/**
 * `airtrail-sync` cron tick request-context ratchet (Plan 3d Task 0,
 * deliverable 4b — inventory §12, the Plan 3a `*-003` shape
 * `orm-request-context-seams.test.ts`'s SEAM-003 established for
 * `PlaceShadowRetentionJob`).
 *
 * `AirtrailSyncJob.tick` → `AirtrailSyncService.runAirtrailSync` →
 * `syncOwner` is the ONLY cron in the program that reaches a 3d service
 * (`ReservationsService.getReservation`/`.update`, inventory §12's boot/cron
 * table) — `airtrail-sync-boot` is already in BOOT-SWEEP-001's name list
 * (it reads `app_settings` only, raw), but nothing before this file drove
 * the TICK itself (not the boot sweep) through the real, production-wired
 * `CronRegistrarService` into `ReservationsService`. `register()` already
 * wraps every registered tick in `withRequestContext` unconditionally, fail
 * closed on a missing ORM (`cron-registrar.service.ts`) — this pins that the
 * wrap is actually reached from THIS job's tick, the same way SEAM-003 pins
 * it for `PlaceShadowRetentionJob`'s.
 *
 * `ReservationsService` is not yet repository-backed (Plan 3d Tasks 2/4
 * convert it) — the wrap around `getReservation` below performs a REAL
 * repository read from exactly the point in the tick where the real,
 * converted implementation will sit, proving the context is live now, ready
 * for that conversion, the same technique `feeds-request-context.test.ts`'s
 * SEAM-FEED-001 uses for the anonymous ICS routes.
