Finding 2 (putc/getc) fixed via shim.c backfill (previous commit). With both Finding 1 (-U_FORTIFY_SOURCE) and Finding 2 fixed, amd64 links clean at -O2 -- rigorously confirmed zero new warnings by diffing normalized warning text between -O0 and -O2 builds (empty diff, ~3040 pre-existing warnings in vendored code unchanged). New Finding 3, not fixed, now blocking: amd64 boot stalls for minutes inside calibrate_tsc_with_pmtimer() (timer.c:560-589) at -O2 -- a mainline busy-wait loop reading the ACPI PM Timer via genuinely-volatile inl() until 1000 real ticks elapse, bounded by a 5M-iteration timeout. A one-shot diagnostic probe (reverted after capture) caught exactly one checkpoint in 55 seconds of observation, then nothing -- not yet root-caused whether this is the 5M-iteration timeout itself taking several minutes to exhaust under -O2, or a genuine non-terminating condition. Makefile.starkernel reverted to -O0 again; nothing broken landed in history. Routine artifacts from this session's boot attempts included. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
