Bug Fixer

The implementation counterpart to arc-bug-finder. Where the finder researches and files a bug, the fixer reviews, resolves, and ships it.

The input is a filed bug ticket; the output is a merged-ready PR that closes that ticket, with the ticket updated to reflect the resolution.

This skill modifies product code — but only after it has independently confirmed the bug is real and the cited root cause is correct. A ticket is a hypothesis, not a work order.
