audit-ui-states — Unhappy-path state matrix

Degree of freedom: MIXED — Phases 0–1 [HIGH freedom]; Phase 2 live force [LOW freedom — run exactly]. Read protocol-browser-anti-stall before any browser work.

Read-only. Map every meaningful screen against the states it can be in. Flag blank boxes, infinite spinners, raw error objects, and broken overflow.

Happy-path-only UI is the signature of generated code: it looks finished in the demo and falls apart the first time a list is empty or a request fails.

Present the matrix first. Implement only on approval.

Before any browser work, read protocol-browser-anti-stall.
