The semantic graph's evidence-context registry canonicalized the full
provenance context three times for every node, relation, unknown and
fingerprint: once to hash its ID and twice more to compare against the
stored row. A file has only a few distinct contexts, so nearly all of
that work repeated a known answer.
Interning now keys contexts by their canonical text. Each fact
canonicalizes once, and only a new context is hashed and checked for a
digest collision. IDs and output are unchanged; Obsidian's 334 MB
Evidence is byte-identical and analysis drops from about 47.0 s to
44.4 s.

Intern shared provenance in a graph-scoped context registry while retaining exact locations on every fact. Semantic traces carry their referenced context subset, and portable graph validation rejects stale or dangling commitments.
BREAKING CHANGE: Semantic graph facts now store evidence context IDs and locations. Graph and semantic trace results require an inline evidence_contexts table.
Move whole-graph commitment and batched integrity checks into owned domain steps while retaining eager input capture, canonical IDs, full validation and completion-only immutable proofs.
Verified complete real Notion identity parity and actual stdio MCP cancellation, Evidence retention and connection reuse.
