Mid-stream api_error/overloaded_error SSE events (e.g. a local provider such
as LM Studio rejecting a malformed tool_call) arrive inside the 200 SSE body,
bypassing withRetry — which only guards stream creation — so they were
surfaced as a terminal API error that ended the turn with no retry.
Add withStreamRetry around queryModel: when an attempt produced zero output
(no tool_use block completed, so query.ts never started a tool — safe w.r.t.
the double-tool-execution hazard, inc-4258), re-establish the stream and retry
up to CLAUDE_STREAM_TRANSIENT_RETRY_MAX times (default 2) before surfacing the
error. Covers both the streaming and non-streaming query wrappers; adds unit
tests for the retry loop and the transient-error classifier.
The configured request timeout (API_TIMEOUT_MS) only feeds the SDK client
timeout, which on a streaming request is cleared the moment response headers
arrive. Slow local/3P models return 200 headers fast but spend minutes
prefilling before the first SSE token, so that window was governed by the idle
watchdog (CLAUDE_STREAM_IDLE_TIMEOUT_MS, 240s) -- a separate env users cannot
configure. The configured timeout therefore never applied to slow prefill, so
raising it had no effect (#826, follow-up to #449).
Split the stream watchdog into phases: use a first-token budget (tied to the
user's request timeout via CLAUDE_STREAM_FIRST_TOKEN_TIMEOUT_MS) until the first
chunk arrives, then switch to the shorter mid-stream idle budget. The overall
max-duration cap (#766) still backstops trickling bodies; CLI defaults fall back
to prior behavior.
Third-party gateways can trickle content deltas (e.g. a large tool_use
input_json_delta) just under the idle-watchdog window and never send
message_stop. Each delta resets the idle timer, so the in-kernel watchdog
never fires and the request hangs forever — the desktop shows "running"
with slowly growing tokens and a permanently-pending trace span (#766).
Add an overall-duration watchdog (CLAUDE_STREAM_MAX_DURATION_MS) that is
armed once and never reset by incoming chunks; the desktop injects 600000ms
via buildChildEnv. Orthogonal to the idle watchdog: idle catches a fully
silent stream, this catches an endless trickle that never completes. CLI
default stays 0 (disabled) for backward compatibility.
Verified end-to-end by replaying the issue's real captured SSE against the
actual kernel: trickle hangs without the cap, aborts cleanly with it.
When an upstream request was aborted mid-stream (SDK client timeout,
stream idle watchdog, non-streaming fallback timeout, or user
cancellation), the trace fetch hook waited on a clone of the response
body that could hang forever, so the call never left "pending" in the
trace panel — exactly the silent stall that misled the #766 report.
- captureResponseTraceSnapshot reads the body with abort awareness:
reader.cancel() on abort keeps the partial body, with a 2s grace
backstop for runtimes where cancel cannot wake a hung read.
- The fetch hook now records an error-state call on abort with the
abort reason (e.g. the watchdog's stream idle timeout), duration,
partial response body, and an api_call_aborted event; non-abort
capture failures also record an error instead of inferring ok, and
pre-response fetch rejections carry an aborted flag.
- The trace detail panel shows an "Aborted" badge plus guidance for
aborted calls, and labels the new api_call_aborted phase in all
locales.

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.
The context usage indicator stayed at the pre-compact percentage (e.g.
100%) until the next API response arrived. Two stacked causes:
- The CLI anchors the displayed total to max(local estimate, last API
usage) so the meter never drops mid-turn — but preserved messages
(SM-compact / partial compact) still carried the pre-compact usage,
pinning the meter after compaction. buildPostCompactMessages now
zeroes token usage on preserved assistant copies, the established
stale placeholder that getCurrentUsage() skips, covering every
compaction path in one place. Originals are not mutated, so
transcript and cost accounting are unaffected.
- Right after compaction the CLI is often still busy, so the
indicator's refresh timed out ("Request timed out after 30s") and the
catch kept the stale context on screen with no later retry (auto
refresh is throttled to 10s and stops once the session goes idle).
compact_boundary now bumps a per-session compactCount; the indicator
force-refreshes on that nonce — bypassing the throttle and any
in-flight request that may still hold pre-compact data — and retries
once after 5s if the forced refresh fails.

timeline tree (draggable splitter, search/filter, keyboard nav) and a
section-flow detail panel (Response / Messages / System Prompt /
Tools / Parameters / Raw), collapse state persists across spans
- Render LLM requests/responses semantically: messages as role-colored
conversation with tool_use/tool_result pairing instead of raw JSON
dumps; Raw fallback via CodeViewer for legacy truncated records
- TraceList: row-style list with model chips, mono metrics, hover
actions; content-visibility rows (no virtualization, WebKit-safe)
- i18n synced across zh/en/jp/kr/zh-TW (+25/-55 keys)
Data & capture (server):

256KB -> 1MB; list API trims previews to keep polling light; new
GET /api/sessions/:id/trace/calls/:callId returns the full record

Electron desktop runs network-sensitive OpenAI OAuth token exchange in the sidecar process, so the sidecar now receives system proxy env derived from Electron's cross-platform proxy resolver and the OAuth token client uses the existing proxy fetch options. General manual proxy settings also document and preserve authenticated proxy URLs.
The macOS fullscreen black-screen path is addressed by avoiding native fullscreen Spaces for app fullscreen toggles and by leaving fullscreen before hiding or closing the window.
Constraint: Electron packaged apps may not inherit shell HTTPS_PROXY env when launched from Finder.

Introduce the Electron desktop shell alongside the existing React renderer and local Bun server boundary.

Synthetic API errors were carrying only English display text, so desktop chat could not distinguish our compatibility guidance from raw upstream failures and recovery logic depended on those English strings.
Add stable business error codes for media, PDF, request-size, prompt-length, and auto-mode errors.

Confidence: high
Scope-risk: moderate
Directive: Keep disabled-thinking effort suppression when changing provider request mapping
Tested: bun test tests/azureOpenAI.test.ts src/utils/__tests__/thinking.test.ts
Tested: bun run check:server
DeepSeek-compatible Anthropic endpoints reject requests that combine an explicit disabled-thinking block with an effort value. The desktop UI can create that shape when users disable thinking and keep medium effort selected, so the request builder now omits effort whenever it will send explicit disabled thinking.
Constraint: DeepSeek-compatible Anthropic endpoints reject disabled thinking with effort
Rejected: Only patch Desktop provider settings | hidden title and side request paths still share the request builder

Not-tested: Real DeepSeek API key live call
Desktop users can now disable thinking for new sessions, and Anthropic-compatible providers that opt in receive explicit disabled-thinking requests across main turns, side queries, and AI title generation.
Constraint: DeepSeek/Kimi/GLM Anthropic-compatible endpoints need a non-thinking path without scattering provider-specific logic through the CLI.
Rejected: Per-model if/else branches | centralized provider preset env keeps the native CLI surface smaller and easier to audit.

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/.
Bundle size summary
===================
metric baseline after P0 delta
Resources/app/ 301 MB 0 MB -301 MB
MacOS/claude-server 57 MB 65 MB +8 MB
MacOS/claude-cli 57 MB 66 MB +9 MB
MacOS/claude-code-desktop 18 MB 18 MB —
─────────────────────────────────────────────
.app total 435 MB 152 MB -283 MB (-65%)
.dmg 113 MB 60 MB -53 MB (-47%)
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.
