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 A turn 3. Read prior turn integrations and current coordination. Question: how originate/select across reachable explanatory contrast, unexplained success with missing records, and valuable unfamiliar direction, without mere novelty/fluent future promises? Develop a practical candidate-generation and selection account using at least two concrete KB opportunities; tag verification is one candidate, not mandatory winner. Specify bounded exploratory investment that can make vague unknowns assessable without requiring full rivals/tests at admission. Keep comparison qualitative, account for purpose/resources/authority, retain strongest alternative and false-negative risks. Do not run experiments or design controller/store. Do not read current B. Own only kb/work/open-ended-work-economics/curiosity-exploration/turn-03/explorer-a.md, 1200-1800 words.
