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.
