Shared cached-LLM narration: return cached prose if the entity is unchanged, else generate (async, off the sim loop), cache it, and return. Gr

A city's history, generated deterministically from simulation truth: its founding, the recorded events that named it, and its present conditio

Validate an untrusted dict into a config, merged onto `base` (or defaults). Raises ValueError on unknown keys or wrong types; numeric fields

Stable [0,1) hash — same idea as projection._stable_float.

Nudge a knob by a percentage of its current value, clamped.

Stamp an archetype's identity onto a civilization (used at genesis and when a successor inherits a parent's character before it drifts).

Phase 2 — an explorable family: parents, spouse, siblings, children, with living/dead status and ids to jump to. Lazy — only pool members are

Reset a single subsystem. Terrain underpins everything → full rebuild; the others re-seed in place (with a full-rebuild fallback on error).

json.dumps with strict mode — raises ValueError on NaN/Inf, TypeError on non-native types. The thing every payload must survive.

Summed-octave value noise in roughly [-1, 1].

A cheap deterministic signature of the generated world.

A chronological life story drawn entirely from the person's own memories and recorded state — birth, marriages, children, migrations, faith, d

Cities (rich), civilizations, and trade routes. Medium-rate channel. All positions normalized 0..1 so the client is resolution-independent.
