The mental model has principle-distiller extract each spec's Modification Grammar at spec completion, but the agent register says it serves only disembark, distilling a packed lifeboat

A premise contradiction (severity minor) found by the cross-document consistency pass.

• End A: .abcd/development/brief/01-product/03-mental-model.md:93 — "extracted by principle-distiller at spec completion into typed memory pages"
• End B: .abcd/development/brief/04-surfaces/README.md:421 — "Distils durable principles from a packed lifeboat's decision record"

The mental model says each spec's Modification Grammar section is extracted by principle-distiller at spec completion into typed memory pages, which is how the Modification axis is closed. The surfaces index's agent register says principle-distiller serves disembark alone and distils durable principles from a packed lifeboat's decision record. The register's Serves column names the verb that builds the agent's input, so nothing at spec close builds its input. The agent cannot both run only on a packed lifeboat and run at every spec's completion.
