bvisor 0.9.0

Sync-first boundary supervisor: platform-agnostic boundary contract (types + fail-closed planner) with real Linux (landlock/seccomp/cgroups) and Wasm (wasmi/WASI) confinement backends. ZERO OS code, ZERO BatPak writes in the Backend trait.

//! bvisor-core — platform-agnostic boundary contract.
//!
//! **ZERO OS code, ZERO BatPak writes in the [`Backend`] trait.**
//!
//! bvisor is a sync-first boundary supervisor. The Boundary Adapter Layer (BAL,
//! prose only) lowers admitted [`Capability`]s + [`HostControl`]s from a
//! [`BoundaryPlan`] into honest platform [`Backend`]s; the [`BoundaryRunner`]
//! SEALS a [`BoundaryReport`] and the host PERSISTS it into BatPak.
//!
//! The loop (sealing ownership made precise):
//! ```text
//! BoundarySpec     asks      (Capabilities + HostControls + workload)
//! BoundaryPlanner  admits    → BoundaryPlan   (inert IR, bound to backend + machine profile; fail-closed)
//! Backend          OBSERVES  → BoundaryReportBody (unsealed facts; no hashing, no BatPak)
//! BoundaryRunner   SEALS     → BoundaryReport (canonicalize + body_hash)  [SEALED ≠ persisted]
//! Host             PERSISTS  → appends 0xE event into BatPak              [now durable; replay reconstructs]
//! ```
//!
//! C0 scope: the pure contract + a fail-closed planner + the honest
//! [`InertBackend`]. No real OS backends, no `SimBackend`, no host wiring yet.
