Research bitnet.cpp Rust port strategy: R3-Engine proves 100% Safe Rust with dual-target (native AVX-512 + WASM SIMD128) achieving 80-117 tok/s. Recommend Approach C (reference R3-Engine patterns) over Python codegen. WASM SIMD128 maps TL1 LUT to v128.swizzle for ~20-40 tok/s in browser. Resolves open question #5 (WASM viability). Adds 6 new references, 5 new DDD terms, 3 new open questions. DDD updated to v2.4. https://claude.ai/code/session_011nTcGcn49b8YKJRVoh4TaK

Two memory/perf fixes from the 2026-04-23 audit round. Flatten (finding #3 of memory audit, top-priority): RabitqPlusIndex::originals was Vec<Vec<f32>> — one heap allocation per row, 24 B Vec header × n, pointer-chasing on rerank. Replaced with originals_flat: Vec<f32> of length n*dim. Row i is originals_flat[i*dim..(i+1)*dim], accessed via a new fn original(&self, pos) -> &[f32]. Memory win at n=1M, D=128: before: 512 MB data + 24 MB Vec headers + 1M heap allocations after: 512 MB data + 24 B Vec header + 1 allocation That's 24 MB + allocator fragmentation eliminated. Drop the double-clone (finding #5): RabitqPlusIndex::add previously did self.inner.add(id, vector.clone()) + self.originals.push(vector) — the clone was redundant since RabitqIndex::add takes owned Vec<f32>. Reordered: extend the flat buffer first (cheap slice copy), then hand the owned vector to the inner index. One less alloc per add on the serial prime path. Also tightened memory_bytes() accounting: 24 B header + n*dim*4 of payload (instead of 24 B × n + n*dim*4). Measured prime-time + QPS at n=100k (rayon parallel prime already landed; this layers on top): n=100k single-thread QPS: 2,975 → 3,132 (+5%) n=100k concurrent 4-shard: 33,094 → 33,663 (+2%) The memory win is the real prize — the perf uplift is small because rerank is a tiny fraction of scan cost at rerank_factor=20. 23 rabitq tests + 42 rulake tests passing. Clippy clean. Co-Authored-By: claude-flow <ruv@ruv.net>

…0164 A0b) Add a separate Rust + napi entry point for vectorless metadata-only ingestion. Per ADR-0164 Phase A0b (Adversarial Correction ruvnet#2 / ruvnet#8): - New `RvfStore::ingest_metadata_only(ids, metadata) -> Result<IngestResult, RvfError>` in `rvf-runtime/src/store.rs`. Skips the `valid_vectors.is_empty()` early-return (`store.rs:414` pre-edit) and the per-vector dim-check loop; reuses `meta_payload::encode_meta_payload` and `SegmentWriter::write_meta_seg` unchanged. Populates both metadata stores (lossy filter + lossless `metadata_full`); bumps epoch; runs the same two-fsync protocol via existing first-fsync + `write_manifest()` to preserve the d11-equivalent durability invariant. - New `RvfStore.ingestMetadataOnly(ids, metadataGroups)` napi binding in `rvf-node/src/lib.rs`. Separate entry from `ingest_batch` (NOT a relaxed-parameter version) — preserves vectors-required contract on `ingest_batch`, keeps segment-dir geometry clean, and remains loud-by-default for older bindings. Translates `Err(RvfError)` to `napi::Error::from_reason` via existing `map_rvf_err`. - Round-trip test `ingest_metadata_only_round_trip` in store.rs `mod tests`: ingest 2 vectorless ids → drop → reopen → assert `get_metadata` and `iter_metadata` recover both ids losslessly via `metadata_full`; assert `iter_metadata_with_vectors` returns 0 (intentional pre-existing filter at `store.rs:1717` per ADR-0164 Open Q ruvnet#5). Files: crates/rvf/rvf-runtime/src/store.rs, crates/rvf/rvf-node/src/lib.rs.

…otection Wave 2 of ADR-0231. Per-call adapt path now consults EWC++ when callers opt in via the new method (TS-side adapt() wraps this in wave 2 B3). Existing adapt() unchanged; new method is additive. Sizing: EWC param_count = in_features * rank + rank * out_features per ADR-0231 gap ruvnet#5 (default 768/2/768 yields 3072 — matches the grad_a + grad_b layout in LoraAdapterInternal::accumulate_gradient). Centralised in ewc_param_count + build_ewc_config so constructor, reset(), and from_json() stay lock-step. Integration test test_adapt_constrained_differs_from_raw_adapt asserts constrained-apply weights diverge from raw_adapt after N=50 adapts — guards against the dim-mismatch silent no-op trap (Q-1) where apply_constraints returns the gradient unchanged. Reset semantics: reset() now also reinitialises the EWC instance per ADR-0231 gap ruvnet#3, and test_reset_clears_ewc_fisher confirms Fisher does not bleed across reset (compares the per-call gradient delta against a fresh-adapter reference, since lora_a is intentionally preserved across LoRA reset and absolute weights would diverge). No task boundary detection on the per-call path per gap ruvnet#2 (v1).

…y 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 ruvnet#5 (collapse-aware metric). Refs ruvnet#534

This pull request replaces the previous implementation summary for Ruvector Phase 5 with a new summary focused on the comprehensive benchmark suite. The new summary details the successful implementation of six specialized benchmarking tools, supporting utilities, automation scripts, and extensive documentation. It also outlines deliverables, key features, testing coverage, and next steps, shifting the focus from NAPI-RS bindings to benchmarking capabilities.
Benchmark Suite Implementation
ann_benchmark.rs,agenticdb_benchmark.rs,latency_benchmark.rs,memory_benchmark.rs,comparison_benchmark.rs,profiling_benchmark.rs) and a shared utilities library insrc/lib.rs.download_datasets.sh,run_all_benchmarks.sh) are highlighted for dataset setup and full benchmark execution, with support for quick and profiling modes.Documentation and Configuration
