Task: Move Code return navigation into the coding workspace

Identity

• Task ID: 20260929-code-back-entry-33d87a81
• Mode: Feature
• Branch: codex/20260929-code-back-entry-33d87a81-code-back-entry
• Worktree: /Users/chillishark/Makelore 麦洛/.codex-worktrees/makelore/20260929-empty-work-merge-39c633d0
• Base commit: a77ddbd681
• Owner: codex
• Status: Ready for Integration

Scope

• Move the existing “编程 Code” module-home return entry from the project configuration sidebar into the Coding chat/workspace sidebar below the brand. Retain its /module-select target and the configuration page's own back action.

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. 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.

Project Context Loaded

• Task identity: as above, feature mode; ownership verified. Read active task and entry/memory index. Previously loaded positioning, current-state, decision-index, teacher ADR, architecture/domain, evidence, commitments and stale items are unchanged from 5aabaaf, verified by Git diff. Current AGENTS still requires existing light system, local project state and Main-owned APIs.
• Product/context: current main includes empty-work behavior, teacher voice/model controls and compact published shortcuts. This is a small navigation relocation within the existing sidebar; no new visual system is needed. Inspected screenshots, Sidebar, ModuleSwitcher, MainLayout, module route definitions, layout CSS and existing navigation tests.
• Peer scopes reviewed read-only. Active teacher-group-intro and child-language tasks have undefined scope, so coordination context is unknown; neither supplies a known dependency on module-return navigation. Existing teacher/UI tasks are ready. This task owns Sidebar navigation plus focused test/README updates only; no shared canonical docs.
• Relevant behavior: original “编程 Code” ModuleSwitcher navigates to /module-select, not a project reset. /chat uses the classroom sidebar; project configuration and nested resource pages use the generic sidebar. Retain the original target as the user confirmed.
• Gate: Passed. Plan: show the existing module-return control below the Code workspace brand, omit it on /project-config and nested configuration routes, keep a compact accessible layout, adjust the existing navigation regression, run typecheck/lint/build and focused UI verification, review and commit.

Outcome

• Reused the existing ModuleSwitcher beneath the brand in the /chat sidebar, retaining its compact arrow/text style, accessible return-home label and /module-select action. Project configuration and nested resource pages omit the entire sidebar header block, so no empty placeholder remains. Existing configuration back action, sidebar resizing/peek and other module controls are unchanged. README synchronized.

Verification

• pnpm 10.33.4 standard typecheck, changed-file ESLint and production Renderer/Main/Preload/utility build passed. Existing sidebar/peek/module gate and module-navigation unit coverage: 23 tests across four files passed.
• Extended one existing navigation scenario; isolated Electron E2E 1/1 passed. It checks Code return beneath the brand, no sidebar entry on configuration or plugin subpage, configuration back to chat, and collapsed-sidebar hover followed by real navigation to /module-select. Used an independent test profile/ports; no real user application or conversations were changed. Test command: corepack pnpm exec playwright test tests/e2e/main-navigation.spec.ts --grep 'opens remembered Code projects' --reporter=list.
• Inspected chat and configuration screenshots; delegated review also checked collapsed peek. Artifacts are under test-results/main-navigation-Makelore-m-9ce56-instead-of-project-settings/. Independent code review passed; no additional regression found. Whitespace and task-doc drift checks passed.

Follow-ups

• 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.
