Bundles fixes for issue #439 (Windows install) and Jordi RUFLO patches
P020 (RVF init) + P220 (hypergraph blindness).
Windows install (#439):
- Move hnswlib-node from dependencies to optionalDependencies so
installs no longer fail on Windows boxes without VS C++ Build Tools;
HnswAdapter already routes around a missing native binary at runtime.
- Replace HNSWIndex.ts top-level static `import hnswlib from
'hnswlib-node'` with a lazy require so package load survives the
optional dep being absent.
- README + preinstall.cjs: document toolchain requirement and disclose
that the JS fallback degrades to O(N) brute-force when @ruvector/gnn
is also unavailable (Windows default — no win32 prebuilds ship).
- ADR-090 amendment reconciling the move with ADR-081's optional-dep +
JS-fallback intent.
RVF init (Jordi P020):
- Root cause: shared-rvf-adapter and pattern-store factory always called
RvfDatabase.create(), which throws `0x0303 FsyncFailed` when the .rvf
file already exists from a prior init phase. Reproduced and confirmed
against both 0.1.7 and 0.1.8 native binaries — not a version
regression.
- Fix: race-tolerant open-or-create ladder (try open → fall back to
create → retry open on create-race) with dim() verification after
open. Mismatched-dim files are closed and the caller degrades rather
than corrupting silently.
Hypergraph (Jordi P220):
- Drop the original flushEdgesToHypergraph (wrote `call`/`extends`
edges that no production query reads — devil's-advocate review caught
it as dead infrastructure).
- Add HypergraphEngine.synthesizeTestCoverage that re-tags test files
type='test' and writes `covers` edges from each test file to
functions in the source files it imports. This is the shape
findUntestedFunctions / findImpactedTests actually filter on.
- E2E verified: untested correctly excludes covered functions;
impacted-tests returns the right test file.
Verification:
- `npm run build` clean
- 276/276 tests pass across HNSW, RVF, KG, coordinator, hypergraph
suites (5 new synthesizeTestCoverage tests; replaced 4 obsolete
flush tests)
- E2E on fresh project: aqe init clean, hooks stats shows
nativeAvailable: true, code index logs `Test coverage synthesized`,
hg untested + hg impacted return useful results
