+# Good Enough 4u0 — Design Passport
+
+**File:** `good-enough-4u0-design-passport.md`
+
+## Purpose
+The Design Passport is the **front matter** for every Good Enough 4u0 project. It summarizes the project, lists its central compromise, and links all supporting documents (CCC + Material Passports).
+
+## Passport Template
+
+**1. Project Title**
+- Clear, descriptive name.
+
+**2. Project Summary**
+- One short paragraph explaining what the design does and who it’s for.
+
+**3. Central Compromise Reference**
+- Link or embed the CCC; one-sentence summary of the defect.
+
+**4. Materials**
+- List of *Anchor COTS* parts.
+- List of *Ship-Light* custom parts.
+- List of *Salvage / Non-Standard Materials* (with links to Material Passports).
+
+**5. Tools Required**
+- The *Tool Floor* (minimum necessary tools).
+
+**6. Status**
+- ☐ UNVERIFIED
+- ☐ PEER CHECKED
+
+**7. Version**
+- v0.x
+
+**8. License**
+- “This design is free to use, remix, commercialize, or ignore. No restrictions.”
+
+## Folder Structure Example
+```
+/project-name/
+  design-passport.md
+  certificate-central-compromise.md

+# Good Enough 4u0  
+### Documented Substandard Design (DSD) Template
+
+**File:** `good-enough-4u0-dsd-template.md`
+
+## Title
+*Name your design clearly and simply.*
+
+## Defect Declaration
+- **What makes this design substandard?**
+- *Example: “Uses PLA instead of ABS, so it softens under heat.”*
+
+## Purpose / Use Case
+- **What is this design good enough for?**
+- *Example: “Holding lightweight tools on a workshop wall.”*
+
+## Materials & Tools
+- List everything required, even if obvious.
+- Prefer low-cost, accessible options.
+
+## Build Instructions
+1. Step-by-step, minimal jargon.
+2. Include pictures, sketches, or links if possible.
+3. Note where the defect might show up in the build.
+
+## Known Limitations
+- Where and when will this design fail?
+- *Example: “Not suitable outdoors. Will deform in direct sunlight.”*
+
+## Improvements (Optional)
+- Ideas for making it better—but leave it substandard.
+- If someone wants to fix it, that’s their problem.
+
+## License
+- “This design is free to use, remix, commercialize, or ignore. No restrictions.”

+# Good Enough 4u0 — Material Passport
+
+**File:** `good-enough-4u0-material-passport.md`
+
+## Purpose
+A Material Passport documents any **non-standard** or **salvaged** material used in a design. It ensures clarity, replicability, and safe substitution.
+
+## Passport Template
+
+**1. Material Name**
+- Common description (e.g., “Plywood offcut, ~12 mm”).
+
+**2. Source Type**
+- ☐ Opportunistic Salvage (one-time)
+- ☐ Perennial Secondary Market (garage sale, thrift, flea)
+- ☐ Industrial Junk Stream
+- ☐ Other: ________
+
+**3. Physical Specs**
+- Dimensions (thickness, length, width).
+- Weight or density (if known).
+- Any markings or grades visible.
+
+**4. Substitute(s)**
+- At least one equivalent standard material.
+- Note what changes in performance if substituted.
+
+**5. Known Limitations**
+- Weaknesses, environmental limits.
+
+**6. Hazards**
+- Sharp edges, dust, treatments, coatings, residues.
+
+**7. Visual Reference**
+- Sketch or photo recommended.
+
+**8. Declared Use in Design**
+- Component/function it supports.
+- Why it was chosen (cost, availability, strength, aesthetics).
+
+## Rule of Thumb
+- **No Passport = No Approval** for non-standard or salvaged materials.
