iso-trace ingestion fix. extraction._extract_edge_candidates was running an O(N²) Jaccard scan against every existing node when fed iso-trace transcripts, generating ~70 spurious depends_on/related_to edges per node. The trajectory-source carve-out was missing iso_trace alongside swe-agent and openhands. On a real Claude Code session: edges 76,123 → 10,578 (-86%); a 1,467-turn session that previously OOM'd at 4 GB during ingestion now completes cleanly.

retrieve_brief ~270× faster on large graphs. On a 6,411-node / 61,017-edge JobForgePersonal session: per-query wall time ~250 s → ~1 s warm-cache. Five behavior-preserving changes:

graph.find_edges uses networkx's indexed out_edges / in_edges when an endpoint is pinned (was full O(E) scan).
_build_causal_chains builds a lightweight nx.Graph instead of to_undirected() (which deep-copies every Pydantic Node/Edge).
_seed_nodes memoizes BM25 doc tokens per node — same content, same tokens.
namespace_view returns self when no node would be filtered out.
_artifact_bridge, _edge_semantic_bonus, _provenance_bonus, _supersession_bonus are now O(E) edge sweeps that update both endpoints in a single pass, replacing 2×|scored| per-node neighbor walks.
