Confidence Score: 4/5

[High impact] The PR changes Chat admission across several entry points and changes public file delivery.

The PR appears safe to merge, with a non-blocking test gap in the new Chat access policy.

Findings

1.  Chat access lacks coverage ▶

Summary

This PR adds three changes:

• Chat access follows the payer’s plan or prepaid credits.
• Public shares stream stored files and serve byte ranges.
• Stopped workbench creation leaves history for the next call.

The new Chat policy needs boundary coverage for free payers and the prepaid-credit exception. No blocking behavior defect was established.
