/**
 * PRI-480 — Phase 1 Core ABI (rule-context-v2.ts)
 *
 * Pure logic: types + canonicalize + validators + behavior-facts computation.
 * Zero I/O — this module MUST NOT import node:fs / node:path / better-sqlite3 /
 * any network module. The runtime-v2 architecture-regression test enforces the
 * file boundary.
 *
 * Err-prevention:
 *   - ERR-001 (validate-as-unknown): every public validator takes `unknown` and
 *     validates structurally. No `as` bypass on parsed input.
 *   - ERR-076 (prototype-pollution / host-realm independence): structural checks
 *     use Object.keys + a PROTO_KEYS set. We never touch the host realm's
 *     prototype chain (no `instanceof`, no `in`).
 *   - rc-2: no `as` casts on parsed input.
 *   - rc-5: Object.hasOwn / Object.keys over the `in` operator.
 *
 * Spec: docs/superpowers/specs/2026-06-27-rulecode-context-vision-design.md §4.
