Explicit completion (bb stelow done). Done-ness was inferred from audit + idle. The worker commits; the host verifies in code (build only at audit, research/explore only with a passing verify and no pending question). Every refusal names the fix.
Host-served playbook (bb stelow playbook). Exact state, transitions, and stage-playbook paths per card — no more skill list | awk discovery pipelines. Missing files fail loud.
Fixed
Preset fence.preset add/remove/assign refuse card workers; preset list stays open.
Prompt completion clause.DONE_PROTOCOL is a single-source const referenced by all five card spawn paths, pinned by the prompt-contract test.
