A background child runs in a worktree, and without --repo the order
verbs derive identity from the git toplevel's basename - the worktree's
name, not the repo's. Measured in the session that built the form: the
claim ran before the worktree and won; coord-order-done ran inside it and
exited 1 "no claimed order ... for dispatch-bg-form", leaving the order in
flight until --repo repo-mailbox was passed. The order's own starter
template carried the same defect.
§19b gains two checks (red against 24adf59, same predicate), the
template passes --repo <repo> to claim and done, and the skill says why.
Suites under bash 3.2: coord 257, board 495, route 73, orders 116,
guard 54 = 995. npm test 12/12.
Order 20260923T070445Z-9974217048-from-.claude (follow-up to 24adf59).
