# @v2/telemetry-debug-mode

Development-only verbose telemetry debug logging for Phase 72.5.1.10.

`debugTelemetryBatch` emits one sanitized debug record for every event in a
development, test, QA, or staging batch when debug mode is explicitly requested.
Release, production, and shipping builds always return `release-build-disabled`
and write nothing to the sink.

Payload logging is enabled by default in non-release debug mode, but
`sanitizeTelemetryDebugPayload` redacts forbidden ingestion fields and sensitive
token/password/secret fields before formatting a log line. Set
`includePayload: false` for metadata-only logging.

Targeted verification:

```bash
pnpm --filter @v2/telemetry-debug-mode run typecheck
pnpm --filter @v2/telemetry-debug-mode run test
python V2/ue/Tools/check-v2-telemetry-debug-mode.py
```
