Reviewer checklist

Before merging, confirm each item below. The validator catches structural problems (raw HTML, dangerous URLs, secrets); these items need a human eye.

• Anchor text on every new link reads honestly — no click here, no link text that contradicts its target host.
• Every newly introduced external URL (listed below) points to a host you expect to see in Coinbase docs.
• Frontmatter title / description still match the page's role (reference vs. overview vs. conceptual).
• Any <Warning> added describes a real breaking change in the source PR, not a paraphrase the model invented.

Newly introduced external URLs

No new external URLs in this sync.

Unrouted source files

These files changed in the source commit but match no rule in scripts/sync-from-base-std/route-table.json, so no docs page was edited for them. Add a rule (or an ignored rule) so the next change routes on its own.

• docs/integration-architecture.md

Proposed placement (from IA guidelines)

Derived from docs/ia-guidelines.md and docs/content-guidelines.md by the sync's placement pass. Every proposed page already exists; nothing here creates a page. Turn an accepted row into a route-table rule to make it permanent.

Source file	Proposed docs page	Guideline rule	Rationale
docs/integration-architecture.md	docs/specifications/b20/index.mdx	Specification overview: Architecture / component map	This document describes the externally observable architecture of B20, its components (Factory, Policy Registry, Activation Registry, tokens), and their relationships—exactly the content that belongs in a B20 specification overview's Architecture section.
