R-224: a body at zero absorbed damage for free

Hit points clamp at zero, so further damage to somebody already there changed
nothing — and a STABILISED agent absorbed it forever, because the count was held
and there was nothing else left to move. You could empty a magazine into someone
bleeding out and the system would not notice.

Damage at zero now breaks the stabilisation and costs a round of the count, and
hitLocationRoll calls died() when that meets the limit.

Found by playing LOW VERGE until it killed somebody: two agents who were
medically stable died in the water on a failed tidal extraction.

+## LOW VERGE — played until it killed somebody
+
+Field Lead, Physician, Recording Officer, Translation Officer at a boarding school out
+of term. The brief did its new job: Where, When, the job, what to expect, and the way
+back, all before the prose. Four phases.
+
+The rival desk never became a fight — the Field Lead rolled a natural 1 on Status 15%
+and they stood down, which is the leverage the Opposition page names. The danger was
+never them. The Pressure page had already declared the price: *"There is a body that
+has to be carried, and it is one of ours."*
+
+Two phases failed, the Containment phase failed, and the other side's weather came
+through a gap at the true scale. Three of the four went to zero in a single exposure
+and the Physician — 48% First Aid, on four hit points herself — stabilised all three,
+one after another, and then did it again after the next wave.
+
+Then the extraction failed on a tidal causeway with the window already past. Marek
+Achterberg and Tomas Vance died in the water, both at Coherence 10, both **recorded
+properly — a death in service, a form, a pension, a name that stays where it was put.**
+Nkechi Quist came home stable at zero. Ambaro Vance walked off the causeway on four
+hit points having kept three people alive for six rounds and lost two of them anyway.
+
+**R-224 · a body at zero absorbed damage for free.** Found by this play-through and it
+is what killed them. Hit points clamp at zero, so further damage to somebody already
+there changed nothing — and a STABILISED agent absorbed it forever, because the count
+was held and there was nothing else left to move. You could empty a magazine into
+someone bleeding out on the floor and the system would not notice. Damage at zero now
+breaks the stabilisation and costs a round of the count, and `hitLocationRoll` calls
+`died()` directly when that meets the limit. That is precisely how the causeway killed
+two people who were medically stable four minutes earlier.
+
+**Worth noting for the Last Entry table:** both died at Coherence 10 and so got the
+dullest of the four entries. Coherence is normally spent on the way home, and these
+two never got there — an agent who dies mid-case is likely to be *well* filed. The
+interesting entries belong to people who die after a bad crossing, which is the right
+way round but means the table's bottom half will be rarer than its top.
