Field notes
Korea custody habits worth noting
Devlink Core runs office hours from Jongro-gu, Seoul. Across cohorts, a few habits show up often enough to mention — not as universal truths, but as patterns worth testing against your own Cold Wallet Audit Board.
Sealed sessions after core hours
Several desks prefer late-evening windows when open-office traffic drops. That helps privacy, yet it also shrinks the witness pool. Boards that fail usually skipped naming a backup witness before the primary left for the day.
Bilingual column headers
Teams mixing Korean and English notes benefit from fixed bilingual headers. Free-form switching mid-row creates ambiguity about whether a cell was verified or merely translated.
Holiday calendars as blockers
National holidays and company shutdown weeks should appear as open questions weeks ahead: “Signer B unavailable 5–9 Oct — reschedule sealed window.” Treating holidays as surprises is how dual-control quietly collapses.
