Confidence score: 3/5

In docs/ja/5-CONFIGURATION/environment-reference.md, the SURREAL_USER/SURREAL_PASSWORD table formatting is broken and the default credential is documented as oot, which can lead users to misconfigure auth and fail to connect — fix the table rows and correct the default to root before merging.
Across multiple Japanese docs (for example docs/ja/3-USER-GUIDE/creating-podcasts.md, docs/ja/3-USER-GUIDE/adding-sources.md, docs/ja/5-CONFIGURATION/mcp-integration.md, and similar), the 原文 relative links resolve to non-existent paths, so readers lose the source trail and trust in the docs — update the relative paths and run a link check pass before merging.
In docs/ja/1-INSTALLATION/single-container.md, using host.docker.internal without Linux guidance can cause SurrealDB connectivity failures for Linux users who follow the steps as written — add a Linux-compatible option like --add-host host.docker.internal:host-gateway (or an equivalent alternative) before merging.
In frontend/src/app/layout.tsx, hardcoding <html lang="ja"> while language can switch at runtime means metadata can be wrong for non-Japanese sessions, impacting accessibility and SEO signals — derive lang from the active locale before merging.

P3: Broken relative Markdown link to English source document. From docs/ja/5-CONFIGURATION/environment-reference.md, ../environment-reference.md resolves to docs/ja/environment-reference.md which does not exist. The English original is at docs/5-CONFIGURATION/environment-reference.md, so the correct relative path should be ../../5-CONFIGURATION/environment-reference.md.
