Robert Allan JamesandClaude Sonnet 5 d55ec3241b starkernel: item 3.1 -- the Stadium cell and header

Punch list §25 item 3.1 complete.

Defines StadiumPatronHeader and StadiumContinuationCell in new
include/starkernel/vm/stadium.h, unioned as StadiumCell per §3's
closed two-valued union. src/starkernel/vm/stadium.c added to
Makefile.starkernel's LOADER_EXTRA_SRCS/KERNEL_EXTRA_SRCS so the
header's compile-time size checks are actually compiled, not merely
included by something that never builds.

Discriminator ruled an external side bitmap (Captain Bob), not a
header field -- amended into §3 and §23.3 before this code was
written. Item 3.1 declares the bitmap's purpose/indexing in a comment
only; allocating it is item 3.2's scope.

Both cell shapes counted for real at exactly 64 bytes with zero
compiler-inserted padding (three C99-portable negative-array-size
assertions -- no _Static_assert, this project targets C99). Header
matches §23.3's original 32+32 split unchanged, since the
discriminator moving outside the cell left nothing to compete for that
space. Continuation cell matches item 1.12's 4+60 figure unchanged for
the same reason.

Verified the size assertion is actually live: broke it to 63,
confirmed the build failed with the expected negative-array-size
error, restored it, confirmed a clean compile.

Verified: three-architecture boot (amd64, aarch64, riscv64), all
reaching ok> with identical dict_hash=0x3d4e1daf289da94f matching the
item-2.2 baseline. Confirmed stadium.o present in both obj/loader/vm
and obj/kernel/vm post-build on amd64, closing the gap the item-2.2 WIP
exposed (an uncompiled header proves nothing).

Left open, not fabricated: §23.4 #2 ("does a typical message fit in
one cell") is unanswerable today -- no message patron struct exists
anywhere in this tree yet.

Design of Experiments (DoE) campaign data and analysis for the LithosAnanke kernel.

bare_metal/ — the bare-metal DoE experiment: blind full-factorial 2⁴ runs measuring the L8 Jacquard mode selector's effect on the Steady-State Machine across amd64/aarch64/riscv64. See experiments/bare_metal/README.md for the full directory layout (runs/, latest/, analysis/{charts,tables,report}).

Hosted-VM DoE campaigns (factorial/heartbeat/ablation studies) live under docs/working/experiments/ instead — this top-level directory is specifically the kernel/bare-metal side.
