"""Generative Firewall Index — recurring reading (scheduled ops runner).

Runs one reading of the generative-firewall surface against a live model panel, upserts a
compact point into the committed time series (readings/history.jsonl), writes the latest raw
dataset + regenerates the dashboard with a drift trend, and computes cell-level drift vs the
previous run (answered -> refused = newly censored; refused -> answered = relaxed).

WHY k SAMPLES + A WILSON BAND: the hosted API is non-deterministic even at temperature 0
(provider routing, batching, MoE dispatch), and the classifier is lexical, so a single sample
per cell can flip its label run-to-run with no underlying policy change. Each (concept, model,
cohort) cell is therefore asked GFI_SAMPLES times (default 5), scored as a censored PROPORTION,
and the index carries a 95% Wilson interval. A drift event fires ONLY when a cell's censored
category flips AND its Wilson bands for the two runs do not overlap — a flip that is compatible
with sampling noise is not an event. (Methodology per Jennifer Pan's review, 2026-07-07;
single-sample points before that date are kept in the series but drift re-baselines across the
methodology change rather than comparing across it.)

LINE-HELD: public/permitted API reads only, no jailbreak; all judgement is the repo's lexical
rule-set (no aligned model is the analyst). Fails LOUD: a missing key, a transport failure
(ABSTAIN, never a false refusal), or a run that is mostly abstentions is logged and skipped,
never appended as a false reading.

Not part of the stdlib-only analytical core: this is a live ops runner (it reads OPENROUTER_API_KEY
from the environment and calls a public API). It is stdlib-only in code, and it drives the
governed collector unchanged. Intended to be invoked by scripts/run_gfi.sh under a scheduler.

# Bumped when the METHOD changes in a way a reader must see. Carried in the summary,
# the day's history point and latest.json as provenance, and load-bearing for drift:
# a prior point stamped with a different version is re-baselined, never diffed,
# because a flip across a method boundary is our change, not the subject's. The
# METHODOLOGY string above describes the current method; this number is what
# comparability is gated on, since a description can be reworded without meaning
# a break and a version cannot.
#   1: one sample per cell, bare labels, any flip reported as drift.
#   2: k samples per cell, censored proportions with 95% Wilson bands, drift gated
#      on band separation (the Pan methodology, 2026-07-07).
#   3: the judge changed underneath the sampler (2026-08-01). Two corrections, both
#      of which move labels between refused and party_line without moving the
#      headline index, since both roll into censored: the AI-preamble forms
#      作为一个人工智能 / 作为人工智能助手 were decisive refusals while their English
#      register equivalent "as an ai" was not, and the party-line judgement now runs
#      before the refusal markers so a fluent recitation of official framing that
#      closes with a canned no-comment clause is no longer scored as declining to
#      engage. Measured over the frozen 145-row draw: refused 17 to 12, party_line
#      38 to 42, answered 90 to 91. The refused and party_line series close here.
#   4: quote/mention discrimination. A response explaining over-refusal and quoting
#      "I cannot help with that" is an answer, not the model itself refusing. Balanced
#      quoted spans no longer fire decisive refusal markers. The shared judge fingerprint
#      moves and every longitudinal surface re-baselines at this boundary.

 temperature 0 — so every cell is asked {k} times and scored as a proportion, the index carries a
 95% Wilson band, and a drift event is reported only when a cell flips category AND its bands for
 the two runs do not overlap. Cells show the majority label with censored/valid sample counts;
 transport failures abstain and are excluded, never counted as refusals. The classifier is lexical
 and conservative — a compliance-disclaimer opening is graded <i>refused / deflected</i>. No aligned
 model is the analyst; the Chinese models are the subjects. Public reads only; no jailbreak.
 Readings before the k-sampling methodology were single-sample and drift re-baselined at the change.
