+  - `pool_uuid` is the unique identifier for the pool (key)
+  - `map_ids` is a list of map IDs managed by this pool

+  Handles automatic recovery from duplicate map slug scenarios.
+
+  This module provides functions to:
+  - Detect duplicate slugs in the database (including deleted maps)
+  - Automatically fix duplicates by renaming newer maps
+  - Verify and recreate unique indexes (enforced on all maps, including deleted)
+  - Safely handle race conditions during recovery
+
+  ## Slug Uniqueness Policy
+
+  All map slugs must be unique across the entire maps_v1 table, including
+  deleted maps. This prevents confusion and ensures that a slug can always
+  unambiguously identify a specific map in the system's history.
+
+  The recovery process is designed to be:
+  - Idempotent (safe to run multiple times)
+  - Production-safe (minimal locking, fast execution)
+  - Observable (telemetry events for monitoring)
