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.

What
The routine that tallies text and thinking character counts per message now also counts blocks tagged as narration. This uses the raw signature check with no gate, so it counts on every build where the helper is present.
Evidence
isNarrationTaggedBlock
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
