One family: **Nagell-Ljunggren equation** (`nagell-ljunggren`) — P2, open. - Standard form: `(x^n - 1)/(x - 1) = y^q` - Parent: `exponential-diophantine` Contents: the registry entry and its `docs/FAMILIES.md` section. References cited (the claim each one supports): - `Ljunggren1943` — the classical partial results - `BugeaudMignotte2002` — survey of the state of the art Independent of every other family PR: it needs only the registry backbone it is based on. Part of the series that splits #1 into reviewable pieces: 1. `01-bibliography` — packaging, docs, annotated bibliography 2. `02-parsing` — equation strings to a term model 3. `03-registry` — the YAML family registry (3 seed families) 4. `04-matchers` — shape recognizers 5. `05-classify` — the classification pipeline 6. `06-solvers` — solver framework, two seed solvers, and the CLI 7. `07..09-backbone` — the 23 parent families of the DAG, by depth 8. one PR per remaining family (38 of them, mutually independent) 9. `99-polish` — restore the full doctests and tighten the invariants
