Drop the dormant ops (workshop / tickets / dispatch / SLA / odometer)
and dwh_gold (nightly ETL aggregates) schemas plus their dependents —
features never implemented, no live writer or scheduled refresh.
- Prod DB (already applied): DROP SCHEMA ops/dwh_gold CASCADE, plus
tracksolid.dispatch_log, v_sla_inflight, v_utilisation_daily.
- migrations/12_drop_ops.sql + 13_drop_dwh_gold.sql (forward, all
IF EXISTS) registered in run_migrations.py for rebuild durability.
- grafana: removed 8 now-broken panels (In-flight SLA, Idle Cost,
Utilisation Heatmap, Row 7 Field-Service SLAs) from daily_operations;
panel count 21 -> 13.
- docs: scrubbed CLAUDE.md, PLATFORM_OVERVIEW.html (-19KB), DATA_FLOW.md;
pre-drop seed snapshot in docs/reports/260605_ops_purge_backup.md.
The separate tracksolid_dwh server (31.97.44.246:5888) is unrelated
and untouched.
