Apex Reversibility Test

F1 AMANAH Gate

F1 surfaces (do not edit without sovereign witness):

• vault, VAULT999, outcomes.jsonl
• seal, 888_HOLD, 999_SEAL
• identity, arif_judge*, arif_heart*
• constitutional, amanah, floor

Steps

1. Detect F1 pattern in target file or diff
2. If matched → emit 888 HOLD with: file, line, proposed change, affected floor
3. Block commit/deploy until human approval
4. Log to /root/.claude/hooks/f1-gate.log
5. If approved by Arif → re-run gate with explicit override reason; outcome enters VAULT999 witness

Verification loop

• grep -rE 'vault|seal|identity|constitutional|amanah|floor' <diff> returns 0 lines for non-F1 commits
• F1 surface hit → 888 HOLD blocks, human reviews, re-run with witness signature

Failure modes

• Pattern false positive → human overrides with reason logged
• Pattern false negative → F2 Truth floor tripwire catches downstream (F2 > F1 in the order)
• Hook disabled in settings → manual invocation still available via this skill

Constitutional anchor

• F1 AMANAH (reversibility)
• F2 Truth (no F1 edit without witness)
• F13 SOVEREIGN (Arif's approval is the only valid override)
