Ayaan's 28e4cd81a9 (#70863, thanks @bidadh, source from Arthur Kazemi
8abbae0101) extended params.context1m:true so the configured 1M
context window override now applies to eligible Claude CLI Opus and
Sonnet models, not only direct API calls. CHANGELOG entry covered
the change but docs/providers/anthropic.md '1M context window (beta)'
Accordion only described direct-API behavior, so Claude CLI users had
no signal the same param works for their backend. Add a sentence
inside the same Accordion.
