/**
 * `SAFETY_AXIS_VOCABULARY` — the PUBLISHED safety-axis vocabulary as a zero-logic, zero-runtime-dependency DATA
 * artifact (pure string / number / boolean literal constants).
 *
 * **design/99 center control-plane seam (2026-06-27).** The web-admin control plane's per-field
 * safety-classification table lives in `@sema-agent/registry-core` and, for every safety-critical config field, cites a
 * core axis VALUE (e.g. `effect: "write"`, `irreversibility: "always"`). That contract package **must not depend on
 * `@sema-agent/core` (the engine) at runtime** — so it dev-imports THIS const (test-only) and runs a conformance test
 * asserting every `coreAxis` string it ships is a legal value here, failing CI if core ever drops / renames one.
 *
 * Anti-drift discipline (mirrors {@link import("./safety-merge-corpus.js").SAFETY_MERGE_CONFORMANCE_CORPUS}, design/87):
 * the arrays are pinned to the engine's safety-axis source unions; `test/safety-axis-vocab.test.ts` regression-tests
 * them in lockstep with the engine version, and the `_AssertEqual` below fails `tsc` if `toolEffect` drifts from the
 * {@link ToolEffect} union (either direction). The const carries NO logic and imports NO runtime value — the emitted
 * JS is pure data, so a consumer can `JSON`-shaped-read it without pulling any engine code.
