+-- Drop the local Songstats quota ledger (recoupable/chat#1797, bullet 2).
+--
+-- The ledger mirrored Songstats' rate quota locally so a budget gate could halt
+-- the backfill drain before spending. In practice it drifted: the prod 429 storm
+-- (2026-06) filled it with phantom 429 "hits" (insert-on-every-call, success or
+-- not), so the gate tripped on rate-limit noise, not real quota — a premature
+-- drain halt. Songstats is the rate authority; api now relies on per-track
+-- bounded exponential backoff and defers rate-limited rows to the next run
+-- instead of mirroring a quota.
+--
+-- Code references removed in api PR #674 (getBackfillBudgetStep,
+-- insertSongstatsQuotaLedger, selectSongstatsQuotaSpent and their tests).
+-- Created 20260610010000_create_playcount_measurement_store.sql.
+-- CASCADE cleans up the table's indexes, RLS, and FKs.
