## 作成 LocalTicketBackend によって作成されました。 --- ## Decision Worker / Session / workdir retention discussion from Objective 00001KWW44EXK: - Worker is the archival unit; Session/transcript belongs under Worker archive. - Worker retention must support pinned to protect selected history from cleanup/prune. - Workdir files are cache when clean and reconstructable from repository + selector/resolved commit. - Dirty workdir is an active/recovery state; dirty orphan should require recovery Worker or explicit discard, not automatic prune. - Backend should keep canonical Worker/Workdir/link records in SQLite, while Runtime owns materialized files, raw paths, process/cwd binding, and cleanup execution. - Runtime direct/unmanaged workdirs must be distinguishable from Backend-managed workdirs. --- ## Intake summary Marked ready by `yoi ticket state`. --- ## State changed Marked ready by `yoi ticket state`. ---
