FABRIC-3.md §XXXV.12: closes two real gaps found by walking the disk-to- PDF pipeline end to end. (1) doe_trial_slot_t had no integrity check of its own -- 64 slots share one devblock via a read-modify-write, so a crash mid-write to any slot could silently corrupt its siblings with nothing to catch it. Added an 8-byte CRC (same discipline the control header already had), computed/verified the same way. (2) The campaign itself had no crash-resume -- a reboot always restarted the whole 18-trial loop from index 0 even with good persisted data already on disk. Since the trial matrix is fully deterministic from (seed, n-reps), resuming needs no persisted "which trials ran" state, just a count: DOE-RESUME-COUNT (new kernel primitive, same pattern as DOE-PERSIST-TRIAL) walks the ring counting CRC-valid records for a given ISA; MU-EXEC-CAMPAIGN's signature changes to accept a start-idx and seeds MU-RUN-ID/the DO loop from it. Each RUN-*-CAMPAIGN entry word now calls DOE-RESUME-COUNT before launching. Both block-namespace-checked to fit existing headroom before committing to the design -- no new blocks needed. Real bug caught by the build, not shipped: an implicit compiler-inserted alignment byte before slot_crc silently broke the hand-computed trailing pad size (doe_trial_slot_size_check failed to compile). Fixed with an explicit alignment field, matching log_slot_t's own zero-implicit- padding discipline. extract_doe_region.py now verifies both CRCs with the REAL CRC-64/XZ algorithm from block_subsystem.c's compute_crc64() (ported and verified bit-for-bit against a native C reference this session), replacing §XXXV.11's incorrect guessed implementation. Verified: clean compile on all 3 ISAs (amd64/aarch64/riscv64 -- amd64 verified via isolated build only, not boot, since the real per-ISA campaign is currently live on the only QEMU instance this project's own rule allows), both capsules pass mkcapsule --lint, CRC64 bit-exact via native reference. Live boot-verification explicitly deferred until that campaign finishes or is interrupted -- not claimed as tested when it wasn't. Found (not missed) a real compatibility consequence: the running campaign's data is in the old pre-CRC format, so it reads as "corrupt" under the new extractor and DOE-RESUME-COUNT will resume it from 0, not mid-campaign -- no data loss, cheap redundant re-run of ~1-2 trials.

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).
