# fleettickets

Field-ops **INC ticket** ingestion, geocoding, and read-schema that powers the
**Tickets** map in FleetOps. Extracted from the `tracksolid` repo into its own module
(it previously lived there as migrations 21–23 + `tools/import_tickets.py`).

- **INC** — incident / customer-fault tickets *(this pipeline is **strictly INC**)*
- **CRQ** — new-installation requests *(schema kept, but **out of scope** — not ingested here)*

## What this owns

| Piece | What |
|---|---|
| `migrations/01_tickets_schema.sql` | The `tickets` schema: `tickets.inc` / `tickets.crq` (raw-jsonb-first), `tickets.geo_clusters` + `tickets.geo_locations` gazetteers, geom-resolution trigger, and `reporting.fn_tickets_for_map` (the GeoJSON read function) |
| `migrations/02_import_meta.sql` | `tickets.import_meta` (per-dataset snapshot envelope metadata) + `fn_tickets_for_map` re-defined to expose it as `summary.freshness` (same signature — dashboard_api unchanged) |
| `import_tickets.py` | Ingests the **newest INC CSV** from the rustfs `tickets` bucket (`automations/inc/<EAT-timestamp>.csv`) and upserts on `ticket_id`; geocodes clusters + INC locations |
| `run_migrations.py` | Applies `migrations/*.sql` in order (ledger: `tickets.schema_migrations`) |
| `shared.py` | Minimal DB/logging helpers (self-contained — no tracksolid dependency) |

## What this does NOT own (stays where it is)

- **The DB** — the `tickets` schema lives in the shared `tracksolid_db`.
- **The read-API** — `dashboard_api` (in the tracksolid stack) serves
  `GET /webhook/tickets`, which calls `reporting.fn_tickets_for_map` (defined here).
- **The frontend** — the Tickets map is a tab in the **FleetOps** SPA (`fleetops` repo).

## Data model (raw-first)

Each row is just `ticket_id` + `raw` (the full source record as `jsonb`) + a derived
`geom` / `geo_source`. Everything reads from `raw`, so a change to the source schema
needs no migration. `geom` is resolved: **feed** coords (`raw` lat/lng) → **location**
(geocoded `location_name`) → **cluster** centroid → **none**.

Source coordinates are empty in the feed, so geocoding is required:
- `--geocode-clusters` — one coordinate per cluster (coarse fallback).
- `--geocode-locations` — precise per-location for **actionable INC** tickets: strips the
  network codes from `location_name` (e.g. `NW_`, `ADR_MNT_`, `FDT<n>`, `SDUS`), geocodes
  the real place via a **keyed** provider (LocationIQ / OpenCage), and **rejects any result
  >25 km from the cluster centroid** (wrong-city guard). Results cache in
  `tickets.geo_locations`.

## Setup

```bash
uv sync
cp .env.example .env        # fill in DATABASE_URL, RUSTFS_*, GEOCODER_*
python run_migrations.py    # apply the schema (idempotent)
```

## Run

```bash
# ingest the newest INC CSV from the bucket (skip-if-unchanged, then archive)
python import_tickets.py --from-bucket --apply

# geocode (needs GEOCODER_API_KEY)
python import_tickets.py --geocode-clusters  --apply   # coarse, once
python import_tickets.py --geocode-locations --apply   # precise, actionable INC

# from a local CSV instead of the bucket (dev)
python import_tickets.py --inc-csv 2026-06-15T17-00-00.csv --apply
```

Dry-run is the default (omit `--apply`). `import_tickets.py --from-bucket` shells out to
the `aws` CLI using the `RUSTFS_*` env (no boto3 dependency). Hourly on the instance via
cron `5 * * * *` (a few minutes after each export).

## Notes

- The n8n export writes a **full current-state CSV per hour** to
  `automations/inc/<EAT-timestamp>.csv` — no `latest` pointer, no metadata envelope, no
  deltas. The loader lists the prefix, takes the **newest** file, and ingests it.
- **Skip-if-unchanged:** the newest file's S3 **ETag** is compared to the last processed
  file's ETag (stored in `tickets.import_meta.metadata.source_etag`); if equal, the DB write
  is skipped (the export re-emits byte-identical content most hours).
- **Upsert on `ticket_id`** (PRIMARY KEY) — duplication is impossible; rows are never
  deleted, so closed-ticket history accumulates. On success the file is **moved** to
  `automations/inc/processed/`.
- **Cleaning at ingest:** drop `is_alarm=true` rows + the `EXPORT STOPPED…` sentinel; drop
  `week_start`/`week_end`, `source_s3_*`/`source_snapshot_id`, `department`/`source_type`;
  normalize `region` → lowercase and `raw_status` → UPPERCASE. `service_type` and `bucket`
  (a `closed`/`pending` flag) are kept.
- `tickets.import_meta` captures snapshot freshness (surfaced as `summary.freshness` by
  `fn_tickets_for_map`).
- The curated/geocoded coordinates are written `verified = false` — review
  `tickets.geo_clusters` / `tickets.geo_locations` and flip `verified` once checked.
