Frank's order: 4 slots, a 700k pool, round UP if the resolver cannot land it
exactly. The cache target is MAX_SEQS x MAX_MODEL_LEN, so the demand is
800,000 fp8 tokens; the resolver funds ~91-93 % of demand (three boots of
evidence on the endpoint page), which clears 700k, and the VRAM has to come
from the expert plane -- which has to go somewhere, so HOST_POOL_MIB moves with
it. expert_vram_floor (core/place/planner.cpp:100-104) is exactly
plane + 2 units - host_room, and the live boot ledger pins that plane at 67.60
GiB a rank (23.73 GiB floor at 44,928 of room), so 49,152 drops the floor to
19.61 GiB and leaves the cache ~6.9 GiB: enough for the whole target, with the
leftover returned to the experts.
Costs, both real: pinned host RAM 87.75 -> 96.0 GiB (the pool is pinned once per
rank) and ~3.2 GiB a card of expert residency, read over the x8 Gen5 link when
the router picks a host-resident expert. The boot ledger's vram_kv line is the
referee; if it comes back under 700,000 tokens HOST_POOL_MIB goes up 1024 and
this redeploys.
TTM_MIN_MIB 150,000 -> 162,000 for the new pin ledger (2 x pool + PLE 48,824 +
prefix 8,192 + MNBT 2,048 + the auto checkpoint store, now 40 slots of 112 MiB =
161,848 MiB), and the bats ledger guard now counts the checkpoint store because
it grows with the slot count. The two env-value assertions in that seam are
bumped with the values they guard.
