New: prefix()/CLI forward three keys for a sibling binding and four for an
explicit root; create records the sibling on the row, omits it from the
pane's --env and still pins it in the injected publish commands; the
issue's scene (a pane with WORKSPACE_ROOT and MAM_JOBS_DIR only) moves its
audit log with --registry-dir and leaves the control root alone;
worktree_prepare's pane --env carries no DELEGATE_JOB_LOGS_DIR.
The three existing four-key forwarding assertions (user-approved) compare
FORWARDED_ENV = CP_ENV[:3]; CP_ENV and the negative assertions are kept.

`ps -o lstart=` pads a one-digit day ("Oct 1"); loop_lock.sh's mam_lstart
squeezes the spaces before comparing, but A8 wrote the raw value, so the
live holder's marker looked stale and the second loop was not refused on
the 1st-9th of every month. The test now normalises like the product (the
product is unchanged) and also runs with a `ps` shim that always prints a
padded lstart, so the padded case is checked on every date.
The other tests that record a live lstart (test_o3_scoped_guard
_get_lstart) already normalise; test_o2's markers carry fixed stale values.
