Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

This PR replaces string-based require(...) revert reasons with a shared custom-error vocabulary (AgentPayErrors) and updates tests/gas snapshots accordingly.

Changes:

• Introduces src/lib/AgentPayErrors.sol and updates contracts/libraries to use custom errors instead of revert strings.
• Updates Foundry tests to assert on custom-error selectors / full error payloads.
• Refreshes gas measurement snapshot files to match the new bytecode/error behavior.
