Greptile Summary

The PR adds an unlisted article explaining Claude’s planned text watermarking and C2PA provenance support.

• Adds the Markdoc post and associated AVIF cover.
• Updates the image optimization cache.
• The unlisted post is still included in the public RSS and JSON feeds.

Confidence Score: 4/5

The feed exposure should be resolved before merging if this article is intended to remain unlisted from public discovery surfaces.

The post is excluded from the normal blog listing but is still emitted by both public feed endpoints because they consume the raw, unfiltered post index.

Files Needing Attention: src/routes/blog/post/claude-ai-watermarking/+page.markdoc, src/routes/blog/rss.xml/+server.ts, src/routes/blog/feed.json/+server.ts

Important Files Changed

Filename	Overview
src/routes/blog/post/claude-ai-watermarking/+page.markdoc	Adds the article with valid author and internal-link metadata, but unlisted: true does not prevent publication through the blog feeds.
.optimize-cache.json	Adds the corresponding optimization-cache entry; the source-extension difference is intentional under repository conventions.
static/images/blog/claude-ai-watermarking/cover.avif	Adds the cover asset referenced by the post frontmatter.

### Issue 1
src/routes/blog/post/claude-ai-watermarking/+page.markdoc:11
**Unlisted post leaks into feeds**

When the RSS or JSON feed is generated, `unlisted: true` is bypassed because both endpoints consume the raw post index, causing this post to remain publicly discoverable and distributed to feed subscribers.
