middleware between SessionMiddleware and ProxyHeaders
so preflight runs before CSRF/auth but after proxy-header processing
- Document CORS env vars in .env.demo with rationale for proxy-first approach
- Mark CORS TODO as completed in SECURITY_AUDIT.md
- Add tests/test_cors.py with 12 unit and integration tests

- Add RequestSizeLimitMiddleware that checks Content-Length header
before request body is read: non-multipart requests capped at
MAX_REQUEST_BODY_SIZE (default 1 MB), multipart uploads capped at
MAX_UPLOAD_SIZE (default 1 GB). Returns HTTP 413 on violation.
- Register middleware in app/main.py
- Add max_request_body_size setting to app/config.py
- Fix ui_upload in files.py to check Content-Length early and read
in 64 KB chunks (bounded memory usage), removing the post-write
os.path.getsize check
- Document MAX_REQUEST_BODY_SIZE in .env.demo and ConfigurationGuide.md
- Mark SECURITY_AUDIT.md item #4 as resolved
- Add 9 tests in test_request_size_limit.py
- Update test_upload_file_too_large to use patch.object instead of
the now-unused os.path.getsize mock
Closes#173

- Implement step timeout detection to prevent files from getting stuck in 'pending' state
- Add monitor_stalled_steps periodic task running every minute (Celery Beat)
- Automatically mark in-progress steps as failed if they exceed timeout (default: 10 minutes)
- Add step_timeout configuration setting (default: 600 seconds)
- Recover stalled steps with error message indicating when timeout was triggered
- Fix duplicate check to exclude self-comparison (file not duplicate of itself)
When processing crashes or hangs:
1. Worker detects stalled steps (in_progress for >10 minutes)
2. Marks them as failed with timeout error message
3. Updates UI to show failure status
4. Allows file to be retried or handled by user
This prevents files from being indefinitely stuck in processing state and provides
visibility into what went wrong.
- Add enable_deduplication and show_deduplication_step config options
- Rename hash_file step to check_for_duplicates
- Make deduplication step conditional based on configuration
- Add is_duplicate and duplicate_of_id fields to FileRecord model
- Create database migration for new deduplication fields
- Update process_document task to log deduplication results
- Update step visualization to show/hide step based on config
- Update status calculations to include deduplication step conditionally
- Default: deduplication enabled, step displayed
- Can be configured to hide from UI while still processing
- Update generate_build_metadata.sh to sync VERSION from latest git tag
- Change BUILD_DATE format from date-only to ISO 8601 with time (YYYY-MM-DDTHH:MM:SSZ)
- Fix VERSION file from 0.5.0 to 0.9.1 (matching latest git tag v0.9.1)
- Change version fallback from hardcoded '0.5.0-dev' to 'unknown' in config.py
- Update release.yml to commit all build metadata files (not just VERSION)
- Update BuildMetadata.md documentation to reflect automated versioning
- Add tests for build_date with time format and version unknown fallback

Security headers are now disabled by default since most deployments use a reverse proxy (Traefik, Nginx) that already adds these headers. Enable with SECURITY_HEADERS_ENABLED=true for direct deployments.
Changes:
- Set security_headers_enabled default to False in app/config.py
- Update all documentation to reflect new default
- Comment out examples in .env.demo (now showing disabled state)
- Update SECURITY_AUDIT.md to reflect reverse proxy as default deployment
- Tests still pass (3 passed, 8 skipped as expected with headers disabled)
