Headline change: native HNSW search actually works again. The previous
NativeHnswBackend wrapped @ruvector/router 0.1.28's VectorDb, which a
fresh investigation found to have four serious bugs:
1. HNSW search returned essentially random results — recall@10 ≈ 0%
on the project's FNV fixture and 10% on textbook unit-Gaussian
random vectors. The graph walk could not find self-vectors when
querying with a stored vector.
2. The VectorDb constructor unconditionally wrote a vectors.db redb
file to the user's project root, polluting CWD with multi-MB
files outside .agentic-qe/, in a non-SQLite format that no AQE
migration or backup tooling knew about.
3. Process-wide singleton lock — only ONE VectorDb instance could
exist per process. Subsequent constructors threw "Database error:
Database already open. Cannot acquire lock."
4. NAPI dispose did not synchronously release the redb lock — root
cause of v3.9.5's futex deadlock.
NativeHnswBackend was rewritten to wrap hnswlib-node@^3.0.0 (the
canonical Yury Malkov C++ Hnswlib reference implementation, used by
Pinecone, Weaviate, Qdrant, LangChain, ChromaDB). All four bugs are
gone in one swap. Empirical verification: 100% recall@10 vs the old
10%, faster inserts, multiple instances coexist, no CWD pollution.
useNativeHNSW default is flipped back from false to true (reverting
the v3.9.5 hotfix). Users with large codebases get sublinear HNSW
search by default again.
aqe init now warns when it detects a stale `vectors.db` from the
previous version and suggests `rm vectors.db`. It does NOT auto-delete
(per the data protection rules).
No new dependency was added — hnswlib-node was already in package.json.
Bumps fleetVersion in skills-manifest.json from 3.9.2 (stale) to
3.9.6 to match.
Adds release notes at docs/releases/v3.9.6.md and updates the
release index.
Closes#399. Closes#396 (test-suite cleanup carried over from the
closed PR #403, also in this release).

Documents the four @ruvector/router 0.1.28 bugs found during the
issue #399 investigation, the empirical verification numbers
showing hnswlib-node fixes all four, the rejected alternatives
(wait for upstream, tune efSearch, brute-force, hybrid threshold),
and the user migration guide for stale vectors.db files.
Includes a comparison table:
- Recall@10 (1k vectors, default params): 10% → 100%
- Self-vector found in top-10: NO → YES
- Auto-creates files in CWD: YES → NO
- Multiple instances per process: NO → YES
- Dispose releases resources: NO → YES (immediate JS-side null)
- Native filter functions: NO → YES
- Runtime efSearch tuning: NO → YES
- Resize past initial capacity: NO → YES
- Insert latency (1k × 384 dim): ~430ms → ~324ms
Cross-references the diagnostic scripts in `scripts/diagnose-issue-399*.mjs`
that reproduce each bug and verify hnswlib-node's correctness on
the same fixtures.
CHANGELOG.md gets a new [Unreleased] section describing the migration,
the removed CWD pollution, and the added test infrastructure. The
release manager will rename [Unreleased] to the next version at
release time.

ROOT CAUSE FOUND for the ruview / ruview_live.py hang.
Investigation
-------------
v3.9.4's per-file log gave the user the exact stalling file:
examples/ruview_live.py from the public RuView project. I downloaded
the file (28 KB, 776 lines, 95 entities — normal-shaped Python),
reproduced the hang locally against v3.9.4, then dumped kernel
state of the hung process via /proc/<pid>/wchan and strace.
Findings:
Main thread: futex(0x3c6ded50, FUTEX_WAIT_PRIVATE, 1, NULL)
(NULL timeout = wait forever)
17 total threads:
- MainThread (blocked in futex)
- V8Worker × 4 (blocked in futex)
- DelayedTaskScheduler (epoll_wait — normal libuv)
- SignalInspector (blocked in futex)
- tokio-runtime-w × 6 (blocked in futex)
- libuv-worker × 4 (blocked in futex)
Native modules loaded:
- ruvector-router.linux-arm64-gnu.node
- ruvector-gnn.linux-arm64-gnu.node
- better_sqlite3.node
The deadlock is reproducible: every run against this file produces
the same futex_wait_queue state. After 7 successful VectorDb.insert()
calls (7 rows visible in the vectors table), the 8th never returns.
This is a futex deadlock inside the @ruvector/router native NAPI
module, triggered by VectorDb.insert() against certain vector content
shapes. The Rust tokio runtime threads inside the module hold a lock
the main thread is waiting for, and never release it. The setTimeout-
based watchdog v3.9.3 added cannot interrupt this — setTimeout
callbacks queue between event loop iterations and the event loop is
frozen inside a kernel futex syscall. That's a Node.js architectural
limitation, not a bug in our watchdog code.
The fix
-------
One-line change: useNativeHNSW feature flag default flipped from
true to false in src/integrations/ruvector/feature-flags.ts. All
HNSW operations now route through ProgressiveHnswBackend instead of
NativeHnswBackend. The native module is still loaded and still
available to anyone who explicitly opts in via
setRuVectorFeatureFlags({ useNativeHNSW: true }) — the default path
just no longer touches the deadlock-prone code.
Why this isn't a regression
---------------------------
ProgressiveHnswBackend was already updated in v3.9.3 commit 2bd601b0
to use brute-force exact cosine for the cosine metric. For AQE's
typical KG sizes (<10k vectors @ 384 dim), brute-force cosine is
*faster* than HNSW because it skips the per-query graph-walk
overhead:
1k vectors: brute-force ~0.4 ms vs native HNSW ~0.8 ms (BF wins)
10k vectors: brute-force ~4 ms vs native HNSW ~1.5 ms (HNSW wins)
100k vectors: brute-force ~40 ms vs native HNSW ~3 ms (HNSW wins)
For workloads AQE actually runs in production, brute-force is
faster. Native HNSW only matters above ~10k vectors, which is rare.
And critically, brute-force cannot deadlock — it's a deterministic
loop in pure JS.
Verification
------------
- examples/ruview_live.py: was deadlock, now 258 ms / 95 entries / exit 0
- 200-file synthetic fixture: 1761 ms / 2600 entries / exit 0
- 1-file empty fixture: 380 ms total init / exit 0
- HNSW + memory + init test suites: 152/152 + 452/452 = 604/604 pass
Test updates: native-hnsw-backend.test.ts had three tests asserting
the OLD `useNativeHNSW: true` default. Updated to assert the new
`false` default with a comment explaining v3.9.5's reasoning so
future contributors understand why the flag was flipped.
What's still v3.9.6 scope (#401)
---------------------------------
The architectural fix — running phase 06 inside a killable
worker_threads.Worker so any future native deadlock can be
terminated by the parent — remains tracked in #401. v3.9.5
disables the deadlock-prone path; v3.9.6 will make the watchdog
actually effective for any native code regardless of the underlying
library. Both layers are needed for long-term reliability. The
verification gap that allowed v3.9.3 to ship (no real-world
fixtures, no watchdog effectiveness test, no post-publish canary)
is also tracked in #401 with concrete release-gate changes that
will land alongside v3.9.6.
What we kept from v3.9.4
------------------------
- AQE_SKIP_CODE_INDEX env var + --skip-code-index flag (kept as
user-facing emergency overrides for any future native-layer issue)
- Per-file progress logging in phase 06 (diagnostic transparency)
- Governance / kiro / sync installer findPackageRoot walk-up fixes
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Same-day hotfix for two issues v3.9.3 did not catch:
1. Governance phase failing on chunked bundles (cf-devpod).
2. Phase 06 hang on codespaces (ruview) — watchdog unable to
interrupt synchronous native code blocking the event loop.
v3.9.4 ships:
- Fix C: findPackageRoot() walk-up for governance/kiro/sync
installers — repairs the chunk-split regression class of bugs.
- Fix A: AQE_SKIP_CODE_INDEX env var + --skip-code-index flag —
escape hatch for the phase 06 stall until the proper killable-
worker fix lands in v3.9.5.
- Fix B: Per-file progress logging — exposes the exact file the
indexer is processing when a stall happens, providing the
diagnostic evidence needed for a targeted fix.
The proper fix for the phase 06 stall (running the indexer in a
killable worker_thread or child_process.fork) is deferred to
v3.9.5 and tracked in a separate issue. v3.9.4 is a unblock-first
release, not an architectural change.
All v3.9.1 feature benefits (RVF pattern store, unified HNSW,
agent memory branching, KG semantic search) remain enabled.
Local verification: 440/440 init + kernel + optimizer unit tests
pass. Build + typecheck clean. Three real fixture runs confirm
the escape hatch works, per-file logging works, and governance
phase succeeds with asterisk.

Version bump and release docs for the 5-fix init reliability release.
v3.9.3 addresses the remaining root causes the v3.9.2 hotfix did not
cover:
Fix 1: HnswAdapter dispose() plumbing for test/shutdown paths.
Fix 2: Lazy TokenOptimizerService — no more bootstrap noise at
CLI startup. CLI commands that don't use the token optimizer
no longer open patterns.rvf or memory.db.
Fix 3: Phase 10 no longer spawns the MCP daemon — the spawn was
racing the parent for file locks and producing cosmetic
error spam. Claude Code starts MCP on demand via .mcp.json.
Fix 4: findMcpEntry() works with esbuild code-split chunks
(regression of v3.7.10 fix introduced in v3.9.0).
Fix 5: Phase 06 now has a 30 s per-file and 180 s whole-phase
watchdog with progress logs every 100 files. KG semantic
search and vector embeddings remain fully enabled.
All v3.9.1 feature flags (useRVFPatternStore, useUnifiedHnsw,
useAgentMemoryBranching) remain true — this release preserves the
v3.9.1 benefits and fixes the rollout bugs.
User-perspective verification (all passing):
Empty fresh project: 427 ms exit 0
200-file fixture: 672 ms with progress logs
15k-entity heavy fixture: 3120 ms exit 0
Pre-existing .agentic-qe + aqe --version: 1 line "3.9.3"
aqe mcp --help: exits 0 with usage text
Targeted test results:
token-optimizer-service: 17/17
HNSW (native/legacy/unification): 99/99
unified-memory: 53/53
pattern-store / rvf-pattern-store: 65/65
init/orchestrator + init/phases/database-phase: 32/32
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Two related fixes for the init flow broken in v3.9.1:
1. aqe init --auto hangs at "Code intelligence pre-scan"
After v3.9.1 flipped useRVFPatternStore to true by default,
AQELearningEngine.initialize() would open patterns.rvf twice in
the same process:
a) createPatternStore() -> _createRvfStore('.agentic-qe/patterns.rvf')
acquires an exclusive native file lock via @ruvector/rvf-node
b) getSharedRvfDualWriter() -> getSharedRvfAdapter() ->
createRvfStore('.agentic-qe/patterns.rvf') tries to acquire the
same exclusive lock -> deadlocks forever
Fix: createPatternStore() now routes through the getSharedRvfAdapter()
singleton. Only one file handle exists per process; subsequent callers
receive the cached instance. RvfPatternStore.dispose() gains a
skipCloseOnDispose option so it won't close a shared adapter.
2. CLI doesn't exit after init completes
Native NAPI handles from @ruvector/rvf-node and @ruvector/router
kept the event loop alive indefinitely. cleanupAndExit() previously
used async dynamic imports for cleanup modules, which loaded more
native bindings before the unref'd 3s force-exit timer could fire.
Fix: cleanupAndExit() is now synchronous — fire-and-forget disposes
followed by immediate process.exit(). Init completes and exits
cleanly in ~7s.
Verification:
- aqe init --auto on fresh project: EXIT=0, ~7s, all 12 phases pass
- Isolated npm pack+install: aqe --version returns 3.9.2
- 65 pattern-store + rvf-pattern-store tests pass
- 15/15 performance gates pass
- Build + typecheck: zero errors
Note: Full unit suite runtime regression (>22min, unrelated to this
fix) tracked separately in #396.

* feat: implement ADR-062 (StrongDM all 3 tiers) and ADR-087 (RuVector 14/14 capabilities)
ADR-062 StrongDM Software Factory — all 6 actions across 3 tiers:
- Tier 1: Loop detection wired to MCP protocol-server (blocks on strike 3+),
token dashboard (pre-existing)
- Tier 2: Holdout testing (10% FNV-1a selection, filtered in test-execution),
gate ratcheting (monotonic 5-pass/2%/95% cap, persisted to MemoryBackend)
- Tier 3: Progressive context (TF-IDF prediction, reduces availableFiles on spawn),
meta-learning cycle (4 insight types, stored + published as domain events)
ADR-087 RuVector Advanced Capabilities — milestones 1-5:
- EWC++ recordOutcome + backgroundConsolidate wired to 3 domain coordinators
- R1: HDC fingerprinting (10K-bit hypervectors, wired to PatternStore.store())
- R3: Delta event sourcing (sparse encoding, wired to PatternStore.store())
- R13: Cognitive routing (predictive compression, wired to mailbox.send/receive)
- R14: Hyperbolic HNSW (Poincare ball, auto-indexed in PatternStore.store())
Also updates ADR statuses: 059, 060, 061 → Implemented (were already done),
062 → Implemented, 086 → In Progress, 087 → Implemented.
223 new tests across 11 test files, all passing. Zero regressions.

* feat: implement RVF cluster (ADR-065/066/067/071) with native benchmarks
Implements the RVF persistence cluster for persistent HNSW vector storage,
agent memory branching, and HNSW unification foundation.
Key changes:
- RvfPatternStore: IPatternStore backed by @ruvector/rvf-node native HNSW
(1.2ms cold-start, 0.19ms search p50, verified with real native binary)
- AgentMemoryBranch: per-agent COW isolation via derive(), ingest-log merge,
wired into Kernel.initialize() + DefaultAgentCoordinator
- HnswLegacyBridge: adapts old IHNSWIndex to unified IHnswIndexProvider,
wired into PatternStore when useUnifiedHnsw flag enabled
- Factory routing: createPatternStore() returns RvfPatternStore when flag
enabled + native available + data directory exists
- Dream engine: accepts external RVF adapter (no duplicate file handles),
RVCOWBranchManager enhanced with recall validation check
- @ruvector/gnn bumped 0.1.19→0.1.25, 3 new feature flags added
- IPatternStore interface extracted for polymorphic pattern store usage
- 50 new tests (16 RvfPatternStore + 17 AgentMemoryBranch + 12 bridge + 5 benchmarks)
- 1188 tests pass, 0 regressions
ADR status: 066 Implemented, 067 Implemented, 065 Implemented,
069/071 In Progress (honest assessment after brutal-honesty review)

* fix(init): resolve skills/agents paths from package root, not relative to bundle depth
esbuild code-splitting puts installer code into dist/cli/chunks/ (3 levels
deep) instead of dist/init/ (2 levels deep), so the old ../../ traversals
landed at dist/ instead of the package root — causing "Source directory not
found" errors for all global installs.
Replace brittle relative-path resolution in all 4 installers with a shared
findPackageRoot() that walks up to the nearest package.json with
name=agentic-qe. Prioritise assets/ paths (canonical npm source) over
.claude/ paths.

* feat: complete RVF cluster Phases 2-3 (ADR-067/069/071/072) with devil's advocate fixes
Phase 2A (ADR-067): Agent memory branching enabled — useAgentMemoryBranching=true,
BRANCH_DISCARD witness action, recordIngest callback exposed to agents via config.
Phase 2B (ADR-069): Dream RVF COW — useRvfFork driven by isRVFPatternStoreEnabled(),
child adapter stored + temp files cleaned up on merge/discard, 13 tests.
Phase 2C (ADR-071): HNSW unification — useUnifiedHnsw=true, HNSWEmbeddingIndex routes
through HnswAdapter, UnifiedMemory vectorIndex uses UnifiedHnswIndex, HnswLegacyBridge
delegates to adapter string-ID APIs (no duplicate ID maps), addEmbeddingsBatch routed
correctly, saveIndex/loadIndex safe under unified mode.
Phase 3 (ADR-072): RVF primary migration scaffolding — RvfMigrationAdapter (5-stage
routing with write latency tracking), RvfConsistencyValidator (rolling divergence +
compaction), RvfStageGate (go/no-go with witness chain), rvfMigrationStage=1 default,
wired into shared-rvf-dual-writer at stage >= 2, 32 tests.
Cross-cutting fixes from devil's advocate review:
- Shared RVF adapter singleton eliminates dual file handles (kernel + dream engine)
- RvfPatternStore reports honest nativeAvailable=false + rvfInitError on failure
- ESM-safe dynamic import() replaces require() in dream-engine and branch-manager
- quality_assess defaults to src/ instead of cwd to prevent full-project scan hang
- discoverSourceFiles skips .agentic-qe/.claude/.cache dirs, adds maxFiles=5000 cap

* feat: complete RVF cluster plan — Phase 2C decommission, Phase 3 integration, fix 7 pre-existing test failures
Phase 2C (ADR-071) — HNSW decommission:
- Remove RuvectorFlatIndex fallback from unified-memory.ts; always use UnifiedHnswIndex
- Hardcode isUnifiedHnswActive()=true in HNSWEmbeddingIndex (hnswlib-node legacy path is dead code)
- Create HnswShadowValidator for brute-force vs HnswAdapter divergence validation
- Benchmark alias (rvf-pattern-store.bench.ts) for plan compliance
Phase 3 (ADR-072) — RVF Primary Migration integration:
- RvfMigrationCoordinator: wires adapter + validator + gate with real SQLite/RVF handles
- MCP tools: migration_status, migration_check, migration_promote (persistence category)
- Kernel boot wiring: coordinator initializes when rvfMigrationStage >= 2
- RvfMigrationAdapter.setStage(): propagate promotions to routing logic
- Promote default rvfMigrationStage from 1 (hybrid) to 2 (dual-write-sqlite-primary)
- Integration test: 13 tests covering full lifecycle (stage 1→2→3→4), write/read routing,
consistency checks, gate enforcement, fallback, metrics
Test fixes (7 pre-existing failures → 1 remaining):
- code-intelligence-metrics-wiring: spy console.info not console.log (logger routes to console.info)
- mcp-integration: disable ADR-062 loop detection (repeated identical calls are by design)
- dream-cycle-tool (2 tests): RvfPatternStore empty-query branch returns all patterns from SQLite
- coherence-integration (4 tests): RvfPatternStore vector search fallback computes brute-force
cosine over SQLite embeddings when RVF adapter unavailable; getStats() falls back to SQLite count;
auto-attach SQLitePatternStore in initialize() when not explicitly wired

* chore(release): bump version to v3.9.1
- Version bump in package.json and skills-manifest.json
- Fix "Dynamic require of X is not supported" in ESM bundles by adding
createRequire banner to both CLI and MCP build scripts — every chunk

* fix(ci): regenerate package-lock.json for npm ci compatibility
The lock file was out of sync with package.json — new transitive
dependencies added on main were missing. All 15 CI checks failed
at `npm ci` with "Missing from lock file" errors.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(ci): pin Node to 24.13.0 and restore working lock file
Node 24.14.1 ships npm 11.11.0 which enforces stricter lock file
validation than 11.6.x (what 24.13.0 ships). The existing lock file
passes under 11.6.x but fails under 11.11.0 with "Missing from lock
file" for transitive dependencies of private-registry packages.
Pin all 5 workflow files to node-version: '24.13.0' and restore the
lock file from commit f9b76968 (last CI-passing state) with only the
version bump to 3.9.1.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(ci): regenerate package-lock.json with npm 10 for stable npm ci
npm 11 (Node 24) produces internally inconsistent lock files that npm ci
rejects — each npm install resolves transitive deps differently. Generated
with npm 10 (Node 22 LTS) which produces stable lock files compatible with
both npm 10 and npm 11.

- Delete dead MCP server.ts (911 lines, never used in production — entry.ts
imports MCPProtocolServer). Add legacy aliases in index.ts for backwards compat.
- Fix ESLint: rename .eslintrc.js to .eslintrc.cjs (CommonJS in ESM project)
- Fix hardcoded version '3.0.0' in protocol-server.ts and http-server.ts —
now reads dynamically from package.json
- Fix vitest process hang: add worker-level afterAll force-exit (setup-worker.ts)
and global teardown safety net. Native modules (better-sqlite3, hnswlib-node)
held open handles preventing fork worker exit.
- Add test gate to npm-publish.yml — 194 unit test files must pass before publish
- Disable benchmark.yml release trigger (benchmarks/suite.ts doesn't exist)
- Remove continue-on-error from test steps in optimized-ci.yml (was masking failures)
- Add getToolDefinitions() to MCPProtocolServer for test introspection
- Update e2e and integration tests to use production server API

Based on Anthropic's "Lessons from Building Claude Code: How We Use Skills" article.
Transforms QE skills from flat knowledge cards into folder-based systems with
gotchas, progressive disclosure, composition, config, hooks, and run history.
Changes across all 4 phases:
- Add Gotchas sections to 30 skills with battle-tested failure data from Nagual/memory.db
- Rewrite all 84 skill descriptions as "Use when..." trigger conditions

All new RuVector capabilities (native HNSW, neural routing, coherence
gates, transfer learning, etc.) now ship enabled so users get immediate
value on upgrade. Users can disable individual features via CLI or
setRuVectorFeatureFlags() for opt-out.
Update 11 test files to match new defaults.

Upgrade from v3.7.23 to v3.8.0 — this is a minor version bump
reflecting the scope of the RuVector integration (23 tasks, 4 phases).
Regenerate package-lock.json from scratch to fix npm ci failures
caused by stale transitive dependency entries (agentic-flow@2.0.7
referenced packages not in the lock file).

Add three subsystems for fleet orchestration intelligence:
- Pre-spawn MCP validation scans agent files for tool references and
validates availability at install and spawn time (advisory only)
- Agent dependency graph with YAML frontmatter parsing, topological
sort, and phased spawn plans for multi-agent orchestration
- Co-execution repository tracks agent pair success rates, feeding
behavioral signals into the signal merger for routing decisions
Wire all subsystems into the queen coordinator: dependency graph built
on initialize(), MCP validation in requestAgentSpawn(), co-execution
recording in handleTaskCompletionCallback(), and getSpawnPlan()/
getDependencyGraph() exposed on the public interface.
Add structured dependencies frontmatter to 5 agent definitions and
475 passing tests including 7 end-to-end integration tests proving
the wiring works.
Closes#342

preserveOverridesDir() used __dirname (undefined in ESM bundles), causing
a TypeError that crashed the agents installer. Skills were installed but
agents were silently skipped. Fixed by using import.meta.url resolution
with try/catch fallback. Also wrapped agents installer in try/catch in
the assets phase so one failure doesn't crash the entire phase.

Tier 3 baseline instrumentation and critical fix for test-induced
production database deletion. Tests using relative '.agentic-qe/memory.db'
paths were deleting the production DB during cleanup — now all test DB
paths use os.tmpdir(). Also fixes resetUnifiedMemory() cache leak and
process.cwd() bypasses in pull-agent and brain-handler.
