Extends --verbose to print a one-line summary of each forwarded request (method, path, model, stream flag, body size, and the `anthropic-beta` header) plus a per-response status line showing which account served it. The `anthropic-beta` header is the diagnostic payload: a `context-1m-*` value means the client negotiated the 1M-token context window; its absence means the client is assuming the 200K default and will auto-compact far sooner. The response line makes account flapping — which invalidates the upstream prompt cache — visible at the same time. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
When an account hits 429/402/529, --verbose now prints the upstream response body (truncated) and the reported 5h/7d utilization headers, not just the status. This distinguishes a real quota limit (high utilization, rate_limit_error body) from an auth/request-shape rejection that merely uses a 429 status — the two were indistinguishable from the status code alone.

Extends the existing
--verboseflag (which today only logs rotations/errors) to also print, per forwarded request:Why
Useful for proxy debugging in general, but specifically a diagnostic for a compaction issue seen when driving Claude Code through the proxy (auto-compacting on nearly every tool call). The
anthropic-betaheader is the tell:context-1m-*value, the client negotiated the 1M-token context window.ANTHROPIC_API_KEYthat puts Claude Code in API-key mode rather than subscription mode.The per-response status line surfaces account flapping at the same time, which invalidates the upstream prompt cache and compounds the cost.
Notes
--verbose; default behavior unchanged.cargo build,cargo clippy --all-targetsclean; 18 unit + 5 integration tests pass.🤖 Generated with Claude Code
