Extracted sk_hermes_send_one() from sk_hermes_publish()'s own
per-subscriber body -- one code path for both point-to-point and
fan-out delivery, so the ledger can never diverge between them.
Point-to-point addressing turned out to be load-bearing, not
incidental: sk_hermes_publish()'s fan-out sets msg->to to whichever
member it is iterating, so a negotiation message "published" to the
common channel would spuriously reach every member, not just the real
target (checked with advisor() before building the naive version).
"Over the common channel" means every VM is reachable from birth (task
3.2), not that the exchange itself fans out -- messaging.4th's own
CH-REQUEST carried an explicit `to` for the same reason.
sk_hermes_channel_request/respond/close build the mechanics: request ->
grant (creates a private channel, subscribes both parties, sends
CH_GRANT + one ACK) or NACK ("a deny is a NACK", SXLV.1 -- no separate
type); close authorized by membership alone. The grant/deny decision is
a plain caller-supplied `approved` bool -- task 3.7 replaces the call
site that produces it with a real ACL.4th query, not this signature.
Self-test covers the task's own three checks plus a sibling advisor()
flagged: an approved respond() whose channel creation itself fails
(table exhausted) must still fall through to NACK, not a silent false
grant or half-open channel -- verified by exhausting the whole channel
table and confirming the fallback.
Bug found and fixed before this was called done: the first draft
dropped a message via pending_pop() alone, without releasing it first,
leaking its Stadium heat and failing the self-test's own ledger
baseline check (logs/20260922-065946/amd64/, kept as audit trail).
Fixed and re-verified PASS on all three architectures.

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.
