Verdict: APPROVE

Verification ledger (this turn):

• gh pr diff 222 — change is scoped to package.json + pnpm-lock.yaml; no source files modified.
• git log origin/main..pr-head — single Dependabot commit c54e92a; no rebase/squash surprises.
• gh pr checks 222 — all 11 verdict-affecting checks pass (Vitest, ESLint, TypeScript, Next.js Build, 4× E2E, Analyze Bundle, CodeQL).
• pnpm install --frozen-lockfile — clean against bumped lockfile; +13 -1 packages, explained by jsdom's transitive @asamuzakjp/dom-selector 7.0.10→7.1.1 and cascading postcss/parse5/entities/tldts bumps.
• pnpm vitest run (local, on PR head) — 322/322 tests pass under jsdom 29.1.1, including the MermaidDiagram dialog tests that mock showModal/close (the upstream changes are computed-style fixes — none of the unimplemented APIs the test suite stubs are affected).
• npm registry — jsdom@29.1.1 exists and is published; engines ^20.19.0 || ^22.13.0 || >=24.0.0 are compatible with repo engines.node: >=22 provided CI's Node is on a >=22.13 minor (Vitest job already proves this).

Findings: none.

Bottom line: stock devDependency minor bump (29.0.2 → 29.1.1). Test environment exclusively — jsdom is only referenced from vitest.config.ts and unit tests, never bundled. Release notes are computed-style fixes + a perf optimization, none of which interact with the project's mocked APIs. Safe to queue.

Verdict: APPROVE (re-review on post-fix HEAD)

Verification ledger (this turn, on fd10f22):

• gh pr diff 222 + git log origin/main..pr222-head — two commits: Dependabot's jsdom bump (c02036d) plus Julian's lockfile fix (fd10f22). Fix commit is 3 lines in pnpm-lock.yaml — re-writes the next-view-transitions patch hash from the 64-char hex format Dependabot's pnpm produced to the 26-char base32 format that pnpm@9.15.9 emits.
• git show origin/main:pnpm-lock.yaml — the new hash nxvyby6r4isjnouuw656h2bwdi is byte-identical to what origin/main already carries. The fix doesn't invent a hash; it regenerates the one main expects, which is what pnpm install --frozen-lockfile requires.
• pnpm install --frozen-lockfile on fd10f22 with local pnpm@9.15.9 — clean install, no lockfile mismatch, next-view-transitions.patch applies.
• pnpm vitest run on fd10f22 — 584/584 tests pass in 6.83s under jsdom 29.1.1. The jsdom changes are computed-style fixes for border-radius/background-origin/background-clip and a getComputedStyle() perf optimization; the project's unit tests don't assert on those properties.
• gh pr checks 222 — all 11 verdict-affecting checks green on fd10f22 (Vitest, ESLint, TypeScript, Next.js Build, 4× E2E, Analyze Bundle, CodeQL, CodeQL Analysis).
• Confirmed via gh pr view --json reviews that the prior bot APPROVE on c54e92a is now DISMISSED, as expected once a new commit landed.

Findings: none.

Bottom line: the dismissed-approval signal is mechanically explained by the new commit landing; the new commit itself is a 3-line lockfile regeneration that produces the exact hash main is already using. devDependency-only change (jsdom is referenced from vitest.config.ts and unit tests, never bundled). Safe to re-queue.
