- Create a fresh uTLS/HTTP-2 connection per request instead of reusing cached connections.
- Pass request context through dialing and TLS handshake to make `RoundTrip` cancelable.
- Wrap response bodies so the underlying HTTP/2 connection is closed when the body is closed, and clean up promptly on request/response failures.
Closes: #4878
Classify malformed caller metadata and Fast failures as request-scoped, reuse the strict Anthropic origin gate, bound diagnostics and proxy caches, and remove the unrelated translator test change.
Align the remaining measured OAuth wire profiles, including the ordered
connection writer in internal/httpwire that reproduces the observed header
sequence, and the refresh/profile response shapes in internal/auth/claude.
Replay the measured Fast path and keep diagnostic continuity across cloaked and
native requests.
Preserve the native direct token-counting shape so a caller that reaches
count_tokens itself is not reshaped into the cloaked form.
Scope cloak dates to the credential's timezone rather than the host's, so
currentDate matches what the real client would have sent for that account.
Detect confirmed CLI, sdk-cli and VSCode callers before mutation so native
software, system, tool, cache and beta shapes pass through, while unconfirmed
OAuth clients receive a coherent minimum CLI identity.
Persist each Claude OAuth credential's upstream account metadata and one stable
device ID, derive one stable session per agent conversation, and keep body and
header identity synchronized across Messages, streaming and count_tokens.
Alias every cloaked third-party custom tool through caller-stable opaque MCP
names and restore declarations, choices, history, references, non-stream
responses and SSE events without changing tool ownership.
Implement the Claude Code 2.1.220 CCH algorithm over the final serialized
request bytes, align currentDate and first-user cache layout, update the
official beta/header baseline, and use upstream count_tokens for OAuth and
first-party Anthropic credentials.
Match the 2.1.220 TLS ClientHello so the transport fingerprint agrees with the
identity the request now claims, and document the CLI defaults and automatic
OAuth signing / tool alias behaviour in config.example.yaml.
- Updated `NewUtlsHTTPClient` to support context-aware RoundTrippers for protected hosts (e.g., Cloudflare bypass).
- Replaced `anthropicHosts` with `utlsProtectedHosts` to generalize host handling logic.
- Added unit test to validate context-based RoundTripper behavior.
- Replaced `NewProxyAwareHTTPClient` with `NewUtlsHTTPClient` in relevant executors for improved TLS fingerprinting.
Closes: #3680
- Updated all references from v6 to v7 for `github.com/router-for-me/CLIProxyAPI`.
- Ensured consistency in imports within core libraries, tests, and integration tests.
- Added missing tests for new features in Redis Protocol integration.
