The Three Collapse Modes: Amplitude, Slow Attrition, and Fast Attrition (War)

Not all collapses look the same, but they all obey the same Phase physics. Every collapse is simply a different way the system crosses the Phase Fracture Point (PFP) of the Phase Survivability Band (PSB).

There are exactly three mechanical collapse modes.

Mode I — Amplitude Collapse (KO)

What it is

A large instantaneous deletion of regenerative mass.

What it looks like

  • sudden disasters
  • mass death events
  • nuclear-scale shocks
  • total system blackout
  • catastrophic infrastructure loss

Phase physics

Loss rate jumps far above Human Regeneration Bandwidth (HR-BW) instantly.
Collapse is immediate.

Mode II — Slow Attrition Collapse

What it is

A gradual failure where loss rate slowly but persistently exceeds regeneration.

What it looks like

  • falling fertility
  • operator thinning
  • chronic staff shortages
  • decaying maintenance
  • institutional hollowing
  • rising error rates

Phase physics

The system quietly drifts below regeneration viability (AHD + HR-BW erosion) until it crosses PFP.

This is the most dangerous collapse mode because it looks stable until the snap.

Mode III — Fast Attrition / War Collapse

What it is

Rapid deletion under high coupling and violence.

What it looks like

  • wars
  • civil wars
  • insurgencies
  • genocides
  • multi-year mass casualties
  • political implosions

Phase physics

Loss rate violently exceeds HR-BW while coordination channels are damaged.
Replacement cannot keep up. Fracture cascades.

Why this classification matters

Old collapse theories mix “causes” (climate, war, economy).
Phase physics shows those are Arrow Forcing Terms (AFT) — not collapse types.

Collapse type is defined by rate dominance:

  • how fast mass is being deleted
  • versus how fast it can regenerate

That is the true classification.

The control objective

Civilisation OS exists to:

  • prevent Mode II hollowing (early warning + stitching)
  • prevent Mode III war cascades (early truncation)
  • and ensure Mode I never crosses regeneration margins

The takeaway

Collapse is not mysterious.
It is a rate-inequality law:

Collapse occurs when loss/destruction rate exceeds regeneration/replacement rate.

Everything else is surface narrative.
