Interface: PreservationRule

Requires historical primitive content to remain present and/or stable.

Properties

Property	Type	Description	Defined in
`id`	`string`	Stable identifier used in violations and snapshots.	src/batteries/validation/types.ts:124
`invariant`	\| `"count-non-decreasing"` \| `"payload-field-stable"` \| `"pruned-after-latest-turn"`	Continuity invariant: `count-non-decreasing` never permits historical loss, `payload-field-stable` preserves a selected field, and `pruned-after-latest-turn` permits absence only before the latest non-tool-call user Message; content after that boundary must remain present AND unchanged, mirroring `payload-field-stable` for the retained recent range. The latter means never drop recent or alter it, may drop old, and is distinct from full-history preservation.	src/batteries/validation/types.ts:139
`kind`	`OrderingPrimitiveKind`	Historical primitive kind whose continuity is required.	src/batteries/validation/types.ts:126
`payloadField?`	`string`	Dot-path into the primitive payload when `invariant` is `payload-field-stable`.	src/batteries/validation/types.ts:141
`resetOnModelSwitch?`	`boolean`	Reset the comparison baseline when the producing model changes.	src/batteries/validation/types.ts:143
`type`	`"preservation"`	Discriminator selecting the stateful preservation evaluator.	src/batteries/validation/types.ts:122
