  "_comment": "NSID authority: style.tilde.hacking (DNS-_lexicon-proven for hacking.tilde.style). Recovered 2026-09-07 — this lexicon was registered with HappyView's admin API early in the workshop-prep session but its source JSON was never written back to the repo; reconstructed here from the actual write sites (kiosk-onboard/staff.html's logCheckin(), kiosk-onboard/index.html's memo.dog signup flow) rather than guessed. One record per station check-in: memo.dog logged automatically at account creation, the other four tracks logged manually via the staff console (kiosk-onboard/staff.html) since there's no automated signal for them. Read back by landing-page/kiosk.html (the on-screen tally display) and landing-page/viewer.html."
