library/runtime/log.zig wires std.log to the tagged ring: the root shim installs std_options for every binary (programs may override), logFn formats one line per record and emits it with its level via debug_write — the payload no longer carries the process's name; the kernel stamps identity structurally and the serial renderer prints the '<binary path>: ' prefix, so the transcript keeps its shape. Migrate every writeLine/logLine/log helper family (init, vfs, fat, device-manager, acpi, pci-bus, ps2-bus x3, usb-hid x2, usb-storage, usb-xhci-bus, virtio-gpu — 104 call sites) to std.log.info, dropping the hand-written prefixes. A leveled record is a complete line by contract (raw emissions may still build lines from pieces). Test fixtures and the display/input services keep raw writes for now — their ring records are attributed by the kernel regardless. Harness regexes follow the renamed prefixes (usb-hid-keyboard, discovery) and path-named restart lines.

//! The root module every user binary is compiled through (build.zig,

//! shim contributes the declarations Zig resolves from the compilation root —

//! `main` (dispatched by runtime.start) and the panic handler — and pulls in the
|

//! `_start` entry shim. A program therefore only defines `pub fn main`; nothing
