Phase A of the identity pipeline (FABRIC-3.md §F.2/§F.16, §F.13):
- New include/starkernel/vm_identity.h: VMIdentity{owner_pubkey[32],
installed, acl_caps}, its own header per the project's "give real-shaped
data its own header" convention (VMUuid's own precedent), embedded by
value on struct VM. acl_caps is an independent capability bitmask, not
an ordered privilege tier (decided 2026-08-28) -- Zuse isn't a
structurally special VM, her identity just has every bit set
(VM_IDENTITY_CAP_ALL). No individual capability bits assigned yet,
deliberate slack matching blk_meta_t's own acl_reserved precedent --
real bits get names once the operation they gate (BINDSTEP, MINT, ...)
actually gets built.
- Applied the devblock-1 relocation decided in §F.13: new
HOMEBLOCKS_SIG_START_FBLOCK constant (homeblocks_sig.h), repl.c's
homeblocks_sig_check() call site updated from the literal 0. Also
applied the still-owed blockmap_offset/blockmap_devblocks ->
identity_src_offset/identity_src_devblocks rename decided in §F.6 (no
other code referenced the old names). Updated the header's own stale
GPT-relative doc comments to match -- GPT was dropped permanently, this
location is final, not an interim stand-in.
Verified live on all three architectures: clean compile, clean boot to
ok>, Hermes/Artemis both confirmed live with no KILL (no regression from
last session's session-less fix). One pre-existing, unrelated anomaly
observed consistently on all three arches, not caused by this change (no
code touched here intersects Zuse's own fence-write path): "Zuse: minted
but fence write FAILED (not persistent)" -- flagged for its own
investigation, not chased here.

src/
Hosted StarForth VM implementation (compiled by the root Makefile).
Bare-metal kernel sources live in src/starkernel/; FORTH word
implementations in src/word_source/; the test harness in
src/test_runner/; platform shims in src/platform/.
Entry point / interpreter core
main.c— CLI entry point, VM init, DoE mode dispatch.vm.c— interpreter loop, stacks, dictionary state (the central runtime file).vm_api.c— external VM API implementation.vm_bootstrap.c— VM bootstrap initialization.vm_debug.c— debugging utilities.vm_time.c— time-related VM operations.vm_internal.h— internal-only declarations shared across thevm_*.cfiles, not part of the publicinclude/vm_api.hsurface.repl.c— REPL read-eval-print loop.cli.c— CLI argument parsing.io.c— I/O operations.log.c— logging infrastructure.
Memory / dictionary / blocks
memory_management.c— dictionary allocator.dictionary_management.c— dictionary allocation and search.dictionary_heat_optimization.c— Loop #1 execution-heat tracking.word_registry.c— word registration system.block_subsystem.c— logical→physical block mapper.blkio_file.c,blkio_ram.c,blkio_factory.c— block I/O backends (file-backed, RAM-backed) and the factory that selects between them.stack_management.c— stack operations.
Physics-driven adaptive runtime (7 feedback loops)
physics_runtime.c— main physics coordinator.physics_hotwords_cache.c— Loop #1 hot-words caching.physics_metadata.c— per-word metadata tracking.physics_pipelining_metrics.c— Loop #4 word-transition prediction.physics_execution_hooks.c— execution instrumentation.rolling_window_of_truth.c— Loop #2 circular execution-history buffer.inference_engine.c— Loops #5/#6, statistical inference (window-width, decay-slope).ssm_jacquard.c— L8 Jacquard steady-state mode selector; consumescompudynamics.cfor tuning-word/config lookups.compudynamics.c— generic compudynamics module (cd_tuning_word(),cd_tuning_vm()); the score/UCB/reward/weight constants for the L8 adaptive table live here, not inssm_jacquard.c.heartbeat_export.c— heartbeat metrics export (CSV export function itself not yet implemented — seedocs/working/architecture/heartbeat_csv_export.md).
Math / measurement
math_portable.c— portable math functions.profiler.c— performance profiling.doe_metrics.c— Design of Experiments metrics (2^7 factorial).
Any .bak file alongside a .c file here (doe_metrics.c.bak,
inference_engine.c.bak, vm.c.bak) is a pre-edit backup left by a past
maintenance script (see scripts/remove_loop_conditionals.sh), not a
build input.
