OAuth 401 regression: oauth-2025-04-20 beta not injected when context1m set via model headers
증상
When the Anthropic API key is an OAuth token (sk-ant-oat-*), requests fail with HTTP 401 if context-1m-2025-08-07 is configured via model-level headers rather than via agent extra params (context1m: true). The oauth-2025-04-20 beta header is never injected, causing Anthropic to reject the Bearer auth.
원인
Authentication credential mismatch, expiry, or permission scope gap between the requesting agent and the target API.
해결법
Move context-1m from model-level headers to agent extra params:
// Remove from models.providers.anthropic.models[].headers
// Add to agents.defaults.models:
"anthropic/claude-opus-4-6": {
"params": { "context1m": true, "cacheRetention": "short" }
}
