Task 03 rebased its branch onto task 01 and flattened the merge into four duplicate commits — but the rule file was *telling* it to: "Before you start: git rebase origin/main". Replaced with merge-based guidance and an explicit prohibition, since a rewritten task branch is the same divergent-history trap that broke the pages branch. Also corrects gates.md tier 3, which promised screenshot comparison in CI that is not wired in and cannot be until visual-regression.mjs grows a compare mode. HANDOVER.md now reflects 01-04 merged, pnpm, and carries forward the review findings that were noted but deliberately not fixed. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
