# Packet Station

Digital job packets for the PESCO shop floor. A packet moves through each department on screen instead of on paper. VISUAL releases the work and Packet Station builds the packet with the drawing from M-Files at the rev the job pull calls. Clerical checks anything flagged. Warehouse pulls parts and records heat numbers, MTRs and shorts. A supervisor assigns a station and welder. The station logs welds on the weld map, works the checklist and runs the timer. The supervisor sends it to Q.C. Q.C. inspects, accepts or rejects, and adds reports. Clerical closes the job in VISUAL, exports the manufacturing data book PDF and files it. A change in VISUAL to a packet already in the shop goes to Clerical as a change order before it reaches the shop.

This repo is the rebuild of Packet Station as a server application: Docker Compose on `docker-1`, PostgreSQL 16, a Python server that enforces every rule, a worker for the VISUAL feed and M-Files drawing lookups, and a React frontend as a pure client. Sign-in is PESCO's Active Directory. VISUAL is read through VisualKit and M-Files through MFilesKit, read-only.

## Status

**Rebuild in progress. Phase 8 done: the Project Management screen with its reports and exports, the find bar on every home screen with server-side filters and the list view, presence in packets, the motion switch, and the data book checked page by page against the old build.**

People can sign in, set up projects and units, make hand drafts, attach a drawing, and send a packet to the warehouse, a department or Q.C. The worker reads released work orders from VISUAL on a schedule, makes and updates drafts, opens change orders on packets already in the shop, looks drawings up in M-Files and attaches them at the rev VISUAL calls. Clerical sees it all on the From VISUAL panel and in the Flagged and Changes to approve columns; Admin sets the feed up on the Feed tab. Warehouse works its task board (waiting, being pulled, on hold, pulled, released), pulls parts line by line with heat numbers, shorts, receipts and MTRs, and releases to the supervisor once every line is pulled or short and every pulled line has a heat. A supervisor assigns the packet to a station and a welder, the welder starts the clock, marks welds on the drawing, places the heat table, finishes the checklist and submits with a PIN signature, and the supervisor sends it to Q.C. or routes it to another department with the marks carried. Department supervisors verify change orders with a signature. Q.C. inspects the packet on its own tab (the check items, a visual result per weld, NDE, hardness, notes), accepts it to the data book, to Shipping or on to another department with a PIN signature, or rejects it back to the supervisor with a reason or an NCR number. Q.C. keeps project folders of documents per project and unit (ITP, WPS / PQR, procedures, certificates) where a new revision supersedes the old one and nothing is deleted, adds reports to a packet for the data book and takes them out with a reason, and works each unit's digital ITP from the Q.C. template through line initials, N/A, rejects with NCR numbers, section block signatures and a sign-off. Open hold and witness points show as a warning on the unit's packets. Clerical confirms the job closed in VISUAL (the feed's closed state and any open work orders shown beside it) and files the packet with a signature. Filing seals the packet with an HMAC and builds the manufacturing data book on the server, stored on the seal; filing past open work orders needs a second confirmation. IT can reopen a filed packet with a reason and a signature, which keeps the broken seal and its data book. Anyone who can open a packet can view or download the data book, the job traveler with the work order QR codes, the ITP PDF and the traceability CSV, and print a stamped copy of the traveler, the drawings with the heat or weld map, the drawings without markup, the VOID sheets, the data book or any document. Every copy carries a stamp signed with the seal key, and every print and export is logged. The ITP sign-off files the signed ITP PDF. Every packet write goes through the server policy. The old build on `M:\Production\Packet Station` stays the live system until go-live. The new system starts empty; nothing is migrated from M:.

Not in git: `.env`, `tests/fixtures/local/`, `reference/`, `recordings/`. Real job data stays out of git and CI.

## How to run

Developer machine:

```bash
python -m venv .venv
.venv\Scripts\python -m pip install -e ".[dev]"
.venv\Scripts\python -m pytest
cd frontend && npm ci && npm run build
packetstation doctor
```

`visualkit` and `mfileskit` install from PESCO's Gitea index with `--index-url`. Everything else installs from public PyPI in a separate step. See [docs/DEPLOY.md](docs/DEPLOY.md).

Test stack on `docker-1`:

```bash
docker compose -p packetstation-test --env-file ~/packetstation/test/stack.env \
  -f deploy/compose.yaml -f deploy/compose.proxy.yaml up -d
```

Phase 2 adds `/api/projects`, `/api/units`, `/api/packets` (header, transitions, work orders, pages, documents, BOM, shorts, welds, heat tags, heat table, stage, checklist, clock, warehouse stage, Q.C., change orders, log, seal), `/api/assets` and `/_blob/{id}`. Every packet read carries `can`, `blocked` and `holder` from the policy. See [docs/POLICY.md](docs/POLICY.md) and [docs/SCHEMA.md](docs/SCHEMA.md).

The `packetstation` command has `doctor`, `migrate`, `app`, `worker`, `job run <name>` (one job in the foreground), `fixtures use N` (switch the fixture state, never on prod), `ad-groups --list` (the 50 AD group names the app expects) and `ad-refresh` (create or refresh the users from the groups' members).

Phase 3 adds the worker (`packetstation worker`: APScheduler, the `visual-feed`, `drawing-lookup` and `housekeeping` jobs, settings re-read on every fire, run now through `job_requests`), the VISUAL and drawing cache tables (migration 0004), `/api/feed/*`, `/api/jobs/*`, `/api/admin/feed/*`, rev approval and hand uploads under `/api/packets/{id}`, and the synthetic fixture generator (`python -m tests.fixtures.generator --out DIR`) that CI feeds the worker with. See [docs/FEED.md](docs/FEED.md).

Phase 6 adds the Q.C. screen (`/qc`: numbers, boards, project folders), `GET /api/qc/home`, `GET /api/qc/folders` with the project and unit folder reads, `POST /api/qc/docs` (a new revision supersedes the old row), the per-key Q.C. endpoints under `/api/packets/{id}/qc`, document kinds as a closed set with take-out reasons, and the digital ITP under `/api/units/{id}/itp` and `/api/itps/{id}` (start, line sign and unsign, N/A, reject with NCR, block sign, sign-off, reopen, log). The ITP PDF filed on sign-off is a hook for phase 7. See [docs/POLICY.md](docs/POLICY.md) "Q.C. (phase 6)".

Phase 7 adds the close and file panel, `confirm_open_wos` on the file transition (409 `open_work_orders` without it), the data book built and stored on the seal at filing, `GET /api/packets/{id}/pdf/databook`, `GET /api/packets/{id}/pdf/traveler`, `GET /api/packets/{id}/export/traceability.csv`, `GET /api/packets/{id}/print/{kind}` (`traveler`, `map-h`, `map-w`, `clean`, `void`, `databook`, `doc`), `GET /api/packets/{id}/prints`, `GET /api/itps/{id}/pdf` and `GET /api/itps/{id}/print`, and the `print_log` table (migration 0008). The PDFs are built on the server with reportlab 5.0.1, pypdf and pypdfium2; the heat and weld map rasters use Pillow 13.0.0. Both are pinned in `pyproject.toml` and `server/requirements.txt`, and need no system package or font in the image. See [docs/POLICY.md](docs/POLICY.md) "Phase 7: close, file, PDFs and prints".

Phase 8 adds the Project Management screen (`/pm`) and its API under `/api/pm` (`overview`, `projects` with `expand=`, `aging`, `hours`, `quality`, `find`, `export.csv?table=<key>|jobs|all`, `report.pdf`), read by any signed-in role and writing nothing; every export is logged as `report exported` in the audit and the print log. The find bar params (`q`, `status`, `dept`, `station_id`, `welder_id`, `flags`, `flag`, `sort`, `mine_screen`, `mine_station_id`, `facets`) are read by `GET /api/packets` and by the shop, stall, warehouse and Q.C. boards, so the server applies every filter; the KPI numbers follow the project pick only. Presence over `/api/events` now carries the role and drops locked sessions (session events `locked` and `unlocked`). No new table or migration. See [docs/POLICY.md](docs/POLICY.md) "Phase 8: Project Management, find bar, presence".

CI stack with the Samba domain controller and the Playwright scenario, on a Docker host:

```bash
deploy/ci/make-secrets.sh
docker compose -p packetstation-ci --env-file deploy/ci/ci.env -f deploy/compose.yaml -f deploy/compose.ci.yaml up -d --build --wait
docker compose -p packetstation-ci --env-file deploy/ci/ci.env -f deploy/compose.yaml -f deploy/compose.ci.yaml --profile e2e run --rm playwright
docker compose -p packetstation-ci --env-file deploy/ci/ci.env -f deploy/compose.yaml -f deploy/compose.ci.yaml down -v
```

Server tests that need PostgreSQL run when `TEST_PG_SUPERUSER_URL` is set; the ones that need the domain controller run when the `TEST_LDAP_*` variables and `TEST_DC_USERS_FILE` are set. See [deploy/samba/README.md](deploy/samba/README.md).
