- word_id_map / recycled_word_ids are heap tables (one shared capacity, 64 doubling), grown all-or-nothing by allocate-copy-free. Numbering is unchanged, so boot parity is unchanged. - vm_create_word() takes the id before linking; on failure it frees the entry, sets vm->error, logs LOG_ERROR and counts (vm_dictionary_word_id_refusals()). No word runs with WORD_ID_INVALID. - Readers of the id space bound by vm->next_word_id, not DICTIONARY_SIZE. - transition_heat gets its own capacity and grows on record (was sized once -- a heap overflow under a dynamic bound); every reader bounds by it. - Stadium id->cell rows start empty and grow on dispatch; a failed grow is logged, counted and not admitted. S-2 (the cell pool) stays open. Probe (reverted), identical on amd64/aarch64/riscv64: +2000 words get real ids (capacity 4096); a word at id 2738 lands 200x in the rolling window and is Stadium-admitted; FORGET recycles across the old boundary; an injected grow failure refuses the word whole (NULL, error, counter, dictionary unchanged) and the retry succeeds. 3-ISA acceptance passes; boot parity (531, 0x572daac83b797332) and the dict_hash set unchanged.
