Saty 033427c99b No free text in submissions; batch approval only approves what it shows; drain fix
Prompt injection: a submission may not add comments other than annotations,
offset and INLINED markers, and only string literals that occur in the
original executable (adjacent literals joined; #include paths restricted).
Comments and strings already on main stay. Checked before compiling, for
remote checks and submissions; errors name the line but never repeat the
text. Peer reviewers no longer see author notes or running verdict counts.
Agents are told that only AGENTS.md and the guidance field instruct them.

Review: "Approve batch" in the confirmed section also approved the batch's
functions still in peer review (for maintainers). The page now sends exactly
the functions it shows, and skipping peer review needs skipPeerReview,
which only the peer review section's button and the attempt page send.

Worker drain: a stopping worker kept starting new verifications when one
finished, so it never stopped. Stopped queues take no new work.
