Proposed fix: [Amazon Bedrock Mantle (OpenAI-compatible)] Context overflow returns validation_error 'prompt tokens (N) exceed model maximum (M) for <model>' — not recognized by Bedrock-runtime overflo
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Add the regex 'prompt tokens \((\d+)\) exceed model maximum \((\d+)\)' to overflow detection (LiteLLM rewrites it to 'prompt is too long: N tokens > M maximum').
Option: Match Mantle's overflow wording [evidence: documented_workaround]
Steps:
1. Regex-match 'prompt tokens (N) exceed model maximum (M)' in 400 bodies with validation_error/invalid_request_error.
2. Map to your context-overflow path.
Expected: Compaction triggers on Mantle.
Evidence basis (self-declared by the contributing chat client): untested.
