Boolean analogue of vm_physics_conserved(), for the Stadium per-VM
quota invariant rather than fleet-wide execution heat
(FABRIC-3.5.md SXXXIX.4). int stadium_conserved(VMUuid vm_id), in
src/starkernel/vm/stadium.c alongside stadium_resident_sum()/
stadium_reservoir_peek() that it's built from, declared in
include/starkernel/vm/stadium.h.
Implements the two-term form -- resident_sum(vm_id) +
reservoir_peek(vm_id) == Q48_ONE -- not the three-term form SXL.4
rules for the eventual system. That ruling's `consumed` term is a
Phase 2 kernel-Hermes ledger deliverable that doesn't exist yet:
nothing draws on any VM's Stadium quota today (task 2.2 is literally
where that wiring gets built), so consumed is honestly zero right now.
Folding it in as a placeholder would be inventing Phase 2 state ahead
of it existing -- the doc comment says so explicitly, so whoever
builds Phase 2's ledger extends this function rather than working
around it.
Wired into the existing per-VM boot diagnostic
(stadium_words_print_boot_diagnostics(), kernel_main.c:810, Hera
only -- the sole existing call site) rather than adding a new one,
printing CONSERVED/DRIFTED the same shape vm_physics_status() already
uses.
Three-arch boot clean: amd64/aarch64/riscv64 all reach [zuse@Hera] ok>,
zero UNKNOWN WORD, all print "Stadium conservation: CONSERVED" with
identical resident_sum=47641 reservoir=17895 sum=65536=Q48_ONE. No
compiler warnings on either edited file (forced recompile checked).
Authorized by Captain Bob ("Yes.").

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).
