Reason: Add a MiniMax provider preset with selectable global and China API compatibility endpoints.

Changes:

  • Add MiniMax to the LLxprt provider configuration with MiniMax-M3 as the default model.
  • Let users select the API compatibility mode and region, deriving the matching endpoint URL.
  • Route MiniMax sessions through the matching LLxprt provider environment and base URL.

Checks:

  • pnpm lint:ci
  • pnpm build
  • cargo fmt --all -- --check
  • cargo check -p backend --lib
  • cargo clippy -p backend --lib -- -D warnings
  • Secret scan passed.

Test note:

  • cargo test -p backend test_session_environment_llxprt_minimax_endpoints --lib is blocked by existing test-only compile errors for missing RequestToolCallConfirmationResult and mask_api_key; the same errors reproduced before this patch.

Summary by CodeRabbit

  • New Features
    • Added MiniMax as a supported provider, with global and China regions and OpenAI-compatible or Anthropic-compatible API formats.
    • MiniMax settings automatically select the matching endpoint and default model.
  • Updates
    • LLxprt credentials are now scoped to the launched session. Unconfigured endpoints no longer inherit certain endpoint settings from the parent environment.
    • Updated the default Gemini model to Gemini 3.1 Pro Preview.

📝 Walkthrough

Walkthrough

MiniMax support was added to LLxprt settings and request configuration. The frontend resolves endpoints from region and API format. The backend maps provider aliases and applies session-scoped environment values to child commands.

Changes

LLxprt provider support

A rabbit checks the endpoint map,
Then sets the region with a tap.
The child command gets keys in place,
While parent vars keep their space.
MiniMax hops into the flow,
And Gemini models glow.

In `@crates/backend/src/session/mod.rs`:
- Around line 68-78: Update SessionEnvironment::setup_llxprt and the session
launch flow so provider credentials and endpoints are applied directly to each
child Command via .env(...), rather than through process-global EnvVarGuard
mutations. Ensure initialize_session passes the session-specific OPENAI_* or
ANTHROPIC_* values through to cmd.spawn(), including MiniMax configurations,
without changing the existing provider selection behavior.

In `@frontend/src/components/common/SettingsDialog.tsx`:
- Around line 709-785: Update the MiniMax configuration controls in
SettingsDialog to use the component’s existing translation hook and
component-level keys for the “API compatibility”, “Region”, “Endpoint URL”,
“OpenAI-compatible”, “Anthropic-compatible”, “Global”, and “China (CN)” labels.
Add the corresponding localized entries and render each visible label and
SelectItem text through t(...), preserving the current values and behavior.

In `@frontend/src/types/backend.ts`:
- Around line 44-54: Update isLLxprtConfig to validate optional apiFormat and
region values against the LLxprtApiFormat and LLxprtRegion unions before
returning true. Accept absent fields and only the supported values, rejecting
invalid persisted values so getMiniMaxEndpoint does not process malformed
configurations as LLxprtConfig.

🟡 Minor · Add an accessible name to the Gemini model selector. · SettingsDialog.tsx:420

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Add an accessible name to the Gemini model selector.

The visible model label is not associated with SelectTrigger. Screen readers can announce an unlabeled selector. Add aria-label={t("conversations.model")} to this trigger, or connect it to the label with aria-labelledby.

The backend test build failed to compile because three tests referenced
code removed in earlier refactors:

- test_api_key_never_logged_in_mask called mask_api_key, removed in Piebald-AI#155
- test_llxprt_rejects_invalid_base_url and test_qwen_rejects_invalid_base_url
  asserted a "private IP" error from URL validation, also removed in Piebald-AI#155
- test_request_tool_call_confirmation_result_serialization used
  RequestToolCallConfirmationResult, removed in Piebald-AI#159

These tested behavior that was deliberately removed, so delete them
rather than restore the code. This allows `cargo test -p backend` to
compile again.
- Apply LLxprt credentials to the child process with Command::env instead
  of process-global std::env::set_var. Concurrent sessions sharing
  variable names such as OPENAI_API_KEY could previously overwrite each
  other's keys and endpoints between setup and spawn. Qwen and Gemini
  still use EnvVarGuard and will be migrated separately.
- Validate apiFormat and region in isLLxprtConfig so invalid persisted
  values are rejected instead of silently falling back to the global
  OpenAI endpoint.
- Localize the MiniMax settings controls in all four locales.
- Give the Gemini model selector an accessible name.

Rewrite the LLxprt environment tests to assert session-scoped values and
that nothing leaks into the parent environment, including a test where
two sessions set the same variable with different values.

for HTTPS except localhost in development, allowed HTTP/HTTPS schemes, private
IPs, cloud metadata endpoints, and the 500-character limit; restore tests for
both invalid-URL cases. In initialize_session, invoke LLxprt without a shell and
pass the executable, provider, model, and base URL as separate arguments so
configuration is not interpolated into a command string.

OPENAI_BASE_URL and ANTHROPIC_BASE_URL before applying session variables,
preserving either endpoint when explicitly present in self.vars. Enable this
cleanup only for LLxprt child processes at the call site; keep Qwen’s
process-level OPENAI_BASE_URL behavior unchanged.

Comment thread crates/backend/src/session/mod.rs
SessionEnvironment::apply_to only added variables, so an LLxprt session
without a configured base URL inherited OPENAI_BASE_URL or
ANTHROPIC_BASE_URL from the parent environment. That inherited endpoint
could redirect the session's API key to a server the user did not
configure.

LLxprt sessions now remove both endpoint variables from the child
environment before applying session values, so a configured base URL
still takes effect. Qwen and Gemini sessions are unchanged; Qwen still
relies on its process-level OPENAI_BASE_URL.
