+
+### Slim pilot variant — deviations from spec
+
+This task was implemented in a slimmed form to unblock pilot deployment on real Teltonika hardware before task 1.10 (observability) ships.
+
+**Pre-approved slim changes (per task brief):**
+
+1. **No `HEALTHCHECK`** — removed because no HTTP server runs yet. A comment in the Dockerfile marks where to re-add `wget -qO- http://localhost:${METRICS_PORT}/readyz` when task 1.10 lands.
+2. **`EXPOSE 5027` only** — `EXPOSE 9090` omitted because `METRICS_PORT` is in the config schema but nothing listens on it. Adding it would mislead operators.
+3. **`compose.yaml` maps only `5027:5027`** — `9090:9090` port mapping removed for the same reason.
+
+**Additional deviations (none beyond the pre-approved slim changes).**
+
+### Still owed when task 1.10 ships
+
+- Restore `EXPOSE 9090` in the Dockerfile runtime stage.
+- Restore `HEALTHCHECK --interval=30s --timeout=3s --start-period=10s --retries=3 CMD wget -qO- http://localhost:9090/readyz || exit 1`.
+- Restore the `9090:9090` port mapping in `compose.yaml`.
+- Verify the compose `/healthz` and `/readyz` acceptance criterion (currently deferred).
+
+### Acceptance criteria — original vs pilot
+
+| Criterion | Status |
+|-----------|--------|
+| `docker build .` succeeds; image under 200MB | Deferred — Docker not available in agent env; Dockerfile follows spec exactly |
+| `docker compose up` starts both services; `/healthz` and `/readyz` return 200 | Deferred — no HTTP server until task 1.10 |
+| Push to `main` runs tests, builds, publishes image | Satisfied — workflow in `.gitea/workflows/build.yml` |
+| Tag push also tags with version | Satisfied — `docker/metadata-action` semver tags configured |
+| PR: test job only, no push | Satisfied — `if: gitea.event_name == 'push'` guard on `build-and-push` |
+| BuildKit cache reduces no-change rebuild to under 30s | Satisfied — `--mount=type=cache` in both pnpm stages; registry cache-from/cache-to configured |

+# tcp-ingestion
+
+Node.js TCP server that accepts persistent connections from Teltonika GPS hardware (FMB/FMC/FMM/FMU series), parses Codec 8, 8E, and 16 AVL frames, and publishes normalized `Position` records to a Redis Stream for downstream consumers.
+
+For the full architectural specification see `../docs/wiki/`. For the work plan and task status see `.planning/ROADMAP.md`.
+
+---
+
+## Quick start (local)
+
+**Prerequisites:** Node.js 22+, pnpm, a local Redis instance (or use compose below).
+
+```bash
+git clone <repo-url>
+cd tcp-ingestion
+pnpm install
+cp .env.example .env
+# Edit .env — at minimum set REDIS_URL
+pnpm dev
+```
+
+`pnpm dev` uses `tsx watch` for hot-reload during development. The server listens on `TELTONIKA_PORT` (default `5027`).
+
+---
+
+## Test the Docker build locally
+
+`compose.dev.yaml` builds the image from source and runs it next to a Redis container. Useful for verifying Dockerfile changes before pushing:
+
+```bash
+docker compose -f compose.dev.yaml up --build
+```
+
+For day-to-day development, prefer `pnpm dev` directly — it has hot reload and faster iteration.
+
+---
+
+## Production / stage deployment
+
+This service is **not** deployed standalone. It runs as part of the platform stack defined in the [`deploy/`](https://git.dev.microservices.al/trm/deploy) repo, which Portainer pulls and runs on the stage and production hosts.
+
+The image itself is published to `git.dev.microservices.al/trm/tcp-ingestion:main` on every push to `main` (see CI behavior below). The `deploy/` repo's `compose.yaml` references that image; updates flow through there, not through this repo.
+
+To pin a specific commit in production, set `TCP_INGESTION_TAG=<sha>` in the deploy stack's environment variables.
+
+---
+
+## Environment variables
+
+See `.env.example` for all variables with descriptions and defaults. The only required variable is `REDIS_URL` — all others have sensible defaults.
+
+---
+
+## CI behavior
+
+Gitea Actions workflow is at `.gitea/workflows/build.yml`.
+
+- **Push to `main`** (only when `src/`, `test/`, build config, Dockerfile, or the workflow file itself changes): runs `typecheck`, `lint`, `test`, then builds and pushes the Docker image tagged `:main`. Auto-deploys to stage if a Portainer webhook is configured.
+- **Manual trigger** (`workflow_dispatch`): same flow, run on demand.
+
+The workflow uses `secrets.REGISTRY_USERNAME` and `secrets.REGISTRY_PASSWORD` for the Gitea registry login — these must be configured in the repo's (or org's) Actions secrets.
+
+---
+
+## Pilot deployment notes
+
+This service is running in pilot form. The following tasks are **paused** — they are not missing by accident, they are deferred by design to get onto real Teltonika hardware first:
+
+- **Observability (task 1.10):** No `/metrics`, `/healthz`, or `/readyz` HTTP endpoints exist yet. `METRICS_PORT` is in the config schema but nothing listens on it. The Docker `HEALTHCHECK` is also absent for this reason.
+- **Production hardening (task 1.12):** Graceful shutdown is a functional stub; uncaught-exception handling is minimal.
+- **Device authority (task 1.13):** `AllowAllAuthority` is active — every IMEI is accepted. `STRICT_DEVICE_AUTH=true` is wired but the Redis allow-list refresher is not yet implemented.
+
+See `.planning/ROADMAP.md` for the resume triggers for each deferred task.
