+# Task: Integrate Web Search unavailable-release diagnostics
+
+## Identity
+
+- Task ID: 20260902-web-search-client-integration-a4c8e291
+- Mode: Integration
+- Branch: main
+- Worktree: D:\Datas\OthersProjects\makelore
+- Base commit: 2c5b60ea78e014a712a47bdbb9efd156f52f3a1d
+- Owner: codex-root
+- Status: Ready for Integration
+
+## Scope
+
+- Integrate exact source commit `2e093bd22c0a3c46cc08b8eede8c1bc02afd690b`
+  from completed feature task `20260901-web-search-runtime-stale-r2-6f4a2d91`.
+- Preserve the two pre-existing untracked package task records byte-for-byte and keep
+  all other client product, package, installed application, and runtime state unchanged.
+- Record the integrated diagnostic boundary in canonical current state and run the
+  source-focused verification plus Integration Documentation Gate.
+
+## Intent And Constraints
+
+- The source commit changes only the mapping of an explicit Marketplace
+  `action='unavailable'`: it must surface `plugin_release_unavailable`, not the
+  unrelated `plugin_runtime_stale` snapshot error.
+- Do not weaken frozen worker, exact Release, Account/project, policy, Admission,
+  Provider, confirmation, or billing checks. Do not install/package/restart the running
+  application, mutate Account/Library/project state, deploy, publish, or invoke a paid
+  Provider.
+- User authorization to take over the client root while preserving unowned files was
+  applied through `--adopt-existing`; the exact pre-existing files remain outside this
+  task's ownership:
+  `.project-docs/30-worklog/tasks/20260901-package-122-c5e8.md` and
+  `.project-docs/30-worklog/tasks/20260901-package-123-d7f3.md`.
+- Concurrent Task Gate: PASS. Integration lock and exact root identity are held for
+  task `20260902-web-search-client-integration-a4c8e291` on `main` at base
+  `2c5b60ea78e014a712a47bdbb9efd156f52f3a1d`; no other task owns this worktree.
+
+## Project Context Loaded
+
+- Project goal: Electron Main remains the authenticated Marketplace and hosted-Plugin
+  authority; Renderer/Pi receive only closed projections from an exact frozen parent
+  worker.
+- Current integrated focus: official bundled Game Resource/Web Search already use
+  account acquisition plus server Release Admission without device package download.
+- Active task scope: integrate one reviewed diagnostic correction and its two-reason
+  regression, then update canonical integrated state.
+- Active constraints: no silent state advancement; no hot swap; no child inheritance;
+  no client-side bypass of Release, Provider, or Token Point authority.
+- Decisions affecting this task: ADR-006 single Pi runtime and logical-thread resource
+  ownership; Marketplace Library, project selection, Agent assignment, Admission, and
+  billing remain distinct states.
+- Evidence/reflections/commitments: the installed `1.2.4` artifact and fresh Pi manifest
+  proved correct tool materialization; live public Marketplace detail proved the server
+  Stable Release was absent. Paid Provider and production deployment remain external.
+- Files involved: hosted Admission resolver, its focused test, source task record,
+  this integration record, and canonical current state only.
+- Other active local tasks: many historical isolated feature/review owners remain in
+  the registry, but none owns this root or the changed hosted-Admission files at the
+  current frontier. The completed source feature is the only semantic input.
+- Unknowns/conflicts: current production Web Search Provider Config/model is not
+  revalidated by this client integration; no semantic conflict or promotion decision
+  is present.
+- Gate result: Passed.
+
+## Outcome
+
+- Cherry-picked the exact completed source as product commit
+  `93e3143e8a427829efc1894317f188868c21803c` on local `main`; source and integrated
+  product trees match for the resolver/test/source-record change.
+- Canonical current state now records the corrected unavailable-Release diagnostic and
+  keeps the server migration/Provider readiness requirements explicit.
+- The two pre-existing untracked package records remain present and unmodified. No
+  installed application, project, Account Library, server, package, or external state
+  was changed.
+
+## Verification
+
+- Source evidence adopted: focused 3 files / 25 tests, TypeScript typecheck, scoped
+  ESLint, diff gate, and feature task documentation gate passed.
+- Post-integration rerun on exact `main`: the same 3 files / 25 tests passed;
+  `pnpm exec tsc --noEmit`, scoped ESLint, and `git diff --check` passed.
+- Integration task-aware document drift and ownership completion are required before
+  closure.
+
+## Follow-ups
+
+- Deploy Works Square commits containing migrations `0078` and `0079`, run Alembic to
+  exact `20260901_official_plugin_compat_0079`, and verify Web Search public detail has
+  Stable Release `00000000-0000-4000-8000-000000000204`.
+- Revalidate the server-owned Web Search Provider Config/model and deployment secret,
+  then reopen the worker. A rebuilt client is needed only to display the improved typed
+  error; reinstalling cannot replace the missing server Release migration.
+
+## Promotion Candidates
+
+- None recorded.
