Summary
When a developer squashes multiple commits into one (e.g., via git merge --squash or interactive rebase), intermediate commits can inflate agent attribution. The final squashed commit contains only the net changes, but attribution may be calculated against accumulated intermediate diffs.
What to implement
Ensure attribution is calculated against the actual diff of the final commit (parent-to-commit), not accumulated from intermediate commits. When the post-commit hook runs after a squash, it should compare the committed tree against its direct parent only.
Context
internal/attribution/ — attribution calculation logicinternal/hooks/postcommit.go — post-commit hook that triggers attributioninternal/session/ — session state that may carry intermediate attribution data
Why
Squash workflows are common in teams that use feature branches. Inflated attribution makes the agent appear responsible for more code than it actually wrote, undermining the accuracy of the audit trail that Partio provides.
