The piece FABRIC-3.5.md SXXXIII.6 calls "what remains genuinely hard,"
built and proven first per its own recommendation. Added
src/starkernel/vm/kernel_hermes.c (wired into Makefile.starkernel's
LOADER_EXTRA_SRCS -- this repo lists vm/*.c files explicitly, no glob)
and sk_hermes_alloc()'s declaration in kernel_hermes.h.
Checks stadium_reservoir_peek(vm_id) >= SK_HERMES_Q_SLOT before
touching the reservoir at all -- refusal this way needs no rollback,
since nothing was pulled -- with an explicit rollback path
(stadium_reservoir_push) kept defensively for the pull-then-short case,
though nothing in this single-core kernel is expected to reach it.
SK_HERMES_Q_SLOT = Q48_ONE / SK_HERMES_MSG_MAX (2048), deliberately
simpler than messaging.4th's own formula, which reserves a Q.1/3 floor
for COMMON-CH's own Stadium heat -- kernel-Hermes has no such object
(SXXXIII.4/SXXXIII.5's flat membership list carries no heat of its
own), so there is nothing left for that floor to protect.
Self-test in kernel_main.c, same diagnostic-only synthetic-VM pattern
as the existing Stadium quota grant self-test (lo=3, distinct from
that test's lo=1): reads back the actual granted reservoir rather than
assuming a number, derives expected_n from it, allocates to refusal,
and checks the refusal lands at exactly expected_n, the reservoir
doesn't move on the refused attempt (rollback proven, not assumed),
and the final reservoir is exactly reservoir0 minus got_n times
Q_SLOT.
Three-arch boot clean: amd64/aarch64/riscv64 all reach [zuse@Hera] ok>,
zero UNKNOWN WORD, dict_hash unmoved from task 2.1 (pure C, no FORTH
touched). All three print identical self-test arithmetic: reservoir0=
65536 Q_SLOT=2048 expected_n=32 got_n=32 reservoir_after=0. No compiler
warnings.
Noted, not fixed: Q_SLOT's divisor and SK_HERMES_MSG_MAX are the same
32, so reservoir and arena exhaustion land at exactly the same count by
construction -- this test can't distinguish which refusal reason
fired, only that refusal is correct and rolls back correctly.
Deliberately not evidence for stadium_conserved(): allocating alone
(no release yet, task 2.3) leaves pulled heat held off the Stadium
floor, so the two-term check would correctly read false right now if
run mid-hold. That's expected, not a bug -- Stage B (task 2.7) is
defined as "before and after the alloc/free cycle," not "continuously
during." This task's self-test checks reservoir arithmetic directly
instead.
Authorized by Captain Bob ("Yes continue").

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).
