Fix an amplifier-agent Bug

Bug

$ARGUMENTS

If that is empty, ask what is broken. Get the exact code or request that failed and the exact output, not a paraphrase.

The Method

A bug is a contract that was violated or under-specified. The fix is working code plus coverage that stops this class of bug from recurring silently.

Fixing stays frozen until the root cause is pinned.
Tests and rubrics are never edited to make a fix pass.
