Replace a 250ms sleep in the work-line test with a real control

[leaf-agent]

test_local_work_chrome_does_not_take_its_holder_gesture asserted an absence — no action in the log after clicking the work line — behind page.wait_for_timeout(250) and with no control. tests/CLAUDE.md names both halves of that: a wait consumes a fact the system states, and "an absence is also what a page that never had the behaviour produces, so a test asserting one names a control that must first produce the presence: the same gesture where it is supposed to work."

The fix keeps the forbidden gesture, then presses a neighbouring option as that control and lets its send settle through round_trip. One outbox in gesture order means a pick the work line had taken would already stand ahead of it, so the whole log is read once and compared exactly — no budget, and the verdict now rests on a product fact.

Bug-back, both directions

The reading this guards is the .lf-work-line entry in worksInside (leaf.js:842).

The new test still catches the real defect. Dropping ".lf-work-line" from that selector list makes the work line cast its holder's pick, and the new assertion fails on it:

At index 0 diff: ('jobs', {'options': ['job-mounts']}) != ('jobs', {'options': ['job-heater']})

The old test went green over a dead gesture. With lf-options' click handler disabled outright — no option pickable anywhere on the page — the old form passed (1 passed), because nothing was left that could have written an action. The new form fails there, as a test with a control should: the control is not met.

Worth being precise about what was not wrong: on this machine the 250 ms budget was not itself load-bearing. With the work-line defect injected, the old test failed even at wait_for_timeout(0) — the POST goes out inside the click and the server is in-process. The sleep is a convention violation and a standing hazard rather than the thing that hid a bug; the missing control is what made the test vacuous.

Verification

• uv run pytest tests/test_render_options.py -q --run-nightly — 46 passed
• uv run pytest tests -q — 549 passed, 6 skipped
• ruff format --diff / ruff check — clean

The control is the right shape and the bug-back in the description checks out — #answer() is reachable only from this.#done.onclick (lf-options.js:242), so the group sends nothing but the one choose in this flow, and jobs being choose multiple keeps the #job-mounts chosen assertion load-bearing rather than letting the heater pick clear it.

One narrowing came along with the rewrite that the fix doesn't need — noted inline.
