The run cap and cadence leave the control reader only inside a Grant with
private fields, so a cap cannot exist without a released brake and an
in-bounds dial. effective() is private; its one caller is read_effective.

Soul s3: the window probe wrote a window-probe-<pid> instance under the real
/etc/gamecult/minds. A leading --root argv flag (argv, because sudo -E carries
the environment) replaces the default root; the probe points the real binary at
a tempdir, whose drop removes whatever a failed assert leaves. No test names
/etc/gamecult any more; the path-derivation test uses CONTROL_ROOT.

Under the binary's umask 077 a first write would have left /etc/gamecult/minds
0700 and unreadable by the units. The attacker reports how much it swept.

Soul s2: under a permissive umask the store was group/world-writable between
CultCache's rename and the chmod, and an fd opened there survived it. The
mind-control binary now sets umask 077 first (the library never touches the
umask). The writer refuses to write through an existing directory, lock or store
that is not root's or is group/world-writable, with the typed UnsafeStore error
naming path, mode and owner. Tests: a non-root open-for-write probe against the
real binary under umask 000; refusals for 0777/0775 directories, 0666/0664
locks and stores, and a non-root-owned directory; accepted root installs.

Modes under umask 000/022/077 via a re-executed test child; a non-root user
(setpriv uid 65534, skipped with a message when not root) cannot write the store
but can read it; an undecodable or NaN dial reads Held(Undecodable) whatever the
brake says, which kills the fail-open default-dial mutant.

Two cargo-mutants survivors from the first run (main -> (), and the
--instance match guard -> true) are killed by a malformed-command table row
and a process-level test of the refused invocation.
