 ## Intent And Constraints
 
-- User first requested understanding only, confirmed the two-page interpretation, then explicitly approved implementation. Preserve existing light styling, projects, conversation drafts/history, module access and other module navigation. No live-app update, merge, push or deployment is requested for this new change.
+- User first requested understanding only, confirmed the two-page interpretation, then explicitly approved implementation. Preserve existing light styling, projects, conversation drafts/history, module access and other module navigation. Initial implementation excluded live-app updates. The follow-up explicitly authorizes the temporary Renderer update; main merge, push and formal-app deployment remain outside this change.
 - Reused the clean, completed prior merge checkout after releasing its ready task ownership; old branch/commits remain. Created a new branch at current main a77ddbd, then successfully claimed this new task and verified exact task/mode/worktree/branch/base/reservation. No source from occupied foreign worktrees adopted.

 ## Follow-ups
 
-- Source is ready for integration. Main, remote and the running temporary app were not updated by this new task.
+- Source is ready for integration. The temporary app now includes this navigation change; main and remote remain unchanged.
 
 ## Promotion Candidates
 
 - Target: canonical classroom navigation when next integrated. Proposal: Code module-home return is visible below the chat sidebar brand and omitted from project configuration/resource sidebars; original configuration back remains. Evidence: explicit user confirmation, existing component reuse, actual Electron navigation and screenshots. No architecture or module-target change; no further product confirmation required.
+
+## Follow-up: Update The Temporary Renderer
+
+- User explicitly requested the temporary-app update. Same-task ownership resumed and verified. Existing context is unchanged; active peer scopes read. Two other chats are working on teacher presentation changes; their task records and read-only status show no newly published live version yet. No messages sent to other chats. Recheck launch manifest and process identity immediately before applying this narrowly scoped update; adapt to any newer publication rather than replacing it.
+- Current trial PID 32583 / Host API 54599 uses composer Main 78cfde6 with empty-work overlay, Renderer efd1894 and latest small-card stylesheet fef3b3a. Prepare the navigation patch against this exact generated Renderer source and preserve current Main/profile. Snapshot drafts/auth/project/teacher selection and histories privately, refresh only the Renderer from its existing served directory, and verify the new navigation plus state preservation. Main merge, remote push and formal installed-app replacement remain outside this follow-up.
+- Planning Gate: Passed; only the generated trial artifact and this task record are writable. Keep rollback assets and truthful base/overlay metadata, and never start a model prompt for validation.

+### Temporary Update Outcome
+
+- Updated the existing trial Renderer in place at `/var/folders/mx/ltbgwsks5_n8zllj69p_wbcw0000gn/T/makelore-trial-tdq_nuah/teacher-composer-4f829ac1/source/dist`. Main PID 32583, Host API 54599, isolated profile and native window visibility/focus are unchanged. Formal `/Applications/Makelore.app` was not modified.
+- Detected another chat publishing teacher-group introductions during preparation. Discarded the earlier candidate and rebuilt from its actual published source, preserving fef3b3a prompt/reply styling, 0167d36 empty-work behavior and 7458c37 grouped introductions. Only source difference is `src/components/layout/Sidebar.tsx`, byte-identical to product commit 10b179f; independently reviewed.
+- Final generated source: `code-back-entry-33d87a81/source-with-group-intro` under the trial root; running JS `index-Dh1e8q7U.js`, CSS `index-CA1PKQZ_.css`. Typecheck, scoped lint and Renderer build passed again on this composite source. Launch/guidance metadata and build-source record explicitly retain Main/base/overlay provenance for subsequent updates; old assets and pre-update entry/metadata are retained for rollback.
+- Live verification: Code return button visible on `/chat`; same account, active conversation, selected teacher, teacher content, current Work tab and all 14 consultation drafts. All persisted conversation-history hashes unchanged; one generated runtime prompt manifest refreshed during normal conversation rehydration. Visible virtualized message count changed after rehydration, so full on-screen text equality was not claimed. No model prompt was sent for validation. Configuration and nested-route absence were covered by the preceding isolated Electron E2E.
+- Used the normal lifecycle lease and conversation-selection API to recover an idle runtime after Renderer reload, then released the lease and restored background throttling. Final live state has zero alerts and unchanged visibility/focus. A native screenshot attempt timed out; actual DOM/button presence, source checks and previous isolated visual/E2E evidence were used instead. Verification summary is in the trial update directory's `verification.json`; private snapshots are mode 0600 and never needed for handoff.
