Overview

Command: Reconcile counted-not-stored storm events onto ErrorLog rows and maintain the storm_events episode record.

Runs in a background job (DB allowed). For each counted fingerprint:

1. Recompute the canonical error_hash from the stored identity parts
   (the gate's key deliberately omits application_id — resolved here)
2. Unresolved match  → single UPDATE: occurrence_count += N
3. Resolved match    → reopen (mirrors FindOrIncrementError semantics)
4. No match          → create a minimal ErrorLog from the exemplar

Counts are exact. Notifications are NOT dispatched from here — during a storm they’re suppressed by design; the storm notification covers it.
