What it is for

application-scheduling — Layer 3 module. Sprint 58: services extracted.

B-009: migrations() previously returned Vec::new() and migrate_pending returned Ok(0) while ignoring the pool, so schedules, availability_blocks, time_slots, appointments, and schedule_exceptions (plus their RLS policies and helper functions, crates/domain/scheduling/migrations/001_scheduling_init.sql) were never created by anything that actually called this module's own migration path. Mirrors application-encounters's pattern.

B-035: the vendored file itself currently fails against real Postgres (time_slots_capacity_check is declared twice on the same table — once auto-named from an unnamed column check, once explicit). Not fixed here; pinned by crates/application/scheduling/tests/pg_forge_scheduling.rs's migrate_pending_currently_fails_pre_existing_bug_b035. This module's own wiring is correct — it vendors the file byte-for-byte.

Public surface

`crate root`

Item	What it is
`pub struct SchedulingModule`	—

`SchedulingModule :: fn name(& self) -> & 'static str`	—

`SchedulingModule :: async fn migrate_pending(& self, pool : & PgPool) -> Result <u32, MigrationError>`	—
`SchedulingModule :: fn permission_codes(& self) -> Vec <String>`	Sprint 3.7 S1 T5 — this module previously declared NO permission codes at all, which meant a host had nothing to seed and nothing to gate on while `api/scheduling_admin` happily served 8 unauthenticated-by-default routes, three of which mutate appointment state

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._
