What's Wrong?

Summary

Every background-agent worker spawned by the on-demand daemon crashes immediately
with exit 1 before init. The Agents view and claude --bg are completely
unusable — no background session can start, and existing ones can't be resumed.
Interactive claude is unaffected.

Ruled out
Not auth. The daemon separately hit auth_required (expired OAuth, headless
daemon can't refresh). Re-login + daemon restart fixed auth — the fresh daemon
authenticates cleanly — but workers still crash identically.
Not a version regression. First seen on 2.1.142; Apparently fixed on Issue #59638 (https://github.com/anthropics/claude-code/issues/59638) but it still persists on 2.1.178 (Current latest)

Existing Chat
Select a chat which is either in progress / needs input / done in agent view
Chat cannot open, with error

That session ended — back to the list
