  <h1>Delta Atlas - Ask</h1>
  <p>A fixed search engine over this page's recorded vocabulary snapshot. Ask "<b>what is X?</b>" and it finds the closest match, shows the stored definition and source assertions, and links related terms you can explore. You can also ask structurally: <b>what defends against X</b>, <b>what can go wrong with X</b>, <b>who is accountable for X</b>. One answer shows at a time. A reviewed label is not a per-term review receipt.</p>

This lists entries with a recorded review label, thin source support, or a placeholder so they can be checked and integrated with the rest. Sorting by source support only changes inspection order. A coloured dot reports a repository label; it does not prove correctness, acceptance, or an independently witnessed review.</p>

  <h1>Delta Atlas - Framework Audit</h1>
  <p>Paste a plan, framework, or project and the goal it serves. Think of the goal as the power, and each part as a wire. A solid part <b>carries the current</b> to a real outcome: it says who does what, you can test it, and something backs it up. A hollow part is a <b>broken connection dressed to look whole</b> - confident words with the current jumping the gap, an arc flash of language and nothing on the far side. This traces the circuit, shows where it breaks, names the weakest joints to fix first, and hands you a simple pattern to make them measurable. It judges structure, not subject, so it works on any topic. Heuristic, deterministic, and entirely on your device. In the atlas grammar: the framework is the <b>claim</b>; its own testable commitments are the <b>witness</b>; hollow parts are the difference.</p>

  <h1>Delta Atlas - Continuity Audit</h1>
  <p>Paste an operations manual, SOP, or workflow — one procedure per line — and the one-sentence goal it serves. Get three readings from one input: a <b>resilience</b> reading (can the manual keep the goal on track when a key person is out, a vendor fails, or an emergency hits — does it absorb, stay anchored, and recover), the <b>gaps</b> (a risk named with no stated control, single points of failure with no documented backup), and a <b>coherence score</b> (is each procedure a clear, testable action, or a vague label). Same engines as Gap Check and Framework Audit, pointed at a new domain. In the atlas grammar: the manual is the <b>claim</b>; its named backups and controls are the <b>witness</b>; brittleness is the difference. Heuristic, deterministic, entirely on your device — nothing you paste here ever leaves your browser.</p>
