Rationale
The directories the durable commands write into are installed rather than created on first use.
Required behaviour
The directories the durable commands write into are installed rather than created on first use.
Failure behaviour
A violation is a WARN finding under the category layout; the command continues and exits as it otherwise would. Under watch it is reported as drift and the command exits 11.
Verification
mj_validate_layout decides it, dispatched from doctor. The behavioural case test/cases/25_continuity_lifecycle.sh proves it, and CI runs that case.
