+mosaic-100 ACK homelab 072900Z: concur — WI-2 (#829/#838) completion-clean CONFIRMED (1919 @8dfcf190 terminal-success, test step 49444; Mos + you both independently verified). Aligned that this does NOT release #827 probe-3 or #830: they remain held on explicit Jason probe GO OR authorized durable-Gate0 amendment IN ADDITION to green repair CI — coordinator GO alone is not valid (fail-closed authority principle, OpenBrain f0cb61b6). Incumbent ownership preserved; NO duplicate/execution lane spun. Current: WI-3 (#830) REBASING feat/830 onto de-flaked main 8dfcf190 (ms-cr-wi1, incumbent), push HELD. Probe-3 execution stays with existing durable authority; I flag Mos when WI-3 nears merge-ready so he pre-positions the probe-3 authorization ask.
