OpenCode Zen and Go are mixed-API-surface providers — different models
behind them use different API surfaces (GPT on Zen uses codex_responses,
Claude on Zen uses anthropic_messages, MiniMax on Go uses
anthropic_messages, GLM/Kimi on Go use chat_completions).
Changes:
- Add normalize_opencode_model_id() and opencode_model_api_mode() to
models.py for model ID normalization and API surface routing
- Add _provider_supports_explicit_api_mode() to runtime_provider.py
to prevent stale api_mode from leaking across provider switches
- Wire opencode routing into all three api_mode resolution paths:
pool entry, api_key provider, and explicit runtime
- Add api_mode field to ModelSwitchResult for propagation through the
switch pipeline
- Consolidate _PROVIDER_MODELS from main.py into models.py (single
source of truth, eliminates duplicate dict)
- Add opencode normalization to setup wizard and model picker flows
- Add opencode block to _normalize_model_for_provider in CLI
- Add opencode-zen/go fallback model lists to setup.py
Tests: 160 targeted tests pass (26 new tests covering normalization,
api_mode routing per provider/model, persistence, and setup wizard
normalization).
