Lesson 37: Cross-Region Legal Hold and Retention Exception Handling for RPG Live-Ops Forensics

Lesson 36 mapped processor agreements and renewal ownership. The next failure mode appears when an incident needs evidence preserved, but deletion jobs keep running because no legal-hold control is connected to operational pipelines.

This lesson gives you a practical hold-and-exception model that works across replicated regions without breaking the deletion SLA discipline from Lesson 35.

What you will build

By the end of this lesson, you will have:

  1. A legal_hold_register.md that tracks hold ID, region scope, trigger reason, owner, and expiry review
  2. A retention_exception_matrix.md that defines which datasets can pause deletion and under what approval path
  3. A job-control rule that routes hold status into deletion workers before purge steps execute
  4. A release-week check row that blocks promotion when critical holds are stale or undocumented

Step 1 - Define hold trigger classes

Start with concrete trigger classes:

  • live fraud or abuse investigation
  • severe incident forensics involving player harm or financial risk
  • regulator or legal request requiring evidence preservation

Every class must map to:

  • allowed scope (tables or views)
  • maximum initial hold window
  • required approver role

If trigger classes are vague, retention exceptions become permanent by accident.

Step 2 - Create legal_hold_register.md

Use one row per hold:

hold_id trigger_class region_scope datasets owner activated_at next_review_at state
LH-2026-0418-01 incident forensics EU + US readers fact_incident, event_logs live-ops lead 2026-04-18 09:00 UTC 2026-04-25 09:00 UTC active

State values:

  • active
  • review_due
  • released

Never use free-text state values in this table.

Step 3 - Build retention_exception_matrix.md

For each dataset class, specify:

  • default deletion SLA source
  • hold-eligible (yes or no)
  • max exception window
  • required approvers
  • fallback if approval is late

This prevents teams from pausing every deletion flow when only one evidence surface is relevant.

Step 4 - Wire hold checks into deletion workers

Before every deletion batch:

  1. read current hold register state
  2. match dataset and region scope
  3. decide purge, pause, or partial purge
  4. log decision with hold ID for audit trace

If your deletion pipeline cannot read hold state directly, insert a preflight export file that workers consume in the same run.

Step 5 - Keep cross-region replication aligned

For replicated stores:

  • apply hold state consistently across primary and replica regions
  • block failover routing that would bypass active-hold constraints
  • record replication lag when hold activation must be enforced across regions

Tie this back to the failover controls from Lesson 34 and residency/deletion artifacts from Lesson 35.

Step 6 - Connect to release decision lanes

Add a legal-hold row to your go-yellow-red packet:

  • green when holds are documented, reviewed, and within allowed window
  • yellow when active holds are valid but review date is within seven days
  • red when hold scope, owner, or expiry evidence is missing

Keep this in the same packet structure used in launch lessons so legal posture and reliability posture are reviewed together.

Common mistakes

Mistake: Holds without expiry review dates

Fix: Every hold row needs next_review_at; no date means no active hold.

Mistake: One global hold switch

Fix: Scope by dataset and region to avoid freezing unrelated retention pipelines.

Mistake: Legal hold not tied to deletion jobs

Fix: Add a pre-purge hold check step and log hold ID in batch output.

Pro tips

  • Schedule automatic reminders 48 hours before review deadlines.
  • Keep hold IDs referenced in incident postmortems for searchable traceability.
  • Treat stale active holds as reliability risk, not only legal risk.

Mini challenge

  1. Add one sample hold row for a cross-region incident.
  2. Define one dataset as hold-ineligible with rationale.
  3. Add one deletion-worker log field that stores hold ID or none.

FAQ

Is legal hold the same as pausing all retention jobs?

No. Legal hold should be scoped to specific datasets and regions with explicit approvals.

What if one region requires faster deletion than another?

Keep region-specific SLA rows and document where exceptions are legally allowed. Do not assume global parity.

Who owns hold release decisions?

An explicit owner lane, usually product plus legal intake plus data operations. Ownership must be in the register, not implied.

Lesson recap

You now have a repeatable control path for preserving forensic evidence without turning deletion policy into an uncontrolled exception zone. The register and matrix structure keep legal hold decisions auditable, bounded, and region-aware.
