-## 2026-10-12 (continued) — TASK-069: the start no longer stutters as the cup leaves
-
-- Request: the product owner reported that at launch the cup seemed to move off towards the top
-  left as it disappeared, and that this part stuttered.
-- Cause found in the code: until the session is known the route shown is the repository list;
-  once it is known the route becomes Home. Both are tabs, so the change played the full-width tab
-  glide, at about the moment the cover was fading, on top of Home's first composition.
-- What changed: `MainActivity` gives that hand-over a plain fade and no slide. `SplashOverlay`
-  takes `settled` and, after its own 1.1 seconds, waits until the session is known (at most 1.5
-  seconds more) and for the fade underneath before it leaves.
-- Checks and results: the five required checks pass.
-- Caution: diagnosed from the code, not seen on a device. If the stutter is still there, the
-  remaining suspect is the cost of Home's first frames on that phone.

-- Request: going from 홈 to 알림 went straight there; the product owner wants it to glide
-  quickly past 저장소 and 작업.
-- What changed: the four tab screens are pages of one `TabPager` (`Motion.kt`), which a tab
-  press scrolls with 320 ms plus 50 ms per extra tab passed; swiping is off, so gestures inside
-  the screens are unchanged. In `MainActivity` the tab routes share one `AnimatedContent` key,
-  and the two-screen tab glide there is removed. Entering and leaving other screens is as before.
-- Design decision: a tab that is only passed shows whatever its ViewModel last held (its list,
-  or its loading state if never opened); it is not loaded for the pass.
-- Checks and results: the five required checks pass.
-- Caution: not seen on a device.
-
-## 2026-10-12 (continued) — TASK-075: small interaction fixes
-
-- Request: the product owner asked for a border on the selected timeline chip, no tea cup on
-  short loads, a question before leaving from 홈, a button back to the top of long lists, and
-  said that sideways moves looked diagonal (top left to bottom right), also at launch.
-- What changed: `Chips.kt` wraps Material's FilterChip with a selected border and the five
-  screens import it; `CenteredLoading` shows its cup only after 450 ms (`AfterShortWait`);
-  `ExitConfirmDialog` is shown by Back on 홈; `ScrollTopLazyColumn` replaces the LazyColumn of
-  the list screens; `NoResize` is applied to the route transition and to `TabGlide`.
-- Design decision: the diagonal drift is attributed to AnimatedContent's default size animation,
-  which grows from the top left; this was not confirmed on a device before the change. The exit
-  question was designed in code in the app's style, not on the Claude Design canvas first.
-- Agents: chips and the exit dialog were written by implementer (sonnet); the rest by main (opus).
-- Checks and results: the five required checks pass.
-
-## 2026-10-12 (continued) — TASK-069: pushes, steadier repository tabs, tabs kept composed
-
-- Request, from the product owner's device: opening a repository from 활동 중인 저장소 flickered
-  and should push in from the right while it loads; after sliding between the repository tabs
-  something seemed to refresh or realign; tab moves should have no stutter at all.
-- What changed: `MainActivity` opens and closes screens with a full-width push (300 ms) in place
-  of the 90 ms fade. `RepositoryListScreen` remembers what each tab last showed and keeps showing
-  it through Loading, so the account line, the organisation chips and the rows no longer vanish
-  and return on a tab change, refresh or page turn. `TabPager` keeps all four tabs composed
-  (`beyondViewportPageCount`), and gives the tabs not being shown a Back dispatcher nothing
-  presses, so a hidden tab cannot answer Back.
-- Design decision: a remembered list may be a moment out of date (a favourite just starred);
-  the fresh one replaces it in place when it arrives. It is dropped on sign-out.
-- Checks and results: the five required checks pass.
-- Caution: what is installed for these looks is the debug build, which Compose runs noticeably
-  less smoothly than a minified release build; the published APK is the same kind (R8 is on hold
-  under TASK-016). Remaining stutter may be that and not the transitions.
-
-## 2026-10-12 (continued) — TASK-069: the stall at the start of every move
-
-- Request: the product owner asked that the stutter be looked at on their phone directly. It was
-  driven over adb (taps, Back) and measured with `dumpsys gfxinfo framestats` and method
-  sampling (`am profile`), on the debug build, on the 120 Hz cover screen.
-- What was found: every move began with one frame of 45 to 118 ms (5 to 14 frames lost).
-  1. `LocalCodeWorkbench` is a static composition local and its value was built again on every
-     recomposition of the root, which every route change causes. A changed static local turns
-     skipping off beneath it, so all four tab screens were composed again on each move.
-  2. The loading placeholder's light and the empty screen's cup kept animating on the tabs kept
-     composed off screen: the app drew 120 frames a second while nothing moved.
-  3. Changing repository tab built the incoming list of rows in the frame the slide started on.
-  4. A repository's branches replaced the list in place, with no movement, and Back built the
-     whole list again in one frame.
-- What changed: the workbench value is remembered and made again only when its contents change.
-  `LocalOnScreen` tells a page whether it is on screen and the looping animations stop when it
-  is not. `MainActivity` hands the screens remembered callbacks and a remembered screen lambda.
-  The two repository lists sit in a `TabPager`, and so do the list and the branches of the
-  repository opened from it; branches that arrive during the slide wait for it to finish.
-- Measured, first frame of the move, before to after: bottom tabs 80–118 ms to 23–34 ms;
-  repository tab 69–77 ms to 34–52 ms; idle, 120 frames a second to none.
-- Not measured: the branches opening beside the list, and Back from them. The phone's screen was
-  turned off before that run; the change builds and passes the checks but has not been seen.
-  Before it, opening was a cut followed by a 49–59 ms frame when the branches arrived, and Back
-  was a cut with one frame of 69–105 ms.
-- Design decision: the branches screen now slides in like a pushed screen, where it used to
-  replace the list at once. This is a visible change made for smoothness and is the product
-  owner's to keep or reverse.
-- Checks and results: the five required checks pass.
-- Caution: what remains (about 25 to 50 ms on the first frame) is in good part the debug build;
-  a non-debuggable build of the same code measured about a third less. R8 is still on hold
-  under TASK-016.
-
-## 2026-10-12 (continued) — TASK-069: rows keep their lines between repository tabs
-
-- Request: the product owner turned the screen back on for the measurement left open, and
-  reported that going between 전체 저장소 and 즐겨찾기 kept changing the lines of text.
-- Measured, the branches beside the list: opening starts with a frame of 30–42 ms and slides for
-  the full 390 ms, and the rows are built in one 52–64 ms frame after the slide has stopped;
-  Back starts with 13–17 ms and slides without a slow frame (it was a cut with 69–105 ms).
-- What was found: a capture taken 120 ms into the slide showed every row saying
-  "마지막 push 브랜치 확인 중…". Each load of the list began every row at that text and
-  replaced it with the branch chip when the check returned; the chip is taller and, with a long
-  branch name, pushes the date to a line of its own, so each row changed height twice per move.
-- What changed: `RepositoryListViewModel` keeps the branch last found for each repository and a
-  list loaded again starts its rows with it, still checking every row for a newer one. A check
-  that fails leaves a known branch in place. The record is dropped with the session.
-- Measured after: the same capture shows the chips in place during the slide; the repository
-  tab change starts with 35–53 ms and has no frame over 25 ms after it.
-- Checks and results: the five required checks pass.
-
-## 2026-10-12 (continued) — TASK-069: opening from 활동 중인 저장소, and Back from it
-
-- Request: the product owner reported a hitch on pressing a card under 활동 중인 저장소.
-- Measured on their device over adb, before: opening had a frame of 79–95 ms about 220 ms into
-  the 300 ms push, when the file list arrived and its twelve rows were built at once; Back
-  began with a frame of 119–123 ms. The screen transition dropped the tab pager when a screen
-  covered it, so Back built all four tab screens again in its first frame.
-- What changed: `PushedOver` in `Motion.kt` takes the transition's place in `MainActivity`. The
-  tab pager stays composed under a screen opened from it, moved off to the left with the same
-  curve as the push; covered, it answers no Back, is hidden from accessibility and nothing in
-  it loops. `heldWhilePushedIn` gives the branch screen its code and history state as they stood
-  when it began to push in until it has arrived.
-- Measured after: opening has no slow frame between the first (52–72 ms, building the screen)
-  and the end of the push, and the rows are built in one 80–111 ms frame once it stands still;
-  Back begins with 35–66 ms and has no slow frame until it has stopped.
-- Checks and results: the five required checks pass.
-- Caution: the first frame of opening is not shorter; it delays the push's start and does not
-  interrupt it.
-- Follow-up the same day: the product owner, on a release build, found the screen often still
-  loading after it had arrived. The state was held 80 ms past the push and then took a frame
-  to build. It is now released 40 ms before the push ends, where the screen has under 2% of
-  its way left, so the list is there as the screen stops.
-
-## 2026-10-12 (continued) — TASK-076: 0.2.5 published, as the release build
-
-- Request: the product owner asked for the work so far to be published as a new version, and
-  for the release build to be the one published.
-- What changed: version 0.2.5 (versionCode 7) with TASK-069's motion and TASK-075's fixes. The
-  release build type is signed with this PC's debug key, the key every published build has
-  had, so `assembleRelease` gives an APK that installs over them. Source pushed to `main`;
-  `UBGitea.apk` and `version.json` on the `apk` branch replaced.
-- Why the release build: measured on the product owner's device, the same code's first frame
-  of a move was 52–72 ms as the debug build and 21–29 ms as the release build.
-- Checks and results: the five required checks and `assembleRelease` pass; lint 0 errors. The
-  release APK's signing certificate is the debug APK's. Installed over 0.2.4 on the product
-  owner's device as an update, it starts signed in and opens a repository. The APK downloaded
-  from the `apk` branch has the same SHA-256 as the one built here.
-- Caution: R8 is still off (TASK-016) and no baseline profile is included; both were explained
-  to the product owner, who put them off. The in-app update from 0.2.4 is used for the first
-  time by this version and was not watched on a device.

-    showing each tab's last list while it reloads, so nothing settles after the glide. All four

-    lists stay built side by side; a repository's branches open beside the list and not in place
-    of it; nothing that loops is drawn while it is off screen.
-14. Reported by the product owner (2026-10-12): going between 전체 저장소 and 즐겨찾기 changed
-    the lines of text in the rows. Each row keeps the branch it was last found to have been
-    pushed to while the list is loaded again, where it went back to "확인 중" and then to the
-    branch, changing the row's height twice.
-15. Reported by the product owner (2026-10-12): pressing a card under 활동 중인 저장소 hitched.
-    Measured: the file list was built in one long frame while the screen was still pushing in,
-    and Back began with a frame of about 120 ms because the four tab screens, dropped when the
-    screen covered them, were all built again. The tab screens now stay as they were under a
-    screen opened from them, and what loads during a push is shown once the screen stands still.

-## Outcome
-
-1. A selected filter chip is outlined in the brand colour, everywhere chips are used.
-2. A short load shows no tea cup: the cup appears only after 450 ms of waiting, so opening a
-   repository from 활동 중인 저장소 goes straight to the code when it loads quickly.
-3. Back on 홈 asks before leaving the app (계속 사용 is the default; 종료 leaves), with the
-   question alone: no explanatory line under it.
-4. A list scrolled a long way down offers a small round button that returns it to the top.
-5. Screens that move sideways no longer drift diagonally: `AnimatedContent` is told not to animate
-   its own size (it does so from the top left corner).
