**Motivations:**
- Keep Collatz proof documents citable and logically consistent with repository artefacts
**Root causes:**
- Run transcript and discussion pasted into proof text
- Global closure stated as fact without explicit discharge of H_ext(M)
**Correctifs:**
- Remove pasted transcript from conjoncture_collatz.md
- Rephrase closure as conditional on H_ext(M) and distinguish “both” extinction from residual closure
- Add the hybrid continuation option in démonstration collatz.md
**Evolutions:**
- Add fixKnowledge entry documenting the issue and remediation
**Pages affectées:**
