LunaNet Requirements Traceability Plan

Source basis:

• Tracks/LunaNet/requirements.pdf

Purpose

Map LunaNet FR/NFR requirements to modules, tests, evidence, and ownership so every mandatory criterion can be demonstrated with reproducible proof.

Requirement Families

• FR-1 Code generation (Gold, Weil primary, secondary, tertiary, tiered coherence)
• FR-2 Message encoding (BCH, LDPC, CRC, interleaving, frame assembly)
• FR-3 Signal generation (AFS-I/AFS-Q rates, BPSK mapping, I/Q formats)
• FR-4 Message decoding (sync detection, soft-decision BCH, LDPC BP, CRC, deinterleaving)
• FR-5 Message parsing (subframe extraction, WN/ITOW/TOI, transmission timing)
• FR-6 Validation/testing (vectors, BER, compliance)

Non-Functional Requirements

• NFR-1 Performance
  • Code generation < 1 sec per PRN
  • Frame encoding < 100 ms per frame
  • Frame decoding < 1 sec per frame
• NFR-2 Accuracy
  • Reference code exactness and sync reliability
• NFR-3 Testability
  • High coverage and reproducible vectors
• NFR-4 Usability
  • Clear docs and examples
• NFR-5 Maintainability
  • Modular architecture and clean interfaces

Traceability Method

1. Assign requirement IDs to implementation modules.
2. Attach unit and integration test IDs.
3. Define exact pass/fail threshold per requirement.
4. Store artifacts under predictable paths.
5. Gate completion on evidence review.

Why this method:

• LunaNet includes algorithm-heavy components where correctness is not visually obvious.
• Traceability avoids silent divergence from Annex/reference data.

6-Person Requirement Ownership

• Engineer A: FR interpretation and ambiguity disposition
• Engineer B: NFR thresholds and acceptance metric governance
• Engineer C: interoperability acceptance criteria alignment
• Developer A: FR-1/FR-2 implementation coverage
• Developer B: FR-3/FR-5 implementation coverage
• Developer C: FR-4/FR-6 and automation coverage

Evidence Contract (per requirement)

• Requirement ID
• Source section/table
• Module(s)
• Test case IDs
• Performance thresholds
• Evidence file path
• Reviewer sign-off

Exit Criteria

• 100% mandatory FRs mapped and test-backed
• NFR performance and reliability targets reproducibly measured
• Risk exceptions documented with mitigation and owner
