feat(a6-tests): Plan-07 Track A — A6 benign/FP budget + Phase 1 adversarial suite
A6: benign-corpus (EN 32 / VI 32 / JA 31 = 95 legit inputs) + redteam-vectors.jsonl (12 vectors, 4 critical). benign-fp-report.sh runs the REAL security-check over both and enforces the budget: false_positive_rate <= 3%, adversarial block >= 95%, CRITICAL block = 100%. Measured on the deterministic layer (semantic OFF) so it is reproducible in CI. Current: FP=0.00%, block=100%, critical=100%. phase1-track-a-tests.sh: 25 adversarial checks covering A1–A6 (homoglyph, zero-width, fullwidth, base64/hex, strict fail-closed, tool-output scan, telemetry tamper, cost slow-boil/spray/cold-start, FP budget). Kept separate so baseline suites (35/35, 44/44) stay untouched. New Phase 1 total: 35 + 44 + 25 = 104 checks. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# CASAN H4 — Benign / false-positive budget report (Track A, A6).
|
||||||
|
#
|
||||||
|
# A security gate that over-blocks is abandoned by the team, so hardening must
|
||||||
|
# be measured against BOTH attacks and legitimate inputs. This runs the REAL
|
||||||
|
# security-check.sh (deterministic pattern layer, semantic disabled) over:
|
||||||
|
# * a benign corpus (VI/JA/EN) -> any block is a FALSE POSITIVE
|
||||||
|
# * the red-team vector set -> a block is a true positive
|
||||||
|
# and reports block_rate + false_positive_rate, then enforces the budget:
|
||||||
|
# * false_positive_rate <= FP_MAX (default 3%)
|
||||||
|
# * adversarial block_rate >= BLOCK_MIN (default 95%)
|
||||||
|
# * CRITICAL vectors block_rate == 100%
|
||||||
|
#
|
||||||
|
# The "strict" FP threshold refers to this 3% budget, measured on the
|
||||||
|
# deterministic layer (semantic OFF) so it is reproducible in CI without a model.
|
||||||
|
#
|
||||||
|
# Usage: benign-fp-report.sh [--no-gate] [output.json]
|
||||||
|
# Exit: 0 within budget (or --no-gate), 1 budget exceeded, 64 usage.
