# Good Enough 4u0 — Supply-Side Commons
|
|
|
|
**File:** `good-enough-4u0-supply-side.md`
|
|
|
|
## Purpose
|
|
Harness leftover and salvaged materials as raw input—without making them a fragile dependency.
|
|
|
|
## Two Supply Categories
|
|
|
|
### 1. Opportunistic Salvage (One-Time)
|
|
- Shop leftovers: lumber, metal offcuts, plastics.
|
|
- Construction salvage: glass, tiles, fixtures.
|
|
- Industrial junk streams.
|
|
- **Rule:** Cannot be the essential anchor. Always list a repeatable substitute.
|
|
|
|
### 2. Perennial Secondary Markets
|
|
- Garage sales, flea markets, thrift stores, liquidation.
|
|
- Common discards: shelving, office chairs, plastic tubs.
|
|
- **Rule:** Acceptable as semi-stable source if turnover is predictable.
|
|
|
|
## Documentation Requirements
|
|
- **Material class, not brand.** (“Aluminum offcut, ≥5 mm” not “6061 from X shop.”)
|
|
- **Substitution note.** Identify what standard material could replace it.
|
|
- **Hazard check.** Call out risks (treated lumber, tempered glass, lead solder).
|
|
|
|
## Integration with Design
|
|
- Salvage = **enhancement, not anchor.** Anchors must remain plentiful COTS.
|
|
- Builders must be able to finish the design without the exact salvage find.
