Desktop context inspection could send get_context_usage while a prewarmed CLI process existed but before the SDK socket was connected. That first control request sat in the pending outbound queue and could time out, leaving the composer spinner or a misleading empty-state context display. The server now waits for the SDK socket before sending control requests, and the UI renders the actual initial context snapshot instead of masking empty active-session data.
Constraint: CLI /context and desktop get_context_usage must stay on the shared collectContextData/analyzeContextUsage path
Rejected: Hide zero-token active snapshots in the component | that masks backend timing bugs and prevents showing real initial system/tool context
Confidence: high
Scope-risk: narrow
Directive: Do not queue control requests before the SDK socket is connected; let user messages keep the pending outbound behavior
Tested: bun test src/server/__tests__/conversations.test.ts --test-name-pattern "not queue control|context-only|prewarmed empty session|structured session inspection"
Tested: cd desktop && bun run test -- pages.test.tsx --test-name-pattern "EmptySession shows draft context|first-paint spinner|empty live session|live context usage|runtime model"
Tested: bun run check:server
Tested: cd desktop && bun run lint
Tested: real dev API prewarmed empty session returned 31,190 / 262,144 (12%) on first context-only inspection and 16ms on repeat
Tested: browser at http://127.0.0.1:5174/ showed 上下文用量 12% for an empty active session
The desktop composer now treats draft and not-yet-running sessions as pending
until a real CLI context snapshot exists. Context inspection has a lightweight
context-only path so the composer and /context panel do not wait on unrelated
usage or MCP status work, and desktop boot no longer blocks the first shell
render on tab restoration.
Constraint: Empty composer state has no live CLI context to inspect until a session starts
Rejected: Display 0% before live context exists | it implied one user message consumed the fixed prompt/tool baseline
Confidence: high
Scope-risk: moderate
Directive: Do not show numeric context usage without a real context snapshot
Tested: cd desktop && bun run test -- pages.test.tsx

Tested: Browser reload at http://127.0.0.1:5174 with cleared open-tabs showed pending context and no /inspection request
Teach provider presets and saved providers to carry per-model context windows so auto-compact uses provider-specific limits instead of a blanket fallback. The desktop provider form now keeps these limits in an advanced context section and syncs the generated settings preview with model changes.
Constraint: Third-party provider APIs do not consistently expose machine-readable model context windows.
Rejected: Keep a single 100K/200K fallback | modern provider windows vary from 128K to 1M+ and the fallback caused late or early compaction.
Confidence: high
Scope-risk: moderate
Directive: Do not change provider compact thresholds without re-running real provider long-context checks.
Tested: bun test src/services/compact/autoCompact.test.ts; bun test src/server/__tests__/provider-presets.test.ts src/server/__tests__/providers.test.ts src/server/__tests__/providers-real.test.ts; bun run check:server; bun run check:desktop; bun run check:policy; bun run check:native; MiniMax/Kimi/DeepSeek live long-context probes; agent-browser provider form flow.
Not-tested: quality:pr policy gate still requires explicit allow-cli-core-change for CLI core edits.
Desktop failures were previously hard to debug from issue reports because server-side and CLI startup details were only partially visible in the UI. This adds a dedicated cc-haha diagnostics store with sanitized structured events, runtime error summaries, a Settings diagnostics view, and an exportable bundle that users can attach to reports.
Constraint: Diagnostic exports must not include chat content, file contents, full environment variables, API keys, bearer tokens, cookies, or OAuth tokens.
Rejected: Export raw server logs | easier to debug but too likely to leak secrets and private workspace data.
Rejected: Keep diagnostics only in transient UI errors | still leaves maintainers unable to diagnose later GitHub issues.
Confidence: high
Scope-risk: moderate
Directive: Do not add raw transcript, prompt, attachment, or environment dumps to diagnostics without a separate privacy review.

Not-tested: Destructive clear-logs button in browser E2E; local deletion was intentionally not clicked.
The session inspector now asks the resumed CLI for a fast structural context estimate instead of forcing the full token-counting API path. This preserves live CLI state for system prompt, tools, MCP tools, skills, and messages while avoiding the 20s timeout that made historical sessions appear stuck or fall back to transcript-only estimates.
Constraint: Inspector requests must return quickly for third-party providers and historical resumed sessions.
Rejected: Increase the server timeout | the slow path can still block on provider token counting and keeps the UI feeling broken.
Confidence: high
Scope-risk: narrow
Directive: Keep interactive inspector context on the estimateOnly control path unless the UI explicitly supports a slow precise refresh.

Tested: agent-browser automation verified no loading/error and visible System prompt/System tools/MCP tools/Messages
Not-tested: bare root tsc --noEmit, because current tsconfig scans existing desktop/src-tauri/target generated binary assets unrelated to this change
Desktop slash commands now separate local UI panels from CLI turn execution. The session inspector exposes status, usage, and context data from the active session, including transcript and context fallbacks, so /status, /cost, and /context can render structured desktop UI instead of raw terminal text. The inspector and help surfaces now use the existing desktop i18n catalogs for English and Chinese labels.
Constraint: Desktop read-only slash commands must not spawn duplicate CLI processes or depend on submitting a normal user turn.
Rejected: Render raw CLI command text in chat | it keeps terminal-specific layout constraints and does not fit the desktop panel UX.
Confidence: high
Scope-risk: moderate
Directive: Keep /status, /cost, and /context routed through the local inspector unless the CLI exposes a structured interactive command protocol.

A desktop session can pass the startup grace window and then lose its CLI subprocess before a result arrives. Previously that path only deleted the active process record, leaving the WebSocket client in an active turn with no terminal message. The process-exit handler now emits a synthetic CLI error result through the existing translation path so the UI receives both an error and message_complete. The mock SDK fixture can reproduce post-startup exits, and the integration test locks the terminal event behavior.
Constraint: The frontend already relies on result is_error translation to emit error plus message_complete.
Rejected: Add a separate WebSocket process-exit message type | it would duplicate existing result-error handling and require another frontend state path.
Confidence: high
Scope-risk: narrow
Directive: Keep process-exit failures on the same result-error path unless the client protocol gains a dedicated terminal error event.
Tested: bun test src/server/__tests__/conversations.test.ts
Tested: cd desktop && bun run lint
Tested: agent-browser against http://127.0.0.1:1421 with mock CLI late exit; page showed CLI process exited unexpectedly and composer became editable again
Desktop session interruptions were leaving two different classes of stale UI
artifacts behind: reconnects could silently lose in-flight output, and history
reloads could replay synthetic interruption or internal command breadcrumbs as
if they were user-facing transcript content. This change rebinds active session
output to the latest client websocket on reconnect, preserves queued outbound
messages across transient disconnects, and filters synthetic transcript entries
before they reach the desktop history API so reloads reconstruct only the
messages users should actually see.
Constraint: Desktop transcript history is shared with CLI JSONL files and must stay compatible with persisted message shapes
Rejected: Hide these artifacts only in React renderers | other transcript consumers would still receive polluted history
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep transcript filtering aligned with real synthetic/internal message shapes before adding new hidden message types

Not-tested: Manual browser verification of the refreshed session transcript after interrupt on this exact session
This folds together the desktop-side fixes needed before broader rollout.
Session resume no longer deadlocks waiting on init, Mermaid and inline image
output render inside chat, task and sub-agent state stay visible during
execution, local build/release paths are safer, and Feishu/Telegram now expose
lightweight mobile commands (/help, /status, /clear) without adding a new
adapter-specific protocol.
Constraint: Desktop releases must publish updater artifacts from non-draft GitHub releases
Constraint: IM commands need short, phone-friendly responses and low operational complexity
Rejected: Add a dedicated IM command API surface | re-used existing slash commands and session/task REST endpoints to keep adapters thin
Rejected: Wait for task_update push events in WebUI | added low-risk polling because the current frontend ignores that event path
Confidence: medium
Scope-risk: broad
Reversibility: clean
Directive: Keep IM command replies terse and mobile-first, and merge local fallback slash commands when server-provided lists are partial

The desktop app now keeps the composer stable while turns are active,
reduces low-signal tool noise in the transcript, restores project context
under the composer after session creation, and relies on the CLI's own
permission requests instead of injecting broader desktop-side Bash asks.
This also brings in the supporting desktop app source tree and the server
routes/session metadata needed for git info, filesystem browsing, session
resume, slash commands, and SDK-backed permission bridging so the UI can
operate as a coherent feature instead of a partial patch.
Constraint: Desktop transcript needs to stay usable during long multi-tool sessions without hiding file-change diffs
Constraint: Permission prompts must mirror CLI behavior closely enough that read-only commands do not get desktop-only prompts
Rejected: Keep rendering Read/Bash bodies inline | too noisy and unlike the intended transcript model
Rejected: Commit only the touched desktop files | would leave the newly introduced desktop app incomplete in git history
Confidence: medium
Scope-risk: broad
Reversibility: messy
Directive: Treat non-writing tools as summary-first transcript events; do not re-expand them by default without validating the UX against long sessions
