+# Task: Fix missing official plugin acquire and download action
+
+## Identity
+
+- Task ID: 20260905-plugin-download-action-6c8e4a21
+- Mode: Feature
+- Branch: codex/20260905-plugin-download-action-6c8e4a21-plugin-download-action
+- Worktree: D:\Datas\OthersProjects\.codex-worktrees\makelore\20260905-plugin-download-action-6c8e4a21
+- Base commit: 9ed9bf4a715e300420e7a764a4cf576a6dfc4938
+- Owner: codex-root
+- Status: Ready for Integration
+
+## Scope
+
+- Reproduce and fix the unified `/plugins` projection for the code-owned bundled
+  `makelore.project-scaffold` Plugin when the Account Library has not acquired it.
+- Keep the existing acquisition, device-package, project-enablement, and Agent
+  assignment authorities separate; cover the public Renderer seam with a focused
+  regression test.
+- Limit product changes to the unified Plugin workspace projection/presentation and
+  its focused tests unless the reproduction proves the fault is owned elsewhere.
+
+## Intent And Constraints
+
+- A bundled Project Scaffold Plugin never has a device download/update/uninstall
+  action. Before acquisition it must offer the existing free Account Library acquire
+  action; after acquisition it may offer project enablement and Agent assignment.
+- Do not add a visible local package/Skill installation picker, change server/Main
+  contracts, or collapse Account Library acquisition into device installation.
+- Preserve the occupied client root worktree and its three adopted untracked task
+  records exactly. Work only in this isolated feature worktree.
+- Concurrent Task Gate: Passed. Planning Gate: Passed after loading the current
+  integrated state, ADR-008, Plugin business rules/module boundaries, and the completed
+  root Project Scaffold integration task. No active product writer overlaps this scope.
+
+## Outcome
+
+- Added one shared projection predicate for code-owned bundled official Plugins and
+  used it on both the unified Plugin card and detail dialog. An unacquired bundled
+  Project Scaffold now reports `随应用提供` rather than the false
+  `未下载官方包` state.
+- Preserved the existing authority boundary: the client does not synthesize a
+  Marketplace catalog entry or acquisition action. The existing `免费获取` action
+  still appears only when the server catalog contains the Plugin and the authenticated
+  Account Library snapshot confirms it is not acquired.
+
+## Verification
+
+- TDD red: the new public Renderer regression failed because both card and detail
+  reported the bundled Plugin as not downloaded.
+- Focused green: `plugins-page` plus `plugin-workspace-model` = 35 passed.
+- `corepack pnpm run typecheck`: passed.
+- Scoped ESLint on the three changed product files and focused test: passed.
+- `corepack pnpm run build:vite`: passed for Renderer, Main, Preload, and utility
+  targets with existing size/import warnings.
+- Full unit run: 225 files / 1887 passed / 2 skipped, with one unrelated real-process
+  timing threshold failure (`2657ms < 2000ms`). The exact failed file then passed 6/6
+  in isolation; the separately skipped pressure suite passed 1/1.
+- `git diff --check`: passed.
+
+## Follow-ups
+
+- Deploy the current Works Square server revision and migrate production through
+  `20260904_project_scaffold_0085`; until then the live catalog has no authority to
+  offer `免费获取` for `makelore.project-scaffold`.
+
+## Promotion Candidates
+
+- None recorded.
