    The Hexclave REST API. All request headers are documented as canonical
    `X-Hexclave-*`; the equivalent `X-Stack-*` aliases are accepted on every
    endpoint for backwards compatibility. Response headers
    `X-Hexclave-actual-status`, `X-Hexclave-known-error`, and
    `X-Hexclave-request-id` are emitted alongside their legacy `X-Stack-*`
    equivalents.
