Auditable public records

Evidence ledger

• ev-sc10-household-scopefirst-party observation: SC10 observations are reported for one identified household and are not population prevalence evidence.
• ev-sc10-methodfirst-party observation: Published methodology and source records explain what was observed, sourced, inferred, and left unresolved.
• ev-sc10-28-day-audittelemetry result: A sanitized audit covers 28 consecutive days in one three-cat household: 428 entries, 261 eliminated visits, 299 cleaning starts, and 26 recorded drawer cycles.
• ev-sc10-jam-incidentincident analysis: One physical drum jam lasted about 34 hours while the device reported standby, raised no fault code, and generated roughly 20 visit-like events without visible cats.
• ev-sc10-fault-episodestelemetry result: The audit distinguishes 15 native fault state-transition events from approximately eight independent E1-family fault episodes.
• ev-sc10-drawer-cohorttelemetry result: Twelve substantive drawer fills had a median of 21 cleaning cycles, but early empties, reinsertion signals, and jam recovery prevent treating that median as universal capacity.
• ev-sc10-travel-scopefirst-party observation: The owner was absent for approximately two weeks with scheduled sitter support; the SC10 was not treated as an unattended appliance.
