 Content guidance: use what is well established about EPIC (motifs such as Warrior of the Mind, Open Arms, Just a Man/My Goodbye, Ruthlessness, Monster, Little Wolf, Love in Paradise/Penelope's theme, Thunder Bringer, character themes for Odysseus, Athena, Poseidon, Zeus, Penelope, Telemachus, Polyphemus, Circe, Hermes…). The `.lrc` files in `/home/user/epic-the-musical-content` may be *read* to check where phrases recur, but no lyric text may be written anywhere. Mark every uncertain value `// TODO(verify)`.
 
-- [ ] **Step 1: Write failing tests** in `tests/album.test.ts`: 9 sagas ordered troy…ithaca; `songs.length === 40`; tracks 1..40 contiguous; `songs.map(s=>s.title)` equals the pinned list; each saga's `sagaTrack` 1..n; every `motifIds`/part motif exists in `motifs` and every motif is used ≥2 songs; `storyTime.yearsAfterTroy` non-decreasing by track; landing mapping as pinned; `fanWorks` is `[]`; `prevNextWithMotif` on a motif's middle occurrence returns both neighbours; if `/home/user/epic-the-musical-content/Songs and Lyrics` exists, `scanLibrary` titles (normalised: lowercase, strip non-alphanumerics) equal the album titles in order.
