Robert Allan JamesandClaude Sonnet 5 b42308762b FABRIC.md: 4.4g stays open (reorder not viable), add urgent item 4.6 (-O0 kernel build)
Attempted 4.4g's console_fb_init() reorder twice this session: once bare,
once with the fb_scroll_rows() volatile fix applied. Both stalled boot
indefinitely (12,000+ lines logged, still running after 3 minutes vs. a
normal few-second boot) instead of completing. Root cause traced past the
scroll fix to Makefile.starkernel building the kernel at -O0 -- no
optimization flag has ever been configured there, verified against the
file's full git history (17 commits, only ever one unrelated host-tool -O2
line). Both the kernel's own vendored hosted Makefile and the standalone
StarForth repo's Makefile default to -O2 (up to -O3/-flto on faster
targets); Makefile.starkernel was written fresh for the bare-metal target
and never got that ladder.

Documented as new item 4.6: enabling optimization is not a safe drop-in
change on its own. Found one confirmed, isolated correctness hazard first --
TimeTrustState.ticks (timer.h:90) is written directly in ISR context on all
three architectures (heartbeat.c:163) and read directly by mainline
(heartbeat.c:200-202, including a busy-wait in kernel_main.c:880) without
being volatile, unlike every other ISR-shared global checked
(g_spurious_count, g_plic_claim_count, g_pending_counter/g_pending_valid/
g_adaptive_period_ns are all correctly volatile already). Reverted the
console_fb_init() reorder itself (uncommitted, so a plain git restore) --
4.4g stays open pending 4.6.

Both the reorder attempts' logs (stalled, never reached ok>) and this
session's routine three-arch artifacts (capsules/BLOCK_MAP.md, disk/
artemis.img, DOE CSV) are committed as audit trail per CLAUDE.md.

logs/

QEMU acceptance-run history and Tripod smoke-test results.

  • <timestamp>/{amd64,aarch64,riscv64}/ — 255 timestamped three-arch QEMU acceptance run directories, one per invocation of the kernel QEMU acceptance workflow.
  • qemu-screenshot-*.png, qemu-screenshot-*.log, qemu-{amd64,aarch64,riscv64}-*.log, fbtest-console-*.png — loose timestamped QEMU serial captures and framebuffer screenshots from individual manual runs (not part of the timestamped-directory convention above).
  • hermes-tripod-smoke-results.md, hermes-channel-smoke-results.md — captured output from tools/hermes_tripod_smoke.sh and tools/hermes_channel_smoke.sh.
  • hermes-tripod-integration-design.md — design notes for the Tripod integration test.

Note: QEMU_BASELINE.log at the repo root (not in this directory) is the primary kernel regression baseline referenced by .claude/CLAUDE.md; the logs here are supplementary historical captures. See also logs2/ (a separate, flatter QEMU log archive) and experiments/bare_metal/runs/ (DoE-specific run output).
