Next review available in: 18 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 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.

In `@src/analyzers/deepseek_harness.rs`:
- Around line 184-188: Replace the Utc::now fallback in event_date with a stable
timestamp supplied by the session parser. Track the most recent valid event
timestamp in parse_session_reader and pass it as the fallback, using the file
modification time when no prior event timestamp exists.
- Around line 380-383: Update parse_deepseek_harness_file and the underlying
parse_session_reader flow so an incomplete final zstd frame returns the messages
accumulated before the read error instead of discarding them, while preserving
normal error propagation for other failures and relying on the decoder’s
existing concatenated-frame support.

Summary
Add DeepSeek Harness usage tracking from compressed local session logs. The analyzer reports direct user messages, model token usage and costs, cache and reasoning tokens, tool activity, and session metadata.
