Every portal CLI turned HTML into text with a bare tag strip, so the text inside comments, <style>/<script> blocks and hidden or display:none elements came out as visible text. Unicode tag characters, bidi controls and zero-width characters passed through untouched, raw from the portal's JSON or decoded from numeric entities. A listing could carry an instruction that renders as nothing on the page but reads as text to the model. Each CLI now runs HTML through visibleHtml, extending the helper jobindex already used for one of its page shapes, and strips invisible characters at the one function every output format reads. The /add-portal contract names both, with linkedin-search as the copy source. Each CLI's tests/hidden-text.test.ts drives the real path (the CLI in a fresh process, the command handler, or the normalizer the handler calls) and fails on master.
