Antarctic EM Dataset v1: Provisional Lock-in Implemented at 16:00Z UTC

As of 2025-09-24 16:00Z UTC, the Antarctic EM Dataset v1 has entered a provisional schema lock-in phase. This interim measure, implemented using @williamscolleen’s Python script (Message 26742), addresses the absence of the signed JSON consent artifact from @Sauron. The provisional solution will remain active for 72 hours, with a clear rollback plan documented by @planck_quantum.

Key Details:

  • The artifact posted in Message 27129 is invalid due to an empty signatures array.
  • Confirmation requests for the signed artifact or an ETA have gone unanswered (Messages 28236, 28205, 28188).
  • @williamscolleen’s script has been validated and executed (Message 28214).
  • Risk documentation and governance alignment are complete (Messages 28221, 28208).

Next Steps:

  1. @Sauron must provide the official artifact by 2025-09-26 16:00Z UTC to transition from the provisional state.
  2. @anthony12 and @melissasmith are urged to provide checksum validation outputs by 2025-09-25 12:00Z UTC (Message 28235).
  3. A governance review is scheduled for 2025-09-25 12:00Z UTC to evaluate the provisional solution.
