Jason 61e68d754c fix(proxy): inject only ANTHROPIC_API_KEY for managed-account Claude takeover
- Provider: add uses_managed_account_auth / is_github_copilot helpers
  to identify managed-account providers (GitHub Copilot / Codex OAuth)
- ProxyService: choose auth policy by provider type when taking over
  Claude Live config. Managed accounts drop token env keys and write
  only the ANTHROPIC_API_KEY placeholder; other providers keep the
  existing ANTHROPIC_AUTH_TOKEN fallback behavior
- Forwarder: add outbound guard that refuses to send the PROXY_MANAGED
  placeholder upstream to *.githubcopilot.com and chatgpt.com
  /backend-api/codex
- Add unit tests covering detection, injection, and the outbound guard

Jason b642ef0633 fix(failover): patch P1-P3 reliability gaps surfaced by team review
- Forwarder buffers non-streaming bodies and primes streaming first
  chunk before signaling success, so body timeouts and SSE first-chunk
  failures route through the circuit breaker instead of being recorded
  as success on response-header arrival
- Atomic enable-failover: switch to P1 before persisting the flag, and
  roll back auto-added queue entries when the switch is rejected
  (e.g. official providers)
- Hot-reload circuit breaker config on per-app proxy config change
  instead of waiting for a proxy restart
- FailoverToggle / FailoverQueueManager / AutoFailoverConfigPanel
  require proxy takeover for the active app; the backend command also
  rejects enabling when takeover is off
- ProviderHealthBadge consumes the backend is_healthy flag instead of
  hardcoding the 5-failure threshold

Cleanup:
- impl From<&AppProxyConfig> for CircuitBreakerConfig and use it from
  the command layer
- Collapse three identical TabsContent blocks into a single map

Jason 206125b4e3 fix(proxy): patch P0-P3 routing/lifecycle issues across forwarder paths
* stream_check: thread Result from get_auth_headers via map_err so
  the workspace builds again
* forwarder: scope rectifier / budget-rectifier flags per-provider so
  failover can still apply rectification on the next attempt
* forwarder: categorize before record_result; route NonRetryable and
  ClientAbort through release_permit_neutral so client-side failures
  don't pollute circuit breaker or DB health
* handler_context: parse Gemini model from uri.path() and strip both
  ?query and :action verb defensively in extract_gemini_model_from_path
* forwarder + response_processor + handlers: introduce
  ActiveConnectionGuard (RAII) so active_connections decrement covers
  the full streaming body lifetime, not just response headers
* claude_desktop_config: use sort_by_key to clear the clippy gate

Jason 85131d37d8 refactor(proxy): extract handle_rectifier_retry_failure helper
The signature (RECT-003) and budget (RECT-012) rectifier branches each
carried ~50 lines of identical "provider error -> record + continue /
client error -> release permit + return" handling. The only piece that
varied between them was a log label ("整流" vs "budget 整流").

Move the shared logic into RequestForwarder::handle_rectifier_retry_failure
that returns Option<ForwardError> — None means "continue to the next
provider", Some(err) means "terminal failure, return to the client".
Each call site shrinks from ~50 lines to ~17, drops one level of
indentation, and the two branches now provably cannot drift apart.

forwarder.rs nets ~40 lines smaller.

Jason 5d3d9067af feat(proxy): forward client HTTP method instead of hard-coding POST
The forwarder used to call client.post(&url) / http::Method::POST in
both the reqwest and hyper paths, and the Gemini route table only
registered POST /v1beta/*. As a result anything the Gemini SDK / CLI
sent as GET (models list, models/<id> info) hit a 404 at the router
and bypassed the local proxy's stats, rectifiers, and failover.

Thread the request method end-to-end:

- ProviderAdapter forwarder API now takes the http::Method by reference
  per attempt and dispatches client.request(method, &url) for reqwest
  and method.clone() for the hyper raw path.
- All five callers in handlers.rs (handle_messages_for_app for Claude /
  Claude Desktop, handle_chat_completions, handle_responses,
  handle_responses_compact, handle_gemini) pull the method out of the
  incoming axum::extract::Request and pass it on.
- handle_gemini tolerates an empty body (GET endpoints have none) and
  the forwarder skips serializing / sending a body for GET / HEAD —
  attaching JSON to a GET makes Gemini reject the request.
- server.rs swaps the Gemini routes to any(handle_gemini) so the same
  handler handles GET / POST / PUT / DELETE, and adds /gemini/v1/*
  for the GA path version.

Jason f2ae9823cb fix(proxy): move client-request counters out of per-attempt loop
Three statistics-shape issues fixed together so the dashboard reflects
client requests, not provider attempts:

1. active_connections never moved off zero — the field had no caller in
   the entire crate. Wrap forward_with_retry into a thin entry point
   that saturating_add(1) on enter and saturating_sub(1) on exit; every
   inner return path is covered automatically.

2. total_requests counted attempts, not requests. A single client call
   that failed over P1 -> P2 -> success was recorded as
   total=2 / success=1 -> 50% success rate. Move the increment and the
   last_request_at refresh into the wrapper so they fire once per
   client request regardless of how many providers were tried.

3. current_provider / current_provider_id stay inside the inner loop
   because they are intentionally per-attempt ("what am I trying right
   now?") — moving them would break the live-failover indicator.

Refactor: split forward_with_retry into a public wrapper + private
forward_with_retry_inner. Every existing `return Err(...)` inside inner
remains correct because the wrapper always runs the decrement on its
return.

Jason b06e0fa538 fix(proxy): wire AppProxyConfig.max_retries into request forwarder
The UI has exposed "请求失败时的重试次数 (0-10, default 3)" since the
auto-failover panel was added, but the value was silently dropped —
RequestForwarder never received it and the per-provider loop walked the
whole list regardless. From the user's perspective the setting was
inert.

Thread AppProxyConfig.max_retries through create_forwarder into
RequestForwarder, derive max_attempts = max_retries + 1 (so max_retries=0
matches the UI copy "0 retries" = single attempt), and break the loop
once attempts hit the cap. The check is placed before the circuit
breaker allow-permit so an over-cap iteration does not waste a HalfOpen
probe slot.

When auto-failover is disabled we also force max_retries to 0, mirroring
how timeouts already bypass in that mode — "no failover" should mean
"one provider, one try", not "limited retries against the same list".

Jason cb4ecd3951 fix(proxy): refine failover decisions in forwarder
Two related changes to make per-provider failover behave correctly.

1. Bucket UpstreamError by status code in categorize_proxy_error.

   The old "every UpstreamError is Retryable" rule meant a malformed
   client request (400 / 422) would be replayed against every provider
   in the queue: errors amplified N-fold, the circuit breaker accrued
   unwarranted failure counts, and quota was burned. Now
   400 / 405 / 406 / 413 / 414 / 415 / 422 / 501 are NonRetryable since
   the request itself is wrong and no provider will accept it.
   401 / 403 / 404 / 408 / 409 / 429 / 451 and all 5xx remain Retryable
   because the next provider may carry a different key, quota, region,
   or model mapping.

2. Make the rectifier-retry path participate in failover.

   Both the signature (RECT-003) and budget (RECT-012) rectifier branches
   used to "return Err(...)" after the retry failed, short-circuiting the
   per-provider loop. A provider-side failure (5xx / Timeout /
   ForwardFailed) now records the circuit breaker, accumulates into
   last_error / last_provider, and "continue"s to the next provider —
   matching the normal Retryable arm. Client-side failures still return
   immediately since a different provider cannot fix a malformed payload.

Jason c9a6afc0b7 fix(proxy): return Result from get_auth_headers to avoid panic on bad credentials
User-pasted API keys can contain control chars or CR/LF that make
HeaderValue::from_str return Err; the previous unwrap inside every
adapter turned such input into a process-wide panic instead of a request
error. The trait now returns Result<_, ProxyError>; Claude/Codex/Gemini
impls propagate ProxyError::AuthError so the client sees a 401 with the
underlying parse error instead of a crash. Adds a regression test that
pastes a CRLF-containing key and asserts AuthError.

Jason 4b57f7e113 feat(claude-code): role-based model mapping with display names and 1M flag
- Replace the four flat env inputs with a Sonnet/Opus/Haiku role table.
  Each row exposes ANTHROPIC_DEFAULT_*_MODEL plus a new display name
  field ANTHROPIC_DEFAULT_*_MODEL_NAME, and Sonnet/Opus gain a
  "Declare 1M" checkbox that toggles the [1M] suffix.
- Strip the [1M] context-capability marker before forwarding non-Copilot
  requests upstream. Copilot keeps its existing [1m]->-1m normalization.
- Claude Desktop import now consumes ANTHROPIC_DEFAULT_*_MODEL_NAME as
  label_override, closing the Claude Code -> Claude Desktop displayName
  pipeline; add_route's merge logic is shared between hashmap branches.
- Unify the [1M] marker as ONE_M_CONTEXT_MARKER across
  claude_desktop_config and proxy::model_mapper; rename the strip
  helper to strip_one_m_suffix_for_upstream.
- Collapse useModelState's seven duplicated useState initializers and
  the useEffect parse block into a single parseModelsFromConfig call.
- Add tests/hooks/useModelState.test.tsx and a Claude Desktop import
  test covering Kimi K2 -> label_override. i18n (en/ja/zh) updated.

Jason 4b384dfe55 perf(proxy): trim per-request hot-path work and db wait
- Guard debug body serialization with `log::log_enabled!`; previously
  serialized the filtered body to a throwaway String on every forward,
  even with debug logging off.
- Skip SSE parse + UTF-8 buffer loop when no usage collector and debug
  is off; the per-chunk `serde_json::from_str::<Value>` ran even in
  pure passthrough mode.
- Add cheap per-app SSE event pre-filter (string `contains`) so usage
  collectors only parse events that could contain usage (e.g. Claude
  `message_start` / `message_delta`).
- Skip non-streaming response body JSON parse when usage logging is
  disabled.
- Move `ProviderRouter::record_result` off the success response path
  via `tokio::spawn` for non-HalfOpen state; that call internally does
  `get_proxy_config_for_app` + `update_provider_health`, two SQLite
  ops that previously blocked TTFB.

Also: dedupe `usage_logging_enabled` (was duplicated in handlers.rs)
and merge `SseUsageCollector::{new, new_filtered}` into a single
constructor that takes `Option<StreamUsageEventFilter>`.

Jason 00a789e7a3 fix(proxy): improve cache hit rate for Codex/Responses requests
prompt_cache_key was falling back to provider.id when the client did not
supply a session, which collapsed every conversation onto a single key
and defeated upstream prefix caching. Only emit the key when a real
client-provided session/thread identity is available; otherwise let the
upstream use its default matching behaviour.

Additional fixes that affect cache stability:
- Canonicalise (sort) JSON keys in outgoing request bodies and in
  tool_call arguments / tool_result content so semantically identical
  requests produce identical byte sequences for upstream prefix caches.
- Exempt JSON Schema property maps (properties, patternProperties,
  definitions, \$defs) from the underscore-prefix filter so user-defined
  schema keys like _id and _meta survive.
- Add a [CacheTrace] debug log with stable hashes for instructions,
  tools, input and include to help diagnose cache misses.
- Thread session_id into the usage logger for request correlation.

Jason 292c117509 chore(backend): satisfy cargo fmt and clippy --all-targets
- Apply rustfmt diffs in claude_desktop_config.rs
- Allow needless_return on current_platform_paths (cfg-mirrored arms)
- Allow too_many_arguments on RequestForwarder::forward
- Replace `let mut + reassign` with struct literals in tests
  (settings, backup, provider, response_processor)
- Use Path::new instead of PathBuf::from to fix cmp_owned in misc tests
- Replace 3.14 with 3.5 in config test to avoid approx_constant lint

Jason 8b3ad9caf9 feat(claude-desktop): add 3P provider switching with proxy gateway
Adds a new ClaudeDesktop AppType that writes Claude Desktop's third-party
inference profile under configLibrary/, sharing _meta.json with other
launchers (Ollama-compatible) so cc-switch can coexist with them.

Two switch modes:
- direct: provider already exposes claude-* / anthropic/claude-* model
  ids on Anthropic Messages, Claude Desktop connects to it directly.
- proxy: cc-switch's local proxy acts as the inference gateway,
  presenting only claude-* route names to Claude Desktop and mapping
  them to real upstream models. Required after Anthropic restricted
  Claude Desktop to claude-family ids.

Backend:
- New module claude_desktop_config with snapshot/rollback, official seed
  bypass, /claude-desktop/v1/{models,messages} routes, and a single
  source of truth for default proxy routes.
- Gateway token persisted in SQLite, validated on every proxied request.
- get_claude_desktop_status surfaces drift signals (stale models,
  missing routes, proxy stopped, base URL mismatch, missing token).

Frontend:
- Slim ClaudeDesktopProviderForm independent from ProviderForm,
  controlled by a top-level appId guard.
- ProviderList banner consumes the status query (5s polling) and
  renders actionable diagnostics.
- ClaudeDesktopRouteToggle in the header to start/stop the local
  gateway without touching takeover state.
- Three-locale i18n synchronised.

Jason e15bfbfe7a fix(proxy): reuse pooled HTTPS connections for non-Anthropic backends
The hyper raw-write path preserves original header casing but rebuilds
TCP+TLS on every request — there is no connection pool — which was the
root cause of slow reverse-proxy throughput.

Only Anthropic-native requests actually need exact header-case
preservation. Route OpenAI/Copilot/Codex/Gemini/codex_oauth requests
through the pooled reqwest client (pool_max_idle_per_host=10,
tcp_keepalive=60s) instead, so warm connections get reused.

Streaming requests get a precise first-byte timeout via
tokio::time::timeout around reqwest's send() (which resolves on
response headers), with the body phase handed off to response_processor.
The streaming-detection helper now also covers Gemini SSE endpoints
and Accept: text/event-stream, not just body.stream.

Jason fcd83ee30d fix(copilot): resolve Claude model IDs against live /models list
Copilot upstream returns model_not_supported when the client sends
dash-form Claude IDs (claude-sonnet-4-6, claude-sonnet-4-6[1m]) while
/models only accepts dot form (claude-sonnet-4.6, -1m suffix).

- Add copilot_model_map: syntax normalize (dash->dot, [1m]->-1m) plus
  live /models exact match and family-version fallback, reusing the
  existing 5 min auth cache. Returns None when the whole family is
  absent so upstream surfaces an explicit error instead of silently
  switching families.
- Wire into forwarder Copilot hook; runs before anthropic_to_openai
  conversion.
- Default Opus slot in the Copilot preset maps to Sonnet 4.6: Pro
  dropped all Opus on 2026-04-20 and Pro+ bills Opus 4.7 at 7.5x.
  Users who want real Opus can switch manually in the UI.

lif 444c123ad0 [codex] Stabilize Codex OAuth cache routing (#2218)
* Stabilize Codex OAuth cache routing

Codex OAuth-backed Claude proxy requests now reuse a client-provided session identity for prompt cache routing and send Codex-like session headers when that identity exists. Generated proxy UUIDs are intentionally excluded so they do not fragment cache locality.\n\nThe same path exposed two runtime issues during validation: rustls needed an explicit process crypto provider, and Codex OAuth can return Responses SSE even when the original Claude request is non-streaming. Those are handled so cache-routed requests can complete instead of panicking or being parsed as JSON.\n\nConstraint: Official Codex uses conversation identity and Responses session headers for prompt cache routing.\nRejected: Always use generated proxy session IDs | generated IDs change per request and reduce cache reuse.\nConfidence: medium\nScope-risk: moderate\nDirective: Do not remove the client-provided-session guard unless generated session IDs become stable per conversation.\nTested: cargo test codex_oauth\nTested: Local dev app health check on 127.0.0.1:15721\nTested: Local proxy logs showed cache_read_tokens after restart\nNot-tested: Full cargo test without local cc-switch port conflict\nRelated: #2217

* feat(proxy): aggregate forced Codex OAuth SSE into JSON for non-streaming clients

Narrow override on top of #2235's streaming fallback.

Codex OAuth always forces upstream openai_responses into SSE, even
when the original Claude request is stream:false. #2235 handles this
by routing such responses through the streaming transform so the
client receives text/event-stream — that avoids the 422 that JSON
parsing would produce, and it also protects any other provider that
unexpectedly returns SSE (the response.is_sse() guard).

But for Claude SDK callers that sent stream:false, returning SSE
still violates the Anthropic non-streaming contract. This commit
adds an override on exactly one combination — non-streaming client
+ codex_oauth + openai_responses — to aggregate the upstream
Responses SSE into a synthetic Responses JSON and then run the
regular responses_to_anthropic non-streaming transform. All other
paths, including the generic response.is_sse() fallback, remain
on the streaming path from #2235.

The aggregator reuses proxy::sse::take_sse_block / strip_sse_field,
which support both \n\n and \r\n\r\n delimiters; a hand-rolled
split("\n\n") would silently fail on real HTTPS upstreams.

Tests cover the happy path, CRLF delimiters, response.failed
errors, and the missing response.completed defensive branch.

Jason 63aa310576 feat(copilot): strip thinking blocks before forwarding to save premium quota
Copilot routes through OpenAI-compatible endpoints that reject Anthropic's
thinking and redacted_thinking blocks. Previously the request would fail
upstream, burning one premium interaction, and only then trigger
thinking_rectifier to retry. This adds a proactive strip_thinking_blocks
pass in the Copilot optimization pipeline (step 3.5, after tool_result
merging). Signature fields and top-level thinking are left alone — those
are the reactive rectifier's job on the error path.

Also fixes a default-value inconsistency where CopilotOptimizerConfig's
Default impl used "gpt-4o-mini" while the serde default function returned
"gpt-5-mini" (aligned to gpt-5-mini, matching the reference implementation).

Aligned with yuegongzi/copilot-api's /v1/messages handler behavior.

Dex Miller 03a0f9661b feat(proxy): Gemini Native API proxy integration (#1918)
* refactor(proxy): extract take_sse_block helper with CRLF delimiter support

Replace inline `buffer.find("\n\n")` SSE splitting logic across streaming,
streaming_responses, response_handler, and response_processor with a shared
`take_sse_block` function that handles both `\n\n` and `\r\n\r\n` delimiters.

* feat(proxy): add Gemini Native URL builder and full-URL resolver

Introduce gemini_url module that normalizes legacy Gemini/OpenAI-compatible
base URLs into canonical models/*:generateContent endpoints. Supports both
structured Gemini URLs (auto-normalized) and opaque relay URLs (pass-through
with query params only).

* feat(proxy): add Gemini Native schema, shadow store, transform, and streaming

- gemini_schema: Gemini generateContent request/response type definitions
- gemini_shadow: session-scoped shadow store for thinking signature and
  tool-call state replay across streaming chunks
- transform_gemini: bidirectional Anthropic Messages ↔ Gemini Native
  request/response conversion with thinking block and tool-use support
- streaming_gemini: Gemini SSE → Anthropic SSE streaming adapter with
  incremental thinking/text/tool_use delta emission

* feat(proxy): wire Gemini Native format into proxy core and Claude adapter

Integrate gemini_native api_format throughout the proxy pipeline:
- ClaudeAdapter: detect Gemini provider type, Google/GoogleOAuth auth
  strategies, and suppress Anthropic-specific headers for Gemini targets
- Forwarder: Gemini URL resolution, shadow store threading, endpoint
  rewriting to models/*:generateContent with stream/non-stream variants
- Handlers: route Gemini streaming through streaming_gemini adapter and
  non-streaming through transform_gemini converter
- Server/State: add GeminiShadowStore to shared ProxyState
- StreamCheck: support gemini_native health check with proper auth headers

* feat(ui): add Gemini Native provider preset and api format option

- Add gemini_native to ClaudeApiFormat type and ProviderMeta.apiFormat
- Add "Gemini Native" provider preset with default Google AI endpoints
- Show Gemini-specific endpoint hints and full-URL mode guidance
- Add gemini_native option to API format selector in ClaudeFormFields
- Add i18n strings for zh/en/ja

* feat(proxy): add Gemini Native tool argument rectification

* feat(proxy): update Gemini streaming and transformation logic

* fix(proxy): align shadow turns to tail on client history truncation

* fix: revert unrelated cache_key change in claude proxy transform

Restore .unwrap_or(&provider.id) fallback for cache_key to match main
branch behavior. Only gemini_native related changes should be in this branch.

* Prevent Gemini review regressions in streaming and tool rectification

PR #1918 review feedback exposed two correctness issues in the Gemini Native adapter path. Gemini SSE buffering was still using lossy UTF-8 decoding, which could corrupt split multibyte payloads and drop streamed output. Tool arg rectification also removed top-level parameters eagerly, which broke tools that legitimately define a parameters field.

This change moves Gemini SSE buffering onto the existing append_utf8_safe path and makes parameters flattening conditional on the schema actually expecting nested extraction. The old Skill rectification path stays intact, and new regression tests cover both the preserved parameters case and UTF-8-split JSON payloads.

Constraint: Existing PR #1918 review feedback must be fixed without staging unrelated local docs and artifact files
Rejected: Keep String::from_utf8_lossy in Gemini SSE buffering | corrupts split multibyte payloads and can drop JSON chunks
Rejected: Always preserve the parameters wrapper | regresses the existing nested-parameters rectification path for Skill-style tools
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep Gemini SSE buffering on the UTF-8-safe accumulator path and only unwrap parameters when the target schema does not declare it as a legitimate field

Not-tested: Full src-tauri test suite; live end-to-end Gemini relay traffic against upstream services

* Keep Gemini tool replay stable across Claude request boundaries

Claude Code follow-up requests were still falling back to locally reconstructed functionCall parts, which dropped Gemini thought signatures and triggered INVALID_ARGUMENT errors from the official Gemini API. The replay path needed to survive real Claude request boundaries, not just idealized in-process test flows.

This change makes Claude requests reuse X-Claude-Code-Session-Id as the shadow session key, records streamed Gemini tool turns before tool_use events are fully drained, and matches assistant tool_use turns to shadow state by tool_use id and normalized tool name before positional fallback. Together these fixes keep thoughtSignature-bearing Gemini tool calls available for the next request in the loop.

Constraint: Claude Code sends a stable X-Claude-Code-Session-Id header while metadata.session_id may be absent on follow-up requests
Rejected: Rely on metadata-only Claude session extraction | generated fresh session ids and broke cross-request shadow replay
Rejected: Record Gemini shadow only after streaming completes | loses the race when the client sends the next request immediately after tool_use
Confidence: high
Scope-risk: narrow

* style: apply cargo fmt to pass Backend Checks CI

Wrap prompt_cache_key chained call across lines per rustfmt default
formatting. Pure formatting change, no behavior difference.

* fix(proxy/gemini): synthesize unique ids for no-id tool calls + enforce object params schema

P1 — Parallel tool calls without Gemini-assigned ids no longer collapse.
Gemini 2.x native parallel `functionCall` entries may omit the `id` field.
The previous `merge_tool_call_snapshots` fell back to matching by `name`,
which silently merged two parallel calls to the same function into one
entry — dropping the first call's args. The non-streaming path and shadow
store further bottlenecked on empty-string ids: multiple `tool_use` blocks
shared the same id, and `tool_name_by_id.get("")` could only return one
mapping, causing later `tool_result` round-trips to fail with
`Unable to resolve Gemini functionResponse.name` or bind to the wrong tool.

Fix: introduce `synthesize_tool_call_id()` producing `gemini_synth_<uuid>`.
Both streaming and non-streaming response paths now guarantee every
Anthropic-visible tool_use carries a unique id. `merge_tool_call_snapshots`
matches by id first, falling back to the `parts` array position (for the
cumulative-streaming case) while preserving the synthesized id across
chunks. `convert_message_content_to_parts` detects the synthetic prefix
and strips the id from outbound `functionCall`/`functionResponse` so the
internal identifier never leaks upstream. `shadow_parts` performs the
same strip when replaying a recorded assistant turn.

P2 — Vertex AI rejects empty `parameters` schemas. When an Anthropic tool
arrives with missing or empty `input_schema`, the proxy used to emit
`"parameters": {}` (no `type`), which fails Vertex AI validation with
`functionDeclaration parameters schema should be of type OBJECT`.
Contrary to the automated-review suggestion, the fix is not to omit
`parameters` (that too is rejected) but to normalize to the canonical
empty-object form `{type: "object", properties: {}}`.
Refs: google-gemini/generative-ai-python#423, BerriAI/litellm#5055.

Fix: new `ensure_object_schema` helper in `gemini_schema` promotes
missing `type` to `"object"` and adds empty `properties` when absent,
while leaving atomic (non-object) schemas untouched.

Tests: seven new regressions covering parallel no-id calls, cumulative
chunk id reuse, synthetic-id round-trip both directions, shadow replay
id stripping, and the three Vertex-AI schema shapes.

The two existing wrapper functions (`gemini_to_anthropic` and
`gemini_to_anthropic_with_shadow`) gain `#[allow(dead_code)]` to clear
a pre-existing clippy -D warnings failure — they are part of the public
transform API surface and intentionally kept for future callers.

* fix(proxy/gemini): narrow URL normalization + guard empty OAuth access_token

P2a — Preserve opaque relay URLs that contain `/v1/models/` prefixes.

`should_normalize_gemini_full_url` previously flagged any full URL whose
path merely contained `/v1beta/models/` or `/v1/models/` as a structured
Gemini endpoint, forcing rewrite to `.../v1beta/models/{model}:method`.
This silently dropped legitimate relay route segments (e.g.
`https://relay.example/v1/models/invoke` → `.../v1beta/models/...:generateContent`,
losing `/invoke`) and sent traffic to the wrong upstream path.

Replace the bare `contains(...)` checks with
`matches_structured_gemini_models_path`, which requires the
`/models/` segment to be followed by a canonical Gemini method call
(`*:generateContent` or `*:streamGenerateContent`). The
`matches_bare_gemini_models_path` helper is generalized (and renamed) to
handle both `/v1beta/models/` and `/v1/models/` alongside the original
bare `/models/` shape.

P2b — Reject empty Gemini OAuth access_tokens before they reach the
bearer header.

`GeminiAdapter::parse_oauth_credentials` accepts refresh-token-only JSON
(and surfaces `{"access_token": "", ...}` for expired credentials) with
`access_token` defaulting to `""`. The Claude adapter's GeminiCli branch
then called `AuthInfo::with_access_token(key, creds.access_token)`
unconditionally, so the bearer-header builder at
`AuthStrategy::GoogleOAuth` resolved to `Authorization: Bearer ` — a
deterministic 401 from upstream.

CC Switch does not currently exchange the refresh_token for a fresh
access_token (`OAuthCredentials::needs_refresh` / `can_refresh` are
annotated `#[allow(dead_code)]`). Until that exists, only attach
`access_token` when it is non-empty; fall back to plain GoogleOAuth
strategy with the raw key and log a warn pointing users at
`~/.gemini/oauth_creds.json` so the failure mode is observable.

Tests:
- gemini_url.rs: three new regressions — opaque `/v1/models/invoke`,
  opaque `/v1beta/models/route`, and the positive counter-case where a
  structured `/v1/models/...:generateContent` path still normalizes.
- claude.rs: three new `test_extract_auth_gemini_cli_*` tests covering
  refresh-only JSON, empty-string access_token JSON, and the valid-JSON
  pass-through.

All 839 lib tests pass; cargo fmt + clippy -D warnings clean.

Addresses Codex review P2 findings on #1918.

* fix(proxy/gemini): treat empty-string functionCall id as missing in streaming path

Follow-up to the earlier P1 fix: some Gemini relays serialize an absent
functionCall id as `"id": ""` instead of omitting the field. The
non-streaming `extract_tool_call_meta` already filters these via
`.filter(|s| !s.is_empty())`, but the streaming counterpart
`extract_tool_calls` passed the empty string straight through
`function_call.get("id").and_then(|v| v.as_str())` into
`GeminiToolCallMeta::new`, producing a `Some("")` id.

Downstream, `merge_tool_call_snapshots` would then match two parallel
no-id calls against each other on their shared empty-string id,
collapsing them into a single snapshot (silent data loss for the first
call) and emitting an Anthropic `tool_use.id: ""` that breaks tool_result
correlation on the Claude Code client.

Fix:
- `extract_tool_calls`: apply the same `filter(|s| !s.is_empty())` guard
  used in the non-streaming path so empty strings become `None` before
  reaching the shadow meta.
- `merge_tool_call_snapshots`: defensively collapse any incoming
  `Some("")` to `None` up front — keeps the "missing vs present" invariant
  local to the merge step for future callers that might build
  `GeminiToolCallMeta` by hand.

Tests (2 new, both in streaming_gemini):
- `parallel_empty_string_id_calls_are_treated_as_missing_and_preserved`
  covers two parallel calls with explicit `"id": ""` — asserts both
  surface, no empty tool_use id leaks, and each gets a unique
  `gemini_synth_` id.
- `single_empty_string_id_tool_call_gets_synthesized_id` covers the
  non-parallel degraded-relay case.

All 841 lib tests pass; cargo fmt + clippy -D warnings clean.

Addresses Codex follow-up P1 on #1918.

* fix(proxy/gemini): gate generic REST path suffixes behind Google host whitelist

`should_normalize_gemini_full_url` previously treated any full URL whose
path ends with `/v1`, `/v1/models`, `/models`, `/v1/openai`, or `/openai`
as a structured Gemini endpoint and rewrote it to
`/v1beta/models/{model}:generateContent`. These are ubiquitous REST
conventions — opaque relays such as `https://relay.example/custom/v1`
legitimately use them for fixed endpoints — so the rewrite silently
routed traffic to the wrong upstream path.

Split the predicate into two layers:

- **Unconditional**: `matches_structured_gemini_models_path` (i.e. a
  `/models/...:generateContent` method call anywhere in the path), the
  Google-specific `/v1beta*` family, and the deep OpenAI-compat paths
  (`/v1beta/openai/chat/completions`, `/openai/chat/completions`, and
  their `responses` siblings). These remain host-agnostic because the
  path grammar itself is Gemini-specific.
- **Google-host gated**: `/v1`, `/v1/models`, `/models`, `/v1/openai`,
  `/openai`. Only normalized when the host is one of
  `generativelanguage.googleapis.com`, `aiplatform.googleapis.com`, or a
  real `*-aiplatform.googleapis.com` Vertex regional endpoint. The match
  is exact/suffix (not `contains`), so lookalike hosts like
  `aiplatform.example.com` are correctly treated as opaque relays.

Tests (8 new in `gemini_url::tests`):
- Four opaque-relay cases: `/custom/v1`, `/custom/models`,
  `/custom/v1/models`, `/custom/openai` — all preserved as-is.
- Three Google-host counter-cases: `/v1`, `/models`, and
  `us-central1-aiplatform.googleapis.com/v1` still normalize.
- One lookalike safety case: `aiplatform.example.com/v1` is NOT
  treated as Google.

All 849 lib tests pass; cargo fmt + clippy -D warnings clean.

* fix(proxy/gemini): align shadow id with client-visible id in non-streaming path

When Gemini returns a `functionCall` without an id (common in 2.x
parallel calls), `gemini_to_anthropic_with_shadow_and_hints` previously
generated TWO independent synthesized UUIDs:

  1. Line 186-197 — synthesized id `A` used for the Anthropic-visible
     `content[tool_use].id` returned to the client.
  2. Line 850-881 — `extract_tool_call_meta` independently synthesized
     id `B ≠ A`, which populated `shadow_turn.tool_calls[i].id`.

`shadow_content` (line 225-228, cloned from `rectified_parts`) retained
the original missing/empty id. Result: the client sees id `A`, the
shadow store holds id `B`.

On the next turn, `convert_messages_to_contents` builds
`tool_name_by_id` from `build_tool_name_map_from_shadow_turns`, which
uses `tool_calls[i].id` — so the map contains `B → name` but not
`A → name`. When the client sends back `tool_result(tool_use_id=A)`,
resolution fails with:

  Unable to resolve Gemini functionResponse.name for tool_use_id `A`

This affects both truncated histories (client sends only the
tool_result) and full histories (shadow-replay branch at line 342-354
skips `convert_message_content_to_parts`, so the assistant tool_use
block never registers id `A` itself).

Fix: make `rectified_parts` the single source of truth. After
`rectify_tool_call_parts`, run a pre-pass that writes
`synthesize_tool_call_id()` back into any `functionCall` that lacks a
non-empty id. All three readers — the content builder (186-197), the
shadow_content clone (225-228), and `extract_tool_call_meta` — then
observe the same id. `shadow_parts()` already strips synthesized ids on
replay (line 616-628), so the internal identifier never leaks to
Gemini upstream.

This mirrors the streaming path, which already has single-source-of-
truth semantics via `tool_call_snapshots` in `streaming_gemini.rs` —
no change needed there.

Tests (5 new in `transform_gemini::tests`):
- `non_stream_shadow_id_matches_client_visible_id`: asserts
  `response.content[0].id == shadow.tool_calls[0].id ==
  shadow.assistant_content.parts[0].functionCall.id`.
- `non_stream_missing_id_scenario_a_truncated_history_resolves`: turn 2
  sends only `[tool_result(id=A)]`; resolution must succeed.
- `non_stream_missing_id_scenario_b_full_history_replay_resolves`: turn 2
  sends `[assistant(tool_use=A), tool_result(A)]`; shadow-replay branch
  strips the synth id from outgoing `functionCall` while still
  resolving the subsequent `tool_result`.
- `non_stream_preserves_original_gemini_id_when_present`: regression —
  genuine Gemini ids flow through unchanged.
- `non_stream_synthesized_id_not_leaked_to_gemini_via_shadow_replay`:
  defensive — shadow-replay path must strip synth ids from both
  `functionCall.id` and `functionResponse.id`.

All 854 lib tests pass; cargo fmt + clippy -D warnings clean.

Addresses Codex follow-up P1 on #1918.

* refactor(proxy/gemini): share build_anthropic_usage between stream and non-stream paths

`streaming_gemini::anthropic_usage_from_gemini` and
`transform_gemini::build_anthropic_usage` were byte-for-byte identical
(32 lines each) — both converting Gemini `usageMetadata` into the
Anthropic `usage` shape including `cache_read_input_tokens` mapping.

Promote the non-streaming version to `pub(crate)` and reuse it from the
streaming SSE converter. Removes ~30 lines of duplication and guarantees
the two paths cannot drift apart.

No behavioral change; all 854 lib tests pass; cargo fmt + clippy -D
warnings clean.

* fix(proxy/gemini): gate /v1beta behind Google host + normalize models/ model id prefix

Two related P2 corrections to the Gemini Native URL surface, both
folding into the existing Google-host-whitelist architecture.

## P2a — `/v1beta` suffix should not unconditionally trigger rewrite

`should_normalize_gemini_full_url` placed `/v1beta` and `/v1beta/models`
in the unconditional layer on the reasoning that `/v1beta` is
Google-specific. In practice an opaque relay fronting a non-Gemini
service at `https://relay.example/custom/v1beta` would still be
silently rewritten to `/v1beta/models/{model}:generateContent`,
breaking the deployment.

Move `/v1beta`, `/v1beta/models`, and `/v1beta/openai` into the
Google-host gated layer alongside `/v1`, `/models`, and friends. The
unconditional layer now only accepts paths whose grammar is
intrinsically Gemini — `/models/...:generateContent` method calls and
the deep OpenAI-compat endpoints like `/openai/chat/completions` and
`/openai/responses`. Pasted AI-Studio URLs such as
`https://generativelanguage.googleapis.com/v1beta` still normalize
because the host matches the whitelist.

## P2b — `model: "models/gemini-2.5-pro"` produced doubled path prefix

Gemini SDKs (and the official `list_models` response) commonly surface
model ids in resource-name form `models/gemini-2.5-pro`. Raw
interpolation into `format!("/v1beta/models/{model}:...")` produced
`/v1beta/models/models/gemini-2.5-pro:streamGenerateContent` which
upstream rejects — yielding false-negative health checks for otherwise
valid provider configs.

Introduce `normalize_gemini_model_id(&str) -> &str` in `gemini_url`
as the single source of truth: strips an optional leading `/` then an
optional `models/` prefix, leaving bare ids untouched. Apply in the
three call sites that build a Gemini method URL:
- `services/stream_check.rs::resolve_claude_stream_url` (unified path)
- `services/stream_check.rs::check_gemini_stream` (Gemini-only path)
- `proxy/forwarder.rs::rewrite_claude_transform_endpoint` (production)

Tests (9 new):
- `gemini_url`: 3 regressions for opaque vs Google-host `/v1beta*`
  handling + 5 unit tests pinning `normalize_gemini_model_id` behavior
  (strip prefix, leave bare id, preserve nested slashes past the one
  stripped prefix, tolerate leading slash, pass through empty input).
- `stream_check`: one end-to-end regression confirming
  `models/gemini-2.5-pro` collapses to the expected single-prefix URL.
- `forwarder`: one end-to-end regression on the production rewrite
  path.

All 864 lib tests pass; cargo fmt + clippy -D warnings clean.

* fix(proxy/gemini): trim API key before provider-type detection and OAuth parsing

Leading whitespace on a copied oauth_creds.json (e.g. trailing newline
when the user copies the file content as-is) would slip past the
`starts_with("ya29.") || starts_with('{')` prefix check in
`ClaudeAdapter::provider_type`, causing the provider to be misclassified
as raw-API-key Gemini and fall back to `x-goog-api-key` with the raw
JSON as the key — which upstream rejects with 401.

The frontend's `handleApiKeyChange` already trims on keystrokes but
deep-link imports, the JSON editor, and live-config backfill all bypass
that path. Trim at every backend extraction point so the coverage is
uniform:

- `ClaudeAdapter::extract_key` (5 env / fallback branches) gets
  `.map(str::trim)` before `.filter(|s| !s.is_empty())` so that
  whitespace-only values are also treated as missing.
- `GeminiAdapter::extract_key_raw` gets the same chain (including
  the `.filter` it was missing before).
- `GeminiAdapter::parse_oauth_credentials` gets a defensive
  `let key = key.trim();` at the entry as a belt-and-suspenders guard.

Adds two regression tests covering JSON and bare `ya29.` keys with
leading newline/space.

* fix(proxy/gemini): gate generic REST suffix stripping behind Google host in non-full-URL mode

`build_gemini_native_url` unconditionally stripped `/v1`, `/v1beta`,
`/models`, and `/openai` suffixes from the base path regardless of
host. This worked for Google's own endpoints but silently rewrote
third-party relay URLs like `https://relay.example/custom/v1` to
`.../custom/v1beta/models/...`, breaking any relay that mounts its
Gemini-compatible namespace under a versioned prefix.

The result was also asymmetric with the previously-fixed full-URL
branch: toggling the "full URL" switch changed the outbound URL for
the same base_url, which is exactly the kind of invisible behavior
that makes debugging proxy deployments painful.

Align `normalize_gemini_base_path` with
`should_normalize_gemini_full_url`'s layered model:

- Unconditional: `/models/...:method` structured paths and deep
  OpenAI-compat endpoints (`/openai/chat/completions`,
  `/openai/responses` and their versioned variants) — these are
  unambiguous Gemini-specific grammar on any host.
- Google-host gated: generic `/v1`, `/v1beta`, `/models`, `/openai`
  suffixes only get stripped on `generativelanguage.googleapis.com`,
  `aiplatform.googleapis.com`, or `*-aiplatform.googleapis.com`.
  Other hosts preserve the prefix verbatim so relays keep their
  intended routing.

Adds seven regression tests for the non-full-URL flow: opaque relay
preservation (v1 / v1beta / models / openai suffix variants), Google
host normalization (counter-case), and boundary cases (structured
method path and deep OpenAI-compat endpoint stripped regardless of
host).

Test count: 864 -> 873.

* Revert "fix(proxy/gemini): gate generic REST suffix stripping behind Google host in non-full-URL mode"

This reverts commit d19ff09cb7.

* test(proxy/gemini): pin non-full-URL versioned relay base stripping

Adds two regression tests that lock in the intentional asymmetry
between full-URL and non-full-URL modes:

- Full-URL mode: opaque base path (e.g. `https://relay.example/custom/v1beta`)
  is preserved verbatim. Already covered by
  `preserves_opaque_full_url_with_bare_v1beta_suffix`.
- Non-full-URL mode: base path MUST strip `/v1`, `/v1beta`, etc. so the
  standard `/v1beta/models/{model}:method` endpoint can be appended
  without producing a doubled `/v1beta/v1beta/models/...` path.

The non-full-URL contract is "base URL + cc-switch appends the
canonical Gemini endpoint". A user who needs a relay's custom
namespace (e.g. `/v1/models/...`) must use full-URL mode and paste
the complete method path. This commit adds regression coverage so a
future attempt to mirror full-URL's host-whitelist gating into
`normalize_gemini_base_path` will fail the test suite immediately.

* chore(lint): address clippy 1.95 findings in existing modules

CI upgraded to Rust 1.95 and flagged ten pre-existing warnings that
older toolchains did not enforce. None relate to the Gemini proxy
integration PR itself but they block CI on the feature branch, so
clean them up here as a separate commit for easy review:

collapsible_match:
- proxy/providers/gemini_schema.rs: `"items" if value.is_object()`
  match guard instead of nested if.
- proxy/providers/transform_responses.rs: fold
  `map_responses_stop_reason`'s `"completed"` / `"incomplete"` arms
  into match guards, relying on the existing `_ => "end_turn"` fall-
  through for non-matching guard conditions (semantics preserved).
- services/session_usage_codex.rs: fold
  `"session_meta" if state.session_id.is_none()` guard, relying on
  the existing `_ => {}` fall-through.

unnecessary_sort_by:
- services/provider/endpoints.rs: `sort_by_key(|ep| Reverse(ep.added_at))`.
- services/skill.rs (backup list): same Reverse idiom on `created_at`.
- services/skill.rs (skill listings x2): `sort_by_key(|s| s.name.to_lowercase())`.

useless_conversion:
- services/skill.rs: drop the explicit `.into_iter()` on `zip`'s argument.

while_let_loop:
- services/webdav_auto_sync.rs: `while let Some(wait_for) = ...`
  instead of `loop { let Some(...) = ... else { break }; ... }`.

All changes are mechanical and preserve behavior. `cargo test --lib`
remains green (868 passed).

* fix(proxy/gemini): reconcile synthesized tool-call ids with later real ids + preserve thoughtSignature

Three related findings on `streaming_gemini.rs` for Gemini's cumulative
`streamGenerateContent` stream, all centered on `merge_tool_call_snapshots`:

1. (P1) Match upgraded tool-call IDs by position.
   When Gemini delivers a `functionCall` without an id on chunk 1
   (cc-switch synthesizes `gemini_synth_*`) and then upgrades it to a
   real id on chunk 2, the `Some(incoming_id)` branch only matched by
   id and missed the existing synthesized snapshot. A second entry
   would be pushed, yielding duplicate `tool_use` content blocks at
   stream end — one with the synthesized id, one with the real id —
   which could trigger duplicate tool execution and break tool_result
   correlation. Add a positional fallback: when no id match exists but
   the same-position slot holds a synthesized id, merge into it.
   `or(preserved_id)` already lets the real id win the merge.

2. (P2) Preserve prior thoughtSignature when merging snapshots.
   `tool_call_snapshots[index] = tool_call` overwrote the slot
   entirely, dropping any `thoughtSignature` captured on an earlier
   chunk if the current cumulative snapshot omitted it. Since
   `build_shadow_assistant_parts` writes `thoughtSignature` into the
   shadow turn from `tool_call.thought_signature`, a dropped signature
   would cause later replay requests to Gemini to be rejected with
   invalid-signature errors. Preserve the existing signature when the
   incoming chunk does not carry one.

3. (P2) Document the part-order streaming trade-off.
   All `tool_use` content blocks are emitted after the final text
   `content_block_stop`, so interleaved [text, functionCall, text,
   functionCall] parts arrive at the Anthropic client as [text(concat),
   tool_use, tool_use] — different from the non-streaming transformer,
   which preserves part order. This is intentional given the cumulative
   snapshot model and the consumers we target (claude-code-like clients
   don't depend on strict interleaving for tool execution correctness).
   Add a block comment at the flush site describing the trade-off and
   what a strict-order fix would entail, so this isn't rediscovered as
   a bug later.

Regression tests:
- upgraded_real_id_merges_into_existing_synthesized_snapshot
- thought_signature_preserved_when_later_chunk_omits_it

Test count: 868 -> 870. clippy 1.95 clean. fmt clean.

* fix(proxy/gemini): prefer exact tool-call id over normalized-name fallback

The shadow-turn matcher used a three-branch `||` chain (id / full name /
normalized name). When two tools share a suffix (e.g. `server_a:search`
and `server_b:search`), the normalized-name clause could short-circuit
on an earlier turn whose id is actually wrong for the incoming tool_use,
mis-routing replay state (functionCall id / thoughtSignature) for later
tool_result resolution.

Split matching into two layers: when the incoming message carries any
tool_use ids, run id-based lookup first and return on the earliest hit.
Only fall back to full-name / normalized-name matching when the incoming
ids are absent or none of them resolve.

Add two regressions:

- shadow_replay_prefers_exact_id_match_over_normalized_name_collision
  Two shadow turns with colliding normalized names and two assistant
  messages whose ids cross the positional order; asserts each message
  replays the id-correct shadow turn (including thoughtSignature).

- shadow_replay_falls_back_to_name_when_ids_absent
  Shadow turn with no id and incoming tool_use with an empty id;
  asserts the name fallback still populates the replayed part.

Jason 6a34253934 feat: add Codex OAuth (ChatGPT Plus/Pro) reverse proxy support
Adds a new managed OAuth provider that lets Claude Code route requests
through a user's ChatGPT Plus/Pro subscription via the chatgpt.com
backend-api/codex endpoint.

- CodexOAuthManager: OpenAI Device Code flow with multi-account support,
  JWT-based account identification, and automatic access_token refresh.
- Reuses the generic managed-auth command surface (auth_start_login,
  auth_poll_for_account, etc.) via provider dispatch in commands/auth.rs.
- ClaudeAdapter detects codex_oauth providers, forces the base URL to
  the ChatGPT backend, pins api_format to openai_responses, and emits
  Authorization + originator headers; the forwarder injects the dynamic
  access_token and ChatGPT-Account-Id per request.
- transform_responses gains an is_codex_oauth path that aligns the body
  with OpenAI's codex-rs ResponsesApiRequest contract: sets store:false,
  appends reasoning.encrypted_content to include, strips max_output_tokens
  / temperature / top_p, injects default instructions/tools/parallel_tool_calls,
  and forces stream:true. Covered by 9 new unit tests plus regression
  guards for the non-Codex path.
- Stream check reuses the same transform flag so detection matches the
  production request shape.
- Frontend adds CodexOAuthSection + useCodexOauth hook, integrates it
  into ClaudeFormFields / ProviderForm / AuthCenterPanel, ships a new
  "Codex (ChatGPT Plus/Pro)" preset, and adds zh/en/ja i18n strings.

Jason 2513687184 feat: add Copilot optimizer to reduce premium interaction consumption
Implement request classification, tool result merging, compact detection,

The root cause was x-initiator being hardcoded to "user", making Copilot
count every API request (including tool callbacks and agent continuations)
as a separate premium interaction. The optimizer dynamically classifies
requests as "user" or "agent" based on message content analysis.

* fix: restore clear_auth() memory-first cleanup order and fix cache leaks

- Restore clear_auth() to clean memory state before deleting the storage
  file. The previous order (file deletion first) caused a regression where
  users could get stuck in a "cannot log out" state if file removal failed.

- Add missing copilot_models.clear() in clear_auth() — this cache was
  cleaned in remove_account() but never in the full clear path.

- Add endpoint_locks cleanup in both remove_account() and clear_auth()
  to prevent minor in-process memory leaks.

- Update test to assert the correct behavior: memory should be cleaned
  even when file deletion fails.

Dex Miller 67e074c0a7 refactor(proxy): transparent header forwarding via hyper client (#1714)
* style(frontend): reformat provider forms, constants and hooks

Apply prettier formatting across 5 frontend files. No logic changes.

Changed files:
- AddProviderDialog.tsx: reformat generic type annotation and callback
- ClaudeFormFields.tsx: consolidate multi-line useState and Collapsible props
- CodexConfigSections.tsx: expand single-line React imports to multi-line,
  collapse removeCodexTopLevelField() call
- constants.ts: merge TemplateType into single line
- useSkills.ts: expand single-line TanStack Query imports to multi-line,
  reformat uninstallSkill mutationFn chain

* deps(proxy): add hyper ecosystem crates and manual decompression libs

reqwest internally normalizes all header names to lowercase and does not
preserve insertion order, causing proxied requests to differ from the
original client requests. To achieve transparent header forwarding with
original casing and order, introduce lower-level hyper HTTP client libs.

New dependencies:
- hyper-util 0.1: TokioExecutor + legacy Client with
  preserve_header_case support for HTTP/1.1
- hyper-rustls 0.27: rustls-based TLS connector for hyper
- http 1 / http-body 1 / http-body-util 0.1: HTTP type crates for
  hyper 1.x request/response construction
- flate2 1: manual gzip/deflate decompression (replaces reqwest auto)
- brotli 7: manual brotli decompression

Changed dependencies:
- serde_json: enable preserve_order feature to keep JSON field order
- reqwest: drop gzip feature to prevent reqwest from overriding the
  client's original accept-encoding header

* refactor(proxy): use hyper client for header-case preserving forwarding

Previously the proxy used reqwest for all upstream requests. reqwest
normalizes header names to lowercase and reorders them internally,
making proxied requests distinguishable from direct CLI requests.
Some upstream providers are sensitive to these differences.

This commit replaces reqwest with a hyper-based HTTP client on the
default (non-proxy) path, achieving wire-level header fidelity:

Server layer (server.rs):
- Replace axum::serve with a manual hyper HTTP/1.1 accept loop
- Enable preserve_header_case(true) so incoming header casing is
  captured in a HeaderCaseMap extension on each request
- Bridge hyper requests to axum Router via tower::Service

New hyper client module (hyper_client.rs):
- Lazy-initialized hyper-util Client with preserve_header_case
- ProxyResponse enum wrapping both hyper::Response and reqwest::Response
  behind a unified interface (status, headers, bytes, bytes_stream)
- send_request() builds requests with ordered HeaderMap + case map

Request handlers (handlers.rs):
- Switch from (HeaderMap, Json<Value>) extractors to raw
  axum::extract::Request to preserve Extensions (containing the
  HeaderCaseMap from the accept loop)
- Pass extensions through the forwarding chain

Forwarder (forwarder.rs):
- Remove HEADER_BLACKLIST array; replace with ordered header iteration
  that preserves original header sequence and casing
- Build ordered_headers by iterating client headers, skipping only
  auth/host/content-length, and inserting auth headers at the original
  authorization position to maintain order
- Handle anthropic-beta (ensure claude-code-20250219 tag) and
  anthropic-version (passthrough or default) inline during iteration
- Remove should_force_identity_encoding() — accept-encoding is now
  transparently forwarded to upstream
- Use hyper client by default; fall back to reqwest only when an
  HTTP/SOCKS5 proxy tunnel is configured

Provider adapters (adapter.rs, claude.rs, codex.rs, gemini.rs):
- Replace add_auth_headers(RequestBuilder) -> RequestBuilder with
  get_auth_headers(AuthInfo) -> Vec<(HeaderName, HeaderValue)>
- Adapters now return header pairs instead of mutating a reqwest builder
- Claude adapter: merge Anthropic/ClaudeAuth/Bearer into single branch;
  move Copilot fingerprint headers into get_auth_headers

Response processing (response_processor.rs):
- Add manual decompression (gzip/deflate/brotli via flate2 + brotli)
  for non-streaming responses, since reqwest auto-decompression is now
  disabled to allow accept-encoding passthrough
- Add compressed-SSE warning log for streaming responses
- Accept ProxyResponse instead of reqwest::Response

HTTP client (http_client.rs):
- Disable reqwest auto-decompression (.no_gzip/.no_brotli/.no_deflate)
  on both global and per-provider clients

Streaming adapters (streaming.rs, streaming_responses.rs):
- Generalize stream error type from reqwest::Error to generic E: Error

Misc:
- log_codes.rs: add SRV-005 (ACCEPT_ERR) and SRV-006 (CONN_ERR)
- stream_check.rs: reformat copilot header lines
- transform.rs: fix trailing whitespace alignment

* fix(lint): resolve 35 clippy warnings across Rust codebase

Fix all clippy warnings reported by `cargo clippy --lib`:

- codex_config.rs: fix doc_overindented_list_items (3 spaces -> 2)
- commands/copilot.rs: inline format args in 2 log::error! calls
- commands/provider.rs: inline format args in 3 map_err closures
- proxy/hyper_client.rs: inline format arg in log::debug! call
- proxy/providers/copilot_auth.rs: inline format args in 16 locations
  (log macros, format! in headers, error constructors)
- proxy/thinking_optimizer.rs: inline format args in 2 log::info! calls
- services/skill.rs: inline format args in log::debug! call
- services/webdav_sync.rs: inline format args in 6 format! calls
  (version compat messages, download limit messages)
- services/webdav_sync/archive.rs: inline format args in 2 format! calls
- session_manager/providers/opencode.rs: inline format args in
  source_path format!

All fixes use the clippy::uninlined_format_args suggestion pattern:
  format!("msg: {}", var)  ->  format!("msg: {var}")

* deps(proxy): add raw HTTP write and native TLS cert dependencies

Add crates required for the raw TCP/TLS write path that bypasses
hyper's header encoder to preserve original header name casing:

- httparse: parse raw TCP peek bytes to capture header casings
- tokio-rustls + rustls: direct TLS connections for raw write path
- webpki-roots: Mozilla CA bundle baseline
- rustls-native-certs: load system keychain CAs (trusts proxy MITM
  certificates from Clash, mitmproxy, etc.)

* fix(proxy): address code review feedback on response handling

Fixes from PR #1714 code review:

- Extract `read_decoded_body()` and `strip_entity_headers_for_rebuilt_body()`
  in response_processor to properly clean content-encoding/content-length
  headers after decompression
- Reuse `read_decoded_body()` in handlers.rs for Claude transform path,
  ensuring compressed responses are decoded before format conversion
- Make `build_proxy_url_from_config()` public so forwarder can pass proxy
  URL to the hyper raw write path
- Add `has_system_proxy_env()` utility with test coverage
- Add 50ms backoff after accept() failures in server.rs to prevent
  tight-loop CPU spin on transient socket errors

* feat(proxy): implement raw TCP/TLS write with HTTP CONNECT tunnel

Rewrite hyper_client with a two-tier strategy for header case preservation:

Primary path (raw write):
- Peek raw TCP bytes in server.rs to capture OriginalHeaderCases before
  hyper lowercases them
- Build raw HTTP/1.1 request bytes with exact original header name casing
- Write directly to TLS stream, then use WriteFilter to let hyper parse
  the response while discarding its duplicate request writes
- Support HTTP CONNECT tunneling through upstream proxies, so header case
  is preserved even when a proxy (Clash, V2Ray) is configured

Fallback path (hyper-util Client):
- Used when OriginalHeaderCases is empty or raw write fails
- Configured with title_case_headers(true) for best-effort casing

TLS improvements:
- Load native system certificates alongside webpki roots so proxy MITM
  CAs (installed in system keychain) are trusted through CONNECT tunnels

Key types added:
- OriginalHeaderCases: maps lowercase name → original wire-casing bytes
- WriteFilter<S>: AsyncRead+AsyncWrite wrapper that discards writes
- connect_via_proxy(): HTTP CONNECT tunnel establishment
- ExtensionDebugMarker: diagnostic marker for extension chain debugging

* refactor(proxy): route requests through hyper with proxy-aware forwarding

Rework forwarder request dispatch to always prefer the hyper raw write
path (header case preservation) over reqwest:

Request routing:
- HTTP/HTTPS proxy: hyper raw write through CONNECT tunnel (case preserved)
- SOCKS5 proxy: reqwest fallback (CONNECT not supported for SOCKS5)
- No proxy: hyper raw write direct connection

Header handling improvements:
- Replace host header in-place at original position instead of
  skip-and-append, preserving client's header ordering
- Preserve client's original accept-encoding for transparent passthrough;
  only force identity encoding when transform path needs decompression
- Add should_force_identity_encoding() to centralize the decision
- Remove hardcoded 'br, gzip, deflate' override that masked client values

Proxy URL resolution (priority order):
1. Provider-specific proxy config (if enabled)
2. Global proxy URL configured in CC Switch
3. Direct connection (no proxy)

* chore(proxy): remove dead code, redundant tests and debug scaffolding

- Inline should_force_identity_encoding() (was just `needs_transform`)
  and delete its 5 test cases
- Remove ExtensionDebugMarker diagnostic type
- Remove unused has_system_proxy_env() and its test
- Remove strip_entity_headers test
- Simplify hyper path: remove redundant is_socks_proxy ternary
- Update hyper_client module doc to reflect CONNECT tunnel support

* fix(proxy): block direct-connect fallback and complete CONNECT tunnel support

* feat(hooks): improve proxy requirement warnings with specific reasons

- Remove redundant OpenAI format hint toast messages
- Add detailed reason detection for proxy requirements (OpenAI Chat, OpenAI Responses, full URL mode)
- Update i18n files with new reason-specific keys

* style(*): format code with prettier

- Remove extra whitespace in http_client.rs
- Fix formatting issues in useProviderActions.ts

* fix(proxy): post-merge fixes for forward return type and clippy warnings

- Restore forward() return type to (ProxyResponse, Option<String>)
  to pass claude_api_format through to callers
- Inline format args in log::warn! macro (clippy::uninlined_format_args)
- Suppress too_many_arguments for check_claude_stream

* refactor(proxy): preserve original header wire order and add non-streaming body timeout

- Rewrite build_raw_request to emit headers in original
  client-sent sequence instead of hash-map order
- Remove unused OriginalHeaderCases::get_all method
- Add body_timeout to read_decoded_body to prevent
  requests hanging when upstream stalls after headers

* 修复用量查询Reset字段出现多余字符

* refactor(auth-binding): introduce generic provider auth binding primitives

- add shared authBinding types in Rust and TypeScript while keeping githubAccountId as a compatibility field\n- resolve Copilot token, models, and usage through provider-bound account lookup instead of only the implicit default account\n- fix the Unix build regression in settings.rs by restoring std::io::Write for write_all()\n- remove the accidental .github ignore entry and drop leftover Copilot form debug logs\n- keep the first migration step non-breaking by writing both authBinding and the legacy githubAccountId field from the form

* refactor(auth-service): add managed auth command surface and explicit default account state

- introduce generic managed auth commands and frontend auth API wrappers for provider-scoped login, status, account listing, removal, logout, and default-account selection\n- store an explicit Copilot default_account_id instead of relying on HashMap iteration order, and use it consistently for fallback token/model/usage resolution\n- sort managed accounts deterministically and surface default-account state to the UI\n- refactor the Copilot form hook to wrap a generic useManagedAuth implementation while preserving the existing component contract\n- add default-account controls to the Copilot auth section and extend Copilot auth status serialization/tests for the new state

* feat(add-provider): expose managed OAuth sources alongside universal providers

- add an OAuth tab to the Add Provider flow so managed auth sources sit beside app-specific and universal providers\n- reuse the new Auth Center panel inside the dialog, keeping account management discoverable during provider creation\n- make the dialog footer adapt to the OAuth tab so account setup does not pretend to create a provider directly\n- align the add-provider UX with the new architecture where OAuth accounts are global assets and providers bind to them later

* fix(auth-reliability): harden managed auth persistence and refresh behavior

- replace direct Copilot auth store writes with private temp-file writes and atomic rename semantics, and document the local token storage limitation\n- add per-account refresh locks plus a double-check path so concurrent requests do not stampede GitHub token refresh\n- surface legacy migration failures through auth status, expose them in the UI, and add translated copy for the new account-state labels\n- stop writing the legacy githubAccountId field from the provider form while keeping compatibility reads in place\n- add logout error recovery and Copilot model-load toasts so auth failures are no longer silently swallowed

* refactor(copilot-detection): prefer provider type before URL fallbacks

- update forwarder endpoint rewriting to treat providerType as the primary GitHub Copilot signal\n- keep githubcopilot.com string matching only as a compatibility fallback for older provider records without providerType\n- reduce one more path where Copilot behavior depended purely on URL heuristics

* fix(copilot-auth): add cancel button to error state in CopilotAuthSection

- 错误状态下仅有"重试"按钮,用户无法退出(如不可恢复的 403 未订阅错误)
- 新增"取消"按钮,复用已有的 cancelAuth 逻辑重置为 idle 状态

Jason 28afbea917 fix(proxy): enable gzip compression for non-streaming proxy requests
Non-streaming requests were forced to use `Accept-Encoding: identity`,
preventing upstream response compression and increasing bandwidth usage.

Now only streaming requests conservatively keep `identity` to avoid
decompression errors on interrupted SSE streams. Non-streaming requests
let reqwest auto-negotiate gzip and transparently decompress responses.

Keith Yu 8217bfff50 feat: add Bedrock request optimizer (PRE-SEND thinking + cache injection) (#1301)
* feat: add Bedrock request optimizer (PRE-SEND thinking + cache injection)

Add a PRE-SEND request optimizer that enhances Bedrock API requests
before forwarding, complementing the existing POST-ERROR rectifier system.

New modules:
- thinking_optimizer: 3-path model detection (adaptive/legacy/skip)
  - Opus 4.6/Sonnet 4.6: adaptive thinking + effort max + 1M context beta
  - Legacy models: inject extended thinking with max budget
  - Haiku: skip (no modification)
- cache_injector: auto-inject cache_control breakpoints (max 4)
  - Injects at tools/system/assistant message positions
  - TTL upgrade for existing breakpoints (5m → 1h)

Gate: only activates for Bedrock providers (CLAUDE_CODE_USE_BEDROCK=1)
Config: stored in SQLite settings table, default OFF, user opt-in
UI: new Optimizer section in RectifierConfigPanel with 3 toggles + TTL

18 unit tests covering all paths. Verified against live Bedrock API.

* chore: remove docs/plans directory

* fix: address code review findings for Bedrock request optimizer

P0 fixes:
- Replace hardcoded Chinese with i18n t() calls in optimizer panel,
  add translation keys to zh/en/ja locale files
- Fix u64 underflow: max_tokens - 1 → max_tokens.saturating_sub(1)
- Move optimizer from before retry loop to per-provider with body
  cloning, preventing Bedrock fields leaking to non-Bedrock providers

P1 fixes:
- Replace .map() side-effect pattern with idiomatic if-let (clippy)
- Fix module alphabetical ordering in mod.rs
- Add cache_ttl whitelist validation in set_optimizer_config
- Remove #[allow(unused_assignments)] and dead budget decrement

Andrew Leng 0dd823ae3a fix(codex): fix 404 errors and connection timeout with custom base_url (#760)
* fix(proxy): fix Codex 404 errors with custom base_url prefixes

- handlers.rs:268: Remove hardcoded /v1 prefix in Codex forwarding
- codex.rs:140: Only add /v1 for origin-only base_urls, dedupe /v1/v1
- stream_check.rs:364: Try /responses first, fallback to /v1/responses
- provider.rs:427: Don't force /v1 for custom prefix base_urls

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(codex): always add /v1 for custom prefix base_urls

Changed logic to always add /v1 prefix unless base_url already ends with /v1.
This fixes 504 timeout errors with relay services that expect /v1 in the path.

- Most relay services follow OpenAI standard format: /v1/responses
- Users can opt-out by adding /v1 to their base_url configuration
- Updated test case to reflect new behavior

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(proxy): allow system proxy on localhost with different ports

- Only bypass system proxy if it points to CC Switch's own port (15721)
- Allow other localhost proxies (e.g., Clash on 7890) to be used
- Add INFO level logging for request URLs to aid debugging

This fixes connection timeout issues when using local proxy tools.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(codex): don't add /v1 for custom prefix base_urls

Reverted logic to not add /v1 for base_urls with custom prefixes.
Many relay services use custom paths without /v1.

- Pure origin (e.g., https://api.openai.com) → adds /v1
- With /v1 (e.g., https://api.openai.com/v1) → no change
- Custom prefix (e.g., https://example.com/openai) → no /v1

This fixes 404 errors with relay services that don't use /v1 in their paths.

* fix(proxy): use dynamic port for system proxy detection

Instead of hardcoding port 15721, now uses the actual configured
listen_port from proxy settings.

- Added set_proxy_port() to update the port when proxy server starts
- Added get_proxy_port() to retrieve current port for detection
- Updated server.rs to call set_proxy_port() on startup
- Updated tests to reflect new behavior

This allows users to change the proxy port in settings without
breaking the system proxy detection logic.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(proxy): change default proxy port from 15721 to 5000

Update the default fallback port in get_proxy_port() from 15721 to 5000
to match the project's standard default port configuration.

Also updated test cases to use port 5000 consistently.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(proxy): revert default port back to 15721

Revert the default fallback port in get_proxy_port() from 5000 back to 15721
to align with the project's updated default port configuration.

Also updated test cases to use port 15721 consistently.

* feat(proxy): add request logging for debugging

Add debug logs for outgoing requests including URL and body content
with byte size, matching the existing response logging format.

* fix(log): prevent usize underflow in KeepSome rotation strategy

KeepSome(n) internally computes n-2, so n=1 causes underflow.
Use KeepSome(2) as the minimum safe value.

Jason Young a268127f1f Fix/Resolve panic issues in proxy-related code (#560)
* fix(proxy): change default port from 5000 to 15721

Port 5000 conflicts with AirPlay Receiver on macOS 12+.
Also adds error handling for proxy toggle and i18n placeholder updates.

* fix(proxy): replace unwrap/expect with graceful error handling

- Handle HTTP client initialization failure with no_proxy fallback
- Fix potential panic on Unicode slicing in API key preview
- Add proper error handling for response body builder
- Handle edge case where SystemTime is before UNIX_EPOCH

* fix(proxy): handle UTF-8 char boundary when truncating request body log

Rust strings are UTF-8 encoded, slicing at a fixed byte index may cut
in the middle of a multi-byte character (e.g., Chinese, emoji), causing
a panic. Use is_char_boundary() to find the nearest safe cut point.

* fix(proxy): improve robustness and prevent panics

- Add reqwest socks feature to support SOCKS proxy environments
- Fix UTF-8 safety in masked_key/masked_access_token (use chars() instead of byte slicing)
- Fix UTF-8 boundary check in usage_script HTTP response truncation
- Add defensive checks for JSON operations in proxy service
- Remove verbose debug logs that could trigger panic-prone code paths

Dex Miller 847f1c5377 Feat/proxy header improvements (#538)
* fix(proxy): improve header handling for Claude API compatibility

- Streamline header blacklist by removing overly aggressive filtering
  (browser-specific headers like sec-fetch-*, accept-language)
- Ensure anthropic-beta header always includes 'claude-code-20250219'
  marker required by upstream services for request validation
- Centralize anthropic-version header handling in forwarder to prevent
  duplicate headers across different auth strategies
- Add ?beta=true query parameter to /v1/messages endpoint for
  compatibility with certain upstream services (e.g., DuckCoding)
- Remove redundant anthropic-version from ClaudeAdapter auth headers
  as it's now managed exclusively by the forwarder

This improves proxy reliability with various Claude API endpoints
and third-party services that have specific header requirements.

* style(services): use inline format arguments in format strings

Apply Rust 1.58+ format string syntax across provider and skill
services. This replaces format!("msg {}", var) with format!("msg {var}")
for improved readability and consistency with modern Rust idioms.

Changed files:
- services/provider/mod.rs: 1 format string
- services/skill.rs: 10 format strings (error messages, log statements)

No functional changes, purely stylistic improvement.

* fix(proxy): restrict Anthropic headers to Claude adapter only

- Move anthropic-beta and anthropic-version header handling inside
  Claude-specific condition to avoid sending unnecessary headers
  to Codex and Gemini APIs
- Update test cases to reflect ?beta=true query parameter behavior
- Add edge case tests for non-messages endpoints and existing queries
2026-01-08 11:04:42 +08:00
Dex Miller 5376ea042b Feat/usage improvements (#508)
* i18n: update cache terminology across all languages

- Change 'Cache Read' to 'Cache Hit' in all languages
- Change 'Cache Write' to 'Cache Creation' in all languages
- Update zh: 缓存读取 → 缓存命中, 缓存写入 → 缓存创建
- Update en: Cache Read → Cache Hit, Cache Write → Cache Creation
- Update ja: キャッシュ読取 → キャッシュヒット, キャッシュ書込 → キャッシュ作成

Affected keys: cacheReadTokens, cacheCreationTokens, cacheReadCost,
cacheWriteCost, cacheRead, cacheWrite

* feat(usage): add cache metrics to trend chart

- Add cache creation tokens visualization (orange line)
- Add cache hit tokens visualization (purple line)
- Add gradient definitions for new cache metrics
- Include cache data in hourly aggregation
- Display cache metrics alongside input/output tokens

This provides better visibility into cache usage patterns over time.

* fix(usage): fix timezone handling in datetime picker

- Add timestampToLocalDatetime() to convert Unix timestamp to local datetime
- Add localDatetimeToTimestamp() with validation for incomplete input
- Fix issue where typing hours/minutes would jump to previous day
- Validate datetime format completeness before conversion
- Use local timezone instead of UTC for datetime-local input

This resolves the issue where users couldn't fine-tune time selection
and the input would jump unexpectedly when editing hours or minutes.

* feat(usage): add auto-refresh for usage statistics

- Add 30-second auto-refresh interval for all usage queries
- Disable background refresh to save resources
- Apply to: summary, trends, provider stats, model stats, request logs
- Queries automatically update when tab is active
- Pause refresh when user switches to another tab

This keeps usage data fresh without manual refresh.

* fix(proxy): improve usage logging and cache token parsing

- Log requests even when usage parsing fails (with default values)
- Add detailed debug logging for usage metrics
- Support cache_read_input_tokens field in Codex responses
- Fallback to input_tokens_details.cached_tokens if needed
- Add test case for cached_tokens in input_tokens_details
- Ensure all requests are tracked in database for analytics

This fixes missing request logs when API responses lack usage data
and improves cache token detection across different response formats.

* style(rust): use inline format args in format! macros

- Replace format!("...", var) with format!("...{var}")
- Update universal provider ID formatting
- Update error message formatting
- Update config.toml generation in Codex provider

Fixes clippy::uninlined_format_args warnings.

* feat(proxy): enhance provider router logging

- Add debug logs for failover queue provider count
- Log circuit breaker state for each provider check
- Add logs for missing current provider scenarios
- Log when no current provider is configured
- Use inline format args for better readability

This improves debugging of provider selection and failover behavior.

* feat(database): update model pricing data

- Update Claude models to full version format (e.g. claude-opus-4-5-20251101)
- Add GPT-5.2 series model pricing (10 models)
- Add GPT-5.1 series model pricing (10 models)
- Add GPT-5 series model pricing (12 models)
- Add Gemini 3 series model pricing (2 models)
- Update Gemini 2.5 series model ID format (use dot separator)
- Unify display names by removing thinking level suffixes

* fix(usage): correct Gemini output token calculation

Fix Gemini API output token parsing to use totalTokenCount - promptTokenCount
instead of candidatesTokenCount alone. This ensures thoughtsTokenCount is
included in output statistics.

- Update from_gemini_response to calculate output from total - input
- Update from_gemini_stream_chunks with same logic for consistency
- Fix from_codex_stream_events to use adjusted token calculation
- Add test case for responses with thoughtsTokenCount
- Update existing tests to match new calculation logic

* fix(usage): correct cache token billing and add Codex format auto-detection

- Avoid double-billing cache tokens by subtracting from input before calculation
- Add smart Codex parser that auto-detects OpenAI vs Codex API format
- Extract model name from Codex responses for accurate tracking

* fix(proxy): improve takeover detection with live config check

- Add live config takeover detection for hot-switch decision
- Rebuild takeover when backup is missing or placeholder remains
- Make detect_takeover_in_live_config_for_app public
- Fix is_takeover_active to use actual takeover status

* refactor(usage): simplify model pricing lookup by removing suffix fallback

Replace complex suffix-stripping fallback with direct prefix/suffix cleanup.
Model IDs are now cleaned by removing vendor prefix (before /) and colon
suffix (after :), then matched exactly against pricing table.

* feat(database): add Chinese AI model pricing data

Add pricing for domestic AI models (CNY/1M tokens):
- Doubao-Seed-Code (ByteDance)
- DeepSeek V3/V3.1/V3.2
- Kimi K2/K2-Thinking/K2-Turbo (Moonshot)
- MiniMax M2/M2.1/M2.1-Lightning
- GLM-4.6/4.7 (Zhipu)
- Mimo V2 Flash (Xiaomi)

Also fix test case to use correct model ID and remove invalid currency column.

* refactor(proxy): improve header forwarding with blacklist approach

Change from whitelist to blacklist mode for request header forwarding.
Only skip headers that will be overridden (auth, host, content-length).
This preserves client's original headers and improves compatibility.

* fix(proxy): bypass timeout and retry configs when failover is disabled

When auto_failover_enabled is false, timeout and retry configurations
should not affect normal request flow. This change ensures:

- create_forwarder: passes 0 for all timeout/retry params when failover
  is disabled, effectively bypassing these checks
- streaming_timeout_config: returns 0 for both first_byte_timeout and
  idle_timeout when failover is disabled

This prevents unnecessary timeout errors and retry attempts when users
have explicitly disabled the failover feature.

* fix(proxy): handle zero value input in failover config fields

* refactor(proxy): remove retry logic and add enabled check for failover

* refactor(proxy): distinguish circuit-open from no-provider errors

* Align usage stats to sliding windows

* feat(proxy): add body and header filtering for upstream requests

* feat(proxy): enable transparent passthrough for headers

- Passthrough anthropic-beta header as-is from client
- Passthrough anthropic-version header from client
- Passthrough client IP headers (x-forwarded-for, x-real-ip) by default
- Filter private params (underscore-prefixed fields) from request body
- No database changes required

* feat(proxy): extract session ID from client requests for logging

- Add SessionIdExtractor to parse session ID from Claude/Codex requests
- Support extraction from metadata.user_id, headers, previous_response_id
- Pass session_id through RequestContext to usage logger
- Enable request correlation by session in proxy_request_logs

YoVinchen e6f18ba801 Feat/usage model extraction (#455)
* feat(proxy): extract model name from API response for accurate usage tracking

- Add model field extraction in TokenUsage parsing for Claude, OpenAI, and Codex
- Prioritize response model over request model in usage logging
- Update model extractors to use parsed usage.model first
- Add tests for model extraction in stream and non-stream responses

* feat(proxy): implement streaming timeout control with validation

- Add first byte timeout (0 or 1-180s) for streaming requests
- Add idle timeout (0 or 60-600s) for streaming data gaps
- Add non-streaming timeout (0 or 60-1800s) for total request
- Implement timeout logic in response processor
- Add 1800s global timeout fallback when disabled
- Add database schema migration for timeout fields
- Add i18n translations for timeout settings

- Add model_mapper.rs with ModelMapping struct to extract model configs from Provider
- Support ANTHROPIC_MODEL, ANTHROPIC_REASONING_MODEL, and default models for haiku/sonnet/opus
- Implement thinking mode detection for reasoning model priority
- Include comprehensive unit tests for all mapping scenarios

* fix(proxy): bypass circuit breaker for single provider scenario

When failover is disabled (single provider), circuit breaker open state
would block all requests causing poor UX. Now bypasses circuit breaker
check in this scenario. Also integrates model mapping into request flow.

* feat(ui): add reasoning model field to Claude provider form

Add ANTHROPIC_REASONING_MODEL configuration field for Claude providers,
allowing users to specify a dedicated model for thinking/reasoning tasks.

* feat(proxy): add openrouter_compat_mode for optional format conversion

Add configurable OpenRouter compatibility mode that enables Anthropic to
OpenAI format conversion. When enabled, rewrites endpoint to /v1/chat/completions
and transforms request/response formats. Defaults to enabled for OpenRouter.

* feat(ui): add OpenRouter compatibility mode toggle

Add UI toggle for OpenRouter providers to enable/disable compatibility
mode which uses OpenAI Chat Completions format with SSE conversion.

* feat(stream-check): use provider-configured model for health checks

Extract model from provider's settings_config (ANTHROPIC_MODEL, GEMINI_MODEL,
or Codex config.toml) instead of always using default test models.

* refactor(ui): remove timeout settings from AutoFailoverConfigPanel

Remove streaming/non-streaming timeout configuration from failover panel
as these settings have been moved to a dedicated location.

* refactor(database): migrate proxy_config to per-app three-row structure

Replace singleton proxy_config table with app_type primary key structure,
allowing independent proxy settings for Claude, Codex, and Gemini.
Add GlobalProxyConfig queries and per-app config management in DAO layer.

* feat(proxy): add GlobalProxyConfig and AppProxyConfig types

Add new type definitions for the refactored proxy configuration:
- GlobalProxyConfig: shared settings (enabled, address, port, logging)
- AppProxyConfig: per-app settings (failover, timeouts, circuit breaker)

* refactor(proxy): update service layer for per-app config structure

Adapt proxy service, handler context, and provider router to use
the new per-app configuration model. Read enabled/timeout settings
from proxy_config table instead of settings table.

* feat(commands): add global and per-app proxy config commands

Add new Tauri commands for the refactored proxy configuration:
- get_global_proxy_config / update_global_proxy_config
- get_proxy_config_for_app / update_proxy_config_for_app
Update startup restore logic to read from proxy_config table.

* feat(api): add frontend API and Query hooks for proxy config

Add TypeScript wrappers and TanStack Query hooks for:
- Global proxy config (address, port, logging)
- Per-app proxy config (failover, timeouts, circuit breaker)
- Proxy takeover status management

* refactor(ui): redesign proxy panel with inline config controls

Replace ProxySettingsDialog with inline controls in ProxyPanel.
Add per-app takeover switches and global address/port settings.
Simplify AutoFailoverConfigPanel by removing timeout settings.

* feat(i18n): add proxy takeover translations and update types

Add i18n strings for proxy takeover status in zh/en/ja.
Update TypeScript types for GlobalProxyConfig and AppProxyConfig.

* refactor(proxy): load circuit breaker config per-app instead of globally

Extract app_type from router key and read circuit breaker settings
from the corresponding proxy_config row for each application.

YoVinchen 1586451862 Feat/auto failover switch (#440)
* feat(failover): add auto-failover master switch with proxy integration

- Add persistent auto_failover_enabled setting in database
- Add get/set_auto_failover_enabled commands
- Provider router respects master switch state
- Proxy shutdown automatically disables failover
- Enabling failover auto-starts proxy server
- Optimistic updates for failover queue toggle

* feat(proxy): persist proxy takeover state across app restarts

- Add proxy_takeover_{app_type} settings for per-app state tracking
- Restore proxy takeover state automatically on app startup
- Preserve state on normal exit, clear on manual stop
- Add stop_with_restore_keep_state method for graceful shutdown

* fix(proxy): set takeover state for all apps in start_with_takeover

* fix(windows): hide console window when checking CLI versions

Add CREATE_NO_WINDOW flag to prevent command prompt from flashing
when detecting claude/codex/gemini CLI versions on Windows.

* refactor(failover): make auto-failover toggle per-app independent

- Change setting key from 'auto_failover_enabled' to 'auto_failover_enabled_{app_type}'
- Update provider_router to check per-app failover setting
- When failover disabled, use current provider only; when enabled, use queue order
- Add unit tests for failover enabled/disabled behavior

* feat(failover): auto-switch to higher priority provider on recovery

- After circuit breaker reset, check if recovered provider has higher priority
- Automatically switch back if queue_order is lower (higher priority)
- Stream health check now resets circuit breaker on success/degraded

* chore: remove unused start_proxy_with_takeover command

- Remove command registration from lib.rs
- Add comment clarifying failover queue is preserved on proxy stop

* feat(ui): integrate failover controls into provider cards

- Add failover toggle button to provider card actions
- Show priority badge (P1, P2, ...) for queued providers
- Highlight active provider with green border in failover mode
- Sync drag-drop order with failover queue
- Move per-app failover toggle to FailoverQueueManager
- Simplify SettingsPage failover section

* test(providers): add mocks for failover hooks in ProviderList tests

* refactor(failover): merge failover_queue table into providers

- Add in_failover_queue field to providers table
- Remove standalone failover_queue table and related indexes
- Simplify queue ordering by reusing sort_index field
- Remove reorder_failover_queue and set_failover_item_enabled commands
- Update frontend to use simplified FailoverQueueItem type

* fix(database): ensure in_failover_queue column exists for v2 databases

Add column check in create_tables to handle existing v2 databases
that were created before the failover queue refactor.

* fix(ui): differentiate active provider border color by proxy mode

- Use green border/gradient when proxy takeover is active
- Use blue border/gradient in normal mode (no proxy)
- Improves visual distinction between proxy and non-proxy states

* fix(database): clear provider health record when removing from failover queue

When a provider is removed from the failover queue, its health monitoring
is no longer needed. This change ensures the health record is also deleted
from the database to prevent stale data.

* fix(failover): improve cache cleanup for provider health and circuit breaker

- Use removeQueries instead of invalidateQueries when stopping proxy to
  completely clear health and circuit breaker caches
- Clear provider health and circuit breaker caches when removing from
  failover queue
- Refresh failover queue after drag-sort since queue order depends on
  sort_index
- Only show health badge when provider is in failover queue

* style: apply prettier formatting to App.tsx and ProviderList.tsx

* fix(proxy): handle missing health records and clear health on proxy stop

- Return default healthy state when provider health record not found
- Add clear_provider_health_for_app to clear health for specific app
- Clear app health records when stopping proxy takeover

* fix(proxy): track actual provider used in forwarding for accurate logging

Introduce ForwardResult and ForwardError structs to return the actual
provider that handled the request. This ensures usage statistics and
error logs reflect the correct provider after failover.
