Robert Allan JamesandClaude Sonnet 5 6e9c1d3bc2 Phase 8 C (4/n): metadata fence allocator integration + zone I/O
Corrected meta_fence_blocks units from "Forth 1 KiB blocks" to 4 KiB
devblocks (matching bam_devblocks/reloc_devblocks) before anything
depended on the original meaning -- a clean fix, not a migration. This
let the fence fold directly into compute_totals_from_B()'s existing
payload4k formula (total_devblocks - 1 - B - R - F) instead of a
separate user_blocks subtraction: total_blocks/user_blocks/free_blocks
all shrink correctly for free, in both the fresh-format and reload
paths, from one formula change.

New blk_meta_zone_read()/blk_meta_zone_write() -- raw, unpacked 4 KiB
devblock I/O, same shape as the header/BAM/reloc-table regions,
addressed by devblock_from_top counting down from the device's last
physical devblock. Refuses rather than clamps if the index exceeds the
on-disk meta_fence_blocks. C-only, no FORTH word wraps either -- same
discipline as vm_zuse_cert_install(), which will be this zone's first
real tenant.

Verified independently at every step, never trusting the kernel's own
report: capacity math cross-checked against a from-scratch Python
recomputation of the same formula (exact match); accessor correctness
via a temporary probe (written/run/captured/reverted) that wrote a
known pattern and read it back, then independently confirmed via a raw
read of the disk image at the exact expected physical byte offset.
Full 3-arch acceptance boot against the real, untouched disk/artemis.img,
probe code fully reverted -- clean, conservation intact.

Still open: wiring vm_zuse_cert_install() to actually persist through
these accessors, and the MINT word itself. Documented in FABRIC-3.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).
