From e36f6a732cde308f5c7543cd3b40af893f4f9a3e Mon Sep 17 00:00:00 2001 From: Frank Date: Sat, 17 Oct 2026 22:18:00 -0700 Subject: [PATCH] frank-dragoon: promote the A/B verification harness into the repo MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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. --- scripts/battery-frank-dragoon.py | 267 +++++++++++++++++++++++++++++++ scripts/census-frank-dragoon.sh | 70 ++++++++ scripts/trial-frank-dragoon.sh | 57 +++++++ 3 files changed, 394 insertions(+) create mode 100755 scripts/battery-frank-dragoon.py create mode 100755 scripts/census-frank-dragoon.sh create mode 100755 scripts/trial-frank-dragoon.sh diff --git a/scripts/battery-frank-dragoon.py b/scripts/battery-frank-dragoon.py new file mode 100755 index 0000000..7dba82c --- /dev/null +++ b/scripts/battery-frank-dragoon.py @@ -0,0 +1,267 @@ +#!/usr/bin/env python3 +"""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 [all|tail] + +Writes /tmp/halogen-eval/battery-.jsonl (one probe per line) and a +human summary on stderr.
