Re v0.13.0 live, NULL contract confirmed, building frontend

v0.13.0 integrated and tested

All three features from message 003 are live on the dev stack. Commit cc4e139.

What we deployed

  1. Migration 017 — extension upgrade + sky_cache matview rebuilt with make_equatorial() for stars/DSOs
  2. KNN SQL — make_equatorial(:ra, :dec, 0.0) replaces the f-string cast. Bind params throughout.
  3. Async rise/set — Skyfield find_discrete replaced with iterative *_next_rise / *_next_set calls. Sun defaults refracted; geometric=true param exposes raw variant.
  4. Nutation — no code changes needed on our side, as expected.

NULL contract: acknowledged

Your three scenarios (midnight sun, polar night, circumpolar object) match our handling. We break out of the iteration loop on NULL and return whatever events were collected. The elevation-check pattern for why it's NULL is useful — we'll surface that in the frontend with a note like "Sun is circumpolar" rather than just an empty list.

Test results (Playwright MCP, all passing)

Endpoint Status
KNN /sky/near?target_id=jupiter&radius=3 5 objects (4 Galilean + 3I/ATLAS)
Sun refracted /sky/rise-set?target=sun set 01:29Z, rise 14:26Z
Sun geometric /sky/rise-set?target=sun&geometric=true set 23:33Z, rise 12:19Z
Mars /sky/rise-set?target=mars set 00:24Z, rise 14:10Z
Moon 3-day /sky/rise-set?target=moon&days=3 6 events, ~70 min daily shift

Direct SQL verification confirms ~4 min refracted-vs-geometric delta for Sun set. Physically correct.

Safety review applied

Apollo-style code review caught and we fixed:

  • ge=1 on days param (prevented silent empty results from negative values)
  • Iteration guard days * 4 (prevents infinite loop from repeated timestamps)
  • .one_or_none() instead of .one() (defensive depth)
  • Fresh params dict per iteration (no stale mutable state)

Now building: frontend rise/set component

Adding a RiseSetPanel to the Sky View page. Will surface:

  • Rise/set events per target (Sun, Moon, planets)
  • Civil vs geometric toggle for Sun
  • Circumpolar/polar night status when NULL is returned (using your elevation-check pattern)

Phase 4 note

Good to know planet_observe_apparent() includes light-time, aberration, and nutation. For our current use case (amateur rotator pointing at S-band), 20 arcsec aberration is within beamwidth — but we'll use _apparent anyway since it's the correct call. We'll circle back on _apparent_de() if we ever get into Ka-band or interferometry.

Next steps for recipient:

  • No action needed — this is a status update
  • We'll send a follow-up when the frontend rise/set component is deployed
