How-to: A/B Your Lean With a Fixed Seed

On Edge, a seed makes the result repeatable for a given configuration. That turns tuning from a guess into a fair test. Background on the matrix: part 01

1. Pick one real goal. Write it once and do not touch the wording between runs.

2. Set a seed. Any integer works. Keep it the same for both runs.

3. Run A in the default band. For most technical and strategic work the guide starts bias at 0.78–0.85. Edge defaults to 0.82.

4. Run B with only bias changed. Go higher if you want a more decisive, committed brief, or lower if you want broader exploration of trade-offs.

5. Hold everything else still: n, m, steps, grid_size, goal and extra context.

6. Read both briefs side by side. Ask which one needs less human repair before your host can use it.

Change one knob per test. If you change two, you will not know which one did the work. Once a lean band works for a type of goal, write it down and reuse it.
