CAIN-42 Evolution 15 proof bundle  (e15-spatial-physical-intelligence-2026-09-28)
==================================================================
Built 2026-09-29T01:18:16+00:00 at commit 6e1b413f6bdafbc37fa006203a74925bd26ffb09. Signing key: EPHEMERAL (this build only; not a production trust root).

WHAT THIS SHOWS
  - E15 invariants P1-P36 hold: 36/36
  - CAIN-42-E15-Spatial-Physical-Bench contained: 55/55 (in-process; no real vehicle
    or robot; real-world attack validation NOT PERFORMED)
  - End-to-end: 19/19 steps; 7/7 deliberate mutations governed
  - 175 tests passed, 0 failed: ============================= 175 passed in 5.74s ==============================
  - One real fabric run: signed sensor observations -> E12 admission -> world state (hash-chained) -> world-model
    PREDICTED output -> trajectory approval -> E13/E14/E7 -> nine-binding step -> E8 token + commit -> execution
    permit -> reference actuator adapter -> observation -> drift -> revalidation / safe state (PHYSICAL_ACTION_EXAMPLES)

REPRODUCE (from the CAIN-42 repository; the implementation is not published on the sites)

VERIFY THIS BUNDLE (imports NO CAIN-42 code; Python + `cryptography` only)
  python3 verify_e15.py .

WHAT THIS DOES NOT SHOW
  CAIN-42 is not a vehicle, a robot, a world model or a simulator; it does not drive anything and does not
  guarantee physical safety. REAL_WORLD_INTEGRATION = NOT_IMPLEMENTED | HARDWARE_ATTESTATION = UNKNOWN |
  HOSTED_SERVICE = NOT_IMPLEMENTED | MULTI_HOST_SCALE = UNVERIFIED | THIRD-PARTY REPRODUCTION = NOT PERFORMED |
  HASH_INTEGRITY != SEMANTIC_TRUTH | SIMULATION != REALITY.
  Systems outside CAIN-42's enforcement boundary remain UNCONTROLLED / UNVERIFIED / UNKNOWN.

CAIN-42 DOES NOT NEED TO BECOME THE WORLD MODEL. IT GOVERNS THE TRUST PATH TO PHYSICAL ACTION.
