Ship the scaffolding for #99 (phase B.3 of #81): - ml/serving: add /score/egreedy/v2, /reward/egreedy/v2, /stats/egreedy/v2 endpoints (D=12). New feature dims: completion/dismiss rates, mean dwell (clipped 10min), preferred-hour alignment (cosine, 1-dim), tip volume (log). Separate state file per user (_egreedy_v2.json). /reset clears v2 state too. - ADR-0012: documents D=7→12 dimension change, normalization choices, shadow rollout protocol, and promotion gate (offline sim win per ADR-0002). - recommender.ts: register egreedy-v2-shadow in shadow-policy map (disabled by default). When enabled, calls /score/egreedy/v2 fire-and-forget and publishes shadow:egreedy-v2-shadow serve signal. No reward to shadow — sim is the gate. - sim runner/personas: personas carry synthetic profile_features per persona; _call_score/_call_reward thread profile_features through (None-safe for v1/linucb). - 18 new Python tests; all 56 Python + 170 TS tests pass.

Backend modules. Each owns a contract and ships its own README.md. In Phase 0 these are internal packages inside a single Node process (ADR-0003); they extract to their own processes as pressure justifies.
| Dir | Role | Phase-0 shape | Extracts when |
|---|---|---|---|
gateway/ |
BFF for clients; auth check; fan-out | in-proc router | never (stays as the edge) |
auth/ |
Google OAuth (Apple in M1), sessions, JWT | Auth.js behind OIDC shape | mobile native ships (M3) |
profile/ |
user profile, preferences, consents | in-proc module | team ownership diverges |
integrations/ |
connectors + encrypted token vault | in-proc module | credential blast-radius isolation |
recommender/ |
POST /recommend — policy-driven tip selection |
in-proc; calls ml/serving from M1 |
scaling hotspot |
events/ |
event bus + signal log | in-proc emitter; bridges to NATS JetStream when NATS_URL set (ADR-0010) |
always a library + broker, not a service |
notifier/ |
push/email delivery + quiet hours | in-proc; web push in M1 | SLA divergence or mobile push scale |
Contracts that cross module lines (HTTP or events) come from packages/shared-types/. In-module imports across modules are forbidden by import lint.
