Hand work over with a question still open, and keep it blocking

Situation

A worker opened a question, ran out of session and handed the work over. The next worker starts a fresh task. If the question belonged to the old task, the new task would be acceptable with the question still unanswered, and the handover would have laundered a blocker into a footnote.

What you run

• handover --close: the continuation record, and the task marked handed over
• start <task> --scope <paths>: the follow-up; the prior handover is named
• check: the unresolved question is a failing line on this branch
• question list: the entry, numbered, with the task that opened it
• finish --outcome completed: refused by the same entry

Scenario

setup: finish-blocker-open
given:
  - 'an active task with one unresolved question open against it'
steps:
  - id: hand-over
    run: ['handover', '--close']
    stdin: handover-body.md
    note: 'the record the next session resumes from; --close marks the task handed over so a new one may start'
    expect:
      exit: 0
      stdout_contains: ['\.ai/local/state/handovers/']
  - id: follow-up
    run: ['start', 'the follow-up', '--scope', 'lib']
    note: 'the next task; the prior handover for this worktree and branch is named on the way in'
    expect:
      exit: 0
      stdout_contains: ['^INFO handover', 'same_worktree_same_branch', 'next: majordomus context']
  - id: still-blocked
    run: ['check']
    note: 'the question opened under the previous task still blocks this branch'
    expect:
      exit: 10
      stdout_contains: ['^FAIL blockers', 'unresolved question', 'tabs']
  - id: still-listed
    run: ['question', 'list']
    note: 'the entry, numbered, with the task it was opened under'
    expect:
      exit: 0
      stdout_contains: ['^1  \[unresolved\]', 'tabs']
  - id: refused
    run: ['finish', '--outcome', 'completed', '--verify-command', 'true']
    note: 'completion of the follow-up is refused by the same entry'
    expect:
      exit: 10
      stdout_contains: ['^FAIL blockers']
then:
  - 'the handover carries the branch and head it was written at'
  - 'a question is a fact of the branch, not of the task that happened to open it'
  - 'nothing was resolved by handing over; the next worker sees the same blocker'

Outcome

A blocking question keeps blocking after the work is handed to a new task. The record of who asked and under which task survives, and only an answer clears it.
