- Permission stream failures now produce distinct, specific error strings instead of a single generic failure:
"tool permission stream closed before response received","canUseTool returned a schema-invalid permission result","tool permission request failed","tool permission request aborted". Evidence: (search for"tool permission stream closed before response received")
- UTF-8 BOM (byte order mark,
) is now stripped from file content at the point it is read, preventing it from appearing in tool results and diff output. Evidence: (search for"charCodeAt(0) === 65279")
- Sessions interrupted by daemon shutdown are now tagged
{ kind: "interrupted_turn" }separately from other interruption types, enabling the host UI to show a different recovery prompt. Evidence: (search for"interruptedByShutdown")
- Model routing telemetry (
tengu_refusal_fallback_route_declined) now reports cascade chain details:chain_length,chain_entry_index, andchain_entryon unresolvable chain entries, giving better visibility into multi-hop fallback failures. Evidence: (search for"chain_entry_unresolvable")
- The
removeAgentWorktreefunction no longer requires a git root when the worktree path is rootless; it now delegates to the newUZtsafe-remove path rather than returning a"no git root for the worktree"hard error. Evidence: String removed from old version (search for"Removed agent worktree with no git root at:"in new).
- Worktree-isolated agent shell commands that redirect git into the shared checkout are now blocked with a clear explanation: "Refusing to run it — a worktree-isolated agent's git operations must target its own worktree." Evidence: (search for
"commands from a worktree-isolated agent must run inside its worktree")
- MCP OAuth token revocation errors (
Failed to revoke replaced tokens:) are now caught and logged without blocking the token replacement flow. Evidence: (search for"Failed to revoke replaced tokens:")
