**Motivations:**
- Publish new Collatz palier runs and associated artefacts (C3 local descent, universal clauses, iteration protocol).
- Extend the scripts toolbox to generate/verify clauses and build refinement certificates over S_m.
**Root causes:**
- Universal clause witnesses were lifted to 2^(A+1) even when the witness is already fixed modulo the domain palier, leading to unstable or unnecessarily weak/ambiguous modulus choices.
- CSV palier inference in scission could mis-detect short column names (e.g. "m") by substring matching.
**Correctifs:**
- Lift D_exact/F witnesses to m_stable := max(m, A+1) in universal clause extraction and run reports.
- Make scission palier/m column detection exact-match to avoid false positives.
- Update C3 local descent verification/reporting to use strict fusion witness selection prioritizing lower modular stability and refreshed D/F metrics.
- Add a dedicated run report profile for per-palier universal clauses.
**Evolutions:**
- Add scripts for terminal clauses and minorated descent clauses over S_m, their deterministic verification, and multi-level refinement certificate building.
- Add modular tooling for register_K and incremental comparison of D_minor families.
- Add/update feature documentation for the new pipelines and generated reports.

**Motivations:**
- Support deterministic iteration beyond 2^13 with palier-scoped artefacts and reports.
**Root causes:**
- C3 palier runs needed distinct report naming; universal clause reports referenced a hard-coded C3 input.
- Palier iteration lacked a deterministic way to mass-generate local H6 run reports and keep `local_H6_index.md` consistent.
**Correctifs:**
- Add `c3_local_descent_palier` report profile (distinct filename per palier) and fix C3 report wording to use the actual palier.
- Make `universal_clauses` report profile derive its C3 input from `clauses_universelles.json`.
**Evolutions:**
- Add `collatz_generate_local_h6_run_reports.py` and extend `collatz_iterate_palier_protocol.py` to include C1 reports + palier-scoped universal clause outputs.
- Update documentation and proof pointers for palier2p14 artefacts/reports.

**Motivations:**
- Cite universal clause extraction/verification as a first-class deterministic run in the standard reporting flow.
- Provide a measurable cartography of `conjoncture_collatz.md` duplication to enable later rationalization without immediate content moves.
**Root causes:**
- Universal clauses artefacts were not covered by the run report generator, making citations inconsistent with other C1/C2/C3 artefacts.
- `conjoncture_collatz.md` contains multiple repeated trunks and generic headings, preventing unambiguous internal referencing.
**Correctifs:**
- Add `universal_clauses` profile to `collatz_generate_run_report.py` parsing and reporting counts/ok from versioned artefacts.
- Add a versioned run report for the universal clauses artefacts.
**Evolutions:**
- Extend `docs/collatz_run_report_format.md` and `docs/features/collatz_run_report_generator.md` with the new profile.
- Link the new artefacts and report in `démonstration collatz.md` and `conjoncture_collatz.md`.
- Add `docs/collatz_conjoncture_collatz_cartographie.md` (livrable 1) with headings/duplication cartography and a no-deletion plan.

**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
