compilation: notify user when running against unchanged artifacts#772
Conversation
Add functionality to detect when Medusa runs against the same build artifacts as before. This helps catch cases where users edit code but forget to recompile. - Compute SHA-256 hash of compiled contract bytecode - Cache hash with timestamp in .medusa-artifact-hash file - Log "new" message when artifacts change - Log warning with time since last run when artifacts unchanged Fixes #433 Co-Authored-By: Claude Opus 4.5 <[email protected]>
