This feature introduces article summarization into the processing pipeline. Key changes: - The `ContentAnalysisService` has been updated to instruct the LLM to generate a 2-3 sentence summary of the article content. This summary is then parsed from the LLM's response. - The `process_article` Celery task now retrieves this summary and saves it to the `summary` field of the `Article` model. - The RSS feed generation (`UserFeed` in `feeds.py`) already utilized the `article.summary` field, so generated summaries will now automatically be included in the feed item descriptions. - Added `docs/pipeline_overview.md` to document the end-to-end article processing pipeline, including the new summarization step. - Added unit tests for `ContentAnalysisService` to verify summary extraction. - Updated tests for the `process_article` task in `test_tasks.py` to ensure summaries are correctly saved and handled, including a new focused test for summary saving and fixes to existing complex tests like `test_content_analysis_called_once_for_auto_feed`.

The summary is obtained solely from the first chunk analysis. Consider documenting or implementing a more robust strategy to combine summaries from multiple chunks if needed.

The validation now requires a summary in the LLM response. If the summarization is non-critical, you might consider defaulting missing summaries in the LLM response instead of immediately raising an error.

Bug: LLM Response Handling Conflict
Inconsistent handling of the 'summary' field from the LLM response. The code validates that 'summary' must be present and raises an error if missing, but then attempts to extract it using .get("summary", "") with a default value. This makes the default value unreachable and contradicts the likely intent to handle missing summaries gracefully.

These changes aim to enhance clarity regarding the development environment configuration. * chore: update requirements.txt to specify versions for PyPDF2 and add pydantic - Updated PyPDF2 to require version >=3.0.0 and <4.0.0 for compatibility. - Added pydantic with version constraints >=2.0 and <3.0 to the requirements. These changes ensure better dependency management and compatibility with future updates. * fix: resolve 14 failing test categories and update OpenAI API usage This commit addresses multiple test failures and updates the codebase to work with current OpenAI API standards: **API Updates:** - Update ContentAnalysisService to use `max_completion_tokens` instead of deprecated `max_tokens` parameter - Update MODEL_TOKEN_LIMITS with current OpenAI model context windows (128k for GPT-4o/GPT-4o-mini) - Fix token calculation logic to properly handle total context vs completion tokens **Migration Command Fixes:** - Fix audio path migration rollback functionality by tracking file moves immediately after execution - Fix test data setup to use proper legacy audio file paths for migration testing - Improve error handling and rollback operations in migrate_audio_paths command **Test Fixes:** - Update Article model tests to reflect current title field max_length (1024 vs 255) - Fix OpenAIUsageStats __str__ method tests to expect "LLM usage" prefix - Fix service test mock setup to properly return JSON strings instead of MagicMock objects - Correct migration test expectations for permission errors and rollback scenarios **Results:** - Reduced failing tests from 43 to 29 (33% improvement) - Fixed all migration, model, content analysis, and service test categories - Improved test suite stability and reliability 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * fix: resolve 8 failing tests - improved test suite pass rate from 89.8% to 94.1% - test_migration_handles_missing_files: Fix logic error expecting 'audio/' path for unchanged legacy files - test_get_feed_voice_mode_default: Update expectation to 'auto' matching Feed model default - test_post_creates_new_article: Fix form field name from 'voice' to 'voice_id' for ArticleDetailForm - test_apply_preset_to_article: Correct assertion to check standard voices in 'voice' field per single source of truth - test_preset_edit_view: Use valid speed choice (0.9) and fix redirect assertion - test_process_article_permanent_error_no_retry: Add missing OpenAI client mock - test_worker_service_uses_start_worker_script: Correct expectation for worker script vs web script - test_devcontainer_updated: Update docker-in-docker version to current 2.12.2 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * fix: resolve 10 failing tests across multiple test suites - Fixed text chunking logic in _legacy_find_best_break_point to properly detect forced splits - Improved multi-voice test mocking and disabled ChunkToneService for legacy path testing - Added missing OpenAI client mock in url_import test - Updated views_followed_feed tests for Django 5.2 compatibility (assertFormError → context access) - Fixed HTML entity encoding in test assertions 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * fix: resolve failing tests by enhancing MockAudioSegment and ChunkToneService voice handling - Add missing methods to MockAudioSegment: silent(), set_frame_rate(), __iadd__(), duration_seconds - Fix ChunkToneService to respect article voice settings in fallback scenarios - Update get_payload() and create_fallback_payload() to accept fallback_voice parameter - Add fallback voice determination logic in tasks.py before ChunkToneService calls - Fix test voice field usage: use 'voice' field for standard OpenAI voices instead of 'voice_id' - Add override_settings for legacy path tests to bypass ChunkToneService when testing ContentAnalysisService Resolves AudioSegment.silent AttributeError and improves voice configuration consistency.
