# Good Enough 4u0 — COTS Anchor Standard

**File:** `good-enough-4u0-cots-anchor-standard.md`

## Purpose
Ensure every design has at least one **Anchor COTS** part: a globally common, indefinitely available component that stabilizes the design and makes replication realistic.

## Anchor Criteria
- **Plentiful:** Mass-produced at global scale; no single-supplier risk.
- **Future-proof:** Likely to remain in production for decades (building trades, agriculture, logistics).
- **Local availability:** Stocked in hardware stores, farm suppliers, big-box retailers.
- **Interchangeable:** Accepts substitutes (different brand, slight dimension variations).
- **Non-exotic:** No boutique, hobbyist-only, or import-only parts.

## Example Anchors
- PVC pipe / EMT conduit.
- Mosquito screen.
- Hardware cloth / wire mesh.
- Zip ties.
- Pallet straps.
- Common bolts/nuts/washers (M6 / 1/4″).

## Documentation Requirements
- **Anchor Identification:** “This design anchors on 1/2″ EMT conduit.”
- **Substitution Map:** “Can also use 1/2″ PVC, bamboo pole, or hardwood dowel.”
- **Failure Note:** Explain what changes if a weaker/stronger substitute is used.
