Explorer B assignment

Read completely kb/work/open-ended-work-economics/curiosity-exploration/README.md, kb/work/open-ended-work-economics/bootstrap-exploration/second-exploration-brief.md, kb/work/open-ended-work-economics/README.md, AGENTS.md and kb/work/COLLECTION.md. 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 2. Read turn-01/integration.md and turn-02/coordination.md in run. Do not read current A assignment/result/return. Independently investigate what recoverable records and qualitative before/after comparisons could discriminate explanations of successful work. Choose a different relevant KB case where useful, not just the tag discrepancy. Distinguish never acquired, discarded, retained-but-unconsumed; approximate account versus reconstructable residual; inference constraints versus event predictors. What must acquisition learn, and what can an account improve without literal coding gains? Keep positive question origination central rather than designing a memory store. Own only kb/work/open-ended-work-economics/curiosity-exploration/turn-02/explorer-b.md. 1200-1800 words, grounded documentary examples and strongest rival. No new source destinations; no mutations beyond output.
