Cross-cutting concepts that shape the whole system:

  • Track A vs Track B

  • trust propagation

  • shared handover

  • note governance and cognition scoring

  • scanner pipeline stages and bounded scanner IDs

  • MCP policy and mutation boundaries

  • contract versioning

Trust remains asymmetric across the system:

  • source tree: trusted

  • notes: conditional

  • agent output: untrusted until verified

  • bundle: trusted

This page recaps only the local boundary. Use Cross-cutting Concepts when you need the full canonical model.

These concepts appear across the proof path, the MCP surface, and the cognition layer, so they are better treated as shared vocabulary than page-local detail.
