Four bugs found live verifying the 8 identity thumbdrives (FABRIC-3.md §IX)
All found by actually running the identity workflow §VII/§VIII made
possible, not by code review:

1. Zuse/WIREBIND cross-contamination on detach: capsule_zuse_boot_logout()
   and capsule_wirebind_unclean_detach() both had no device parameter, so
   an unrelated device detaching (while the real owner's own stayed
   attached) incorrectly tore down the wrong session. Both now compare
   the departing device against their own tracked one, mirroring
   capsule_wirebind.c's pre-existing g_wirebind_attached_dev precedent.

2. Dictionary-entry memory leak: vm_create_word()'s sf_malloc()'d
   DictEntry (plus a second per-entry allocation for transition_metrics)
   was never freed by vm_cleanup(), in both the hosted and kernel
   implementations. Caused a real kernel PANIC after 8-9 repeated VM
   birth/kill cycles in one boot. Fixed by walking vm->latest in both.

3. sf_malloc/sf_free (alloc_kernel.c) was a 4MB bump arena with a
   deliberate no-op free, sized on "VM born once, never killed" -- fix #2
   alone didn't stop the panic because free() itself discarded the
   pointer regardless. Given a real free list (first-fit reuse).

4. Headless-console gate didn't re-engage after a mid-boot logout: the
   original fix (sk_console_mark_login(), one-way sticky) only gated the
   first login of the boot. Replaced with a live check
   (sk_console_identity_present()) re-evaluated continuously, including
   inside sk_console_readline()'s own blocking idle loop -- the console
   is normally sitting blocked there when a hot-unplug logout happens, so
   checking only at the top of the REPL loop wasn't enough.

Also: MINT now verifies its own write (verify_mint(), capsule_mint.c) by
reading back through the same check a real attach performs, rather than
trusting blkio_write()'s BLK_OK alone -- logged via log_message(), not
console_println(), per direct instruction.

Verified live, amd64: the full 8-identity repeated attach/detach cycle
that previously panicked at the same point every time now completes
clean, and a full serial-log sweep found zero bare unauthenticated
prompts anywhere in the run. Three-arch clean-qemu acceptance passed.

Still open, not fixed here: a 3+-simultaneous-device USB enumeration
failure found in a separate live test, not yet root-caused.

Public headers for the hosted StarForth VM (src/). Kernel-only headers live under include/starkernel/.

Core VM

  • vm.h — the VM struct and all core types (DictEntry, DictPhysics, stacks, dictionary state); the central header most other files include.
  • vm_api.h — external VM API surface.
  • vm_host.h, vm_debug.h, startup.h, version.h — host integration, debug utilities, startup sequencing, version string.
  • cli.h, repl.h, io.h, log.h — CLI parsing, REPL loop, I/O, logging.
  • word_registry.h — word registration system shared by every src/word_source/*.c file.
  • compudynamics.h — the generic compudynamics module: tuning-word/config lookups (cd_tuning_word(), cd_tuning_vm()) consumed by ssm_jacquard.c.

Memory / blocks

  • memory_management.h, dictionary_management.h — dictionary allocator and search.
  • block_subsystem.h, blkcfg.h, blkio.h, blkio_factory.h — logical→ physical block mapper and pluggable block I/O backends (file/RAM).
  • platform_alloc.h, platform_lock.h, platform_time.h — platform abstraction shims (hosted vs. kernel allocation/locking/timing).

Physics-driven adaptive runtime (7 feedback loops)

  • physics_runtime.h — main physics coordinator.
  • physics_hotwords_cache.h — Loop #1, execution-heat hot-words cache.
  • physics_metadata.h — per-word DictPhysics metadata tracking.
  • physics_pipelining_metrics.h — Loop #4, word-transition prediction.
  • physics_execution_hooks.h — execution instrumentation hook points.
  • rolling_window_of_truth.h, rolling_window_knobs.h — Loop #2 circular execution-history buffer and its tuning knobs.
  • inference_engine.h — Loops #5/#6, window-width and decay-slope statistical inference.
  • dictionary_heat_optimization.h — Loop #1 heat counters.
  • ssm_jacquard.h — L8 Jacquard steady-state mode selector.
  • doe_metrics.h — Design of Experiments (2^7 factorial) metrics.
  • profiler.h — performance profiling hooks.

Arithmetic / codegen

  • q48_16.h — Q48.16 deterministic fixed-point arithmetic (used instead of IEEE-754 float specifically to keep cross-architecture behavior bit-identical).
  • math_portable.h — portable math helpers.
  • arch_detect.h, starforth_config.h — architecture detection and the build-flag fallback-default layer (used when a .c file is compiled by hand without make).
  • vm_asm_opt.h, vm_asm_opt_arm64.h, vm_asm_opt_riscv64.h, vm_inner_interp_asm.h, vm_inner_interp_arm64.h, vm_inner_interp_riscv64.h — per-architecture assembler-optimized inner interpreter (USE_ASM_OPT=1).

See include/starkernel/README.md for the bare-metal kernel headers.
