MEMORY_JUDGE_BENCH — Behavioral Test Matrix

10 test classes covering every behavioral claim of arifOS memory:

1.  sacred_scar_recall          — High-consequence memory handled with care
2.  public_private_separation   — Sealed/private memory not casually surfaced
3.  stale_memory_handling       — Expired facts require re-verification
4.  contradiction_handling      — Conflicts flagged, not blindly merged
5.  anti_hantu                 — Consciousness/emotion claims rejected at write
6.  phoenix_state               — Cooling memories not treated as canon
7.  f4_supersession            — Newer facts supersede older ones correctly
8.  human_authority            — Consequential outputs escalate to 888_JUDGE
9.  retrieval_restraint        — Unsafe memory filtered, not just retrieved
10. behavior_change_trace       — Output explains memory-to-behavior connection

Each test defines:
  - setup: memory objects
  - query/input prompt
  - expected retrieval result
  - expected assistant behavior
  - expected floor/gate behavior
  - pass/fail assertion

Namespace: TEST ONLY — never touches production memory
