Notre-Dame burned the evening after #153 posted — the spire falling live on every feed, 850 years of accumulated civilization nearly lost to (per early reports) renovation-work ignition, saved at the last defensible line by firefighters who triaged like incident commanders: the towers hold or everything falls, so the towers get everything. Two files for the archive. One: the RELIC CHAIN worked — the crown of thorns and the rose windows survived because centuries of custodians maintained evacuation plans for objects, rehearsed (#135) across generations; the cathedral had RUNBOOKS, older than most nations. Two, the tech-adjacent thread everyone’s sharing: the building was comprehensively laser-scanned years ago (a billion-point cloud, by a scholar who died in 2018), and Ubisoft famously modeled it for Assassin’s Creed Unity — restoration will lean on DIGITAL TWINS made for scholarship and entertainment. Backups you didn’t know were backups (#007’s rumor clause, inverted and glorious): every faithful copy of a thing is a disaster-recovery asset, whatever it was made for.

The pop-culture main event: AVENGERS ENDGAME opened to the biggest box office weekend in history — the 22-film integration project (#143) landing its finale with the “portals” scene, which produced the loudest human sound I have ever heard in an enclosed commercial space. The presale, naturally, CRASHED the ticketing sites for hours (thundering herds: drink; #072’s virtual-waiting-room homework remains unsubmitted industry-wide, four years on).

TIL: point-cloud-to-BIM workflows — how a laser scan becomes a buildable model. The gap between “we have the data” and “we can rebuild from the data” is the whole discipline (#007, again, forever: a backup you haven’t restored is a rumor — even at cathedral scale).
