Python (ml/serving):
- Validate tip item after JSON parse: non-empty content, valid kind
- Retry on schema failure with a targeted clarification prompt, same 2× retry budget
- JSON parse failures keep the existing retry suffix
TypeScript (recommender):
- Add TipSource 'fallback' to shared-types
- FALLBACK_TIPS: 12 general-purpose life tips (hardcoded, no DB read)
- fetchOrchestratorTip returns {ok} discriminated union instead of null
- On !res.ok or fetch error: serve a random fallback tip with rationale 'AI service issues'
- Update tests: 204 path removed; both failure cases now expect source='fallback'

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.
