Failure Threat Matrix[6,7]
| Failure Mode | Likelihood | Est. Onset | Mitigation Strategy |
|---|---|---|---|
| Cracking or splitting along glue joints | Medium (if neglected) | Random | Regularly apply mineral oil every 2-3 weeks to keep wood hydrated. Never run in dishwasher or submerge in water. |
| Warping | Low | Random | Never soak the board in water. Store on its side or use the built-in rubber feet to ensure even air flow during drying. |
