Root CA + snakeoil intermediate generated entirely offline (/home/rajames/CLionProjects/lithosananke-ca/, outside this repo, private keys chmod 600) per this milestone's own requirement: Ed25519, root self-signed 20-year validity, intermediate real-CA-signed (CA:TRUE, pathlen:0), chain verified via openssl. Snakeoil intermediate embedded as a capsule (capsules/pki/ snakeoil-intermediate.der) -- confirmed the font-capsule precedent needed zero new infrastructure, any non-.4th file under capsules/ embeds verbatim already. New x509_ed25519.c: a from-scratch, narrow DER walker (not general ASN.1/X.509, per this milestone's design decision) extracting the raw Ed25519 pubkey from a cert's SubjectPublicKeyInfo -- handles the optional v3 version field, verifies the AlgorithmIdentifier OID is Ed25519 rather than assuming, handles both DER length forms. Verified against ground truth: the extracted key from the real embedded cert matches openssl's own reported pubkey byte-for-byte; refusal path checked against truncated/garbage/empty/wrong-algorithm (real RSA cert) input. Compiles clean on all three architectures. Still open: mkcapsule signing step, wiring ed25519_verify() into capsule_birth.c's three validate call sites (landing warn-only first, per decision -- a bug here could stop every capsule from birthing, including Mama's own, on all three arches), and the BLOCK_MAP.md signature-status column.

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).
See include/starkernel/README.md for the bare-metal kernel headers.
