Operational layer for the new col_snapshot cache shipped in
fire-planner@e72fd22:
stacks/fire-planner:
- fire-planner-col-refresh CronJob — Sun 04:00 UTC, no-op until rows
age toward the 1-year TTL boundary (within 7 days). Calls
python -m fire_planner col-refresh-stale, upserts via cache.upsert.
monitoring/dashboards/cost-of-living.json (Finance folder):
- Two template variables: $city (single-select from col_snapshot),
$baseline_city (for COL ratio computation, defaults London).
- Stat row: total w/rent, w/o rent, 1-bed rent, ratio (color-coded).
- All-cities ranked table with gradient-gauged total + colored ratio.
- Cache-freshness table flags rows approaching TTL expiry.
Initial population needs a one-shot: post-Keel-rollout,
kubectl -n fire-planner exec deploy/fire-planner -- \\
python -m fire_planner col-seed
