+All Tier 1+2 features verified end-to-end on `space.l.warehack.ing`.
+
+## Deployment Steps Executed
+
+1. `docker compose build db` — rebuilt db image from local pg_orrery checkout (already on `phase/spgist-orbital-trie`)
+2. `docker compose up -d db` — recreated db container
+3. `docker compose exec api-dev alembic upgrade head` — ran migration 022 (`ALTER EXTENSION pg_orrery UPDATE TO '0.18.0'`)
+4. `docker compose build api-prod && docker compose up -d api-prod` — rebuilt prod API image
+
+**Gotcha encountered:** Both `api-dev` and `api-prod` register identical Caddy labels for the same domain. Caddy round-robins between them. Rebuilding only `api-dev` left `api-prod` serving stale responses without shadow state fields on ~50% of requests. Had to rebuild both.
+
+## Verification Results
+
+### Saturn Ring Tilt ✓
+
+```
+GET /api/targets/planet/saturn/position
+ring_tilt_deg: 3.635
+magnitude: 0.869  (ring-corrected, was ~1.1 globe-only)
+```
+
+### Penumbral Eclipse ✓
+
+```
+GET /api/passes?sat=25544&hours=48&min_elevation=5
+Pass 4: shadow=[umbra, umbra, sunlit] penumbra_exit=2026-03-01T11:10:17Z
+Pass 5: shadow=[umbra, sunlit, sunlit] penumbra_exit=2026-03-01T12:43:17Z
+```
+
+Tri-state shadow labels and penumbra transition timestamps flowing correctly through the full stack.
+
+### Rise/Set SRFs ✓
+
+```
+GET /api/sky/rise-set?target=moon&target_type=moon&days=3
+6 events in single query (was ~14 chained queries)
+
+GET /api/sky/rise-set?target=sun&target_type=sun&days=2
+16 events: rise/set via SRF + 6 twilight types via chaining, sorted chronologically
+```
+
+### Direct SQL Verification ✓
+
+```sql
+SELECT extversion FROM pg_extension WHERE extname = 'pg_orrery';
+-- 0.18.0
+
+SELECT saturn_ring_tilt(NOW());
+-- 3.635
+
+SELECT satellite_shadow_state(tle_from_lines(l1, l2), NOW()) FROM satellite WHERE norad_id = 25544;
+-- sunlit
+
+SELECT planet_angular_rate(5, 6, NOW());
+-- -0.006 deg/hr (Jupiter-Saturn approaching)
+```
+
+## Status
