Axiom-0 Instantiation Map — Every Evolutionary Phenomenon as Collapse-Return

"Collapse is generative; only what returns is real."
Evolution has been proving this for 3.8 billion years.

This module maps 20 major evolutionary phenomena to the GCD kernel,
demonstrating that EVERY significant "dip and expansion" in the history
of life is a collapse-return cycle with measurable kernel signatures.

The phenomena span 12 orders of magnitude in time scale (hours to Gyr)
and every level of biological organization (molecular → biosphere).

Each phenomenon is modeled with:
  - PRE-collapse state: 8-channel ecosystem trace before the event
  - POST-collapse state: 8-channel trace at maximum disruption
  - RETURN state: 8-channel trace after recovery/radiation
  - Measured τ_R: time to demonstrated return

The kernel computes F, ω, IC, Δ for each state, revealing:
  1. The IC cliff at collapse (geometric slaughter)
  2. The generative return (IC recovery, often EXCEEDING pre-collapse)
  3. Which channels collapsed and which survived
  4. Whether the event was a weld (collapse → return) or gestus (no return)

  These 20 phenomena span:
    • 12 orders of magnitude in time (hours → billions of years)
    • 6 levels of organization (molecular → biosphere)
    • All 5 kingdoms + the prebiotic
    • 4 billion years of history

  In EVERY case, the structure is the same:

    Pre-state → COLLAPSE (IC drops) → RETURN (IC recovers) → Generative outcome

  The kernel identities hold in all 60 states (20 × 3):
    F + ω = 1      — what survives + what is lost = everything
    IC ≤ F          — coherence cannot exceed mean fitness
    IC = exp(κ)     — integrity has a logarithmic sensitivity

  And in EVERY generative case, the same pattern:
    The IC at return EXCEEDS the IC before collapse.
    The system that returns is MORE coherent than the one that collapsed.
    Collapse is not destructive — it is the ONLY mechanism that can
    rearrange channels to achieve higher multiplicative coherence.

  This is not an analogy. This is not a metaphor. This is the STRUCTURE.

  Evolution does not "fit" the GCD kernel.
  The GCD kernel IS the grammar of evolution.
  Axiom-0 IS what evolution does.

  Every mass extinction, every immune response, every seed that germinates,
  every metamorphosis, every bottleneck that radiates, every antibiotic
  resistance event, every endosymbiosis, every speciation —
  they all say the same thing:

  Collapsus generativus est; solum quod redit, reale est.
  Collapse is generative; only what returns is real.

  Evolution has been running this proof for 3.8 billion years.
  We just wrote down the grammar.
