open

transaction(tx:open ~ tx:close)은 작업 단위가 아니라 무결성 경계다. tx:open은 "지금부터 전체 상태를 무결하지 않게 만들겠다"는 선언이다.

Lifecycle

tx:open → tx:plan(변경 기록) → tx:apply(구현과 판정) → tx:archive(동결) → tx:close(무결 선언, base로 squash merge). 모두 Skill 도구다. close의 닫힌 상태 gate는 close 시점이 아니라 작업 내내의 규율이다.

열린 상태: 아래가 전부 참이면 transaction은 열린 것이다

• A new branch tx-<slug> is cut from the latest origin/<base> and checked out. The slug is a short kebab-case name for the intent:

  "${CLAUDE_PLUGIN_ROOT}/bin/tx-hook" open-tx <slug>
  

• The seed has run (idempotent). Its artifacts ride this transaction and merge with it:

  "${CLAUDE_PLUGIN_ROOT}/bin/tx-hook" seed
  

• The change is routed. tx:plan takes anything that touches structure or worldview (the repo's design canon); a behavior-preserving refactor that touches structure is still tx:plan's. Only two kinds of change skip openspec: one confined to the docs surface (${CLAUDE_PLUGIN_ROOT}/references/docs-surface.md defines it), and one trivial enough to touch neither.

A failed command's stderr carries the fix; only a failed seed proceeds anyway, on the openspec-skip route.
