HEAD 8 = 117d706df05c75590844b85c891ea40a4df7465c (assembly/v0.69.0 at .worktrees/assembly-294; refs/gate/head8 on kitsubito ~/spt-core-gate-w2 too). Branch your thin lane off it. deployah's question answered as the fix's contract: the reorder moves ONLY the keeper park (pid file + record_shell_launch) ahead of bind(token_b); the viewer still attaches BEFORE bind, while the link is down, so the cell keeps spanning the down-then-relink window it was written for — say that in one line of the commit and keep the assert_eq!(re.attr("changed"), None) that pins "current state, not a replayed edge". Same rule for any sibling you find. SLOTS: the Windows rig (.worktrees/gate-293c, pool label gate-294-*) is mine for ~10 min for the scope commit's docs regen + xtask check, then YOURS — I will send RIG FREE. kitsubito ~/spt-core-gate-w2 is free NOW (detached at 53f63c3a, my 3x rerun finished 3/3 green, claim label gate-294-287b-attach can be taken over); claim it from that worktree under your label.
