Fan-out is free. The input problem is not.

Parallel Code already races Claude, Codex, and Gemini on one task and keeps the winning diff — MIT, on your machine. GitHub Agent HQ assigns one issue to several agents and merges the best PR. Edge cannot be the button that starts four agents. The surface that still is empty is automatic extraction of a portable, decontaminated repro from a dead session, and the routing graph that would accumulate from it. Position there, or do not position.

Green is an Edge advantage. Red is theirs. Amber is parity. Every named tool here has shipped. Edge has not. That colours every row.

When this is the right call

It fits if

The failure is buried in a two-hundred-turn session you do not want to hand-summarize.
The repo cannot leave, but a sanitized repro can.
You keep hitting the same class of wall and want to know which scaffold to reach for.
You care why a patch is trustworthy, not only that one exists.

It does not if

You already run Conductor or Parallel Code and treat fan-out as solved and free.
You are on Copilot Enterprise — Agent HQ is bundled and already approved.
The failure is trajectory collapse with no crisp repro. We cannot serve that today.
You need it this week. We are pre-validation.

What can eat this

Absorption. Cross-harness retry is a checkbox for GitHub or Cursor.
Free anchor. MIT local tools set the price at zero.
Class C. A large class of dead sessions will not package. Observability vendors have documented the same decay.
