The identity equation. Σ(E) is the synthesis of what is — evidence, weighted. Δ is the intentional nudge you add, or the impulse you resist. C is the constancy that holds them in coherent relation across time. Three terms. Irreducible. Less than three doesn’t hold.

Evidence · the equation, made operational

Σ(E), made operational. Signal quality climbs 20 → 60 → 95% as emotion is weighted into the synthesis; the four pillars are the regulator, built.

The constancy term given a palette — trust, patience, curiosity, confidence as a therapeutic colour language with real CSS tokens.
How it has been tended
First sketch of I = C(Σ(E) ± Δ).
drift: Might be too tidy to be true.
Reconciled the notation with belief-over-equals so they read as one object.
Settled on three irreducible terms; resisted adding a fourth.
drift: Is C really separable from Σ, or am I double-counting?
