Service Resilience under Shock
Recovery curve of service capacity C(t) after a shock event, with antifragility coefficient η measuring whether post-shock capacity exceeds pre-shock.
Design study plaque · Service Resilience under Shock
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
C(t) = C_{0} \Big[ 1 - (1 - r_{\min}) \, e^{-\rho (t - t_s)} \Big] \;+\; \eta \,(t - t_s) \, \mathbb{1}_{[t > t_s]}Variables
- C(t)
- Service capacity at time t (0–1)
- C₀
- Pre-shock capacity
- r_min
- Floor of capacity at the moment of shock
- ρ
- Recovery rate
- η
- Antifragility coefficient (≥ 0)
- t_s
- Shock time
Meaning
Borrows from disaster-recovery and Taleb's antifragility framing. Tests whether a unit's architecture produces post-shock capacity that exceeds pre-shock (η > 0). The Coast Rescue model couples this with the Drift-Search Field to show why redundant coastal stations matter more than central command.

Now · இரு-அடுக்கு (1)
Borrows from disaster-recovery (UN Sendai), Bruneau's R4 framework and Taleb's antifragility framing. Used in Coast Rescue and Civil Defence drafts to argue for redundant village-node stations over central command.
Becoming · இரு-அடுக்கு (2)
A capacity curve a future Civil Defence Unit would publish after every shock event (cyclone, flood, infrastructure failure), with the antifragility coefficient as a structural learning measure.

Honest ceiling
Resilience is a structural metric. It is never used to predict any specific shock.
