MnaProject is the in-memory representation of one .mna (JSON) or .mnx (CBOR) file and the entry point for every other MNALIB type: it owns the MnaSubject list (subject → session → recording → file) plus the MnaNode pipeline that describes how derivatives are produced from raw inputs. Reading or writing a project is a single MnaIO call away — read and write are thin façades that dispatch on extension.

The container is intentionally declarative: it records what should be computed (operations, parameters, file references and hashes) rather than embedding executable code, so collaborators on different platforms can reproduce the analysis using their own MNE-CPP build. mnaVersion / CURRENT_SCHEMA_VERSION are bumped on breaking schema changes, while extras preserves forward-compatible additions so projects written by a newer version round-trip losslessly through an older one.
