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.
Every turn now reports why it ended, how long it took and whether a goal was active.

What
Each turn now emits an end-of-turn event recording why it ended, the error kind if any, the turn count, whether it ran as a subagent, whether a goal was active, the duration in milliseconds, and the query source and its category.
Details
Failures inside the telemetry sink are swallowed and logged as a dropped event rather than affecting the turn.
Evidence

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