learn-cron-builder

Build or repair a source-to-target learning cron for code understanding, subset learning, code-to-code transformation, API/schema/runtime/tool transformation, or human-language translation. Use when a repo needs code-to-human learning notes, strict one-to-one source file plus source-tree output coverage, explicit or fuzzy subset learning, code-to-code transformation, documentation translation, route-policy selection, dual-cursor checklists, master-only acceptance, or cleanup after all learning artifacts are validated.
