Completes the highest-priority item from
docs/working/archive/session-logs/2026-07-24-punch-list.md (item #1),
intentionally deferred out of commit 4485c38 as a separate, more careful
change.
vm_pop_asm/vm_rpop_asm's inline asm referenced the dsp/rsp memory operand
twice (read near the top, write-back near the bottom) while also writing
a plain register output operand (%[val]) in between. Nothing pinned the
address register computed for the memory operand across that gap, so
clang's allocator could reuse it for %[val], corrupting the write-back.
GCC happened to pick different registers and never hit it — this repo's
kernel build uses GCC and USE_ASM_OPT is never defined there, so the bug
was latent, not live, prior to this fix.
Fixed by reordering: write dsp/rsp back before loading the popped value,
so the memory operand's final use has already happened by the time the
output register is live. Same fix as the old pre-split monorepo's master
commit 4db9946a, re-derived here since that commit lives in a different
repository post-split.
Verified empirically, not just theoretically: rebuilding the riscv64
hosted binary with the documented clang -O3 -DUSE_ASM_OPT=1 acceptance
recipe went from 955 passed / 10 failed (all CASE.* control-flow tests —
exactly what stack-pop corruption would hit) to 965 passed / 0 failed,
"ALL IMPLEMENTED TESTS PASSED!", with nothing else changed. All three
Makefile.starkernel kernel builds still compile clean; the change is
inert there since USE_ASM_OPT is never defined for the kernel build.

include/
Public headers for the hosted StarForth VM (src/). Kernel-only headers
live under include/starkernel/.
Core VM
vm.h— theVMstruct 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 everysrc/word_source/*.cfile.compudynamics.h— the generic compudynamics module: tuning-word/config lookups (cd_tuning_word(),cd_tuning_vm()) consumed byssm_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-wordDictPhysicsmetadata 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.cfile is compiled by hand withoutmake).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).
