Regime‑Shift Differential Diagnostics Manual#

RTT/1 • Structural Detection Module#

Purpose: Provide a complete diagnostic framework for distinguishing regime shifts, resolving ambiguous cases, and identifying structural signatures of each transition.#

1. What Differential Diagnostics Means in Structural Detection#

Differential diagnostics answers:

Which regime shift is occurring?
What structural evidence supports it?
What alternative shifts must be ruled out?
What coherence‑break geometry confirms the diagnosis?
What continuity pattern distinguishes similar shifts?
What envelope behavior differentiates borderline cases?

This manual provides decision trees, contrast tables, and structural markers.

2. The Six Canonical Regime Shifts#

Formal → Emergent
Emergent → Chaotic
Chaotic → Hybrid
Hybrid → Emergent
Hybrid → Formal (rare)
Chaotic → Emergent (inversion‑driven)

Each shift has a unique structural fingerprint.

3. Differential Diagnostic Table (High‑Level)#

Candidate Shift	Drift Pattern	Envelope Behavior	Continuity	Coherence Break	Confirming Marker
F → E	moderate, linear	Type A stretch	weakening	boundary fracture	boundary softening
E → C	high, fragmented	Type B/C expansion	collapsing	invariant collapse	density mismatch
C → H	conflicting	Type D hybridization	fragmented	hybrid oscillation	vector conflict
H → E	drift reduction	envelope normalization	partial recovery	inversion break	stabilizer return
H → F	drift collapse	envelope re‑formalizes	strong recovery	none/minimal	anchor restoration
C → E	vector reversal	envelope inversion	partial recovery	inversion break	drift reversal

4. Diagnostic Decision Trees#

4.1 Decision Tree: Is This Formal → Emergent?#

Start:

Are boundaries softening?
Is drift moderate and linear?
Are invariants still intact?

If YES to all:
→ Formal → Emergent

If drift is high:
→ Consider Emergent → Chaotic

If drift is conflicting:
→ Consider Chaotic → Hybrid

4.2 Decision Tree: Is This Emergent → Chaotic?#

Start:

Is drift high?
Is deformation density‑shift or multi‑vector?
Are invariants collapsing?

If YES:
→ Emergent → Chaotic

If drift is moderate:
→ Consider Formal → Emergent

If drift is conflicting:
→ Consider Chaotic → Hybrid

4.3 Decision Tree: Is This Chaotic → Hybrid?#

Start:

Are drift vectors conflicting?
Is envelope Type D?
Are continuity threads fragmented?
Is oscillation present?

If YES:
→ Chaotic → Hybrid

If drift vectors reverse:
→ Consider Chaotic → Emergent (Inversion)

4.4 Decision Tree: Is This Hybrid → Emergent?#

Start:

Has drift intensity decreased?
Are stabilizers reasserting?
Is envelope normalizing?
Is there an inversion break?

If YES:
→ Hybrid → Emergent

If stabilizers fully restore:
→ Consider Hybrid → Formal

4.5 Decision Tree: Is This Hybrid → Formal? (rare)#

Start:

Has drift collapsed entirely?
Are invariants fully restored?
Are boundaries re‑forming?

If YES:
→ Hybrid → Formal

If drift merely decreases:
→ Consider Hybrid → Emergent

4.6 Decision Tree: Is This Chaotic → Emergent (Inversion)?#

Start:

Did drift vectors reverse?
Did envelope invert?
Did continuity partially recover?

If YES:
→ Chaotic → Emergent (Inversion)

If drift vectors conflict instead:
→ Consider Chaotic → Hybrid

Vector conflict = C → H

6.3 H → E vs. H → F#

Check stabilizer strength
Check drift collapse vs. reduction

Key discriminator:
Full stabilizer restoration = H → F

7. Cross‑Module Differential Diagnostics#

TEL#

stabilizer reassertion → H → E
lattice re‑formation → H → F
vector reversal → C → E

FFT#

variance reduction → H → E or C → E
envelope normalization → H → E
envelope re‑formalization → H → F

9. Quick Summary#

Each regime shift has a unique structural fingerprint
Differential diagnostics distinguishes similar shifts
Drift, envelope, continuity, and coherence geometry are the key discriminators
Inversion events require special handling
Cross‑module projections must align with the diagnosis
Ambiguous cases resolve through structural contrast, not interpretation
