nisse-dev now runs only the conversational loop. The gated state machine
it was built alongside is gone:
- Removed control.py, planner.py, executor.py, approvals.py, gates.py
(command_form moves to loop/reader.py), publish.py and poller.py, the
old assembly in agent.py (its shared helpers move to loop/build.py),
the store's state-machine view (get_state, transition), their tests,
the old end-to-end and live planning/milestone/gate tests, and
specs/orchestrator.qnt with its scenarios.
- Roles are driver, helper, expert and classifier; driver is required.
loop:, roles.planner, roles.executor and tuning.executor are refused
with what to use instead; tuning.driver takes the turn cap and failure
limit.
- The benchmark and the capability matrix measure the driver: the
loop's own system prompt and tools, the task's plan as the agreed
restatement. Task plans end with finish_milestone, so earlier runs
show as (old); stored runs' executor tuning reads as the driver's.
- A delegation on the loop records what its helper's alias resolved to
(L9), as the old path's did.
- The dump shows a work item's revision and what it waits for.
- Behaviour the old tests covered and the loop shares stays covered:
driver runs that fail on a model call, stop mid-turn, reset the
failure count; go-aheads ignoring case and punctuation; a request too
big to fit is never sent; the assembly tests, now on build_loop_agent.

test_loop_properties.py walks the new loop with a seeded mix of operator
and Gitea actions (go-aheads, stale go-aheads, answers, comments, merges,
the comment-then-merge race, closes, abandon, a crash and restart) and an
adaptive scripted model, checking every loop.qnt property after every
step. It found two bugs, both fixed with regression tests: abandoning an
item left its open PR open (the model's fix 1, now in code), and after a
review fix became a follow-up PR, the next fix went to the merged branch.

A Quint model of the design in docs/Architecture.md (PR #90): intake,
restatements and go-aheads, park-and-switch, blocked dependencies,
harness-owned milestones, waiting for merges, review follow-ups, record
issues, crashes and build VM wipes. It found five gaps; the model carries
the proposed fixes, and loop_scenarios.qnt keeps each counterexample.

specs/orchestrator.qnt models control.py: states, gate, pending
questions, comment cursors, publish intents and the worker queue, with
operator messages, Gitea comments, work outcomes (exceptions included)
and a crash at any point interleaving freely. Eight properties.
Seven counterexamples, each written out as a trace in
specs/orchestrator_scenarios.qnt and reproduced against the real code in
nisse-dev/tests/test_quint_counterexamples.py (xfail, strict, until
fixed):
1-4 an approval or feedback lands on a plan the operator had not seen:
a double 'approve', 'approve rev-1' meant for the architecture,
approving on both channels, and 'approve' plus an afterthought;
5 a crash after the PR opens but before PR_OPEN publishes again and
cannot get back to PR_OPEN;
6 a crash while answering a review comment loses it silently;
7 'project complete' leaves the plan issue open.
no_stranding, await_input_has_a_question and execution_needs_approval
held over 200,000 random traces of 40 steps, and under Apalache's
exhaustive check to depth 8, which does find counterexample 1 at that
depth. No behaviour changes here.
