Performance impact

How far pages fall short of Google's "good" benchmarks: Largest Contentful Paint ≤ 2.5s and page weight ≤ 1.6 MB. Lower is better.

Avg extra LCP over 2.5s: 13.7s 153/153 pages over
Avg extra weight over 1.6 MB: 1.33 MB 156/156 pages over

Set page_loads_per_week for this target to also estimate total wasted time and data (the way daily-dap uses traffic counts).

Recommendations

Issues Lighthouse flagged across the 153 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: 59/100.

Gaps found on the sampled pages: WebMCP tools registered (153), WebMCP form coverage (153), WebMCP schemas are valid (153), llms.txt follows recommendations (153), Cumulative Layout Shift (90), Accessibility tree is not well-formed (13).

Per-page results

Lighthouse scores and Core Web Vitals per sampled page (2026-W39). Agentic = experimental agentic-browsing score. PWA / offline readiness is tracked in the Standards tab (Lighthouse 12+ removed the PWA category). — click a column heading to sort
