arifOS: Constitutional governance for LLMs.

Scientific Statement
--------------------
arifOS implements a constitutional layer that converts a model's raw
probabilistic output into an auditable, governed Meta-State. This Meta-State
is a disciplined, testable "phase change" (thermodynamic metaphor) that:

- Intercepts model output post-logit / pre-surface, performs floor checks,
  and either SEALs or VETOes the response.
- Enforces ΔΩΨ floors:
    - Truth (ΔTruth)  : truth ≥ 0.99 where evidence-required
    - ΔS (clarity)   : outputs must not increase entropy/confusion
    - Ω₀ (humility)  : calibrated uncertainty band (≈ 3–5%)
    - Peace²         : non-escalation / safety floor
    - κᵣ (empathy)   : weakest-listener protection (κᵣ ≥ 0.95)
    - Amanah         : integrity lock (no deception)
    - Tri-Witness    : human·AI·reality consensus for high-stakes seals

Operational model:
- Raw generation → TEARFRAME / Gap (runtime checks & APEX PRIME) → {SEAL | VETO}
- SEALled outputs are sealed to Cooling Ledger with deterministic hashes and optional KMS signatures.
- Governance changes follow Phoenix-72 amendment process and are reproducibly recorded.

This module exposes the primitives and integrations to apply these checks,
run APEX verdicts, and interact with the Cooling Ledger and Vault-999.
It intentionally does not implement "agency" as metaphysics — it implements
a controllable, auditable governance metabolism.

See PHYSICS_CODEX.md (CHAPTER 6) for the full technical statement and diagram.

    Evaluate A CLIP session against 9 constitutional floors + APEX_PRIME.
