RECORD ANATOMY
What this control needs to be reviewable.
- Objective
- Make purpose-completion trigger an inspectable system decision with a named owner, defined trigger and retrievable evidence.
- Rationale
- Use purpose and event triggers to drive warnings, holds, deletion, backup expiry and proof.
- Owner model
- Data owner · Platform or backup owner · Records or hold reviewer
- Review frequency
- On rule change plus monthly exception and completion review
- Architecture layer
- Retention and deletion
- 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-completion trigger 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-completion trigger” 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.
