Tier-completion invariant audit
Returns the per-tier completion accounting for a batch: how many objects were submitted, how many ended up in the per-object success ledger (processed_objects), how many in the per-object failure ledger (failed_documents), how many were skipped, and how many are ‘lost’ (submitted but absent from both per-object ledgers).
Phase 1 of INGESTION_RELIABILITY_PLAN.md. has_lost_objects=true is a smoking gun for the row-failure-swallow class of bug — the tier was marked COMPLETED but rows silently went missing. Compare against tier_tasks[].audit (persisted at completion) to see the snapshot at the time the callback fired.
Authorizations
Mixpeek API key, sent as Authorization: Bearer mxp_sk_.... Create one in Studio under Settings → API Keys, or with an admin key via POST /v1/organizations/users/{user_email}/api-keys. A missing header returns 403; an invalid or revoked key returns 401.
Namespace id (ns_...), not the namespace name. This scopes the request rather than authenticating it, and it is required on every operation marked x-mixpeek-namespace-scoped.
Path Parameters
The unique identifier of the bucket.
The unique identifier of the batch.
