Cite the cat-mode rule by quote, not line number, and test the quote exists

[EdbertChan]

Summary

A checker quotes a house rule when it blocks a reply: a hedge is a reason to verify, never a place to stop.

The problem: the notices cited that rule by line number, and the number was wrong. Line numbers also go stale at once.

The fix: the notices now quote the rule itself. Two new checks confirm the quote exists in the rule file and that no checker cites a line number.

Review Claim

Checker notices cite the house rule by its words, and the words are checked against the real rule file.

Review Lane

Review Unit

engine-runtime

Safety Invariant

Each change only affects when a checker warns about or blocks a reply. Checkers never edit files or run commands, and each change adds tests that fail before and pass after.

Slice Rationale

This slice comes last: it only fixes how the rule is cited. It touches the same checker as the earlier slices but changes no trigger or release logic, so it stands alone.

Non-goals

• Does not change when the checker warns or blocks.
• Does not edit the rule file itself.
• Does not touch the other checkers.

Measured

Command: source scripts/test/hermetic_env.sh; python3 engine/hooks/unverified-tag-ledger/tests/test_hooks.py with this commit's tests and the parent's checker code (base) versus this commit's checker code (head).

• base: unverified-tag-ledger: Ran 61 tests, FAILED (failures=1)
• head: unverified-tag-ledger: Ran 61 tests, OK

Test Plan

Test Plan

• source scripts/test/hermetic_env.sh; python3 engine/hooks/unverified-tag-ledger/tests/test_hooks.py -> Ran 61 tests, OK
• python3 scripts/ci/check_hook_test_coverage.py engine/hooks/unverified-tag-ledger -> check_hook_test_coverage: OK (1 hook(s) checked)
• New cases: the quoted phrase exists in the rule file (stays silent), and a cited line number would be reported (fires).

Revert Plan

Revert Plan

• Safe to revert? Yes
• Revert command: git revert <merge commit of this PR>
• Post-revert steps: None
• Data migration? No

Note

Low Risk
Copy and test-only changes to rule citations; block/reminder logic and triggers are untouched.

Overview
unverified-tag-ledger block/reminder copy no longer cites cat-mode/SKILL.md:269. User-facing strings and module docs now point at cat-mode/SKILL.md and embed the rule text ("a hedge is a trigger to verify, never a place to stop") so citations stay correct when the skill file moves.

Tests were updated to assert on that phrase instead of a line number. Two guards were added: the phrase must appear in corpus/skills/cat-mode/SKILL.md, and hook .py/.md sources must not contain SKILL.md:<digits> again.

No change to when the hook blocks, logs tags, or injects reminders—only how the house rule is quoted.
