# run-h3.sh — operator harness for the #484-H3 Agent-Teams hook-seam test.
#
# This script does NOT spawn claude. It ensures the fixture exists and prints
# the exact per-run procedure the operator follows interactively. Agent Teams
# are interactive-only; on this host (Ghostty, no tmux) split-pane is
# unsupported, so `--teammate-mode in-process` is mandatory.
#
# Usage:
#   ./run-h3.sh           # print the full 3-run procedure
#   ./run-h3.sh 1|2|3     # print the procedure for a single run
#   ./run-h3.sh cleanup   # remove fixture + team/task state

RUN ${n} — required src/h3.ts state: ${state}   →  expected: ${expected}
────────────────────────────────────────────────────────────────────────────
1. Toggle the source state:
     ${HERE}/toggle.sh ${state}

2. Launch (in-process mode — split-pane unsupported in Ghostty):
     ${LAUNCH}

3. Paste this prompt to the lead:
     ${PROMPT}

4. Observe (keys inside the claude TUI):
     - Shift+Down  → focus/scroll the teammate pane (read its actions + hook feedback)
     - Ctrl+T      → toggle the task list (watch the task status transition)
   Look for: the TaskCompleted hook firing, its exit code, whether the task is
   blocked vs completed, whether the typecheck error reached the teammate as
   feedback, and whether the teammate retried after reading it.

5. Record one JSONL line into ${FIXTURE}/h3-results.jsonl
   (shape: ${FIXTURE}/RESULTS-TEMPLATE.jsonl):
     run 1 expect → hook_exit_code:0, task_status:"completed", blocked:false
     runs 2-3 expect → hook_exit_code:2, blocked:true, feedback_delivered:true,
                        teammate_retried:true, then task_status:"completed" after retry

6. Reset before the NEXT run (fresh team each run):
     ${HERE}/run-h3.sh cleanup      # or just remove the team/task dirs (see cleanup)
     ${HERE}/setup.sh               # rebuild a clean fixture
