fix(applier): never silently re-enable a disabled tag ruleset - #1030
Conversation
The tag canon's identity rule is `target == "tag"` AND
`conditions.ref_name.include == ["~ALL"]`. That is correct, and the
header explains at length why `name` must play no part in it. But the
rule also does not look at `enforcement` -- so a ruleset somebody
deliberately switched OFF still matches it, and the canon body carries
`"enforcement": "active"`.
The consequence: the next scheduled run PUTs that body and the ruleset
is live again. Nothing reports it. The only trace is a new version in
`rulesets/{id}/history`, which nobody reads. The applier's own report
says `REPAIRED`.
This is not hypothetical. 375 branch rulesets across this estate were
disabled on purpose on 2026-09-22. An applier with this shape on the
tag side would undo the equivalent decision invisibly.
Repairing the SHAPE of a disabled ruleset is defensible; flipping the
ENFORCEMENT field is an owner decision. So a non-active match is now
reported as DISABLED-NOT-REVIVED and skipped, and `--revive-disabled`
exists for when that really is what was meant. Default off.
Test property 13 is a detector, not a grep for a flag name: it requires
the guard to sit BEFORE the PUT, to `continue` out, and to default to
off -- so moving it after the write, or making it fall through, still
goes red. Its mutant strips the guard and the detector must refuse.
⚠ My first mutant deleted 3 lines of a 4-line guard and left a dangling
`fi`; the suite correctly reported that its red measured bash's parser
rather than the control. Fixed to 4. Suite: 29/29.

Check all matching rulesets before duplicate reconciliation.
With --apply --reconcile-duplicates and REVIVE_DISABLED=0, the duplicate branch bypasses the disabled-ruleset guard. It can delete a disabled zero-bypass ruleset, or retain a disabled ruleset with bypass actors and PUT CANON_PUT to it. CANON_PUT sets enforcement to active.
Check every matching ruleset before reconciliation. If any enforcement value is not active, report DISABLED-NOT-REVIVED, set rc=2, and skip the repository unless REVIVE_DISABLED=1.

Verify the required disabled-ruleset report.
disabled_guard_holds does not check for DISABLED-NOT-REVIVED. An applier can skip the PUT and pass this property without reporting the disabled ruleset. Check that the guarded branch emits DISABLED-NOT-REVIVED before it executes continue.

The defect
scripts/apply-tag-ruleset-canon.shidentifies a live tag ruleset astarget == "tag"ANDconditions.ref_name.include == ["~ALL"]. That is right,and the header explains at length why
namemust play no part in it.But the identity rule also does not look at
enforcement— so a rulesetsomebody deliberately switched off still matches, and the canon body carries
"enforcement": "active".The next scheduled run PUTs that body and the ruleset is live again. Nothing
reports it. The applier's own line reads
REPAIRED. The only trace is a newversion in
rulesets/{id}/history, which nobody reads.This is not hypothetical. 375 branch rulesets across this estate were
disabled on purpose on 2026-09-22 at the owner's instruction. An applier with
this shape on the tag side would undo the equivalent decision invisibly.
Note the asymmetry that made it easy to miss: the sibling branch applier
(
apply-branch-gates.sh) filters on.enforcement=="active"when it selects.This one only consults
enforcementwhen deciding whether a match is alreadyCONVERGED— after which a disabled ruleset falls straight through to the write.The cure
Repairing the shape of a disabled ruleset is defensible. Flipping the
enforcement field is an owner decision. So:
DISABLED-NOT-REVIVEDand is skipped;--revive-disabledexists for when that really is the intent, default off.No other behaviour changes. A ruleset that is already active is handled exactly
as before.
The test
Property 13 is a detector, not a grep for a flag name. It requires the guard
to sit before the PUT, to
continueout of the arm, and to default to off — somoving it after the write, or letting it fall through, still goes red. Its mutant
strips the guard and the detector must refuse.
⚠ Worth recording: my first mutant deleted 3 lines of a 4-line guard and left a
dangling
fi. The suite correctly reported that its red measured bash's parserrather than the control, which is the only reason I noticed. Fixed to 4.
Suite: 29/29, mutant killed. No ruleset was written by this work.
