This subsumes the old 40 km remote clustering (deleted). Regenerated `data/airports_world.csv`: 1483 → 1161 rows (1119 large unchanged, specials 364 → 42; min pairwise special distance 1001.6 km). +- **Tests.** New committed-dataset invariant in `lib/airports.test.ts` (same style as the existing remote-rule test): every pair of non-large rows is at least `REMOTE_RADIUS_KM` apart (pairwise haversine, O(n²) — n≈42). The existing "no large airport within 1000 km" invariant stays and still holds. No runtime code changes in `lib/airports.ts`. + ## v0.67.0 — 2026-09-23 18:03 - **Prune runner dind leftovers after e2e.** The CI runner's full-dind daemon is shared with production and other workflows, so between runs it accumulates what the existing cleanup steps can't reach: dangling images/layers from the per-run `flight-ops-ci` rebuilds, BuildKit cache (persists by design), and job containers leaked by interrupted runs. A new non-fatal "Prune runner dind leftovers" step (`if: always()`, placed after the existing "Cleanup e2e stack + network") runs `docker system prune -af || echo "::warning::dind prune failed — see logs"` so a prune failure can never mask or break the run's real result. Deliberately NO `--volumes`: named volumes on the shared daemon may hold other workflows' persistent data — this project's own `flight-ci_flight-db` volume is already dropped by the existing cleanup steps. No app/TS changes; CI validates the workflow itself. diff --git a/data/airports_world.csv b/data/airports_world.csv index 0fbd6d1..68a671e 100644 --- a/data/airports_world.csv +++
