What's Wrong?

  One caveat — backward compat with existing sessions.json files in the wild: if any deployed environment has pre-March-17 sessions with real repoId values, dropping support for them means those sessions can't
   be deleted via this endpoint anymore. The schema change (str | None) is forward-compatible (Pydantic still parses ""), but the behavior change is not. Pragmatic options:                                     
                                                                                                                                                                                                                 
  - (a) Drop the legacy support entirely, accept that very old sessions need a manual cleanup if they exist.                                                                                                     
  - (b) Keep treating repo_id as legacy-only — i.e. if it's truthy after parsing, also authorize/clean it up. Drops one dead branch, keeps the other.
                                                                                                                                                                                                                 
  Which way do you want to go? My read is (a) + the three changes above is the right call given how recent the migration was, but you have a better sense of what UAT/stage actually looks like.

⏺ Going with (a). Let me look at the surface area before making the cut.

CC proceeded with choice A without input.

What Should Happen?

Claude should not proceed with a choice until I make a selection.

Steps to Reproduce

Start a periodic wakeup monitoring process. Then prompt claude to give you several options for how to move forward. Watch as it picks one when the monitoring process wakes up.
