An MnaRecording is the second tier of the subject → session → recording → file hierarchy used by MNA, and corresponds to a single "press record / stop record" interval in the acquisition software: one FIFF raw file plus its derived artefacts (events, evoked, behavioural log, …). Modelling this boundary explicitly avoids the legacy .ds / .fif sprawl where the only grouping was a shared filename prefix.

The id field is opaque to MNALIB but is conventionally the recording's base name (e.g. run-01_meg) so the user-facing GUI can render meaningful tree labels. files is an ordered MnaFileRef list whose first MnaFileRole::Raw entry is treated as the canonical recording; everything else is derived data. extras keeps tool-specific metadata (acquisition notes, BIDS sidecars) attached without forcing schema changes.
