# Task: Recover Pi integration and merge updater fix

## Identity

- Task ID: 20260826-recover-pi-updater-integration-8f3a6c21
- Mode: Integration
- Branch: main
- Worktree: D:\Datas\OthersProjects\makelore
- Base commit: 48a9189939f3f9a581a76e9d6f5ba2f49879a67c
- Owner: codex
- Status: Completed

## Scope

- Recover the abandoned Pi integration documentation already present in the
  `main` worktree and validate it against the completed Pi source-task records.
- Integrate the updater downgrade-prevention change from source commit
  `2e61800fed793b63b3b7804a03a4c7d8617e23d7` into `main`.
- Verify the focused updater behavior, type safety, lint, and production Vite
  build before handing back the integrated branch.
- Preserve unrelated untracked task records byte-for-byte and outside this
  task's commits.

## Intent And Constraints

- User explicitly authorized force-releasing and taking over the abandoned Pi
  integration task.
- Treat completed source task records as read-only evidence; promote only the
  canonical Pi documentation that is supported by those records.
- Keep unverified Pi release gaps explicit: real Provider execution, macOS
  x64/arm64 packaged artifacts, and native non-WSL Linux remain unverified.
- Apply only the two updater source/test changes from the verified feature
  commit so the feature task record remains source-owned.
- Do not modify, delete, or commit
  `20260819-package-learning-off-115-9c4d.md` or the superseded Pi integration
  task record without separate authority. After the user granted that
  authority, move both files byte-for-byte to a repository-external recovery
  directory.

## Plan

1. Validate the pending Pi canonical documentation against source-task facts
   and current product boundaries.
2. Apply the verified updater downgrade guard and its focused regression tests.
3. Run focused tests, typecheck, scoped lint, and `build:vite`; inspect the
   final diff and commit the integrated result on `main`.
4. Run the Task Documentation Gate, release ownership, and report any remaining
   foreign-record blocker without weakening or bypassing the gate.

## Outcome

- Recovered and semantically reviewed the pending Pi canonical documentation
  against the completed hard-cutover, provider, release-proof, legacy-removal,
  and background-run source tasks.
- Integrated the exact updater source/test change from
  `2e61800fed793b63b3b7804a03a4c7d8617e23d7` into `main` without copying or
  editing its source-owned task record.
- Automatic update channel selection and later channel changes now explicitly
  restore `autoUpdater.allowDowngrade = false`, preventing installed `2.0.0`
  from treating online `1.1.9` as an available update.
- Preserved both unrelated/unregistered task records byte-for-byte and moved
  them to
  `D:\Datas\OthersProjects\makelore-task-record-recovery-8f3a6c21`, outside the
  repository and the integration commits.

## Verification

- Exact source parity:
  `git diff --exit-code 2e61800 -- electron/main/updater.ts tests/unit/app-updater.test.ts`
  passed before task-record finalization.
- `pnpm exec vitest run tests/unit/app-updater.test.ts`: passed, 1 file / 15 tests.
- `pnpm run typecheck`: passed.
- `pnpm exec eslint electron/main/updater.ts tests/unit/app-updater.test.ts`: passed.
- `pnpm test`: passed, 181 regular files / 1543 tests passed / 2 skipped,
  followed by the pressure file with 1/1 passed.
- `pnpm run build:vite`: passed for Renderer, Electron Main, Preload, and the
  release utility worker; existing dynamic-import and large-chunk warnings
  remain warnings only.
- `git diff --check`: passed.
- `check_doc_drift.py --task-id 20260826-recover-pi-updater-integration-8f3a6c21`:
  passed after the user-authorized recovery move; all project-document changes
  satisfy integration ownership boundaries.

## Follow-ups

- The two recovered task records remain available outside the repository at
  `D:\Datas\OthersProjects\makelore-task-record-recovery-8f3a6c21`; restore
  them only if a future task establishes the correct owner and destination.
- Real Provider execution, packaged macOS x64/arm64 artifacts, and native
  non-WSL Linux artifacts remain explicitly unverified Pi release gates.

## Promotion Candidates

- Applied the already-supported Pi hard-cutover facts to the canonical success
  criteria, decision index/ADR, architecture, current state, business rules,
  evidence index, and commitments.
- No additional updater promotion candidate: the updater behavior is captured
  by focused tests and does not change an architectural boundary.
