The bind-mount logic goes to hosts_mount.sh, the Magisk-module and
cache-invalidation logic to hosts_magisk.sh. Both flat siblings, both in
both deploy lists; the two lists were then checked to correspond exactly
in both directions, since a push with no matching cp stages a file that
never lands and the enforcer would fail to source it.
Audited for stdin-draining `while read` loops BEFORE extracting, because
piping one would change behaviour in a way stubs cannot catch. There are
none here. Also confirmed no function writes a global, so there was no
cross-half hazard of the kind that kept NET_BUILT in curfew_enforcer.sh.
69 assertions, 43/43 and 62/62 lines, 17 mutations all killed. Two survived
the first run and both were real findings:
- the unmount give-up threshold was not pinned. Raising it from 5 to 500
changed nothing observable, so the enforcer could have spun 500 times
per poll against a mount that was never going to clear. Now asserted as
a call count.
- the `[ ! -f $HOSTS_TARGET ] && return 1` guard in
is_bind_mounted_correctly is PROVABLY EQUIVALENT: sha256_of returns
empty for a missing file, so the existing -n check already rejects that
case. No test can distinguish it. Equivalent code is a claim of a check
that is not being made, so it is deleted rather than covered by a test
that would pass either way. Old and new bodies were compared across all
four input states -- both-missing, target-missing, match, mismatch --
and agree on every one.
That deletion is the only non-verbatim function; the other 19 moved
untouched, making this the first fully verbatim extraction of the session.
Ordering is asserted where it is load-bearing: /system must go back to ro
after rw, and +i must be restored after being dropped. Presence assertions
alone would pass with either pair reversed.
UNVERIFIED ON DEVICE -- the highest-stakes of the four enforcer splits now
outstanding, since a failure to source leaves nothing blocking while the
phone looks normal. Over-cap count 20 -> 19.
