// Cross-Fediverse scenario — runs whenever Mastodon AND Friendica are
// deployed alongside fediwall. The test is fully data-driven against
// each wall's `wall-config.json` `servers` list:
//
//   - biber posts a unique status to BOTH Mastodon and Friendica via
//     the same SSO/ldapauth UI flow a human would use (LDAP is the
//     single source of truth for biber's credentials; the local
//     accounts on Mastodon/Friendica come into existence lazily on
//     first SSO login, exactly as in production — no API auth, no
//     password duplication, no manual user provisioning).
//
//   - For every deployed wall, the test reads `wall-config.json`
//     and asserts: a sibling's post is visible iff that sibling's
//     domain is listed in `servers`; otherwise it MUST NOT appear.
//
// This single test covers both variants automatically:
//   variant 0 — one wall polling all active siblings (both posts visible)
//   variant 1 — two walls; one polls both siblings, the other only
//               Mastodon (friendica post must be absent there).
