Realism Checks
6 of 7 realism checks pass; 1 disclosed WARN.
No implausible residential bills
Tier A hard invariant
PASS — 0 residential Billing rows outside a plausible amount range
Household-linked meter coverage
Disclosed sanity band 10–95% of households
PASS — 15.35% coverage, within the disclosed band
Outage duration ceiling
Reliability plausibility check
PASS — 0 outages exceeded 30 days
Substation peak load vs. design capacity
Disclosed realism watch-item, not a hard fail
WARN — 68 substations observed above 150% of design capacity
Billing occurs only after meter install
Chronology invariant; fixed and remediated this release
PASS — 0 bills dated before their meter's install date
Frequency readings are physically plausible
Statistical plausibility across the full billing history
PASS — 0 physically-implausible frequency readings
Formal housing connects at a higher rate than informal housing
Directional realism check, not an exact-value target
PASS — formal 14.42% vs informal 7.17%, directionally correct
