# PR Lifecycle End-to-end workflow for managing a pull request from creation through merge. Consolidates all known patterns and workarounds. ## 1. Pre-Creation Checks Before creating a PR, run these checks (see also [[pre-pr-review]] and [[kookr-pre-push]]): ```bash pnpm build:server # must be clean pnpm check:e2e # must be clean pnpm test # must be green git diff --stat # review — no accidental files, no secrets ``` ### Pre-`gh pr create` duplicate-guard (mandatory) Run this **immediately before every `gh pr create`** below. It aborts with a non-zero exit (no PR is created) if the issue was already auto-closed by an earlier merge, or the head branch already has an open PR or one merged in the last 24h — the exact 2026-07-26 race that produced duplicate PRs (task dd1fbcec, a downstream repo — PRs #1672/#1673/#1674). This gives agents and rehearsals a mechanical stop, not just prose. ```bash # --- Pre-`gh pr create` duplicate-guard (issue #1569) ---------------------- # Fails CLOSED: if a gh probe errors (auth / network / rate-limit) the guard # aborts rather than green-lighting an unverified PR — a rate-limited parallel # batch is exactly when the duplicate race bites. pr_create_guard() { local branch abort n state dupes branch="$1"; shift # head branch of the PR about to be created abort=0 for n in "$@"; do # issue number(s) this PR would close if ! state=$(gh issue view "$n" --json state -q .state 2>/dev/null);
