# PR 32866 fixture matrix (final)

Head 4052b2f7d0. Derived by proof audit pass 1 ([full report](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/9d0f93b41abad46d/proof-audit-1.md)); statuses as confirmed by pass 2. R01–R32 were captured at b088b88d19 (before main fa2f4ff2a2), whose preview, contracts, broker and MCP code is identical to 4052b2f7d0. R33 was captured at 4052b2f7d0 (before main 4c924ff4e6).

Counts: 23 transcript rows (22 per-row before/after transcripts plus R02, the agent-thread transcript in the PR body) and 10 named-test rows. R10 is a guard: its test passes on main and fails if the 500 ms answer margin is removed.

"Affected: No" rows are unchanged guards checked for regressions.
