exfat.zig is a near-clone of fat.zig — the reuse the architecture promised, now real: same IpcBlock DMA-bounce wrapper, same acquire-volume-by-hello to the volume manager, same content-conditional boot rewrites (resolve /system/configuration to decide the system volume), all differences confined to the engine it wraps. That the harness's Server(engine.FileSystem) compiles is the proof the exFAT engine meets the same pub-fn contract as FAT — a comptime check, not a hope. The exfat package (build.zig + build.zig.zon) mirrors fat's: it ships in production_ship, its on-disk + engine host tests run through the root test aggregate (replacing the temporary standalone entry), and the root zon declares it. build + zig build test + bounds all green.
