The National Disaster-Warning Case Study on heain-core The Earthquake of 28 March 2025 and the Collapsed Building Replaying the Real Event on a 34-Node Simulation, from the First Minute through 45 Days of Rescue to the Prosecutor: with Core Round C6

Abstract The Sagaing Fault earthquake in Myanmar on 28 March 2025 brought down a high-rise under construction in Bangkok's Chatuchak district at 13:20. DDPM's warning went out 82 minutes later, as SMS in rounds [7]. The count of the missing moved between 81 and 117: there was no central list of who was on site, and the site office's records were destroyed with the building [8]. People reported 14,430 cracked buildings in 72 hours [10], and the case reached the prosecutor on 22 July 2026 [8]. This Volume 7 of the case study [1] reports the replay of this event (series E3). The author replayed the event on three time scales (1 hour = 1 minute for the first 3 days, 1 day = 1 minute for the rescue, 1 month = 1 minute for the case) on a 34-node layout with gate-log Micro Nodes at two sites and a building-inspection unit, in two runs: "as it happened" and "with HEAIN". Requirements R19–R27 test the first minute, conflicting sources, records that must survive a destroyed machine, the count of the missing, temporary approvers, public reports and case evidence. The first run on core C5 found the two expected gaps: 4 gate entries were lost with the site's machine, acknowledged before the office had them, and a foreign team's approver right did not end when the team left. Core C6 (f6c46ec) added acknowledgement once the parent has an entry (durability parent) and approver rights that expire (roles.approver_expiry). After the fix the HEAIN run passed 26 of 26 checks with no gap. The first CAP went out in the event's 2nd minute instead of the 85th; all 160 gate entries reached the office with no name lost; the count of the missing matched the simulation's truth at every point; unsafe buildings were closed 0.1 hours after the first report once an engineer confirmed, instead of 26.6; and all 8 case records were kept.
