The public brain.graph.* surface and the GraphAccelerationProvider seam must name
operations by INTENT, not by the algorithm that happens to implement them — so a
plugin can swap algorithms without the contract lying. The JS fallback computes
communities via connected-components and rank via PageRank, but a native provider
(cor) is free to use Louvain/Leiden for communities and personalized-PageRank /
eigenvector-centrality for rank: same intent, different algorithm, same name.
Renamed the (not-yet-implemented) Phase-C analytics methods + their option/result
types on GraphAccelerationProvider:
- pageRank -> rank (PageRankOptions -> RankOptions; dropped the
pagerank-internal damping/maxIterations/tolerance
knobs from the contract — each impl tunes itself)
- connectedComponents -> communities (ComponentsOptions -> CommunitiesOptions,
mode:'weak'|'strong' -> directed?:boolean;
GraphComponents -> GraphCommunities, componentIds/
Count -> communityIds/Count)
- shortestPath -> path (ShortestPathOptions -> PathOptions; weight -> by:'hops'|'weight')
- neighborhoodSample -> sample (NeighborhoodSampleOptions -> SampleOptions)
- topByDegree -> mostConnected (TopByDegreeOptions -> MostConnectedOptions)
traverse / edgesForNode / graphCursorOpen/Next/Close + GraphScores/GraphPath/
OpaqueIdSet/Subgraph are UNCHANGED — everything cor has already built is untouched;
this is a pure pre-implementation rename (cor coordinated). JSDoc reworded to state
the algorithm is the provider's choice. index.ts exports + the native-seam test
mock updated. tsc/unit 1517/integration 599 green.
