Spectral coherence optimizations (50ms → 5ms for 500 vertices):
- Reduce Fiedler outer iterations from 50 to 8
- Reduce inner CG iterations from 100 to 15
- Reduce effective resistance samples from 50 to 3
- Reduce resistance CG iterations from 100 to 10
- Reduce power iteration for largest eigenvalue from 50 to 10
Canonical min-cut optimizations:
- Replace O(n) Vec::contains with O(1) HashSet lookups in partition membership
- Build partition_sets once, reuse across all vertex signature computation
- Use HashMap<u16,usize> for O(1) cactus vertex lookup instead of linear scan
- Track active count explicitly instead of recounting each phase
- Use std::mem::take to avoid clone during merge
New benchmark tests for all 4 cognitive stack modules:
- canonical_bench: CactusGraph 30v = ~1ms native (ArenaCactus 64v = 3µs WASM)
- spectral_bench: SCS 500v = ~5ms (10x improvement from 50ms)
- container_bench: 100 ticks = 9µs avg (target: <200µs)
- canonical_witness_bench: 64v witness = 3µs (target: <50µs)

Add canonical, spectral, cold-tier, and canonical-witness feature flags
across ruvector-mincut, ruvector-coherence, ruvector-gnn, and
cognitum-gate-kernel. Create ruvector-cognitive-container crate skeleton.
Implementation agents are building the full modules in parallel.

The pgrx test steps used --no-default-features without passing the pg17
feature, causing linker failures against PostgreSQL symbols. Also escape
bracket notation in doc comments to prevent unresolved intra-doc link
errors.

- ruvector-postgres: Add EdgeType import in mincut tests, remove
incorrect Some() wrapping on pgrx default!() test params
- ruvllm: Make ane_ops module available on all platforms (not just macOS)
so tests can reference it unconditionally; fix unused variable warnings
- sona: Add explicit lifetime annotations on RwLockReadGuard/WriteGuard
to fix clippy mismatched_lifetime_syntaxes errors
Co-Authored-By: claude-flow <ruv@ruv.net>
- Add #[allow(unreachable_code)] for NEON fallback in distance/mod.rs (ARM
always returns before the Scalar fallback, causing clippy error on macOS)
- Restructure standalone Dockerfile to use workspace layout so dependency
crates with workspace inheritance (edition.workspace, version.workspace)
can resolve correctly during Docker builds

- Run cargo fmt --all to fix formatting in 362 files across the entire workspace
- Add PGDG repository for PostgreSQL 17 in CI test-all-features and benchmark jobs
- Add missing rvf dependency crates to standalone Dockerfile for domain-expansion
- Add sona-learning and domain-expansion features to standalone Dockerfile build
- Create npu.rs stub for ruvector-sparse-inference (fixes rustfmt resolution error)

Implement trait-based IntelligenceProvider extension point for external
quality signals. Addresses PR #190 proposal (renumbered from ADR-029 to
avoid collision with existing ADR-029-rvf-canonical-format).
- IntelligenceProvider trait with load_signals() and quality_weights()
- FileSignalProvider built-in for JSON file-based signal exchange
- IntelligenceLoader for multi-provider registration and aggregation
- QualitySignal, QualityFactors, ProviderQualityWeights types
- calibration_bias() on TaskComplexityAnalyzer for router feedback
- 12 unit tests (all passing)

rvlite's writer_lease.rs used __errno_location (Linux libc) under a
generic #[cfg(unix)] guard, causing link failures on macOS where the
equivalent is __error. Split the extern and wrapper into separate
#[cfg(target_os)] blocks matching the pattern already used in
rvf-runtime/src/locking.rs.

Resolve conflicts in hnsw_am.rs:
- Keep metric_from_index() (PR Fix#3) AND dimension extraction from atttypmod (main)
- Use atttypmod dimensions to initialize meta.dimensions instead of 0
- Combine sorted result comments from both branches

- Remove KahanAccumulator from forward_push hot paths, use plain Vec<f64>
(halves working set from 16 to 8 bytes/element for cache efficiency)
- Standardize near-zero thresholds in bmssp.rs: replace hardcoded 1e-30
with NEAR_ZERO_F64 = 1e-15 constant matching other solver modules
- Add f64→f32 overflow checks in neumann.rs and true_solver.rs
SolverEngine::solve() before downcasting matrix/rhs values
- Add cfg-gated rayon parallelism for random walks in random_walk.rs

All 171 tests pass. Downstream crates (wasm, node) compile clean.

Six bugs fixed in the HNSW access method:
1. SIGSEGV on repeated queries: beginscan must allocate xs_orderbyvals
and xs_orderbynulls arrays (like GiST/SP-GiST do). Without this,
the executor writes distance values to stale palloc memory, causing
segfaults on the second+ query in the same backend.
2. Empty HNSW graph: connect_node_to_neighbors was a no-op TODO stub.
Implemented bidirectional connections (new→neighbors, neighbor→new)
with pruning at M/M0 capacity limits.
3. Wrong distance metric: hnsw_build hardcoded DistanceMetric::Euclidean
regardless of the operator class used (e.g. ruvector_cosine_ops).
Added metric_from_index() to read the metric from the opclass
support function via index_getprocid + get_func_name.
4. Wrong result ordering: BinaryHeap::into_iter().take(k) returns k
arbitrary items, not the k closest. Removed .take(k) before sort.
5. xs_recheckorderby must be false: setting it to true triggers PG17's
IndexNextWithReorder distance comparison, which errors on harmless
floating-point differences between index-stored and heap vectors.
6. Use-after-free in endscan: added null check and null-out of
scan->opaque to prevent double-free across rescans.
Also applied the same xs_orderbyvals fix to ivfflat_ambeginscan.

Three additional hardening fixes for the SPARQL subsystem, building on
PR #172:
1. Parser: replace hardcoded saturating_sub(6) with saved_pos variable.
The old backtrack assumed all update keywords are 6 chars, but LOAD,
DROP, and CLEAR are 4-5 chars, causing incorrect parse positions.
2. Executor: change default_graph from Option<&'a str> to Option<String>
and remove Box::leak calls in the GraphPattern::Graph handler. Each
GRAPH clause previously leaked a String allocation that was never freed.
3. Operators: wrap ruvector_sparql parse/execute/format in catch_unwind
so that panics from non-empty but malformed queries are converted to
PostgreSQL ERROR messages instead of crashing the backend.
Closes#167
