2026-03-25: Sentiment Timeline Port
- Ported Sentiment Timeline into the codex runtime-first architecture.
Summary
- Ported Sentiment Timeline into the codex runtime-first architecture.
- Added a reusable sentiment-analysis engine with AI and lexicon modes.
- Added a dedicated
/app/sentimentpage, thin route wrapper, tests, and docs.
Why It Matters
- The analysis parity batch now includes emotional trend analysis alongside topic and writing analysis.
- The port removes duplicated provider logic and keeps sentiment caching in one shared module.
