## 4) Sensor Dashboard (Minimal, Computable)
### 4.1 Node sensors (all Z nodes)

text id=”sgp7″
SENSORS.SGP.NODE.MIN:
ρ := L/C
R := Ġ/Ḋ
TTC
T_repair
B := buffers (reserves/redundancy/time slack)
κ := effective coupling (from bind weights + dependency density)
σ, σ_cap, ρσ
p95_variance (where applicable)
CI (CityOS optional)
P_state

### 4.2 Lane sensors (Z3 lane nodes)

text id=”sgp8″
SENSORS.SGP.LANE.Z3:
for lane ∈ {ENRG,HLTH,SAFE,TRANS,FOOD,HOUS,EDU}:
ρ_lane := L_lane / C_lane
R_lane := Ġ_lane / Ḋ_lane
TTC_lane
V_p95_lane
κ_lane := f(bind weights among lane nodes)
CI := concentration index (optional): reliance on few critical nodes/routes

			
---
## 5) Threshold Pack (Inline)

text id=”sgp9″
THRESHOLDS.SGP.DEFAULT:
TH_ρ1: ρ > 1.00 => overload begins THρ_2: ρ > 1.30 => runaway / P3 risk

TH_R_1: R < 1.00 => slow attrition begins
TH_R_2: R < 0.80 => fast attrition / M3 risk

TH_FENCE: TTC ≤ T_repair => FenceOS must truncate now

TH_SIGMA: ρσ > 1.0 => operator shear (policy/initiative churn > absorption)
TH_KAPPA: κ > κ* => cascade amplification risk

VAR_GATE: p95 variance > V* => escalate repair plan
TH_CI: CI > CI* => brittleness risk; diversify lanes/routes

## 6) ERCO Loop (SGP City Control Tower)

text id=”sgp10″
ERCO.SGP.CITY.LOOP:
cadence:
Z0/Z1: weekly
Z2: weekly/biweekly
Z3 lanes: weekly + after-shock within 48h
Z4: weekly ops + quarterly strategy

1) READ: all Node + Lane sensors
2) COMPUTE: ρ, R, TTC, κ, ρσ, V_p95, CI
3) PHASE_EVAL per node -> P_state
4) If TH_FENCE OR (multi-lane ρ_lane>1.30 AND κ_lane high):
FenceOS.TRUNCATE (σ clamp + κ dampening + stop accelerators)
5) ROUTE_REPAIR:
prioritize actions that:
(a) extend TTC fastest
(b) restore R≥1
(c) reduce ρ below 1
6) PROTECT/REBUILD buffers B (post-stitch mandatory)
7) STITCH corridors gradually (only after 2-cycle retest)
8) RETEST: confirm p50 + p95 improvements

## 7) City-Specific Collapse Trace (Mechanism-first, anonymised)
### TRACE.COLLAPSE.SGP.A — “Energy stress → multi-lane cascade via κ”

text id=”sgp11″
TRACE.COLLAPSE.SGP.A:
Step 1 (Z3 Lane ENRG):
ρ_lane(ENRG) > 1.0 and TTC_lane(ENRG) short

Step 2 (κ_lane coupling):
ENRG → HLTH (E_dep, w=0.60): HLTH capacity constrained -> Ḋ_lane(HLTH)↑ -> R_lane(HLTH)<1 ENRG → TRANS (E_dep, w=0.45): TRANS reliability drops -> FOOD logistics strain

Step 3 (lane aggregation to CityOS):
Lane nodes push load into NODE_SGP_SGP_Z3_CITYOS:
ρ(Z3)↑, κ↑, V_p95↑, buffers B(Z3) start depleting

Step 4 (Z2 institutional backlog):
via E_load (Z2→Z3) feedback:
ρ(Z2)>1, R(Z2)<1 (backlogs grow), TTC(Z2) shrinks

Step 5 (Z1 households):
increased time/cost/logistics variance -> buffers Time/Money ↓
ρ(Z1) rises; p95 conflict/schedule variance breaches -> further variance to Z2

Step 6 (Z4 governance load + σ risk):
crisis load rises -> pressure to inject changes σ
if ρσ(Z4)>1 -> operator shear -> Ḋ rises -> R falls -> reinforces overload loop

Collapse mode:
– if abrupt service KO: M1
– if R<1 persists: M2 – if multi-lane ρ>1.3 + κ high: M3

## 8) City-Specific Repair Trace (FenceOS truncate + ERCO stitch + buffer rebuild)
### TRACE.REPAIR.SGP.A — “Clamp σ, dampen κ, restore R≥1”

text id=”sgp12″
TRACE.REPAIR.SGP.A:
Trigger:
TTC_lane(ENRG) ≤ T_repair_lane(ENRG)
OR (ρ_lane>1.30 in ≥2 lanes AND κ_lane high)

Action 1 (Z4 GovernanceOS via ERCO):
FreezeWindow (Operator protection):
– clamp σ (pause non-core policy/process churn)
– reduce coordination load (simplify execution)
Policy routing:
– push E_policy + E_repair to CityOS/Institutions (w~0.45..0.40)

Action 2 (Z3 CityERCO):
FenceOS.TRUNCATE:
– stop accelerators that increase κ or drain buffers
– temporary decouple critical binds (κ dampening on lane graph)
ERCO.ROUTE_REPAIR:
– allocate to bottleneck lane raising Ġ fastest (restore R_lane≥1)
– protect buffers B(Z3) (reserves + redundancy routes)

Action 3 (Z2 InstitutionERCO):
Variance compression:
– attack p95 backlog/gaps first
Freeze churn:
– no new internal process changes while ρ>1
Raise R:
– increase Ġ throughput OR reduce Ḋ backlog inflow

Action 4 (Z1 FamilyERCO + Z0 IndividualERCO):
– protect TimeBuffer + MoneyBuffer
– reduce schedule coupling κ (simplify)
– truncate optional commitments (σ clamp at household)
– stitch stable routine corridor (sleep → meals → stable blocks)

Exit condition (must hold 2 cycles):
For key nodes/lanes:
ρ ≤ 1.0 AND R ≥ 1.0 AND TTC > T_repair
Plus:
buffers trend positive AND p95 variance improving

## 9) Minimal “SGP City Insert Block”

text id=”sgp13″
SGP.CITYERCO.INSERT.MIN:
Singapore CityOS runs ERCO+RECL across Z0–Z4 and core lanes (ENRG/HLTH/SAFE/TRANS/FOOD/HOUS/EDU).
It monitors ρ, R, TTC, κ, ρσ, p95 variance (and CI optional).
When TTC ≤ T_repair or multi-lane ρ>1.3 with κ high:
FenceOS truncates accelerators (σ clamp, κ dampening) and ERCO routes repair to restore R≥1 and rebuild buffers.
