Runtime-backed APIs route through `LocalRuntimeConnectionPool` (local) or `RemoteConnectionPool` (paired/SSH-bound window); file APIs are strict once a local/remote runtime is bound, while usage/budget reads only route to runtime for remote-bound windows. Usage push delivery follows the active binding too: unbound windows accept main-process usage events, while bound windows accept only the runtime event stream, so a dormant local tracker cannot overwrite the active project's snapshot. During project switches, mutating runtime/sync calls that target the ambiguous active binding are blocked, read-only calls avoid refreshing stale bindings, active remote opens can be awaited before retrying reads, and remote lane preview URLs are localized through desktop-owned TCP forwards. Chat history reads are the exception to the local-IPC fallback: `isRemoteProjectRuntimeContext()` gives a synchronous, transition-safe answer to "is this window's runtime remote?" (live binding → in-flight remote open → the kind snapshotted by `detachProjectBindingForTransition()`), and a remote context returns `unavailable: true` rather than letting the local chat service answer a remote session id with a false `sessionFound: false` that would wipe the transcript. History runtime actions use one object envelope (`sessionId` plus caps/cursor) across preload and ADE Code; the action registry still normalizes the legacy positional form for packaged-client compatibility. If a packaged local window is temporarily bound to an isolated runtime whose sync service is disabled, only the exact machine-level sync-unavailable/register-project failures retry through main-process sync IPC; remote-bound failures never fall back locally. Explicitly targeted work can pass an `OpenProjectBinding` pin through `callPinnedRuntimeAction` to route to the captured project during a switch, used by detached draft launches and rollback. The same pin is the per-session and detached-draft runtime routing mechanism: chat/session calls, the PTY and terminal surface (`pty.create` / `resumeSession` / `sendToSession` / `write` / `resize` / `dispose` / `setDataSubscriptions` / `onData` / `onExit`, `terminal.preview`), plus machine-owned supporting APIs (AI discovery, slash commands, file search, attachments, lane management, parallel launch state, session deltas, and computer-use snapshots) accept an optional `OpenProjectBinding` so foreign work — a CLI or shell session as much as a chat — stays on its owning machine without rebinding the window's tab. Pinned event subscriptions poll the selected runtime when Electron's bound event stream cannot represent a foreign machine, and preload releases a main-side subscription explicitly once its last pump stops reading. Required foreign ownership fails closed; `callPinnedOrBoundRuntimeActionOr` retains the unchanged bound path only when no pin is required. | | `apps/desktop/src/renderer/` | React 18 SPA.

When ADE is launched from a terminal and that terminal goes away, the next write to stdout or stderr raises `EPIPE`; without a listener Node surfaces it as an `uncaughtException`, which funnels into `requestAppShutdown` and tears the whole app down. A dead logging pipe must never kill the app. Any other stream error is still re-thrown. +Renderer crash recovery (`main/rendererCrashRecovery.ts` + the `render-process-gone` handler in `main.ts`): a lost renderer used to be terminal — the window stayed white while the agents behind it kept running, and only a manual app restart brought the UI back. Every reason except `clean-exit` (which is orderly teardown: app quit, window close) is now treated as a renderer to get back, and the window reloads after `RENDERER_RECOVERY_DELAY_MS` (500 ms). Renderer state is rehydrated from the main process, so a reload costs a repaint, not data. Recovery is bounded by `createRendererCrashRecoveryBudget()`: `RENDERER_RECOVERY_MAX_ATTEMPTS` (3) inside a rolling `RENDERER_RECOVERY_WINDOW_MS` (60 s), because the failure it guards against and the failure it could cause are the same shape — a renderer that dies *during boot* would reload-loop forever. The window clock is `performance.now()`, monotonic on purpose: a wall-clock correction mid-crash-storm would either free the budget early or freeze it. When the budget is spent the window stays down, logged as `window.render_process_recovery_abandoned`. The reload targets the canonical `getRendererUrl()` rather than reloading whatever was last committed, so a crash on the load-failure fallback page does not just reload the error page. Each non-`clean-exit` occurrence also reports the `ade_renderer_recovered` product-analytics event (`crash_reason` passed through `coarseRenderProcessGoneReason`, which collapses anything outside Electron's documented reason enum to `unknown` so a future Electron string cannot widen what crosses the analytics boundary, plus whether the budget allowed a reload); the retry budget is what bounds the event volume. + On startup the main process also invokes `recoverManagedOpenCodeOrphans({ force: true })` (see `services/opencode/openCodeServerManager.ts`) to reap previous-run OpenCode processes left behind after a crash. Orphan detection matches processes by the managed marker env (`ADE_OPENCODE_MANAGED=1`) and/or the shared XDG config root, and confirms orphaning either by dead owner PID (`ADE_OPENCODE_OWNER_PID`) or reparent-to-init. Each acquire of a shared OpenCode server also invokes `pruneIdleSharedEntries()` which compacts idle entries from older configs (`pool_compaction` reason). --- diff --git a/docs/features/chat/README.md b/docs/features/chat/README.md index 5c5980ea7..0d71d413c 100644 --- a/docs/features/chat/README.md +++ b/docs/features/chat/README.md @@ -82,6 +82,7 @@ for its separate RPC, sync, storage, and UI contracts. | `apps/desktop/src/main/services/opencode/openCodeInventory.ts` | OpenCode provider/model probe.

The wire variant runs storage compaction first, then drops `structured` and `toolResultMeta` from `tool_result` entirely — no renderer, TUI, web, or iOS client decodes either field, so removing them needs no capability gate. | | `apps/desktop/src/shared/chatSubagents.ts` | Cross-target subagent helpers: `normalizeSubagentLifecycleEvent` (canonicalizes legacy `subagent_*` and dotted `subagent.*` envelopes), the stable `groupPaneSectionItems` partition and pane caps, `buildSubagentPaneRows`, tagged pane click targets, `buildSubagentTranscriptEvents`, `isLifecycleEventForSnapshot`, plus the `latestPlan` derivation. The partition keeps source order, forces pinned rows into the active cap, and excludes visually cleared Completed ids. It also owns the shared subagent-vs-background classification (`isBackgroundShellCommand`, `isRealSubagent`, `isNonAgentTaskRun`, `subagentAgentKey`) — `isNonAgentTaskRun` flags a `task_type` `other` run with no agent metadata (a plain Claude Code task, not a subagent) so both the idle-turn and foreground paths keep it out of the roster. Claude's raw `local_bash` kind is normalized only after explicit background evidence (`background_tasks_changed`, `is_backgrounded`, or `run_in_background`) because foreground Bash emits the same kind. The file also owns summary-quality helpers and `deriveSubagentTimelineRows` → `SubagentTimelineRow` (`spawn` / `result` / `background_chip`) — the portable timeline shape iOS mirrors, not what the desktop transcript renders; that pipeline is `chatTranscriptRows.ts`. Desktop consumes the partition directly; ADE Code consumes the expanded row model; iOS mirrors the same predicates and caps. | | `apps/desktop/src/shared/chatScheduledWork.ts` | Cross-target scheduled-work validation and derivation. `resolveScheduledWorkTiming` accepts exactly one timing form: five-field brain-local cron, offset-qualified absolute `runAt`, or relative `delaySeconds`; it rejects ambiguous, past, non-integer, and unrepresentable schedules before persistence. The rest of the module folds `scheduled_work_update` envelopes into stable snapshots for Claude wakeups, cron tasks, `/loop`, remote triggers, and background work, then merges the transcript projection with the KV-backed management snapshot from `AgentChatSessionSummary.scheduledWork`. The merge removes stale active durable transcript rows that no longer exist in the management store, preserves provider-only/non-durable activity for display, and marks only ADE-managed rows as cancellable. It also partitions rows by surface: `deriveScheduleItems` returns schedule kinds (`wakeup` / `cron` / `loop` / `remote_trigger`) while `deriveBackgroundItems` returns `background_task` rows that do not duplicate a real subagent with the same `sourceTaskId`. A parent turn's terminal event does not coerce surviving background work to stopped; only an explicit work terminal state or runtime teardown does. `isEarlierBackgroundItem`, `isFiredOneShotWakeup`, and `isEarlierScheduleItem` define the shared Earlier membership mirrored by ADE Code and iOS. | | `apps/desktop/src/main/services/chat/claudeWorkflowProgress.ts` | Defensive normalizer for the Claude Agent SDK's undocumented `workflow_progress` snapshot on `system:task_progress` (Workflow orchestration runs).
