      description: 'Requires finance:einvoices:read and a tenant-owned, retained completed

        validation or generation result with all findings present. Truncated

        findings return 422 report_incomplete. Signing is separately configured;

        unavailable signing or rendering returns 503 report_unavailable.

        Send operation_id and optional include_pdf in a JSON body of at most 1024

        bytes. Query parameters, compression and Idempotency-Key are rejected.

        The ZIP includes a canonical manifest, domain-separated Ed25519 signature,

        exact saved result, complete findings and a readable HTML report. Generated

        XML is included when retained; include_pdf also binds a fresh readable PDF

        and its template version. Validation-only results cannot include a PDF.

        Optional RFC 3161 timestamps are signed as required when configured.

        There is no new validation, usage charge or hosted report retention.

        Issuance time/signatures may change on repeated downloads; original facts

        stay pinned. Expiry/deletion is checked again before releasing the bundle.

        Issuance has a 45-second deadline, two slots per API process and a 48 MiB

        compressed/expanded bundle limit. A signature does not certify compliance.'

        Ironfang Finance verifies the canonical manifest, domain-separated signature

        against operator-controlled public keys, every bundled artifact hash and

        the optional timestamp against configured TSA trust roots. It performs

        no network access, no PHIVE validation and no upload retention. For a

        completely local check use `ironfang finance verify` with independent trust keys.

        HTTP 200 contains verified true or false. Verified means report integrity,

        not a valid invoice; inspect invoice_outcome separately. Unknown or revoked

        keys, tampering, missing timestamp trust and unsupported schemas fail.

        Requests are bounded to 48 MiB compressed and expanded, nine allowed ZIP

        members, two concurrent checks per API process and a 15-second deadline.

        No query, compression or Idempotency-Key is accepted. Per-address anonymous
