The seat's bodies hold TakeInTaken (branch, source, entries with repository and pull) and TakeInPending (branch); revision's answer gains none-yet and its revision is optional; meshcatalogclient reads the field, never the error's words. The holders' and readers' uses of the answer follow (a pointer revision). Builds: design 47 G §476, §493, §530, §454, §648 Claude-Session: https://claude.ai/code/session_01JG73KEq4zoDfM9WtYpcQgZ
