 # NO --vram-kv-mib: it was REMOVED at 1.3.0 and naming it is a boot refusal, not
 # a no-op — verified on the pinned image 2026-10-27: "E --vram-kv-mib was
 # removed: the card is split between the weights and the cache from what the
-# model needs." The budget resolver derives that split from --host-pool-mib and
-# --gpu-headroom-mib, and this rig inherits BOTH from frank-archon.env, the file
-# that owns them: the cache's funding is `elastic - expert_floor` and the expert
-# floor falls one MiB for every MiB of host pool (frank-archon.md, Laws), so the
-# pool buys KV as well as residency — a private pair is not a free knob. What
-# buying one cost, measured on the first kldref boot the same day with the w4
-# era's 12288 / 768: "I kv: the pool backs 6% of the worst case (4 sequences all
-# at 32768 tokens), 0.2 full-length sessions; a larger --host-pool-mib gives the
-# cache more" — a 270 MiB, 7,436-position cache, after which the recorder refused
-# every one of the 197 corpus documents ("E kld: document 0 is 10554 tokens and
-# the KV pool holds 7436, so it can never be scored") and exited 1. Production's
-# 49,152 per rank is affordable exactly when the rig runs: the rig stops
-# frank-archon first, and that stop frees the same 96 GiB the service was pinning.

-# The 32,768-token window it pairs with is not up for grabs: the corpus's longest
