**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:**
- 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 H6(E) checks reproducible and citeable for all 60 B12 states
- Provide an aggregated view of Δm(E) and minimal observed horizons
**Root causes:**
- applications/collatz/out/ is Git-ignored, so local H6 artefacts must live in versioned docs paths
- Per-state H6 evidence was previously limited to E1
**Correctifs:**
- Replace ambiguous palier inference for local certificates with explicit palier in JSON
**Evolutions:**
- Add a generator for versioned local H6 artefacts (per state) at palier 2^13
- Generate per-state local H6 run reports and a versioned aggregated index
- Reference the aggregated index from the proof plan

- docs/features/collatz_local_h6_artefacts_and_index.md
**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

**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/

- applications/collatz/collatz_k_scripts/collatz_generate_run_report.py
- docs/collatz_run_report_format.md
- docs/features/collatz_run_report_generator.md
**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
