| File | Role | How to regenerate |
|------|------|-------------------|
| `L3-508-001-001-T1-community-topup.md` | Source of truth — edit this | Human or LLM |
| `L3-508-001-001-T1-community-topup.json` | Structured metadata for the registry | LLM regenerates from the sections above |
| `code/solver.*` | Reference implementation | LLM regenerates from §1 Solver and §2 Operating point |
| `reports/results.md` | Reconstruction results | **Generated by running the solver** — do not fabricate |
| `reports/reproduce.md` | Step-by-step verification recipe | LLM regenerates as a recipe matching what was actually run |
**Prompt for your LLM after editing this Markdown:**
> Read the attached Markdown. Regenerate the sibling `.json` so every field matches.
> Also regenerate `code/solver.*` and `reports/reproduce.md` per the schema.
> Output each file in its own fenced code block tagged with the filename.
> Do NOT fabricate `reports/results.md` — it must come from actually running the solver.
