fetch: HTTP GET of /, /pricing, /regulatory, /security, /sign-in and /dashboard, HTML stripped to text (the app is client-rendered, so hidden states never appear). - Parallel connector: full-content markdown from the hosted reader for the same public pages, captured with the connector's own tool. - Periscope: deterministic reveal (toggles, dropdowns, accordions, hover, show more, iframes, page-load API calls) on every public page, then the walker behind the login. Login performed the way a teammate does it in Steel's live view, with the app's seeded demo account. Local Chromium; the same code runs on Steel in the demo. - Matching: case-insensitive substring of the planted text; integration statuses need both the name and the status present.
