Robert Allan JamesandClaude Sonnet 5 dd043bbfeb Artemis Milestone 2e: PORTSC connect/disconnect detection, verified live
xhci_poll_events()'s Port Status Change branch now decodes the Port ID
from the event TRB (XHCI_PSC_EVT_PORT_ID, new in xhci.h), reads that
port's PORTSC.CCS via a new xhci_port_regs() helper, and logs connect vs.
disconnect. Acknowledges by writing back only PP (preserved) and CSC (the
bit being cleared) -- PED/PR/other _C bits written 0 so nothing is
accidentally disabled, reset, or silently cleared, matching the RW1C
discipline already used for ERDP.EHB in 2d.

Verified with the real target scenario via QMP hotplug on all three
architectures: boot with the xHCI controller present but no USB device
attached (confirmed zero port activity at ok>), then live
attach/detach/re-attach of a virtual USB thumb drive
(disk/usb-thumbdrive-test.img via usb-storage on xhci0.0). Full
connect->disconnect->connect cycle confirmed clean (no port wedge) on
amd64; single connect confirmed on aarch64 and riscv64.

Still open: correlating Command Completion Events back to their issuing
command, driving Enable Slot/Address Device from this connect path
(currently only a boot-time smoke test), and the callback surface into
Section U's higher-level code.

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.
