 **Status:** 🟩 Done

End-to-end pilot-quality service; no domain logic yet.

+- The Processor connects to Redis and joins consumer group `processor` on stream `telemetry:teltonika` (configurable; must match tcp-ingestion's compiled default). On startup it creates the group with `MKSTREAM` if missing.
 - Every `Position` record published by `tcp-ingestion` lands as exactly one row in the `positions` hypertable, with `device_id`, `ts`, GPS fields, and the IO `attributes` bag preserved as `JSONB` (sentinel-decoded — bigint values become `numeric`, Buffer values become `bytea` or `text` per the spec in task 1.2).
 - Per-device in-memory state (`last_position`, `last_seen`, `position_count_session`) is updated on every record and bounded by an LRU cap.
 - `XACK` is sent only after the Postgres write succeeds. A crashed instance leaves work pending; on its next start it picks up via consumer-group resumption, and any other instance can claim its pending entries (full `XAUTOCLAIM` polish lives in Phase 3, but the basic resumption works in Phase 1).
