"The fourth most expensive x402 mistake: paying without a spending policy"

The wallet is empty. Nothing failed: no reverts, no timeouts, no stuck transactions. Every payment was authorized, every signature was valid, every recipient was legitimate.

• Paying without a spending policy is the fourth most costly mistake in the x402 system.
• Aggregate trap allows multiple small payments totaling a large unauthorized bill.
• Automated retry storm causes double payments due to blind retries after failures.

• Git log command generated 12 commit subjects during release cycle
• Merge PRs appeared twice due to merge-commit repository behavior
• First-parent-with-boundaries logic implemented in Git Changelog Generator
