 ## Monorepo layout
 
 - pnpm workspace (Phase 0 of `svelte-big-bang.md`): the React app lives in `apps/web-react/` — every `app/...`, `e2e/...`, `scripts/...`, `locales/...`, `migrations/...` path below is relative to it
-- `packages/` holds extracted libraries (`@sendou/in-game-lists`, `@sendou/tournament-engine`); never import them via relative paths, always via the package name
+- `packages/` holds extracted libraries (`@sendou/in-game-lists`, `@sendou/tournament-engine`, `@sendou/utils`, `@sendou/build-analyzer`, `@sendou/map-list-generator`, `@sendou/scanner-core`); never import them via relative paths, always via the package name
 - `tooling/codemods/` has the migration codemods and the `migration-manifest.json` updater; `pnpm run <script>` at the repo root delegates to `apps/web-react`, so root commands keep working as documented

 ## Scanner feature (app/features/scanner)
 
 - computer-vision match-event detection; full docs in `app/features/scanner/README.md` — read it before touching detector/recognition code
+- the detection core lives in the `@sendou/scanner-core` workspace package (`packages/scanner-core`); capture, UI, Node helpers, tests, and fixtures stay in the feature folder
 - OpenCV ROI-view gotcha: `.data`/`.clone()` are broken on ROI views — always `view.copyTo(freshMat)` before pixel access
 - fixture workflow: every live misread becomes a fixture under `app/features/scanner/tests/fixtures/`; ground-truth labels are hand-corrected by the maintainer and definitive over any matcher output
 - test with `pnpm test:scanner`; accuracy report with `pnpm scanner:report`; atlas regen commands and the assets-repo/CDN flow are in the README

 Notes on the shape:
 
-- **Workspaces are reserved for things with a real boundary**: the UI kit (developed against the showcase, testable standalone, knows nothing about sendou.ink) and self-contained blocks like `tournament-engine` — pure logic that could ship as its own library: no db imports, no i18n, no app state. Candidates beyond the engine: `map-list-generator`, `in-game-lists`, the scanner's detection core. A block gets extracted only when its boundary is *already* clean — extraction is a promotion, not a project.
+- **Workspaces are reserved for things with a real boundary**: the UI kit (developed against the showcase, testable standalone, knows nothing about sendou.ink) and self-contained blocks like `tournament-engine` — pure logic that could ship as its own library: no db imports, no i18n, no app state. Extracted so far: `in-game-lists`, `tournament-engine`, `utils`, `build-analyzer`, `map-list-generator`, `scanner-core`. A block gets extracted only when its boundary is *already* clean — extraction is a promotion, not a project.
 - **Features are plain folders inside `apps/web`**, same as today — they keep importing each other freely, repositories stay inside their feature folder, and there is no cycle-breaking project because there are no forced package boundaries between features.
 - **Route files are thin shells.** We use SvelteKit's folder routing, but a `+page.svelte` carries no logic of its own: it composes a few components imported from `lib/features/<name>/` and wires in the feature's remote functions — **~100 lines max per route component**. Everything real (components, remote functions, repositories, utils) lives in the feature folder, exactly as `routes.ts` + feature folders work today; only the wiring moved into the filesystem. The `route-map` codemod generates route files in this shape, and a lint check keeps them thin so the fleet can't quietly grow logic into `src/routes/`.
 - **db and i18n live inside `apps/web`** — single consumer, no workspace overhead. During the migration window `apps/web-react` keeps its own frozen copies; drift is impossible by policy because the schema doesn't change during the migration (a boring migration needs no new tables) and locale JSONs are shared by both apps read-only.
