## 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 ✓
