Step-2 PR A: the approval loop end to end with a stub agent, no LLM
and no network.
- transport.py: Transport interface per A1 (send_message,
send_approval_request, ask_question, on_message) with an
InMemoryTransport; no platform SDK outside an implementation
- gates.py: PlanRevision with monotonic rev-N tags; Gate.evaluate
enforces revision binding (stale tags refused with a notice),
operator allowlisting, and approve-word-only semantics; any other
reply is rejection feedback. Channel seam ready for Gitea/Vikunja
approval sources
- control.py: B1 state machine subset with structural gating — the
agent's only actions are SubmitPlan (ends its turn) and AskHuman;
no proceed tool exists. Gate state, revision counters, task_id,
and pending questions checkpoint through StateStore, and boot
resumes an open gate or gates to AWAIT_INPUT, never blind-resumes
- gate.open/approve/reject A9 events complete the log taxonomy
- CLAUDE.md: record the plan-first working convention
- Tests: 15 unit (gates + orchestrator flows), 2 integration
(mid-gate restart with revisions intact; unresolved intents gate
the whole boot)
