+# Task: Build 1.2.1 from newest main
+
+## Identity
+
+- Task ID: 20260901-package-121-7a3c
+- Mode: Feature
+- Branch: main
+- Worktree: D:\Datas\OthersProjects\makelore
+- Base commit: 143aaec3d6770dd263bf1e418e89bf722989caef
+- Owner: codex
+- Status: Completed
+
+## Scope
+
+- Build and verify the Windows x64 1.2.1 installer from the latest local `main` commit (`143aaec3d6770dd263bf1e418e89bf722989caef`). No source changes are in scope; the deliverable is the packaged artifact and its verification evidence.
+
+## Intent And Constraints
+
+- Use the pinned pnpm toolchain and frozen lockfile. Produce the unsigned Windows x64 NSIS installer, preserving the repository's existing Electron/Pi runtime packaging contracts and current main-branch behavior.
+- On 2026-09-01 the human explicitly authorized `codex-root` to take over this
+  completed task solely to preserve and commit its known untracked task record,
+  then release the occupied `main` worktree for the separately verified
+  Conversation-abort integration. Do not rebuild, relabel, overwrite, or otherwise
+  change the existing 1.2.1 artifact during this closure.
+
+## Outcome
+
+- Produced `release\Makelore-1.2.1-win-x64.exe` from `main` at `143aaec3d6770dd263bf1e418e89bf722989caef` (295,115,852 bytes).
+- Packaged artifact contains version `1.2.1`, Learning code, Web Search and Marketplace code, `.makelore/project.json` integration, and no legacy `learning-player` files.
+- Pi product artifact verification passed for Pi `0.84.2`, 130 packages, 6 assets, packaged plugin/runtime closure, and resolver/runtime checks.
+- Human-authorized closure preserved the task record on `main` without changing
+  product source, dependencies, release output, installed data, or artifact bytes.
+
+## Verification
+
+- `pnpm install --frozen-lockfile` passed.
+- `pnpm run package:stage:win-x64` passed.
+- Electron Builder Windows x64 build passed.
+- `pnpm run verify:publish-runtime` passed (npm `11.6.2`).
+- `pnpm run verify:artifact:win -- --allow-dirty --installer .\\release\\Makelore-1.2.1-win-x64.exe` passed; Electron `43.4.0`, Node `24.18.1`, Python/uv/npm resources and native modules verified.
+- `pnpm run verify:artifact:pi -- --app-exe .\\release\\win-unpacked\\Makelore.exe --samples 2` passed; final result `pass` with cold/warm readiness and packaged closure evidence.
+- ASAR inspection passed: version `1.2.1`, `learningEnabled=true`, Web Search/Marketplace/config markers present, `legacyLearningPlayerFiles=false`.
+- Installer SHA-256: `3578A3643BF715C57EF924D75819240D97D2387DB7300546735384DA06B26E49`; Authenticode status `NotSigned` (local unsigned build).
+- `smoke:pi:real` and `perf:pi:release` were not rerun; their existing harness still asserts two parent process IDs while current main intentionally uses one long-lived parent Agent Server with logical runs/leases.
+
+## Follow-ups
+
+- External code signing and publication remain follow-ups if a distributable signed release is required.
+- Align the Pi smoke/performance harness assertion with the one-parent Agent Server architecture before claiming those checks as passing.
+
+## Promotion Candidates
+
+- None recorded.
