stadium_admit()'s mass==1 refusal looked like a hard blocker for 1024-byte blocks, but stadium_word_dispatch()'s real candidate construction proves Stadium cells carry pure identity/heat/bookkeeping, never the resident's actual content -- a block patron follows the same shape (identity=LBN, payload unused), so this was real, scoped work, not a case for stubbing. New stadium_blocks.h/.c mirror stadium_words.c's admission/cooling shape, keyed by (quota_slot, lbn) in a fixed-capacity open-addressing hash table (tombstone deletion) instead of a dense array, since LBN space isn't densely bounded like word_id. Wired into block_word_block()/buffer()/ update() (block_words.c), __STARKERNEL__-guarded. stadium_dispatch()'s MIGRATE case now calls blk_flush(lbn) for real instead of printing "(stub)". Three new Kconfig constants (STADIUM_BLOCK_HEAT_QUANTUM/ STADIUM_BLOCK_COOL_RATE_Q48/STADIUM_BLOCK_TRACK_CAP_MULT) mirror the word-patron ones, same three-layer wiring. VM-COOL/DELIVER/EXPIRE stay explicit punch-list items -- VM-COOL deferred pending the still-iterating Tripod/Zuse/messaging vision, DELIVER/EXPIRE are their own future subsystem integrations per FABRIC.md's own "open, not resolved" notes. Verified clean compile (zero warnings) and clean boot to REPL with conservation intact (resident_sum + reservoir == Q48_ONE) on all three architectures (amd64/aarch64/riscv64); BLOCK/BUFFER touches exercised live from the REPL with no crash; a 22,000-distinct-block flood loop against an artificially shrunk Stadium ran clean under heavy admission load. A live MIGRATE console fire was not directly observed this session (root-caused to a pre-existing reservoir-floor/density-eviction interaction unrelated to this change, documented in FABRIC-3.md) -- flagged as an honest follow-up, not silently claimed.

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).
