+# Task: Install the server child-friendly replies plugin by default
+
+## Identity
+
+- Task ID: 20260928-default-child-replies-0108dd01
+- Mode: Feature
+- Branch: codex/20260928-default-child-replies-0108dd01-default-child-replies
+- Worktree: D:\Datas\OthersProjects\.codex-worktrees\makelore\20260928-default-child-replies-0108dd01
+- Base commit: efff238a75c1eaba20dba8ae505f47dbea8ba131
+- Owner: codex
+- Status: Ready for Integration
+
+## Scope
+
+- Automatically acquire and install the signed server plugin `makelore.child-friendly-replies` on session activation and Library refresh. Update the Main facade/composition, focused tests, Electron projection acceptance and README.
+
+## Intent And Constraints
+
+- User requests default installation. Preserve account isolation, server-signed immutable artifacts, existing client trusted-key verification and device package lifecycle. Do not turn install into project enablement or Agent assignment. Account removal and default-plugin uninstall are explicit opt-outs.
+- Official check/start/status passed for the isolated feature Identity. Planning Gate passed after own task, entry/memory, positioning/current-state/decisions/architecture/domain/success/evidence and 135 peer coordination records. Positioning still includes template text; AGENTS/README and current source establish product meaning. Old Marketplace tasks overlap paths but preserve the same contracts; no semantic conflict found. Primary main remains owned by integration task `20260928-merge-teacher-cards-a09c07f3` and is untouched.
+- User-provided no-subagent constraint honored. Feature code and mandatory task record only; canonical docs remain unchanged. WS companion task `20260928-default-child-replies-06693309` owns readiness repair.
+
+## Outcome
+
+- Main acquires/downloads only this default plugin through existing Marketplace and Package Store APIs, after confirming a fresh signed compatible Artifact release. Existing installed packages are reused; removed/suspended/stale entries remain unchanged, and failed downloads retry on a later session/list refresh.
+- Facade serializes account operations so an explicit removal during default installation wins, and verifies account binding around queued work. Default-plugin uninstall writes the existing account removal receipt, preventing reinstallation on restart; other plugin/device semantics remain unchanged.
+- Composition starts the normal Library flow when initialized and on session changes. Successful package installation invalidates managed resources through the existing callback. Renderer still receives only safe installation projections; original Skill bytes remain server-delivered.
+- Updated Electron fixture verifies the default plugin appears in the Installed tab without an install click, alongside the existing optional acquisition flow. Updated a stale header-copy assertion to the actual tab landmark for the current embedded drawer.
+
+## Verification
+
+- Red: five default-install facade tests failed before implementation (no install, no opt-out, no retry, no account-switch rejection). Final focused run: 70 unit tests passed across default installation, facade, Marketplace client, routes and plugin composition; separate composition image/background-sleep run: 9 passed (overlap in plugin composition).
+- Six default-install scenarios cover first install, reuse, explicit uninstall/removal, unsigned package deferral, download retry, account change and removal while installation is pending.
+- Pinned pnpm 10.33.4 frozen offline install, standard typecheck, changed-file ESLint and production `build:vite` passed. Electron default Installed-tab/optional acquisition scenario: 1 passed. E2E uses a Main API fixture for display; signed network/package validation remains covered by the existing client tests and companion server acceptance, not a real production install.
+- `git diff --check` passed; final task-aware drift check required before completion. No packaging, installed-app update, push, production mutation or paid call occurred.
+
+## Follow-ups
+
+- Merge verified source after the primary main ownership handoff is authorized. Ship updated client and companion WS startup-signing repair; deploying only the server cannot make an old client automatically install packages.
+
+## Promotion Candidates
+
+- Target current-state and product README: the specific server Skill is installed by default through the signed Marketplace path on session/list refresh, with removal retained and project/Agent controls unchanged. Evidence: focused red/green tests, production build and Electron Installed-tab projection. User requested behavior; no architecture reversal or additional product decision needed.
