Subject: [PATCH] test(#2056): cover accept-branch (real foreign-prefixed dir)
 + no-project_code edge
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds the guard's positive leg (a real MEM-01-* dir resolves under its own
prefix) and pins the strict default (no project_code → any prefixed query
is foreign → not found). Covers the accept/reject/own-code matrix.
