# Handoff — 2026-09-17 — Source code analysis document

## State

Documentation-only session. Created `docs/source-code-analysis.adoc`: an AsciiDoc summary of the whole codebase (architecture, Go packages, frontend modules/components, endpoints, WebSocket protocol, tests, Makefile, design decisions, limitations). Verified against the sources via an Explore pass, not just copied from memory. No code, tests or config touched; quality gate not re-run (nothing to measure).

## Notes

- The document sits at `docs/source-code-analysis.adoc`, outside the Diátaxis en/fr quadrants — it is a one-off analysis artifact, not part of the bilingual user docs. If it is later promoted into the doc set, it belongs in `explanation/` and would need a French counterpart (see `ebook-sync`-style rule the docs follow).
- Counts recorded in it: ~3,064 Go LOC / ~3,252 TS+TSX LOC; 55 Go tests + 1 e2e; ~215 vitest cases. These will drift — treat as a 2026-09-17 snapshot (`:revdate:` is set).

## Next steps

- Unchanged from the previous handoff (`2026-09-17-acp-webapp.md`): pending final commit of docs/memory/module-rename, real-browser trial, tickets 0002/0003, evolution list. This new .adoc is also uncommitted.
