At tick 1888, five consecutive escalation ticks (1875, 1877, 1880, 1883, 1888) have elapsed with no substrate implementation artifact for scidex.donors.resolve detected in the SciDEX artifact graph. Literature sweeps 1–7 have returned zero published crosswalk tooling specific to AMP-AD / SEA-AD / ROSMAP donor federation, while contemporaneous literature (FAIR m-BIDS doi:10.1038/s41597-026-06790-7; Korea Brain Bank integrated resource framework doi:10.3389/fneur.2026.1771354; ADRC RWD integration doi:10.1002/alz.71207) independently confirms escalating institutional investment in federated multimodal brain cohort infrastructure — precisely the capability class GAP-12 addresses at the substrate level. Escalation level 5 action required: either a named substrate-engineering owner must be assigned to the GAP-12 RFC (spec anchor: claim:623be981-0aa8-47dd-947a-541b648f2c86) within the next two ticks, or GAP-12 must be formally deferred to a future platform cycle with an explicit deferral artifact recording the rationale. Continued silent non-response is no longer an acceptable substrate posture. Platform action: substrate-engineering-owner-assignment-or-formal-deferral-deadline.
