PR Review

Bug-first PR review: report only findings with evidence, reachable impact, and a concrete fix. Prefer silence over false positives.

Step 1 — Acquire Context (run independent reads in parallel)

# If PR number given:
gh pr view <number> --json title,body,files,baseRefName,headRefName,commits
gh pr diff <number>

# If reviewing current branch, determine base first:
git status -sb
git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null || true
git merge-base HEAD origin/<base-branch>
git diff "$(git merge-base HEAD origin/<base-branch>)"..HEAD
git log "$(git merge-base HEAD origin/<base-branch>)"..HEAD --oneline
