Per .claude/CLAUDE.md's non-negotiable acceptance criteria, ran
`make -f Makefile.starkernel ARCH=<amd64|aarch64|riscv64> clean qemu`
sequentially (one instance at a time, TCG) against the preceding commit.
All three booted cleanly to `(zuse) ok>` with identical dictionary hashes,
no regression from the new idle-tick overflow check.
Also includes the amd64 run (20260905-161517) that carried the temporary
TEST-OWNER-CLAIM diagnostic via SK_CMD, confirming blk_owner_has_claim()
live before the diagnostic word itself was reverted: PASS, no FAIL lines.
