Read-only until authorized
No file changes before explicit repair authorization. If you reject the conclusion, it stays read-only and tests a new hypothesis.
WORKFLOW 02 / 05
Reproduce a failure, find its root cause, then repair when authorized.
State the expected versus actual behavior, then build the fastest, most deterministic reproduction signal.
Observe the failure with your own eyes first, then strip it down — test one falsifiable hypothesis at a time.
After authorization, the first write must be a regression test. Watch it fail (red) before any production code may change (green).
Add only the adjacent cases that prevent the same class of regression — never grow a fix into a redesign.
Re-verify the original symptom and report the root cause, evidence, fix, and remaining uncertainty.
No file changes before explicit repair authorization. If you reject the conclusion, it stays read-only and tests a new hypothesis.
The first write after authorization is the regression test, and its failure must be observed. No probe or workaround can bypass this gate.
Each observation is chosen to distinguish between hypotheses — never change two variables at once.
