RTT‑Inside / Python — Semantic Operator Hooks

Purpose#

Define the semantic‑level operator grammar for Python‑class systems. These operators sit between raw execution signals and the base RTT chain, providing:

  • AST + object‑graph semantic form extraction
  • invariant evaluation
  • drift detection
  • semantic stability scoring
  • routing of unstable forms into the Resonance Chamber
  • ROA oversight for semantic evolution

This file is non‑substrate‑exposing, operator‑first, and canon‑aligned with RTT/1 and RTT/2.


1. Semantic Form Operators#

PY_FORM_SCAN — AST + Object Graph Scan#

PY_FORM_SCAN(ast_node, object_graph) → semantic_form

Extracts a stable semantic representation from Python execution.


PY_FORM_NORMALIZE — Canonical Form Normalization#

PY_FORM_NORMALIZE(semantic_form) → normalized_form

Ensures forms are comparable across executions.


PY_FORM_COMPARE — Semantic Delta#

PY_FORM_COMPARE(form_a, form_b) → semantic_delta

Used for drift detection and invariant evaluation.


2. Invariant Evaluation Operators#

PY_INVARIANT_CHECK — Stability Evaluation#

PY_INVARIANT_CHECK(semantic_form, evidence) → {stable, unstable}

INVARIANT_REGISTRY_I2 — Accept / Sandbox / Reject#

INVARIANT_REGISTRY_I2(candidate, evidence) → {accepted, sandboxed, rejected}

Shared with Internet2; prevents premature canonization of unstable invariants.


3. Drift Detection Operators#

PY_DRIFT_DETECT — Runtime Divergence#

PY_DRIFT_DETECT(runtime_state, expected_state) → drift_signal

PY_DRIFT_CLASSIFY — Drift Severity#

PY_DRIFT_CLASSIFY(drift_signal, semantic_delta) → {minor, moderate, severe}

PY_DRIFT_BOUND — Drift Containment#

PY_DRIFT_BOUND(severity, form) → bounded_form

4. Semantic Health Operators#

PY_SEMANTIC_HEALTH — Stability Score#

PY_SEMANTIC_HEALTH(forms[], drift_signals[]) → health_score

PY_SEMANTIC_PROFILE — Execution Profile#

PY_SEMANTIC_PROFILE(runtime_events) → semantic_profile

5. Resonance Chamber Routing (Tier‑2 Sandbox)#

ROUTE_TO_RESONANCE_CHAMBER#

ROUTE_TO_RESONANCE_CHAMBER(form, tier_class) → chamber_path

SANDBOX_BOUNDARY_ENFORCE#

SANDBOX_BOUNDARY_ENFORCE(chamber_state) → allowed_egress

6. ROA Compatibility (Internet3 Seed)#

ROA_OBSERVE#

ROA_OBSERVE(forms, drift, invariants) → observation_state

ROA_DIAGNOSE#

ROA_DIAGNOSE(observation_state, semantic_health) → diagnosis

ROA_DECIDE#

ROA_DECIDE(diagnosis, policy) → action_class

ROA_ACT#

ROA_ACT(action_class, execution_flow) → routed_state

7. Semantic‑Level Chain (Python Inside)#

PY_FORM_SCAN
→ PY_FORM_NORMALIZE
→ PY_INVARIANT_CHECK
→ PY_DRIFT_DETECT
→ PY_DRIFT_CLASSIFY
→ PY_DRIFT_BOUND
→ PY_SEMANTIC_HEALTH
→ (Resonance Chamber if unstable)
→ (ROA oversight)
→ RTT_PY (via base chain)
