Robert Allan JamesandClaude Sonnet 5 5e9802845a Implement SCSI WRITE(10), closing the graph's highest-leverage blocker
Direct mirror of the existing READ(10) implementation (FABRIC-3.md §F.1),
data direction flipped: new XHCI_XFER_BOT_DATA_OUT/XHCI_NEXT_ACTION_BOT_DATA_OUT
states, xhci_bot_send_write10()/xhci_bot_write_block()/xhci_bot_write_data_out()
in xhci.c, new SCSI_CMD_WRITE10 opcode and BOT_CMD_WRITE10/BOT_TUR_CHAIN_WRITE10
enum values. usb_blk_write() in blkio_usb.c is real now, no longer the
BLKIO_ENOSUP stub. read_only flips to 0 in blkio_info() now that it's proven.

Verified live end-to-end on all three architectures with a genuine cold-reboot
round-trip (not just a same-session read): BLK-CONFIRM-FORMAT's BAM/reloc
writes and an explicit block content write both completed via clean WRITE10
cycles (CSW PASS), and the written byte read back correctly after a full
kernel rebuild + fresh boot -- amd64=65, aarch64=170, riscv64=201, each at
LBN 32734 on a disposable usbwrite-test.img attached via QEMU usb-storage.

Added Makefile.starkernel's QEMU_EXTRA (empty by default, no behavior change)
to attach the disposable test image for this validation; the drive must be
hotplugged via QMP after boot reaches ok>, not attached at QEMU launch --
attaching before xhci_bringup()'s controller reset means no fresh Port
Status Change event fires (see project_xhci_milestone_2d_polling memory).

Found and reported, not fixed, during testing: EMPTY-BUFFERS
(empty_all_buffers(), block_words.c) does not implement standard Forth-79
semantics -- it force-writes zero to every block on every attached device
instead of discarding cache assignments. This corrupted disk/artemis.img
during an earlier test run; restored from git, confirmed byte-identical.
Avoided in the final validation runs (detach/reattach used instead to force
a fresh read).

src/

Hosted StarForth VM implementation (compiled by the root Makefile). Bare-metal kernel sources live in src/starkernel/; FORTH word implementations in src/word_source/; the test harness in src/test_runner/; platform shims in src/platform/.

Entry point / interpreter core

  • main.c — CLI entry point, VM init, DoE mode dispatch.
  • vm.c — interpreter loop, stacks, dictionary state (the central runtime file).
  • vm_api.c — external VM API implementation.
  • vm_bootstrap.c — VM bootstrap initialization.
  • vm_debug.c — debugging utilities.
  • vm_time.c — time-related VM operations.
  • vm_internal.h — internal-only declarations shared across the vm_*.c files, not part of the public include/vm_api.h surface.
  • repl.c — REPL read-eval-print loop.
  • cli.c — CLI argument parsing.
  • io.c — I/O operations.
  • log.c — logging infrastructure.

Memory / dictionary / blocks

  • memory_management.c — dictionary allocator.
  • dictionary_management.c — dictionary allocation and search.
  • dictionary_heat_optimization.c — Loop #1 execution-heat tracking.
  • word_registry.c — word registration system.
  • block_subsystem.c — logical→physical block mapper.
  • blkio_file.c, blkio_ram.c, blkio_factory.c — block I/O backends (file-backed, RAM-backed) and the factory that selects between them.
  • stack_management.c — stack operations.

Physics-driven adaptive runtime (7 feedback loops)

  • physics_runtime.c — main physics coordinator.
  • physics_hotwords_cache.c — Loop #1 hot-words caching.
  • physics_metadata.c — per-word metadata tracking.
  • physics_pipelining_metrics.c — Loop #4 word-transition prediction.
  • physics_execution_hooks.c — execution instrumentation.
  • rolling_window_of_truth.c — Loop #2 circular execution-history buffer.
  • inference_engine.c — Loops #5/#6, statistical inference (window-width, decay-slope).
  • ssm_jacquard.c — L8 Jacquard steady-state mode selector; consumes compudynamics.c for tuning-word/config lookups.
  • compudynamics.c — generic compudynamics module (cd_tuning_word(), cd_tuning_vm()); the score/UCB/reward/weight constants for the L8 adaptive table live here, not in ssm_jacquard.c.
  • heartbeat_export.c — heartbeat metrics export (CSV export function itself not yet implemented — see docs/working/architecture/heartbeat_csv_export.md).

Math / measurement

  • math_portable.c — portable math functions.
  • profiler.c — performance profiling.
  • doe_metrics.c — Design of Experiments metrics (2^7 factorial).

Any .bak file alongside a .c file here (doe_metrics.c.bak, inference_engine.c.bak, vm.c.bak) is a pre-edit backup left by a past maintenance script (see scripts/remove_loop_conditionals.sh), not a build input.
