Punch list §25 item 4.1 complete. Replaces the round-robin hotwords cache with Stadium density-ranked admission/eviction on the kernel side, via the §17.7 reservoir mechanism and a kernel-side word_id -> cell_index map (no DictEntry change, dict_hash untouched). Adds stadium_birth_hera() to close the cell-0 panic hazard, STADIUM_WORD_HEAT_QUANTUM/STADIUM_WORD_COOL_RATE_Q48 Kconfig knobs (flagged untuned), and a stadium_word_forget() FORGET coherence hook to close a recycled-word_id aliasing gap. Verified: all five hotwords_cache_* call sites in dictionary_management.c bypassed under __STARKERNEL__; word dispatch feeds the Stadium at all three vm_core.c physics_execution_heat_increment() sites; hosted make unaffected; all three architectures booted to ok> with matching dict_hash (0x3d4e1daf289da94f) and matching conservation stats (promotions=354 evictions=0, resident_sum=65536 reservoir=0 sum=65536).

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.
