Why the change

远程会话原先只显示文字和附件名,本变更复用现有消息正文,让图片、文件与请求卡片绑定来源 Host 的设备权限和生命周期。

Special things to note

  • Merge risk: two-way door / medium blast radius — shared Web media/cards change, with no database migration; revert this PR to roll back. Review source ownership, trusted content, accepted-only decisions, pending intent/cancellation and Blob release. T1 avatars, T2 read observer, T3 sole request factory/source keys, T7 viewers and T8 settings/model revisions are preserved. R4 was Standards 0 / Spec 1 at 46913; parent closed that P2 after checking the precise failed+Retry delta at 297d9. The T8 rebase has no product conflict or extra product patch. Parent owns CI and merge.
  • Verification at e729105f8731e7d1aa94d0d6bb51c6a53eec0160, base c63947d3e01517552e9fbdd30976af7dee82b0c0: complete build, root+mobile typecheck, lint, format, changelog, docs all exit 0; 34 files / 509 tests pass, including lazy media, refused Close, offline Retry, three former MarkdownText collection entries and T8 settings/model/storage integration. Docs: 624 pages. All four Browser/Computer JS/maps rebuilt naturally and match tracked bytes. CI plan: affected, mobile/docs enabled; new-head CI pending. No 962-file suite. Build/typecheck overlapped by about 6 seconds due to a sub-build completion misread; both GO2, remaining checks serial and Vitest single-worker. Exact logs remain in the task handoff.
  • Runtime screenshots and two-Host proof are historical R8/d78f8c226, not fresh runtime qualification of this head. This round launched no Host/native/model/Docker. Fresh accepted approval and real question reply remain unqualified (UNKNOWN_TOOL, no canonical question card, historical provider 429); OS/banner paths, narrow Activity live integration, native iOS/Android, DSH Desktop and physical-machine tailnet stay in the unified handoff. Host looks are device-local by design. Vain authorized CI-green sequential merging; parent owns final integrated E2E.

Change outline

source Host Journal
  → shared conversation.ts / message-display.ts
  → RemoteMessageBody → existing ChannelMessageBody
       ├─ image → eager source Host resource
       ├─ file/audio → explicit Download/Play → shared pending resource
       └─ request → sole createHostRequestActions → source Host accepted only

Host/Channel change, Close or revocation
  → abort old request + revoke object URL; late result cannot download/play
Offline image reopen → unavailable + shared Retry; no automatic file/audio intent
Refused/missing Host → title + Close remain; no timeline/composer/viewer

Resources use HostClient.resource(path), Device authorization, credentials omitted and no local fallback. The 25 MiB bound matches all production attachment-store construction paths; no Host configuration contract was added. Downloading audio does not play it; render/reconnect does not replay a play intent. Folder errors remain bilingual with their original cause; accepted submissions stay distinct from failed refreshes. Local picker behavior and shared phone transport errors are preserved.

Body screenshots: Before is historical f878c43bb; After was captured during R8 at d78f8c226, with T1/T2 integrated. Images are retained unchanged in the new commit and are not fresh on-demand-media, offline-Retry or T8-integration screenshots. The current Activity/Dock viewer/body transition and lazy/refused/offline-Retry paths have component/shared-conversation regression coverage; live integrated acceptance is deferred to the parent's final E2E per Vain. Saved images are real 1280×800 Web captures, not native-device evidence.

📝 Walkthrough

Remote conversations now use the shared message renderer for message bodies and request cards. Attachment resources and request actions use the source Host. Conversation messages retain their source journal entry to support rendering stored message data.

Changes: Remote message flow

Layer / File(s) Summary
Preserve source message data
apps/mobile/src/host/conversation.ts, apps/mobile/src/host/message-display.ts, apps/mobile/src/host/wire.ts, apps/mobile/src/host/requests.ts, apps/mobile/src/host/attention-actions.ts, apps/mobile/test/conversation.test.ts
Conversation messages retain their source journal entry. The display projection reuses the stored wire message when available, and the test covers rich message fields and the attachment gateway URI.
Load media through the source Host
packages/client/src/client/message-host.ts, packages/client/src/client/message-resource.ts, packages/client/src/client/bridge-*.tsx, packages/client/src/client/bridge-*-resource.ts, packages/client/src/client/message-attachment.tsx, packages/client/src/client/message-audio.tsx, packages/client/test/remote-message.test.ts, packages/client/test/remote-conversation-source.test.tsx
Attachment loading can use the selected Host, with cancellation, retry, size and timeout limits, and object URL cleanup. Bridge media passes the Host to its resource loader. Tests cover source-Host requests, authorization, failure handling, and cleanup.
Render remote messages and route request actions
packages/client/src/client/remote-conversation-view.tsx, packages/client/src/client/remote-message-body.tsx, packages/client/src/client/remote-message-actions.ts, packages/client/src/client/host-activity-actions.ts, packages/client/src/client/channel-message-body.tsx, packages/client/src/client/private-*.tsx, packages/client/src/client/workspace-grants-entry.tsx, packages/client/test/channel-message-body.test.ts, packages/client/test/remote-message.test.ts, packages/client/test/bot-panel-entry.test.ts, packages/client/test/bot-sidebar.test.ts, packages/client/test/channel-dock.test.tsx, .agents/skills/verify-deepseekbot/features/remote-hosts.md, changes/2500-remote-message-body.md, docs/architecture/botharness-architecture.md
Remote messages use the shared body renderer and can display request cards. Remote actions validate the active conversation and route decisions and folder operations through the Host. Tests cover rendering, request outcomes, and ownership checks; documentation describes the remote-message behavior and verification scope.

Merge Risk: 🟡 Moderate · up to 7a443

Opening a remote conversation downloads every visible attachment into memory, and files larger than 25 MiB show as unavailable. When a Host or conversation is refused, the panel now shows only a status line with no Close control. Resolve the attachment loading behavior and restore the header before merging.

Exact-head review note — d78f8c22658c034fddf60ed7480ded6f4ca1cc7c, base 903ea57390a924f37f18d985ff47a514af0629d7.

Source ownership remains: Host Journal → platform-neutral conversation/display → existing ChannelMessageBody; attachments use source HostClient resource credentials; Activity and message cards share one canonical request factory. Host+Channel keys isolate drafts; unmount aborts resources and revokes Blob URLs. Folder failures now use bilingual Web copy while retaining cause and source/ref checks. Accepted submission is distinct from failed refresh.

Parent's R2 Standards and Spec review on fixed ddb4 both returned zero findings. The final delta ports T3's two test-type corrections, fixes two T5 test types and updates current light/dark body screenshots; production behavior is unchanged from the reviewed source after the docs-only main rebase.

Build/typecheck/lint/format/docs each independently exit 0. Related tests: 22 files / 371 pass, including all three old mock collection failures and the folder/source/resource/action regressions. Full docs: 624 pages with a task-local Windows launcher adapter. The first type/format failures are retained rather than hidden. Browser/Computer JS/maps naturally rebuild to identical tracked bytes.

Real two-Host Web evidence proves image/gallery/file bytes, Device-authenticated source resources, source-only send/read, Activity source opening/read refresh, old pending send and draft isolation, and revoke cleanup. All ten Blob URLs created during recording were revoked; two pre-recording URLs were also revoked. Device revocation left no image and no local resource fallback. Owned Hosts are stopped and their homes preserved.

Limits remain explicit: no fresh accepted approval, no real question answer. A trusted fixture using the actual Agent Registry and public ToolRuntime returned UNKNOWN_TOOL for pwsh; public userQuestions.ask waited without a Channel card and was aborted by its bounded timer. One deepseek-v4-pro attempt returned provider 429; no retry. This does not establish the root cause of T3's earlier missing-card case. Narrow Activity has component coverage, not a new narrow-screen live drive. DSH Desktop, physical-machine tailnet and native iOS/Android remain unqualified; Host looks are device-local by design. Historical pending-card images are labelled historical.

An exact-head HTML explainer was generated and inspected at desktop/narrow widths with no renderer warnings or console errors. It is available in the local/parent handoff and thread preview, not a publicly hosted HTML link. This public note and the PR diagram provide reviewer-accessible context; they are not runtime evidence or Human approval.

Refs #2500. Parent owns CI watching and T3-before-T5 merging. No merge or watcher was started here.

Exact-head handoff: 7a443a821bd9f00104bc8974da1d93daab8ae695, base 8fb45a29fa7a33540d5bbc3c048de9562a63e9cb. Refs #2500.

Merged main now includes #2537 canonical Activity/actions, #2548 Expo SDK 58 patch baseline and #2539 viewers. No independent dependency upgrade was made. T5 keeps full ChannelMessageBody rendering, source Host resource credentials, one shared request factory, localized folder failures and Host/Channel draft isolation. T7 viewer buttons and shared viewer modules remain intact; opening a viewer unmounts message media, closing reloads the same source, and changing Host clears the old viewer/draft.

Parent R2 Standards 0 / Spec 0 applies to the earlier ddb4 source. The subsequent T7 conversation-entry merge and two new Activity/Dock lifecycle regressions are explicitly a new integration delta for parent review, not covered by that historical review claim.

Final root+mobile typecheck, lint, format, changelog and docs each exit 0. Related suite: 29 files / 434 tests, including the original 22, seven viewer/auth modules and the three previous MarkdownText collection failures. Full build passed at 7cf11e497; final delta only adds two test override modifiers, with identical production/build inputs. All four checked-in Browser/Computer JS/maps rebuilt naturally with identical bytes. Frozen install and Expo doctor 20/20 passed on the same final dependency inputs. Docs built 624 pages through a task-local Windows launcher adapter. CI plan is affected plus mobile/docs; new-head CI remains pending. No whole-repository 962-file run was attempted. Initial invalid attachment fixture and missing test override failures were corrected and their logs preserved.

The screenshot and real two-Host media/source-read/revocation evidence is historical R8/d78f8c226, not fresh integrated runtime evidence. This round launched no Host, native device, model or Docker runtime. Fresh accepted approval and real question reply remain unqualified: the trusted public owner path returned UNKNOWN_TOOL for pwsh, userQuestions.ask created no canonical Channel card, and one historical model call stopped at provider 429. DSH Desktop, native iOS/Android, physical-machine tailnet and narrow Activity live integration remain unqualified. Host looks are device-local by design. Vain authorized CI-green sequential merging; parent owns merge and later unified E2E. No merge or watcher is started here.

An exact-head Chinese HTML explainer is in the local/parent handoff and T3 thread preview; there is no public HTML hosting link. This public note and the PR diagram provide accessible review context. Historical screenshots retain their capture-head labels.

Review comments at @packages/client/src/client/message-resource.ts:
- Around line 26-60: Update useMessageResource and its MessageAttachment
consumers so remote file resources are not fetched or converted to Blob URLs
during conversation opening; retain eager loading for images, while triggering
file downloads and audio fetches only on user download or playback. Replace the
hard-coded 25 MiB client limit with the configured Host attachment limit so
valid larger uploads remain available.

Review comments at @packages/client/src/client/remote-conversation-view.tsx:
- Around line 239-244: Update the refused-state handling in the remote
conversation view to compute a refused flag instead of returning early. Keep the
shared header and sources.close() control rendered in every state, and replace
only the timeline and composer area with the remoteHosts.interrupted status when
host is undefined or either connection/status value is refused.

本头保留 T1 avatars、T2 source-read、T3 single request factory/accepted-only、T7 viewer 生命周期以及 T8 settings/model revision;新增 lazy file/audio、refused Close 与 offline image Retry 修复均已包含。R4 历史结论是 Standards 0 / Spec 1;父任务核对 297d9 的精确 failed+Retry delta 后关闭 P2,不宣称重新跑过独立全量 review。

完整 build、root+mobile typecheck、lint、format、changelog、docs 均 exit 0。34 文件 / 509 测试通过,含原 22 文件、viewer/auth 与 T8 settings/model/storage 交界;docs 624 页。四份 Browser/Computer JS/maps 自然重建、字节与已提交文件一致,无虚假产物 diff。CI plan 为 affected,mobile/docs 开启;新 CI 待父观察。没有全仓 962 文件测试。执行记录披露:类型检查比总 build 结束早约 6 秒启动(误读子构建完成),两者均 GO2;其后检查串行,Vitest 单 worker。

22:55:32Z 已释放 heavy slot,自有构建/测试进程为 0,47551/47552 无监听。本轮没有 Host/native/device/model/Docker 运行。8 张 GitHub 图片已在浏览器解码验证,均 1280×800;这些是历史 R8/初版卡片截图,不是当前 lazy/Retry/settings 的新运行截图。

fresh accepted approval、真实 question、OS/banner、窄屏 Activity live、native iOS/Android、DSH Desktop、物理双机 tailnet 均留给统一验收。历史 trusted owner 路径 UNKNOWN_TOOL、userQuestions.ask 无规范卡片、provider 429 均不是成功。Host looks 属于 device-local by design。用户已允许 CI 绿后逐个合并;父任务负责合并与最终统一 E2E。

精确 head 中文 HTML 已生成(5 panels、0 warnings),并检查 1200/390 宽度,控制台无错误;它仅为本地/T3 线程交接,没有公开托管 URL。公开 PR 正文及本评论提供相同边界的可访问说明。未开启 watcher 或自行 merge。
