GET /api/audit/export?format=parquet returned 501. It now streams the same 24
columns as csv/jsonl (AuditExportRow, CsvHeader order) as one Parquet file,
one 10,000-row row group at a time. Each row group is encoded into a small
non-seekable staging buffer and copied to the response asynchronously, because
Kestrel rejects the synchronous writes the Parquet writer issues.
New management commands, with CLI parity:
- ListAuditArchives -> `audit archive list` (AuditArchiveListResult: enabled
flag + every manifest).
- VerifyAuditArchive(Name) -> `audit archive verify --name` (files, chain,
purge anchor); exit 0 verified, 3 not verified, 1 error, 2 unauthorized.
Both carry verify-chain's gate: OperationalAudit roles (Administrator, Viewer),
site-scoped non-Administrator refused because an archive spans every site.
VerifyAuditArchive uses the long-running Ask timeout. Error codes
ARCHIVE_NOT_CONFIGURED, INVALID_ARGUMENT, NOT_FOUND.
RequiredRoleMatrixTests freezes both gates; ManagementSurfaceParityTests now
probes `audit archive list|verify` alongside `audit verify-chain`.
