Some checks failed
Workspace operators set 'provider: minimax' in /configs/config.yaml expecting the adapter to route to MiniMax. Pre-fix behavior: adapter ignored 'provider:' entirely, _resolve_provider model-matched against _BUILTIN_PROVIDERS (anthropic-oauth + anthropic-api only), no model_prefix matched 'MiniMax-M2.7-highspeed', silent fallback to providers[0] (anthropic-oauth) — SDK kept using CLAUDE_CODE_OAUTH_TOKEN, hit OAuth quota under a name the operator never asked for. Fix: _resolve_provider now takes an explicit_provider arg. setup() reads it from runtime_config.provider OR top-level config.yaml provider:. Explicit name in registry → returned. Not in registry → ValueError with the two paths to fix (add provider entry, or switch runtime template). 10 new tests cover: explicit-in-registry returns match, case-insensitive, not-in-registry raises with actionable message, defense-in-depth against silent fallback regression, custom-registry lookup, empty/None treated as no-explicit (back-compat). Closes #180. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
