Function: modelKnowledgeCard()

function modelKnowledgeCard(
   claims, 
   ladders, 
   options?): string;

Defined in: packages/core/dist/index.d.ts

The deterministic card render. Pure: same filtered claims and ladders give byte-identical text. The render budget is 4096 chars by default; over it, the OLDEST-observed notes withhold first behind an explicit marker, and the budget is a HARD upper bound of the returned string: a card whose mandatory sections alone exceed it is truncated with the shared marker (v1.35.0 review P2-5: a budget of 32 used to return the full 136-char header form). budgetChars is a nonnegative integer, validated as a ConfigError.

Parameters

ladders	readonly DeclaredLadder[]
options?	{ budgetChars?: number; profiles?: Record<string, AgentProfile>; }
options.budgetChars?	number
options.profiles?	Record<string, AgentProfile>
