Run 10: organic recovery achieved - minerals are not a commons

Recovery blocker was material, not motivational. Two fixes: (1) harvest
floors and commons debris apply only to living, regenerating resources -
stone does not regrow, so "leave half" merely stranded the world supply
and kept the homeless homeless forever; minerals now quarry to depletion
for every soul equally. (2) Matter conservation: idle variety-gathering
touches only renewables, and packs may only shed what the land replaces
- lossy make-room had milled 900+ stone to dust during demand flapping.

Verified over 260 headless days: year-1 winter still wrecks the naive
town, it rebuilds in 20 days, famine survivors found the first granaries
from hunger memory, and year-2 winter passes with zero ruins on stored
reserves. The town has a history now: naive youth, catastrophe,
learning, resilient maturity.

Remaining tuning in FINDINGS.md: granary sprawl, post-famine nourishment.

+## Run 10 — The mineral question: recovery achieved
+
+Demand diagnostics found the recovery blocker was *material*, not
+motivational: homeless villagers correctly demanded stone (462/525
+villager-days) but could not get it, twice over:
+
+1. **The commons ethic stranded the stone.** Respectful souls won't take
+   the last half of any deposit — but stone doesn't regrow, so once all
+   deposits sat at the floor, the world's remaining stone was morally
+   untouchable and the homeless stayed homeless forever. *Fix: the
+   harvest floor is an ethic of regrowth — floors and commons debris now
+   apply only to living, regenerating resources. Minerals quarry to
+   depletion, for every soul equally.*
+2. **Lossy packs milled the mountains to dust.** Idle variety-gathering
+   mined stone as busywork, and the make-room rule vaporized cargo on
+   every demand flap — 900+ stone destroyed in packs. *Fix: idle
+   gathering touches only what regrows, and packs may only shed what the
+   land replaces. Minerals are mined on purpose and conserved.*
+
+**Verified (260-day headless run):** year-1 winter still wrecks the naive
+town — then it rebuilds within 20 days, the famine survivors found the
+first granaries (memory, as designed), storage grows through autumn, and
+**year-2 winter passes with zero ruins** on granary reserves. The town
+now has a history: naive youth, catastrophe, learning, resilient
+maturity. Organic civilization works end-to-end.
+
+Remaining tuning (non-blocking): granary sprawl (hunger-scarred souls
+keep founding storage — ~10 granaries by day 200; needs a satiation
+rule), and chronically low average nourishment in the post-famine years
+(likely endless granary-stocking labor crowding out comfort — related to
+sprawl).
