zerodds-security-runtime 1.0.0-rc.1

//! Conformance-Matrix fuer DDS-Security 1.2 §1.1 + §1.2 + §2.1.
//!
//! Verifiziert produktiv, dass:
//!
//! 1. Alle 5 SPI-Traits aus `zerodds-security` werden durch je einen
//!    Builtin-Plugin im Workspace erfuellt (`accepts_builtin_plugin`).
//! 2. Jedes SPI rejected ein "misimplemented" Plugin (Plugin mit
//!    leerer Class-Id oder Error-only-Verhalten) gemaess
//!    Spec-Vertrag (`rejects_misimplemented_plugin`).
//! 3. Die Conformance-Points-Tabelle aus §2.1 (Builtin Plugins,
//!    Plugin-Framework, Plugin-Language-APIs, Logging+Tagging-Profil)
//!    ist als Test-Tabelle exhaustiv abgedeckt.
//!
//! Spec OMG DDS-Security 1.2:
//! * §1.1 — DDS-Security-Compliance-Profile als Erweiterung von DDS.
//! * §1.2 — 5 SPIs: Authentication, AccessControl, Cryptographic,
//!   Logging, DataTagging.
//! * §2.1 — Conformance-Points: Builtin / Plugin-Framework /
//!   Plugin-Language-APIs / Logging+Tagging.
//!
//! zerodds-lint: allow no_dyn_in_safe
//! (Conformance-Matrix testet das Plugin-SPI gerade ueber `Box<dyn>`-
//! Erasure — das ist Sinn des Tests.)
