sync shadcn editors blockviewer toolbar

Objective: Implement the accepted sync-shadcn /editors BlockViewer toolbar slice: adopt shadcn /blocks toolbar order and density, keep Plate install/source and Pro behavior, keep Open in v0 excluded, update partial sync tracking without advancing lastSyncedCommit, and verify with focused checks plus browser proof.

Goal plan: docs/plans/2026-05-29-sync-shadcn-editors-blockviewer-toolbar.md

Template: docs/plans/templates/task.md

Primary template: docs/plans/templates/task.md

Applied packs:

• docs (docs/plans/templates/packs/docs.md)
• browser (docs/plans/templates/packs/browser.md)

Task source:

• type: accepted sync-shadcn implementation slice
• id / link: docs/sync/shadcn/runs/2026-05-29-4a4dc8e-to-efdec3c-editors-blocks-style/plan.md
• title: Editors BlockViewer toolbar parity
• acceptance criteria: device/open/refresh group before Plate command pill, refresh reloads preview iframe, no v0 action, Plate install/source and Pro behavior retained, status and plan updated as a partial sync, lint/typecheck and browser proof pass.

Completion threshold:

• apps/www/src/components/block-viewer.tsx uses upstream-style toolbar order: device controls, open-new-tab, refresh, then command/pro action.
• Open in v0 remains absent and no v0 import/action is introduced.
• docs/sync/shadcn/status.json no longer lists toolbar cleanup as deferred for /editors; lastSyncedCommit remains unchanged.
• Focused eslint, pnpm --filter www typecheck, and desktop/mobile browser proof pass.
• Task closure is legal only when the source-of-truth acceptance criteria are satisfied or explicitly narrowed, required verification evidence is recorded, code-review and release-artifact gates are closed when applicable, tracker/PR sync is complete or marked N/A with reason, and node .agents/rules/autogoal/scripts/check-complete.mjs docs/plans/2026-05-29-sync-shadcn-editors-blockviewer-toolbar.md passes.

Verification surface:

• pnpm --filter www exec eslint src/components/block-viewer.tsx --fix
• pnpm --filter www typecheck
• status JSON parse
• Playwright browser proof against http://localhost:3002/editors at 1175x1239 and 390x844
• node .agents/rules/autogoal/scripts/check-complete.mjs docs/plans/2026-05-29-sync-shadcn-editors-blockviewer-toolbar.md

Constraints:

• Preserve existing user-facing behavior outside the task scope.
• Prefer the durable ownership boundary over caller-by-caller patches.
• Do not create PRs, comments, commits, or pushes unless the task/user/skill requires them.
• Do not add broad ceremony when the task is trivial or docs-only.

Boundaries:

• Source of truth: docs/sync/shadcn/runs/2026-05-29-4a4dc8e-to-efdec3c-editors-blocks-style/plan.md
• Allowed edit scope: apps/www/src/components/block-viewer.tsx, sync run plan, sync status JSON, and this goal plan.
• Browser surface: http://localhost:3002/editors.
• Tracker sync: N/A, no external issue.
• Non-goals: no v0, no category nav, no block content import, no full baseline advancement, no app shell changes.

Output budget strategy:

• Use targeted source reads and compact browser metrics; save screenshots under the existing sync run instead of streaming visual evidence.

Blocked condition:

• Block only if upstream/Plate toolbar ownership cannot be mapped, checks fail for reasons outside this slice after one honest retry, or browser proof shows v0 present or preview refresh broken.

Task state:

• task_type: visual toolbar sync
• task_complexity: normal
• current_phase: closeout
• current_phase_status: complete
• next_phase: final response
• goal_status: active

Current verdict:

• verdict: implemented
• confidence: high
• next owner: user review
• reason: toolbar slice shipped with focused checks, iframe-refresh proof, and sync status updated

Completion rule:

• Do not call update_goal(status: complete) while any required checklist item remains unchecked. If an item does not apply, check it and add N/A: <reason>.
• Do not call update_goal(status: complete) until every completion threshold above is satisfied, final handoff evidence is recorded, and node .agents/rules/autogoal/scripts/check-complete.mjs docs/plans/2026-05-29-sync-shadcn-editors-blockviewer-toolbar.md passes.
• Do not create hook state for this goal. This file plus the active goal are the durable state.

Findings:

• Plate toolbar had command/pro action before device controls and no refresh action.
• Upstream toolbar order is device controls, open-new-tab, refresh, command pill, then v0; v0 remains explicitly excluded.

Decisions and tradeoffs:

• Adopted toolbar order, sizing, and refresh behavior.
• Kept Plate install command text/source model and Pro Get the code behavior.
• Did not copy upstream v0 action.

Implementation notes:

• Added iframeKey state to remount preview iframes on refresh.
• Reordered toolbar actions to match upstream /blocks without v0.
• Controlled preview/code tabs from view so toolbar state tracks view changes.
• Fixed the local exhaustive-deps warning by memoizing files.

Review fixes:

• First desktop screenshot caught the refreshed iframe before reload completed; reran browser proof with an iframe-content wait.

Error attempts:

Error / failed attempt	Count	Next different move	Resolution
Browser proof with networkidle	1	Use domcontentloaded plus iframe content wait	Passed
Desktop screenshot captured blank iframe after immediate refresh	1	Wait for iframe heading after refresh before screenshot	Passed
Strict text match inside iframe found two elements	1	Target iframe h1 specifically	Passed

Verification evidence:

• pnpm --filter www exec eslint src/components/block-viewer.tsx --fix passed.
• pnpm --filter www typecheck passed.
• node -e 'JSON.parse(require("fs").readFileSync("docs/sync/shadcn/status.json","utf8")); console.log("status json ok")' passed.
• Browser proof on http://localhost:3002/editors at desktop: device/open/refresh controls visible before command pill, command text is Plate install command, refresh reloads iframe content, Open in v0 absent, no horizontal overflow.
• Browser proof on http://localhost:3002/editors at mobile: no Open in v0, no horizontal overflow.
• Screenshots saved: docs/sync/shadcn/runs/2026-05-29-4a4dc8e-to-efdec3c-editors-blocks-style/screenshots/plate-editors-toolbar-desktop-after.png and docs/sync/shadcn/runs/2026-05-29-4a4dc8e-to-efdec3c-editors-blocks-style/screenshots/plate-editors-toolbar-mobile-after.png.
• Console caveat: known Potion iframe X-Frame-Options/sandbox warnings appeared; there were no page errors or failed requests.

Reboot status:

• Current and complete as of 2026-05-29: toolbar patch, sync bookkeeping, and browser proof are done; final mechanical checks remain.

Open risks:

• None for the accepted slice.

Final handoff contract:

• PR line: N/A, no PR requested.
• Issue / tracker line: N/A, no tracker.
• Confidence line: high; checks and browser proof passed.
• Flow table:
  • Reproduced: N/A for bug repro; source plan and screenshots identified the delta.
  • Verified: focused eslint/typecheck and desktop/mobile browser proof.
• Browser check: desktop refresh/open/device/command order verified; mobile no overflow.
• Outcome: /editors BlockViewer toolbar now follows shadcn /blocks order without v0.
• Caveat: Potion iframe emits known external sandbox/X-Frame warnings.
• Design:
  • Chosen boundary: BlockViewer toolbar owns this behavior.
  • Why not quick patch: refresh needed provider state and iframe key, not just class changes.
  • Why not broader change: upstream v0 and block content remain excluded by policy.
• Verified: eslint, typecheck, status JSON parse, browser proof.
• PR body verified: N/A, no PR.

Task-style PR body contract:

• Preserve any existing <!-- auto-release:start --> block. If a changeset is part of the diff and repo policy expects auto release, include that block.
• Use the accepted kitcn PR #270 visual format. The body starts with an emoji issue/tracker/fix line, for example 🐛 Fixes #123 or 🐛 Fixes ➖ N/A, then an emoji confidence line like 🟢 95-100% confidence.
• Use this exact table header: | Phase | 🧪 Tests | 🌐 Browser |.
• Use Reproduced and Verified rows. Mark passing proof with 🟢, repro or failing proof with 🔴, and non-applicable cells with ➖ N/A.
• Use bold emoji section headings: **✅ Outcome**, **⚠️ Caveat**, **🏗️ Design**, and **🧪 Verified**.
• Never include a line that links to the current PR itself. The current PR URL belongs in the final response, not in its own description.
• Do not replace this with a generic Summary / Verification PR body, an adaptive prose body from a git helper skill, plain ## Outcome sections, or an unrelated generated badge footer unless the caller or repo template explicitly asks for it.
• Proof is gh pr view --json body output or a concise source-backed summary of that output.

Final handoff / sync:

• PR: N/A.
• Issue / tracker: N/A.
• Browser proof: screenshots saved in the sync run folder.
• Caveats: known Potion iframe warnings only.

Timeline:

• 2026-05-29T20:45:59.181Z Task goal plan created.

Reboot status:

Question	Answer
Where am I?	Closeout complete after implementation and verification
Where am I going?	Final response
What is the goal?	Ship shadcn /blocks toolbar parity for Plate /editors without v0
What have I learned?	Toolbar owner is BlockViewer; refresh needed iframe remount state
What have I done?	Patched toolbar, updated sync status/run plan, verified in browser

Open risks:

• None.
