Foundation for Track A (GraphRAG on top of existing wiki). Two new packages, both unwired — service behaviour unchanged until commit 2 hooks the pipeline. - internal/graph: pure parser. Extract() walks markdown + frontmatter and emits one Entity + N wikilink Edges per doc. Dedupes per (dst, line), ignores self-references, classifies hall/concept/entity/ source/knowledge from path layout. - internal/graphstore: pgx-backed PGStore mirroring vectorstore's shape. Idempotent Init() creates brain_entities + brain_edges with indexes on src_slug, dst_slug, src_doc, wing, type. Operations: UpsertEntity, ReplaceEdgesForDoc (tx), DeleteByDoc, Neighbors, Subgraph (recursive CTE, depth ≤6), Path (shortest path, depth ≤8). Schema lives on the shared postgres18 instance alongside the brain_embeddings table — no new datastore. See docs/superpowers/specs/2026-05-homelab-training-graph-next-step.md in infra repo + infra#62. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
