gcry is a Crystal-native, shard-delivered conservative mark–sweep garbage collector that replaces Boehm when an application is built with -Dgc_none. The documented runtime workflow routes Crystal allocation through gcry’s GC interface, tracks heap objects and roots, marks reachable objects during stop-the-world collection, then sweeps and releases unused memory. The README also documents platform support, optional precise-layout research mode, and built-in metrics. The supplied source excerpts mainly identify override, raw-output, scan, and stop-the-world modules; internal call wiring beyond the documented workflow is therefore kept intentionally broad.
