Legal-hold boundary

Make legal-hold boundary an inspectable system decision with a named owner, defined trigger and retrievable evidence.

RECORD ANATOMY

What this control needs to be reviewable.

Objective
Make legal-hold boundary 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.

  1. 01

    Scope the decision: define the decision, owner, trigger, evidence and review path before implementation.

  2. 02

    Record the approved design and its source-status verification boundary.

  3. 03

    Connect implementation events to evidence that a reviewer can retrieve without broad production access.

EVIDENCE ARTEFACTS

  • Versioned decision record
  • Named ownership and approval
  • Implementation or test evidence

CONTROL TEST

  1. Select a recent, in-scope sample for legal-hold boundary and record why it was chosen.
  2. Trace the sample from its trigger and owner through the implemented system to the retained evidence.
  3. Record exceptions, confidence and remediation without converting an unknown into a pass.

ANTI-PATTERNS

Completion labels can hide an evidence gap.

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.
