Recommendations
Issues Lighthouse flagged across the 190 sampled page(s), beyond the headline scores — grouped by category and ranked by how many pages they affect. Estimated savings (transfer bytes or load time) are Lighthouse's own estimates where available. Accessibility audits are intentionally omitted; they overlap with the axe-core findings on the Accessibility page.

What the Agentic score means
The Agentic (AI-readiness) score is new in Google Lighthouse (13.4+). It measures how well a page works for AI agents and assistants — the tools that increasingly mediate how people find and use government services. It checks for things like an llms.txt file (a machine-readable guide for language models), valid structured data, a well-formed accessibility tree that agents can parse, and WebMCP tool/form descriptions. A higher score means an AI assistant is more likely to understand the page and complete tasks on a citizen's behalf correctly.
It is experimental and evolving; treat it as a forward-looking signal, not a compliance requirement. Median across sampled pages: 50/100.
Gaps found on the sampled pages: Accessibility tree is not well-formed (188), WebMCP tools registered (188), WebMCP form coverage (188), WebMCP schemas are valid (188), llms.txt follows recommendations (188), `ai-catalog.json` schema is valid (188), Cumulative Layout Shift (48).
