api_retry heartbeats already reach the desktop status bar, but the
streaming-to-non-streaming fallback had no signal at all: the CLI only
flipped an internal flag, and the one-shot fallback response can take
minutes with zero incremental output, so the UI showed a bare spinner
the whole time.
- CLI: yield a {type:'system', subtype:'streaming_fallback', cause}
message at both fallback sites (stream error/watchdog and 404 stream
creation), mirroring the existing api_error -> api_retry path through
query.ts passthrough, QueryEngine SDK output, and the SDK schema.
- Server: translate it to a streaming_fallback ServerMessage;
unrecognized causes normalize to 'unknown' instead of dropping the
event.
- Desktop: track it as active-turn state (cleared at the same 12 sites
as apiRetry; a fallback notice supersedes the stale retry banner) and
render a neutral pill with the turn timer - expected state, not an
error, so no amber styling and nothing in the diagnostics panel.
- Retry banner now shows "retrying now" once the countdown elapses
instead of sticking at "waiting 0s".
With 62241a31 disabling the non-streaming fallback for desktop CLI
sessions, this notice mainly covers the 404 gateway path (which skips
the disable check), callers that re-enable fallback via env, and
non-desktop SDK consumers.
Constraint: Retries and fallbacks are expected states per the
diagnostics severity standard - lightweight active-turn UI only, no
error-panel entries, no transcript persistence.

Not-tested: live provider outage reproduction; verified via unit
coverage of the translation, store lifecycle, and indicator rendering.
Desktop sessions can receive task tools, background-agent lifecycle events, and child tool stream events in the same turn. The UI now keeps root Agent cards separate from task-management tools, preserves parent links when later stream events omit them, and surfaces completed background-agent result text from task notifications.
Constraint: Existing desktop session history can contain task-notification XML and live WS events with incomplete parent metadata.
Rejected: Render local_agent lifecycle messages as standalone cards | duplicates the Agent tool card and makes ownership unclear.
Confidence: high
Scope-risk: moderate
Directive: Do not collapse Agent and TaskCreate/TaskUpdate root tools into one generic group without checking multi-agent screenshots.

Tested: Real gpt-5.5 desktop E2E sessions under /tmp/cc-haha-subagent-e2e-20260519-025454 for 3 subagents, child tools, result dialog, and background Bash completion.
Not-tested: Full bun run verify gate.
The /goal command already exposes description and argument hints in the CLI. Revert the broader SDK, system/init, and server metadata changes so the remaining behavior change is only the desktop fallback and rendering path.
Constraint: Desktop help should not require changing core CLI or SDK wire contracts.
Rejected: Add slash_commands_metadata to system/init | unnecessary for the reported desktop-only display issue.
Confidence: high
Scope-risk: narrow
Directive: Fix missing desktop slash command descriptions in desktop fallback/rendering unless the CLI wire contract is explicitly being redesigned.

Goal commands already had local CLI metadata, but desktop and SDK init consumers only received a name list. Keep the legacy slash_commands string array intact and add explicit metadata so clients can render descriptions and usage hints without breaking older readers.
Constraint: Existing SDK/system init consumers may depend on slash_commands staying string-only.
Rejected: Replace slash_commands with objects | would risk breaking older SDK and desktop consumers.
Confidence: high
Scope-risk: moderate
Directive: Keep slash_commands as the compatibility name list unless all SDK consumers have migrated.

Resolve the remaining conflict in the Claude API request builder by preserving the contributor's Azure OpenAI response support while keeping main's explicit disabled-thinking handling and effort suppression.
Constraint: PR #21 was conflict-blocked against origin/main and maintainer edits are enabled on the fork branch
Rejected: Rebase the contributor branch | would rewrite a long external contribution history unnecessarily
Confidence: high

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.

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.

Not-tested: Full packaged Tauri desktop build.
Cuts the macOS .app from 435MB → 152MB (-65%) and the DMG from 113MB → 60MB
(-47%) by inlining src/server and src/entrypoints/cli into the bun-compiled
sidecar binaries instead of dynamic-importing them from disk at runtime.
Architectural change
====================
Before:
desktop/sidecars/server-launcher.ts → bun build --compile (≈57MB shell)
└─ at runtime: dynamic file:// import of <appRoot>/src/server/index.ts
which transitively requires ALL of src/ + the entire root node_modules/
to be shipped as Resource. tauri.conf.json copied 254M of node_modules
and 47M of src/ into Contents/Resources/app/ on every build.
After:
desktop/sidecars/server-launcher.ts → bun build --compile (≈65MB)
└─ uses `await import('../../src/server/index.ts')` with a literal
specifier so bun's bundler walks the whole graph statically and
inlines everything into the binary.
Same treatment for cli-launcher.ts → src/entrypoints/cli.tsx.
Resolver gymnastics
===================
This fork carries dozens of ant-internal feature() gated require/import
calls referencing modules that simply don't exist on disk
(cachedMicrocompact, devtools, proactive, coordinator, etc). Bun's resolver
walks the static dep graph BEFORE bun:bundle macro DCE, so even though
the dead branches never execute at runtime, they still fail to resolve
at compile time.
Two complementary mechanisms:
1. desktop/scripts/scan-missing-imports.ts walks src/, regex-greps every
relative import / require / type-import specifier, and writes a Proxy
noop stub for any target that doesn't exist on disk. Stubs are tagged
with "@generated stub from scan-missing-imports" for idempotency. Text
resources (.md / .txt / .json) get appropriate format-specific stubs.
Runs as a pre-step inside build:sidecars.
2. desktop/scripts/build-sidecars.ts adds an `external: [...]` list for
bare-package optional deps not in package.json (OTLP exporters,
@aws-sdk/*, @anthropic-ai/{bedrock,vertex,foundry,mcpb}-sdk,
@azure/identity, fflate, turndown, sharp, react-devtools-core).
These remain runtime imports, fail benignly when their gating env
var or feature flag is off.
Tauri side
==========
- desktop/src-tauri/tauri.conf.json: dropped all `resources` entries.
Was 7 entries totaling ≈301MB. Now `{}`.
- desktop/src-tauri/src/lib.rs `resolve_app_root` no longer calls
BaseDirectory::Resource (the app/ resource dir doesn't exist anymore);
instead returns the directory of the current sidecar exe. The launchers
still accept --app-root for backward compat with conversationService's
CLI subprocess spawn.
Optimisations
=============
- bun build now uses minify whitespace+identifiers+syntax. Saved another
≈16MB across both binaries (server: 72MB→65MB, cli: 75MB→66MB).
Bonus fix
=========
src/services/remoteManagedSettings/index.ts had a typo importing
'./securityCheck.jsx' instead of '.js'. Bun's runtime resolver tolerated
it; bun build didn't.
Verification
============
- Both binaries boot successfully in /tmp with no src/ or node_modules/
on disk. Verified `claude-cli --version` returns the build version,
`claude-cli --help` prints the full Commander spec, and claude-server
starts CronScheduler + listens on the requested port.
- bun test on src/ shows 358 pass / 45 fail / 2 errors vs main baseline
of 359 / 44 / 2 — net 0 new failures (1 different flake direction).
All 44 baseline failures pre-exist on main and are unrelated.
- Full DMG round-trip via build-macos-arm64.sh succeeds; new bundle
installs cleanly in /Volumes/.

Generated stub files (173 of them under src/) are committed for
reproducibility — the scanner is idempotent and will re-create them
identically on every build, but tracking them avoids dirty working trees
on first compile.

Bypass all three gating layers (compile-time feature flag, subscription
check, GrowthBook remote config) and replace Anthropic's private native
modules (@ant/computer-use-swift, @ant/computer-use-input) with a Python
bridge using pyautogui + mss + pyobjc. Works on any macOS with any
Anthropic-protocol compatible model.
