Registry
The ECM accounting role a thing plays: how it moves energy, exchanges phase, and stores or propagates memory.
What the term means
Registry is ECM bookkeeping. The book says a registry is the role a thing plays in the accounting system, especially how it moves energy, exchanges phase, and stores or propagates memory.
The goal is registry, not labels. Two objects can look different in one chapter and similar in another if their registry in the conservation ledger is comparable.
How it relates to the ECM
ECM uses registry to avoid double counting. A field, particle, lane, memory state, or cosmic structure may need to be read by its role in coherence rather than by its surface name.
Registry is also what lets L-Domain and R-Domain be compared as inverse presentations of the same scalar scaffold.
Why it is important to understand
This term matters because it tells readers how to read unfamiliar vocabulary. ECM names are supposed to keep roles consistent across topics.
Without registry, readers are left with labels but not roles. Registry turns each term into a working map of conservation behavior.
Book context
Book anchors: Chapter 1, page 29 defines registry/bookkeeping as the role a thing plays in moving energy, exchanging phase, and storing or propagating memory.
Read this as ECM vocabulary: it defines how the book uses the term inside its own conservation-first model. The term can overlap with standard physics or mathematics, but this page is explaining the ECM role first so readers do not lose the model-specific meaning.
