Pure source rename across 11 std modules (~60 sites): cli/core/fmt/fs/log/
net/kqueue/process/socket/thread/time/trace. All fn-decl markers — bare
'#foreign;', '#foreign libc;'/'#foreign tlib;' (LIB ref), and
'#foreign libc "csym";' (LIB+rename) → the same 'extern …' tail (extern carries
the identical [LIB] ["csym"] axis). Plus 2 stale comment mentions (fmt/fs).
No class forms in std. These modules ARE host-corpus-exercised, so the empty
snapshot diff is direct validation. Suite green (647 corpus / 444 unit, 0
failed).
now_secs (CLOCK_REALTIME, epoch seconds) and mono_ms (CLOCK_MONOTONIC,
process-local milliseconds for deadlines). Clock ids are darwin's; the
per-OS selection mechanism is PLAN-HTTPZ C3. No error channel: with
module-constant clock ids and a stack timespec, clock_gettime is total.
std.sx namespace tail carries the time alias; examples/1629 pins epoch
plausibility, monotone advance, and the alias carry.
