david kiania e71c8914f1 feat(geocode): two-pass estate fallback for building-level location_names
Building-level names (e.g. 'KAHAWA WENDANI ALVO HOUSE') aren't in OSM, so the
precise forward-geocode 404s and tickets stay on the bare cluster centroid
(observed 0/133 placed). geocode_locations now tries an ordered set of
candidates per location (compose_queries): full precise -> estate (leading 2
tokens) -> leading token, each constrained by the existing cluster viewbox +
25km distance check, accepting the FIRST in-range hit. This places tickets in
the right neighbourhood (e.g. 'KAHAWA WENDANI', 'BAMBURI') instead of the broad
cluster centroid. Wrong-area matches for ambiguous coarse tokens are rejected by
the distance check and fall through; genuinely unmatchable tickets keep the
honest cluster-centroid fallback (no pure-cluster candidate, which would only
mislabel the centroid as geo_source='location'). Verified the cascade finds
hits against live LocationIQ on real samples.

import_tickets.py — Fireside Communications · INC ticket ingestion (raw-first)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Loads the client's field-ops INC ticket snapshots into the `tickets` schema — the
source of the FleetOps "Tickets" map.
tickets.inc — incidents / customer faults
STRICTLY INC: CRQ (new-installation) exports are out of scope and not processed
here. `tickets.crq` stays in the schema but is not fed by this pipeline.
RAW-FIRST: each row stores only `ticket_id` + `raw` (the source record as jsonb).
Everything downstream reads from `raw` (resilient to source schema drift). The DB
derives `geom` (see migrations): feed coords (raw lat/lng) -> location geocode
(tickets.geo_locations) -> cluster centroid (tickets.geo_clusters) -> none.
Source data: the n8n hourly S3 export (see n8n-hourly-s3-full-data-exports.md)
writes a full current-state snapshot CSV per hour to the `tickets` bucket at
automations/inc/<EAT-timestamp>.csv (e.g. 2026-06-15T17-00-00.csv)
There is NO latest pointer, NO metadata envelope, and NO deltas — each file is a
flat CSV (header + rows). We ingest the NEWEST file:
- skip-if-unchanged: if its S3 ETag matches the last processed file's ETag we
skip the DB write (the export re-emits byte-identical content most hours);
- drop is_alarm=true rows + the "EXPORT STOPPED…" truncation-sentinel row;
- drop derivable / provenance / zero-info columns (see DROP_FIELDS);
- normalize region -> lowercase, raw_status -> UPPERCASE;
- upsert on ticket_id (PRIMARY KEY → no duplication; never delete, so closure
history accumulates), and record snapshot freshness in tickets.import_meta;
- on success, MOVE the file to automations/inc/processed/ (copy + delete).
Geocoding (two layers, both via a KEYED provider — public Nominatim rate-limits):
--geocode-clusters one coordinate per cluster (coarse fallback; ~50 lookups)
--geocode-locations precise per-location for ACTIONABLE INC tickets: parses the
real place out of location_name (region+cluster+location_name,
network codes stripped), geocodes it, caches in
tickets.geo_locations, then re-resolves geoms.
Provider/key from env: GEOCODER_PROVIDER (locationiq|opencage), GEOCODER_API_KEY.
Usage (needs DATABASE_URL + RUSTFS_* + GEOCODER_* env; see .env.example):
python import_tickets.py --from-bucket --apply
python import_tickets.py --inc-csv 2026-06-15T17-00-00.csv --apply
python import_tickets.py --geocode-clusters --apply
python import_tickets.py --geocode-locations --apply
Pre-requisite: migration applied (run_migrations.py) — tickets.inc/crq +
geo_clusters + geo_locations + reporting.fn_tickets_for_map.
