**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/

- 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
