+M4-001 remains blocked. Second repair froze as synthetic tree e076bc65 with exact connector.kind parity and full Mosaic 1002-test/package gates green, but fresh immutable review REQUEST CHANGES for one missing symmetric direct regression: tmux+matrix rejection branch lacks coverage. Same sole owner is adding only that red-first test. PR #788 remains unchanged at b7eb724c; RoR and pipeline 1848 remain red; root-test source verdict remains unknown due ENOSPC. No commit/push/merge, M4-002, parent closure, or live action.
