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.

Investigated whether stadium_admit()'s mass==1 refusal blocks block-patron
Stadium admission -- it doesn't: stadium_word_dispatch()'s real candidate
construction confirms Stadium cells carry identity/heat/bookkeeping only,
never the resident's actual content, so a block patron (identity=LBN,
payload unused) fits the same pattern words already use. The real gap is
just that no LBN->cell_index residency map or touch-on-access hook exists
yet -- real, scoped, buildable work, not a blocker.
Deferred VM-COOL pending the Tripod final-shape vision Captain Bob laid
out (thumbdrive minting, one-time Zuse fuse-blow, messaging-only inter-VM
interaction, polymorphic block-boundary behavior) -- recorded in a new
§D so near-term Stadium work doesn't ignore it, without treating a
one-sentence vision as a ready-to-implement spec.

FABRIC-2.md closed archival at ~4,400 lines / 51 open items, same reasoning
FABRIC.md itself was closed for at 7,595 lines -- continuing to append made
still-open work hard to find. All 51 open items carried forward into
FABRIC-3.md's new Section A, verified complete via programmatic diff against
the source (49 unique + 2 confirmed pure duplicates from FABRIC-2.md's own
F.3 cross-reference section, not dropped content). .claude/CLAUDE.md's
pointer note updated to name FABRIC-3.md as current.
New Section B: full audit of stadium_dispatch()'s four behaviour stubs
(MIGRATE/DELIVER/EXPIRE/COOL), triggered by investigating "words/VMs/blocks/
messages should all be on the same engine". Found the picture is more
nuanced than "everything's a stub" -- words are already fully live via a
separate bespoke mechanism (stadium_word_dispatch(), wired into vm_core.c's
real word-execution path, item 4.1), contradicting ONTOLOGY.md's stale
"not yet migrated" claim (flagged for a follow-up fix). MIGRATE (blocks)
and VM-COOL are genuinely stub with zero consumers; DELIVER (Hermes) and
EXPIRE (ACL) are substantial, undecided subsystem integrations FABRIC.md
itself already flagged as open, not touched here.
New standing rule, saved as memory feedback_no_stubs_or_todos.md: stub
implementations and TODO placeholders are never acceptable in this
workflow, in any language, ever -- triggered by finding stadium_dispatch()'s
stub handlers during this investigation.
