The three artifacts that produced the native-vs-swift15 verdict, so the next
payload swap starts from instruments instead of ad-hoc scripts:
census-frank-dragoon.sh — the engine's own checkpoint tools (verify/ppl/niah)
over BOTH payloads under one knob set; the pool stays 524288 deliberately
because the ppl pass scores 297,053 ids as two 262,144-token sequences.
battery-frank-dragoon.py — behavior battery against the live service: refusal
census, thinking-token census, tool-call turns, the red-PNG vision probe,
needle-in-haystack, decode/prefill/prompt-cache rates; discards the
post-boot warmup request and records the engine's 400 body (which names the
exact token overage) instead of dying on it.
trial-frank-dragoon.sh — the guarded candidate window: fetch gate, verify,
stop+mask, census, boot through a transient FRANK_DRAGOON_ENV_FILE drop-in,
battery, trap-guarded restore.

"""battery.py — the same behavioral + throughput battery against whichever

frank-dragoon boot is live, so the two boots are compared on identical traffic.

python3 battery.py <tag> [all|tail]

Writes /tmp/halogen-eval/battery-<tag>.jsonl (one probe per line) and a

Token arithmetic that shapes the probes (measured on this engine): wikitext

bills ~4.33 characters per token, so the haystacks are sized in CHARACTERS
|

against a token budget — a prompt over HALOGEN_CTX is refused with a 400 that
|
|
names the token count, and the harness's chars/4 estimate would overrun.
