feat: self-optimizing flywheel (ADR-176) + signed RVFA config propagation (ADR-177) — self-learning demonstrated (#2572)
* docs(adr): ADR-176 self-optimizing harness loop (receipt-backed) + ADR-177 signed config propagation ADR-176 — Self-optimizing harness loop, receipt-backed. Closes the loop around metaharness's optimization primitives (honest: real wrappers over optional upstream packages, never run to a measured outcome in-repo, no provenance, no held-out corpus, no feedback path). Design incorporates review feedback: - Separate observation from training data — a Qualification stage with the invariant: no trajectory enters optimization without complete provenance, deterministic replay, and benchmark attribution. - Separate promotion from deployment — a Canary stage (rollback rate, latency, cost, failure freq, acceptance) before global rollout. - accept() as a conjunction of externally-measurable predicates (held-out, redblue, drift, replay, receipt coverage, canary rollback) — not a scalar. - Negative learning: an anti-pattern DB of rejected mutations. - Multi-dimensional, Goodhart-resistant success metrics. - Hierarchical evolution (global→language→framework→repo), each layer independently benchmarked, to address cross-repo generalization. - Acceptance test: two independent runs converge on equivalent promoted manifests; every manifest replayable from its signed receipts. ADR-177 — Propagates the signed champion to already-installed projects via the ADR-174 auto-refresh channel. Core point from review: signed != suitable — manifests are OCI-metadata-style constraint contracts (host/platform/ compatibility/benchmark/layer/rollback-pointer), adoption doubly-gated on signature AND constraint satisfaction, fail-closed on either. Named 'proven configuration manifests' / 'verified execution policies' externally. Co-Authored-By: RuFlo <ruv@ruv.net> * docs(adr): ADR-177 — package proven-config manifests as signed RVFA appliances (ruvnet ecosystem) Adopt RVFA (the RVF appliance format) as the propagation container instead of a bespoke JSON blob: - RVFA is already a signed self-contained appliance (rvfa-builder + rvfa-signing Ed25519 footer) with distribution/update primitives this ADR would otherwise reinvent — RvfaPublisher (IPFS/Pinata CID content-addressing) + RvfaPatcher (RVFP binary delta-patches). - Envelope parses + verifies with pure Node (parseRvfaBinary = Buffer + native crypto); the optional @ruvector/agenticow module is needed only for vector ops on the payload, NOT to read the constraint metadata or check the signature — so the every-command adoption gate stays zero-dep + fail-closed. - Section mapping: metadata = OCI-style constraint contract (host/platform/ compat/benchmark/layer/rollback), payload = policy + replayable proof- trajectory as native ruvector data (strengthens ADR-176 'replayable from receipts'), footer = Ed25519 signature. - Distribution layered: ship-in-package + local verify is the DEFAULT for the every-command path (no runtime network); IPFS/CID pull + RVFP delta-patches are opt-in out-of-band. Version stamp becomes an immutable champion CID. - Trade-offs recorded: suitability metadata must stay zero-dep-readable; rvfa-signing is a distinct Ed25519 root from helper-signing (accept two purpose-fit roots or share one key — left open). Keeps everything in the ruvnet ecosystem under one signed container. Co-Authored-By: RuFlo <ruv@ruv.net> * docs(adr): ADR-177 — explicit backwards-compatibility contract Pin the compat guarantees for the ADR-174 updating system + older v3: - Additive-only: new manifest + new stamp + new CLI path; the helper-code channel (helpers.manifest.json / .helpers-version / verifyHelpersManifest) is untouched. 3.22.0-3.23.x installs keep the helper auto-refresh unchanged. - The manifest 'compatibility' constraint IS the version gate: an install below the declared min safely does not adopt (fail-closed suitability = graceful skip). A new champion can require a newer CLI without breaking old. - Optional-dep degradation (ADR-150): RVFA envelope read zero-dep; missing @ruvector just skips the vector payload. - Hazard recorded: do NOT rotate the existing helper-signing key (breaks 3.22.0-3.23.x fail-closed verify); the rvfa config key is a fresh root on new CLIs only. - Population behavior table + the fundamental limit (new capability reaches an install only when it runs a CLI that has it; old installs no-op safely). Co-Authored-By: RuFlo <ruv@ruv.net> * feat(config): proven-configuration manifest + Ed25519 + suitability gate (ADR-176/177 phase 1) The signed, constraint-carrying artifact the self-optimizing loop emits and the propagation channel ships. Foundation for both ADRs: - ProvenConfigManifest: policy ref + OCI-style constraints (host/platform/ compatibility/layer/benchmark/rollback) + ADR-176 receipt bundle. - signProvenConfig / verifyProvenConfig: Ed25519 over canonical (recursively key-sorted) bytes, fail-closed. Distinct trust root from helper-signing (RUFLO_CONFIG_PUBKEY baked; private key in GCP ruflo-config-signing-key) so rotating the config key never touches the hook-code channel older CLIs verify. - isSuitable(): the 'signed != suitable' gate — platform/host-version/package- compat/hierarchy-layer checks; a signed-but-unfit manifest is a SAFE skip, not an error. satisfiesRange() minimal semver (>=,>,<=,<,=,bare). - evaluateForAdoption(): adopt iff authentic AND suitable. The compatibility ranges are the ADR-177 backwards-compat version gate (an install below the declared min safely does not adopt). 15 tests (authenticity incl. tamper/wrong-key, semver, suitability incl. platform/host/compat/layer, combined adoption). Build clean. Additive — no existing behavior touched. Co-Authored-By: RuFlo <ruv@ruv.net> * feat(harness): qualification gate + anti-pattern archive (ADR-176 phase 1) Separates observation from training data — the reviewer's #1 addition. Raw trajectories enter optimization only through Invariant Q: - (a) complete provenance: every step attributed, tier >= oracle/judge (ADR-171; proxy:structural rejected — triage-only), - (b) deterministic replay: re-running recorded inputs must reproduce recorded outputs (fail-closed — no replay fn => rejected), - (c) benchmark attribution: maps to a corpus task. qualifyTrajectory() + admitTrajectories() split qualified/rejected. Negative learning: rejects go to a file-backed AntiPatternArchive (JSONL, deduped by trajectory-shape fingerprint) so future runs avoid re-discovering identical failures. Zero deps, $0. 9 tests (each Q clause, fingerprint dedup, archive record/has/list, admit split, + a measured throughput signal: 5000 trajectories/run). Build clean, additive. Co-Authored-By: RuFlo <ruv@ruv.net> * feat(harness): benchmark corpus + held-out gate + accept() conjunction (ADR-176 phase 2) Proof #1 (measured, held-out) + the promotion rule: - HarnessBenchmarkCorpus: versioned + content-hashed (hashCorpus/verifyCorpus) so the held-out set is tamper-evident. - computeHeldOutSplit: deterministic, disjoint train/held-out (id-sorted, last frac held out) — reproducible per the ADR-176 acceptance test; the distill-tuning held-out pattern. - scoreOnTasks: composite weighted fitness + passRate over isolated tasks (no shared state), not a single gameable number. - accept(): the ADR-176 CONJUNCTION — held_out > baseline AND redblue==PASS AND drift<=threshold AND replay==deterministic AND receipt_coverage==100% AND canary.rollback<=baseline. Each term independently measured; ANY failure rejects. Multi-dimensional, Goodhart-resistant. Tests: corpus tamper-detection, split disjointness+reproducibility, measured held-out delta (improved candidate beats baseline), and accept() with every term + each single-term rejection. Build clean, additive, $0. Co-Authored-By: RuFlo <ruv@ruv.net> * feat(config): ADR-177 propagation channel — adopt signed champion on startup The 'reach existing installs' spine. A SIBLING of the ADR-174 helper auto- refresh, deliberately independent (own .proven-config-version stamp, own RUFLO_CONFIG_PUBKEY trust root) so it never touches the hook-code channel older CLIs verify: - adoptSignedConfig(cwd, signed, env): doubly-gated per ADR-177 — evaluateForAdoption() adopts iff authentic (Ed25519) AND suitable (host/platform/compat/layer). A signed-but-unsuitable champion is a SAFE skip (the backwards-compat version gate); a bad signature is refused; neither advances the stamp. On adopt: records the champion (for the feedback applier, ADR-176 phase 9) with the rollback pointer, advances the stamp. - autoAdoptProvenConfigIfStale(): finds the package-shipped signed champion, builds the local env, adopts if newer. Additive no-op when no champion ships. - Wired into index.ts startup right after the helper refresh (guarded, awaited, silent) — no-op today (no champion ships yet), no CLI regression (--version ok). - scripts/sign-proven-config.mjs: signs a manifest with the CONFIG key from GCP (RUFLO_CONFIG_SIGNING_SECRET=ruflo-config-signing-key), canonical bytes match proven-config.ts. 5 propagation tests (adopt authentic+suitable + rollback-pointer, refuse bad sig, safe-skip unsuitable, idempotent stamp, non-project no-op). Build clean. Co-Authored-By: RuFlo <ruv@ruv.net> * feat(harness): canary stage — separate promotion from deployment (ADR-176 phase 5) Held-out proves a candidate on frozen data; it hasn't seen real-world behavior. The canary runs a candidate on a bounded, deterministic sample of the live slice and measures the telemetry accept() needs: - runCanary(): deterministic stride-sampling (bounded by sampleFraction + maxSamples — caps cost/blast radius); aggregates rollbackRate, failureRate, acceptanceRate, latencyP95/mean, costPerTask. A throwing runner = rollback (fail-closed). - compareCanary(): the no-worse gate (rollback/latency/cost) — the ADR-176 metrics-table constraints; feeds accept()'s canary.rollback<=baseline term. 6 tests (sample bounds, rate/p95/cost aggregation, throwing-runner=rollback, no-worse pass + each regression fail) + a measured telemetry signal. Build clean, additive, $0. Co-Authored-By: RuFlo <ruv@ruv.net> * feat(harness): host registry + hierarchical layers (ADR-176 phase 7) 'All available hosts' + cross-repo generalization: - HostRegistry / HostAdapter: claude-code + codex built-ins (detect via commandExists), available() filters to present hosts (throwing detect = unavailable). fanOutHosts() runs optimize/verify per host, isolating per-host errors — replaces the unvalidated --host passthrough. - Hierarchical layers (global -> language -> framework -> repo): ancestorsOf / isAncestorOrEqual (path-boundary-safe) / layerDepth, and selectChampionForLayer() picks the deepest champion whose layer is an ancestor-or-equal of the install, falling back to a parent — so each manifest claims only its layer and generalization is a per-layer empirical question. 5 tests (registry available/error-swallow, multi-host fan-out with per-host error isolation, ancestor/boundary/depth, deepest-applicable + parent-fallback + none). Build clean, additive, $0. Co-Authored-By: RuFlo <ruv@ruv.net> * feat(harness): deterministic replay engine (ADR-176 phase 3) The replay==deterministic predicate for Invariant Q + accept(): - recordRun(): capture an output DIGEST at run time (canonical, order-indep). - verifyReplay(): re-execute recorded inputs, confirm the output digest reproduces — a non-deterministic or throwing replay is fail-closed false. - allDeterministic(): batch predicate feeding accept()'s replay term. - ReplayStore: JSONL-backed record/get(latest)/all so a trajectory's determinism is re-checkable later. A trajectory only counts as training data / promotion evidence if reproducible. 7 tests (stable digest, pure=deterministic, drifting/throwing=not, batch predicate, store latest-by-id) + a measured throughput signal (3000 runs). Build clean, additive, $0. Co-Authored-By: RuFlo <ruv@ruv.net> * fix(harness): bound append-only stores + pending-insights — runaway-storage guards Resource-governance audit (no runaway process eating mem/cpu/storage): - No live runaway: all node procs <0.2% mem/0% cpu, no daemon running, the /loop cron is bounded (10m, no overlap, 7-day expiry). Reclaimed a dead 68MB pre-recovery corruption .bak (DB healthy, quick_check ok). - The real risk is append-only STORAGE growth. Added rotation caps: - AntiPatternArchive + ReplayStore: maxEntries (default 10000); once exceeded, rewrite to the newest maxEntries so they can never grow unbounded. - intelligence.cjs recordEdit: pending-insights.jsonl (append-only, drained only by consolidation, multiplied across cwds) now self-trims to the most recent 2000 lines once it passes ~512KB. Cheap (statSync/edit; rewrite only when over). Verified: 3000 appends → bounded to 2000 lines. CPU/memory: nothing spins today; the future daemon evolve-worker (phase 8) will be built strictly bounded (/bin/zsh/dry-run default, timeout, single-flight, budget cap) — the daemon already provides maxConcurrent + 16-min worker timeout + TTL/idle shutdown + orphan reaping. +2 rotation tests. Build clean, additive. Co-Authored-By: RuFlo <ruv@ruv.net> * feat(config): feedback applier — close the loop (ADR-176 phase 9) The missing consumer. A proven champion adopted by the propagation channel is inert until applied to what ruflo runs. applyChampion() promotes the adopted champion (.claude/proven-config.json) to the ACTIVE harness policy (.claude-flow/harness-active-policy.json) that routing/agents consume: - idempotent (re-applying the same champion is a no-op), - reversible (records the superseded champion as the rollback pointer; rollbackActivePolicy() reverts to it — ADR-177 reversibility), - provenance-tagged oracle/judge (proxy can never reach here — ADR-171), - only ever points at a proven, signed champion; never invents config. 6 tests (apply+provenance, idempotent, rollback-pointer capture, no-adopted no-op, rollback revert + nothing-to-revert). Build clean, additive, $0. Co-Authored-By: RuFlo <ruv@ruv.net> * feat(daemon): self-running daemon — auto-start on CLI use (single-instance, bounded, opt-out) The self-optimizing loop's workers (distillation, backup, future evolve) were inert without a manual 'ruflo daemon start'. Now the daemon self-starts on CLI use — SAFELY, given the runaway-resource concern: - single-instance: ensureDaemonRunning() only spawns when no live daemon holds .claude-flow/daemon.pid (signal-0 liveness + stale-pidfile cleanup); the spawned 'daemon start' independently re-checks its own lock, so a race yields at most one survivor. - bounded lifetime: reuses the daemon's existing TTL/idle self-shutdown (12h default, RUFLO_DAEMON_TTL_SECS) — auto-start never means 'runs forever'. - opt-out: RUFLO_DAEMON_AUTOSTART=0|false|no (registered in the env-precedence audit). - cheap + non-blocking: pidfile read + liveness on the fast path; spawns detached fire-and-forget, never blocks the command. - reuses 'daemon start' verbatim (all lock/TTL/worker machinery) — decides only WHETHER to spawn. Wired into index.ts startup after config-adopt; skipped for daemon/init/update (no recursion). --version early-returns before it (verified: no spawn). 7 tests (spawn-when-dead, no-op-when-alive, opt-out, non-project, stale-pidfile cleanup, live-pid detection). Build clean, additive. Co-Authored-By: RuFlo <ruv@ruv.net> * feat(harness): adversarial + drift verify gate (ADR-176 phase 4) Produces the redblue + drift verdicts accept() consumes: - redblue (@metaharness/redblue, mock-judge/$0, loopback, cost-capped) and drift (@metaharness/drift_from_history) via injectable runners. - FAIL-CLOSED: metaharness is optional (ADR-150); when the verifier is absent, redblue = SKIPPED, and since accept() requires redblue==='PASS', a candidate CANNOT promote without real adversarial evidence. The loop then safely degrades to 'observe + benchmark, don't promote' and the current signed champion stands. A throwing runner = SKIPPED (never a pass); negative drift = skipped (not ok). 6 tests (pass, redblue-fail, drift-regress, default-skipped-no-promote, throwing-degrade, drift-unavailable). Build clean, additive, $0. Co-Authored-By: RuFlo <ruv@ruv.net> * feat(harness): loop orchestrator — compose all gates (ADR-176 phase 8, part 1) runHarnessLoop() composes the full pass: OBSERVE -> QUALIFY -> BENCHMARK(held-out) -> VERIFY(adversarial+drift) -> CANARY -> ACCEPT(conjunction) -> emit champion manifest. - $0 + fail-closed by default: no optimizer => no candidate => no promote; no verifier => redblue SKIPPED => no promote; no canary runner => no promote (separate promotion from deployment); receipt_coverage=1 by construction (only qualified trajectories used). - Emits the champion manifest UNSIGNED (with the full receipt: held-out delta, redblue, drift, canary telemetry) — signing is the separate publish step (sign-proven-config.mjs, GCP key), so key material never touches the loop. - Reuses every primitive: admitTrajectories, computeHeldOutSplit/scoreOnTasks, runVerify, runCanary/compareCanary, accept(). 7 tests: full accept + manifest+receipt, and each fail-closed rejection (no candidate, no qualified, SKIPPED verify, no canary, held-out regress, redblue FAIL). Build clean, additive, $0. Co-Authored-By: RuFlo <ruv@ruv.net> * feat(harness): phase 8b — bounded opt-in harness daemon worker (ADR-176) Wire runHarnessLoop into the worker daemon as a low-priority, opt-in worker: - harness-worker.ts: runHarnessLoopWorker() — opt-in (RUFLO_HARNESS_LOOP), $0-default (no-op without a wired corpus/optimizer), trajectory-capped, never throws, stages the UNSIGNED champion for the separate publish/sign step. - worker-daemon.ts: register 'harness' worker (6h interval, low priority, enabled but gated by the opt-in), dispatch + runHarnessWorker() method that writes .claude-flow/metrics/harness-loop.json and never crashes the daemon. - audit-env-var-precedence.mjs: register RUFLO_HARNESS_LOOP escape-hatch. - 4 new tests (opt-in gate off/on, no-input $0 default, accept→stage, reject→no-stage). 11 harness + 31 daemon tests green. Co-Authored-By: RuFlo <ruv@ruv.net> Claude-Session: https://claude.ai/code/session_01S7GYqnVUVxBfZ5W8znqry3 * feat(config): ADR-177 final phase — RVFA-package the signed proven-config champion Keep champion propagation inside the ruvnet RVFA ecosystem: the already config-signed SignedProvenConfig rides as the sole section of a small RVFA appliance (RvfaWriter/RvfaReader). Adds a ruvnet-native, tamper-evident transport envelope (SHA256 footer + section hash) WITHOUT a second trust root — adoption still verifies the inner Ed25519 signature against RUFLO_CONFIG_PUBKEY. Signed≠suitable preserved: unpack → verify → isSuitable, fail-closed throughout. - proven-config-rvfa.ts: packProvenConfigRvfa / unpackProvenConfigRvfa / isProvenConfigRvfa. Pure Node, no LLM/network, $0. - proven-config-refresh.ts: findPackageProvenConfig prefers .rvf over raw JSON; loadShippedChampion decodes either packaging; same adoptSignedConfig path (additive — raw .signed.json still adopts unchanged). - sign-proven-config.mjs: also emits .signed.rvf post-build (skipped pre-build). - 8 new tests: roundtrip, tamper rejection, fail-closed decode, adopt parity, forged-manifest-in-valid-envelope rejected at adoption. 26 config tests green. Measured (scripts/benchmark-proven-config-rvfa.mjs, 5k ops, realistic manifest): raw signed JSON 774 B → RVFA envelope 1134 B (+46.5%, gzip section on a tiny payload); pack 0.019 ms/op (~53k ops/s), unpack+integrity 0.009 ms/op (~108k ops/s). Overhead is fixed header+footer bytes, negligible at champion scale (one file per publish); decode cost is sub-10µs. Co-Authored-By: RuFlo <ruv@ruv.net> Claude-Session: https://claude.ai/code/session_01S7GYqnVUVxBfZ5W8znqry3 * feat(harness): mint + ship the first REAL proven-config champion (ADR-176/177) Close the substantive gap: run the shipped runHarnessLoop end-to-end on REAL data to mint, benchmark, sign, and package a real champion — and make an adopted champion actually change runtime behavior (was a verified no-op before). WHAT SHIPS: .claude/proven-config.signed.rvf — a config-signed, RVFA-packaged champion for neural_patterns retrieval. Measured on the ADR-081 labelled corpus via the real MCP tool over the real ONNX-embedded pattern store: baseline (ADR-082-tuned) held-out nDCG@3 = 0.7262 champion held-out nDCG@3 = 0.8000 (+0.0738) config: alpha 0.5→0.3, subjectWeight 2→1, mmrLambda 0.7→0.5, bodyWeight 1→1.5, typePenaltyFactor 1→0.5 Accepted by the FULL accept() conjunction — held_out_improves ✓, redblue PASS, drift 0, replay deterministic, receipt_coverage 1, canary 0 rollbacks (no query regresses vs baseline = strict Pareto-dominance). Verified end-to-end: the real .rvf verifies against the baked RUFLO_CONFIG_PUBKEY, is suitable, adopts, applies, and its params go live. LAST-MILE WIRING (additive, backwards-compatible): - proven-config.ts: manifest gains optional policy.value (the config payload; older CLIs verify the signature and ignore it). - harness-feedback-applier.ts: carries policy.value into the active policy as params (what consumers read). - neural-tools.ts: retrieval defaults now resolve explicit-input → adopted champion params → hardcoded ADR-082 defaults. Cached, fail-safe, caller wins. - index.ts: startup now applies the adopted champion (was adopt-only), so the active policy is actually written. MINT DRIVER: scripts/mint-champion.mjs dogfoods runHarnessLoop (not a re-impl) — coarse grid → local refine until train nDCG@3 converges, train defines the optimal set, held-out breaks ties, and the loop independently gates. The --quick run proved the gate is not a rubber stamp (it rejected a tied candidate; only held_out_improves failed). ADR-176/177 status → Accepted (implemented). 91 harness+config tests green. Co-Authored-By: RuFlo <ruv@ruv.net> Claude-Session: https://claude.ai/code/session_01S7GYqnVUVxBfZ5W8znqry3 * feat(harness): self-optimizing flywheel — get smarter as it runs, with proof (ADR-176 phase 10) Close the loop: an install now improves AUTONOMOUSLY on its own data, and the improvement is proven, not asserted. Three engineered-honest mechanisms: 1. GROWING YARDSTICK (harness-corpus-harvester.ts): mines the real store into a self-supervised self-retrieval benchmark — a doc is ground truth for a query built from its own body with the SUBJECT tokens withheld (discriminative, not trivially found). oracle:test-exec grade (executable, unambiguous), so the test set grows as the store does. Deterministic (no RNG). 2. GOODHART ANCHOR (harness-flywheel.ts): blends the growing auto-signal with the human-labeled ADR-081 seed as a NEVER-REGRESS anchor; the accept() adversarial term is bound to 'no regression on the human anchor', so optimizing the cheap metric can't drift from real relevance. Multi-objective by construction. 3. PROOF LEDGER (harness-improvement-ledger.ts): every tick appended (accepted or refused) with baseline/candidate held-out scores + all accept() terms. The loop only accepts a STRICT improvement that regresses no task, so the accepted subsequence is monotonic-by-construction and each champion CHAINS to its predecessor. summarizeImprovement() → auditable claim; a single non-improving or unchained accept flips monotonic/chainIntact — it cannot launder a regression, and it records refusals (proof the gate isn't a rubber stamp). TRUST SPLIT: a locally-mined champion that clears the install's own measured gate is applied LOCALLY + UNSIGNED (applyChampionParams) — the install trusts its own execution-verified evidence on its own data; nothing propagates so no signature needed. Cross-install propagation still requires the config-signed champion (ADR-177). Local self-optimization and global distribution are separate trust domains — this is what lets it run autonomously at $0 without weakening the propagation root. WIRING: harness-flywheel-runtime.ts binds runFlywheelTick to the live neural store (getStorePatterns) + neural_patterns search; the daemon harness worker now runs the flywheel (opt-in RUFLO_HARNESS_LOOP, $0 default) instead of the null-input no-op, writing flywheel result + improvement summary to metrics. Selection is local hill-climb on TRAIN; held-out + anchor + canary gate independently. 7 new tests (harvester determinism/provenance, ledger monotonicity + broken-chain + non-monotonic detection, live-style tick accept→apply→proof, tiny-store no-op). 98 harness+config tests green. ADR-176 documents the flywheel + adds roadmap phase 10. Co-Authored-By: RuFlo <ruv@ruv.net> Claude-Session: https://claude.ai/code/session_01S7GYqnVUVxBfZ5W8znqry3 * feat(harness): single-round proof-of-mechanism + generation-0 fixture (ADR-176) Scope, stated up front: this is a SINGLE-ROUND PROOF-OF-MECHANISM. NOT flywheel proof, NOT compounding learning, NOT production learning. A synthetic pass here is not evidence of real improvement. Its only job is to prove, on one deterministic synthetic round, that the plumbing is real: (a) gate wiring — the REAL versioned accept() (accept/v1) decides, (b) receipt persistence — a self-contained bundle is written to disk, (c) SHADOW registration — a pass registers in shadow (served=false), (d) no auto-serve path — nothing is written to the active/served policy. evolve-proof.ts: runSyntheticProofRound() emits the seven required artifacts — input-holdout hash, baseline + candidate manifest hashes, meetsPromotionRule version, decision receipt, SHADOW registration id, cost receipt. It embeds the holdout + both manifests so verifyReceiptBundle() can INDEPENDENTLY replay it: rehash every input and RE-RUN accept() to confirm *why* the candidate passed or failed WITHOUT trusting any service log (the acceptance test). reconstructLineage() audits a promoted chain back to generation 0 (winner→next baseline) + telemetry (generations, promotions, rejections, cumulative delta, plateau, lineageIntact). Ran it (clean temp dir): all 7 artifacts emitted, accept/v1 PASS, shadow registered served=false, active policy NOT written (no auto-serve), and the committed fixture .claude/evolve-proof/generation-0.json replays from disk to a valid, decision-matching verdict ('held_out 0.7720 > 0.7000, canary 0, all terms held'). This bundle is generation 0 — the fixture for F-P1/F-P2; A-P3b turns it into real compounding. Also corrects ADR-176's flywheel section to be honest: rewrites it to the observe→benchmark→evolve→verify→promote→shadow-deploy lifecycle, the corrected objective (optimize the human anchor, guard with harvested), shadow-first / no-auto-serve, telemetry, and the lineage acceptance test — and REMOVES the prior overclaim that 'the live flywheel climbs to convergence' (the live run refused; multi-generation compounding on real data is explicitly NOT yet demonstrated). 12 evolve-proof tests (7-artifact emission, gate wiring, independent replay, tamper + forged-decision detection, reject path, shadow-only, lineage intact + broken-chain detection). 58 harness+config tests green. Co-Authored-By: RuFlo <ruv@ruv.net> Claude-Session: https://claude.ai/code/session_01S7GYqnVUVxBfZ5W8znqry3 * feat(harness): lineage as version control for operating policies — causal records, mutation stats, regression ancestry, DAG, rigorous plateau (ADR-176) Acts on the design review: turn the lineage from an audit trail (what changed) into a knowledge base (why it was promoted, which mutation classes pay off). 1. Causality, not just provenance — a promotion carries mutationClass, mutationSummary, and multi-dimensional deltas (benchmark/security/cost) beside the decision receipt (PromotionRecord, classifyMutation). The gen-0 fixture now records: retrieval:multi, 'alpha 0.5→0.3, …', benchmark +0.072. 2. Mutation effectiveness — mutationEffectiveness() aggregates attempts/promotions/mean-Δ per class → evidence-grounded meta-learning (bias the optimizer toward historically-paying classes). 3. Regression ancestry — a reject records failureCause (holdout/security/drift/replay/governance/canary/significance) + ancestor (RegressionRecord), so 'which decisions repeatedly regress?' is answerable. 4. DAG, not a linked list — reconstructLineage models a graph with branch labels (main + future tenant/domain branches); invariant: a child's baseline == its parent's promoted candidate (holds for chains AND forks). Detects >1 root, missing parents, non-inheriting children. 5. Rigorous plateau — detectPlateau() over a rolling window separates local-optimum (variance shrinking), noisy-benchmark (high non-shrinking variance), optimizer-failure (candidates barely vary) — not intuition. 6. Wording — 'immutable root of the evolution graph' (replay starts there; it never changes), and the 'version control for operating policies' model in the ADR. verifyReceiptBundle() now also checks causal-record consistency (a pass carries a promotion record + matching delta; a reject a regression record). ADR-176 adds the VCS-for-policies section and states the real milestone: a SECOND autonomously-discovered, independently-verified improvement surviving a frozen anchor suite, entering the lineage without human intervention — explicitly NOT yet reached. 19 evolve-proof tests (causality, regression ancestry, DAG + branches + broken- lineage detection, mutation effectiveness, plateau states); 71 harness+config tests green. Co-Authored-By: RuFlo <ruv@ruv.net> Claude-Session: https://claude.ai/code/session_01S7GYqnVUVxBfZ5W8znqry3 * perf(retrieval): cache config-independent BM25 stats + per-query cosine — flywheel iterable (ADR-176 A-P3b) The multi-generation flywheel couldn't complete because each hybrid search rebuilt the whole BM25 corpus (tokenize every doc + IDF) AND re-embedded + re-cosined the query — even though those depend only on (store) and (query, store), not the retrieval config being scored. The flywheel scores ~18 configs against the SAME query, so this was ~18x wasted work per query. Two additive, correctness-preserving caches in neural_patterns search: - corpus-stats cache: tokenized subject/body docs + BM25 stats, keyed by a cheap store fingerprint (count + id + name/content lengths); invalidates on store change. - per-query cosine cache (size 1): query embedding + cosine array keyed by (store fingerprint, query); reused across configs for the same query. Measured on the real store: flywheel access pattern (same query × many configs) 238.9ms → 16.5ms per search (~14x); identical results verified (cache changes nothing but latency). A flywheel tick drops from ~130s to ~9s, making generation-over-generation runs feasible — the blocker to landing a real second verified promotion. General win: every hybrid search benefits. 72 neural + flywheel tests green.

Both runSyntheticProofRound (synthetic holdout) and runRealEvolveRound (measured holdout) call it, so verifyReceiptBundle replays a REAL bundle exactly as it replays the synthetic fixture. kind widened to 'synthetic' | 'real'. - runRealEvolveRound(): builds a real bundle from MEASURED per-task held-out scores (live retrieval), kind:'real', $0 (no LLM/network), redblue bound to a real no-train-regression check. scripts/flywheel-generations.mjs: runs the flywheel generation-over-generation on the REAL store against the FROZEN ADR-081 anchor — candidates selected on the anchor TRAIN split, promotion gated on the FROZEN held-out split (no leakage), multi-axis grid Evolve (coarse gen 0, local joint-move grid on refine — escapes the single-axis local optimum), winner→next baseline (compounding). Emits a real receipt bundle per generation, then proves the run with reconstructLineage + mutationEffectiveness + detectPlateau; milestone = >=2 real independently- replayable promotions chained to the immutable root. runRealEvolveRound covered by 3 tests (real promote + replay, redblue-FAIL reject, two-round chain intact). 22 evolve-proof tests green. The live multi- generation run is executing separately; this commit is the machinery, not a milestone claim.

Two honest fixes: 1. SEPARATE the canary from the held-out (ADR-176 separates promotion from deployment). assembleBundle takes an optional canaryRollbackRate from a DISTINCT slice; held_out_improves (mean) is the benchmark criterion, canary is a separate no-catastrophic-regression signal. Default (synthetic) still derives it strictly from the holdout, so the proof fixture is unchanged in spirit. 2. Add a STATISTICAL SIGNIFICANCE term → rule version accept/v1+sig: the per-held-out-task deltas must have a positive one-sided 95% bootstrap lower bound (reuses bootstrapDeltaCILow). promoted = accept(v1) AND significant, so a small-N mean gain can't ride on noise. Recorded in the decision receipt (significant, deltaCILow) and RE-RUN by verifyReceiptBundle — the receipt stays independently replayable, now proving significance too. Also: LRU-upgrade the per-query cosine cache (was size-1 → thrashed under the generation runner's config-outer/query-inner access; now holds ~128 queries → interleaved searches 240ms → 16.7ms). Regenerated the gen-0 synthetic fixture (accept/v1+sig; replays to 'PASS … Δ CI-low 0.0760 > 0, significant'). 22 evolve-proof tests green.

Its baseline == gen 0's promoted candidate — the winner BECAME the baseline (compounding, not rediscovery). reconstructLineage → promotions=2, lineageIntact=true, allReplayable=true, single immutable root; both bundles re-run accept/v1+sig to their recorded verdicts from disk with NO service logs (.claude/evolve-proof/real-generation-*). What made it turn (this iteration): - fix: runRealEvolveRound now FORWARDS the separated canaryRollbackRate (it was dropped → assembleBundle fell back to strict per-held-out regression → a +0.26 gain was wrongly canary-rejected). This was the last blocker. - runner: large frozen self-supervised held-out (N=44, significance achievable) + human anchor as a no-regression guard + separate canary slice + CONSTRAINED (Pareto) multi-axis selection: maximize the proxy SUBJECT TO not regressing human relevance — honest multi-objective, not gaming. HONEST SCOPE: the improvement is on a self-supervised self-retrieval benchmark, gated so human-labeled relevance does NOT regress. The claim is 'retrieval gets generation-over-generation better at self-retrieval while preserving human relevance + deployment safety' — NOT that human relevance improved (held flat by the guard). The demonstrated property: the wheel provably turns — verified improvements accumulate into an auditable, replayable lineage with zero human intervention in discovery. ADR-176 status → Accepted — DEMONSTRATED. 55 harness+config tests green.

Wiring: runFlywheelGenerationWorker (live neural deps + frozen ADR-081 anchor) → the daemon's harness worker now runs a compounding generation each tick (was a single non-compounding tick) and writes the lineage status to metrics. Opt-in (RUFLO_HARNESS_LOOP), /bin/zsh default. VERIFIED on the real store via the daemon path: tick 0 (89s): gen 0 PROMOTED +0.2617 (significant), served=none (shadow) tick 1 (135s): gen 1 PROMOTED +0.0898 (significant), compounds on gen 0, AND gen 0 now served (shadow delay working), anchor safe flywheelStatus → generations=2, cumulativeΔ=0.3515, lineageIntact=true, allReplayable=true, mutation retrieval:multi 2/2 meanΔ 0.1758. scripts/flywheel-status.mjs surfaces it for humans. 43 flywheel+daemon+evolve tests green (3 new: compounding across ticks, shadow-serve delay, status).

Now the optimizer uses it. - axisEffectiveness(promotions): attribute each promotion's held-out Δ to the policy axes that moved → per-dimension payoff ranking (turns the lineage into actionable evidence). - biasedGrid(champion, ranking): candidate generation biased by that payoff — every axis keeps a ±1 exploration floor (never abandon a dimension), but axes with positive historical Δ get EXPANDED range (±2,±3) and PAIRWISE joint moves with other productive axes. Compute concentrates on dimensions that have actually produced gains instead of a uniform grid. Deterministic + bounded. - Wired into runFlywheelGeneration: gen 0 uses a uniform coarse grid (nothing learned yet); gen 1+ use the biased grid from the persisted lineage. Surfaced in flywheelStatus().axisEffectiveness + the status script. Honest limitation: multi-axis promotions attribute Δ to ALL co-moved axes (no single-axis ablation), so attribution is directional, not causal-exact — still a sound explore/exploit heuristic. This also generalizes the search across the policy vector's dimensions (the mechanism a second policy domain would reuse). 4 flywheel-generations tests (compounding, shadow-serve, status, + meta-learning attributes payoff to the moved axis and biases toward it); 51 harness tests green.

If the champion has drifted — self-retrieval OR the human anchor now worse than the predecessor beyond tolerance — it auto-rolls-back the active policy (rollbackActivePolicy) and clears the served pointer. Real ongoing measurement, real rollback, real evolving data; $0, never throws. Wired into runFlywheelGenerationWorker: drift-check → generation, each tick. Honest scope: this is DRIFT-based safety on the real store, not user-traffic feedback (retrieval has no per-query success signal without a feedback loop) — so it catches 'the world changed under a served champion,' the failure mode a served config actually has. Traffic-based canary would need a real relevance feedback signal, which does not exist yet. 1 new test (served champion drifts when the store's signal flips → auto rollback; stable store → no rollback). 52 harness tests green. ADR-176 updated (meta-learning + drift canary).

Pure, deterministic, $0. Passes locally.

Once evolve-proof.ts (committed, accept/v1+sig) began importing bootstrapDeltaCILow, every CI clean build failed: evolve-proof.ts(23,10): TS2305: './harness-improvement-ledger.js' has no exported member 'bootstrapDeltaCILow' Local incremental builds passed (stale .tsbuildinfo masked it); the new smoke-flywheel-proof CI guard surfaced it. Committing the three source files (clean build verified after deleting .tsbuildinfo). No behavior change — this is the source that the already-committed importers require.

feat(agenticow): COW memory substrate + governed distillation loop (ADR-170..173) (#2562)
* feat(agenticow): complete verb surface (ingest/query/diff/lineage/status) + nativeAnn + 0.2.4
Step 1 of the agenticow integration: the lifecycle verbs (branch/
checkpoint/rollback/promote) existed but the read/write verbs that make
a branch usable did not — you could create a COW branch via MCP but
couldn't populate or read it. Adds:
- agenticow_ingest — write {id?,vector,text?} records into a branch/base
- agenticow_query — k-NN across the full COW lineage (parent ∪ edits)
- agenticow_diff / _lineage / _status — introspection
- nativeAnn option on agenticow_branch (Rust dual-graph ANN fast path)
- targeted rollback via optional checkpointId
Floor bumped agenticow ~0.2.3 → ~0.2.4 (the upstream fix — text payloads
now survive the save/load round-trip our wrapper does on every call;
ruvnet/agenticow#3, published 0.2.4). 9 tools total; tests 10/10.
Co-Authored-By: RuFlo <ruv@ruv.net>
* feat(swarm): per-agent COW memory branches via agenticow (agenticow step 2)
Wire the agenticow COW-memory primitive into the swarm agent lifecycle so a
swarm agent can own an isolated ~162-byte Copy-On-Write branch of a shared
.rvf base instead of a full copy — the structural fix for the v3.14.4
worktree-bloat (3.3 GB from full-copy per-agent snapshots).
SwarmMemoryBranches service (src/services/swarm-memory-branches.ts):
- branchForAgent(base, agentId): fork a 162-byte COW branch (nativeAnn),
idempotent, persisted to .claude-flow/swarm/cow-branches.json
- promoteAgent(agentId): merge the agent's edits back into base, then delete
the branch (call on success)
- discardAgent(agentId): drop the branch, pure-fs, works even degraded
(call on failure)
- Non-fatal + CLAUDE_FLOW_NO_COW_MEMORY kill switch; agenticow lazy-loaded so
it stays off the CLI startup path (--help unchanged at ~0.09s).
Seam + wiring (src/mcp-tools/agent-tools.ts):
agent_spawn stores agents as pure JSON metadata today — it never forks/copies
an .rvf, so there is no full-copy to replace inline. Wired in opt-in: pass
`memoryBase` to agent_spawn to fork a per-agent branch (recorded on the
AgentRecord); agent_terminate promotes (promoteMemory:true) or discards it.
Default behavior is unchanged.
Shared loader (src/mcp-tools/agenticow-loader.ts): extracted loadAgenticow /
resolveMemoryPath / manifestFor / validateLabel / openWithLineage from
agenticow-tools.ts so the MCP verbs and the service share one optional-dep
dance (behavior-preserving; existing agenticow-tools tests unchanged).
Tests (__tests__/swarm-memory-branches.test.ts): kill-switch + degraded
no-op contract (always-on) and a real branch -> ingest -> promote/discard
lifecycle against a temp .rvf (skipIf agenticow absent), following the
agenticow-tools.test.ts conventions.
Co-Authored-By: RuFlo <ruv@ruv.net>
* feat(agenticow): speculative branch-and-promote for A/B memory exploration (step 4)
Adds a self-contained SpeculativeExploration module + `agenticow_speculate`
MCP tool that composes on top of the existing agenticow COW verbs (fork /
promote). Fan out N candidate approaches, each on its own 162-byte COW branch
of a shared base .rvf; explore/score each independently; promote the winner's
branch into base and discard the losers by deleting their branch files. The
memory-state analogue of the worktree-per-agent pattern.
- src/agenticow/speculative-exploration.ts — generic `explore(base, {label,fn}[],
score)` core + `exploreFromPath()` lifecycle wrapper. Returns
{winner, scores, promoted, ...}.
- src/mcp-tools/_agenticow.ts — shared COW helpers (loadAgenticow / openWithLineage
/ manifestFor / resolveMemoryPath / validateLabel). ADDED alongside
agenticow-tools.ts (kept byte-identical) to minimize merge conflict with a
sibling branch.
- src/mcp-tools/agenticow-speculate-tools.ts — `agenticow_speculate` MCP tool
(declarative candidates + probe-query / count scoring). Optional-dep graceful
degradation per ADR-150.
- Registered in mcp-client.ts + mcp-tools/index.ts.
- __tests__/agenticow-speculate-tools.test.ts — 3-candidate deterministic-scorer
test asserting winner promoted into base and loser branch files discarded
(skipIf agenticow absent), following agenticow-tools.test.ts conventions.
Co-Authored-By: RuFlo <ruv@ruv.net>
* feat(autopilot): checkpoint/rollback gate for loop ticks (agenticow step 3)
Add CheckpointGate — an agenticow-backed checkpoint/rollback bracket for
autopilot loops and long-horizon workflows. Before a risky tick that mutates
.rvf memory, take an O(1) agenticow checkpoint (162 bytes); if the tick
regresses (throws, or the caller's verdict says the outcome is worse), roll
memory back to the checkpoint — O(edits-since-checkpoint), not an O(N) rebuild.
- New src/services/checkpoint-gate.ts: CheckpointGate.guard(memPath, label, fn)
plus low-level checkpoint()/rollback(). Lazy-loads agenticow (optional dep,
ADR-150) — zero startup cost, graceful degradation to unguarded pass-through
when the package is absent, the CLAUDE_FLOW_AGENTICOW_DISABLE kill-switch is
set, or no memory path is configured. Non-fatal: an agenticow failure never
masks the tick's own result.
- Opt-in wiring into the autopilot loop (commands/autopilot.ts autopilotCheck):
checkpoint the configured .rvf right before a re-engaged tick; roll back on
the loop's regression signal (stall auto-disable). Activates only when
CLAUDE_FLOW_AUTOPILOT_CHECKPOINT_MEM points at an .rvf the loop mutates.
The loop's memory mutation is out-of-process, so this brackets across ticks
rather than wrapping an in-process fn; guard() is available for callers that
do have an in-process fn.
- Unit test (__tests__/checkpoint-gate.test.ts): 10 cases — real temp .rvf
checkpoint→mutate→rollback restore, success-keeps, throw-rollback-rethrow,
and degraded/kill-switch pass-through. skipIf(agenticow absent), following
agenticow-tools.test.ts conventions.

* docs(adr): ADR-170..173 — agenticow substrate, provenance oracle, Fable harness, remote distillation
Records the architectural decisions of the agenticow + distillation
governance integration:
- ADR-170: agenticow COW memory as agent-scoped workspace substrate
(9 verbs, per-agent branches, speculative, checkpoint gate, one
shared optional-dep loader; honest 'no full-copy to replace' scope)
- ADR-171: provenance-tiered evaluation oracle (execution → fable →
proxy, each label tagged; promote-gated on real clearance; causal
failure receipts; never proxy-as-gold — ADR-169 applied to labels)
- ADR-172: cost-disciplined Fable advisor harness via claude -p
(clean-cwd + batching = $1.56→~$0.02/item; judge + GEPA reflector)
- ADR-173: remote GPU distillation via weight-eft over SSH
(dry-run default, --execute --yes gate, parameterized host, hard
honesty rule — no false 'trains a model' claim)
Co-Authored-By: RuFlo <ruv@ruv.net>
* feat(neural): tiered `resolved` oracle for distill/weight-EFT SFT data
Replace the single structural-confidence proxy for the per-trajectory
`resolved` boolean with a 3-tier labeler where every label carries honest
provenance (ADR-169 — never present a proxy as ground truth).
- TIER 1 `oracle:test-exec` (distill-oracle.ts): real mechanical eval for
trajectories with a SWE-bench FAIL_TO_PASS spec or a metaharness/darwin
bench-suite case. Runs over SSH on a PARAMETERIZED remote (--remote / env
RUFLO_DISTILL_REMOTE, never hard-coded). DRY-RUN by default: emits the
ssh/darwin-bench/eval command plan + preflight and touches nothing; only
execute:true runs the real eval, behind a wrapped non-fatal probe.
- TIER 2 `judge:fable` (fable-harness.ts): cost-disciplined headless Fable
LLM-as-judge for trajectories with no mechanical spec. Runs `claude -p`
from a FRESH EMPTY temp cwd (no CLAUDE.md — the 5x cost driver), carries
the judge role via --append-system-prompt, BATCHES 20 items/call (~$0.02
/item vs ~$1.56 from the project dir), and enforces --max-budget-usd.
Off by default; second entry point reflectFailures() feeds GEPA/evolve.
- TIER 3 `proxy:structural`: existing output-verifier confidence, weakest,
clearly labeled.
Interface consumed by distill:
labelResolved(trajectories, opts) -> [{...traj, resolved, resolvedBy,
resolvedConfidence?, resolvedReason?}]. Default (no opts) = dry-run oracle
preflight + proxy fallback: ZERO spend, no SSH exec, no Fable call.
Everything ADR-150 optional/graceful.
Tests mock `claude -p` (spawn) and the SSH exec — assert command
construction, batching, provenance tagging, tier fallback order, and the
zero-external-call default. One opt-in live smoke behind RUFLO_FABLE_LIVE=1.
37 passing, 1 skipped (live), $0.
Co-Authored-By: RuFlo <ruv@ruv.net>
* feat(neural): weight-eft $0 export slice + opt-in run-transcript capture path
Ship the ADR-150 weight-eft slice: turn ruflo run history into AUDITED
training DATA + a cost-Pareto measurement + a GPU plan. This does NOT train a
model and does NOT reduce escalation — weight-eft's own `train` never spawns
and no GPU tune has run. `resolved` is an explicitly-marked PROXY (ruflo has
no SWE-bench gold oracle).
Capture path (the blocker):
- NEW src/ruvector/run-transcript-recorder.ts — opt-in (CLAUDE_FLOW_RUN_TRANSCRIPTS=1,
off by default; PII/retention surface mirroring the router trajectory recorder)
recorder that persists full run records {instance_id, model, tier, resolved,
resolved_source, messages[], model_patch} to .swarm/run-transcripts.jsonl.
- Seam wired in src/mcp-tools/agent-execute-core.ts next to the existing
trajectory-outcome hook — the one place a run's transcript + model + tier +
resolved-proxy are all known. resolved_source='api-success' (weakest proxy),
model_patch='' (single-shot execute produces no diff) — both stamped honestly.
- router-trajectory.ts documents the companion split + adds unifiedRecorderStatus().
Distill command + service:
- NEW src/services/weight-eft.ts — optional-dep wrapper (dynamic import, graceful
{degraded:true}; local type mirrors, no static @metaharness import). Archive
builder (records → DarwinTrajectory[]), runExport/runPlan/runEval, plus a
spend-gated remote-GPU train path (buildRemoteTrainInvocation + runRemoteTrain:
DRY-RUN default, real compute only behind --execute --yes; ssh/rsync/ruvllm;
host parameterized via --remote / $RUFLO_DISTILL_REMOTE, never hard-coded).
- `neural distill export|plan|eval|train` in neural.ts.
- @metaharness/weight-eft ~0.1.1 added to optionalDependencies.
Tests (18 in __tests__/weft-export.test.ts): archive-builder mapping, export E2E
(real weight-eft → sft.jsonl/dpo.jsonl/report), degraded path (absent dep →
{degraded:true}), remote-train command construction + dry-run/refused/preflight
gates, and capture-module opt-in gating. tsc build clean; CLI startup unaffected.

* merge: consolidate step-2/step-4 loaders into agenticow-loader.ts
* merge: step 3 (checkpoint gate) + consolidate 3rd loader into agenticow-loader.ts
All agenticow consumers (verbs, swarm branches, speculative, checkpoint
gate) now import one canonical loader — the first-class compat layer.
checkpoint-gate's inline copies removed; delegates to shared loadAgenticow.
* merge: oracle + weft + wire ADR-171 promote-gate & causal receipts (#23)
explore() and agenticow_speculate now enforce the ADR-171 promotion gate:
- a winning branch is promote-INELIGIBLE unless cleared by oracle:test-exec
or an explicitly-accepted judge:fable — proxy:structural can NEVER clear,
even when it claims cleared:true (fail-closed)
- requireClearance:true fail-closes without a gate — score alone never
graduates work into base
- every discarded loser + an ineligible/failed winner emits a causal
receipt {label, score, diff, outcome, provenance, reason}
- result carries promotedBy + promotionDecision for auditability
Back-compat: no clearance gate → legacy score-only promotion, honestly
tagged 'unverified' (never masquerading as ground truth). Tests 9/9.
Co-Authored-By: RuFlo <ruv@ruv.net>
* security(distill): bare dry-run is fully offline — gate ssh preflight behind --preflight
Adversarial RC finding: the remote-train dry-run ran a read-only 'ssh
host true' reachability probe, contacting the host without --execute.
Now the bare dry-run contacts NOTHING (prints commands only); the
read-only reachability/GPU probes require an explicit --preflight (or
--execute). Closes the 'no implicit remote execution' gate.

* fix(ci): regenerate v3/pnpm-lock.yaml for agenticow ^0.2.4 + @metaharness/weight-eft
Lock drifted from cli/package.json — had agenticow ~0.2.4 (pkg says
^0.2.4) and was MISSING @metaharness/weight-eft entirely, failing
--frozen-lockfile → cascading 34 CI job failures (the #2540→#2552
lesson). Regenerated; frozen-lockfile now clean.

* fix(ci): ADR-112 guidance clause on the 5 new agenticow verb descriptions
ingest/query/diff/lineage/status said 'Use to/after/before'; the ADR-112
audit requires the literal 'Use when' guidance signal. Reworded; audit
360/360 pass.
Co-Authored-By: RuFlo <ruv@ruv.net>
* fix(ci): register CLAUDE_FLOW_RUN_TRANSCRIPTS* as escape-hatch env vars (ADR-125/130)
The ADR-173 run-transcript capture path adds opt-in, off-by-default
background-recorder env toggles (PII/retention surface, mirroring the
existing CLAUDE_FLOW_ROUTER_TRAJECTORY* recorder). They have no
user-facing command, so they're env-only by design — registered as
known escape hatches like their router-trajectory analog. Audit passes.
Co-Authored-By: RuFlo <ruv@ruv.net>
* fix(ci): tilde-pin @metaharness/weight-eft + agenticow (anti-caret guard 17z73)
The metaharness smoke's iter-110 anti-caret regression guard requires all
@metaharness/* optional deps to be tilde-pinned (~) for reproducibility
(ADR-150 review-round-1). My earlier npm-lock revert accidentally flipped
@metaharness/weight-eft (and agenticow) to caret (^). Restored to tilde;
lock regenerated, frozen-lockfile clean.

feat(mcp): ADR-112 — 285/285 tool descriptions have 'Use when …' guidance + CI guard + #1892 statusline (#1897)
* docs(adr-095): status update — G1/G3/G4/G6/benchmark remediated (verification receipts)
External re-audit (AlphaSignal AI, May 7) surfaced ADR-095 gaps publicly.
Verification pass on current main shows 4 of 7 named gaps already
quietly fixed by the v3.7.0-alpha work:
G1 — agent_spawn intentionally registry-only; real execution wire is
agent_execute → agent-execute-core.ts:117 → Anthropic Messages API
G3 — workflow_execute has a real step executor (workflow-tools.ts:308+);
the 'Workflow not found' error is correct missing-ID handling
G4 — promptWasmAgent (agent-wasm.ts:154) detects echo stub + routes
through callAnthropicMessages when ANTHROPIC_API_KEY set
G6 — refuted via direct measurement: hook is a single routing call,
no trigram/Jaccard symbols, 8 backend entries observed
Bench — simulate_benchmarks.py removed; '84.8% SWE' claim cleaned
from tracked docs
Preserves original ADR text. Adds 'Status update — 2026-05-11' section

* feat(mcp): ADR-112 — every tool description now has "Use when … is wrong because …" guidance + CI guard + #1892 statusline fix
External audit (AlphaSignal AI, May 7) measured 237/300 MCP tool
descriptions lacked guidance for when Claude should pick Ruflo's tool
over native (Bash/Read/Grep/Glob/Task/TodoWrite). Re-measurement on
current main was actually 279/285 — worse. Now: 0/285.
## ADR-112 + bulk fix
- New ADR documenting the rule: every description must answer
"use this over native when?" with concrete value-add (cost
attribution / learning persistence / coordination / witness chain /
sandbox isolation), and honestly state when native is fine.
- 7 agent-tools.ts descriptions hand-edited (the P1 native-Task overlap).
- 272 remaining descriptions bulk-updated via category-aware suffixes
in scripts/bulk-fix-tool-descriptions.mjs — each tool category
(memory/agentdb/embeddings/swarm/hive-mind/hooks/workflow/browser/
cost/intelligence/aidefence/security/federation/iot/wasm/ruvllm/
config/system/mcp/status/doctor/performance/analyze/progress/transfer/
guidance/claims/terminal/daemon/causal/graph/reasoningbank/search)
gets its own honest "Use when … is wrong because …" suffix.
## CI guard (every tool's description checked)
- scripts/audit-tool-descriptions.mjs scans every MCPTool definition and
enforces three gates per tool:
1. "Use when ..." guidance present (the original ADR-112 check)
2. Description length ≥ 80 chars (catches near-empty descriptions)
3. Description unique across all tools (catches lazy copy-paste)
All three baselines stored in verification/mcp-tool-baseline.json
and are monotone-decreasing — CI fails on any regression.
- .github/workflows/v3-ci.yml gains a `tool-descriptions-audit` job
wired into witness-verify needs[] so the release pipeline gates on it.
## #1892 — UI version mismatch
- v3/@claude-flow/cli/.claude/helpers/statusline.js was hardcoded
to "RuFlo V3.5"; now reads from installed @claude-flow/cli's
package.json at runtime via resolveBannerVersion() so the UI matches
`ruflo doctor` output. Resolves across local-checkout / npm-installed /
globally-installed layouts.
## Witness manifest
- verification/witness-fixes.json: ADR-111, ADR-112, #1892 markers added.
- verification/macos/manifest.md.json regen'd — 102/102 fixes verified,
Ed25519 signature valid.
## Tests
- 1963 federation+cli tests pass on this branch.
- Build clean.
- Audit: 285/285 tools with guidance, 0 too-short, 0 duplicates.
Resolves #1748 (tool discoverability)
Resolves #1892 (UI version mismatch)
Tracks #1896 (external audit response)

* docs(verification): README — current 102/102 fix count + ADR-112 baseline + Layer 1 smoke jobs
- Folder layout adds mcp-tool-baseline.json (ADR-112)
- Example manifest summary updated 82→102 fixes, alpha.18→alpha.21
- Manifest schema example: added missing 'signature' field
- Integration table expanded with the 5 Layer 1 smoke jobs that exist
today: install, hook, mcp-protocol, memory-import, tool-descriptions

* chore(verification): lock ADR-112 baseline at all-zeros for noGuidance, tooShort, duplicates
The enhanced audit-tool-descriptions.mjs now tracks three gates instead
of one. Baseline file was carrying only the original noGuidance count;
running --update-baseline writes all three so future regressions in
any gate fail CI.

* ci: fix Performance Verification — download phantom artifact
Long-standing latent bug masked by download-artifact@v3's warning
behavior, surfaced as a hard error by @v4. The job tried to download
build-artifacts-<verification-id> but no job in the workflow has
ever uploaded an artifact under that name; build-verification only
runs npm pack and uploads nothing.
Fix: build the CLI locally inside the perf job (same pattern the
other jobs use) instead of relying on a phantom artifact. Memory-leak
smoke now probes the v3 cli dist binary with a graceful fallback if
the build skipped — keeps the job informational, not blocking.
