**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:**
- Instrument the C3 “final lock” as a citeable deterministic artefact
- Provide a reproducible check over Lift(B12) at palier 2^13 using D8/Fusion witnesses
**Root causes:**
- C3 lacked a machine-checkable artefact aligned with the run-report standard
**Correctifs:**
- Add a deterministic verifier that checks fusion witnesses (m<n and U(m)=U^t(n)) and aggregates N* where computable
**Evolutions:**
- Version C3 verification artefacts under docs/artefacts
- Add run report profile c3_local_descent (sha256 + metrics)
- Document the new profile and reference the artefacts in the proof plan

**Motivations:**
- Make Lemma C2 assertions citeable without terminal transcripts
- Provide a deterministic check for “both-children residual” and projective projection to B12
**Root causes:**
- C2 relied on narrative links between completion docs and B12 invariance without a machine-checkable artefact
**Correctifs:**
- Add a deterministic verifier that checks set equalities and projections from the existing completion MD sources
**Evolutions:**
- Version C2 verification artefacts in docs/artefacts
- Add a run report profile (sha256 + metrics) for C2 projective verification
- Update the proof plan with explicit C2 statements and references

**Motivations:**
- Prevent citing local H6 reports with inconsistent paliers
- Make expected vs certified palier explicit in generated reports
**Root causes:**
- Certificates can be produced from CSVs where the palier is not encoded in the class column name
- Reports did not surface palier expectations vs certificate metadata
**Correctifs:**
- Add an explicit audit section comparing artefact expected palier to certificate palier
**Evolutions:**
- Document the palier audit in report format and generator docs
- Record observed uniform bounds (Δm(E), max fusion horizon) in the proof plan as audit facts

**Motivations:**
- Avoid one-profile-per-state duplication for local H6 completeness checks
- Reuse a single strict verifier for any versioned local H6 artefacts set
**Root causes:**
- The initial local_H6_E1 profile was state-specific and not reusable for other E
**Correctifs:**
- Factor local H6 verification into a generic union-vs-lift equality check
**Evolutions:**
- Add `local_H6` profile with `--local-h6-artefacts-dir`
- Keep `local_H6_E1` as a stable alias to the E1 artefacts directory
- Document the generalized usage and update the E1 report output

- docs/features/collatz_run_report_generator.md
- docs/collatz_run_report_2026-03-09_local_H6_E1.md
**Motivations:**
- Make H6(E1) artefacts citeable/reproducible in-repo
- Generate a standard report without relying on ignored OUT/
**Root causes:**
- applications/collatz/out/ is Git-ignored, so local artefacts cannot be versioned there
**Correctifs:**
- Add strict set-equality check for H6(E1) lifted domain coverage
- Canonicalize H6(E1) artefact paths in the audit and plan
**Evolutions:**
- Add `local_H6_E1` profile to the run report generator
- Document the new profile in run report docs

- docs/collatz_run_report_2026-03-09_local_H6_E1.md
**Motivations:**
- Start C1 with a concrete state E1 and a citable local-completeness (H6) target
- Support run reports beyond D18→D21 (section 7 validation)
**Root causes:**
- C1/H6 lacked a first explicit state-level coverage target
- Run report automation was limited to the extend pipeline
**Correctifs:**
- Add an explicit H6(E1) lift coverage plan with certified D/F semantics
**Evolutions:**
- Extend the report generator with profiles (extend_finale, validation_section7)
- Document the new profile usage in docs/ and docs/features/
