Pink

Requirement text

Detail data lineage and provenance controls across the delivery lifecycle, including automated capture, immutable trail and independent audit access.

Drafted answer

draft.v2 · Drafting Agent

ClaimEvery data movement across the delivery lifecycle is captured automatically at the platform layer, written to an immutable audit trail hashed on-write and made available to the buyer's internal audit function on read-only terms.

Evidence anchorAudit trail architecture reference EV-2026-0180 · ISO 27001 certification signed 22 Feb 2026 · Independent auditor attestation EV-2026-0182.

ConfidenceHigh. Automated capture is verifiable against the reference implementation; auditor attestation is signed.

Counter-viewA competitor whose lineage is captured manually or in application code will claim equivalent traceability; the response should emphasise platform-layer capture as the discriminator.

Discriminator injection

Layer 16

Against a competitor known to rely on application-layer lineage, sharpen to the lineage runs beneath the application layer, so no future application change can silently break the trail.
