roadmap: capture the expanded substance + warden-personality vision

Foul Play "finish substances" grew into a substance-cocktail system, staged so
each ships green:
- Hooch: fermentable, incendiary flame-splash firebomb (no splash-code change --
  just a flame damageDef through the existing GenExplosion path), also drinkable.
- Ferment in ANY liquid-holding furniture (toilet, barrel, tub, sink, vat),
  capability-detected by recognizable identity + known vanilla defs, no DBH
  dependency. Hooch requires a site; piss can use one but still brews from body.
- Mixing: a vessel's contents become a runtime blend of SubstanceDefs and the
  splash applies all effects together; defaults to the single substance unmixed.

Contraband warden-personality/corruption (queued under Discipline): search
intensity by trait + circumstance, per-warden item forgiveness, and bent wardens
who smuggle contraband IN -- the corruption supply route that feeds a gang.

+    "a bent warden"). This is the corruption payoff and the thing that feeds a Gang's network.

+  Self-complete (reads vanilla traits/mood/relationships); no dependency. This is where the

+### Foul Play — substance system, expanded (2026-07-15)
+
+The chosen "finish substances" work grew into a full **substance-cocktail** system. Three parts,
+built on the existing `SubstanceDef` (data) + `CompVessel` (delivery) + `CompFerment` split:
+
+- **Hooch.** A fermentable substance whose harm is **incendiary** — set its `damageDef` to a flame
+  def and the framework's own `GenExplosion` splash starts fires (a Molotov), no splash-code change.
+  Fermentation makes a *ripe* (high-alcohol) hooch a stronger firebomb — the harm-vs-time axis, but
+  running the other way. Also **drinkable** as alcohol (share vanilla `Chemical_Alcohol` if cheap).
+- **Ferment in any liquid-holding furniture, not just toilets.** Generalise to a capability: a
+  fermentation SITE is any *building that can hold liquid* — a DBH toilet/tub/sink, a vanilla
+  `FermentingBarrel`, a modded vat. Detected by recognizable identity (defName/label vocabulary:
+  toilet, barrel, tub, sink, tank, vat, trough, cistern, latrine, urinal, basin) + known vanilla
+  defs, **dependency-free**. Hooch *requires* a site (pruno needs a vessel); piss can *use* one for a
+  bigger/faster batch but still brews from the body. Fits Foul Play's standing "works with all
+  containers" rule.
+- **Mixing — combine any substances.** A vessel's contents become a **blend** of `SubstanceDef`s
+  (piss + feces + semen + …), and `SubstanceSplash` applies each one's effects together — caustic +
+  disease + humiliation in one throw. "Mix everything": the blend is a runtime list on the vessel,
+  defaulting to the def's single substance when unmixed, so every existing vessel still works.
+
+Staged so each ships green: **hooch → liquid-container fermentation → mixing.** The vessel data model
+is built mixture-capable and site-aware from the start so none of it is a later refactor.
