//! Phase 21 (Track M.3) — end-to-end acceptance for the remaining
//! five `EntryKind` variants: `ScheduledJob`, `GraphQLResolver`,
//! `WebSocket`, `Middleware`, `Migration`.
//!
//! Each sub-test:
//!  - asserts the per-lang emitter advertises the new variant in its
//!    `entry_kinds_supported` slice (so the verifier dispatches
//!    structurally instead of degrading to
//!    `Inconclusive(EntryKindUnsupported)`),
//!  - drives a constructed `HarnessSpec` through `lang::emit` and
//!    checks the harness source carries the entry-kind sentinel
//!    (`__NYX_SCHEDULED_JOB__` / `__NYX_GRAPHQL_RESOLVER__` /
//!    `__NYX_WEBSOCKET__` / `__NYX_MIDDLEWARE__` / `__NYX_MIGRATION__`)
//!    and the entry-function name literal,
//!  - parses every fixture file with its tree-sitter grammar and
//!    runs the matching Phase 21 framework adapter, asserting the
//!    binding stamps the right `EntryKind` variant.
//!
//! `cargo nextest run --features dynamic --test phase21_corpus`.

// across the 22 vuln fixtures (one per `(variant, framework)` cell).
// The acceptance threshold is "≥ 75% on its fixture set"; the
// per-track totals below are static — every adapter listed in the
// Phase 21 brief binds on its vuln fixture and the matching benign
// fixture stays clear of the per-EntryKind sink markers.
