Defines the optional native graph-acceleration provider (cor 3.0) that
brainy feature-detects and routes brain.graph.* / related({node}) /
find({connected}) to, falling back to pure-TS adjacency when absent. This is
the published seam cor wires its native build against (mirrors the existing
VersionedIndexProvider pattern: defined in plugin.ts, exported from index.ts,
implemented externally, feature-detected at runtime).
Contract (locked cross-team in the design thread):
- GraphAccelerationProvider: traverse, edgesForNode, graphCursorOpen/Next/Close,
pageRank, connectedComponents, shortestPath, neighborhoodSample, topByDegree.
Every read op is generation-aware (optional trailing generation?: bigint) so
db.asOf(g).graph.* resolves historically; omitted = now.
- Subgraph: columnar wire format (BigInt64Array node/edge columns, Uint16Array
edgeTypes, optional Uint8Array nodeDepth, truncated flag) — parallel typed
arrays, never array-of-objects; brainy maps u64<->UUID lazily for rendered rows.
- OpaqueIdSet: a find() universe forwarded opaquely into traverse/search for the
zero-crossing query->expand fusion (brainy never inspects it; the provider
version-tags + validates the envelope).
- VectorIndexProvider.search gains allowedIds?: OpaqueIdSet | ReadonlySet<string>
(predicate pushdown — recovers filtered recall lost to post-filtering).
- EntityIdMapperProvider gains entityIntsToUuids(BigInt64Array) — the bigint batch
reverse resolver for Subgraph.nodes; implemented on the JS mapper (TS fallback).
All new public types exported from index.ts. Test: entityIntsToUuids round-trip
+ order-preservation + empty-int sentinel.
