M2: replace shape-specific backend with generic KV doc store (firebase mirror)
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).

M2: fix ws adapter for browser WebSocket + firebase path prefix
- WebSocketImpl: native browser WebSocket if present, else ws pkg (node/jest)
- ensureWs: use onopen/onmessage/onerror/onclose property handlers (browser API)
instead of ws.on('open') EventEmitter (node-only) — was silent no-op in browser
- norm(): strip 'artifacts/{APP_ID}/public/data/' prefix from all paths
App passes firebase-prefixed paths; backend uses canonical campaigns/...
- apply norm() to getDoc/getCollection/setDoc/updateDoc/deleteDoc/addDoc/
subscribeDoc/subscribeCollection/changeTypesForDocPath/changeTypesForCollPath
Verified: STORAGE=ws boots, WS subscribe fires, backend broadcast -> browser
live update (curl POST campaign -> appears without reload). Cross-device sync
confirmed end-to-end.
