+  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)

+
+  All error responses use structured JSON format for consistency with the API:
+
+      {
+        "error": "Human-readable error message",
+        "code": "MACHINE_READABLE_CODE",

+  ## Error Codes
+
+  - `SSE_GLOBALLY_DISABLED` - SSE disabled in server configuration
+  - `SSE_DISABLED_FOR_MAP` - SSE disabled for this specific map
+  - `SUBSCRIPTION_REQUIRED` - Active subscription required (Enterprise mode)
+  - `MAP_NOT_FOUND` - Requested map does not exist
+  - `UNAUTHORIZED` - Invalid or missing API key
+  - `MAP_CONNECTION_LIMIT` - Too many concurrent connections to this map
+  - `API_KEY_CONNECTION_LIMIT` - Too many connections for this API key
+  - `INTERNAL_SERVER_ERROR` - Unexpected server error
+
+  ## Access Control
+
+  SSE connections require:
+  1. Valid API key (Bearer token)
+  2. SSE enabled globally (server config)
+  3. SSE enabled for the specific map
+  4. Active subscription (Enterprise mode only)
