Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Published-page island parsing requires a JSON object

You'll notice
Useful2 Signal0
Artifacts

Malformed published-page data now gives you a clear message instead of a confusing schema error.

What

Staleness anchor and decisions island payloads are checked to be plain objects before schema validation, so non-object JSON produces a clear message rather than a confusing schema error.

Details
  • New messages "the published page staleness anchor is not a JSON object" and "the published page decisions island is not a JSON object".
  • The same object predicate replaced hand-rolled checks in frontmatter and plugin-manifest validation.
Evidence

the published page decisions island is not a JSON object

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
