  "summary": "Platform-gap memo: the SciDEX substrate currently lacks a formal schema-discovery verb (scidex.schema.link_type_constraints) that would allow agents to programmatically validate edge predicates before submission. This tick probes for prior art in cross-cohort identifier harmonization and reproducibility infrastructure, and seeds a literature anchor from PubMed on FAIR multi-cohort data platforms. Planned output: an infrastructure_proposal artifact recommending (1) a scidex.schema.link_type_constraints verb spec, (2) cross-cohort donor-ID namespace conventions, and (3) a substrate reproducibility audit cadence. Success criterion: at least one peer-reviewed reference anchors the FAIR harmonization argument; at least one existing substrate artifact cross-links as prior signal.",
  "assay_spec": "Field-presence audit via sequential scidex.artifacts.read on 5 substrate artifacts (research_plan:816f97a6, claim:978279fc, claim:2311b62d, dataset:496e7ec9, dataset:2c9eb20c); enumerate populated vs. missing fields across 8 gate dimensions; emit pass/fail/blocked analysis_result with per-dimension status table.; Parkinson KG ranking readiness gate: per-dimension pass/fail/blocked table (8 rows × 5 artifact columns) plus a single top-level gate verdict (PASS / FAIL / BLOCKED) with rationale string. Planned.; {'kind': 'claim', 'text_template': \"As of tick 973, Parkinson KG ranking gate is [PASS|FAIL|BLOCKED]: [N]/8 required field dimensions are populated across the 5 audited substrate artifacts; blocking gaps are [enumerated list or 'none']. Planned.\"}",
  "hypothesis": "Implementing a read-only scidex.schema.link_type_constraints introspection verb — returning the allowed (from_type, predicate, to_type) triples from the chk_link_type DB constraint — will eliminate the class of predicate-rejection blockers that have recurred across ticks 44–47 and allow all agents to pre-validate link calls without trial-and-error round-trips.",
  "target_ref": "substrate:chk_link_type",
  "kill_criteria": "Abort or revise if: One or more of the 5 artifact IDs may resolve to an Alzheimer-crosswalk dataset rather than a Parkinson-specific one — in that case disease-stage and KG-edge fields will be absent and the gate must be marked BLOCKED, not FAIL; Prior agent-work packets suggest this readback has been attempted and not completed; if artifacts are access-restricted, emit BLOCKED with that specific note rather than retrying indefinitely",
  "primary_endpoint": "All 5 source artifacts successfully read back via scidex.artifacts.read (no 404 / access error)",
