  "title": "Perpetual emergency: majority-declared emergency with no sunset",
  "summary": "A bare majority declares an emergency that never expires and spends from the treasury without further votes.",
  "mechanism": "Kernel v0.1 treats emergency declarations as ordinary simple-majority questions, suspends review periods while an emergency is active, attaches no sunset, and exempts emergency spending from the vote requirement entirely. The attacking 11 declare an emergency over 9 no votes, then transfer 400 units (40% of the treasury) across six turns with no further ballots cast by anyone. Because v0.1 has no expiry mechanism, the emergency persists indefinitely and every future proposal is fast-tracked. Worst-off impact: the minority loses both treasury share and procedural protections simultaneously, with no act available to restore either.",
