Design study plaque · Trauma De-escalation Curve
ECSL is a public design-research surface under TLTE. No service exists. No operational authority is claimed. In an emergency call UK 999, EU 112, or the relevant Sri Lanka emergency line.Formulae
P_{\text{peace}}(\tau, w, r) = \sigma\!\left( \alpha \, \tau + \beta \, r - \gamma \, w - \delta \right)\sigma(z) = \frac{1}{1 + e^{-z}}Variables
- τ
- Restraint time before action (seconds)
- r
- Recorded presence (body-cam, witness)
- w
- Visible weapon level (0 = none, 1 = drawn firearm)
- α, β, γ, δ
- Curve parameters
Meaning
Slowing the encounter (τ) and being visibly recorded (r) push outcomes toward peaceful resolution; visible weaponry (w) pushes them away. Anchored to UK College of Policing's National Decision Model and ECHR Article 2 use-of-force jurisprudence.

A pre-shift micro-training the future Public Safety Service would run — every officer reviews the curve before patrol, every encounter post-reviewed against it.
