  "summary": "On 31 August 2026, a test on hosted hardware verified that a downloadable usage statement matched its source statement and priced lines, retained a verifiable relationship to the prior statement and detected alteration. It was explicitly a usage statement, not a tax receipt. A 17 September amendment changed how the test account was funded after customer credit-changing operations were closed. This version says the amended rerun was still pending an authorized test window. The original passing result does not establish a completed amended production rerun.",
