The memory substrate has session_memory pages distilled via dev-sync memory; the board chapter says no dev-sync verb ships and no dev-sync code exists.

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

• End A: .abcd/development/brief/05-internals/07-memory.md:50 — "distilled by the internal/core/memory adapter via dev-sync memory"
• End B: .abcd/development/brief/04-surfaces/08-abcd.md:583 — "no dev-sync verb is on any shipped surface, and no dev-sync code exists in the tree."

07-memory's source-class enum has session_memory pages 'distilled by the internal/core/memory adapter via dev-sync memory', re-distilled on each sync, and names the vendor memory directory as a harvest source for dev-sync memory. 08-abcd states that no dev-sync verb is on any shipped surface and no dev-sync code exists in the tree. A page class produced only through a verb that does not exist cannot be described as working, so one of the two pages is wrong about the tree.
