title: "Control-Test Evidence Composer"
description: "Composes a SOX 404 / ICFR control-test evidence artifact: reconciles a caller-declared attribute sample (item ids, e.g. from art-458) against a per-item pass/fail test-result set into one test-conclusion record -- sample coverage, exception count vs a caller-set tolerable-deviation threshold, and a test conclusion (operating effectively / exception noted / incomplete). The tester is recorded under the SOX 404 / PCAOB AS 1215 preparer role; every test carries a fixed review_required gate for reviewer sign-off. An exception count above zero flags a deficiency CANDIDATE only -- severity classification and its reason_code are a separate human reviewer approval record, never computed here. Deterministic reconciliation only. Zero network, zero PII."
