Jason b02b8f3b1b 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.

Jason 1f3ebe9c62 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.

Jason baaefcc2fc 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.

Jason 8b65488a89 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.

Jason 128d431084 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.

YoVinchen 2309b49ed5 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
Reversibility: clean
Directive: Preserve Gemini shadow continuity across requests by keying Claude sessions from the header first and persisting tool-call shadow before yielding tool_use events downstream

YoVinchen 8bdc4d6326 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

global proxy panel.

Changes:
- Remove ProviderProxyConfig type (frontend TS + backend Rust)
- Remove ProviderAdvancedConfig proxy UI block, keep testConfig/pricingConfig
- Simplify http_client: delete build_proxy_url_from_config,
  build_client_for_provider, get_for_provider
- Simplify forwarder/stream_check/model_fetch to use global client
- Remove i18n keys (en/zh/ja)

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.

Cod1ng dc4524e960 fix: handle UTF-8 multi-byte characters split across stream chunk boundaries (#1923)
* fix: handle UTF-8 multi-byte characters split across stream chunk boundaries

Replace String::from_utf8_lossy with append_utf8_safe in all four SSE
streaming paths. When a multi-byte UTF-8 character (e.g. Chinese, emoji)
is split across TCP chunk boundaries, from_utf8_lossy silently replaces
the incomplete halves with U+FFFD (�). This caused intermittent garbled
output in Claude Code when using the Copilot reverse proxy, because the
format conversion streams reconstruct SSE events from the corrupted buffer.

The new append_utf8_safe function preserves incomplete trailing bytes in
a remainder buffer and merges them with the next chunk before decoding,
ensuring characters are never split during UTF-8 conversion.

Fixes: intermittent U+FFFD replacement characters in Claude Code output
via Copilot proxy (not reproducible with direct Copilot connections like
opencode because they pass through raw bytes without format conversion).

* style: fix cargo fmt formatting in UTF-8 boundary tests

Jason 2513687184 feat: add Copilot optimizer to reduce premium interaction consumption
Implement request classification, tool result merging, compact detection,
deterministic request IDs, and warmup downgrade for Copilot proxy.

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 96a0a37331 feat(terminal): add directory picker before launching Claude terminal (#1752)
* Add directory picker before launching Claude terminal

* fix(terminal): preserve cwd path and strip Windows verbatim prefix

- Stop trimming non-empty paths so directories with leading/trailing
  spaces on Unix are handled correctly
- Strip \\?\ extended-length prefix from canonicalized paths on Windows
  to prevent batch script cd failures

* fix(terminal): restore UNC paths when stripping Windows verbatim prefix

Handle \\?\UNC\server\share form separately from regular \\?\ prefix,
converting it back to \\server\share so network/WSL directory paths
remain valid in batch cd commands.

* fix(terminal): use pushd for UNC paths in Windows batch launcher

`cmd.exe` cannot set a UNC path (e.g. `\\wsl$\...`) as the current
directory via `cd /d`; it errors with "CMD does not support UNC paths
as current directories". Switch to `pushd` which temporarily maps the
UNC share to a drive letter.

Rename `build_windows_cd_command` → `build_windows_cwd_command` to
reflect the broader semantics. Extract `build_windows_cwd_command_str`
and `is_windows_unc_path` helpers for testability, and add unit tests
covering drive paths, UNC paths, and batch metacharacter escaping.

Also fix minor style issues: sort mod declarations alphabetically,
add missing EOF newline in lightweight.rs, add explicit type annotation
in streaming_responses test, and reformat tray menu builder chain.

- 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

2. Fallback: thinking.type + budget_tokens thresholds (<4k → low,
   4k-16k → medium, ≥16k → high, adaptive → high)

* 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(auth-center): add a dedicated settings entrypoint for managed OAuth accounts

- add an Auth Center tab to Settings so managed OAuth accounts are no longer hidden inside individual provider forms\n- introduce a first AuthCenterPanel that hosts GitHub Copilot account management as the initial managed auth provider\n- keep the provider form experience intact while establishing a global account-management surface for future providers such as OpenAI\n- validate that the new settings tab works cleanly with the generic managed auth hook and existing Copilot account controls

* 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

* 修复打包后github账号头像显示异常

* 修复github copilot 来源的模型测试报错

* feat(copilot-preset): add default model presets for GitHub Copilot

- 补充 Copilot 预设的默认模型配置,用户选完预设即可直接使用
- ANTHROPIC_MODEL: claude-opus-4.6
- ANTHROPIC_DEFAULT_HAIKU_MODEL: claude-haiku-4.5
- ANTHROPIC_DEFAULT_SONNET_MODEL: claude-sonnet-4.6

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.

Hemilt0n f38facd430 fix(proxy): use max_completion_tokens for o1/o3 series models (#1451)
* fix(proxy): use max_completion_tokens for o1/o3 series models

When converting Anthropic requests to OpenAI format for o1/o3 series
models (like o1-mini, o3-mini), use max_completion_tokens instead of
max_tokens to avoid unsupported_parameter errors.

Fixes #1448

* fix: revert incorrect o-series max_completion_tokens in Responses API path

Responses API uses max_output_tokens for all models including o-series.
The o-series max_completion_tokens fix should only apply to Chat Completions API.

Jason 9092e97bc2 style: format Rust code with cargo fmt 2026-03-08 22:27:53 +08:00
Jason bf40b0138c feat: add usage daily rollups, incremental auto-vacuum, and sync-aware backup
- Add usage_daily_rollups table (schema v6) to aggregate proxy request
  logs into daily summaries, reducing query overhead for statistics
- Add rollup_and_prune DAO that aggregates old detail logs (>N days)
  into rollup rows and deletes the originals
- Update all usage stats queries to UNION detail logs with rollup data
- Introduce incremental auto-vacuum for SQLite, with startup and
  periodic cleanup of old stream_check_logs and request log rollups
- Split backup export/import into full vs sync variants: WebDAV sync
  now skips local-only table data (proxy_request_logs,
  stream_check_logs, provider_health, proxy_live_backup,
  usage_daily_rollups) while preserving them on import
- Add enable_logging guard to skip request log writes when disabled
- Apply cargo fmt formatting fixes across multiple modules

Jason 50a2bd29e6 fix: correct OpenAI ChatCompletion to Anthropic Messages streaming conversion
Rewrite tool call handling in streaming format conversion to properly
track multiple concurrent tool blocks with independent Anthropic content
indices. Fix block interleaving (thinking/text/tool_use) with correct
content_block_start/stop events, buffer tool arguments until both id and
name are available, and add tool result message conversion in transform.
