 /**
- * vector-backfill.ts — one-time per-mind vector repair + chunk backfill
- * (D1 follow-up, 2026-06-12).
+ * Bounded vector + chunk reconciliation for frames written by fast hook paths.
  *
- * Two problems this fixes for EXISTING minds:
- *  1. Mock-fingerprinted vectors: minds whose frames were indexed while only
- *     the mock embedder was available carry NOISE vectors that look indexed
- *     (the boot reconcile only fixes COUNT mismatches, not content) — the
- *     D1 probe found the real personal mind in exactly this state. When a
- *     real embedder is active, recreate the vec tables and re-embed.
- *  2. Chunk backfill: chunk-level retrieval (default-ON since the D1 probe:
- *     hit@5 46/52 vs 17/52) only helps frames that HAVE chunks. New frames
- *     chunk-index on write; pre-existing frames need this one-time
- *     `rechunkAllFrames` pass. Un-backfilled minds degrade gracefully
- *     (whole-frame fallback) until this runs.
- *
- * Idempotent via a `meta` flag; never throws (callers are boot/cron paths).
- * Skips entirely while the embedder is mock — the flag stays unset so the
- * next run (daily cron) retries once a real provider activates.
+ * The legacy `vector_backfill_v1` marker records only the destructive
+ * mock-fingerprint rebuild. It never suppresses incremental reconciliation:
+ * hook writes intentionally persist frame/FTS data first and this pass repairs
+ * missing semantic indexes shortly afterwards.
