Purpose#

Coherence Drift describes how and why coherence weakens within a framework.
It identifies the forces that pull a framework away from stability, resonance, or field‑locking.

Coherence drift is the primary cause of:

coherence collapse
paradox amplification
harmonic instability
regime regression
dimensional collapse

This module defines the drift vectors and diagnostics used by the Coherence Analyzer.

Drift Model#

1. Harmonic Drift#

Loss of harmonic structure due to:

inconsistent operator firing
unstable resonance patterns
harmonic noise

Harmonic drift prevents C2 → C3 transitions.

2. Paradox‑Induced Drift#

Coherence degradation caused by:

paradox overload
paradox vectors
paradox density spikes

This drift often precedes collapse.

3. Operator‑Driven Drift#

Occurs when operator families are:

imbalanced
suppressed
conflicting
overloaded

Examples:

missing B‑Ops → boundary drift
overloaded T‑Ops → cascade drift

4. Dimensional‑Driven Drift#

Coherence loss caused by dimensional instability:

D3 → D2 collapse
D4 → D3 regression
dimensional boundary stress

Dimensional drift often produces paradox vectors.

5. Collapse Drift#

The most severe form of drift.
Triggered by:

paradox overload
operator collapse
dimensional collapse
regime instability

Collapse drift leads to C1 → C0 regression.

Drift Vectors#

A drift vector describes direction + magnitude of coherence loss.

Components:#

source (operator, paradox, dimensional, regime)
direction (e.g., C2 → C1)
magnitude (low / moderate / high)
trigger (specific cause)
risk (collapse likelihood)

Example:

vector: C2 → C1
source: paradox overload
magnitude: moderate
trigger: unresolved paradox boundary
risk: collapse possible

Collapse Dynamics#

Collapse occurs when drift exceeds stability thresholds.

Collapse triggers:#

paradox density > paradox capacity
harmonic instability > resonance threshold
operator imbalance > coherence tolerance
dimensional collapse > coherence boundary

Collapse outcomes:#

C2 → C1 (harmonic collapse)
C1 → C0 (full coherence collapse)
regime regression
dimensional regression

Drift Diagnostics#

Inputs:#

coherence envelope
harmonic stability
paradox load
operator balance
dimensional envelope
regime state

Outputs:#

drift category
drift vector
drift magnitude
collapse risk
drift signature

Example (Abbreviated)#

Framework: Narrative Analysis Model
Drift:
  category: D2 (Dimensional Drift)
  vector: C1 → C0 (risk)
  magnitude: moderate
  collapse_risk: moderate
  trigger: dimensional collapse (D3→D2)
notes: paradox exposure and operator inconsistency weaken coherence
