Agentic LIMS demo: on-screen text, in order. Recorded 2026-10-24.

Poster: Agentic LIMS. Every result traced. Every use decided.
Title: Agentic LIMS: an agent uses lab data only as far as it can trace it (Public lab results, traced from the sample to the file; An agentic dataset over MCP, with its own gate, evidence and documents; A person approves; a model proposes, and never approves)

[8.5 s] Lab results, traced from where each sample was taken to the file it was retrieved in. / Public data: 8,542 results from the Water Quality Portal, Dane County, Wisconsin, April to June 2023.
[17.5 s] Seven layers above a map of the sites: collection, lab, results, storage, portal, retrieval, and use. / Drag to turn it. Nothing moves unless the camera does.
[23.1 s] The agent knows nothing until it connects. Over MCP the dataset says what it is and what it can do. / 11 capabilities, the policy lims/report-use, and its revision: the sha256 of the file it serves.
[34.4 s] 9 nitrate results at Lake Monona: one site, one lab, one provider, the portal, the file. / Each row traced from its site to the file, and checked.
[44.8 s] 1,667 lab samples name no laboratory. / In orange: where they came from, and that they still reached the file.
[56.1 s] The dataset's gate decides each of 778 results: 359 admitted, 172 to a person, 247 refused. / Computed values are not measurements; a sample with no lab cannot be traced; lab-flagged or provisional results need a person.
[68.3 s] 172 results need a person: 121 the lab flagged (106 past their holding time), 51 provisional. / The approval is bound to exactly these rows. The model has no way to approve.
[78.4 s] Approved: 531 admitted under a new grant, gr-0002, that replaces the first.
[84.6 s] Now in plain language: a model turns the sentence into an order. / The dataset decides, not the model.
[95.0 s] The model read it as use computed values. The dataset refused all 219 again. / A computed value is not a measurement. The assembly still has 531.
[107.7 s] Written: 531 records, each with its lineage and the decisions behind it. / Read back from disk: the sha256 matches what the dataset reported.
[118.6 s] Every node carries its documents: this lab has 6. / Its source records, the lab's notes, and the 4 method publications its results cite.
[128.2 s] The anion method, opened at the page its results cite: p. 19 of USGS Open-File Report 93-125. / PDF page 28, served by the dataset over MCP.
[141.7 s] Answered only from the dataset's passages. Every quote checked against its page. / 2 quotes, marked on the page in the viewer.
[161.7 s] Every decision cites the dataset's own evidence, and both ledgers are hash-chained. / An edited line is caught when a ledger loads.

End: Agentic LIMS. Every result traced to its source. Every use decided. Every quote checked.
