Convergent findings (≥2 reviewers): NONE. - Kimi BLOCK (materializer main.go exits 0 on validation fail): confabulation. Code does os.Exit(1) at lines 65-66. - Qwen BLOCK (saveTask race condition): confabulation. All access to inflight/pending is under s.mu. - Qwen WARN (saveAfter nil deref): confabulation. Explicit `if h.persist == nil { return }` guard at line 184. - Opus BLOCK (TestSaveTask_Coalesces): self-withdrawn in same response. Opus WARNs actioned: - Detached docstring on TestAdd_SmallIndex_ConcurrentDistinctIDs — attached. - isoDatePartition fallback comment — clarified as defense-in-depth (MaterializeAll guards upstream; branch unreachable through public surface). Disposition + verdicts in reports/scrum/_evidence/2026-05-02/. Pattern matches feedback_cross_lineage_review.md: only Opus emits BLOCK-class findings worth verifying; Kimi/Qwen single-reviewer BLOCKs failed trace verification.

Initial recover() guard caught panics but returned errors at the same rate. **Real fix**: lift the source-of-truth out of coder/hnsw — `i.vectors map[string][]float32` side store maintained alongside the graph, panic-safe `safeGraphAdd`/`safeGraphDelete` wrappers, `rebuildGraphLocked` reads from `i.vectors` (independent of graph state), warm-path Add falls back to rebuild on panic.

The panic fix exposed a second bottleneck: every successful Add called `Persistor.Save` synchronously, which takes the index RLock for `Encode` (~6MB JSON for 1942-entry × 768d) — blocking concurrent Add Lock acquisitions. 5min sustained run showed playbook scenario p50 climbing 551ms→1398ms as the index grew. **Fix**: `saveTask` per-index single-flight coalescer in `cmd/vectord/main.go` — `saveAfter` now triggers an async save; concurrent triggers during an in-flight save mark "pending" so N triggers collapse into ≤2 actual saves. RPO trade: Add returns OK before save completes (~1 save's worth of crash-loss exposure; same fail-open posture as ADR-005).
