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.
Turn analysis survives a bad message and reports when it degraded
Under the hood
Useful2Signal2
Telemetry
A bad message no longer breaks turn analysis; failures are skipped and reported instead of passing silently.

What
The check for whether a turn was user-driven now catches errors per message and skips the ones that throw. If the whole scan fails it returns a default and emits telemetry tengu_turn_tail_analysis_degraded, so the degradation shows up rather than passing silently.
Evidence
tengu_turn_tail_analysis_degraded
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
