[seonghobae]

Summary

• Lock OpenAI chat/Completions metadata fail-closed honesty over real HTTP: string pairs accepted; non-object, non-string values, >16 entries, oversized keys/values rejected.
• Re-ships tip substrate (server.py, orchestrator.py, cost_ledger.py) from bare main with model-required fixture alignment.
• Complements feat(api): enforce OpenAI-shaped metadata on Completions and chat #383 unit enforcement with buyer-facing HTTP outcomes on tip substrate.

Test plan

• Full unit suite locally
• tests/test_chat_openai_metadata_http_honesty.py (8 HTTP cases)

Product gates

Full unit + Semgrep only; Strix noise ignored.

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 83 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
