The macOS malloc_zone_pressure_relief call (returns freed allocator pages after raw decodes) lived in identical copies inside the desktop app and the CLI. It now lives in lightcraft-sysmem, an isolated L0 helper crate and the workspace's only crate allowed unsafe: one #[allow(unsafe_code)] module, a SAFETY comment, a safe API that returns bytes released (0 off macOS), and tests (repeat calls, release after large frees, concurrent calls). Both apps' alloc_release.rs now just install the safe hook, and their crate roots gain #![forbid(unsafe_code)], so every production crate except sysmem forbids it. AGENTS.md/CLAUDE.md name the exception, per craftrules standards/never-crash.md. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
