From 86bb9cbae1a58d45030bcc7f97774f4a54baf96c Mon Sep 17 00:00:00 2001 From: wgqqqqq Date: Thu, 17 Sep 2026 15:08:51 +0800 Subject: [PATCH 01/13] fix(mobile): tighten sidebar spacing around the mini-apps row The mini-apps row carried 16vp of its own padding on every side while the device section below it added 18vp more, so the gap under the header read as a hole rather than as separation. The row now keeps 4vp above and 8vp below itself and the device section 10vp above it, which lands the header control 20vp above the row and the Devices label 18vp below it inside the shared 76vp header frame. Written into the design contract so the three clients stay on one set of numbers. --- .../kotlin/com/openbitfun/mobile/app/ui/miniapps/MiniApps.kt | 2 +- .../com/openbitfun/mobile/app/ui/shell/sidebar/AppSidebar.kt | 4 ++-- .../openbitfun/mobile/app/ui/shell/sidebar/SidebarHeader.kt | 3 +++ .../app/ui/shell/sidebar/SidebarRemoteWorkspaceSection.kt | 2 +- .../mobile/design-system/components/mobile-components.json | 2 +- .../design-system/preview/generated/mobile-design-data.js | 2 +- .../entry/src/main/ets/pages/components/AppSidebar.ets | 2 +- .../src/main/ets/pages/components/SidebarWorkspaceSection.ets | 2 +- .../mobile/ios/OpenBitFun/Features/Shell/MiniAppsView.swift | 3 ++- .../mobile/ios/OpenBitFun/Features/Shell/SidebarView.swift | 2 +- 10 files changed, 14 insertions(+), 10 deletions(-) diff --git a/src/apps/mobile/android/app/src/main/kotlin/com/openbitfun/mobile/app/ui/miniapps/MiniApps.kt b/src/apps/mobile/android/app/src/main/kotlin/com/openbitfun/mobile/app/ui/miniapps/MiniApps.kt index 747c45189b..63fe76828f 100644 --- a/src/apps/mobile/android/app/src/main/kotlin/com/openbitfun/mobile/app/ui/miniapps/MiniApps.kt +++ b/src/apps/mobile/android/app/src/main/kotlin/com/openbitfun/mobile/app/ui/miniapps/MiniApps.kt @@ -54,7 +54,7 @@ internal fun MiniAppsButton( ) { var open by rememberSaveable { mutableStateOf(false) } if (sidebar) { - Row(Modifier.fillMaxWidth().padding(vertical = 16.dp).heightIn(min = 48.dp) + Row(Modifier.fillMaxWidth().padding(top = 4.dp, bottom = 8.dp).heightIn(min = 48.dp) .clip(RoundedCornerShape(12.dp)).clickable { open = true } .padding(start = 4.dp, end = 8.dp).testTag("sidebar-miniapps"), horizontalArrangement = Arrangement.spacedBy(14.dp), verticalAlignment = Alignment.CenterVertically) { diff --git a/src/apps/mobile/android/app/src/main/kotlin/com/openbitfun/mobile/app/ui/shell/sidebar/AppSidebar.kt b/src/apps/mobile/android/app/src/main/kotlin/com/openbitfun/mobile/app/ui/shell/sidebar/AppSidebar.kt index 9c9e36d61c..88b48e14c7 100644 --- a/src/apps/mobile/android/app/src/main/kotlin/com/openbitfun/mobile/app/ui/shell/sidebar/AppSidebar.kt +++ b/src/apps/mobile/android/app/src/main/kotlin/com/openbitfun/mobile/app/ui/shell/sidebar/AppSidebar.kt @@ -4,7 +4,6 @@ import androidx.compose.foundation.background import androidx.compose.foundation.rememberScrollState import androidx.compose.foundation.verticalScroll import androidx.compose.foundation.clickable -import androidx.compose.foundation.layout.Arrangement import androidx.compose.foundation.layout.Box import androidx.compose.foundation.layout.Column import androidx.compose.foundation.layout.Row @@ -104,11 +103,12 @@ internal fun AppSidebar( var remoteDetailsSessionId by rememberSaveable { mutableStateOf(null) } Box(modifier = modifier.fillMaxSize().testTag(SIDEBAR_TEST_TAG)) { + // No spacedBy: the MiniApps row carries its own 4dp/8dp rhythm, and a + // column-level gap on top of it would push the section header away.

The skeleton was there, but its gate was released when `open` returned — about six milliseconds after the tap — while the records it asked for came over the relay seconds later. The wait now ends when the transcript arrives (a snapshot or an error), not when the command that asked for it returns. The flag is new rather than reused: `isLoadingConversation` means the session itself is not identified yet and blanks the header, which would have left the pane nameless for the whole fetch. `isLoadingTranscript` says the session is known and only its body is on the way, so the header keeps saying which conversation the pane is about and the composer stays usable. A transcript that never lands would otherwise leave a placeholder standing for the rest of the session, so all three clients now cap how long the skeleton may be shown at 20s. Android already closed its gate on the timeline arriving and iOS on `finishRemoteConversationOpenIfReady`; both only needed the cap, and all three share the 140ms grace period. --- .../mobile/app/ConversationViewTest.kt | 15 ++++++ .../mobile/app/ui/chat/ConversationView.kt | 16 +++++- .../ets/pages/components/ConversationView.ets | 10 +++- .../runtime/AppRootRuntimeComposition.ets | 7 ++- .../ets/pages/state/ConversationViewState.ets | 5 ++ .../main/ets/pages/state/RemotePageState.ets | 12 +++++ .../viewmodel/RemoteSessionViewModel.ets | 22 ++++++-- .../main/ets/services/DeferredLoadingGate.ets | 49 +++++++++++++++-- .../src/test/ConversationStateUnit.test.ets | 52 +++++++++++++++++++ .../entry/src/test/LifecycleUnit.test.ets | 41 +++++++++++++++ .../MobileAppModel+RemoteSession.swift | 17 ++++++ 11 files changed, 237 insertions(+), 9 deletions(-) diff --git a/src/apps/mobile/android/app/src/androidTest/kotlin/com/openbitfun/mobile/app/ConversationViewTest.kt b/src/apps/mobile/android/app/src/androidTest/kotlin/com/openbitfun/mobile/app/ConversationViewTest.kt index 1dc74f7ae8..85305328e5 100644 --- a/src/apps/mobile/android/app/src/androidTest/kotlin/com/openbitfun/mobile/app/ConversationViewTest.kt +++ b/src/apps/mobile/android/app/src/androidTest/kotlin/com/openbitfun/mobile/app/ConversationViewTest.kt @@ -288,6 +288,21 @@ class ConversationViewTest { composeRule.onNodeWithTag(CHAT_STATUS_BAR_TEST_TAG).assertDoesNotExist() } + /** + * A placeholder that outlives its subject reads as a hang, so the skeleton + * gives up on a transcript that never lands and lets the pane speak for + * itself.

The host that wrote the path now reads it back when projecting the record stream, so existing conversations show their pictures instead of an empty frame. The read is bounded by what it produces: the bytes have to decode as an image, which settles the type from the content rather than from a recorded mime type and keeps a path aimed at a private file from coming back as base64. An attachment already inside the 100KB mobile budget travels as it was recorded, so a screenshot keeps its transparency instead of being flattened to JPEG; a larger one is resized to 400px and encoded down the quality ladder as before. The read happens off the async runtime's threads. Clients get the mobile fallback too: an attachment whose pixels did not arrive is named rather than drawn, which is the difference between "no image here" and "this image did not sync to this device". --- .../entry/src/main/ets/i18n/EnUsMessages.ets | 1 + .../entry/src/main/ets/i18n/ZhCnMessages.ets | 1 + .../pages/components/ChatMessageContent.ets | 51 +++- .../ConversationMessageRenderPolicy.ets | 10 +- .../ets/services/DurableSessionReducer.ets | 10 +- .../ConversationPresentationUnit.test.ets | 11 + .../feature/session/SessionRecordReplica.kt | 22 +- .../session/SessionRecordReplicaTest.kt | 29 +++ .../core/src/service_agent_runtime.rs | 110 +++++++-- .../src/remote_connect/chat_projection.rs | 87 ++++++- .../src/remote_connect/session_records.rs | 46 +++- .../tests/remote_connect_contracts.rs | 230 +++++++++++++++++- .../src/flow_chat/utils/imagePayload.test.ts | 30 ++- .../src/flow_chat/utils/imagePayload.ts | 53 +++- 14 files changed, 635 insertions(+), 56 deletions(-) diff --git a/src/apps/mobile/harmonyos/entry/src/main/ets/i18n/EnUsMessages.ets b/src/apps/mobile/harmonyos/entry/src/main/ets/i18n/EnUsMessages.ets index 5674f18741..228c89b3e1 100644 --- a/src/apps/mobile/harmonyos/entry/src/main/ets/i18n/EnUsMessages.ets +++ b/src/apps/mobile/harmonyos/entry/src/main/ets/i18n/EnUsMessages.ets @@ -514,6 +514,7 @@ export const EN_US_MESSAGES: [string, string][] = [ ['chat.voiceListeningPlaceholder', 'Listening, please speak...'], ['chat.queuedAfterRunningTurn', 'Queued.

The tree took all of its rows from the session list, and `list_sessions` answers for one workspace at a time — the selected one. Every other bucket was empty by construction, so the branch had nothing to draw and no way to say so. Each branch now fetches its own sessions when it is opened, through the per-workspace directory the store already maintains for that purpose, and the projection carries how far that fetch has got. An empty branch that was never asked reads as loading rather than as a workspace without chats; one whose fetch failed says so and offers a retry; one that came back empty says it is empty. The selected workspace keeps taking its rows from the session list, which is authoritative for it before any branch is asked. Disclosure state is split accordingly: the selected workspace starts open and can be closed, everything else starts closed and opens on a tap, so opening the drawer still costs one `list_sessions` rather than one per workspace. iOS reaches the same tree through the device directory and already disclosed correctly; the only change there is that the directory fixture preview no longer has its account wiped by a signed-out core on launch, which is what made the fixture impossible to inspect. --- .../mobile/app/ui/shell/MobileScreen.kt | 17 +++ .../mobile/app/ui/shell/sidebar/AppSidebar.kt | 7 ++ .../sidebar/SidebarRemoteWorkspaceSection.kt | 100 ++++++++++++++++-- .../mobile/app/viewmodel/AccountViewModel.kt | 13 +++ .../app/src/main/res/values-zh/strings.xml | 2 + .../app/src/main/res/values/strings.xml | 2 + .../MobileAppModel+Account.swift | 4 +- .../shell/RemoteSidebarPresentation.kt | 96 ++++++++++++++--- .../shell/RemoteSidebarPresentationTest.kt | 93 ++++++++++++++++ 9 files changed, 309 insertions(+), 25 deletions(-) diff --git a/src/apps/mobile/android/app/src/main/kotlin/com/openbitfun/mobile/app/ui/shell/MobileScreen.kt b/src/apps/mobile/android/app/src/main/kotlin/com/openbitfun/mobile/app/ui/shell/MobileScreen.kt index 082fd13347..631f0be612 100644 --- a/src/apps/mobile/android/app/src/main/kotlin/com/openbitfun/mobile/app/ui/shell/MobileScreen.kt +++ b/src/apps/mobile/android/app/src/main/kotlin/com/openbitfun/mobile/app/ui/shell/MobileScreen.kt @@ -70,6 +70,7 @@ import com.openbitfun.mobile.core.feature.layout.SettingsPlacementPolicy import com.openbitfun.mobile.core.feature.layout.SettingsSheetKind import com.openbitfun.mobile.core.feature.session.RemoteSessionUiState import com.openbitfun.mobile.core.feature.session.RemoteSessionIntent +import com.openbitfun.mobile.core.feature.session.WorkspaceSessionDirectoryUiState import com.openbitfun.mobile.core.feature.workspace.RemoteFilePreviewUiState import com.openbitfun.mobile.core.feature.workspace.RemoteFileDownloadUiState import com.openbitfun.mobile.core.feature.workspace.RemoteWorkspaceIntent @@ -133,6 +134,7 @@ internal fun MobileScreen() { val accountState by accountViewModel.state.collectAsStateWithLifecycle() val accountRemoteState by accountViewModel.remoteState.collectAsStateWithLifecycle() val accountPhase by accountViewModel.connectionPhase.collectAsStateWithLifecycle() + val accountWorkspaceDirectory by accountViewModel.workspaceDirectory.collectAsStateWithLifecycle() val readyAccount = accountState as?

window fails MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Signing in polls the relay for the minutes the user spends in a browser and a mail app, and a single failed poll ended the whole attempt. That is the window in which a phone most reliably drops its connection, hops between wifi and cellular, or sleeps its radio, so an authorization the user had already granted came back as "sign-in failed" and sent them to the start. A poll that failed for a reason the next tick could get past — a dropped connection, a timeout, a rate limit, a relay that is briefly unavailable — now costs one interval instead of the attempt. Anything the relay meant still stops it: a refused or unparseable transaction stays refused however long the phone keeps asking. A window that runs out while every poll is failing reports that failure rather than a rejected sign-in, because the network is the part the user can act on and the transaction was never actually refused. All three clients carry the same decision, each stated where it can be tested: the shared Kotlin loop is lifted out of its transport so a test can fail polls at it, the HarmonyOS and mobile-web clients gained a transport error distinct from a relay's own answer, and the web test drives a full window on a virtual clock. --- .../main/ets/services/CloudAccountClient.ets | 41 +++++++- .../test/TransportAndGeneralChatUnit.test.ets | 20 +++- .../core/feature/account/AccountStore.kt | 82 ++++++++++++--- .../core/feature/account/AccountStoreTest.kt | 51 ++++++++++ .../src/services/CloudAccountClient.ts | 63 ++++++++++-- src/mobile-web/tests/account-login.test.mjs | 99 +++++++++++++++++++ 6 files changed, 336 insertions(+), 20 deletions(-) diff --git a/src/apps/mobile/harmonyos/entry/src/main/ets/services/CloudAccountClient.ets b/src/apps/mobile/harmonyos/entry/src/main/ets/services/CloudAccountClient.ets index 01006eb76d..887300dd2b 100644 --- a/src/apps/mobile/harmonyos/entry/src/main/ets/services/CloudAccountClient.ets +++ b/src/apps/mobile/harmonyos/entry/src/main/ets/services/CloudAccountClient.ets @@ -46,6 +46,26 @@ export class CloudAccountRequestError extends Error { } } +/** + * Whether a failed sign-in poll should be tried again inside the window. + * + * Retry what the next tick could plausibly get past: a transport failure, and + * a relay that is rate limiting or briefly unavailable.

On a phone that is the majority of the screen spent on chrome that does not change while you read. The transcript now runs the full height of the pane and the header and composer float over it, with the content passing underneath and fading out at both edges. The composer is a capsule inset from both sides; the header stays a full-width bar, because it carries the back, drawer and overflow buttons and a title that needs the width. Nothing is hidden by the float: the transcript reserves the measured height of each layer, so the first and last message still come out from under them, and the measurement follows the composer growing to several lines, the attachment strip appearing, and the permission panel opening. The scroll-to-bottom button rides above the composer instead of behind it. The fade bands do not take touches. Three new geometry tokens carry the contract — the gap between content and each layer, the fade height, and the capsule's side inset — so the three platforms agree on the numbers rather than each picking their own. The blur behind each layer is native where there is one: `BlurStyle.Thin` on HarmonyOS, `.ultraThinMaterial` on iOS. Compose has no first-party backdrop blur, so Android falls back to a 94%-opaque fill of the page colour under the same fade bands, which reads close at a glance but is not a real blur. --- .../mobile/app/ConversationViewTest.kt | 48 ++- .../mobile/app/ui/chat/ComposerBar.kt | 4 +- .../app/ui/chat/ConversationTimelineView.kt | 20 +- .../mobile/app/ui/chat/ConversationView.kt | 335 ++++++++++++------ .../ui/theme/generated/MobileDesignTokens.kt | 6 + .../components/mobile-components.json | 21 ++ .../preview/generated/mobile-design-data.js | 31 ++ .../design-system/tokens/mobile-tokens.json | 10 + .../main/ets/generated/MobileDesignTokens.ets | 4 + .../ets/pages/components/ChatTimeline.ets | 20 +- .../main/ets/pages/components/ComposerBar.ets | 14 +- .../pages/components/ConversationHeader.ets | 11 +- .../ets/pages/components/ConversationView.ets | 172 +++++++-- .../src/main/ets/pages/components/Theme.ets | 9 + .../main/resources/base/element/color.json | 8 + .../main/resources/dark/element/color.json | 8 + .../Features/Chat/ChatTimelineView.swift | 6 + .../Features/Chat/ComposerBar.swift | 8 +- .../GeneratedMobileDesignTokens.swift | 4 + .../Features/Shell/MobileShellView.swift | 124 ++++++- 20 files changed, 690 insertions(+), 173 deletions(-) diff --git a/src/apps/mobile/android/app/src/androidTest/kotlin/com/openbitfun/mobile/app/ConversationViewTest.kt b/src/apps/mobile/android/app/src/androidTest/kotlin/com/openbitfun/mobile/app/ConversationViewTest.kt index 85305328e5..ce2e6c5878 100644 --- a/src/apps/mobile/android/app/src/androidTest/kotlin/com/openbitfun/mobile/app/ConversationViewTest.kt +++ b/src/apps/mobile/android/app/src/androidTest/kotlin/com/openbitfun/mobile/app/ConversationViewTest.kt @@ -25,6 +25,7 @@ import androidx.compose.ui.test.performClick import androidx.compose.ui.test.performTextReplacement import androidx.compose.ui.test.performTouchInput import androidx.compose.ui.test.swipeDown +import androidx.compose.ui.unit.Dp import androidx.compose.ui.unit.dp import androidx.test.platform.app.InstrumentationRegistry import com.openbitfun.mobile.app.ui.chat.CONVERSATION_LIST_TEST_TAG @@ -390,6 +391,44 @@ class ConversationViewTest { composeRule.onNodeWithTag(COMPOSER_SEND_TEST_TAG).assertIsNotEnabled() } + /** + * The composer and the header float over the transcript rather than sitting + * above and below it in a column, so the list runs the full height of the + * pane and these insets are the only thing keeping the first and last + * message out from under them.

Three things were quadratic or repeated where they did not need to be. Reading the transcript filtered the whole round map once per turn and the whole item map once per round, so a session paid for its own length twice over on every record that arrived; the rounds and items are now grouped under their parent once per rebuild. The initial replay of a session arrives one record at a time and rebuilt the entire transcript on each of them, for a screen fenced behind catch-up that nobody could see yet; it now builds once, when the replay is done. And every chunk of a streaming reply rewrote the whole cached transcript, re-encrypting all of it dozens of times a second for a cache nothing reads until the next open; during a turn those collapse into one write per 400ms, and a settled transcript is still written immediately. Nothing is lost by the debounce: the write is cancelled and reissued, and a turn that ends, a session that is closed, and a connection that drops all flush or discard it deliberately. HarmonyOS carries the same two changes in its own reducer and transcript controller. No before/after numbers: the only Android device here runs the app inside a compatibility container whose vsync is broken, so its frame times say nothing about a real phone. The claim is the work removed, not a measured frame rate. --- .../viewmodel/RemoteTranscriptController.ets | 31 +++++- .../ets/services/DurableSessionReducer.ets | 13 ++- .../feature/session/RemoteSessionStore.kt | 75 +++++++++++-- .../feature/session/SessionRecordReplica.kt | 105 ++++++++++++------ .../session/RemoteSessionPersistenceTest.kt | 43 ++++++- 5 files changed, 219 insertions(+), 48 deletions(-) diff --git a/src/apps/mobile/harmonyos/entry/src/main/ets/pages/viewmodel/RemoteTranscriptController.ets b/src/apps/mobile/harmonyos/entry/src/main/ets/pages/viewmodel/RemoteTranscriptController.ets index 6bcc56328a..afc8a004d0 100644 --- a/src/apps/mobile/harmonyos/entry/src/main/ets/pages/viewmodel/RemoteTranscriptController.ets +++ b/src/apps/mobile/harmonyos/entry/src/main/ets/pages/viewmodel/RemoteTranscriptController.ets @@ -19,6 +19,9 @@ import { shortSessionId } from './ConversationRuntime'; +/** Longest a streaming turn's transcript write is held back, in milliseconds. */ +const REMOTE_TRANSCRIPT_CACHE_INTERVAL_MS: number = 400; + export class RemoteTranscriptController { private readonly remote: RemotePageState; private readonly remoteRuntime?: RemoteConversationDependencies; @@ -28,6 +31,7 @@ export class RemoteTranscriptController { private knownRemoteMessageCount: number = 0; private isSyncingAfterTurn: boolean = false; private isRebuildingRemoteTranscript: boolean = false; + private pendingTranscriptCache: number = -1; constructor( remote: RemotePageState, @@ -276,6 +280,10 @@ export class RemoteTranscriptController { resetRemoteTimeline(sessionId: string): void { const runtime = requireRemoteRuntime(this.remoteRuntime); + if (this.pendingTranscriptCache !== -1) { + clearTimeout(this.pendingTranscriptCache); + this.pendingTranscriptCache = -1; + } runtime.timeline.reset(sessionId); this.knownPollVersionValue = 0; this.syncRemoteTimeline(); @@ -314,7 +322,12 @@ export class RemoteTranscriptController { runtime.timeline.applySnapshot(snapshot); this.syncRemoteTimeline(); if (snapshot.messageSnapshot !== undefined) { - this.cacheRemoteTranscript(snapshot.sessionId, true); + // A streaming turn restates the whole transcript on every chunk.
