# Katalyst Space x NASA (Swift Observatory Boost) revision history

Append-only Arc G field-change log. Forward-only honesty: events accrue from Arc G adoption.

Partnership: [Katalyst Space x NASA (Swift Observatory Boost)](/partnerships/katalyst-space-x-nasa-swift-observatory-boost.md)

## Recorded posture

- First recorded event: 2025-09-01
- Last material change: 2025-09-01
- Material event count: 1
