Purpose-owner assignment
Make purpose-owner assignment an inspectable system decision with a named owner, defined trigger and retrievable evidence.

RECORD ANATOMY
What this control needs to be reviewable.
- Objective
- Make purpose-owner assignment an inspectable system decision with a named owner, defined trigger and retrievable evidence.
- Rationale
- Make systems, data categories, purposes, owners and processors visible before deciding what should change.
- Owner model
- Processing inventory owner · System owner · Independent reviewer
- Review frequency
- Quarterly and on material system or purpose change
- Architecture layer
- Discovery and ownership
- Version
- 1.0 · 2026-08-30
IMPLEMENTATION SEQUENCE
Move from scope to retrievable evidence.
- 01
Scope the decision: define the decision, owner, trigger, evidence and review path before implementation.
- 02
Record the approved design and its source-status verification boundary.
- 03
Connect implementation events to evidence that a reviewer can retrieve without broad production access.
CONTROL TEST
- Select a recent, in-scope sample for purpose-owner assignment and record why it was chosen.
- Trace the sample from its trigger and owner through the implemented system to the retained evidence.
- Record exceptions, confidence and remediation without converting an unknown into a pass.
ANTI-PATTERNS
Completion labels can hide an evidence gap.
- Treating “purpose-owner assignment” as a policy sentence without an operating owner
- Marking the control complete from self-attestation alone
- Hiding missing, stale or inaccessible evidence behind a pass label
ARCHITECTURE → EVIDENCE DECISION JOURNEY
Follow the dependency, then inspect the proof.
Each connection uses existing catalogue records. Source IDs remain verification pointers—not provision mappings.

CHANGE LOG
Version 1.3 — Architecture-to-evidence journey and non-personal review-route relationship added; verification-pointer boundary retained.
Version 1.2 — Official-source status rechecked; command-centre indexing and the non-mapping boundary retained.
Version 1.1 — Engineering fields, source verification pointers and acceptance evidence reviewed.
Version 1.0 — Stable catalogue ID, objective, evidence model, test sequence and verification boundary established.
