utils/logger.cts — console-compatible log.{debug,info,warn,error} with:
- level gating (LOG_LEVEL; debug in dev / info in prod), and
- REDACTION of secrets/PII (sensitive keys + bearer/JWT) so tokens,
passwords, and encrypted values never reach the logs (financial app).
Backend is abstracted (console now, swappable to pino later).
Swept all 317 server-runtime console.* across 35 files → log.* + inserted
the import at correct scope. tests/logger.test.js pins the redaction
contract (4 tests). CODE_STANDARDS updated; raw console.* is now banned in
server code.
Verified: check:server + typecheck:server + lint clean; 240/240 server
tests; client 50/50; build; e2e probe 17/17; boot smoke logs flow through
the logger and graceful shutdown intact.

The living rulebook (formatting, modules, API/wire + error contract,
security, logging, data integrity, testing) so conventions are codified
and persist. CONTRIBUTING points at it and the CI gate.
