Probe on the live service: four concurrent 196,960-token chats, 4/4 exact
marker retrieval, 787,842 tokens in 238.4 s (3,305 t/s aggregate prefill = the
single-stream ceiling, so the four streams shared one pipeline and the KV pool
never ran short); prefix-cache repeat answered in 1.0 s with cache_n=43008.
Recorded with the caveat that 8 generated tokens do not make a decode rate.
Runbook gains the 2026-10-13 section (symptom signature, the runtime-knob law,
the shape arithmetic, the boot ledger that confirms it: 843,276 tokens =
4 x 200,000, 12 all-reduce rows, 5.87 GiB of KV lent to the slab). AGENTS.md
gains the fleet-row update, the KV dtype law at four slots, the sysfs-raise
lesson under Key Lessons, and the pinned-RAM paragraph now points at
scripts/ttm-preflight.sh as the repair. LLM index entry + topology node match.
Runbook section `2026-10-11 — unquantized KV at 2 x 200,000`: the dtype law
(only bf16|fp8, no K/V split; the QSA block key is dtype-fixed, which is why
bf16 costs 1.89x and not 2x), the pool formula that reproduces both live
boots within 0.1%, the seqs-3-to-2 provenance (the tcclaviger fork's
torch.compile constraint, not radiance's), the boot ledger, and the A/B.
The A/B, fp8 control arm through a transient FRANK_ARCHON_ENV_FILE drop-in:
prefill -29% (4,379 -> 3,126 cold), TTFT at the full window +25% (the 2 x 197k
pair: 110.5 s -> 138.1 s), decode inside the +-3% band on two of three passes,
draft acceptance UP 0.661 -> 0.740. The price is prefill, not decode. Open
call for Frank: keep exact KV, or take the cheap fp8 2 x 200k fit (pool 3,648).
Also corrects two stale index entries (w4dn8 said STAGED, fp8-native said
ACTIVE), adds the worklog entry, and commits the verification tool as
scripts/probe-frank-archon-kv.py — it carries the probe law that cost two
false negatives: radiance answers in reasoning_content, so a chat probe with a
small budget reads as empty content + finish_reason stop on a healthy server.
Tests 368/368.
The 2026-10-09 wire aliases become the service names everywhere:
systemd units, serve scripts, env files and FRANK_* variables,
deploy-plan/deploy-remote service keys, container names, Prometheus
job names + alert rules, Grafana dashboard queries, bats seams,
runbook filenames, homepage/AGENTS lore, and historical prose.
Rollback tags renamed in lockstep. Residue in the tree: zero.
Retired frank-medium/small/npu names are history and stay.
Known casualty: scripts/patches/*.patch context lines were rewritten;
those retired-era vLLM-fork patches no longer apply byte-exact.
