Robert Allan JamesandClaude Sonnet 5 28c1b12c7f Wire homeblocks_sig_check() into USB attach: the warn half (Phase 8)
Wired into sk_repl_idle()'s USB hotplug attach handler, right between
blkio_usb_open_msc() succeeding and blk_subsys_attach_device() -- logs
a distinct message per outcome (recognized / blank-or-foreign /
bad-version / bad-crc / read-error).

The "refuse" half is deliberately not implemented -- there is nothing
real to gate yet. blkio_usb.c has no SCSI WRITE(10) support at all, so
there is no write path today to refuse; attach currently only enables
read-only access, which is also the general-purpose USB block I/O
path this repo already relies on for unrelated testing, not
exclusively a home-blocks identity workflow. Refusing attach on blank
media would break that legitimate use without protecting anything
real -- same "don't build ahead of a real caller" reasoning EXPIRE's
deferral used. Refuse belongs on the write path once WRITE(10) exists.

sig_start_fblock is hardcoded to 0 at the call site -- correct for
today's unpartitioned raw test/real media (no GPT parser exists yet),
flagged in the comment as the one place that changes once a real
GPT-partition-relative lookup exists, isolated from
homeblocks_sig.c's own location-agnostic check logic.

Verified live: hot-attached disk/usb-thumbdrive-test.img (blank media)
through a running amd64 instance's QMP socket (blockdev-add +
device_add usb-storage) -- captured exactly 4 real TUR+READ10 BOT
cycles (matching the header's 4 forth-block span) followed by the
correct "not recognized" warning, then normal attach completing
successfully afterward (no regression). Conservation intact, no
panic. Clean zero-warning compile and clean boot on all three
architectures.

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.
