StarForth/src

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.
