 * Invariant: the repository root must not contain ad-hoc AI instruction files
 * (such as AGENTS.md) that would become an untracked source of truth running
 * in parallel with the canonical CONTEXT.md and docs/adr/ records.
 *
 * Context: historically bin/install.js (the since-retired local install
 * path, issue #786) wrote an AGENTS.md to process.cwd() when run inside a repo
 * checkout. If such a file is ever committed, editors and AI tools that auto-load
 * repo-root instruction files will silently pick up an installer-generated
 * stub rather than the authoritative documentation. This test ensures that
 * artefact never lands in source control.
