OceanLi	34390efe56	feat(ruvllm): add lattice as an optional macOS Metal LlmBackend (#642) ... * feat(ruvllm): add lattice as an optional macOS LlmBackend Adds LatticeBackend, a pluggable LlmBackend implementation over lattice-inference's pure-Rust Qwen3.5 Metal GPU forward pass, gated behind a new default-OFF `lattice` feature (macOS-only: dependency under [target.'cfg(target_os = "macos")'.dependencies], module gated #[cfg(all(feature = "lattice", target_os = "macos"))]). - MetalQwen35State (!Send) is owned by a dedicated worker thread, mirroring lattice_serve.rs's spawn_worker/run_worker_loop pattern, but over plain std::sync::mpsc (TokenStream is std-mpsc-backed). - generate_stream_v2 streams every real decoded token via generate_streaming_with_cancel, unlike candle's prefill-only stream stub. - get_embeddings returns RuvLLMError::NotImplemented (honest, per ratified O1) rather than a fake zero vector. - create_backend() precedence: lattice (if enabled) > candle > NoopBackend. Root Cargo.toml carries an uncommitted dev-only [patch.crates-io] pointing lattice-inference at a local checkout; not included in this commit. * fix(ruvllm): enforce stop strings + reject unsupported penalties in LatticeBackend Codex round-1 fixes: - MAJOR 1: lattice's Metal generation loops honor EOS/stop_token_ids but not GenerateConfig::stop_strings, so callers' stop_sequences were silently ignored. Added StopScan: incremental stop-string scanner that holds back the longest possible stop prefix (char-boundary safe), excludes the matched stop from output, and halts generation through the token callback. Both generate (via the streaming loop, so a match actually stops decode) and generate_stream_v2 route through it; no stop strings = zero-overhead path. - MAJOR 2: frequency_penalty/presence_penalty are live ruvllm fields (serving/engine.rs:547, mistral_backend.rs:907), not dead ones; nonzero values now fail fast with NotImplemented instead of being silently dropped. - MINOR 3: em dashes removed from all added lines (repo prose lint). - 6 non-GPU unit tests: StopScan cut/holdback/multi-stop/UTF-8 + penalty rejection on both entry points. * chore(ruvllm): bump lattice-inference to 0.5 * fix(ruvllm): adapt LatticeBackend to lattice-inference 0.5 Result APIs generate and generate_streaming_with_cancel return Result in lattice 0.5; propagate failures as RuvLLMError::Backend on the once path and StreamEvent::Error on the stream path instead of unwrapping. * bench(ruvllm): add lattice_bench example, reproducible backend throughput harness Measures load time, TTFT, and decode throughput for the lattice backend (stream and blocking legs), with a BENCH_GREEDY env toggle so results can be compared against greedy standalone-engine numbers using the same prefill-canceling slope method. The candle backend is timed via blocking generate() only; its generate_stream_v2 emits a single token from prefill logits and is not a decode loop. Feature-gated: builds as a stub without the lattice feature. * docs(ruvllm): model-prep guide for lattice_bench + rustfmt The bench doc header now walks through obtaining a runnable model dir: f16 safetensors straight from HuggingFace, or quantizing with lattice's quantize_q4 and copying tokenizer.json + config.json next to the .q4 output (the quantizer writes weights only). Documents all flags and the BENCH_GREEDY toggle. README points to it from the lattice section. Also applies rustfmt to lattice_backend.rs (import order, comment alignment). * fix(ruvllm): derive safetensors precision label from torch_dtype, not hard-coded Bf16 load_worker_state stamped every safetensors checkpoint as Quantization::Bf16, so an f16/f32 checkpoint got a false precision label in ModelInfo and a wrong bytes_per_weight in the num_parameters estimate. Read torch_dtype from the already-open config.json instead — the same honesty guard lattice_bench.rs applies to the candle side — falling back to Bf16 (the Qwen3.5 release dtype and the previous fixed label) when the field is missing or unmapped, since a label must not fail a load that from_safetensors already accepted. Verified on macOS arm64 (M4, Metal): cargo test -p ruvllm --features lattice green, including the new safetensors_precision_label_follows_torch_dtype test.

rUv	ca8224e0cd	feat(maxsim): add GraphMaxSim centroid-graph variant (salvaged from #622) (#623) ... Adds a fourth MultiVecIndex variant to ruvector-maxsim: a greedy kNN graph over per-document centroids + multi-seed beam search + exact MaxSim rerank. Complements the token-level HnswMaxSim with a one-node-per-document graph. Includes the consecutive-seeding correctness fix discovered in nightly PR #622: step-based beam seeding collapses recall when the step is a multiple of the cluster count. Documented in graph.rs and ADR-252. #622 produced a duplicate ruvector-maxsim crate (the name was already taken by #569, merged 2026-06-15); rather than merge the duplicate, its unique value is salvaged here. The public research gist from #622 remains published. - 5 new tests (recall vs Flat, dim validation, build/empty guards) — 23/23 pass - cargo fmt clean, cargo clippy -D warnings clean	2026-06-29 10:47:01 -04:00

When `boot()` deserialized a manifest it only restored `epoch`, `dimension`, and `profile_id`; the metric always stayed at `DistanceMetric::L2` (the `RvfOptions::default()`). In the COW dual-graph ANN path (`query_via_index_cow`) the parent store is lazily opened via `open_readonly()` → `boot()`. Because `boot()` never restored the metric, every COW child opened its parent with `metric = L2`, even when the store family was Cosine. The parent HNSW was then built with the L2 distance function, and parent query results were L2-ordered distances. Merging those with the child's cosine distances broke the result ordering: cosine recall@10 measured at ≈ 0.10 for 32-dim random vectors. Fix --- * `DistanceMetric` gets two new `pub(crate)` helpers: - `to_id() -> u8`: L2=0, InnerProduct=1, Cosine=2 - `from_id(u8) -> Self`: reverse mapping (unknown → L2, backward-compatible) * The manifest write path (`write_manifest_seg_with_identity`) now encodes the metric into byte [19] of the header (previously a reserved zero). Old stores have 0x00 there → `from_id(0)` == L2 — correct default. * `ParsedManifest` gains a `metric: DistanceMetric` field parsed from byte [19]. * `boot()` restores `self.options.metric = manifest.metric` so every `open()` / `open_readonly()` correctly reflects the stored metric. Before/after recall ------------------- | Path | Before fix | After fix | |---------------------|-----------|-----------| | COW cosine recall@10 | ≈ 0.10 | 1.0000 | | COW L2 recall@10 | 1.0000 | 1.0000 | Regression test --------------- New test `cow_ann_recall_vs_exact_cosine` in `cow_ann_recall.rs` mirrors the existing L2 test with `metric = DistanceMetric::Cosine` and cosine ground truth; asserts recall@10 ≥ 0.95. The L2 test (`cow_ann_recall_vs_exact`) is unchanged and still passes. Follow-on --------- A new `@ruvector/rvf-node` native binding build is needed to ship this fix to the Node.js surface used by agenticow. Until then, agenticow's existing L2-normalize workaround (driving the engine with pre-normalized vectors so L2 and cosine rankings agree) remains correct and safe to keep.

rUv	afcaf07669	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.

rUv	bc1875bcfa	feat(rvf): queryable COW branches — wire CowEngine read-through to query path (#617) ... * feat(rvf): queryable COW branches — wire CowEngine read-through to query path RVF's COW branch was created but not queryable: a derived/branched child returned only its own edits, never the inherited parent vectors. This wires parent read-through into the exact query path and exposes the real COW branch() through the node binding. Root cause (confirmed against source): - The node binding's derive() (rvf-node/src/lib.rs) called store::derive() which builds a child with cow_engine: None — a lineage/provenance delta, not a COW union. - The real COW path, branch() (store.rs), wires CowEngine::from_parent + a MembershipFilter, but was never exposed in the node binding. - query_exact()/read_path scanned only self.vectors (local edits). The cow_engine/membership_filter were consulted ONLY to *disable* the HNSW / RaBitQ fast paths (index_eligible/rabitq_eligible), never to merge parent data. CowEngine::read_vector/read_cluster were never called from the query path. - query_routed() additionally short-circuited to an empty result whenever self.vectors.len() == 0, so an unedited COW child returned nothing. - The existing cow_branching test asserted only MembershipFilter membership; it never ran a query, so the gap went unnoticed. Fix (exact-scan read-through slice): - store.rs: query_exact() now performs a COW read-through. For a COW child it lazily opens a read-only handle to the parent (cached in a new parent_store field), then merges every inherited parent vector that the child has not overridden (re-ingested locally) or deleted into the same bounded-heap scan — i.e. parent ∪ child-edits with the child winning on an id collision. Factored the heap admission into heap_consider(). - store.rs: query_routed() no longer short-circuits empty for COW children. - store.rs: branch() now sizes the MembershipFilter by max-id+1 (not the vector count) so sparse / non-contiguous ids are representable. - rvf-node/src/lib.rs: expose branch() (COW-enabled) alongside derive(). Scope: this is the EXACT (flat) read-through slice. The byte-level CowEngine::read_cluster path addresses raw cluster offsets, which do not correspond to RVF's segmented on-disk layout, so it cannot be wired to a real .rvf parent as-is. ANN-index (HNSW/RaBitQ) read-through across the COW boundary remains a follow-up; those paths already fall back to the exact scan for COW children, so correctness holds. Test: new branch_query_reads_through_to_parent — builds a 1k-vector base, branches a COW child, applies edits, and asserts (1) a query for a base vector returns it via read-through, (2) a query for an edited vector returns the child's override, (3) a newly added child vector is queryable, and (4) the branch file stays far smaller than the base (COW delta, not a full copy). All 9 cow_branching tests and the full rvf-runtime + rvf integration suites pass. Discovered via RVF-COW benchmarking in the agent-harness-generator (MetaHarness) project, which proved the branch was a lineage-only delta and pinpointed the unexposed branch() + unwired read path.

rUv	3ae7e5f862	fix(graph-node): batchInsert nodes missing from label index (#616) ... * fix(graph-node): batchInsert nodes missing from label index batchInsert only populated the hypergraph adjacency/vector index (used by kHopNeighbors and stats) but never inserted nodes into the property graph + label index that the Cypher `MATCH (n:Label) RETURN n` scan reads. As a result, the fastest ingest path produced query-invisible nodes: they were counted in stats() and traversable by kHopNeighbors, but a label-scoped MATCH returned 0. createNode did both; batchInsert did not. Extract the shared index-registration logic into a single `register_node` helper (single source of truth) and call it from both createNode and batchInsert so the hypergraph index, property graph + label index, and optional storage all stay consistent. batchInsert now also honors per-node labels/properties (previously ignored). Adds a Rust regression test asserting that nodes registered via the shared path are consistently visible through all three read surfaces: label-scoped scan (get_nodes_by_label), kHop adjacency (k_hop_neighbors), and stats() entity counts.

Benchmark: a single weight vector trained on a sequence of tasks (no replay, auto-detected boundaries) — the canonical plasticity-vs-forgetting frontier. Darwin (GA + coordinate-descent polish) evolves the genome on TRAIN task- sequences; results reported on HELD-OUT sequences (different seeds). Measured (deterministic), held-out: the evolved config beats EwcConfig::default() (the crate's hand-tuned 'OPTIMIZED' values) by 35% lower final loss and 98.6% less forgetting — a strict Pareto win (plasticity also improves), and it generalizes to unseen task sequences. clippy -D warnings clean, fmt clean.

Key finding (sharpens the idea): 'selection prunes overfit adapters' holds ONLY under per-domain evaluation. Measured (held-out, in-dist-majority eval): overfit α=0.55 → ΔA +0.249 / ΔB -0.357 (regresses out-dist) AGGREGATE (volume-weighted) fitness → picks the overfit adapter (silent B regression) PER-DOMAIN (no-regression Pareto) → prunes it, keeps the generalizing adapter So: evolve the adapter as a gene, but score it per-repository. clippy/fmt clean. Co-Authored-By: claude-flow <ruv@ruv.net> * docs(adr): ADR-271 metaharness-Darwin for SONA self-improvement Documents the metaharness-Darwin-evolves-SONA architecture: EWC++ config evolution (PR #615), the weightAdapter gene (per-domain Pareto selection of fine-tuned adapters), the Autonomous Data Engine (execution-verified SWE-bench trajectories -> DPO pairs), and four Ornith-1.0 borrows (immutable-boundary + deterministic-monitor-with-exclude-from-advantage + frozen-LLM-judge-veto reward-hacking defense; per-task-category specialization; two-stage scaffold reward credit; staleness-weighted replay). Method-not-model: external evolutionary vs Ornith's in-weights RL. Co-Authored-By: claude-flow <ruv@ruv.net> * feat(sona): darwin-guard reward-hacking defense (Ornith-1.0 borrow, ADR-271) 3-layer defense for evolutionary config search: (1) immutable verifier boundary (screen is a pure fn of verifier output the candidate can't fabricate); (2) deterministic monitor — non-finite / out-of-bounds / degenerate candidates are EXCLUDED from selection (best_accepted), not zero-scored, so a hack can neither win nor bias the advantage; (3) IntentJudge trait = frozen-LLM veto-only layer. Wired into darwin_ewc: NaN/collapsed configs are excluded from the GA ranking (also fixes the partial_cmp().unwrap() NaN-panic). 4 unit tests; benchmark still reaches beyond-SOTA (35% lower loss, 98.6% less forgetting) unchanged. clippy -D warnings + fmt clean. Co-Authored-By: claude-flow <ruv@ruv.net> * feat(sona): per-task-category genome router beats single global config (ADR-271) Ornith-1.0 borrow #2 (per-category specialization): evolve a router task-class -> genome instead of one global EwcConfig. Two continual-learning workload classes with conflicting optima (STABLE wants high lambda / retain; VOLATILE wants low lambda / stay plastic). Guard-screened evolution. Measured (held-out, adequate per-class data): per-category router 0.1122 vs single best global genome 0.1144 -> router ~1.9% better on unseen sequences, because one config cannot serve conflicting workloads. Honest caveat (discovered + documented): the gain REVERSES when per-class data is scarce — a specialized config overfits while the pooled global generalizes. Per-category routing needs enough per-category samples (Ornith's regime). ADR-271 updated; clippy/fmt clean. Co-Authored-By: claude-flow <ruv@ruv.net> * feat(sona): online auto-tuner with staleness-weighted replay (ADR-271, Ornith borrow #4) auto_tuner module: StalenessSchedule (Ornith w(d_t): fresh<=k1, exp-decay, drop>k2) + StalenessWindow (staleness-weighted running estimate of recent config performance, evicts stale obs). 4 unit tests. examples/darwin_autotuner: a (1+1)-ES that adapts a DEPLOYED EwcConfig to a drifting workload stream (regime A -> B at the midpoint), scoring the incumbent on the staleness window and accepting a perturbation only when it beats the recent score. Measured: online tuner ~3% lower post-drift loss than the static deployment config (10 accepted re-tunes). Margin is modest on synthetic regimes; the durable win is the reusable staleness machinery + the online-adaptation principle (a fixed offline-tuned config goes stale under drift). Completes the four ADR-271 components. clippy --all-targets -D warnings + fmt clean; 102 sona tests pass. Co-Authored-By: claude-flow <ruv@ruv.net> * feat(sona): contamination/disjointness guard in darwin-guard (weight-eft/ADR-198 borrow) Adds the train/eval contamination guard — the gap @metaharness/weight-eft exposed in our reward-hacking-only guard. contamination()/assert_train_eval_disjoint() fail on any train∩eval instance-ID overlap (training/selecting on eval instances is fake lift); filter_holdout() partitions a set disjoint-by-construction and surfaces what was excluded. The SONA-side analog of weight-eft's assertTrainEvalDisjoint. 2 new tests (6 total in darwin_guard). ADR-271 updated: §3 Data Engine now cites @metaharness/weight-eft + adopts its RLHF-correct recipe (SFT distills ALL gold incl. off-policy frontier successes; DPO ON-POLICY cheap-vs-cheap only), and the darwin-guard borrow gains layer (iv) the contamination disjointness guard. clippy -D warnings + fmt clean. Co-Authored-By: claude-flow <ruv@ruv.net> * chore(release): ruvector-sona 0.2.1 — darwin_guard + auto_tuner modules Non-breaking minor feature release (new public modules darwin_guard, auto_tuner).

rUv	48dbbb663c	chore(release): publish timesfm + ruvector-timesfm 2.2.4 (#613) ... timesfm gained quantization/f16/select_device/serde after 2.2.3 was published; bump to 2.2.4 and publish so ruvector-timesfm (new crate, uses those APIs) can depend on it.

rUv	a437ffd034	feat(timesfm): real-model tests + GPU/batch optimization + ruvector-timesfm crate + metaharness (#608) ... * feat(timesfm): GPU/device optimization + ruvector-timesfm integration crate timesfm: - cuda/metal features now imply candle (so `--features cuda` alone compiles the numeric path); add timesfm::select_device() (TIMESFM_DEVICE=cpu|cuda|metal) and use it in the bench instead of hardcoding Device::Cpu. - Validated real-weight decode on RTX 5080: 45.2 ms (CPU) -> 3.97 ms (cuda) = ~11.4x, parity preserved (max-abs 8.58e-6). Note: decode at h<=128 is a single forward pass (horizon_len=128), so KV-cache is a no-op there; GPU/f16 are the real levers. Derive serde on PruneDecision for the MCP boundary. ruvector-timesfm (new crate): RuVector-facing integration. - Forecaster: load-once, forecast(series, horizon) -> point + calibrated p10..p90 quantile bands. - anomaly: forecast-band detection (flag observed points outside their p10/p90). - sweep::EarlyStopper: ADR-191 TimesFM-driven early-stopping for ruflo/Darwin sweeps (wraps prune::decide_prune with min_history + confidence gate). - ruvector-timesfm-forecast: JSON-in/out CLI = the time_series_forecast MCP tool entry point. - telemetry_anomaly example (flags injected spikes on real weights), integration tests (5 candle + 3 pure-logic, all green; gated/skip without 814MB weights). clippy --all-targets -D warnings clean (both feature states); fmt clean. Co-Authored-By: claude-flow <ruv@ruv.net> * feat(harness): add generated timesfm metaharness bundle (ADR-041) Authentic output of the agent-harness-generator (create-agent-harness v0.2.7, kernel 0.1.2) synthesizing an engineering-pod harness for the TimesFM forecasting crates. Template vertical:coding (the generator's recommended rust-crate-harness archetype); host claude-code. - score: scaffoldReady, 6/6 hard constraints, toolSafety 100, compileConfidence 90 - genome: repo_type rust, topology maintainer/tester/security, risk 0.37, mcp_surface local_default_deny - witness: .harness/manifest.sha256 over .harness/manifest.json, verified valid (7c45ab91…). PROVENANCE.md records the repro command, score, genome, witness, and the link to the time_series_forecast MCP tool (ruvector-timesfm-forecast). Co-Authored-By: claude-flow <ruv@ruv.net> * feat(ruvector-timesfm): batched forecasting (throughput path) Forecaster::forecast_batch forecasts B equal-length series in one model call. Measured on real weights (B=32, ctx=256, h=64): - CPU: 27 -> 166 forecasts/s (6.16x), bit-exact vs per-series - cuda: 244 -> 2078 forecasts/s (8.45x), rel diff 1.7e-4 (GPU reduction order) Adds the throughput example (sequential vs batched + correctness check with a relative tolerance for GPU) and a real-model batch-parity integration test. Co-Authored-By: claude-flow <ruv@ruv.net> * feat(harness): Darwin evolve via OpenRouter, key sourced from GCP Secret Manager Adds scripts/evolve-openrouter.{sh,mjs} to optimize the timesfm-harness with Darwin Mode's OpenRouter LLM mutator (library-only; not CLI-exposed). The OpenRouter API key is fetched from GCP Secret Manager at runtime (gcloud secrets versions access OPENROUTER_API_KEY, project cognitum-20260110) and exported only into the run's process — never stored in the repo/dotfile/logs. Driver resolves @metaharness/darwin (devDependency) or DARWIN_DIST for local monorepo runs. Validated: real-sandbox evolve (1 gen x 2 children, google/gemini-2.5-flash) scored baseline 0.985 with safety 1.0 and zero secret-exposure flags; ~$0.003. Mutations pass the validateGeneratedCode gate and only promote on measured improvement. PROVENANCE.md documents usage. Co-Authored-By: claude-flow <ruv@ruv.net> * feat(timesfm): int8/int4 weight quantization (QLinear + load_quantized) Adds QLinear (full-precision or ggml-quantized weight via QMatMul) threaded through the decoder; PatchedTimeSeriesDecoder::load_quantized(cfg, vb, dtype) quantizes the 2 ResidualBlocks + 20 transformer layers (embeddings/norms/scaling stay f32). Exposed as Forecaster::load_quantized(.., Quant::Q8_0|Q4_0). Measured on real weights (CPU, ctx=512/h=128) — quant is a MEMORY win, not a CPU-speed win (dequant overhead dominates the small 16-patch matmuls): f32 : 46 ms 814 MB Q8_0 : 242 ms ~212 MB (4x smaller) rel err 3.5e-3 (recommended) Q4_0 : 246 ms ~112 MB (7x smaller) rel err 3.1e-2 All outputs finite. f32 path unchanged (QLinear::Full == prior Linear; parity still 8.58e-6). quant_bench example + Q8_0 integration test added. Co-Authored-By: claude-flow <ruv@ruv.net> * feat(ruvector-timesfm): forecast-driven HNSW rebuild scheduler (vector-db hook) rebuild module: forecast an index's recall-drift curve with TimesFM and advise WHEN to rebuild — schedule the rebuild to land just before the conservative (p10) recall forecast crosses a floor, instead of fixed-schedule or after-the-fact. Forecaster::advise_rebuild(recall_history, floor, horizon, lead_steps) -> RebuildAdvice{rebuild_now, steps_until_floor, ...}. Ties into the ruvector-diskann recall-trigger work. Pure-logic + real-model tests. Co-Authored-By: claude-flow <ruv@ruv.net> * feat(timesfm): f16-on-load path (Forecaster::load_f16) + GPU bench Run the forward in f16 (f16 weights/activations). Three localized dtype fixes make the path f16-clean (attention mask coerce, decode padding dtype, RevIN scalar-extraction slices); the f32 path is untouched (parity still 8.583e-6). Forecaster gains a dtype field + load_f16; forecast/forecast_batch build inputs in the load dtype and surface f32 to callers. Measured RTX 5080 (B=32, ctx=256, h=64): batched f32 2082 -> f16 3261 forecasts/s (1.57x), sequential 238 -> 303/s. f16 forecasts within rel 2e-2 of f32. (CPU f16 is slower, like quant — GPU is where f16 pays off.) f16 + Q8 remain the two precision knobs: f16 for GPU latency, Q8_0 for edge memory.

Behind an opt-in `candle` feature (default = [], cpu-fallback pattern like ruvector-hailo); no lockfile churn (candle 0.9.2 already pinned by ruvllm). - config.rs: TimesfmConfig (1280 dim, 20 layers, 16 heads, 80 head_dim, patch 32/128) - model.rs: ResidualBlock patch embedding, sinusoidal pos-emb (no RoPE), 20x decoder (fused qkv, learnable per-head-dim softplus scaling, causal+padding mask), RevIN instance norm, forward [B,N,128,10] + autoregressive decode to arbitrary horizon - scripts/convert_weights.py: HF safetensors → VarBuilder key remap (--dry-run) - 12 tests (shape + RevIN numerical regression); clippy -D warnings clean Adversarial review caught + fixed a real RevIN bug (masked_mean_std did a global mean/std instead of the reference's first-qualifying-patch selection) + added regression tests. Honest scope: dimensionally + structurally faithful, but real numerical weight-parity vs the published safetensors is NOT yet verified (tests run on dummy weights). Open low-impact faithfulness deviations documented in code. Co-Authored-By: claude-flow <ruv@ruv.net> * style(timesfm): rustfmt the crate (format the RevIN-fix edits) — green the Rustfmt gate for this crate Our crate is now fmt-clean + clippy-clean; the remaining workspace-wide fmt diffs are pre-existing in other crates, out of scope for this PR. Co-Authored-By: claude-flow <ruv@ruv.net> * feat(timesfm): weight-parity validated against official PyTorch reference Drives the candle TimesFM 1.0 200M port from "compiles on dummy weights" to a real numerical PASS against google/timesfm-1.0-200m. Measured (f32 CPU, deterministic 512-pt series, horizon 128): max-abs-diff = 8.58e-6 MAE = 3.25e-6 rel-error = 5.83e-7 (target was <1e-2; we hit the f32 accumulation floor ~1e-5.) Bridge: the real torch_model.ckpt state_dict (253 keys) maps 1:1 through scripts/convert_weights.py with zero unmapped/missing keys. Bug found + fixed (src/model.rs build_mask): the attention mask used f32::NEG_INFINITY for masked positions. With real 0/1 paddings the padding term `padding * -inf` computes `0 * -inf = NaN`, poisoning the whole mask so softmax emitted NaN for every row (every forecast value was NaN). The old `nan_to_zero` guard silently failed (where_cond dtype mismatch -> fallback `NaN * 1 = NaN`). Replaced with the reference's large *finite* negative (-0.7 * f32::MAX) and element-wise `minimum` merge, exactly matching convert_paddings_to_mask + causal_mask + merge_masks. No NaN, exact parity. Added: - examples/parity.rs end-to-end parity runner with metrics + verdict - tests/parity.rs gated integration test (skips cleanly w/o the 814MB artifacts; never fabricates a pass) - scripts/gen_reference.py reference forecast generator (official decoder) Co-Authored-By: claude-flow <ruv@ruv.net> * bench(timesfm): forward-only latency bench — 45ms/forecast (200M, ctx512/h128, warm CPU); parity validated 8.58e-6 * feat(timesfm): predictive-pruning module for Darwin (ADR-191 §2) Add crates/timesfm/src/prune.rs: forecast an optimization curve's plateau from its first K points with TimesFM and decide PRUNE vs CONTINUE against a viability threshold (lower=better, like exploitability). Decoupled — operates on a generic Vec<f32>, no cross-repo poker-darwin dep. - decide_prune(): forecast tail to target horizon, plateau = mean of last horizon/4 steps; PRUNE iff plateau > threshold. Guards: non-finite forecast => CONTINUE conf 0 (never kill on a broken forecast); already-viable (best_so_far <= threshold) => CONTINUE. Scale-invariant confidence. - examples/predictive_prune.rs + tests/prune.rs: two synthetic curves with REAL weights — doomed (floor 0.20) => PRUNE (forecast plateau 1.98, conf 0.72); healthy (already below 0.05) => CONTINUE. Both decisions correct. Skips cleanly when weights absent (no fabricated pass). - Honest calibration note: TimesFM mean-reverts upward on short synthetic decays so absolute plateau is biased high; decision rides the robust relative-ordering + already-viable signals, not absolute calibration. - Doc-comment shows how poker-darwin calls this on its champion curve. Tests: 12 shape + parity + prune = 14/14 green (candle); light build green.

Add [[example]] required-features = ["candle"] so they are skipped when the feature is off, matching parity/predictive_prune which already self-gate via #[cfg(feature = "candle")]. Co-Authored-By: claude-flow <ruv@ruv.net> * fix(maxsim): add ruvector-maxsim to workspace + make clippy-clean The research-nightly CI shard referenced -p ruvector-maxsim (added 578400d1d, 2026-06-21) but the crate was never a workspace member, so the shard aborted with 'package ID ruvector-maxsim did not match any packages' before reaching the timesfm candle test step in the same shard. Add the crate to workspace members so the shard resolves and timesfm tests actually run. The crate's self-imposed #![warn(missing_docs)] plus an unused param and a dead ground_truth() helper would otherwise fail the workspace 'Clippy (deny warnings)' job once it's a member, so: document the public error/types fields, underscore the unused gen_corpus dims param, and drop the dead ground_truth() (main builds ground truth inline). cargo clippy -p ruvector-maxsim --all-targets -- -D warnings is clean; 19 tests pass. Co-Authored-By: claude-flow <ruv@ruv.net> * fix(clippy): clear pre-existing workspace clippy + fmt debt under -D warnings The timesfm candle compile error was masking the rest of the workspace from 'Clippy (deny warnings)' (cargo clippy --workspace --all-targets -- -D warnings); once timesfm/maxsim compile, these pre-existing lints (also red on main) surface. All trivial, no behavior change: - proof-gate: needless &seq.to_le_bytes() borrows (hash bytes identical via AsRef), allow items_after_test_module, allow dead queries field in example - photonlayer-wasm: swap approx-PI 3.14 test literal for 2.5 (arbitrary fill) - coherence-hnsw / gnn example: allow(needless_range_loop) where index is reused - gnn / hnsw-repair: allow(too_many_arguments) on bench fns; sort_by->sort_by_key; &mut Vec -> &mut [_] - graph bench: drop black_box around unit validate_node().unwrap() - sota-bench: drop unused imports, .max().min()->.clamp(), remove redundant parens - maxsim: rustfmt + Cargo.lock sync (now a workspace member) cargo clippy --workspace --all-targets --no-deps -- -D warnings: clean (exit 0) cargo fmt --all -- --check: clean (exit 0) Co-Authored-By: claude-flow <ruv@ruv.net> * fix(deny): ignore RUSTSEC-2026-0186 (memmap2 unsound, transitive) cargo-deny's advisories check fails on RUSTSEC-2026-0186 — an 'unsound' (not exploitable) Unchecked-pointer-offset advisory against memmap2 0.9.x, pulled transitively via safetensors/candle mmap loading and other crates. No fixed 0.9 release exists yet and we don't pass attacker-controlled offsets to memmap2. Add it to the justified ignore list (re-review 2026-08-01), matching the existing deny.toml pattern.

Core (crates/sonic-ct, pure Rust, zero deps, 17 tests): - procedural z-varying torso phantom (fat/muscle/organ shells, spine, ribs, pelvis, liver/spleen/kidneys/aorta, heart+lungs in thorax) - circular ring acquisition with straight-ray travel-time + attenuation - SART time-of-flight reconstruction (1 sweep == delay backprojection) - transparent speed-band segmentation with per-cell uncertainty - coordinate-ascent threshold training (mean Dice ~0.30 -> ~0.63) - RuVector-style acoustic memory: NSW vector index, longitudinal drift, warm-start, anatomical graph-coherence checks, .rvf-style serialization - 3-D volume sweep (truth / recon / error / confidence channels) - mock Butterfly Embedded acquisition boundary (trait, no hardware SDK) WASM (crates/sonic-ct-wasm): raw C-ABI cdylib (no wasm-bindgen, ~39 KB) exposing the single-slice + progressive volume pipeline. UI (examples/sonic-ct): React Three Fiber "Sonic Chamber" — water chamber, transducer ring(s), holographic torso with internal organ glows and class-tinted contour slices, live HUD (acoustic paths, phantom fidelity, path confidence, body composition), cranio-caudal scrubber. Driven entirely by real reconstruction data. Docs (docs/sonic-ct): 8 ADRs, SOTA research map, market brief, SPARC. Co-Authored-By: claude-flow <ruv@ruv.net> Claude-Session: https://claude.ai/code/session_01Mx4vKMfvsq5KBQgPRSoxM7 * feat(sonic_ct ui): welcome modal + GLB body-model loader with procedural fallback - WelcomeModal: Simulate/Reconstruct/Analyze/Validate intro, Get Started cards, "show on startup" preference, research-only disclaimer. - BodyModel: loads a supplied GLB anatomy model (GLB_URL) and applies a ghost material override + per-organ tinting from organ_manifest.json; cleanly falls back to the procedural violet ghost (torso + internal organ glows) when no asset is supplied or it fails to load. GLB is a visual prior only — the Rust phantom stays the physics ground truth. - Refined holographic ghost: violet volumetric glow, class-tinted contour slices, twin transducer rings, glowing base, internal organ volumes. - docs/sonic-ct/BODY-MODELS.md: researched model sources (Zygote, BioDigital, SMPL/Meshcapade, Z-Anatomy, BodyParts3D) + GLB integration pipeline.

Organ inference (ADR-0009/0010): new `crates/sonic-ct/src/organ.rs` detects liver, spleen, kidneys, aorta, heart, and lungs from the reconstructed volume using anatomical priors (zone, side, size, posterior adjacency, slice-consistency) — never from speed alone. Each hypothesis carries a confidence and an evidence bitmask. Exposed via WASM (sct_organ_*, sct_quality_flag) and surfaced in a new HUD panel with per-organ confidence bars + quality flags (bone shadowing / sparse coverage / boundary uncertainty / gas). 18 Rust tests pass; clippy clean. Harness optimization (examples/sonic-ct/optimize.mjs): uses @metaharness/darwin ("freeze the model, evolve the harness") with cheap->frontier tiering and Pareto selection over the frozen WASM engine to evolve {elements, fan, iters}; lifts phantom fidelity ~0.53 -> ~0.59.

Real CT slices are calibration targets, not USCT. - benchmark.mjs: 3-section report (synthetic / real region-level / governance); headline separates speed from real fidelity. Real slices now classify as exclude/researchOnly and stay out of headline metrics (abdomen~0.30). - evidence:refresh (OpenRouter): grades modality evidence into docs/evidence/*.md + a candidate cache; promotion to the curated cache stays a reviewed step. Live run graded acoustic USCT = C (research-only), MRI = B. - CI gates (ciGates.test.ts + .github/workflows/metabiohacker-ci.yml): residual invariant, pathology review forced, A/B-only claims, real-slice honesty gate. 23 metabiohacker tests + 12 Rust integration tests pass.

Low frequencies recover the smooth background first, keeping high-frequency stages out of local minima. Proven by a third FWI test: frequency continuation lowers the inclusion-region error below single-scale FWI at matched iteration count (deterministic).

Wrap the agentic-time layer of the dependency-free `emergent-time` crate in a tiny wasm-bindgen surface for the browser, edge, and Node. - crates/emergent-time-wasm: standalone cdylib (workspace-excluded so it carries its own opt-level="z" / lto / strip / panic=abort release profile and dlmalloc global allocator, mirroring crates/rvf/rvf-wasm). Hand-rolled getters, no serde, to keep the wasm tiny. - SDK surface: AgenticClock (tick → explainable Tick{class,reason,deltaTime, per-channel}; cumulativeTime, ATI, 7-state health), StateDelta, Tick, TickClassJs, AgentHealthJs, WindowedDeltaClock + PageHinkleyDetector change-point detectors, LearnedWeights inference, version(). - Physics core (Wheeler-DeWitt / Page-Wootters / entropic / thermal / Structural Proper Time) deliberately not wrapped: dense matrices don't serialize cheaply over the JS boundary and would bloat the wasm. Documented in the README. - npm/packages/emergent-time: package.json (@ruvector/emergent-time@0.1.0, ESM, main/module/types → pkg, files include pkg + README, publishConfig public), detailed README, build.sh pipeline (cargo @1.89 → wasm-bindgen --target web → wasm-opt -Oz with bulk-memory/nontrapping-float-to-int enabled), and the built pkg/ (wasm + JS glue + .d.ts). Validation: wasm raw 62475B / opt 55009B (wasm-tools VALID); Node ESM smoke test passes end-to-end (AgenticClock Healthy→Drifting→NeedsReplan→Collapsing→ NeedsHumanReview, cumulativeTime 19.36, both detectors fire at the planted jump); tsc --noEmit --strict on a usage example against the shipped .d.ts exits 0; npm pack --dry-run lists README.md + .wasm + .js + .d.ts. Honest scope (mirrors ADR-251): the agentic clock is a diagnostic signal; it does not establish an early-warning lead over a fair baseline on real traces.

Darwin score ranking shows rabitq-flat-f32 at darwin=0.997 as top candidate for evolution pressure (correct: exact search is the evolution target). sota_all.rs now runs all 5 families: core-hnsw (4 ef values) | rabitq (3 variants) | lsm-ann | matryoshka | hybrid Next: HDF5 real-data run (needs --features real-datasets), then open PR.

Piotr Sienkiewicz	11e269a6dc	feat(rvf-runtime): public read_all_vectors / iter_vectors on RvfStore (#557) ... query() returns only (id, distance) (SearchResult), and the (id, vector) reader (VectorData / read_vec_seg_payload) was pub(crate) — so there was no public way to read vectors back out of an opened store. Adds two methods on RvfStore: - iter_vectors() -> impl Iterator<Item = (u64, &[f32])> (lazy, zero-copy) - read_all_vectors() -> Vec<(u64, Vec<f32>)> (owned convenience) Both skip deleted ids, matching query() visibility. No format change and no new IO path — exposes what is already materialized in memory (mirrors the existing walk in query_with_envelope). Unblocks external cache backends (e.g. ruLake's BackendAdapter) priming a quantized index without re-encoding. Test included.	2026-06-21 18:57:21 -04:00

Learned mask EER 0.001 vs random 0.133; optical capture reduces reconstruction PSNR vs identity. photonlayer-cli: bench / barcode / edge / privacy-gate / verify-receipt demos with ASCII frame rendering. Barcode decodes all 4 classes from non-human-readable frames; privacy-gate emits a verifying RVF receipt. Clean build, zero warnings.

Enforced in OpticalField:: from_image (pre-allocation) and in the WASM run_trace boundary (dimension guard + config.validate) to block allocation-DoS and 32-bit usize overflow from a malicious config_json. +2 core tests (now 23).

Measured: at 64x reduction learned=0.988 vs random=0.738. - Fix photonlayer-wasm useless-comparison lint -> meaningful monotonicity check. * perf(photonlayer): M1 — cached + in-place Propagator (1.70x, bit-identical) Hot-path optimization for the mask-learning loop, which propagates thousands of fields through one fixed config. The config-only transfer function H was recomputed on every call, and every propagate() cloned the field buffer. - Propagator precomputes H once per (config,w,h); propagate_into() runs the forward FFT -> xH -> inverse FFT in place (no per-call clone). - Output is bit-for-bit identical to the free propagate() (asserted in cached_propagator_is_bit_identical, always-on). - Measured 1.70x over the naive path at 64x64 x3000 (release): naive=615ms -> cached+inplace=361ms. Proof is an --ignored timing test (debug wall-clock is meaningless); correctness gate runs in the default suite. Also lands: - ADR-263 PhotonLayer FiberGate (transmission-matrix MMF backend; receipt- verified, NOT zero-knowledge; non-square T; nalgebra column-major contract). - docs/research/photonlayer/APPLICATIONS.md — task-trained-sensors positioning, application areas, viral demos, product path, platform acceptance test. Co-Authored-By: claude-flow <ruv@ruv.net> * feat(photonlayer): real-data MNIST optical-compression benchmark + differential ablation (M2) Adds an honest, reproducible real-data benchmark for the learned optical frontend (ADR-260 M2), replacing the synthetic-only 4-class evaluation that ADR-260 itself flagged as a scientific-integrity risk. New modules (photonlayer-bench): - mnist.rs : parses raw uncompressed IDX (verified magic 0x803/0x801), downsamples 28x28 -> 20x20 centered in a 32x32 power-of-two optical grid. Dataset is fetched once into a gitignored cache (NOT vendored); loader has zero network/decompression deps. - diffdetect.rs: differential-detection readout (Li/Ozcan arXiv:1906.03417) - 10 positive + 10 negative detector regions, score I+_k - I-_k. - mnist_bench.rs: trains one phase mask (seeded block hill-climbing) and runs the full acceptance comparison + ablation on the IDENTICAL mask. Integration test (mnist_differential_bench.rs, NOT a standalone bin to avoid the CrowdStrike AV os-error-5 on fresh exes): fast always-on smoke guard + #[ignore] heavy run with a documented command. Measured (deterministic, seed 0x6e157, 4000 train / 2000 blind test, balanced): full-image baseline (1024 px, 10240-param centroid) 0.7540 optical compressed ( 64 px, 640-param centroid) 0.7420 delta vs baseline -0.0120 (PASS, allows -0.02) sensor pixel reduction 16.0x (>= 16x) digital MAC reduction 16.0x (>= 10x) learned vs random mask (decoded) +0.0925 ACCEPTANCE (user's relative-to-baseline test): PASS. Honest caveats reported in-table: this is a SINGLE hill-climbed phase mask + tiny decoder (single-layer optical compression). The Li/Ozcan ~97% MNIST figure is a 5-layer diffractive net trained end-to-end by backprop with differential readout as the final layer; multi-layer + gradient is future work. The optics-only argmax differential lever is reported as a transparency floor (the mask is trained for the decoder readout, not the argmax readout). No absolute SOTA claim is made. cargo test -p photonlayer-core (23 pass) and -p photonlayer-bench --lib (14 pass) green; clippy clean. Co-Authored-By: claude-flow <ruv@ruv.net> * docs(photonlayer): M3 — fold verified MNIST result + honest positioning + citations into ASSESSMENT Adds the measured real-data MNIST table (optical 74.20% vs full-image baseline 75.40%, -1.20pp, 16x sensor + 16x MAC reduction; +9.25pp learned-vs-random), the verbatim non-overclaiming positioning paragraph (competitive single-layer optical compression, NOT a new accuracy SOTA), the must-avoid language list, and the closest architectural citations (Wirth-Singh arXiv:2406.06534 primary, Bezzam 2206.01429, Lin Science 2018, Li/Ozcan 1906.03417, Wang 2507.17374). Co-Authored-By: claude-flow <ruv@ruv.net> * perf(photonlayer-core): fold Fraunhofer fftshift into checkerboard premult + precompute FFT twiddle tables OPT-A (bit-identical): replace `fft_2d + fftshift_2d` in both Fraunhofer paths (free `fraunhofer()` and `Propagator::propagate_into`) with a ±1 checkerboard premultiply `(-1)^(x+y)` before the transform. By the DFT shift theorem, FFT of the premultiplied input equals fftshift of the FFT, eliminating the fftshift's full-buffer alloc + quadrant copy. True negate (`Complex::ZERO - c`) is exact ±1.0 -> element-for-element identical to the old sequence (new test `checkerboard_premult_equals_fft_then_fftshift`). OPT-B (deliberately changes bits, determinism gain): precompute a per- dimension `TwiddleTable` (`exp(sign·2π·j/n)` for j in 0..n/2) and INDEX it by stride per butterfly instead of accumulating `w *= wlen`. Kills the f32 drift the accumulation injected and recomputes angles once per 2D FFT instead of per row/column. Proven: FFT is bit-for-bit reproducible across runs, and max-abs error vs an f64 reference DFT does NOT increase (it decreases — drift removed). No hardcoded golden hashes/values in the repo to update; re-run-determinism tests stay valid by construction. Measured (release, 64x64 x3000, --ignored --nocapture): fraunhofer OPT-A+B: old(fft+fftshift,accum-twiddle)=210.5ms -> new(checkerboard+table)=116.1ms = 1.81x, max_diff_vs_old=5.7e-6 (f32 noise). M1 cached-propagator benchmark still 2.00x and bit-identical. All 27 photonlayer-core unit tests + propagation bit-identical gate green; photonlayer-ruvector / photonlayer-bench / photonlayer-cli build and tests green. Determinism invariant preserved (scalar cos/sin FFT, no FMA/SIMD/RFFT). Co-Authored-By: claude-flow <ruv@ruv.net> * feat(photonlayer): add Config B (argmax-diff-trained mask) to MNIST bench — isolates the differential lever The M2 benchmark previously reported the differential-vs-plain argmax delta as a small (+0.10pp) transparency footnote, because the single mask was trained for the DECODER objective, not the argmax readout. That understated the Li/Ozcan differential-detection mechanism. This adds a SECOND, clearly-labeled mask trained directly for the argmax-differential objective, so the lever is shown in isolation. Config A is unchanged and remains the product/acceptance headline. Two masks, two objectives — A proves task-useful compression (the product claim); B isolates the differential-detection lever (the mechanism). Both fully deterministic (stated seeds), both reproduced by the integration test. Measured (real MNIST, 4000 train / 2000 blind test, on current core HEAD): CONFIG A (decoder objective, seed 0x6e157) — product/acceptance: full-image baseline (1024 px) 0.7540 optical compressed ( 64 px) 0.7305 (-2.35pp; 16x sensor + 16x MACs) learned vs random decoded +0.0810 (WIN guard, asserted) CONFIG B (argmax-diff objective, seed 0x6e15c) — mechanism, NO decoder: plain argmax I+_k 0.1840 differential argmax I+ - I- 0.3490 differential lever delta +0.1650 (asserted >= +0.05) NOTE: absolute accuracy is single-layer optics-only (no decoder) and modest by construction; the +0.1650 isolates the lever, NOT a headline accuracy. No SOTA/beats language; no cherry-picking — both configs are in the printed table. NOTE on Config A drift: an earlier measurement on commit 69424ecb read optical 0.7420 (-1.20pp, acceptance PASS). The core FFT crate changed underneath us (cbcd0eb2, "precompute FFT twiddle tables") which slightly altered the diffraction output for ALL FFT paths (AngularSpectrum included), shifting Config A to 0.7305 (-2.35pp). Acceptance is REPORTED, not hard-asserted, so the test stays green; the honest current-core number is -2.35pp. Flagged to the core author — the twiddle-table change is not bit-identical to the pre-cbcd0eb2 FFT. Scope: photonlayer-bench only (mnist_bench.rs + integration test). Core untouched. cargo test -p photonlayer-bench --lib (14) + smoke green; full #[ignore] passes (647s); clippy clean. Co-Authored-By: claude-flow <ruv@ruv.net> * test(photonlayer-bench): document the Config-A hill-climb optimizer ceiling Adds run_mnist_config_a (fast Config-A-only harness) and a permanent #[ignore] iteration sweep proving the -2pp acceptance line is NOT a training-budget issue on the drift-corrected (post-cbcd0eb2) FFT core. Measured (seed 0x6e157, 4000 train / 2000 blind test): iters 1500 -> optical 73.05% (-2.35pp) iters 3000 -> optical 73.25% (-2.15pp) iters 4500 -> optical 73.20% (-2.20pp) The block hill-climber has converged; the residual ~2pp gap is an OPTIMIZER limit. Closing it (and reaching ~85-89%) requires analytic gradient descent through the diffraction operator (Propagator::backward_into with conj(H)) — the documented roadmap keystone, not a tonight change. No fabricated numbers; the honest single-mask result is reported, not asserted to PASS. Co-Authored-By: claude-flow <ruv@ruv.net> * docs(photonlayer): M3 — refresh ASSESSMENT to shipped numbers + optimizer-ceiling honesty The pre-OPT-B -1.20pp figure was stale after the twiddle-table FFT change. Updates Config A to the true converged number on the optimized core (73.05% / -2.35pp at 16x/16x; +8.10pp learned-vs-random), adds Config B (+16.50pp differential lever), and states the honest framing: the gap is an optimizer ceiling (sweep: 1500/3000/4500 -> -2.35/-2.15/-2.20pp), closeable only by analytic gradient descent (backward_into with conj(H)) — the roadmap keystone, with ~85-89% headroom. No PASS asserted that the method cannot reach. Co-Authored-By: claude-flow <ruv@ruv.net> * fix(photonlayer-bench): rustfmt + doc_lazy_continuation lint - cargo fmt on all photonlayer crates - Fix doc comment: `+` on continuation line parsed as markdown list marker causing clippy::doc_lazy_continuation. Changed to prose `and`.

The hf-hub API client doesn't follow HuggingFace's 307 redirect to the LFS/CDN host for these files (a plain `curl -L` on the same resolve URL returns 200). Add a redirect-following `curl -L --fail` fallback in download_with_progress(): try hf-hub first, fall back to curl from the HF resolve URL (https://huggingface.co/<id>/resolve/<rev>/<file>), honoring HF_TOKEN. curl is already the download mechanism in hub/download.rs, so this is dependency-free and consistent. Verified: tokenizer_config.json + config.json now download (2.9KB/2.5KB). Note: a SEPARATE pre-existing bug remains — GGUF weights are requested as an unexpanded glob '*<suffix>.gguf' (404), and the GGUF alias points at the safetensors repo; that needs HF file-listing + registry resolution and is out of scope for this redirect fix.

ruvnet	d774f42e72	perf(ruvllm): MLA cache pre-allocation via scatter_set (MlaPrealloc variant) ... Extends the pre-allocated KV cache optimization to MLA attention: - Add KvLayerCache::MlaPrealloc { c_kv, k_rope, seq_len, max_seq } - c_kv: [b, max_seq, kv_lora_rank] - k_rope: [b, max_seq, qk_rope_head_dim] Uses scatter_set along dim 1 (same O(1) per-step append as GqaPrealloc). - MythosCache::with_prealloc now supports both AttnType::Gqa and AttnType::Mla (previously fell back to None for MLA). - reset() handles MlaPrealloc (zero seq_len, reuse buffer) alongside GqaPrealloc.

ruvnet	9d7e0a6aa5	fix(ruvllm): revert pre-repeated KV buffer; wire RDT with_prealloc ... The n_heads pre-repeated buffer (4x larger) was slower for short generations (<~45 decode steps) because the larger allocation cost exceeded the repeat_kv savings. Benchmark confirmed: 65ms vs 62ms (regression). Reverted to kv_heads-sized buffers with repeat_kv still called — scatter_set benefit (O(N²)→O(N) cat bandwidth) remains intact. Also: wire RdtCache::with_prealloc into all RDT generation methods (generate, generate_sampled, generate_stream_sampled), and migrate recurrent_loop + SharedBlock::forward_cached to use RdtKvCache enum (Cat and Prealloc variants matching OpenMythos).

ruvnet	5037f6b31b	perf(ruvllm): eliminate repeat_kv from decode path via pre-repeated KV buffer ... Upgrade GqaPrealloc to store n_heads-wide buffers (pre-repeated KV) instead of kv_heads-wide buffers. This eliminates the repeat_kv() call from the decode hot path: Before (each decode step): cat + repeat_kv([b, kv_heads, N+1, hd]) After: scatter_set(repeat_new_only) + narrow (no repeat of full history) repeat_kv is now called once on the ONE new token (O(kv_heads * head_dim)) instead of on the full growing history (O(n_heads * N * head_dim)). For n_rep=4 (8 Q heads, 2 KV heads) and 100 decode steps: Old repeat_kv cost: sum(1..100) * 4 * head_dim * 4B ≈ 100 MB bandwidth New: 100 steps * head_dim * 4B per new token ≈ 1.6 KB (62000x less) with_prealloc updated to allocate [b, n_heads, max_seq, head_dim]. Benchmark: cpu/mythos_decode_f32 improved 7.4% vs previous measurement. Co-Authored-By: claude-flow <ruv@ruv.net>	2026-06-18 14:26:13 -04:00
ruvnet	3fe772d19c	perf(ruvllm): wire with_prealloc into all generation paths (O(N²)→O(N) KV) ... All three OpenMythos generation methods now use MythosCache::with_prealloc (falling back to MythosCache::new if allocation fails) so the GqaPrealloc scatter_set path is active by default for all autoregressive decode. Affected: generate(), generate_sampled(), generate_stream_sampled(). forward_with_loops() intentionally kept on MythosCache::new (single-pass, no multi-step decode benefit from pre-allocation).

ruvnet	37fe37e5be	perf(ruvllm): KV cache pre-allocation via scatter_set + greedy fast-path ... Two decode-path optimizations: 1. KV cache pre-allocation (O(N²)→O(N) bandwidth across N decode steps) Add KvLayerCache::GqaPrealloc { k, v: Tensor[b,kv_heads,max_seq,head_dim], seq_len, max_seq }. When the cache holds a pre-allocated buffer, append uses Tensor::scatter_set (candle 0.9 in-place op) instead of Tensor:🐱 - Old: cat([past_k, k_cur], dim=2) → new [b,kv,N+1,hd] allocation + full copy - New: scatter_set(k_cur at pos N) → in-place write, O(kv_heads*head_dim) MythosCache::with_prealloc(cfg, b, device, dtype) creates a cache with GQA pre-allocated buffers. reset() resets seq_len (reuses the buffer). 2. Greedy fast-path in generate_sampled / generate_stream_sampled When temperature=0 and no rep penalty, bypass sort_last_dim + topk transfer (320B) and use last_argmax directly (4-byte scalar). Eliminates GPU sort for the common greedy inference case. Co-Authored-By: claude-flow <ruv@ruv.net>	2026-06-18 14:19:47 -04:00
ruvnet	7c6108bb03	feat(ruvllm): add generate_sampled + generate_stream_sampled to RdtModel ...

ruvnet	c7da0b0c46	feat(ruvllm): migrate fused-act kernel to cudarc 0.19 API + CUDA 13 support ... Updates act_kernel.rs from cudarc 0.13 tuple-based launch API to the cudarc 0.19 builder API, and upgrades the direct cudarc dep to 0.19 alongside candle 0.9. API changes: CudaDevice → CudaContext CudaDevice::new() → CudaContext::new() + ctx.default_stream() dev.load_ptx() → ctx.load_module() → Arc<CudaModule> dev.get_func() → module.load_function() → CudaFunction dev.htod_sync_copy / dtoh_sync_copy → stream.clone_htod / clone_dtoh f.launch(cfg, tuple) → stream.launch_builder(&f).arg(&x)...launch(cfg) The module is now stored in FusedActKernel struct (vs global OnceCell loading) since cudarc 0.19 returns Arc<CudaModule> from load_module. fused-act now works natively with CUDA 13.0 — no CUDA_HOME workaround needed.

No more CUDA_HOME=/usr/local/cuda-12.8 workaround required for --features candle,cuda. New capabilities from candle 0.9 (future use): - Tensor::const_set / zero_set / one_set — in-place writes for KV cache - CudaContext::new_stream — explicit stream management - CudaGraph — for CUDA Graph capture (ADR-258 medium-term) fused-act cudarc dep remains at 0.13 (act_kernel.rs uses the 0.13 tuple-based launch API; the two cudarc versions coexist since the staging-buffer path uses its own separate device context).

Applied in both the main loop (remainder weight) and the tail-weight computation. Co-Authored-By: claude-flow <ruv@ruv.net>	2026-06-18 13:57:49 -04:00
