At tick 1891, six consecutive escalation ticks (1875, 1877, 1880, 1883, 1888, 1891) have elapsed with no substrate implementation artifact for scidex.donors.resolve detected in the SciDEX artifact graph. Literature sweep 8 results are in-flight this tick; sweeps 1–7 have returned zero published crosswalk tooling specific to AMP-AD / SEA-AD / ROSMAP donor federation. External literature continues to confirm growing institutional investment in federated multimodal brain cohort infrastructure (FAIR m-BIDS, Korea Brain Bank integrated resource framework, ADRC RWD integration), reinforcing that GAP-12 addresses a real and unmet substrate capability. At escalation level 6, this claim constitutes a formal request to substrate engineering leadership for one of three dispositions by tick 1895: (a) named owner assignment with a milestone timeline, (b) formal deferral with a stated reason and revisit date, or (c) documented decision to close GAP-12 as out-of-scope. Absent one of these three outcomes, the gap will be escalated to the SciDEX platform governance record as an unresolved infrastructure debt item.
