lifeloop-cli 0.1.0

//! Lifecycle integration profile abstraction tests (#26).
//!
//! These tests pin two things:
//!
//! 1. **Parity** — the back-compat free functions
//!    (`render_applied_assets`, `merge_claude_settings`,
//!    `merge_codex_hooks`, ...) produce byte-identical output to the
//!    explicit `*_with_profile(..., &CCD_COMPAT_PROFILE)` form. This
//!    is the safety net for the refactor: any in-tree caller that
//!    used the legacy API gets exactly the same bytes after #26 as
//!    before.
//!
//! 2. **Separation** — a non-CCD profile
//!    (`LIFELOOP_DIRECT_PROFILE`) renders distinct output that does
//!    NOT contain CCD-flavored command strings, AND the CCD-compat
//!    merge logic refuses to recognize a non-CCD profile's hook
//!    entries as managed (so the two profiles do not silently
//!    interfere when an installation is migrated between profiles).
