+# Task: Merge performance optimization and package 1.1.5
+
+## Identity
+
+- Task ID: 20260819-merge-performance-package-6e5a
+- Mode: Integration
+- Branch: codex/20260819-merge-performance-package-6e5a-merge-performance-package
+- Worktree: D:\Datas\OthersProjects\makelore-integration-performance-package-6e5a
+- Base commit: dd8fbb35380b6baaace0025ae6a6ecf835d462bb
+- Owner: developer
+- Status: Planning
+
+## Scope
+
+- Merge the fetched `origin/codex/performance-optimization` branch into the integration branch based on current `main` (`dd8fbb3`).
+- Build a Windows x64 1.1.5 installer from the merged source with the Learning module disabled.
+- Verify merge ancestry, packaged metadata, artifact integrity, and bundled runtime checks.
+
+## Intent And Constraints
+
+- User explicitly requested the performance branch be merged into `main` before packaging.
+- Keep the original `main` worktree untouched while integrating and building in isolated worktrees.
+- Disable Learning only for the package; do not remove its source or development script.
+- Do not commit build output, downloaded runtimes, caches, or secrets.
+
+## Plan
+
+1. Merge `origin/codex/performance-optimization` into the isolated integration branch and resolve any conflicts without changing unrelated behavior.
+2. Update `main` to the verified merge commit.
+3. Create a packaging worktree from the merged `main`, disable Learning, and build `Makelore-1.1.5-win-x64.exe`.
+4. Run artifact verification and record the installer hash, size, package version, and signature status.
+
+## Outcome
+
+- Not completed.
+
+## Verification
+
+- Not run.
+
+## Follow-ups
+
+- None recorded.
+
+## Promotion Candidates
+
+- None recorded.
