+# Task: Update trial and merge first-open work preview fix
+
+## Identity
+
+- Task ID: 20261008-merge-work-preview-4b72e9c1
+- Mode: Feature
+- Branch: codex/20261008-merge-work-preview-4b72e9c1-merge-work-preview
+- Worktree: /Users/chillishark/Makelore 麦洛/.codex-worktrees/makelore/20261008-merge-work-preview-4b72e9c1
+- Base commit: d12d214d7f33d6233187f66f592d00ee58ec02f7
+- Owner: codex
+- Status: Ready for Integration
+
+## Scope
+
+- Update the independent temporary app to source d12d214, fast-forward main, push origin/main, and clean this change's source and merge worktrees while retaining branches/commits.
+
+## Intent And Constraints
+
+- User explicitly authorized all four actions and cleanup. Preserve the installed app, its profile and drafts, other task worktrees, and existing global integration lock.
+- Previous trial root was deleted externally; rebuild an independent trial in a stable user-local folder. Copy only project metadata and ordinary settings; no auth/Chromium database/lock copying. New trial requires normal login.
+
+## Project Context Loaded
+
+Task context:
+- Identity fields above verified against official start/status; feature mode, base d12d214.
+- Integration-mode start was rejected by the old classroom-integration lock; it rolled back ownership but left its newly created clean worktree. Official feature claim succeeded on that clean checkout (managed=false). No canonical document changes are planned.
+- 28 peer owner records inspected read-only through registered paths; no new conflicting work. Source is ready and clean; primary main is clean.
+
+Read:
+- Entry/read-before-planning, memory-index, own task and completed source task.
+- Previously loaded positioning/current-state/decisions/architecture/domain/success/evidence/reflection/commitments remain byte-identical from fe1a377 to d12d214; reused that verified context.
+- README/AGENTS and relevant temporary-app startup, profile, authentication and runtime boundaries reviewed.
+
+Relevant understanding:
+- Goal: student creation app with Main-owned browser; this patch only pauses static welcome rendering on Work and restores it on chat.
+- Source product/testing exactly as already verified: 103 unit cases (one unchanged async case passed on file retry), 18 browser cases, one Electron scenario, typecheck/lint/build.
+- Fresh fetch: main and origin/main still fe1a377; source d12d214 directly descends from it, allowing conflict-free FF.
+- Current running PID6483 is installed Makelore, not trial. Old trial directory no longer exists. Isolated new profile/ports allow trial without restarting installed app; login cannot be copied to unpackaged trial.
+- Unknown: live account/game validation awaits user login; no model request will be sent for update validation.
+- Cleanup covers only this source and merge checkout. Explicit user cleanup authorizes normal release/non-force removal for the worktree left unmanaged by the failed official start; branches/commits retained. The managed source uses official retire.
+
+Gate result: Passed.
+
+## Plan
+
+1. Stage the verified complete source/build and an independent Electron bundle outside disposable Git worktrees; open a fresh isolated trial and verify runtime/assets/UI.
+2. Record the runtime outcome, commit this handoff record, fast-forward clean main and push; verify remote SHA.
+3. Retire the managed source and clean the task-created merge checkout after checking no runtime dependency; retain both branches/commits.
+
+## Outcome
+
+- Source d12d214 is included in this handoff branch with no additional product/test edits. Clean main/origin-main at fe1a377 can fast-forward; the following publish step promotes this record together with the verified source.
+- Rebuilt and opened the independent trial at `/Users/chillishark/Library/Application Support/Makelore Trials/work-preview-d12d214`. Source/archive and built Renderer/Main/Preload are independent of both disposable task worktrees; only dependencies link to primary repository node_modules.
+- Trial PID38637, Host API port60966, debugger port60967, dedicated bundle ID and user-data. Normal authentication preserved (E2E skip-setup not enabled); trial is at the login screen and requires the user to sign in again. Project metadata/settings copied as stable validated JSON snapshots; no auth, passwords or Chromium database copied. Installed PID6483 remains running unchanged.
+- Reopen using `打开临时应用.command` in the trial folder; `launch.json` records source/build/PID/ports, and the launcher reuses the running instance or allocates free ports on restart.
+- User-approved cleanup covers only 20261008-work-first-open-8ac7e621 and this merge checkout, after successful remote verification. Both branches and their committed records remain retained; trial runtime files are outside their paths. Managed source uses official retire. The task-created merge checkout left by failed integration start uses official release then non-force Git removal because it was subsequently claimed as unmanaged; no registry flags or foreign lock are changed.
+
+## Verification
+
+- Fresh origin fetch: main=origin/main=fe1a377, d12d214 directly descends from it. Source/merge product, tests and README byte-identical; source verification remains applicable without redundant rebuilding.
+- Source checks: typecheck/scoped lint/build, 103 unit cases (one unchanged async assertion required successful 17-case file retry), 18 browser layout cases, one real Electron fixture scenario; independent review passed.
+- Staged trial dist (131 files) and dist-electron (8 files) match the verified source build byte-for-byte (SHA-256). Running page loads `assets/index-BhQqvIkX.js` from the independent trial path; normal Login button visible at `#/login`.
+- Trial screenshot `/tmp/makelore-work-preview-trial-login.png`; launch metadata under the independent trial root. No model request or user project mutation performed for live smoke; real logged-in game acceptance awaits user sign-in.
+- Task-aware drift check and git diff --check passed. Remote SHA and final cleanup eligibility are checked immediately during promotion/retirement; final receipts are reported to the user and captured in trial launch metadata.
+
+## Follow-ups
+
+- Sign in to the new trial to use account features. Installed-app session and its in-memory drafts remain available in the original process.
+
+## Promotion Candidates
+
+- Carry source task's welcome-visibility proposal for canonical integration later. Canonical files remain unchanged because the existing classroom integration owner retains the repository integration lock; this does not block the user-authorized code merge, push, or bounded cleanup.
