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.

Ten git worktrees each carried their own 225 MB node_modules (1.1 GB across
five) and paid 11s per `npm ci`. pnpm hardlinks from a shared store: the same
five worktrees cost ~250 MB total, and a fresh install is 4s.
What changed beyond the mechanical rename:
- `overrides` moved to `pnpm-workspace.yaml`. pnpm 11 does not read the `pnpm`
field in package.json *or* npm's top-level `overrides`, and it fails silently
— the vite/defu/language-server pins would have quietly stopped applying.
- Build scripts are blocked by default in pnpm; esbuild and sharp are allowed
explicitly via `allowBuilds` (renamed from `onlyBuiltDependencies` in 11).
- `packageManager` + `engines` pin the toolchain.
- gate.sh rejects a package-lock.json/yarn.lock/bun.lock outright, so an agent
running `npm install` out of habit fails loudly instead of building a second,
divergent dependency tree.
- CI bootstraps pnpm with `npm install --global pnpm@11.25.0` rather than
corepack (unbundled as of Node 25) or pnpm/action-setup (this self-hosted
act-runner has never run a job; fetching a third-party action is not
something to discover on the first one).
Two pre-existing CI bugs fixed while in the file:
- the gate installed with `npm install --package-lock=false`, which discarded
the lockfile the previous session had just fixed.
- the visual-regression step imported `playwright`, which is not a dependency,
and `visual-regression.mjs` has no compare mode anyway — in CI it overwrote
its own baselines and passed unconditionally. Removed with a comment; it
comes back when it can diff.
The `publish` job is now manual (`workflow_dispatch`). During the migration
dist/ holds three HTML files against the live pages branch's ten, so publishing
on every push to main would take the site down to a stub. Restore at task 20.
HANDOVER.md's incident log still says npm where it describes what happened at
the time; that is history, not a missed rename.

Four task branches are green and unmerged, nothing is pushed, and three plan
bugs plus three agent mistakes were fixed along the way. Written so the next
session can pick up without re-deriving any of it.
