+# Task: Integrate unified plugin workspace into client main
+
+## Identity
+
+- Task ID: 20260903-plugin-navigation-integration-4f7c2a96
+- Mode: Integration
+- Branch: main
+- Worktree: D:\Datas\OthersProjects\makelore
+- Base commit: e9875145b41a2cb1827de10d27a4fc6a352704ea
+- Owner: codex-root
+- Status: Ready for Integration
+
+## Scope
+
+- Fast-forward client `main` from exact base
+  `e9875145b41a2cb1827de10d27a4fc6a352704ea` through the approved unified Plugin
+  workspace design and reviewed product head
+  `d7058e6383f1e9dd72c32570cf83b9f439d91033`.
+- Promote only the accepted Integration-Gate memory changes: record the unified
+  `/plugins` surface in current state and replace the stale three-page entry in the
+  architecture module map.
+- Preserve the three pre-existing untracked task records in the client root exactly;
+  do not stash, reset, clean, delete, move, or adopt them.
+- Run bounded integration verification, complete the task documentation gate, and
+  release the root integration lock.
+
+## Intent And Constraints
+
+- The fixed product range is
+  `959e2faf03dfacb3c8e2035e44774436c752d4b0...d7058e6383f1e9dd72c32570cf83b9f439d91033`.
+  R4 task `20260903-plugin-navigation-acceptance-r4-9c2f6a41` independently passed
+  Standards and Spec with zero findings.
+- Preserve the existing Catalog, Account Library, official Package Store, Device
+  Package, project enablement, Agent assignment, runtime admission, and billing
+  authorities. This integration changes only the already-reviewed Renderer product
+  and canonical project memory.
+- Keep local Skill/extension installation conversation-only and keep selected-model
+  native Web Search outside the Plugin projection.
+- Related task `20260903-design-message-send-client-8d3f2a71` is Ready for Integration
+  and explicitly excludes Plugin pages, navigation, Sidebar, and router code; no
+  semantic or file ownership conflict exists.
+- Do not push, open a PR, deploy, publish, package, or install a client.
+
+## Project Context Loaded
+
+- Startup memory, integrated current state, decisions, system overview, module map,
+  data flow, business rules, success criteria, glossary, evidence, commitments, and
+  stale-item registry were read from the exact client base.
+- The approved `ML-PLUGIN-NAV-001` specification and the implementation, three
+  remediation, and final R4 acceptance records were read in full.
+- `main` at `e9875145b41a2cb1827de10d27a4fc6a352704ea` is an exact ancestor of the
+  reviewed product head, so the product integration is eligible for `--ff-only`.
+- Concurrent Task Gate: Passed. Planning Gate: Passed.
+
+## Outcome
+
+- Fast-forwarded local client `main` from
+  `e9875145b41a2cb1827de10d27a4fc6a352704ea` to the exact reviewed product head
+  `d7058e6383f1e9dd72c32570cf83b9f439d91033`; no merge conflict or product
+  rewrite occurred.
+- The canonical Code Plugin surface is now one sidebar entry and one `/plugins`
+  workspace. The three old routes remain replace-only redirects and the deleted old
+  page implementations do not remain as fallbacks.
+- Promoted the implementation task's architecture candidate into `module-map.md`,
+  recorded the integrated product and R4 evidence in `current-state.md`, and corrected
+  the obsolete My Plugins wording in the durable Device Package rule.
+- Preserved all three pre-existing untracked client-root task records exactly. No
+  push, PR, deployment, publication, package, or user-machine installation occurred.
+
+## Verification
+
+- Pre-integration ancestry check proved the root base is an ancestor of the reviewed
+  product head; `git merge --ff-only` advanced through exactly five commits (approved
+  design plus implementation and three remediations).
+- Final R4 acceptance record reports Standards PASS and Spec PASS with zero findings
+  over `959e2faf03dfacb3c8e2035e44774436c752d4b0...d7058e6383f1e9dd72c32570cf83b9f439d91033`.
+- Post-merge focused verification passed: 8 files / 83 tests.
+- Post-merge `corepack pnpm run typecheck` passed.
+- Source evidence retained by R4: full unit 1842 passed / 2 skipped plus pressure 1
+  passed; lint 0 errors with 5 pre-existing warnings; all Vite targets passed; targeted
+  Electron Plugin E2E passed 4/4.
+- `check_project_docs`, task-aware document drift, staged diff check, exact branch/HEAD,
+  and final root-status checks are part of the closing gate.
+
+## Follow-ups
+
+- A rebuilt and installed client smoke remains a separate release activity; it was not
+  authorized or required by this source integration.
+
+## Promotion Candidates
+
+- None recorded.
