DP6/DP8 of the Path Registry (BRAINY-PROD-LATENCY-TRIAD, the proven flicker mechanism): update paths staged RemoveFromVectorIndex then AddToVectorIndex as two separately-awaited transaction ops — between them a live row was in NEITHER index (dark to semantic recall, fine in metadata list). The native pair widened that window to seconds in production before their side's visibility-commit fix; the structural cure lands here: - hnswIndex.updateItem: absent → add; SAME vector → pure no-op (the production shape — a type-only update re-indexed an unchanged vector, remove+add did pure damage); changed vector → the node NEVER leaves the index: synchronous vector swap first (every query from that instant sees correct distances), then unlink/relink at the node's existing level via shared internals (linkNode/unlinkNodeEdges refactored out of add/remove; entry point and maxLevel provably unchanged). - ReplaceInVectorIndexOperation: ONE transaction leg; feature-detects provider updateItem (native seam flagged — their side ships updateItem, then the adjacent remove+add fallback is dead code). Both update staging sites swapped; delete sites untouched. - LAZY-OPEN GATE (fleet adoption find, SELF-ENGINE-PAIR-STANDARD): under disableAutoRebuild, ensureIndexesLoaded assessed ONLY the vector index — a not-ready native METADATA provider never blocked the completion latch and every find() silently returned [] on a populated store. All three providers now vote; any not-ready report falls through to the rebuild. - docs/path-registry.md: brainy's twin table for the 32 shared path IDs — service class, budgets, lifecycle, narration, and the cited pin per row; owed rows named (LC4 doors-open migration, MT4 yielding heals, LC7 downgrade contract) per the lifecycle-sprint choreography. Pins: update-item-atomic 9/9 (visibility-atomic swap, reverse-index parity vs fresh rebuild, entry-point invariants) · lazy-notready-honor 2/2. Gates: unit 1928/1928 (148 files) · integration 760 · conformance 27/27. |
