Semester 1 Common Failure Modes
| Failure | Required repair |
|---|---|
| Prove a false statement without checking the base | Counterexample, repaired claim and complete proof |
| Treat a necessary graph condition as existence | Explicit witness or sufficient-condition argument |
| Approximate an event outside deterministic bounds | Sample-space bound before any approximation |
| Mistake dependence for independent sampling | Revised model and uncertainty calculation |
| Read a small residual as a small forward error | Condition-number example and error definitions |
| Claim a timeout proves no solution | Unknown status or complete finite-domain certificate |
| Pass by averaging across weak domains | Per-gate repair and fresh changed-case attempt |
| Complete reading without inspectable work | Reproducible artifact and unaided explanation |
| Report expected measurements as observed | Run record with environment or explicit pending status |
| Compress work to fit a semester label | Revised schedule from actual hours and retention needs |
During review, choose the highest-risk failure in your own evidence. Record the original attempt, correction and a fresh check. Do not invent mistakes to meet a quota. Use the rubric for the progression decision.
