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.
The policy settings merge now correctly propagates availableModels from the first (highest-priority) policy tier into the merged view used by the allowlist checker. In the previous version this field was not forwarded through the merge, so the new enforcement system could not see it.
Evidence
Policy merge update (search for "availableModels: w[0]?.availableModels")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
