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.
Remove forwarding wrappers and shadow aliases, migrate callers and verification scripts to their owners, and share one exhaustive semantic resource-bound projection.
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.
