- Only preserve OpenRouter dot-delimited router suffixes when the upstream baseURL is openrouter.ai / *.openrouter.ai
- Strip RouterSuffix down to the native GPT/Grok/Meta envelope when forwarding to official tokens (chatgpt.com, api.openai.com, api.x.ai) or non-OpenRouter third-party providers (while keeping native api.meta.ai fail-closed against cross-caller envelopes)
- Strip RouterSuffix before storing GPT signatures in the Codex reasoning replay cache
- Gate MetaExecutor signature sanitization by baseURL so custom/third-party meta-api-key endpoints replay router-suffixed Meta Muse envelopes while native api.meta.ai stays native-only
- Pass resolved target model (with requested-model fallback for aliased deployments) through Codex, Codex WebSocket, and OpenAI-compat Responses sanitization paths
- Broaden Meta Muse model-id boundary matching (muse, meta/muse, muse_*, meta-muse-*) and allow Meta envelopes in the Codex reasoning replay cache
- Reuse CodexReplaySignatureForTarget in Claude-to-Codex request translation and avoid duplicating streamed thought summaries on Interactions reasoning done events
- Removed deprecated interceptor and executor-related methods, including `callRequestInterceptor`, `callResponseInterceptor`, and `callStreamChunkInterceptor`.
- Consolidated unused logic and pruned redundant imports to streamline `adapters.go`.
- No functional changes.
