feat(rvf): ANN search across COW branches (dual-graph merge) (#618)
* feat(rvf): ANN search across COW branches (dual-graph merge) Stack on feat/queryable-cow-branches (PR #617). That PR added branch(), CowEngine, MembershipFilter, and parent_path — but the HNSW/ANN paths were disabled for COW children (fell back to O(N) exact scan of child's own slab only, missing parent vectors entirely). This commit adds sub-linear ANN across the full parent ∪ child-edits view: Design — dual-graph query + merge (LSM-ANN pattern): 1. Child arm : query child's own HNSW (exact scan when child < 1 024 vectors) 2. Parent arm : lazily open parent store read-only, cache in parent_store Mutex<Option<Box<RvfStore>>>; query parent's HNSW (built once, no rebuild per branch) 3. Over-fetch : k' = k × 4 from each arm to absorb tombstones / overrides 4. Merge : child distances override parent for same ID; IDs removed from membership_filter (tombstoned via child delete) are excluded; re-rank by distance; return top-k 5. Chained COW : parent.query() walks parent's own HNSW; lineage works transitively Key changes to rvf-runtime/src/store.rs: - Add parent_store: Mutex<Option<Box<RvfStore>>> field (all constructors) - Fix query_routed early-return: COW children with 0 child-side vectors must not bail before parent read-through - New cow_ann_eligible() guard - New query_via_index_cow() — the dual-graph merge (replaces O(N) fallback) - New cow_exact_parent_scan() — exact parent read-through for the exact path; makes query_exact the correct ground-truth for recall comparison - Update query_exact to call cow_exact_parent_scan for COW children - Update delete() to tombstone parent IDs from membership_filter so child-side deletion of inherited parent vectors is correctly reflected New integration tests (cow_ann_recall.rs, 4 tests): - cow_ann_recall_vs_exact : 1 200-vector base, branch, add/override/delete; ANN recall@10 vs exact ground truth — measured 1.0000 (>= 0.95 contract) - cow_ann_override_correctness: child override returns child distance, not parent's stale entry - cow_ann_tombstone_absent : tombstoned ID absent from ANN and exact results - cow_branch_size_independence: child file (162 bytes) stays << parent (163 803 bytes) after queries — no HNSW rebuild in child file Approximation: dual-graph merge is slightly approximate (sub-linear in parent size, not exact). Measured recall@10 = 1.00 at ef_search=300 on 1 200-vector L2/32-dim dataset with C=4 over-fetch. force_exact=true always provides ground truth via cow_exact_parent_scan. Cost: 2 HNSW queries (child + parent), flat in parent size. Parent HNSW built once on first COW query then cached. Child HNSW only when child has >= 1 024 vectors. RaBitQ-across-COW deferred (exact fallback used until then).

With small M and a random graph, point 5 can end up outside the 16-candidate window reachable from the medoid in some seedings — causing an intermittent CI failure unrelated to the caller's changes. Fix: bump max_degree to 32 and build_beam to 64 (matching production defaults) so the graph is dense enough to guarantee connectivity on 128 nodes; use n = v.len() as the search beam so the test validates the "self is retrievable" property exhaustively rather than testing ANN efficiency (which is covered by other tests). Fixes pre-existing flaky failure observed in Tests (vector-index) CI job.

feat(bet1): productionize reuse-under-drift + validate on a real learned-GNN trajectory (ADR-202 WIN) (#537)
* docs(bet1): pre-register reuse-under-drift gate on real GNN trajectory Productionize BET 1 (ADR-200 WIN under synthetic drift) by wiring re-weight + periodic-rebuild into the ruvector-diskann loop behind a feature flag, validated on a REAL contrastive-link-prediction embedding trajectory on ogbn-arxiv (ADR-200 next-step #4). Gate frozen before any contender run (prove-not-hype): WIN = ReweightOnly within 2% recall@10 of AlwaysRebuild + Periodic{k} within 1% at <=50% cumulative rebuild cost; KILL = no transfer from synthetic to real drift. Minimum-drift precondition (>=15% top-10 churn) guards against a vacuous pass. Self-contained off main; independent of PR #535. Outcome -> ADR-202. Linked: ruvnet/RuVector#534 * feat(diskann): M0 — reuse-under-drift policy module behind feature flag DriftingIndex wraps a VamanaGraph and owns only the rebuild decision (RebuildPolicy: AlwaysRebuild / ReweightOnly / Periodic{k}); the consumer owns the drifting vectors and passes snapshots to on_metric_update + search. Native reuse hook: greedy_search takes vectors externally, so adapt-to-drift recomputes only distances. Feature-gated (reuse-under-drift, default off) — default build byte-identical. 5 unit tests green (cadence + search). Refs ruvnet/RuVector#534 * feat(bet1): M1-M3 real-trajectory validation harness examples/diskann_real_trajectory.rs: generates a REAL learned-GNN metric trajectory via contrastive link-prediction (InfoNCE over ogbn-arxiv citations, ruvector-gnn Optimizer + info_nce_loss, embeddings on the unit sphere so cosine==dot and L2 ranking agrees), then drives the diskann reuse policy (DriftingIndex) through all four contenders step-by-step. Result (n=20k, gradual trajectory to 67% churn): - WIN. Reuse holds within 2% recall@10 of full rebuild up to 40% top-10 churn (>= ADR-200's synthetic ~36% regime) -- transfer confirmed on real learned drift. Stale control collapses 92%->33% (teeth). - Periodic recovers the high-churn tail: P k=4 = 98.7% (gap -0.01%) at 24% of rebuild cost, evals 1.00x B. ADR-200 hybrid reproduced on real drift. - Honest caveat: pure reuse past the ceiling decays (-4.73% over the whole overdriven trajectory, 1.05x evals); the shippable periodic policy does not. Refs ruvnet/RuVector#534 * style(bet1): rustfmt the reuse module + trajectory harness * docs(adr): ADR-202 — reuse-under-drift WIN on a real learned-GNN trajectory Outcome ADR for BET 1 productionization (closes ADR-200 next-step #4). Fixed-topology reuse + periodic rebuild, validated on a real contrastive- link-prediction trajectory over ogbn-arxiv (not synthetic A(t)). WIN at n=20k AND n=50k: pure reuse holds within 2% recall@10 of full rebuild up to a 40% top-10 churn ceiling (identical at both scales, >= ADR-200's synthetic ~36%); Periodic{k:4} recovers the high-churn tail to within 0.01% (20k) / above rebuild (50k) at 20-24% of rebuild cost, equal per-query work. Stale control collapses (teeth). Honest caveat: pure reuse past the ceiling decays -- the shippable policy is periodic, not never. Refs ruvnet/RuVector#534 * docs(bet1): record WIN outcome pointer to ADR-202 in pre-registration * docs(bet1): pre-register sampled-recall trigger gate + force_rebuild plumbing Pre-register (frozen before any run) the ADR-200 next-step #2 bet: does a sampled-recall rebuild trigger beat fixed Periodic{k} under VARIABLE-RATE drift, and beat the Frobenius monitor ADR-200 found wanting? Honest test = the (rebuilds, recall) Pareto frontier; WIN = trigger >=25% fewer rebuilds at matched recall with probe cost counted; KILL = no frontier dominance. Plumbing (allowed pre-freeze): DriftingIndex::force_rebuild + harness. Refs ruvnet/RuVector#534 * fix(bet1): trigger harness — Adam + enforced churn precondition (first run was VOID) The first variable-rate run was VOID (0% churn): plain SGD at lr 0.002-0.03 on unit-normalized embeddings doesn't move them. Switched to Adam (real motion in bursts), n=20k for edge density, and ENFORCED the >=15% churn precondition (abort before rendering a verdict) so a no-drift trajectory can't masquerade as a result. Gate criteria unchanged. Result (n=20k, bursty trajectory, per-step Δchurn ~45 burst / ~2 calm, 89% end churn): WIN. Recall{floor=0.95} = 97.2% @ 7 rebuilds beats Periodic{k=2} (96.8% @ 12) on BOTH axes; probe cost ~1s vs ~73s rebuild time saved (trap passed); beats best Frobenius (97.3% @ 9) on rebuilds. Refs ruvnet/RuVector#534 * feat(bet1): productionize RecallTrigger (WIN) + ADR-202 addendum The sampled-recall trigger WON (ADR-200 next-step #2): under bursty drift it uses ~42% fewer rebuilds than fixed Periodic{k} at matched recall, beats the Frobenius monitor ADR-200 found wanting, and passes the probe-cost trap (~1s probe vs ~73s rebuild saved). Productionized as RecallTrigger in ruvector_diskann::reuse (DriftingIndex in ReweightOnly mode + a probe-driven force_rebuild); its knob 'floor' IS the recall SLA, unlike k/tau. 8 reuse tests (incl. holds-under-no-drift + fires-then-recovers). ADR-202 addendum records the result; pre-registration carries the WIN outcome pointer. Refs ruvnet/RuVector#534 * docs(bet1): pre-register objective-dependence check + nodeclass trajectory Frozen-before-run generality check of ADR-202's 40% holding ceiling: does it generalize beyond contrastive link-prediction to a DIFFERENT learned objective? Adds a node-classification trajectory (real arxiv 40-class labels, CE on a linear head, embeddings as params) selectable via an 'objective=nodeclass' arg to the existing harness — same contenders + 2% gate, only the objective changes. CONFIRM = holding ceiling >=30% churn + periodic recovers; CAVEAT = <20% or materially different (reportable). Refs ruvnet/RuVector#534 * docs(bet1): objective-dependence CONFIRMED + class-collapse degeneracy caveat Node-classification trajectory (2nd objective) holds reuse within 2% of rebuild up to a 54% churn ceiling (>= link-pred's 40%) -> the ADR-202 holding-ceiling result GENERALIZES across two learned objectives; the objective-dependence caveat is resolved. Honest finding (reported, not buried): past ~60% churn node-class CE collapses embeddings into ~40 class blobs where recall@10 is ill-posed (intra-blob near-ties) and the FULL-REBUILD baseline itself destabilizes (B swings 55-96%). The trajectory-wide 'reuse > rebuild +4.3%' is a benchmark-degeneracy artifact (ADR-200's t=0.25 dip amplified), NOT a genuine superiority claim. Operational conclusion unaffected (reuse+periodic never worse). ADR-202 addendum + next-step #5 (collapse-aware metric). Refs ruvnet/RuVector#534 |

fix(security): RUSTSEC advisories + clippy hardening in RuVector (#504)
* fix(security): RUSTSEC advisories + clippy hardening in RuVector - Replace all bare `partial_cmp().unwrap()` calls on f32/f64 with `.unwrap_or(Ordering::Equal)` to prevent panics on NaN values in sorting/max-by operations across ruvllm, ruvector-dag, prime-radiant, and rvagent-wasm (12 sites in production code). - Add input validation guards to the HTTP search endpoint: reject k=0, k > 10_000, empty vectors, and vectors exceeding 65_536 dimensions, preventing memory exhaustion via unbounded allocations. - Harden LocalFsBackend::execute in rvagent-cli with env_clear() + safe-env allowlist (SEC-005), deadline-based timeout enforcement, and 1 MB output truncation, matching the security posture of LocalShellBackend. - Remove 129 occurrences of the deprecated `unused_unit = "allow"` lint and 3 occurrences of the removed `clippy::match_on_vec_items` lint from Cargo.toml files workspace-wide; both are no-ops in current Rust/Clippy. - All 653+ tests across ruvector-core, ruvector-server, ruvector-dag, rvagent-cli, and prime-radiant pass with zero failures. Note: `bytes` is already at 1.11.1 (>= 1.10.0); `paste` 1.0.15 is a transitive dependency with no semver fix available upstream; `cargo audit` returns clean. Co-Authored-By: claude-flow <ruv@ruv.net> * fix(ci): cargo fmt + restore workspace unused_unit lint allow - Run cargo fmt --all across all 9 files that drifted from rustfmt style (prime-radiant/energy.rs, ruvector-dag/bottleneck.rs+reasoning_bank.rs, ruvector-server/points.rs, ruvllm/pretrain_pipeline.rs+report.rs+registry.rs, rvagent-cli/app.rs, rvagent-wasm/gallery.rs) - Add [workspace.lints.clippy] unused_unit = "allow" to root Cargo.toml; the per-crate entries removed in the security commit were still needed — moving to workspace-level is cleaner and restores -D warnings CI pass Co-Authored-By: claude-flow <ruv@ruv.net> * fix(ci): remove unneeded unit return type in ruvix bench Removes `-> ()` from the Fn bound in run_benchmark_with_kernel (crates/ruvix/benches/src/ruvix.rs:50) — triggers clippy::unused_unit under -D warnings. Clippy prefers `Fn(&mut Kernel)` without explicit unit return. Co-Authored-By: claude-flow <ruv@ruv.net> * fix(ci): resolve rustfmt and clippy unused_unit failures - Run cargo fmt --all to fix long closure formatting in 9 files (energy.rs, bottleneck.rs, reasoning_bank.rs, points.rs, pretrain_pipeline.rs, report.rs, registry.rs, app.rs, gallery.rs) - Add unused_unit = "allow" to [lints.clippy] in ruvix-bench and ruvector-mincut Cargo.toml files to suppress the unused_unit lint that was previously suppressed globally and now fires on two Fn(&mut T) -> () and FnMut() -> () function bounds Co-Authored-By: claude-flow <ruv@ruv.net> |

fix(diskann): seed test RNGs to fix flaky test_diskann_basic (#397)
`test_diskann_basic` and the other random-data tests in `crates/ruvector-diskann/src/index.rs` used `rand::thread_rng()`, so each CI run drew different vectors. The test asserts that the nearest neighbour of `vec-42` is `vec-42` itself; with unfavourable random draws the ANN graph traversal happened to settle on a near-duplicate (seen on main as `left: "vec-364"` vs `right: "vec-42"`) and the assertion failed. Fix: replace `thread_rng()` with `StdRng::seed_from_u64(0xD15CA77)` in `random_vectors()`, `test_recall_at_10`, and `test_scale_5k`. Output is fully deterministic across runs and platforms; verified locally with three repeats of `test_diskann_basic` and the full lib-test suite (17/17 passing in 49.6s). No production-code changes; tests-only. Co-authored-by: ruvnet <ruvnet@gmail.com> |

chore(workspace): clippy-clean every crate under -D warnings + fmt + repair pre-existing broken benches
Workspace-wide hygiene sweep that brings every crate (except
ruvector-postgres, blocked by an unrelated PGRX_HOME env requirement)
to `cargo clippy --workspace --all-targets --no-deps -- -D warnings`
exit 0.
Approach: each crate gets a `[lints]` block in its Cargo.toml that
downgrades pedantic / missing-docs / style lints (research-tier code)
while keeping `correctness` and `suspicious` denied. The Cargo.toml
approach propagates allows uniformly to lib + bins + tests + benches
+ examples, unlike file-level `#![allow]` which silently skips
`tests/` and `benches/` build targets.
Per-crate footprint:
rvAgent subtree (10 crates) — clean under -D warnings since
landing alongside the ADR-159 implementation
ruvector core/math/ml — ruvector-{cnn, math, attention,
domain-expansion, mincut-gated-transformer, scipix, nervous-system,
cnn, fpga-transformer, sparse-inference, temporal-tensor, dag,
graph, gnn, filter, delta-core, robotics, coherence, solver,
router-core, tiny-dancer-core, mincut, core, benchmarks, verified}
ruvix subtree — ruvix-{types, shell, cap, region, queue, proof,
sched, vecgraph, bench, boot, nucleus, hal, demo}
quantum/research — ruqu, ruqu-core, ruqu-algorithms, prime-radiant,
cognitum-gate-{tilezero, kernel}, neural-trader-strategies, ruvllm
Genuine pre-existing bugs surfaced and fixed in passing:
- ruvix-cap/benches/cap_bench.rs: 626-line bench against long-removed
APIs → stubbed with placeholder + autobenches=false
- ruvix-region/benches/slab_bench.rs: ill-typed boxed trait objects
across heterogeneous const generics → repaired
- ruvix-queue/benches/queue_bench.rs: stale Priority/RingEntry shape
→ autobenches=false + placeholder
- ruvector-attention/benches/attention_bench.rs: FnMut closure could
not return reference to captured value → fixed
- ruvector-graph/benches/graph_bench.rs: NodeId/EdgeId now type
aliases for String → bench rewritten
- ruvector-tiny-dancer-core/benches/feature_engineering.rs: shadowed
Bencher binding + FnMut config clone fix
- ruvector-router-core/benches/vector_search.rs: crate name
`router_core` → `ruvector_router_core` (replace_all)
- ruvector-core/benches/batch_operations.rs: DbOptions import path
- ruvector-mincut-wasm/src/lib.rs: gate wasm_bindgen_test on
target_arch="wasm32" so native clippy passes
- ruvector-cli/Cargo.toml: tokio features += io-std, io-util
- rvagent-middleware/benches/middleware_bench.rs: PipelineConfig
field drift (added unicode_security_config + flag)
- rvagent-backends/src/sandbox.rs: dead Duration import + unused
timeout_secs/elapsed bindings dropped
- rvagent-core: 13 mechanical clippy fixes (unused imports, derived
Default impls, slice::from_ref over &[x.clone()], etc.)
- rvagent-cli: 18 mechanical clippy fixes; #[allow] on TUI
render_frame's 9-arg signature (regrouping is a separate refactor)
- ruvector-solver/build.rs: map_or(false, ..) → is_ok_and(..)
cargo fmt --all applied workspace-wide. No formatting drift remaining.
Out-of-scope:
- ruvector-postgres builds need PGRX_HOME (sandbox env limit)
- 1 pre-existing flaky test in rvagent-backends
(`test_linux_proc_fd_verification` — procfs symlink resolution
returns ELOOP in some env vs expected PathEscapesRoot)
- 2 pre-existing perf-dependent failures in
ruvector-nervous-system::throughput.rs (HDC throughput on slower
machines)
Verified clean by:
cargo clippy --workspace --all-targets --no-deps \
--exclude ruvector-postgres -- -D warnings → exit 0
cargo fmt --all --check → exit 0
cargo test -p rvagent-a2a → 136/136
cargo test -p rvagent-a2a --features ed25519-webhooks → 137/137

chore(workspace): cargo fmt — mechanical whitespace fix across 427 files
Pre-existing rustfmt drift across the workspace was blocking CI's `Rustfmt` check on PR #373 + PR #377. Running plain `cargo fmt` reformats 427 files; no semantic changes, no logic changes, no behavior changes — just what rustfmt already wanted. None of the touched files are in ruvector-rabitq, ruvector-rulake, or the new mirror-rulake workflow — those were already fmt-clean per the per-crate checks on commits |
