Two release-blocking findings from the durability kill-matrix, both fixed in the owning layer: 1. LOG-AUTHORITY REPLAY AT OPEN: durable-at-ack fsynced the fact before the ack, but open() truncated every fact above the manifest — after a power loss that takes the un-fsynced tmp+rename canonical bytes, the acked write's ONLY durable copy was discarded. Now: under 'log' authority, open() REPLAYS intact facts above the manifest into canonical (FactLog.peekFactsAbove — CRC-gated, order-sorted) and advances the manifest to cover them; tree-authority brains keep the truncate contract they were promised. Pinned end to end: the power-loss row constructs the exact disk state (fsynced log, vanished canonical rename) and the acked write lives. 2. NO SILENT COMMIT: commitSingleOp buffered the generation BEFORE the fact append; an append failure (ENOSPC) rejected the caller but the next flush durably committed the generation with NO fact — a permanent silent log gap. Now the failure path un-buffers and returns the counter reservation: nothing commits, the log stays gap-free, and the canonical execute-residue orphan is the documented crash-equivalent. Plus: the kill-matrix itself (11 rows — every commit-path fault point × reopen-as-crash recovery contract, at-ack variants, disk-full row; five new zero-cost faultPoint sites), the log-authority pin suite (oracle green/red/state-differs, flip refusal, switch survives reopen, 9/9), and the group-commit covering pins (5/5).
