GET /xrpc/com.atproto.sync.getRepoStatus

What com.atproto.sync.subscribeRepos’s #account says about one account, on request, with the rev a caller compares a relay’s copy against. The active and status pair is read through didbot_pds::HostedAccount::sync_status, the mapping the stream announces from, so this route and the next frame say the same thing. A relay holding an older frame is brought level by the announcement a boot makes of every position that changed — see didbot_pds::Provisioner::announce_accounts. An account that mapping announces nothing for — reserved, or still provisioning — is RepoNotFound here for the same reason it is silent there: a relay was never told it exists, and this route must not be the first to say so.
