Design justification file

A standalone Design Justification File is not applicable to this project. For eo-data-embedding — a single-developer, non-flight ground software project — the design rationale is folded directly into the SDD (§ Key design decisions: frozen encoder, exact FAISS IndexFlatIP, held-out threshold methodology) and into the V&V report, with requirements-to-design traceability carried in the traceability matrix and COTS reuse justified in the Software Reuse File (SRF). A separate DJF is therefore tailored out (see SDP §3, DJF row); this page is retained only as a pointer to those artefacts.
