Part of PAR-166 (spin out /find). Plugin/presentation — new spun-out repo; filed under ChestShop until that project exists.
Port the legacy /csdb resync <chunksPerTick> command: scan loaded chunks for ChestShop signs and upsert each into the registry via MarketApi.upsertShop, throttled per tick (legacy: ResyncCommand + ResyncTaskFactory, TickUtil throttling). This is the live, in-game counterpart to the one-time DB backfill in PAR-169 — useful for repairing drift after the fact, not just initial migration.
Depends on the idempotent bulk-upsert path in PAR-169. Command perm gate (legacy csdb.resync).
