- Line 19: Update the color variables and affected selectors so `.label` and
`.principles span` use separate text colors with at least 4.5:1 contrast against
`--paper` and `--white`, respectively. Replace the single ochre `:focus-visible`
outline with a higher-contrast or two-color indicator that achieves at least 3:1
contrast against the surrounding background.
In `@guides/train-your-agent-playbook/index.html`:
- Around line 384-385: Update the Perplexity description near the heading to
narrow its capability claim: replace the statement that it is not infrastructure
for deploying an agent with wording that identifies it as not a self-hosted
model-serving platform, while preserving the existing web-search, citation, and
RAG link context.
In `@index.html`:
- Line 6: Update the title in directory/index.html to match the homepage title
“AI Mastery — Field Guides and Learning Systems | Mason Nguyen”, replacing the
stale “The Architecture of Intelligence” label while preserving the existing
HTML structure.
In `@scripts/validate-editorial-expansion.mjs`:
- Line 30: Update the canonical-link validation around requireText to parse the
canonical href and compare its URL value exactly with route, rejecting query
strings, suffixes, or other deviations. Follow the existing exact-comparison
approach used by audit-live-site.mjs rather than checking only a string prefix.
In `@styles.css`:
- Around line 233-234: Increase the contrast of .field-work-meta text and its
strong status text to meet the 4.5:1 target on light card backgrounds,
preferably by darkening `#6f7974` and `#9a6a24` while preserving the existing layout
and typography.
- Line 32: Update the global :focus-visible rule to use a focus indicator that
provides sufficient contrast against both light and dark surfaces, either by
selecting a darker color than var(--acid) or by adding a two-color focus ring
while preserving the existing outline offset.

Raise contrast for labels and the focus indicator.
.label uses --green at 11px. Its contrast on --paper is about 4.1:1. .principles span uses --ochre at 11px. Its contrast on --white is about 2.6:1. The ochre :focus-visible outline is about 2.3:1 on --paper. These values are below the 4.5:1 normal-text target and the 3:1 minimum focus-indicator contrast. (w3.org)
Use separate high-contrast text colors for light and dark surfaces. Use a higher-contrast or two-color focus outline.

site:docs.perplexity.ai Sonar API Agent API web search tools third-party models official documentation
💡 Result:
The Sonar API has been deprecated and replaced by the Agent API, which serves as the unified interface for Perplexity's agentic workflows and model interactions [1][2][3]. Sonar Chat Completions will be supported until September 27, 2026 [1][2][3]. Key details regarding the transition and the Agent API: Agent API Capabilities: The Agent API offers advanced agentic features, including built-in web search, URL fetching, code sandboxing, and MCP (Model Context Protocol) servers [1][4]. It allows access to Perplexity's native models as well as leading third-party models from providers such as OpenAI, Anthropic, Google, and xAI, all through a single interface [4][5]. Web Search Tools: Unlike the legacy Sonar API, where web search was always enabled, the Agent API requires you to explicitly add the web_search tool to your request [2][6]. You can configure this search with various filters, including search_recency_filter, search_domain_filter, and user_location, to refine the source data [6]. Migration from Sonar: The Agent API uses a different request structure. While Sonar used a messages array for chat completions, the Agent API uses an input field and returns a typed output array containing both text responses and search sources [1][2]. Developers are encouraged to transition to the Agent API to leverage its increased performance and support for complex, multi-step research tasks [1][2]. Official Documentation: For implementation details, migration guides, and the full catalogue of supported models, refer to the official Perplexity documentation at docs.perplexity.ai [4][5]. Integrations with tools like LiteLLM are also supported, allowing you to route requests through the Agent API to third-party models while utilizing Perplexity's tool orchestration [7].

Narrow the Perplexity capability claim.
Perplexity’s Agent API supports web search, tools, and third-party models. Replace “not infrastructure to deploy your own agent on top of” with “not a self-hosted model-serving platform,” or link the API boundary explicitly.

Use a focus ring that contrasts with both light and dark surfaces.
:focus-visible now uses var(--acid) (#d2a04a) globally. That color is below 3:1 against the light page and field-work card backgrounds, so keyboard focus is difficult to see there. Use a darker focus color or a two-color focus ring. W3C requires sufficient contrast between focus indicators and adjacent colors. (w3.org)

Increase contrast for field-work metadata.
The new 8px metadata uses #6f7974 on light card backgrounds, below the 4.5:1 text contrast target. The #9a6a24 status color is also below that target on the non-featured cards. Darken these colors or increase the text size and weight. W3C defines 4.5:1 as the minimum for normal-sized text. (w3.org)
