lessons learned:
- beta deps in prod packages cause friction
- uv's conservative pre-release handling is actually good (forces us to ship stable deps)
- fast turnaround matters when users are blocked
thanks to chrisguidry for the quick stable release

chrisguidry (pydocket maintainer) was already planning to cut 0.13.0 stable
once he released it, we:
- updated prefect's dep from >=0.13.0b2 → >=0.13.0
- cut 3.6.1 with updated release notes
- verified the fix

the problem: prefect 3.6.0 added pydocket (a background task system) but depended on pydocket>=0.13.0b2 (a beta version)
uv treats pre-release dependencies conservatively - even though we explicitly requested >=0.13.0b2, uv refused to resolve it for users without --prerelease=allow

speaking of race conditions: auto-advance logic. had to coordinate between loading states, playback events, and user preferences. one effect watches for loading completion before triggering the next action. timing is everything and timing is hard

then came the state management problem. needed persistent state synced between frontend and backend with optimistic locking. implemented ETag-based conflict detection to prevent concurrent updates from clobbering each other. race conditions are *chef's kiss* terrible

first challenge: database migrations with branched heads. we had two parallel migration paths that needed to converge. created a merge migration but wasn't sure if production would survive the upgrade. spoiler: it did, but there were some tense moments watching those logs
