Task #2: MVP Foundation — injectable services, DB schema, smoke test
DB schema
- jobs and invoices tables added to lib/db/src/schema/
- schema barrel updated (jobs, invoices, conversations, messages)
- pnpm --filter @workspace/db run push applied successfully
LNbitsService (artifacts/api-server/src/lib/lnbits.ts)
- Injectable class accepting optional { url, apiKey } config
- Falls back to LNBITS_URL / LNBITS_API_KEY env vars
- Auto-detects stub mode when credentials are absent; logs warning
- createInvoice() -> { paymentHash, paymentRequest }
- checkInvoicePaid() -> boolean
- stubMarkPaid() helper for dev/test flows
- Real LNbits REST v1 calls wired behind the stub guard
AgentService (artifacts/api-server/src/lib/agent.ts)
- Injectable class with configurable evalModel / workModel
- evaluateRequest(text) -> { accepted: boolean, reason: string }
uses claude-haiku-4-5; strips markdown fences before JSON parse
- executeWork(text) -> { result: string } uses claude-sonnet-4-6
- Wired via Replit Anthropic AI Integration (no user API key)
PricingService (artifacts/api-server/src/lib/pricing.ts)
- Injectable class with configurable fee/bucket thresholds
- calculateEvalFeeSats() -> 10 sats (fixed)
- calculateWorkFeeSats(text) -> 50/100/250 by char-length bucket
- Zero LLM involvement; fully deterministic
Smoke test (scripts/src/smoke.ts)
- pnpm --filter @workspace/scripts run smoke
- Verifies LNbits stub: create, check unpaid, mark paid, check paid
- Verifies Anthropic: evaluateRequest round-trip
- Both checks passed
replit.md
- Documented required (LNBITS_URL, LNBITS_API_KEY) and auto-provisioned secrets
- Stub-mode behaviour explained
