capsule_birth.c hardcoded every new VM's initial Stadium quota grant to split from Hera specifically. Since a grant always halves whatever the donor currently has, Hera's own free list converges toward empty after a bounded number of grants — independent of whether the Stadium as a whole still had spare capacity, since VMs she'd granted to earlier typically still held nearly all of their own share untouched. Past that point every subsequent VM birth's Stadium grant would be silently refused (soft-failed, non-fatal by existing design), even with plenty of capacity sitting idle elsewhere. Fixed by adding an O(1)-maintained free_count to StadiumVMQuota (incremented in stadium_evict(), decremented at both of stadium_admit()'s free-list-pop sites, set/adjusted in stadium_grant_quota()'s own split — this also let grant_quota drop its old O(free-list length) counting walk in favor of an O(1) read) and stadium_best_donor(), an O(live VM count) scan over quota slots returning whichever in-use VM currently has the most free cells. capsule_birth.c's birth path now splits from that VM instead of unconditionally vm_uuid_hera(). Verified with another full rerun of the 3x9x3 std79 DoE campaign from scratch — same discipline as the prior Stadium fix (any defect repair reruns the whole DoE from the top) — one continuous boot per architecture, all 9 identities simultaneously live throughout. 81/81 trials correct, 0 mismatches, DOE-RUN header sequence md5-identical to every prior run. aarch64 ~280s total (vs ~290s for the O(ncells)-scan fix alone — confirms no regression). Both known Stadium defects are now closed together on one clean campaign rerun.

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).
