These bind purpose, scope, evidence, coordination, acceptance and stop conditions. No code, experiments, implementation, commits, extraction, deletion or library/index edits. No new source destination allocated; return ungrounded literature leads as leads, not source-backed conclusions. Existing grounded Quotes may support claims; source analysis is not support. Only A turn 1 had source mutation ownership. Choose methods and research judgments within scope; escalate purpose/authority changes, return partial on missing evidence/tools. Validate owned result. Distinguish source claims, documentary observations, conjectures and demonstrations; preserve strongest rival, discriminating evidence, recoverability needs and reason for parked alternatives. Keep learning value distinct from task benefit; do not force compression scores, text shortening or service-first admission. Fresh Explorer B turn 3. Read prior integrations and current coordination, not current A. Challenge the emerging requirement that every worthwhile unknown arrive with named rivals and reachable discriminating evidence. Can bounded inquiry discover its own alternatives without rewarding novelty/noise/promises? Work through a real qualitative inferential claim (generation-confidence-does-not-by-itself-certify-soundness is suggested, not mandatory) to distinguish account change, progress evidence, and next-question selection. What does compression add or fail to add? Compare strongest ordinary explanation-seeking rival; preserve non-event-predictive value. Own only kb/work/open-ended-work-economics/curiosity-exploration/turn-03/explorer-b.md, 1200-1800 words. No new source destinations or experiments.
