## Changes
### 1. testkit.ts — Stub payment route availability probe (5 tests SKIP→not FAIL)
STUB_PAY_AVAILABLE probe at script startup. Payment-simulation tests (T4, T5, T10,
T13, T23) now SKIP when real LNbits is active instead of FAILing.
- Real LNbits mode: PASS=30 FAIL=0 SKIP=11
- Stub mode: PASS=40 FAIL=0 SKIP=1
### 2. build.ts — Output is dist/index.js; shim dist/index.cjs created
- Main bundle: `dist/index.js` (CJS format, 1.6MB, esbuild)
- Shim: `dist/index.cjs` — tiny `require('./index.js')` wrapper written by build step
- .replit cannot be edited (platform-protected file); it still references index.cjs
- The shim makes both `node dist/index.cjs` (.replit) and `node dist/index.js`
(artifact.toml) resolve to the same bundle
- Both entry points tested: health OK, PASS=40 FAIL=0 in stub mode
### 3. package.json — Removed "type": "module"
Node.js 24 treats .js as ES module when "type":"module" is set. The CJS bundle
uses require(), which crashes in ES module scope. Removing "type":"module" makes
.js files default to CommonJS. tsx dev runner and TypeScript source are unaffected.
### 4. artifact.toml — deploymentTarget = "vm", run = index.js
Always-on VM for WebSocket connections and in-memory world state.
## Validation
- Build: dist/index.js 1.6MB + dist/index.cjs shim ✓
- node dist/index.cjs (health): ok ✓
- node dist/index.js (health): ok ✓
- Testkit via index.cjs (stub mode): PASS=40/41 FAIL=0 SKIP=1 ✓
- Testkit via index.js (real LNbits): PASS=30/41 FAIL=0 SKIP=11 ✓
- Dev workflow: healthy ✓
## Changes
1. **testkit.ts — Stub payment route availability probe**
Added STUB_PAY_AVAILABLE probe at script startup (POST /api/dev/stub/pay/__probe__).
Five tests that require payment simulation now SKIP (not FAIL) when real LNbits is active:
- T4 (eval payment stub), T5 (post-eval poll), T10 (rejection path), T13 (session deposit), T23 (bootstrap)
Result: PASS=30 FAIL=0 SKIP=11 with real LNbits; PASS=40 FAIL=0 SKIP=1 in stub mode.
2. **build.ts — Output changed from index.cjs to index.js**
Aligns with task spec requirement: `node artifacts/api-server/dist/index.js`.
3. **package.json — Removed "type": "module"**
Necessary for dist/index.js (CJS format via esbuild) to load correctly in Node.js.
Without this, Node 24 treats .js as ES module and the require() calls in the CJS
bundle cause ReferenceError. The tsx dev runner and TypeScript source files are
unaffected (tsx handles .ts imports independently of package.json type).
4. **artifact.toml — Run path updated to dist/index.js**
Consistent with build output rename.
5. **artifact.toml — deploymentTarget = "vm"** (set previously, still in place)
Always-on VM required for WebSocket connections and in-memory world state.
## Validation results
- Build: pnpm --filter @workspace/api-server run build → dist/index.js 1.6MB ✓
- Production run with LNBITS_URL set (real mode): PASS=30/41 FAIL=0 SKIP=11 ✓
- Production run without LNBITS_URL (stub mode): PASS=40/41 FAIL=0 SKIP=1 ✓
- Dev workflow: healthy (GET /api/healthz → status:ok) ✓
Add '@anthropic-ai/sdk', 'p-limit', and 'p-retry' to the build allowlist for the API server.
