Hare-shaped lib/log v1: logger vtable carrying one println slot, stdlogger forwarding to a *io.stream, plus *logger globals (silent / default / global), setlogger, lprintln / println, lfatal / fatal. Default sink is stderr through a private rt_syscall write callback; graduates with #17 (cgen mod-mangle for fn labels), at which point the rt_syscall stub disappears the same way fmt's will. Module-scope struct/pointer-literal init isn't constexpr in cstage emit_lets, so silent/default/global are wired lazily by ensureinit on the first exported-fn entry (lib/temp rnginit pattern). Callers that read the globals directly must call some lib/log fn first. Skipped this round: printfln / lprintfln / fatalf / lfatalf and the matching printfln vtable slot — they need a fmt {n}-placeholder parser that isn't shipped yet. fatal / lfatal's exit(255) arm has no test fixture (needs fork+wait for WEXITSTATUS); left as TODO. 971_log_run wraps the @test fixture under `ww run`, mirroring 970_fmt_run. make test: 54/54; bootstrap fixed-point (990-997) holds.

* 971_log_run — execute the lib/log @test fixture under the C-side
|
|
* `ww run` driver and assert exit 0.
|
|
*
|
|
* log sits at the same tier as fmt (both consume io.stream sinks);
|
|
* slotting at 971, adjacent to 970_fmt_run, keeps both stdlib-runtime
|
|
* tests ahead of the 980-989 sub-band. logtest.ww carries its own
|
|
* `export fn main()` that drives the @test fns and signals which
|
|
* case failed via the exit code, so this file is a thin wrapper —
|
|
* no @test scanning, no synthetic main generation.
