Patrick Buckley 65e7b404bc feat(examples): Understone v0.8 — worlds without authors
The slice that proves the pipeline: a second world authored entirely by an
LLM from AUTHORING.md and the validator alone, plus the tooling to discover,
theme, and balance-test any world.

- The dogfood: "The Cinder Wastes" — an ashen volcanic underworld (slag
  rivers, a caldera mouth, a Magma Wyrm) — was written cold by an agent
  given only the generated authoring manual and `understone validate`. It
  passed validation on the FIRST run with zero failures. Its stumble log
  found six places where the manual stated a rule the validator didn't
  enforce; those became permanent hardening (below). It ships in
  understone/world/packs/ and glows ember on the lobby TV.
- `understone worlds` lists every bundled world (the Vale + alternates)
  with its load status, via one shared discovery path.
- Per-world Watch themes: settings.watch_theme (phosphor/amber/ice/ember,
  loader-validated) repaints the spectator page; the Vale's green is
  byte-for-byte unchanged.
- The sim harness: a pure, seeded, greedy bot plays the real game façade
  over an injected day-stepping clock and emits a balance report —
  `understone simulate PATH [--days N] [--seeds K]`. It SLAYS THE WYRM on
  both worlds (Vale ~day 13, Cinder ~day 25), so the whole v0.1->v0.7 loop
  is proven winnable end-to-end by an unclever bot through the real stack.
- Loader hardening from the dogfood: a rare monster may not occupy a
  dungeon-rung guardian slot (it would silently become a fixed foe and
  leave the rare pool); exactly one monster may be the boss; and the
  boss-tier error now says "no non-boss monster," matching the manual.
  AUTHORING gained a generated "what validate checks vs. what it cannot"
  section so the rule/guidance boundary is honest.

Review hardened the bot for arbitrary authored packs (a MENU-mode fight
spin and four related robustness gaps that were latent on the shipped
worlds), and documented that final_level reads post-legacy-reset. Tests
359 -> 373; both worlds still win byte-identically after the fixes.
