/**
 * Mirror conformance guard (P1.2).
 *
 * Compile-time assertions binding the hand-mirrored v2 plugin context in
 * `./types.ts` to the official `@opencode/plugin` types (pinned to the
 * audited version in devDependencies). Enforcement point is `bun run
 * typecheck`: this file must NOT carry a test suffix, because tsconfig
 * excludes test-suffixed files (`*.test.ts`) from tsc — a test-suffixed
 * guard silently checks nothing.
 *
 * This file is deliberately NOT imported by any entry point, so it never
 * reaches the runtime bundles, and it uses `import type` only, so it
 * never loads `@opencode/plugin` at runtime.
 *
 * Layers:
 *  1. Pin the official session hook surface exactly. Bumping the
 *     devDependency past an OpenCode-core hook change fails typecheck
 *     here first.
 *  2. The hook names the mirror registers exist officially, and the
 *     official-name subset the mirror's hook signature accepts equals
 *     the declared list — stale guard lists and mirror overloads that
 *     appear/disappear both fail.
 *  3. Official payload fields the bridges rely on exist with the shapes
 *     the bridges assume.
 *
 * Known residual: a NEW mirror hook overload using a non-official name
 * is invisible to layer 2's derivation (which filters official names
 * only). Add such names to `MirrorSessionHookNames` explicitly; layer
 * 2a then fails until the name is official — which is the intended
 * alarm. Deleting this file goes unnoticed by `bun test`; it is
 * referenced from docs/opencode-v2-compatibility.md instead.
