Robert Allan JamesandClaude Sonnet 5 bbfd9103f4 Stage C: cut over BLK-ATTACH-EVENT alone -- FABRIC-3.6.md task 3.8
The reply leg (Artemis -> Hera ack) that used to flow through
common:messaging.4th's MSG-SEND/MSG-TICK now goes through
kernel-Hermes's sk_hermes_send_one()/sk_hermes_drain_checkpoint()
instead -- FORTH Hermes never sees a BLK-ATTACH-EVENT message again
(SXXXIV.2's partition rule). The request leg was never real FORTH
messaging traffic to begin with (a direct VM-EXEC, no type tag,
forced by Hera's own inability to load common:messaging.4th), so it
is untouched.

New KH-BLK-ATTACH-SEND (repl.c) wraps sk_hermes_send_one(), reached
from capsules/artemis/init.4th's HERA-BLK-ATTACH-REQ. Delivery reuses
task 3.4's already-wired sk_hermes_drain_checkpoint(); BLK-ATTACH-ACK
itself is unchanged, just reached by a different layer.
SK_HERMES_MSG_TYPE_BLK_ATTACH deliberately reuses BLK-ATTACH-EVENT's
own value (9) to document this as a cutover of the same message, not
a new one.

Two real bugs found on the way, both recorded in FABRIC-3.6.md's
findings log:
- A popped FORTH CREATE-buffer address was raw-cast to a host pointer
  instead of going through vm_ptr() -- silently read all-zero memory,
  no crash, no error, just a message that arrived and did nothing.
  Fixed; the rule and its exception (repl.c's own dev-addr is
  legitimately a raw pointer, formatted that way by its own pushing
  code) are written up for the next FORTH-facing C word.
- A separate, genuine hang on the very first live exercise of this
  path, never reproduced across ten subsequent boots. Reported, not
  chased -- not blocking, per the task's own check being otherwise
  fully satisfied.

Also found live: log_message() is invisible in this build's actual
serial-log capture at every level -- settled on a single
console_println in the real drain target instead, one line per real
USB attach, not a hot-path.

Final acceptance (logs/20260922-105501, -105758, -110304, disk images
reset before each): dict_hash identical across all three
architectures for every VM, zero UNKNOWN WORD, mkcapsule --lint
clean, real ledger+stadium_conserved(Artemis)=true evidence on every
boot.

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.
