The t/s ladder and the TTFT delta triple measure a configuration neither
deployed nor compared; per the purpose test they are dead weight. What survives
is the knob pricing (halving the shared chunk costs roughly a fifth of prefill
throughput), the long-prompt-only shape of the span win, and the method. Run-on
now names the era the census was taken in.
The endpoint moved to radiance 1.8.1 with MAX_SEQS=2 and the
--vram-weights-mib/--vram-kv-mib pair removed (PR #30); env, serve script and
bats carried the new shape while the page and the AGENTS.md block still
described the 1.0.13 3-slot era, so every point-of-use number was wrong.
Re-derived from the live checkout and the 2026-10-19 11:10 boot ledger, not
from the stale pre-#31 draft: runtime block (digest, version oracle, the two
CLI breaks that are boot refusals), shape table (demand-signal rows, derived
VRAM split, restored spec/batch row, host-only prefix tier, step sharing),
container contract (no /data mount), the measured 2-slot ledger, a new Eras row
for the retired 1.0.13 era whose rollback is a digest plus a trio rewrite, and
the laws: pool sizing and the per-card budget re-scoped to the pair era, a new
resolver law (funds ~90% of the worst case, host RAM below a slab step is inert,
MAX_SEQS is a demand signal), the sludge law marked measured-at-3-slots with the
fix ordered-not-verified, the knob-availability law flipped, and the slots law
now pricing the third slot in KV (4.20 -> 2.76 GiB).
