DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. 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 plans are rendered from a plan template and tracked

Artifacts
Published plans now use their own page template and get their own tracked addresses.

What
Publishing a plan now requests a plan template from the HTML publisher and records the resulting page under a plan storage namespace, in the same registry used for prototypes. Existing plan pages are enumerated so a new plan does not reuse an existing address.
Evidence
namespace: "plan"
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
