Tessary cases

A case is Tessary's unit of investigation. Classifiers produce findings, triage runs on those findings, and the ones ruled real issues turn into cases, each with a lifecycle to open, work, and resolve.

A case contains what moved, by how much, and since when, in the detector's own numbers. It carries the triage ruling in prose, with a confidence and its citations, and says which lane ruled it: from trace evidence alone, or grounded in the repository, where the citations are file paths you can open. It also holds before and after exemplars, real traces from each side of the shift, so you can see what the numbers look like in practice.

From a case, Tessary runs root cause analysis: an agentic session in a fresh E2B microVM over the failing cohort, with the trace evidence, a dossier, and the connected repo. It returns grounded hypotheses plus the checks it ruled out, cites the files involved, and raises a PR with the fix after attribution.
