Phase 5 UAT discovered the helper scripts surfaced missing-vibium as
`actual: "eval error: vibium binary not found..."` inside a `failed`
envelope. The Fallback Policy in SKILL.md said scripts MUST return
status:"skipped" with reason "browser-engine-unavailable" — that
contract was aspirational. F1 makes it real.
Contract changes:
- lib/vibium.js: ENOENT now throws typed VibiumUnavailableError (with
stable code:"BROWSER_ENGINE_UNAVAILABLE" for cross-module duck typing)
- New helper unavailableEnvelope() returns canonical skipped envelope
with top-level vibiumUnavailable:true and output.reason field
- New runOrSkip() wraps each helper's main() and converts the typed
error into the documented envelope on the way out
- New rethrowIfUnavailable() helper used inside per-script catch blocks
so missing-vibium bubbles past local "convert exception to fail()"
handlers — assert.runConsoleCheck/runNetworkCheck/runBrowserSideCheck,
batch's per-step catch, check-injection main, intent-score main,
visual-diff main all updated
- emit() now returns exit code 2 for status:"skipped" (was 1)
- Exit code contract documented: 0=success, 1=failed, 2=skipped
Downstream skills can now branch on result.vibiumUnavailable === true
or exit code === 2 instead of grepping the actual string for
"vibium binary not found".
Tests: 103 (was 86). New file qe-browser-unavailable-e2e.test.ts spawns
each of the 5 helpers under PATH=/tmp/fake-bin (node only, no vibium)
and asserts exit 2 + skipped envelope shape. vibium-lib test grew from
10 to 22 cases including VibiumUnavailableError, runOrSkip, exit codes.
Smoke test: 10/10 PASS (was 9/9). New tc011 builds a fake bin dir
inside the smoke test work dir and verifies the contract end-to-end
against the actual installed scripts.
SKILL.md updated:
- Output Contract section now documents all 3 statuses with shapes
and exit codes
- Fallback Policy replaced generic prose with concrete bash + Node
snippets that branch on the structured field
ADR-091 Phase 6 documents the change and verification.

Ran fresh `aqe init --auto` against an empty test project at
/tmp/qe-browser-uat and exercised every helper script as a real user.
12 checks documented in ADR-091, all passing:
1. qe-browser skill installed cleanly
2. navigate + assert end-to-end against httpbin.org
3. M5 --threshold=0.42 form parsed live (verified non-default value)
4. M6 batch pre-validation aborts BEFORE side effects
5. M7 intent-score returns scored candidates from real form
6. M4+M8 check-injection --exclude-selector strips body (3595→35 chars)
7. M2 fixture server binds 127.0.0.1 (verified via banner)
8. M3 path traversal blocked (HTTP 404 on /etc/passwd.html)
9. Vibium-missing fallback returns clear actionable error
10. Installed smoke-test.sh: 9/9 PASS from inside test project
11. Idempotent re-init: Browser engine line still printed
12. JSON envelope contract validated on every emit
H6 pre-flight short-circuit confirmed in production:
"Browser engine: vibium 26.3.18 (already installed)"
The "this can take 1-3 minutes" banner is suppressed when vibium is
already on PATH, matching the documented Phase 2 behavior.
New finding logged as F1 (NOT a Phase 4 regression):
Helper scripts surface missing-vibium as `actual: "eval error: ..."`
inside a `failed` envelope. The SKILL.md Fallback Policy says
downstream skills should report status:"skipped" reason:
"browser-engine-unavailable". A cleaner contract would be a
top-level vibiumUnavailable:true flag. Not a blocker.

M1 visual-diff threshold: documented "max difference fraction" convention
matching Playwright maxDiffPixelRatio (was inconsistent in docs/code).
M2 fixture server bind: default to 127.0.0.1 instead of 0.0.0.0;
QE_BROWSER_FIXTURE_HOST=0.0.0.0 opt-in for explicit external access.
Codespaces auto-forwards 0.0.0.0 ports — this was an unintentional open
server every time the eval ran.
M3 path-traversal guard: replaced startsWith() with path.relative() +
'..'/absolute check. The old guard false-passed sibling-prefix dirs
(/foo vs /foo2) and was fragile on Windows mixed separators.
M4 ANSI escape injection: added sanitizeSnippet() that strips C0 controls
(0x00-0x1F except \t\n) and DEL (0x7F) from every check-injection
finding snippet. Prevents `cat findings.json` from triggering terminal
control sequences embedded in malicious page content.
M5 parseArgs --key=value: split on first '=' so --threshold=0.05 works
alongside --threshold 0.05. Only the first '=' is split so URL/base64
values survive intact.
M6 batch.js pre-validation: added validateAllSteps() that walks every
step's required fields BEFORE the first vibium call. Step 17 typo now
aborts before steps 1-16 execute their side effects.
M7 intent-score bare-x regex: anchored \bx\b in close_dialog scorer so
"fix", "exit", "extra", "sixteen" no longer match. Unicode × and ✕
unchanged.
M8 check-injection --exclude-selector: new flag drops subtrees from
the scan. Page text is read from a CLONE of <body> with matching
elements removed — live page unchanged. Lets docs sites scan their
own pages without self-flagging documentation about prompt injection.
M9 09-assets vibium catch: wrapped raw error with actionable recovery
guidance (`npm install -g vibium`, then re-run `aqe init`).
Hidden bug found and fixed during M2/M3 testing: fixtures/serve-skills.js
existed but had never been run because the repo root is ESM and the file
uses CommonJS require(). Added scoped fixtures/package.json with
"type": "commonjs" matching the existing scripts/package.json pattern.
Tests: 86 unit tests across 7 files (was 50). All pass.
Smoke test: 9/9 still passing against real Vibium v26.3.18.

User pushed back on Phase 3 attempt 1 ("blocked on linux-arm64"). After
re-verifying upstream — Vibium 26.3.18 IS the latest on npm, Chrome for
Testing across Stable/Beta/Dev/Canary still ships only linux64 (x86_64),
mac-arm64, mac-x64, win32, win64 — installed Debian's native ARM64
chromium + chromium-driver via apt and symlinked them into Vibium's
cache. Then ran the smoke test for real and found four real bugs in
the qe-browser helper scripts that would have shipped broken.
Bugs found and fixed:
1. Eval contract was wrong. lib/vibium.js's vibiumEvalStdin sent
`console.log(...)` expecting Vibium to capture it. Vibium doesn't —
`eval` returns the LAST EXPRESSION's value as
`{"ok":true,"result":"<stringified>"}`. Fix: dropped console.log
wrappers from assert.js/intent-score.js/check-injection.js; added
unwrapEvalResult() in lib/vibium.js that parses the envelope and
JSON-decodes the result string back into our object.
2. lib/vibium.js did not inject --headless. Vibium defaults to visible
browser, which fails in headless containers with "Missing X server
or $DISPLAY". Fix: lib/vibium.js prepends --headless unless
QE_BROWSER_HEADED=1 is set in the env.
3. `vibium screenshot -o /abs/path/foo.png` ignores the directory and
saves to `~/Pictures/Vibium/foo.png`. Verified live. Fix:
visual-diff.js passes just the basename, reads from Vibium's actual
output dir, copies to the requested path, unlinks the source.
4. `vibium screenshot --selector` flag does NOT exist in v26.3.x.
Verified via `vibium screenshot --help`. Fix: visual-diff.js throws
a clear error with remediation guidance if a caller passes
--selector. (B3's "fall back to eval-clip" comment is now removed.)
Plus a real environment-flakiness fix: smoke-test.sh sets
`vibium viewport 1280 720` before tc006/tc007 visual-diff captures
because httpbin.org/html renders at non-deterministic dimensions
(765x672 vs 780x654 observed) when no viewport is set, causing
spurious pixel-diff failures.
Verbatim smoke test result on this codespace:
Smoke testing against vibium v26.3.18
PASS tc001 url_contains on httpbin form
PASS tc002 selector_visible h1 on httpbin /html
PASS tc003 failing assertion exits 1
PASS tc004 batch 3-step happy path
PASS tc005 batch stops on first failure
PASS tc006 visual-diff baseline created
PASS tc007 visual-diff second run matches
PASS tc008 check-injection clean page
PASS tc010 intent-score submit_form on httpbin form
PASS: 9 FAIL: 0 SKIPPED: 0
Unit tests still pass: 50/50 (one test had to be updated — it asserted
`buildScript` includes 'console.log', which is now correctly NOT in the
script after the eval-contract fix).
Phase 3 verification COMPLETE per ADR-091. The qe-browser helpers work
end-to-end against real Vibium + real Chromium + pinned httpbin.org
fixtures. The Linux ARM64 chromium-symlink workaround is documented in
ADR-091; user-facing docs in references/migration-from-playwright.md
still need updating (marked as Phase 4 follow-up).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Ran the smoke test in this codespace (linux-arm64). Vibium installed
cleanly (v26.3.18) and the H1 detectVibium fix verified against real
binary output. tc003 and tc005 passed (failure-path tests that don't
need a browser). The other 7 tests failed because Google does not
publish chrome-for-testing for linux-arm64; Vibium downloaded the
linux64 (x86_64) variant which dies under Rosetta with an elf-loader
error.
Workarounds attempted and rejected:
- apt install chromium → native ARM64 binary works but Vibium
hardcodes its own cached chromedriver, no --browser-path flag
- searched the binary for VIBIUM_CHROME_PATH / --browser-path /
BROWSER env var support → none in v26.3.18
- System chromium responds at /json/version with CDP, not BiDi;
would need a BiDi-speaking chromedriver to use --connect
Conclusion: Phase 3 verification cannot complete on linux-arm64. This
is a Vibium upstream platform gap, NOT a qe-browser bug. The qe-browser
script-level integration with the real vibium binary IS partially
verified by the 2 passing tests.
Added "Vibium does not support Linux ARM64 today" to the Negative
Consequences section. PR reopen still gated on running smoke-test.sh
on linux-x64 or mac-arm64.

Three correctness blockers identified by qe-devils-advocate review of the
initial qe-browser implementation (PR #420, closed without merge):
B1: intent-score.js String.replace special-char corruption
- SCORER_JS.replace('__SCOPE__', JSON.stringify(scope)) interpreted $&,
$`, $', $1-$9 in the replacement string. Scopes like
div[data-x="$amount"] silently corrupted the generated script.
- Fix: split('__TOKEN__').join(value) for literal substitution.
- Tests: 4 new regression tests covering $&, $', $1, intent placeholder.
B2: assert.js fail-OPEN on console/network telemetry errors
- runConsoleCheck/runNetworkCheck used to return ok:true when
`vibium console --json` failed for any reason. no_console_errors
silently reported pass when telemetry was unavailable.
- Fix: new unavailable() sentinel returns ok:false + unavailable:true.
runCheck surfaces it via a new `unavailable` field. Summary
distinguishes "assertion failed" from "telemetry unavailable".
- Bonus (H5): expected-field uses ?? not || so element_count {count: 0}
reports `expected: 0` instead of `null`.
- Tests: 2 new regression tests on the sentinel + element_count zero.
B3: visual-diff.js dead fallback comment
- Source comment promised "fall back to eval-clip if not present" but
no fallback existed. Direct violation of feedback_no_unverified_failure_modes.
- Fix: comment removed; specific error handler added for unsupported
--selector flag with clear remediation message. No fake fallback —
silently substituting full-page would produce wrong baselines.
Plus: ADR-091 documents the Vibium-as-engine decision with full
rejected-alternatives section (dev-browser, gsd-browser, Playwright MCP,
status quo, build-from-scratch), four implementation phases, and a risks
table tracking the 11 devil's-advocate findings with status. Phase 3
(real Vibium install + smoke test) is explicitly gating PR reopen.
Verification:
- 420/420 tests pass (387 init + 33 qe-browser, 6 new regression tests)
- npm run build: clean
- eslint on touched files: clean
- All 6 helper scripts pass node --check
Branch is intentionally not pushed and PR is intentionally not reopened
until Phase 2 (H1, H2, H4, H6, H7, H8) and Phase 3 (real Vibium smoke
test) are complete.

* 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
now has a working require() for Node.js builtins
- Add CHANGELOG.md entry and release notes for v3.9.1

* 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.

Integrate tree-sitter WASM as the default parser for 5 languages, replacing
regex-only parsing (~97-98%) with AST-based parsing (~100% accuracy).
- Add TreeSitterWASMParser implementing ILanguageParser for 5 languages
- Bundle only needed WASM grammars in assets/grammars/ (8.5MB vs 50MB)
- Add FallbackParser with 3-retry logic before permanent regex degradation
- Add per-call parser instances to prevent concurrency races across await
- Add cyclomatic complexity computation from AST branching nodes
- Add property extraction from class/struct AST nodes
- Add AQE_PARSER_REGEX_ONLY=1 env var for opt-out to regex
- Replace require() with ESM-compatible dynamic import() in registry
- Mark web-tree-sitter as external in CLI/MCP esbuild configs
- Amend ADR-076 with decision rationale and alternatives evaluated
Alternatives evaluated and rejected:
- @ast-grep/napi: npm package only ships JS/TS/CSS/HTML, others need native .so
- node-tree-sitter: requires native C compilation via node-gyp

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.
