 - The repository is public and the product owner chose to publish as is. The in-app update check
  still reads the download page's `version.json` (versionCode 2), so 0.2.1 is not offered there.
 - Verification: the five required checks pass on the merged branch; 471 unit tests, 0 failures.
+
+## 2026-10-12 — TASK-068: app icon shows a tea cup
+
+- Request: the human product owner wanted a different app icon. After several rounds of sketches
+  they chose the current blue background with a small tea cup in place of the Git drawing.
+- What changed: `ic_launcher_foreground.xml` and `ic_launcher_monochrome.xml` draw a small steaming
+  cup with a handle and a saucer line. The background layer is unchanged.
+- Verification: the five required checks pass. Not yet seen on a device (no device was connected).
+
+## 2026-10-12 — TASK-069: in-app motion
+
+- Request: the human product owner asked for the in-app motion items listed after the Claude
+  Motion question, and, while it was being built, for motion on bottom tab switches too.
+- What changed: a new `ui/components/Motion.kt` draws the launcher icon's cup in code and builds on
+  it: a splash over the first second of a cold start, the cup with steam in place of the stock
+  spinner, shimmering placeholder rows while lists load, a bobbing cup on empty screens, a pull to
+  refresh indicator, a spring for the favourite star and the selected tab icon, and a row by row
+  arrival for the first rows of a diff. `MainActivity` wraps the screens in `AnimatedContent`: a
+  pushed screen slides in from the right, a popped one from the left, a tab from the side it sits
+  on. No dependency added.
+- Checks and results: the five required checks pass; 471 unit tests, 0 failures; lint 0 errors.
+- Caution: none of it has been seen on a device (none was connected). Timing and distances are
+  first guesses. During the 90 ms a screen fades out it is drawn from the current view model
+  state, so a screen whose state is cleared on leaving may flash its loading view.
+- Next owner: the product owner, to look at it on the device.
+
+## 2026-10-12 — TASK-070: update check and download from the team's Gitea
+
+- Request: the update notice opened the old password page; the product owner no longer uses that
+  page and asked for Gitea.
+- What changed: `AppUpdateLocations` names `version.json` and `UBGitea.apk` on the `apk` branch of
+  the team's repository; the wording drops the password and the "download page". `version.json`
+  (0.2.1, versionCode 3) was added to the `apk` branch to match the APK already there.
+- Checks and results: the five required checks pass; lint 0 errors. Both addresses answer 200
+  without signing in.
+- Caution: no build with this change is published yet. Copies installed so far still read the
+  old page, so they will not be told about builds published on Gitea; they need one install by
+  hand. `tools/publish-download.py` and the old page are left alone and unused.
+- Next owner: the product owner, to say when a build with the new icon, motion and this change
+  should be published as 0.2.2.
+
+## 2026-10-12 — TASK-071: 0.2.2 published to the team's Gitea
+
+- Request: the product owner asked for 0.2.2 to be published.
+- What changed: version 0.2.2 (versionCode 4) with the tea cup icon, the in-app motion and the
+  Gitea update check. Source pushed to `main`; `UBGitea.apk` and `version.json` on the `apk`
+  branch replaced.
+- Checks and results: the five required checks pass; lint 0 errors. The APK downloaded from the
+  `apk` branch has the same SHA-256 as the one built here.
+- Caution: published without having been seen on a device, at the product owner's decision. The
+  APK is the debug build signed with this PC's key.

+# TASK-068: App icon — a small tea cup instead of the branch
+
+Status: implemented; required checks pass; not yet seen on a device
+Owner: Claude
+Reviewer: human product owner
+
+## Outcome
+
+The app icon keeps its sky-blue background and shows a small white steaming tea cup (the "tea" in
+Gitea) where the Git branch drawing was.
+
+## Scope
+
+- Included: the icon's front layer and its themed (monochrome) layer.
+- Excluded: the background layer, the notification icon, the download page.
+
+## Writable paths
+
+- `app/src/main/res/drawable/ic_launcher_foreground.xml`
+- `app/src/main/res/drawable/ic_launcher_monochrome.xml`
+- `tasks/068-app-icon-tea-cup.md`
+- `docs/development-log.md`
+
+## Acceptance criteria
+
+- [x] The front layer is the cup the product owner chose (option A of the sketches, 2026-10-12):
+  cup, handle, two wisps of steam, saucer line; no Git drawing.
+- [x] The themed layer has the same shape.
+- [x] The drawing stays inside the 66dp safe circle.

+   the steaming cup in place of the stock spinner.
+3. The favourite star springs when its state changes.
+4. A screen with nothing to list shows the cup bobbing above its message.
+5. Entering and leaving a screen slides it a short way in from the side it was opened towards.
+6. Pull to refresh brings the cup down with the finger; the steam appears near the release point.
+7. A file's diff arrives row by row the first time it is shown.
+8. Added while this was in progress (product owner, 2026-10-12): switching bottom tabs slides the
+   screen in from the side that tab sits on, and the tab's icon springs.
+
+## Scope
+
+- Included: Compose's own animation APIs only. No new dependency.
+- Excluded: videos made with Claude Motion; any change to what the screens load or show.

+## Acceptance criteria
+
+- [x] Each of the eight items above is in the code and the app builds.
+- [x] The splash covers the app without delaying it: sign-in, loading and the OAuth callback run
+  underneath, and taps do not pass through the cover.
+- [x] Moving between code tabs, or between pages of one screen, does not replay the screen
+  transition.
+- [x] Nothing animates off screen: the pull indicator composes only during a pull, and the diff
+  rows animate once per file, not on scroll.
+- [x] A list's loading message is still what a screen reader says.
+- [ ] Seen on the product owner's device.
+
+## Security and privacy
+
+No additional concerns. No network, storage or credential code is touched.

+# TASK-070: The app's update check and download use the team's Gitea
+
+Status: implemented; required checks pass; not yet seen on a device
+Owner: Claude
+Reviewer: human product owner
+
+## Request
+
+The update notice in the app opened the old download page, which asks for a password. The product
+owner no longer uses that page (2026-10-12) and asked for the app to use the Gitea link instead.
+
+## Outcome
+
+- The app reads the newest version from `version.json` on the `apk` branch of
+  `RobotAutomationDevelopment-Dept/Ubisam-MobileGit`, and "download" opens `UBGitea.apk` on that
+  branch. Neither asks for a password or a sign-in.
+- The wording no longer mentions a password or a download page.
+
+## Scope
+
+- Included: the two addresses, the wording, `version.json` on the `apk` branch.
+- Excluded: `tools/publish-download.py` and the `choimy0204.github.io/ubgitea/` page. Both are left
+  as they are and are no longer part of publishing.
+
+## Writable paths
+
+- `app/src/main/java/com/ubisam/ubgitea/core/update/AppUpdate.kt`
+- `app/src/main/java/com/ubisam/ubgitea/MainActivity.kt`
+- `app/src/main/res/values/strings_update.xml`
+- `tasks/070-update-from-gitea.md`
+- `docs/development-log.md`
+
+## Acceptance criteria
+
+- [x] No address of the old page is left in the app.
+- [x] `version.json` is on the `apk` branch and names the APK that is there.
+- [ ] Seen on a device: the notice appears for a newer build and "download" fetches the APK.
+
+## Security and privacy
+
+The two addresses are public and are fetched with a client that carries no Gitea token. The
+repository being public was the product owner's choice in TASK-067.
+
+## Publishing a build from now on
+
+1. Raise `versionCode` and `versionName` in `app/build.gradle.kts`, then `assembleDebug`.
+2. On the `apk` branch, replace `UBGitea.apk` and set `version.json` to the same version.
+3. Push the `apk` branch.
+
+Copies installed before this task still read the old page's `version.json`, so they are never told
+about a build published here; they need one install by hand from the Gitea link.
+
+## Required checks
+
+```text
+./gradlew compileDebugKotlin compileDebugUnitTestKotlin testDebugUnitTest assembleDebug lintDebug
+```
+
+## Evidence
+

+# TASK-071: Publish 0.2.2 to the team's Gitea
+
+Status: done
+Owner: Claude
+Reviewer: human product owner
+
+## Request
+
+The product owner asked for the build with the tea cup icon (TASK-068), the in-app motion
+(TASK-069) and the Gitea update check (TASK-070) to be published as 0.2.2 (2026-10-12).
+
+## Writable paths
+
+- `app/build.gradle.kts`
+- `tasks/071-publish-0.2.2.md`
+- `docs/development-log.md`
+
+## Acceptance criteria
+
+- [x] Version 0.2.2, versionCode 4.
+- [x] The source is on `main` of the team's repository.
+- [x] `UBGitea.apk` and `version.json` on the `apk` branch are 0.2.2, and the downloaded APK is
+  byte-identical to the one built here.
+
+## Security and privacy
+
+The APK is the debug build, signed with this PC's debug key, as before. No secret is in it or in
+the push.
+
+## Required checks
+
+```text
+./gradlew compileDebugKotlin compileDebugUnitTestKotlin testDebugUnitTest assembleDebug lintDebug
+```
+
+## Evidence
+
+See the development log entry for TASK-071.
+
+## Review findings
+
+None.
