### Timebox overrun

## Schedule constraints

- ✅ JSC cannot be present on Tuesday, September 13 on 10–11 am GMT+9 (6–7 pm PDT).
- ✅ Axel Rauschmayer: If possible, I’d like to start as early as possible (any of the 4 days is OK). Later times would be challenging, due to the time difference with Europe.
- ✅ Nicolò Ribaudo will not be available on Friday, and wants to be present for "Refactor of import-related Host Hooks" and "Record & Tuple".
- ✅ Robin Ricard will only be available during the second slots every day: 13:00 to 15:00 JST
- ✅ Patrick Soquet will only be available during the second slots every day: 13:00 to 15:00 JST. Patrick wants to be present for "Refactor of import-related Host Hooks" and "Record & Tuple".
- ✅ Mathieu Hofman will only be available during the first slot of every day: 10:00 to 12:00 JST, and would like to be present for "Explicit Resource Management"
- ✅ Philip Chimento unavailable during Day 3 and the first slot of Day 2. Second slot of Day 2 is OK but not preferred. Must be present for "Temporal update" and would prefer to be present for "Intl.DurationFormat" and both iterator helpers items.

## Key

- ⏳ : late addition for stage advancement and schedule prioritization
