Additional Notes

closes #419

[ogazboiz]

hey, main was failing CI from broken auth imports + frontend parse errors. fixed and pushed to main now. please rebase to pick up the fixes:

git fetch upstream
git rebase upstream/main
git push --force-with-lease

if there's a conflict, resolve it locally and we'll review once CI is green.

closing for inactivity — this has been open ~4 weeks with no contributor response after the last review. main has moved significantly since (#499 contract reconciliation, #706 auth-mock fix, ~150 new issues filed). if you want to continue this work, open a fresh PR rebased on current main. happy to review it then.
