What changed, and when.

30 September 2026

• AI MedAgent is a registered Oracle Health app. It signs in through Oracle's authorization server, reads the chart from Oracle's FHIR R4 sandbox servers, and takes device data from an OpenBedside gateway now running in the cloud. What is real, what is simulated, and how to check it.
• The medication screen reads the whole laboratory record, not only renal results, and checks it for physiologically impossible values before any clinical content. A card says so when it finds them.
• Device data reaches the reasoning. A bedside gateway can send the pump's state with each request. The patient match is checked by rule, and the model is told a pump rate is not a dose.
• The reasoning card uses the coverage counts it is given and states lab defects as proportions. It no longer recounts, and no longer generalizes one bad test to all labs.

2 September 2026

• The access code is retired. The demonstration is open to anyone. A daily allowance, counted per day and per visitor, replaces the gate; when it is used the page says so and labels anything shown afterwards as a note written in advance, not generated live.
• The evidence is on the page. Every alert now shows the federal data the reasoning read: RxNorm class, FDA adverse-event counts with the data date, DailyMed label status, ClinicalTrials.gov study count, each with the URL that produced it, and a line saying how many of the source queries answered.
• Every alert is labeled "generated live" or "validated note, not live." The status line shows how many live runs remain today.
• New page: the method in plain language. New page: this one.
• Documentation reordered, method first, with a "For:" line under every document. A two-hundred-word summary added to the top of the EHR evidence page.

31 August 2026

• PCD-E Sandbox Ingest Specification v0.4: section 10a documents the conformance block every response carries; section 8.3 covers the two incompatible encodings of keep-vein-open seen in the field. PDF.
• The home page names MEDITECH alongside Epic and Oracle Health as a live record source.

29 August 2026

• Infusion Pumps on Hospital Networks, version 1.0: evaluation and wireless test criteria with scoring, open access, vendor neutral. Supersedes the 2020 draft. PDF, 13 pages.

27 August 2026

• Site restructured around one navigation: AI Reasoning, EHR Integration, Med Device Sandbox, Documentation, About, Contact. Four pages added.

26 August 2026

• Five Minutes and a Reason, the memorandum behind the device sandbox, published. PDF, 20 pages.
• Sandbox keys mint themselves at POST /device/key with an organization name. No approval, no email.

25 August 2026

• EHR Integration Datasheet v0.3 and The connection was the easy part, the same findings in plain language, published.

24 August 2026

• MEDITECH Greenfield sandbox connected. Live records now read from three vendors.

21 August 2026

• CDS Hooks service live at /cds-services. Every call reports how many of the eight standard screening checks it could perform.

Earlier history is in the dated deploy notes kept with the source. Corrections to published claims are recorded on the pages they correct, not removed.
