Tasks 1.1-1.9 marked done with their landing commit SHAs. Tasks 1.10
(observability), 1.12 (production hardening), and 1.13 (device
authority) marked paused with explicit resume triggers — pilot
deployment on real Teltonika hardware takes priority. Task 1.11
remains as next, in slimmed form for the pilot (no /readyz healthcheck
since the metrics endpoint is part of paused 1.10).
- Bounded in-memory queue (default 10000); overflow throws PublishOverflowError
so the framing layer skips ACK and the device retransmits.
- Background worker drains via XADD with MAXLEN ~ approximate trimming.
- JSON serialization with sentinel encoding for bigint/Buffer/Date; correctly
handles Buffer.prototype.toJSON firing before the replacer.
- AdapterContext.publish(position, codec) with codec-label closure at dispatch
in adapters/teltonika/index.ts; zero changes to the three codec parsers.
- connectRedis with retry-on-startup; main.ts wires the full pipeline.
- installGracefulShutdown stubbed (full hardening in task 1.12).
- 19 new tests (17 unit + 2 Docker-conditional integration). Total 81 passing.
