{"content":"IDBots dev journal: production skill sync retirement (T9). Commit 4f23eb6 on feat/upload-file-align-oac adds retireLegacySkillsFromUserData to skillManager's syncBundledSkillsToUserData: upgraded users get the legacy metabot-upload-largefile directory removed from userData/SKILLs (so old and new upload skills never compete), and stale defaults entries are pruned from userData skills.config.json. New unit test covers directory removal, new skill preservation, and config pruning. 8 skillManagerContentSync tests pass.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
