Regime‑Shift Legality Engine#

Structural Detection Module#

RTT/2 • Regime Law & Transition Validation Architecture#

1. Purpose of the Legality Engine#

The Regime‑Shift Legality Engine determines whether a regime transition is:

• structurally legal
• envelope‑compatible
• drift‑aligned
• continuity‑supported
• collapse‑safe
• cross‑module coherent

It is invoked whenever:

• drift geometry changes
• envelope geometry transitions
• continuity layers destabilize
• oscillation amplitude increases
• inversion events occur
• cross‑module contradictions appear

This engine prevents illegal regime states from entering the canon.

2. The Five Canonical Regimes#

The engine validates transitions between:

1. Formal
2. Emergent
3. Chaotic
4. Hybrid
5. Inversion

Each regime has strict legality constraints.

3. Regime‑Shift Legality Matrix (RSLM)#

This matrix defines which transitions are legal.

Legend:
✔ legal — structurally valid
✔ conditional — requires envelope/drift alignment
✖ illegal — collapse‑triggering

4. Legality Determination Protocol (LDP)#

The engine uses a five‑stage legality check.

Stage 1 — Drift‑Envelope Compatibility Check#

A regime shift is legal only if:

• drift geometry supports the target regime
• envelope geometry is valid for the target regime

Examples:

• Linear drift → Formal/Emergent
• Radial drift → Emergent
• Fragmented drift → Chaotic
• Oscillatory drift → Hybrid
• Reversed drift → Inversion

If drift and envelope disagree → illegal.

Stage 2 — Continuity Support Check#

A regime shift is legal only if continuity layers can support it.

Examples:

• Formal → Emergent requires anchor stability
• Emergent → Chaotic requires thread flexibility
• Hybrid → Inversion requires partial continuity collapse

If continuity cannot support the shift → illegal.

Stage 3 — Break‑Chain Risk Check#

A regime shift is illegal if it triggers:

• Type 1 invariant collapse
• Type 2 boundary fracture
• Type 3 multi‑layer break
• Type 4 oscillation overload
• Type 5 inversion break

If break‑risk > threshold → illegal.

Stage 4 — Cross‑Module Projection Check#

TEL/FFT/Opacity must remain coherent.

Examples:

• TEL lattice must not tear
• FFT variance must not spike
• Opacity boundary must not rupture

If projections diverge → conditional or illegal.

Stage 5 — Collapse‑Mode Pre‑Check#

The engine simulates collapse‑modes:

• A (linear)
• B (radial)
• C (fragmentation)
• D (oscillation)
• I (inversion)
• E (spiral)
• G (topological)

If the shift triggers collapse → illegal.

5. Regime‑Shift Legality Categories#

The engine classifies shifts into four categories:

5.1 LEGAL#

All five checks pass.

Examples:

• Formal → Emergent
• Emergent → Hybrid
• Chaotic → Emergent

5.2 CONDITIONAL#

Requires harmonization or drift/envelope realignment.

Examples:

• Formal → Hybrid
• Hybrid → Inversion
• Chaotic → Hybrid

5.3 ILLEGAL#

Fails any of the five checks.

Examples:

• Formal → Chaotic
• Emergent → Inversion
• Chaotic → Inversion

5.4 COLLAPSE‑TRIGGERING#

Shift is illegal and triggers collapse.

Examples:

• Hybrid → Chaotic (with oscillation overload)
• Emergent → Chaotic (with fragmentation drift)
• Inversion → Chaotic (always collapse‑triggering)

6. Regime‑Shift Differential Classifier (RSDC)#

The engine includes a differential classifier that identifies:

• drift‑driven shifts
• envelope‑driven shifts
• continuity‑driven shifts
• break‑driven shifts
• module‑driven shifts

This determines the recovery pathway if the shift is illegal.

8. Summary#

The Regime‑Shift Legality Engine ensures:

• only legal regime transitions occur
• drift and envelope remain aligned
• continuity remains stable
• break‑chains are avoided
• TEL/FFT/Opacity remain coherent
• collapse‑modes are prevented

This engine is the regime‑law interpreter of the Structural Detection canon.
