01 / The creation
What it is, and why.
Seyrin turns inbox requests into tasks, applies sender and risk rules, and uses OpenAI to write documents or make approved code changes. Kane CLI checks the result in a real browser and feeds failed steps back to the agent for up to three attempts. The inbox keeps the result, evidence, audit trail, and reply draft together. This local prototype uses fictional email and local documents; it has no live email integration, and its policy filters and browser verdicts have limitations.
02 / The harness
How Kane checks it.
The team didn't break the harness into stages.
03 / Evidence
What actually ran.
Verified means a passing run reported through a paired, verified channel. A failing run is a detection, not a confirmed bug. Everything else is as the team reported it.
