MnaSession sits between MnaSubject and MnaRecording in the MNA project tree and mirrors the BIDS ses-XX directory level. It captures the natural grouping that occurs when a subject visits the scanner more than once — e.g. baseline, follow-up, intervention — without forcing those repeats into separate subject entries that would break longitudinal analyses.

The structure is intentionally thin: an opaque id (typically ses-01, ses-pre, ses-post), an ordered list of MnaRecording instances, and an extras bag for session-level sidecar metadata (date, scanner head-coil swap, paradigm version) that should round-trip losslessly even when unknown to the current MNALIB build.
