Challenge Countdowns · Hackathon Deadlines
The Gantt timeline and the swimlanes below draw only the recorded instants. Every countdown on this page is computed in your browser, every second, from the deadline instants recorded in the challenge entries log. This page consumes data/challenge-countdowns-feed.json (schema challenge-countdowns-feed/v1, contract docs/ops/CHALLENGE-COUNTDOWNS-FEED.md) and nothing else — the feed holds instants only, never a pre-computed remaining time, and an instant the log does not record shows as not recorded rather than anything guessed.

Lanes group the same recorded entries by live state. Further lanes (stage pipelines, queues, blocker chains) join this board when their records exist as feeds — nothing is drawn from prose.
