Local master had 9 unpushed commits building block-backed DoE persistence on Artemis's own disk (FABRIC-3.md SXXXV.3/.4/.12, designed and built 2026-09-17, never pushed) that this branch never inherited after the Tripod/kernel reshuffle diverged history. Ports the mechanism cleanly onto the current Hera/Artemis/Hestia shape: - doe_region.h/.c: growable, CRC-protected trial-summary ring in Artemis's top-of-device metadata fence, immediately past log_region.c's own ceiling (devblock_from_top 98-102). Same accessor/CRC discipline as log_region.c. - log_words.c: DOE-PERSIST-TRIAL and DOE-RESUME-COUNT kernel-only FORTH words. - multiuser-doe.4th: per-ISA tagging (MU-ISA-TAG!) and campaign resume support (MU-EXEC-CAMPAIGN now takes a start-idx). - per-isa-doe.4th (new): RUN-AMD64-CAMPAIGN/RUN-AARCH64-CAMPAIGN/ RUN-RISCV64-CAMPAIGN entry points, resuming from DOE-RESUME-COUNT. - extract_doe_region.py (new): host-side reader, CRC-verified, no filesystem assumptions -- reads the ring directly off a raw disk image. Deliberately not ported: the R/LaTeX report-generation pipeline (analyse_multiuser_doe.R, multiuser_doe_report.tex, build_multiuser_doe_report.sh) -- not needed to prove persistence works, and unscoped for this pass. Verified live on all three architectures: clean boot, word_count 530->532, zero UNKNOWN WORD. amd64 and riscv64 both live-exercised end-to-end (write via DOE-PERSIST-TRIAL, count via DOE-RESUME-COUNT, clean QEMU exit, then read back correctly with extract_doe_region.py against the raw disk image -- no host serial dependency, matching the real bare-metal requirement this campaign is rehearsing for). riscv64 finding (not a defect in this port, no fix applied): DOE-PERSIST-TRIAL failed 3/3 on a first attempt against a fresh disk image with "virtio_blk: vblk_io timed out". Root cause: disk/artemis.img is a sparse file (180KB allocated of a 1GB apparent size); the new DOE region (devblock_from_top 98-102) is genuinely virgin territory on a fresh image, and riscv64's slower TCG emulation missed the existing virtio_blk spin-bound budget (already documented as fragile, FABRIC-3.md 2026-09-09) on that first cold touch. Confirmed by isolation: a plain BLOCK/UPDATE at an already-warm LBN succeeded instantly, the pre-existing LOG-ERROR" (same meta-zone mechanism, an already-warmed offset range) also succeeded, and a reboot reusing the now-partially-warmed disk let DOE-PERSIST-TRIAL succeed immediately and verify correctly on read-back. Pre-existing environmental fragility, not a logic bug in the ported address computation. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

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).
