The ledger reports two things, and keeps them apart on purpose: how fast a signal becomes a cited, dispatchable memo, and whether the intervention worked. The first is measured today; the second is a mechanism that accrues evidence as real interventions occur.
Signal → attribution → cited memo → dispatch route is a single automated batch. The manual baseline — correlating a satellite signal to a served notice across agencies — is documented in weeks (CAG, 2024). That is the reduction: weeks → one automated run, no human correlation step.
Intervention effectiveness requires a real intervention between the frozen counterfactual and a realized outcome. Nobody has acted on these yet, so we do not claim an impact number — attributing natural change to ourselves would be dishonest. 0/0 actions actioned so far.
