**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 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/
