Interface: CheckpointState

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

The canonical-history snapshot at a turn boundary.

Properties

Property	Type	Description	Defined in
`compaction`	`number`[]	Compaction points; producers arrive with M4-T03.	`packages/core/dist/index.d.ts`
`messages`	`Msg`[]	Canonical history up to and including the boundary.	`packages/core/dist/index.d.ts`
`pending?`	`PendingToolTurn`	Present while an ask suspension holds the turn open (M3-T03).	`packages/core/dist/index.d.ts`
`providerCalls?`	`ProviderCallRecord`[]	The per-dispatch reconciliation ledger so far (P1.3), carried at every boundary so a kill-and-resume keeps pre-kill wire calls attributable. Absent before the first call and on checkpoints written before the ledger shipped: those restore none, and the invoice fold surfaces the restored usage as an unattributed remainder instead of losing it.	`packages/core/dist/index.d.ts`
`schemaAttempts`	`number`	-	`packages/core/dist/index.d.ts`
`toolCallsUsed`	`number`	-	`packages/core/dist/index.d.ts`
`turns`	`number`	Model turns already paid.	`packages/core/dist/index.d.ts`
`usage`	`Usage`	Usage accumulated so far (not yet journaled: terminals carry totals).	`packages/core/dist/index.d.ts`
`usageByModel?`	`UsageSlice`[]	The same usage split by serving model, so a dangling redispatch restores the per-model breakdown instead of collapsing every paid turn onto the loop model. Absent on checkpoints written before the split shipped: those restore the aggregate against the loop model, exactly as they did then.	`packages/core/dist/index.d.ts`
`v`	`1`	-	`packages/core/dist/index.d.ts`
