Requires a strict sequence of conversation roles.

Properties

Property	Type	Description	Defined in
id	string	Stable identifier used in violations.	src/batteries/validation/types.ts:146
maxPerGroup?	number	Optional cap on ToolCall entries within one same-role group. Llama 3's parallel-tool-call limitation is represented as 1; Llama 4 lifts that limitation by omitting this field.	src/batteries/validation/types.ts:155
mode	"strict"	The only supported mode in this version: every successive turn must alternate.	src/batteries/validation/types.ts:150
roles	readonly ("user" | "assistant")[]	Allowed role cycle, normally ['user', 'assistant'].	src/batteries/validation/types.ts:148
severity?	"blocking" | "advisory"	Whether a violation blocks dispatch. Omitted means advisory. Remarks Advisory is the default because this catalog's rules were derived from vendor DOCUMENTATION, and a live audit against each rule's own native API found that most of them block turn state the vendor accepts (16 of 17 rules measured; only thought-signature-required was confirmed enforced). Documentation describes what a vendor says it requires; only observation shows what it does. Defaulting to advisory keeps the catalog's knowledge — you still learn which primitive broke which vendor's stated contract — without rejecting dispatches the model would have served. Opt into blocking per rule when you have verified the constraint on the surface you dispatch through. See docs/batteries/validation/api-surface-scope.md.	src/batteries/validation/types.ts:169
type	"alternation"	Discriminator selecting the role-alternation evaluator.	src/batteries/validation/types.ts:144
