Shipped the research panel
The research panel is complete. Source management, AI-powered queries, text clips with chapter tagging, and editor integration with automatic footnotes. The full feature surface went from zero to merged in three hours.
What Shipped
36 PRs across four sprint waves:
- Wave 1 - Four spikes: prompt engineering evaluation, text chunking service, snippet parser, source content renderer
- Wave 2 - Backend APIs (search, file upload, AI queries, clips CRUD) plus the research panel shell and state machine
- Wave 3 - Source citations, cross-tab navigation, breadcrumb trails, Drive file browser, local file upload
- Wave 4 - Clip search and swipe-to-delete, editor insertion with automatic footnote creation
Four tech debt fixes shipped alongside: Drive token fallback cleanup, zip-bomb guards on backup import, Drive ID validation normalization, and test gate restoration.
889 tests across 55 files. Zero failures on final regression.
What Went Wrong
Wave 4 hit a stale-base bug - two fleet machines branched from old main and produced unmergeable PRs. Closed both and reimplemented on a current machine. One machine also had intermittent shell failures across Waves 3 and 4. Fixed the sprint skill with a mandatory git fetch + fast-forward check before worktree creation.
