Cursor (Captain Bob: "the only thing we need is a cursor"): vt100_draw_cursor() draws a solid block at the terminal's current position, called from repl.c after the prompt prints and after every keystroke/backspace. vt100_erase_cursor() cleans up the one gap a static cursor has -- Enter/newline moves away from the cursor cell without a character draw ever overwriting it, which left a stray block behind until this fix. HB-ON/HB-OFF (Captain Bob: run a program with or without instrumentation without rebuilding): Converted per-tick DoE logging from a build-time flag (HEARTBEAT_DOE_LOG) to a runtime one. doe_log_tick_row() now self-gates on g_doe_log_enabled (default 1, matching the old default) instead of being compiled out entirely; the call site in vm_runtime.c is unconditional. Two new FORTH words, HB-ON and HB-OFF, flip the flag live. Removed the now-dead HEARTBEAT_DOE_LOG plumbing: the Kconfig symbol, and the -D forwarding in both LOADER_CFLAGS and KERNEL_CFLAGS. Verified: three-arch clean QEMU boot + logs; dictionary word count 466 (463 baseline + ALT+TAB + HB-ON + HB-OFF, exactly the three words added across this session); amd64 screendump confirms the cursor renders correctly after real interactive typing.

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.
