+# Task: Plugin navigation R3 detail retry remediation
+
+## Identity
+
+- Task ID: 20260903-plugin-navigation-remediation-r3-f3a8c4d1
+- Mode: Feature
+- Branch: codex/20260903-plugin-navigation-remediation-r3-f3a8c4d1-plugin-navigation-remediation-r3
+- Worktree: C:\Users\7brot\.codex\worktrees\plugin-nav-remediation-r3-f3a8c4d1\makelore
+- Base commit: 0bfabc0df24fdd41c37af498f7a4e49bc00d31db
+- Owner: codex-01a0656d
+- Status: Ready for Integration
+
+## Scope
+
+- Remediate the R3 detail-loading retry loop against exact product base
+  `0bfabc0df24fdd41c37af498f7a4e49bc00d31db`.
+- Make automatic official-detail loading selection-scoped: at most one automatic
+  request per detail open, a stable local error after rejection, and one new
+  attempt after explicitly closing and reopening the same detail.
+- Add a public Renderer/page regression for reject/settle and close/reopen, while
+  preserving the existing A-to-B late-detail protection.
+- Produce one remediation commit and a clean READY_FOR_INTEGRATION handoff.
+
+## Intent And Constraints
+
+- Follow the authoritative ML-PLUGIN-NAV-001 Spec, especially section 5.4 and
+  ERR-001/ERR-005 in section 7.2, plus the exact R3 acceptance finding supplied
+  by the source task.
+- Work test-first through the public `Plugins` Renderer/page seam.
+- Limit product edits to `src/pages/Plugins/index.tsx` and the necessary focused
+  plugin page test. This task record is the only project-document write owned by
+  the task.
+- Do not modify stores, Electron Main, server, runtime, billing, router, Login,
+  dependencies, or any other worktree/root checkout.
+- Do not add a cache, persistent authority, compatibility layer, feature flag,
+  broad retry framework, or speculative UI.
+- Do not merge main, push, create a PR, deploy, publish, or install the app.
+
+## Project Context Loaded
+
+- Product goal: close the R3 P1 finding without changing the unified plugin
+  workspace's authority boundaries or its existing R1/R2 behavior.
+- Current state: exact HEAD and merge-base are
+  `0bfabc0df24fdd41c37af498f7a4e49bc00d31db`; only this newly created task
+  record is untracked. Marketplace `loadDetail` sets `loading`, then `error` and
+  rejects on a supported request failure. The current page effect observes that
+  error and immediately calls it again.
+- Relevant decisions: official detail is loaded on demand; source failures must
+  remain local and stable; Renderer must not create a second cache or retry
+  authority; stale A detail must never replace selected B.
+- Evidence inspected: the complete ML-PLUGIN-NAV-001 Spec, current project
+  memory, the R2 task record, `src/pages/Plugins/index.tsx`, the Marketplace
+  store detail transition, and existing public page/model tests.
+- Likely modules: `src/pages/Plugins/index.tsx` and
+  `tests/unit/plugins-page.test.tsx` only.
+- Risks: an already-loading detail must count as the current open's automatic
+  attempt so a later failure cannot trigger a compensating request; changing or
+  clearing selection must reset the attempt boundary without weakening store
+  generation protection.
+- Concurrent task assessment: task_context identity, worktree, branch, and base
+  match exactly. Remaining Planning peers are old Marketplace/ML-07 reviews or
+  unrelated modules and declare no ownership of this page/test or retry
+  semantic. Concurrent Task Gate: Passed. Planning Gate: Passed.
+
+## Outcome
+
+- `Plugins` now records the official detail selection's automatic attempt before
+  observing later `loading` or `error` state. A rejected request therefore
+  settles as one stable local detail failure instead of immediately starting an
+  unbounded retry loop.
+- Clearing selection resets that local attempt boundary. Closing and reopening
+  the same official detail permits exactly one new automatic request; changing
+  A to B likewise establishes B's own attempt without changing Marketplace
+  store generation or late-result protection.
+- The public page regression drives the real route composition, reproduces the
+  supported store `error` transition, proves one call while open, observes the
+  existing detail error surface, closes the dialog, and proves one additional
+  call only after reopening.
+- No store, Electron Main, server, runtime, billing, router, Login, dependency,
+  or unrelated product file was changed.
+
+## Verification
+
+- TDD RED: `tests/unit/plugins-page.test.tsx` reported the new contract failure
+  exactly: `loadDetail` expected 1 call after the detail error settled but
+  received 2 (13 existing tests passed, 1 new test failed).
+- TDD GREEN: `tests/unit/plugins-page.test.tsx` passed 14/14.
+- Focused plugin suite (`plugins-page`, projection model, query, controller):
+  4 files / 39 tests passed, including the existing A-to-B late-detail model
+  regression and the prior R1/R2 behavior.
+- `pnpm run typecheck`: passed.
+- `pnpm run lint:check`: passed with 0 errors and 5 pre-existing warnings in
+  `src/pages/Home/index.tsx` and `src/pages/Makelore/index.tsx`, outside this
+  diff.
+- `pnpm test`: 225 files / 1842 tests passed / 2 skipped; the separately run
+  coding-chat pressure test passed 1/1.
+- `pnpm run build:vite`: Renderer, Electron Main, Preload, and utility worker
+  builds passed. Existing Browserslist age, mixed static/dynamic import, and
+  large-chunk warnings remained non-failing.
+- Targeted Electron E2E (`plugin-marketplace.spec.ts` and
+  `project-plugins.spec.ts`): 4/4 passed after the script's production rebuild.
+- `git diff --check`: passed; the product diff is limited to
+  `src/pages/Plugins/index.tsx` and `tests/unit/plugins-page.test.tsx`.
+
+## Follow-ups
+
+- Source task will run a fresh fixed-range R4 Standards + Spec review. Do not
+  merge to main before that independent acceptance.
+
+## Promotion Candidates
+
+- None recorded.
