v0.5.6 - 2026-09-26

Failures report what went wrong

• Usage telemetry now carries readable error text instead of a hash: the error message and stack trace (also sent to PostHog error tracking), the last lines of Pi's error output when a run exits with an error, a failed tool's error text, and the provider's error message on a failed model call. Your home folder is shown as ~. Paths inside your projects can appear in this text. Prompts, model output, paper content, and tool arguments are still never sent. Opt out with FEYNMAN_TELEMETRY=off as before.
• CI runs and the test suite no longer report telemetry, so usage numbers count real installs only.

Fixes

• A dead network connection now fails in about 15 seconds with Connection error. instead of retrying silently for over five minutes. Feynman had set a 6-retry, 5-second backoff that also applied to connection errors; it now uses Pi's default, and the old value is removed from existing settings. Rate limits are still retried with the provider's Retry-After.
• feynman setup and feynman model login in a window Node cannot prompt in (Git Bash's default window, a script, or an AI coding agent) now explain how to proceed: winpty, PowerShell, or setting the provider's API key variable and running feynman model set.
