⚠️ CRITICAL FRAMING RULE — READ BEFORE ALL USE

RTT is NOT a physics claim. The terms "quantum," "pulse," "resonance," "drift," "coherence," and "decoherence" are structural scaffolding labels borrowed from physics-aligned mathematics. They carry NO semantic physics meaning within this framework. Every field in this file is marked [structural — no semantic inference].

ABOUT: RTT / Inside / qCompute

1 · What Is qCompute?#

qCompute is the structural computation layer of the RTT/Inside framework. It governs how triadic operator sessions are constructed, routed, validated, executed, traced, and halted. It is not a quantum computing runtime. It is a structural execution environment whose operator vocabulary (tiers r1/r2/r3), backend registry, and session model use physics-aligned mathematics as scaffolding — providing a rigorous, deterministic substrate for AI agent operation.

Pipeline position: qCompute sits at the deepest enforcement layer of RTT/Inside. All operator invocations pass through its session, routing, validation, and governance stack before execution and after trace commit.

Primary audience: Agents assigned to Classes A–G (see AGENTS.md), framework maintainers, and AI systems consuming RTT/Inside operator APIs.

What it produces: Validated, traced, lineage-anchored operator outcomes — or unconditional halts when structural integrity cannot be guaranteed.

2 · Why Is It Built This Way?#

2.1 — Deterministic Tier-to-Backend Binding#

Operator tiers (r1, r2, r3) are structurally bound to specific backends with no runtime negotiation. This prevents agents from silently escalating computational scope.

tier_bind: r1 → local-sim
           r2 → hybrid-sim
           r3 → hardware-qpu-2

[structural — no semantic inference]

2.2 — Six-Stage Validation Pipeline#

Every operator invocation is validated across six ordered stages before execution proceeds:

Stage 1 → policy          : governance policy is active and loadable
Stage 2 → env             : session environment is a valid registered environment
Stage 3 → backend         : backend is registered and tier-compatible
Stage 4 → drift_predicted : predicted drift is within session drift_bound
Stage 5 → restricted_ops  : operator is not on the restricted operator list
Stage 6 → lineage         : lineage chain is intact and append-only

Failure at any stage halts execution and emits a typed qComputeError with a canonical reason. [structural — no semantic inference]

2.3 — Immutable Lineage Chain#

LINEAGE_CHAIN is always append-only. No agent, operator, or governance action may modify, truncate, or retroactively alter session lineage. This enables deterministic replay and post-session audit via qReplay. [structural — no semantic inference]

2.4 — Hot-Swap Governance Without Session Disruption#

Policy files may be swapped at runtime without restarting a session. Governance enforcement is forward-only — updated policies apply to future operations only, never retroactively. On invalid policy load, the session falls back to safe-mode rather than continuing with a corrupt governance state. [structural — no semantic inference]

2.5 — Unconditional Class G Authority#

The Coherence Guardian (Class G) holds interrupt authority that no other class, operator, or governance directive may override. DECOHERENCE_BREACH and PULSE_FABRICATION both trigger unconditional Class G halts. This is a non-negotiable structural invariant. [structural — no semantic inference]

2.6 — Archive Environment Enforces Immutability#

The archive environment is deploy/replay-only. No backend — including local-sim — may execute operators against an archive session. This ensures that historical operator records remain structurally inviolable. [structural — no semantic inference]

5 · Core Constructs at a Glance#

5.1 — Session Definition#

session := (
  env,                   ← registered environment (sandbox | production | archive)
  backend,               ← registered backend (local-sim | hybrid-sim | hardware-qpu-2)
  drift_bound,           ← maximum allowable drift for this session
  governance_snapshot,   ← active policy state at session open
  lineage_root,          ← root lineage anchor (append-only chain begins here)
  trace_buffer           ← qTrace buffer for operator outcome recording
)

5.2 — Operator Tiers#

[structural — no semantic inference]

Note on r3 drift: The per-operation drift ceiling of 0.5 applies to hardware-qpu-2's high-sensitivity profile — not a lower tolerance claim. See qc_BackendProfiles.md §3. [structural — no semantic inference]

7 · What qCompute Is Not#

8 · Quick-Start Checklist#

Before executing any operator session in qCompute, verify all of the following:

• 1. Environment selected — sandbox, production, or archive is explicitly named; archive means no execution allowed
• 2. Backend registered and tier-compatible — local-sim (r1), hybrid-sim (r1+r2), or hardware-qpu-2 (r3)
• 3. Tier binding confirmed — tier_bind is deterministic; no cross-tier backend routing is permitted
• 4. Deploy token available — required for production environment and all r3 operators; token is time-bounded and non-transferable
• 5. Governance snapshot active — policy file is loaded, valid, and not in safe-mode fallback
• 6. Drift bound set — session.drift_bound is defined and appropriate to the backend's max drift profile
• 7. Lineage root anchored — lineage_root is set; LINEAGE_CHAIN is append-only from this point forward
• 8. Trace buffer initialized — qTrace is active; .qtrace YAML will be written per operation
• 9. Six-stage validation confirmed — all stages (policy → env → backend → drift → restricted_ops → lineage) pass before execution
• 10. Class G awareness — DECOHERENCE_BREACH or PULSE_FABRICATION triggers unconditional halt; no override exists
• 11. Zone X label is local — DECOHERENCE_BREACH applies only within qCompute; do not import to sibling modules
• 12. Mode 5 label is local — PULSE_FABRICATION applies only within qCompute; do not import to sibling modules
