## 0.22.11
Released: 2026-04-02
### Highlights
- Cleaned up the most obvious BGP/Earth cleanup leftovers from the recent stabilization work without changing the current user-facing interaction model.
### Improved
- Improved [bgp.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/bgp.js) by factoring the BGP Earth loading flow into smaller helpers, separating timed GeoJSON fetch fallback from `incident vs anomaly` render-mode selection.
- Improved [bgp.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/bgp.js) by extracting shared feature parsing helpers so anomaly and incident marker preparation no longer duplicate coordinate, severity, and timestamp parsing logic.
- Improved [visualization.py](/home/ray/dev/linkong/planet/backend/app/api/v1/visualization.py) by consolidating repeated BGP evidence geography parsing into a shared helper used by both anomaly and incident geography-hint builders.
- Improved planning hygiene in [TODO.md](/home/ray/dev/linkong/planet/TODO.md) by recording the deferred `bgp.js` responsibility split as an explicit follow-up task instead of leaving the idea only in conversation context.
### Refined
- Refined [constants.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/constants.js) by removing stale Earth BGP configuration entries that were left behind after the floating event hub design was removed.
- Refined [bgp.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/bgp.js) by removing no-longer-used arc helpers that only served the deleted off-surface hub/link route.
- Refined [visualization.py](/home/ray/dev/linkong/planet/backend/app/api/v1/visualization.py) by dropping an unused `_lookup_prefix_geography` import after the earlier rollback from expensive live prefix-geography visualization lookups.
### Fixed
- Fixed the codebase drift where Earth BGP cleanup patches had left behind dead constants, duplicate parsing branches, and fallback-loading glue that was harder to reason about than the now-stable runtime required.
