sync shadcn latest

Objective: Create a planning-only sync-shadcn artifact for latest upstream shadcn apps/v4 at cd54e0927f3853a777f700a0bbf34507cf697b9c against Plate baseline 4a4dc8eb0fc793d8e9225e780183ad605f15d2c2, with exact refs, full upstream inventory, reconciled decisions, status update, and completion check. Do not patch apps/www implementation.

Flow mode: Planning mode. Implementation starts only after a later user instruction accepts a named plan and slice.

Goal plan: docs/plans/2026-06-02-sync-shadcn-latest.md

Primary template: docs/plans/templates/sync-shadcn.md

Applied packs: N/A: planning-only sync artifacts; no app/content/package implementation was edited.

Sync source:

• upstream repo: shadcn-ui/ui
• upstream clone: ../shadcn
• upstream app: ../shadcn/apps/v4
• Plate docs app: apps/www
• durable state: docs/sync/shadcn/status.json
• durable policy: docs/sync/shadcn/decisions.md
• run artifacts: docs/sync/shadcn/runs/2026-06-02-4a4dc8e-to-cd54e09/

Completion threshold: Planning is complete when exact base/target SHAs are recorded, ancestry is proven, every upstream added/modified/deleted apps/v4 row is classified in inventory.md, decision counts reconcile to the upstream TSV, recommended slices/questions are recorded in plan.md, lastPlannedCommit points at the target, lastSyncedCommit remains unchanged, no apps/www implementation patch is made by this run, and node .agents/skills/autogoal/scripts/check-complete.mjs docs/plans/2026-06-02-sync-shadcn-latest.md passes.

Verification surface:

• ../shadcn git fetch/log/diff/name-status/numstat evidence.
• docs/sync/shadcn/runs/2026-06-02-4a4dc8e-to-cd54e09/upstream-name-status.tsv, upstream-numstat.tsv, upstream-commits.txt, upstream-latest-name-status.tsv, inventory.md, classification-summary.json, and plan.md.
• docs/sync/shadcn/status.json parse and planned/synced commit semantics.
• Local source mapping through apps/www/package.json, apps/www/src/lib/registry-install.ts, apps/www/src/lib/plate-init.ts, registry scripts, and prior sync policy docs.
• Planning-only no-implementation check for apps/www/content/docs.

Constraints:

• Do not run build:registry.
• Do not patch apps/www during planning.
• Do not edit generated registry output, template output, or generated skill mirrors by hand.
• Do not write broad patch artifacts into the repo.
• Do not advance lastSyncedCommit.
• Preserve settled Plate policy: discard v0/create/charts/colors/theme/customizer product surfaces; keep Plate API MDX, CN docs, MCP, Plate Plus/Pro hooks, GA, home page, editor demos, registry content, lazy registry-source loading, and sidebar accordion/filter UX.

Boundaries: Allowed edits for this run are docs/sync/shadcn/** planning artifacts and this goal plan. Implementation files under apps/www, content/docs, or packages are outside this planning-only run.

Output budget strategy: Large upstream evidence stays in TSV/Markdown artifacts. Chat and command output use counts, summaries, and focused source reads instead of broad patches.

Blocked condition: No blocker. Upstream clone/ref state is valid, target ancestry is proven, all rows are classified, and the only unresolved product decision is isolated as an explicit review question.

Sync state:

• base commit: 4a4dc8eb0fc793d8e9225e780183ad605f15d2c2
• previous planned commit: efdec3ca4523e5edd8a714f633002a7addc203a1
• target commit: cd54e0927f3853a777f700a0bbf34507cf697b9c
• range kind: latest full-range plan from tracked baseline, with latest-only delta recorded from previous plan
• run directory: docs/sync/shadcn/runs/2026-06-02-4a4dc8e-to-cd54e09
• planning status: done
• implementation status: N/A for this run; requires later user acceptance
• user review status: final handoff points at docs/sync/shadcn/runs/2026-06-02-4a4dc8e-to-cd54e09/plan.md
• baseline status: lastSyncedCommit unchanged

Current verdict:

• verdict: planning complete; do not implement all latest rows as one sweep
• confidence: high for accounting, medium for the registry-directory product choice because it needs user acceptance
• recommended next owner: sync-shadcn implementation slice
• reason: latest actionable work is a small registry/package audit, while most upstream rows are excluded/forked product/style churn

Prior migration plans/solution notes checked	yes	Read prior sync plans and solution notes for registry namespace/schema/search/source behavior before classification.
../shadcn clone exists and was fetched/pulled intentionally	yes	git -C ../shadcn fetch origin main --tags succeeded; clone remote is shadcn-ui/ui.
Base and target refs resolved to exact SHAs	yes	Base 4a4dc8eb0fc793d8e9225e780183ad605f15d2c2; target cd54e0927f3853a777f700a0bbf34507cf697b9c from upstream origin/main.
Base ancestry or ref problem proven	yes	Base and previous planned commits are ancestors of target; no ref problem recorded.
Planning-only vs implementation mode decided	yes	Planning-only. No app implementation files are part of this run.
User-review boundary recorded	yes	docs/sync/shadcn/runs/2026-06-02-4a4dc8e-to-cd54e09/plan.md asks review and recommends the first accepted slice.

Work Checklist:

• Objective, threshold, verification surface, constraints, boundaries, and blocked condition are filled from the active goal.
• Upstream range recorded with exact base SHA, previous planned SHA, target SHA, target date, and target subject.
• Run directory created under docs/sync/shadcn/runs/.
• Complete upstream inventories saved: upstream-name-status.tsv, upstream-numstat.tsv, and upstream-commits.txt.
• Latest-only upstream inventory saved as upstream-latest-name-status.tsv.
• Focused diffs inspected on demand and summarized; no .patch files were written into the repo.
• Visual screenshots are N/A because this is a full-range source planning pass with no visual implementation.
• Every changed upstream apps/v4 row is classified in inventory.md with status, path, subsystem, Plate owner, decision, and evidence.
• Decision counts reconcile to the upstream TSV row count.
• Added, modified, and deleted groups are summarized with actionable rows separated from exclusions/no-ops.
• Recommended merge slices are ordered and include class, files, why, and verification.
• Settled exclusions and Plate forks are recorded with policy evidence.
• Real needs-question rows are isolated: the registry directory route/content decision.
• docs/sync/shadcn/status.json update semantics are recorded: lastPlannedCommit, lastPlan, lastFullPlan, and unchanged lastSyncedCommit.
• Planning-mode final handoff explicitly asks the user to review the plan and invoke sync-shadcn again with the accepted plan path and slice.
• Workspace authority recorded for each verification command or artifact.
• Output budget discipline followed; large evidence stayed in artifacts.
• Final handoff shape is filled before closeout.

Recommended merge slices:

Order	Slice	Class	Files	Why	Verification
1	shadcn 4.10.0 package/registry contract audit	adopt-upstream	apps/www/package.json, lockfile, registry schema/import consumers if needed	Lowest product risk; carries current CLI/schema behavior.	pnpm install, source-only registry validation, pnpm --filter www typecheck; no build:registry.
2	Registry directory route decision	needs-question to smart-merge or exclude-upstream	possible apps/www/src/app/r/registries.json/route.ts and Plate-owned directory source	Route is clean but product ownership matters.	If accepted: API smoke and source validation; if rejected: status decision only.
3	GitHub registry docs/concept review	plate-fork / selective smart-merge	Plate registry docs only if accepted	Upstream docs are reference-only; Plate docs should stay Plate-specific.	Docs/browser proof only if content changes.
4	Retained shell follow-up audit	smart-merge	header/mobile/search/docs shell files if a focused hunk maps	Existing partial syncs are mostly done; do not sweep.	Focused source diff, eslint/typecheck/browser only if files change.

Verification evidence:

• Created/updated docs/sync/shadcn/runs/2026-06-02-4a4dc8e-to-cd54e09/upstream-name-status.tsv, upstream-numstat.tsv, upstream-commits.txt, upstream-latest-name-status.tsv, inventory.md, classification-summary.json, and plan.md.
• Row evidence: 790 full-range upstream rows, 56 latest-only rows, 21 upstream apps/v4 commits.
• Decision reconciliation: 1 + 15 + 14 + 616 + 142 + 2 = 790; no hidden decision bucket.
• Status semantics: lastPlannedCommit and lastFullPlan updated to target plan; lastSyncedCommit unchanged at 4a4dc8eb0fc793d8e9225e780183ad605f15d2c2.
• Local source mapping verified Plate currently pins shadcn 4.8.2, uses shadcn/schema, centralizes @plate install commands, and has no current public /r/registries.json route.
• No build:registry command was run.

Reboot status: Current as of 2026-06-02: planning artifacts are written, status is updated to latest planned target, implementation is intentionally not started, and the next run should accept a plan slice before touching app/content/package files.

Open risks: One deliberate open product decision remains: whether Plate should expose /r/registries.json. My recommendation is to defer route implementation until a registry review slice is accepted, because serving upstream external directory content would be wrong for Plate.
