Verifying Diff Dad changes at runtime

Launch a server with the current source

The daemon is the easiest surface — it registers the shared config routes and runs straight from source (no rebuild needed for CLI-side changes; frontend changes need bun run build first since the server serves packages/web/dist).

# background it; --no-open suppresses the browser
bun packages/cli/src/cli.ts daemon --port=45677 --no-open

# readiness probe
curl -s http://localhost:45677/api/config

Check nothing is already on the port first (lsof -iTCP:45677 -sTCP:LISTEN). Kill when done: lsof -tiTCP:45677 -sTCP:LISTEN | xargs kill.

Useful endpoints

• GET /api/config — redacted saved config (secrets become *Set booleans).
• POST /api/config/test — what the settings page "Test connection" buttons call. Always returns 200 with {ok, detail}; candidate fields overlay the saved config, so an omitted aiApiKey uses the stored one:

  curl -s -X POST http://localhost:45677/api/config/test \
    -H 'content-type: application/json' \
    -d '{"kind":"ai","aiProvider":"anthropic","aiModel":"claude-sonnet-5"}'
  

  {"kind":"github"} tests the effective GitHub token instead.
• PUT /api/config — merge-patch save (broadcasts over SSE config event).

Gotchas

• POST /api/config/test with kind: ai makes ONE real API call against the user's stored key (16-token ping) — cheap, but it's live.
• The AI test has a 15s timeout; the local-CLI path (defaultCli) is much slower than the API path and can hit it.
• Config lives in the dataDir (see getConfigPath() in packages/cli/src/config.ts); the daemon reads it fresh per request, so config edits don't need a restart — but code edits do.
