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.

Workshop artifacts get a parse and serialize fixed-point check at publish time

Artifacts

Workshop artifacts that would silently mutate on republish are now blocked at publish time.

What

Pages the verifier classifies as a workshop surface are re-parsed and re-serialized before publishing, and the publish is refused if the round trip changes anything. This catches artifacts that would silently mutate on every decision confirm, since each confirm republishes the page.

Details
  • two checks run: the round-tripped page must still pass the strict contract, and a second round trip must produce byte-identical output
  • two new violation rules, reparse-divergence and reparse-not-fixed-point, block the publish and point at the first divergence
  • only reached for pages that verify as a workshop surface; other pages are unaffected
Evidence

reparse-not-fixed-point

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