THE DEFAULT FLIP (ruled on proven evidence — at-ack survived 301/301 acked-writes-through-power-cut in block-layer fault injection; deferred tree authority demonstrably loses flush-covered acks): a brain with NO stored authority artifact now ADOPTS LOG AUTHORITY AT OPEN. The oracle gates the flip exactly as the guarded adoption path always did — curable divergences baseline-backfilled, the flip lands ONLY on a green verdict — and a brain that cannot verify STAYS tree-authoritative loudly, with the refusal recorded on the switch artifact so subsequent opens are cheap. config logAuthority: 'defer' is the explicit documented opt-out (no automatic adoption; declared flush-window loss; adoptLogAuthority() flips later). A stored artifact always wins. RELEASES.md carries the posture. Two standing .fails debt pins FLIP TO HOLDING under the default: the at-ack crash-survival gap and the ack-at-log durability target — both now permanent asserted truths, not aspirations. POWER-CUT THROW SITES (fault-injection findings, brainy-alone config): - A manifest-listed-but-unloadable column segment QUARANTINES at discovery (loud once, counted always, quarantinedSegments() exposed for the heal) and the field serves its remaining segments DEGRADED — never a raw throw killing every query on the field. Real storage faults still propagate untouched. - Torn generation artifacts (NaN/garbage in manifest or counter) DISCARD with narration at the store's open and recovery re-derives — plus a defensive finite-integer guard at the init consumer. Never a RangeError killing an open. THE LOUD TORN-RECORD CONTRACT: an existing-but-unparseable stored record now surfaces as a typed, counted TornRecordError on every entity-read surface (including fifteen previously-blind per-item batch catches); ENOENT stays clean-absent; artifact readers with designed absent-recovery keep null-tolerance behind the loud floor. Disk corruption can no longer read as silent data invisibility. Suite migration: the default's pins inverted deliberately, generation baselines made relative, quarantine-contract pins rewritten to the ruled behavior. Gates: tsc 0 · unit 2065/2065 (159 files) · integration 826 (93 files) · conformance 31/31 · kill-matrix 15/15 · torn-open guards 2/2. |
