pfr is a bash tool that identifies which Codex CLI and Claude Code Ghostty sessions died in a power cut by clustering file mtimes around the boot time, then reopens each in its own tab with the correct resume command and pinned model.

It assigns a confidence score to the detected crash cluster, skips already-running sessions via ps, writes a reusable plan JSON, and verifies reopens by polling ps before reporting success or failure. Install is a single curl-pipe-bash one-liner requiring bash 3.2+.
