v2.1.3

Claude Note 2.1.3 makes index freshness reflect verified saved revisions instead of successful command exits.

• Existing schedulers can use bounded index-refresh begin / finish hooks while retaining their commands, locks and timers.
• Text acknowledgement checks exact active content and FTS rows. Vector acknowledgement also checks the selected model/pipeline, recorded chunk totals and actual finite nonzero vectors.
• Immutable revision references, a canonical index owner, scoped capability receipts and durable completion states prevent stale, mismatched or repeated acknowledgement. Later writes stay dirty.
• Existing refresh and immediate remember indexing use the shared contract. Custom scheduler adoption remains explicit.
• Rust-inspired ownership and validity rules are documented in docs/MEMORY_OWNERSHIP.md.

Validated with 447 isolated Python 3.11 tests and 13 Node contracts using SQLite/vector fixtures (zero skips). The proof covers retained tracked mutations above the recorded legacy baseline. It does not establish historical corpus coverage, semantic truth, historical model-weight bytes or agent task benefit.
