"""Tests for the satpass persisted-timer `due_at` column.

Pending satellite-pass consolidations used to be scheduled only as in-memory
asyncio TimerHandles, so a restart orphaned any satpass_pending rows: the row
survived but its timer did not, and it was never consolidated/broadcast. The
fix persisted a durable `due_at` on each pending row and added a startup
sweep (`CentralConsumer._sweep_pending_satpass`) that reconstructed a timer
for every pending consolidated_id off its persisted due_at.

The Central NATS consumer (and `_sweep_pending_satpass` with it) was retired
2026-07 -- the sweep's tests are gone with it. The native satpass path
(env/satpass.py) never used the satpass_pending buffer or this sweep in the
first place (it consolidates in-memory within a single tick), so nothing
live is affected. What remains here:
  - `due_at` is persisted on the normal ingest path (satpass_handler.py,
    still live -- shared by both paths historically, now native-only)
  - SCHEMA_VERSION == 26 and the v22 migration (which added the due_at
    column) still applies cleanly on a fresh DB
