FileHeader — the Part 21 HEADER section, shared by reading and writing.
Every STEP file opens with three HEADER records. FILE_DESCRIPTION says
what the file contains; FILE_NAME records where it came from — file
name, timestamp, authors, organizations, the STEP processor, and the
originating CAD system; FILE_SCHEMA names the schema. FileHeader
models all three and lives on the StepModel: reading surfaces the
source file’s header as StepModel::header, and authoring fills it
through StepBuilder::header for the
written file.

Header - The Part 21 HEADER section (
FILE_DESCRIPTION+FILE_NAME+FILE_SCHEMA). Reading decodes it from the source file; the builder fills it from user input plus its automatic timestamp and preprocessor stamp. The default is the customary all-empty header.
