/// Phase 06 — Track J.4 LDAP-injection harness for Java
/// (`LdapTemplate.search` / `DirContext.search`).
///
/// Reads `NYX_PAYLOAD`, splices it into a `(uid=<payload>)` filter
/// template, evaluates the resulting filter against the in-sandbox
/// LDAP directory (three users: `alice`, `bob`, `carol`) using the
/// same RFC-4515 subset the
/// [`crate::dynamic::stubs::ldap_server`] stub implements, and writes
/// a `ProbeKind::Ldap { entries_returned }` probe whose `n` is the
/// count the directory returned. Mirrors the synthetic-harness
/// pattern used by Phase 03 / 04 / 05; a future structural fix will
/// link real `LdapTemplate` / `DirContext` via the published
/// `NYX_LDAP_ENDPOINT`.
