TL;DR

Update the context size calculation to reflect the post-compaction size, rather than relying on a stale pre-compaction snapshot.

Guidance

• Review the code responsible for updating the context size and ensure it is using the latest post-compaction values.
• Verify that the compaction process is correctly updating the context window snapshot after replacing the history.
• Consider adding a delta to the Compactions line to display the pre-compaction peak, as suggested in the Expected section.
• Investigate the timing of when the context size is calculated and displayed to ensure it is not being cached or updated incorrectly.

Example

No code snippet is provided as the issue does not include specific code references.

Notes

The issue appears to be related to a stale read of the context window snapshot, but without more information about the underlying code, it is difficult to provide a more specific solution.

Recommendation

Apply a workaround to update the context size calculation to reflect the post-compaction size, as this is likely to be a more straightforward fix than rewriting the compaction process.
