Punch list §25 item 3.3 complete. StadiumBehaviour (stadium.h) enumerates exactly the four tags §18.3 already names -- MIGRATE, DELIVER, EXPIRE, COOL -- mapped from §17.1's patron table: blocks->MIGRATE, messages->DELIVER, ACLs->EXPIRE, words and VMs both->COOL. Nothing invented; the tag set and mapping were already in the document. stadium_dispatch(cell_index, behaviour) dispatches on the tag only, never asks what kind of patron departed. Handlers are stubs -- the real actions belong to subsystems not yet migrated onto the Stadium (Phase 4). Nothing calls stadium_dispatch() yet; item 3.5 is its first consumer. The switch is exhaustive with no default case, making §13's "closed enumeration, fixed at build time" a compiler-enforced property under this project's -Wall -Werror rather than just prose. Verified live: temporarily deleted the COOL case, rebuild failed with error: enumeration value 'STADIUM_BEHAVIOUR_COOL' not handled in switch [-Werror=switch], restored it, confirmed clean again. The header's behaviour field stays uint8_t, not the enum type itself, since C does not guarantee an enum's underlying type and that field's offset is load-bearing for item 3.1's validated 64-byte layout. Verified: three-architecture boot (amd64, aarch64, riscv64), all reaching ok> with identical dict_hash=0x3d4e1daf289da94f matching the item-3.2 baseline.

Headers for the kernel-side VM subsystem (src/starkernel/vm/).
arena.h— the capsule arena allocator: fixed-region allocation for capsule payload data, separate fromkmalloc's general kernel heap.parity.h— the birth/execution parity-record logger: declares the logging interface used to record VM ID, capsule content hash, and dictionary hash on every capsule birth, enabling offline determinism verification across independent kernel runs.
