D62 — M9 closed with two items unbuilt

Decision

M9 is closed with two items unbuilt (negotiated fallback for escapes, escape templates) and its gate not met

Alternatives

Build both

Reason

The flow planner the fallback belongs to measured below the simple corridors and is off; planning takes 0.1–2 s, so a template cache saves nothing (doc 05 §23)
