What changed
LangChain introduces a small application entry point first, separates framework concepts from lower-level graph primitives, groups capabilities and patterns, and teaches through progressive code examples. Our previous docs mixed harness assertions, private provisioning, wire graphs and application examples; tutorials often began with placeholder paths. They also downloaded a full page database before rendering.
The new site renders each article to standalone HTML at build time. Navigation separates getting started, features, workflows, integrations and reference. Search downloads only a compact index; code is available without JavaScript. Language controls and copy buttons enhance the rendered article. Source HTML is sanitized during the build.
Soterias visual identity
White paper, black ink, neutral hairlines and one blue accent come from soterias.io/brand/tokens.json. Serif headings and sans-serif body follow Soterias identity. There are no copied LangChain logos, text, illustrations or stylesheets. We adopt its documentation organization and progressive teaching pattern.
New SDK features found during this work
The live release is Python soterias0.1.3 / native0.1.0rc4 and @soterias/core0.1.0-rc.4. EvidenceRepository, Citation and FactReference now support source registration/revocation, exact quotation checks, candidate interpretations, provenance and fact checks. See evidence. Recent source also includes beginner client lifecycle helpers and benchmark signer/runner APIs. These additions are preserved; Task29–30 source is not rewritten by this redesign.
