…ing PolicyKernel Generator hardening: - Rewrite puzzle generator with difficulty-based posterior targeting (30-365 day ranges) - Remove InMonth/DayRange over-constraining from low difficulties - DayOfWeek constraint (difficulty 3+) creates 7x cost surface for solver optimization - Distractor injection at difficulty 5+ (redundant constraints that don't narrow search) - target_posterior() scales 300→20 across difficulty 1→10 Solver PolicyKernel: - Add skip_weekday: Option<Weekday> to TemporalSolver - Weekday skipping advances by 7 days instead of 1 when DayOfWeek constraint detected - Wire into AdaptiveSolver for compiler/router modes (B and C) - Mode A (baseline) scans linearly, Mode B/C skip to matching weekdays Correctness: - Relax correctness check: "every expected solution found" (not "only expected found") - Wide posteriors have many valid dates; only target inclusion matters - Integration test step budget increased to 400 for wider ranges Ablation results: - Mode A: 195.96 cost/solve (full linear scan) - Mode B: 68.80 cost/solve (65% reduction via weekday skipping) - Mode C: 68.80 cost/solve (65% reduction, same as B) - B beats A on cost: PASS (65% > 15% threshold) - Compiler false-hit rate: PASS (<5%) - 81 tests passing (61 unit + 20 integration) https://claude.ai/code/session_01RnwD4x5cbpB7FPvoyYQz8G
All modes now share the same solver capabilities. What differs is the policy mechanism that decides *when* to use them: - Mode A: fixed heuristic (posterior_range + distractor_count) - Mode B: compiler-suggested skip_mode from constraint signatures - Mode C: learned PolicyKernel (contextual bandit over skip modes) Key changes: PolicyKernel (temporal.rs): - SkipMode enum: None | Weekday | Hybrid - fixed_policy(): if DayOfWeek AND range>30 AND no distractors → Weekday - compiled_policy(): uses CompiledSolveConfig.compiled_skip_mode - learned_policy(): epsilon-greedy over per-context SkipModeStats - EarlyCommitPenalty: tracks solved-but-wrong from aggressive skipping - Hybrid mode: weekday skip + ±7 day refinement pass for safety DifficultyVector (timepuzzles.rs): - Replaces single-axis difficulty with (range_size, posterior_target, distractor_rate, noise_rate, ambiguity_count) - Flipped relationship: higher difficulty = wider range + more ambiguity (not tighter posterior) - Distractor DayOfWeek (difficulty 6+): DayOfWeek present but paired with wider Between that makes unconditional skipping risky Ablation fairness (acceptance_test.rs): - Removed feature gating: skip_weekday no longer forbidden for Mode A - All modes access same solver knobs, differ only by policy - AblationResult tracks PolicyKernel metrics (early_commit_rate, etc) - Comparison print shows policy differences explicitly 81 tests passing (61 lib + 20 integration). https://claude.ai/code/session_01RnwD4x5cbpB7FPvoyYQz8G

PolicyKernel refinements: - Fixed policy (Mode A): risk_score = R + k*D, k=30, T=140 Fixed constants (not learned) — Mode A is the control arm. One distractor raises perceived risk by ~30 range-days. Weekday only when range is large AND distractor-free. - Normalized EarlyCommitPenalty: (remaining/initial) * scale Committing at 5% scan = cheap (0.05), at 90% = expensive (0.90). Only charged on wrong commits. - Hybrid minimum evidence: stop_after_first disabled in Hybrid mode so solver checks all matching weekdays before committing. Witness log: - SolutionAttempt now carries skip_mode and context_bucket strings - record_attempt_witnessed() for full policy audit trail - Every trajectory records which skip mode was chosen and why Observability: - Puzzle tags now include distractor_count and has_dow (deterministic) - count_distractors() made public for generator to tag puzzles Ablation assertions (two new): - a_skip_nonzero: Mode A uses skip at least sometimes (proves not hobbled) - c_multi_mode: Mode C uses different skip modes across contexts (proves learning) - Skip-mode distribution table printed per context bucket for Mode C posterior_target monotonicity verified: 2→4→8→12→18→25→35→50→70→100 (never shrinks with difficulty) 81 tests passing (61 lib + 20 integration). https://claude.ai/code/session_01RnwD4x5cbpB7FPvoyYQz8G

Fixed policy sign flip (Mode A): risk_score = R - 30*D (was R + 30*D) Distractors now reduce effective range, making Mode A conservative under distractors. This is the defensible control arm: a rational fixed agent should be more cautious when distractors are present. Mode C must learn to outperform this baseline. EarlyCommitPenalty wired into bandit reward: SkipModeStats now tracks early_commit_penalty_sum per arm. reward() includes robustness_penalty = 0.2 * avg_penalty. This means Mode C can actually learn to avoid early wrong commits in distractor-heavy contexts. Previously the penalty was only printed, not optimized. Context buckets expanded to 18: 3 range (small/medium/large) × 3 distractor (clean/some/heavy) × 2 noise (clean/noisy) = 18 buckets. Previous: 4 range × 2 distractor = 8 (too coarse for bandit). Noise flag now flows through AdaptiveSolver.noisy_hint. New ablation assertion: c_penalty_better_than_b: Mode C EarlyCommitPenalty must be ≤90% of Mode B penalty. Proves robustness improvement is explicit, not just noise_accuracy-based. Acceptance test noise plumbing: solver.noisy_hint set to true for noisy puzzles in both training and holdout evaluation. Context buckets now correctly distinguish clean vs noisy conditions. 81 tests passing (61 lib + 20 integration). https://claude.ai/code/session_01RnwD4x5cbpB7FPvoyYQz8G

…path, constraint propagation Replace epsilon-greedy with two-signal Thompson Sampling (safety Beta posterior + cost EMA) for Mode C learned policy. Score = safety_sample - lambda * cost_ema provides principled exploration-exploitation. Add speculative dual-path for Mode C only: when Beta variance > 0.02 and top-2 arms within delta 0.15, run both arms (60/40 budget split) to resolve uncertainty faster while keeping Mode A/B ablation clean. Add constraint propagation pre-pass as PolicyKernel-controlled mode (Off/Light/Full, defaults to Off). Light handles InMonth+DayOfMonth direct solves; Full adds DayOfWeek pruning for ranges ≤60 days. PrepassMetrics tracks pruned_candidates, prepass_steps, scan_steps_saved. Beta sampling via Marsaglia-Tsang Gamma method + Box-Muller normal. https://claude.ai/code/session_01RnwD4x5cbpB7FPvoyYQz8G

…chain Add self-contained acceptance test artifact that external developers can run offline and reproduce identical graded outcomes: - SHA-256-linked witness chain: every puzzle decision (skip_mode, context_bucket, steps, correct) hashed into a tamper-evident chain. Changing any single bit invalidates everything downstream. - Deterministic replay: frozen seeds → identical puzzles → identical solve paths → identical chain_root_hash. Two runs with the same config produce the same hash, proven by test. - JSON manifest: config, per-mode scorecards (A/B/C), all six ablation assertions with measured values, full witness chain, chain root hash. - Verifier: re-runs with same config, recomputes chain, compares root hash. Mismatch means non-identical outcomes. - CLI binary: `acceptance-rvf generate -o manifest.json` to produce, `acceptance-rvf verify -i manifest.json` to verify. 66 lib tests + 20 integration tests pass. https://claude.ai/code/session_01RnwD4x5cbpB7FPvoyYQz8G

…ng improvements Closes five architectural gaps in the learning pipeline: 1. RegretTracker — cumulative regret tracking per context bucket. Measures optimality gap (O(√T) = learning, O(T) = not). Enables convergence detection and learning speed measurement. 2. DecayingBeta — exponential forgetting for non-stationary environments. Old evidence decays by configurable factor per observation. Effective window ≈ 1/(1-decay). Prevents calcification on stale data. 3. PlateauDetector — detects learning stalls with escalating responses: Continue → IncreaseExploration → TriggerTransfer → InjectDiversity → Reset. Compares accuracy windows and tracks consecutive plateau events. 4. ParetoFront — multi-objective optimization replacing single-scalar fitness. Tracks non-dominated solutions across [accuracy, -cost, robustness]. Includes hypervolume indicator, spread metrics, and per-objective queries. 5. CuriosityBonus — UCB-style exploration bonus for under-visited contexts. Bonus = c * sqrt(ln(N) / n_i). Directs exploration toward novel bucket/arm combinations rather than relying solely on Thompson variance. All five compose into MetaLearningEngine, wired into DomainExpansionEngine: - record_decision() feeds regret + curiosity + decaying beta on every arm pick - evolve_population() records kernels into Pareto front before evolution - select_arm_curious() adds curiosity bonus to Thompson Sampling - check_plateau() monitors cost curves for learning stalls - meta_health() provides unified diagnostics Performance (optimized hot paths avoid HashMap clone on existing entries): - RegretTracker: 84ns/record (1k decisions in 84µs) - DecayingBeta: 3ns/update - PlateauDetector: 4.1ns/check - ParetoFront: 67ns/insert, 146ns/hypervolume - Full cycle: 199ns/decision (18% faster after optimization) 82 tests pass. 6 new benchmarks added. https://claude.ai/code/session_01RnwD4x5cbpB7FPvoyYQz8G

NodeBackend.ingestBatch() passed string IDs directly to the N-API layer
via Number(e.id), which returns NaN for non-numeric strings (UUIDs, hex
hashes, etc.). The native Rust HNSW silently drops entries with NaN IDs,
causing silent data loss with no error signal.
Fix: Add a bidirectional string↔numeric mapping layer to NodeBackend,
following the same pattern used by HNSWLibBackend in AgentDB:
- resolveLabel(): allocates sequential i64 labels for string IDs
- query(): maps numeric labels back to original string IDs
- delete(): resolves string IDs to labels before calling native layer
- Mappings persisted to {path}.idmap.json sidecar file
Also fixes query() returning numeric labels instead of original string
IDs, and delete() silently failing for non-numeric IDs.
Bumps @ruvector/rvf from 0.1.9 → 0.2.0 (breaking fix).

There was a problem hiding this comment.
Thanks @salmanmkc. A few concerns on the version bumps:
Action versions that need verification:
actions/checkout@v6— as of Feb 2026, the latest stable isv4. Doesv6exist?actions/upload-artifact@v6— latest stable isv4. Same concern.actions/download-artifact@v7— latest stable isv4.actions/setup-node@v6— latest stable isv4.actions/setup-python@v6— latest stable isv5.
If these tags don't exist on the official repos, the workflows will fail. More critically, if someone creates a fork with those tags, it becomes a supply chain attack vector — the workflow would pull code from an attacker-controlled repo.
Recommendation: Please verify each action version exists on the official GitHub Actions repos before this can be merged. If these are anticipatory bumps for future versions, they should wait until the versions are actually released.
The bumps that look correct:
codecov/codecov-action@v5benchmark-action/github-action-benchmark@v1.20.7(pinned to specific version — good practice)docker/build-push-action@v6peter-evans/dockerhub-description@v5google-github-actions/auth@v3andsetup-gcloud@v3actions-rust-lang/setup-rust-toolchain@v1.15.2(pinned — good)
Could you confirm the @v6/@v7 tags exist on the actions/* repos?

Summary
Upgrade GitHub Actions to their latest versions for improved features, bug fixes, and security updates.

Actions that were previously pinned to commit SHAs remain pinned to SHAs (updated to the latest release SHA) to maintain the security benefits of immutable references.
Testing
These changes only affect CI/CD workflow configurations and should not impact application functionality. The workflows should be tested by running them on a branch before merging.
