Two docs updates shipped together.

1. OpenRouter response caching — examples/configuration/README.md

Documents how to opt into OpenRouter's Response Caching via extra_headers for openrouter/* models — identical-payload requests return in ~80–300ms with zero token billing (helps the compile-retry path and repeated lint/dev iteration). Reuses the existing extra_headers passthrough (top-level or under litellm:); no code changes.

2. Rendered architecture diagram — README.md, assets/

Replaces the ASCII architecture diagram under How OpenKB Works → Architecture with a rendered illustration (assets/openkb-architecture.png) covering the same pipeline: raw/ intake → markitdown (short docs) / PageIndex (long PDFs) → LLM wiki compilation → the wiki/ foundation (index.md, log.md, AGENTS.md, sources/, summaries/, concepts/, entities/, explorations/, reports/) → query/chat, the Skill Factory, and future generators.

  • Image lives in a new top-level assets/ dir — docs/ is gitignored, so README assets can't live there.
  • ~1.7MB; can compress to WebP / lower-res (~200–400KB) if preferred.

@KylinMountain
docs(examples): document OpenRouter response caching via extra_headers
7644b13
OpenRouter Response Caching (sending X-OpenRouter-Cache / -TTL headers on
compiler LLM calls) is achievable through the general extra_headers
passthrough — no dedicated config needed. Document it in the configuration
guide alongside the other litellm/extra_headers recipes.

docs: replace ASCII architecture diagram with a rendered image
31f9578
Swap the text-based diagram under "Architecture" for a rendered
illustration (assets/openkb-architecture.png) covering the same pipeline:
raw/ intake -> markitdown (short docs) / PageIndex (long PDFs) -> LLM
wiki compilation -> the wiki/ foundation -> query/chat, the Skill
Factory, and future generators.

Two docs updates shipped together.
1. OpenRouter response caching — examples/configuration/README.md
Documents how to opt into OpenRouter's Response Caching via extra_headers for openrouter/* models — identical-payload requests return in ~80–300ms with zero token billing (helps the compile-retry path and repeated lint/dev iteration). Reuses the existing extra_headers passthrough (top-level or under litellm:); no code changes.
2. Rendered architecture diagram — README.md, assets/
Replaces the ASCII architecture diagram under How OpenKB Works → Architecture with a rendered illustration (assets/openkb-architecture.png) covering the same pipeline: raw/ intake → markitdown (short docs) / PageIndex (long PDFs) → LLM wiki compilation → the wiki/ foundation (index.md, log.md, AGENTS.md, sources/, summaries/, concepts/, entities/, explorations/, reports/) → query/chat, the Skill Factory, and future generators.
  • Image lives in a new top-level assets/ dir — docs/ is gitignored, so README assets can't live there.
  • ~1.7MB; can compress to WebP / lower-res (~200–400KB) if preferred.

docs(examples): document OpenRouter response caching via extra_headers
7644b13
OpenRouter Response Caching (sending X-OpenRouter-Cache / -TTL headers on
compiler LLM calls) is achievable through the general extra_headers
passthrough — no dedicated config needed. Document it in the configuration
guide alongside the other litellm/extra_headers recipes.

docs: replace ASCII architecture diagram with a rendered image
31f9578
Swap the text-based diagram under "Architecture" for a rendered
illustration (assets/openkb-architecture.png) covering the same pipeline:
raw/ intake -> markitdown (short docs) / PageIndex (long PDFs) -> LLM
wiki compilation -> the wiki/ foundation -> query/chat, the Skill
Factory, and future generators.
