Stage discovered the wrong default at runtime: tcp-ingestion's compiled
default REDIS_TELEMETRY_STREAM is 'telemetry:teltonika' but processor's
was 'telemetry:t', so the two services were talking past each other —
tcp-ingestion publishing to one stream, processor reading another empty
one. The deploy stack now pins both to the same value via a shared env
var, but the processor's compiled default should also match so local
development and the integration test stay aligned with reality.
Changes:
- src/config/load.ts — default changed to 'telemetry:teltonika'
- .env.example — same
- test/config.test.ts — default-value assertion updated
- planning docs (ROADMAP, phase-1 README, tasks 03/08/10, phase-3 README) —
occurrences of 'telemetry:t' replaced with 'telemetry:teltonika'
The deploy stack remains the single source of truth via the shared
REDIS_TELEMETRY_STREAM env var. Compiled defaults are belt-and-braces.
Scaffold mirrors tcp-ingestion conventions: ESM, strict TS, pnpm, vitest
with unit/integration split, ESLint flat config with no-floating-promises
+ no-misused-promises + import/no-restricted-paths (the new src/core/ →
src/domain/ boundary that protects Phase 1 from Phase 2 churn).
Core types in src/core/types.ts (Position, StreamRecord, DeviceState,
Metrics, AttributeValue) — Position is byte-equivalent to tcp-ingestion's
output. Codec in src/core/codec.ts implements sentinel reversal:
{__bigint:"..."} → bigint, {__buffer_b64:"..."} → Buffer, ISO timestamp
string → Date. CodecError surfaces malformed payload reasons with the
failing field named.
Config in src/config/load.ts (zod schema, all 13 env vars with defaults
and bounded numerics). Logger in src/observability/logger.ts matches
tcp-ingestion exactly: ISO timestamps, string level labels, pino-pretty
in development.
Postgres in src/db/: createPool with sane defaults and application_name,
connectWithRetry mirroring the ioredis retry pattern, a 30-line
migration runner using a schema_migrations table, and 0001_positions.sql
with the hypertable + (device_id, ts) unique index + ts DESC index.
Migration runner unit-tested against a mocked pg.Pool; the real
TimescaleDB round-trip is deferred to task 1.10 per spec.
Verification: typecheck, lint, build all clean; 73 unit tests passing
across 4 files. import/no-restricted-paths verified live by temporarily
adding a forbidden src/domain/ import.
