Increment 2: WIREBIND user VMs (the ones that actually run FORTH work; console VMs are pure REPL proxies and never participate) register as Stage 3 switch-signal participants at attach, unregister at teardown. Slot table bumped 8 -> 16, matching messaging.4th's own VM-MAX -- a real, already-agreed ceiling, not an invented number. Added sk_vm_switch_signal_unregister() (compaction-based; Tripod VMs never needed removal, WIREBIND VMs cycle constantly and would otherwise exhaust the bounded table). Increment 3: implements the plan's own ratified option (A) for the async-detach UAF risk -- mark-and-defer via a new pending_reap flag on VMRegistryEntry, deliberately not a new VMState (capsule_vm_kill() already treats VM_STATE_DEAD as idempotent success, which would silently swallow a reap attempt; SWITCHED_OUT still accurately describes a tombstoned VM until the moment it's actually freed). unclean_detach() sets it when capsule_vm_kill() refuses a SWITCHED_OUT target; the Stage 3 checkpoint (vm_core.c) checks it before ever attempting to resume a pending switch target, and calls the new capsule_vm_force_reap() instead -- the one caller allowed to bypass capsule_vm_kill()'s own refusal, because it runs at the exact safe cooperative point the switcher itself controls. A new idle-tick sweep cleans up the WIREBIND live-table entry once the reap has actually happened. Verified clean on all 3 architectures (baseline regression -- no WIREBIND attach happens in a plain boot). The reap mechanism's own correctness under a genuinely parked context is verified separately, next, via a temporary deterministic probe.

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 thevm_*.cfiles, not part of the publicinclude/vm_api.hsurface.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; consumescompudynamics.cfor 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 inssm_jacquard.c.heartbeat_export.c— heartbeat metrics export (CSV export function itself not yet implemented — seedocs/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.
