Backend was endpoint-mapper (POST /api/campaigns ignores path id, etc). Adapter translation layer brittle, untested, lost doc identity. Generic contract (Layer 2) test caught 15 bugs immediately. Rewrite to firebase-mirror KV model: - server/db.js: docs table (path PK, parent, data JSON). getDoc/setDoc/updateDoc/ deleteDoc/getCollection/batchWrite. parent = path prefix for collection queries. - server/index.js: generic REST (GET/PUT/PATCH/DELETE /api/doc, GET /api/collection, POST /api/collection addDoc, POST /api/batch). WS subscribe by path (doc|collection), broadcast to doc subs at changed path + collection subs at parent path. - src/storage/ws.js: thin passthrough adapter. norm() strips firebase prefix. initial value via REST (independent of WS connect), subsequent changes via WS. - shared/turn.js kept (M4 use). server/handlers.js + server.test.js removed (logic now in App, backend is dumb KV). - src/storage/contract.js: flush() bumped to 50ms (WS roundtrip > setTimeout(0)). Layer 2 test (server/ws-contract.test.js): spins fresh backend per test, runs same storage contract spec against createWsStorage. Catches adapter translation bugs that firebase-mock Layer 1 tests cannot. nanoid v5 ESM breaks jest CJS -> replaced with crypto.randomUUID (Node builtin). Tests: 114 green (39 shared + 19 ws-contract + 56 frontend).
