# contracts.resolve_usage_review

Record the business's decision and reason for selected contract usage attention items, amendment price checks or unmatched vendor lines. Changes no bill or posting.

## What it does

Read the contract through subjects get, then select attention.usageReview.items by reason, activityKey, periodKey and sourceFactId. Or read usage_estimates and select pending unmatchedLines by reconciliationId and lineKey. For an amendment price check, select priceDifferences by activityKey, basis (amendment_credit or amendment_charge), latest, billed, bills and the full standing list from attention.priceDiffers. A change to any selected snapshot value requires reading attention again.

This acknowledges every unresolved amount in that selected check, including older standing bills, without changing money or matching tolerance. Select 1 to 50 items, checks and lines in total. Record the business's decision and reason; only selected items and price checks leave attention and selected lines leave the pending unmatched report. Reuse the same selections in a later command to supersede an earlier decision, retaining every decision and caller in event history with predecessor CIDs.

An unmatched-line selection may give accountedBy: { cid } referencing the event that recorded its accounting; a replacement supplies its own optional reference. Record or correct bills separately with contracts.record or contracts.reconcile_usage.

## Before you send it

An authorized OAuth connection may call it, including a headless client. Effective membership, application grant and token permissions still apply. Describe `contracts.resolve_usage_review` through `GET /v1/catalog/commands/{name}` before acting.

This command does not accept `source_document_id` in its envelope. Any input evidence requirements remain as documented below.

## Inputs

Put these fields inside the envelope's `input` object. The outer envelope names the command, a stable `idempotency_key` and `effective_at`; [request and recovery rules](/docs/api/) explain those separately. Use exact minor-unit integer strings for monetary fields. Take existing IDs from prior reads or command results; choose a new identity only where the command asks for one.

Required means required within its containing object; an optional parent can be omitted.

## After acceptance

When the command emits events, its documented effects and receipt are recorded in the command transaction. The response returns `commandId`, `replayed`, the command-specific `result` below and emitted `events` with their IDs and CIDs. A command is not automatically a cash movement or revenue recognition: use the behavior above to determine what this command records.

Inspect `result` and the affected records or reports before continuing. Save returned identifiers for later calls. Fetch `GET /v1/commands/{id}` with `commandId` to recover the accepted receipt; retry the same intent with the same idempotency key if the response was lost. Some commands can succeed with `events: []` and return a transient result and `commandId` without persisting a receipt. A lookup of that ID can return null; retain the returned result and verify the affected record. Retrying can re-evaluate the current state rather than replay a stored result. A domain `no_change` is a separate success outcome with no persisted receipt.

### Result fields

Required means required within its containing object; an optional parent can be omitted.

| Field | Type | Required | Meaning and accepted values |
|---|---|---|---|
| `resolved` | integer | Yes |  Minimum: `1`. Maximum: `50`. |
