The guard chapter describes agents abcd starts through its claude runner, but the implement chapter counts agents against the ceiling on the premise that abcd runs no agent

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

• End A: .abcd/development/brief/04-surfaces/17-guard.md:385 — "An agent abcd starts through its claude runner has no terminal, so nobody can"
• End B: .abcd/development/brief/04-surfaces/27-implement.md:129 — "abcd runs no agent, so the count it holds"

17-guard describes 'an agent abcd starts through its claude runner', launched with the lane's base commit. 27-implement holds a session's agent ceiling only against the session's own agent_start lines 'because abcd runs no agent'. If abcd starts agents itself, that premise is false, and agents abcd launches can sit outside the count the ceiling is held against.
