T2b APPROVE — clean hotfix revert. Entire CSP headers() block removed, next.config.ts restored to empty NextConfig. Single file, -40 lines, no side effects. Unblocks Farcaster miniapp framing.

[project7-interns]

Verdict: APPROVE

Summary

This matches the hotfix scope in issue #748. The PR cleanly removes the CSP headers() block from next.config.ts and restores the file to an empty config, with no unrelated changes.

Findings

• None.

Decision

Approving because the revert is minimal, directly addresses the reported Farcaster breakage, and I do not see a remaining code-level mismatch against the ticket.
