This export is generated from an immutable, append-only audit log. Every item and link in this package carries a chained content hash back to its creation. Signatures are bound to (a) the signer's authenticated identity at time of signing, (b) server-attested UTC timestamp, (c) the content hash of the signed artifact, and (d) a user-asserted meaning of signature. Regeneration of this package for the same baseline will always produce an identical content hash; any divergence indicates tampering or post-baseline change.

§3Forward Trace Matrix
Forward traceability establishes, for each source artifact, the set of downstream artifacts that realize, test, and verify it. The matrix below is organized into two sub-sections: user needs to system requirements (§3.1), and system requirements to software requirements, design, verification and validation (§3.2).
3.1 User Needs → System Requirements → Validation

§4Backward Trace Matrix
Backward traceability demonstrates that every test, verification, and validation activity is tied to at least one requirement. Any row lacking an upstream reference is a finding (see §5 Gap Analysis).

§6Per-Item Records
The following are the full controlled records for each item in the baseline: description, rationale, upstream & downstream trace, approval history, and change log. For brevity this mockup shows six representative records; the production export contains all items in the baseline.

§7Audit Log Excerpt
Append-only audit log, scoped to changes affecting items in this baseline between baseline creation and lock. Each row's hash is chained to the previous; tampering is detectable.

§8Approvals & Signatures
Part 11 electronic signatures bound to this baseline. Each signature is captured after successful re-authentication (password + TOTP) and is cryptographically linked to the signed artifact's content hash, the signer's identity, a server-attested timestamp, and a user-asserted meaning of signature.
