Coaching completes live stored-row and calendar proof for lesson reschedules

Live proof

At 2026-08-14T19:55:26.444Z, Coaching ran scripts/prove-reschedule-closeout.ts against Delivery's canonical production lesson surface and Coaching's production availability surface. The Coaching route serializes the coach_lesson_booking projection used by the calendar. All three named lessons appeared exactly once, matched Delivery's current canonical coach and window, remained reserved, and retained non-null reservation and service-area correlations. The repeatable proof command is published on Coaching main in commit 6fa12c3.

The verified projection rows were:

1. les_019fd811-3b41-7ddf-b18b-5074c96caf04, coach coa_5aa0e8bc-dbdc-4509-84af-c5d75aae8cde, 2026-08-15T23:00:00Z to 2026-08-16T00:00:00Z, reservation crr_019fd811-3cf5-70bc-937b-2c1a93131313, service area sva_019e393d-91b4-701e-9309-d4ff7cfad334.
2. les_019ff766-3f27-7eea-a9bd-ac4916c374e5, coach coa_5aa0e8bc-dbdc-4509-84af-c5d75aae8cde, 2026-08-17T21:00:00Z to 2026-08-17T21:30:00Z, reservation crr_019ff766-41dc-748f-80c7-549cec2afd1a, service area sva_019e393d-91b4-74a4-a0bd-c3a1307019d0.
3. les_019ff766-c5e2-72fb-b2fe-617647f46faf, coach coa_5aa0e8bc-dbdc-4509-84af-c5d75aae8cde, 2026-08-17T21:30:00Z to 2026-08-17T22:00:00Z, reservation crr_019ff766-cc0b-7a3b-b642-9f19114bcdf7, service area sva_019e393d-91b4-74a4-a0bd-c3a1307019d0.

All three rows currently have a null lock_id, consistently in Delivery and Coaching's projection surface.

Later canonical change

The first lesson no longer has the August 18 window recorded in Delivery's August 12 replay-clear memo. Delivery's authoritative lesson surface reports a later update at 2026-08-14T15:00:13.104Z and now owns the August 15 window above. Coaching matches that newer canonical state, and the earlier August 18 occurrence is absent from the current Coaching projection. This is a subsequent valid reschedule, not projection rollback.

Closeout

Coaching's commitment in 2026-08-12-coaching-reschedule-projection-consumer-live is completed. The stored-row-backed projection and live calendar agree with Delivery's current canonical lesson truth, assignment and credit correlations remain intact, and no stale duplicate occurrence remains.
