+# Task: Integrate remember password into main
+
+## Identity
+
+- Task ID: 20260820-integrate-remember-password-5d7e3a1c
+- Mode: Integration
+- Branch: main
+- Worktree: D:\Datas\OthersProjects\makelore
+- Base commit: 460268586bddbbf75a557012ec872851fca555a5
+- Owner: codex
+- Status: Blocked
+
+## Scope
+
+- Integrate verified remember-password source commit `990639f` into local `main`.
+- Reconcile the source task's accepted authentication promotion candidates into canonical current-state, architecture, ADR, and domain documents.
+- Preserve the pre-existing untracked packaging task record without modifying or committing it.
+
+## Intent And Constraints
+
+- Keep remembered credentials separate from the existing seven-day Works Square session.
+- Keep password persistence Main-owned and OS-encrypted in packaged builds; do not persist passwords in Renderer or Works Square.
+- Preserve logout/SMS retention and successful unchecked-password-login clearing semantics.
+- Merge only to local `main`; do not push.
+
+## Outcome
+
+- Source feature commit `990639f` was created from the completed isolated feature worktree.
+- Merged the source branch into local `main` as merge commit `2b9f84e` without conflicts; README auto-merged with the already integrated Session-model documentation.
+- Promoted the accepted remembered-password boundary into `current-state.md`, `system-overview.md`, ADR-004, and `business-rules.md`.
+- Preserved `.project-docs/30-worklog/tasks/20260819-package-learning-off-115-9c4d.md` untouched and untracked.
+
+## Verification
+
+- Source verification: 79 focused tests, typecheck, scoped ESLint, and Vite Renderer/Main/Preload/utility build passed.
+- Integrated local `main`: 4 focused test files / 79 tests passed.
+- Integrated local `main`: `pnpm run typecheck` passed.
+- Integrated local `main`: scoped ESLint passed with zero errors.
+- Integrated local `main`: Renderer/Main/Preload/utility `pnpm run build:vite` passed with existing dynamic-import and large-chunk advisory warnings only.
+- `git diff --check` passed with line-ending conversion notices only.
+- Required project-docs structure check passed.
+- Task-aware documentation drift is blocked by two read-only foreign task records: the pre-existing, explicitly preserved untracked `.project-docs/30-worklog/tasks/20260819-package-learning-off-115-9c4d.md`, and the source task record `.project-docs/30-worklog/tasks/20260820-makelore-remember-password-b63e1c.md` introduced unchanged by merge commit `2b9f84e`. The integration did not modify either record. The checker also lists the expected merged source files as non-document changes.
+
+## Follow-ups
+
+- Run packaged Windows and signed macOS smoke for OS-protected save, restart prefill, successful unchecked-login clear, and no development Keychain prompt.
+- Resolve the repository's integration drift-check handling for unchanged source task records and decide the separately owned untracked packaging record before this integration ownership can be completed and released cleanly.
+
+## Promotion Candidates
+
+- Applied all accepted source candidates; none remain pending.
