**Motivations:**
- Make certificates reproducible when CSV columns do not encode the palier
- Avoid FileNotFoundError when writing certificates into new folders
- Reuse scission in the local H6 generator to avoid duplicated certificate logic
**Root causes:**
- palier inference relied on max residue value when the class column was generic
- scission assumed output directories already exist
- empty CSV fields were coerced to 0
**Correctifs:**
- Infer palier from explicit columns (palier/m) or filename, keep heuristic fallback
- Create parent directory for output JSON
- Skip empty class/sister values instead of adding residue 0
**Evolutions:**
- Use collatz_scission for certificate generation in local H6 artefacts generator

**Motivations:**
- Make the hybrid path (C1→C2→C3) operational with explicit targets
- Define R_m exactly as used by the pipeline for citable artefacts
- Keep execution transcripts out of proof documents via stable run reports
**Root causes:**
- Hybrid continuation lacked a concrete invariant/lemma agenda and a precise R_m definition
- No standardized run report format in docs/
**Correctifs:**
- Document the pipeline-level definition of R_m (D/F update rules and artefact schema)
- Add explicit prioritization and lemma targets for the hybrid trajectory
**Evolutions:**
- Add a standard run report template and a filled example with sha256 fingerprints

**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
