4-Phase 执行

Phase 1 — validate

src="designs/<name>/.handoff/<label>.md"
[ -f "$src" ] || exit 2  # nothing to close

Phase 2 — move (mv 不 rm)

调 Bash：

STAMP=$(date -u +'%Y%m%d-%H%M%SZ')
mkdir -p designs/<name>/.handoff/closed
mv designs/<name>/.handoff/<label>.md designs/<name>/.handoff/closed/<label>_${STAMP}.md

Phase 3 — append_log

LINE=$(printf '{"ts":"%s","action":"close","label":"%s","reason":"%s"}' \
  "$(date -u +'%Y-%m-%dT%H:%M:%SZ')" "<label>" "<reason>")
echo "$LINE" >> designs/<name>/.handoff/handoff_log.jsonl

Phase 4 — gh (optional)

if [ "<close-gh>" = "true" ] && command -v gh >/dev/null 2>&1; then
  gh issue list --label "<label>" --state open --json number \
    | python3 -c "import sys,json; [print(i['number']) for i in json.load(sys.stdin)]" \
    | xargs -I{} gh issue close {} --comment "Closed by bb-close-issue: <reason>"
