# Omd Lab 01 Designmd Impact

> Archived DESIGN.md impact experiment compatibility gate. Use when an old Lab #01 run is requested, but do not generate new legacy 9/12-section documents; direct new experiments to the Core v2 benchmark track.

# OmD Lab #01 — archived writer gate

`CORE_V2_LEGACY_EXPERIMENT_BLOCKED`

The historical Lab #01 playbooks authored retired 9/12-section DESIGN.md files.
They remain evidence about an earlier format, not a valid template for new runs.
Do not create, update, or normalize a DESIGN.md through those playbooks.

For a new format-impact experiment, preregister arms against DESIGN.md Core v2:
model-only, standalone Portable Core, and an adopted Bound System where relevant.
Use the same sealed prompt/model/effort/budget and keep full-harness comparisons
separate. A new visible document must have a clean top and the exact seven Core
anchors, keep unknowns absent, and be useful without OmD or sidecars. Only an
adopted `profile: portable-core` manifest may make its graph canonical.
