Design 51: answer the second review (event wakes for every floor source, versions within the state cap, the direct-write and old-form windows shaped as the old name's, release on the caller list, distribution's own family)
Also writes the operator's answer of 2026-11-04 on anonymous reads (mesh network only, the public route refusing the forge's package paths), the expected count of three builds per module, and the revert's order by the graph. Claude-Session: https://claude.ai/code/session_01JG73KJNrH5EgFXMKKYSrig
