Revises the Book 3 discovery mechanism, site geography, and Pip's
species while preserving Act 2-3 structural beats, the seal/lock
inversion, the WellsMoon callback, the Ch19 confrontation, and the
Ch21 elevation. Introduces the 20-year Pathfinder-survey backstory,
Devod's direct site connection at age ~35, the scout-death mechanism
that explains Ledger's 4-month delay, and Pip as a true dragon grown
from earth-magic-mutated lizards with growth gated by residue intake.
