leased-path
An advisory: it explains, and blocks nothing, on a write into paths a running lease owns, by a caller that names no lease.
What it catches
A write into paths a running lease owns, by a caller that names no lease.
Why
The writer is either that lease, not saying so, or a second agent about to collide with it; magus cannot tell which, so it advises rather than refuses. It speaks once per session per lease. Every write used to repeat it: 8,419 servings in one audit, 52% of every advisory the guard served, for a fact the writer had after the first.
Seeing it
A verdict names its rule in brackets, which is how you got here:
advise [leased-path]: ...
magus describe rule leased-path prints the same entry at a terminal, and
magus describe rules lists every rule this workspace enforces.
