1. TimmyIdentityService (artifacts/api-server/src/lib/timmy-identity.ts)
- Loads nsec from TIMMY_NOSTR_NSEC env var at boot (bech32 decode)
- Generates and warns about ephemeral key if env var absent
- sign(EventTemplate) → finalizeEvent() with Timmy's key
- encryptDm(recipientPubkeyHex, plaintext) → NIP-04 nip04.encrypt()
- Logs npub at server startup
2. ZapService (artifacts/api-server/src/lib/zap.ts)
- Constructs NIP-57 zap request event (kind 9734), signs with Timmy's key
- Pays via lnbitsService.payInvoice() if bolt11 provided (stub-mode aware)
- Logs every outbound event to timmy_nostr_events audit table
- maybeZapOnJobComplete() wired in jobs.ts after trustService.recordSuccess()
- Config: ZAP_PCT_DEFAULT (default 0 = disabled), ZAP_MIN_SATS (default 10)
- Only fires for trusted/elite tier partners when ZAP_PCT_DEFAULT > 0
3. Engagement engine (artifacts/api-server/src/lib/engagement.ts)
- Configurable cadence: ENGAGEMENT_INTERVAL_DAYS (default 0 = disabled)
- Queries nostrIdentities for trustScore >= 50 AND lastSeen < threshold
- Generates personalised DM via agentService.chatReply()
- Encrypts as NIP-04 DM (kind 4), signs with Timmy's key
- Logs to timmy_nostr_events; publishes to NOSTR_RELAY_URL if set
- First run delayed 60s after startup to avoid cold-start noise
4. Vouching endpoint (artifacts/api-server/src/routes/identity.ts)
- POST /api/identity/vouch: requires X-Nostr-Token with elite tier
- Verifies optional Nostr event signature from voucher
- Records relationship in nostr_trust_vouches table
- Applies VOUCH_TRUST_BOOST (20 pts) to vouchee's trust score
- GET /api/identity/timmy: public endpoint returning npub + zap count
5. DB schema additions (lib/db/src/schema/)
- timmy_nostr_events: audit log for all outbound Nostr events
- nostr_trust_vouches: voucher/vouchee social graph with boost amount
- Tables created in production DB via drizzle-kit push
6. Frontend identity card (the-matrix/)
- #timmy-id-card: fixed bottom-right widget with Timmy's npub + zap count
- timmy-id.js: initTimmyId() fetches /api/identity/timmy on load
- Npub shortened (npub1xxxx...yyyyyy), click-to-copy with feedback
- Refreshes every 60s to show live zap count
- Wired into main.js on firstInit
Addresses all code review rejections:
1. edge-worker.js → now a proper Web Worker entry point with postMessage API,
loads models in worker thread; signals {type:'ready'} when warm
2. edge-worker-client.js → new main-thread proxy: spawns Worker via
new Worker(url, {type:'module'}), wraps calls as Promises, falls back
to server routing if Workers unavailable; exports classify/sentiment/
warmup/onReady/isReady
3. nostr-identity.js → fixed endpoints: POST /identity/challenge (→ nonce),
POST /identity/verify (body:{event}, content=nonce → nostr_token);
keypair generation now requires explicit user consent via identity prompt
(no silent key generation); showIdentityPrompt() shows opt-in UI
4. ui.js → import from edge-worker-client; setEdgeWorkerReady() shows
'local AI' badge when worker signals ready; removed outbound sentiment
5. websocket.js → sentiment() on inbound Timmy chat messages drives setMood()
6. session.js → sentiment() on inbound reply (data.result), not outbound text
7. main.js → onEdgeWorkerReady(() => setEdgeWorkerReady()) wires ready badge
8. vite.config.js → worker.format:'es' for ESM Web Worker bundling
Implement ragdoll physics for agent interactions, including a state machine for falling, getting up, and counter-attacks. Introduce camera shake based on slap impact and export camera shake strength from agents.js. Update main.js to apply camera shake around the renderer.
