 # Settings View Implementation Handoff (2026-03-18)
 
-## Completed Tasks Summary
+## Task 9 Outcome (Required vs Actual)
 
-- Executed final quality gate verification commands in the `settings-side-panel` worktree.
-- Captured current git short status after verification.
-- Recorded outcomes and follow-up needs for handoff.
+Required final quality gate scope:
+
+1. Run verification suite:
+   - `./gradlew :app:test`
+   - `./gradlew :app:assembleDebug`
+   - `./gradlew :app:lintDebug`
+2. Check short git status (`git status --short`).
+3. Produce handoff note with evidence and deferred items.
+
+Actual outcome:
+
+- **Succeeded:** `:app:test` and `:app:assembleDebug` completed with `BUILD SUCCESSFUL`.
+- **Failed (blocking):** `:app:lintDebug` completed with `BUILD FAILED` due to 3 lint errors.
+- **Succeeded:** short status captured (`?? .kotlin/`).
+- **Succeeded:** handoff note written in this worktree and committed.
+
+## Reproducibility Anchors
+
+- **Run context:** local CLI run in worktree `/home/micost/Documentos/Repos/Kanbn4Droid/.worktrees/settings-side-panel`.
+- **Run date:** 2026-03-18.
+- **Commands executed exactly:**
+  - `./gradlew :app:test`
+  - `./gradlew :app:assembleDebug`
+  - `./gradlew :app:lintDebug`
+  - `git status --short`
+- **Output source:** all evidence in this note comes from those local command outputs in this same worktree.
 
 ## Verification Evidence Summary
 
-- `./gradlew :app:test` -> **PASS** (`BUILD SUCCESSFUL`), included `:app:testDebugUnitTest` and `:app:testReleaseUnitTest`.
-- `./gradlew :app:assembleDebug` -> **PASS** (`BUILD SUCCESSFUL`), `:app:assembleDebug` was up-to-date.
-- `./gradlew :app:lintDebug` -> **FAIL** (`BUILD FAILED`), lint reported 3 errors and 89 warnings.
-  - First blocking error:
-    - File: `app/src/main/java/space/hackenslacker/kanbn4droid/app/settings/SettingsPreferencesFragment.kt:25`
-    - Issue: `RestrictedApi` for calling `Preference.performClick()`.
-- `git status --short` after verification:
-  - `?? .kotlin/`
+- `./gradlew :app:test` -> **PASS** (`BUILD SUCCESSFUL`), including `:app:testDebugUnitTest` and `:app:testReleaseUnitTest`.
+- `./gradlew :app:assembleDebug` -> **PASS** (`BUILD SUCCESSFUL`), `:app:assembleDebug` up-to-date.
+- `./gradlew :app:lintDebug` -> **FAIL** (`BUILD FAILED`), reported `3 errors, 89 warnings`.
+- `git status --short` -> `?? .kotlin/`.
 
-## Deferred Items
+## Lint Blocking Errors (All 3)
 
-- Resolve `lintDebug` blocking errors before release-quality completion.
-- Decide whether `.kotlin/` should remain untracked or be ignored consistently across contributors.
+1. `app/src/main/java/space/hackenslacker/kanbn4droid/app/settings/SettingsPreferencesFragment.kt:25`
+   - Error: `RestrictedApi` (`Preference.performClick()` call on `KEY_BASE_URL`).
+   - Remediation hint: avoid direct `performClick()`; trigger editable preference flow through supported public APIs (for example direct navigation/focus flow or extracting edit logic into app-owned method).
+
+2. `app/src/main/java/space/hackenslacker/kanbn4droid/app/settings/SettingsPreferencesFragment.kt:26`
+   - Error: `RestrictedApi` (`Preference.performClick()` call on `KEY_API_KEY`).
+   - Remediation hint: same fix strategy as above; remove restricted API calls and replace with app-side explicit edit action.
+
+3. `app/src/main/res/layout/item_card_activity_timeline.xml:27`
+   - Error: `UseAppTint` (`android:tint` used).
+   - Remediation hint: replace `android:tint` with `app:tint` and ensure `xmlns:app` is declared on the root element.
+
+## Deferred Items with Exit Criteria
+
+1. Clear lint blocking errors.
+   - Exit criteria:
+     - `./gradlew :app:lintDebug` exits 0.
+     - lint report shows `0 errors`.
+   - Suggested next commands:
+     - `./gradlew :app:lintDebug`
+     - `./gradlew :app:test`
+     - `./gradlew :app:assembleDebug`
+
+2. Resolve `.kotlin/` untracked handling policy.
+   - Recommendation: keep `.kotlin/` out of version control and add/confirm ignore coverage in repo-level `.gitignore` for deterministic clean status.
+   - Exit criteria:
+     - `git status --short` no longer reports `.kotlin/` after a fresh local build/test run.
+     - `.kotlin/` is not tracked in commits.
+   - Suggested next commands:
+     - `git status --short`
+     - `git check-ignore -v .kotlin/`
