This guide is for the engineering lead, platform owner or compliance owner who already ran our decision-class consolidation framework to merge two approval queues and froze both source queues as read-only archives rather than deleting them, and who then used our merger-validation framework to prove the merged ruleset safe and cut it over. Both guides stop at "keep the archives." This one answers what happens next: how long each archive and its ground-truth bank stay, and what has to be true before either is actually deleted. Our AI automation guide covers process governance more broadly, and the agentic AI automation service covers delivery.

Is "keep the archive forever" actually the safe default?
No, and treating it as free is the mistake this guide exists to correct. An indefinitely kept archive still costs storage and review time, and it carries a subtler risk: the longer it sits unused, the more its apparent usefulness as something to "check a disputed decision against" quietly erodes, because the production systems, data schemas and staff who understood the original ruleset's context keep moving on without it. Keeping an archive past the point it can still serve its purpose is not caution; it is an unexamined default standing in for an actual decision. The opposite mistake — deleting on a fixed calendar date regardless of what still depends on the archive — is equally unsafe. Neither "forever" nor "on a timer" is a policy; a policy names the conditions that make deletion safe for a specific archive, and checks all of them before anything is removed.
The three-condition deletion-trigger matrix
An archive is safe to delete only when all three conditions clear for its decision class. This reuses the same impact tiers our evaluation harness and merger-validation guide already use, rather than inventing a new scale.
| Impact tier of the archived decision class | What must clear before deletion | Why that tier needs it | Safe to delete when |
|---|---|---|---|
| Read-only or internal, no regulated decision | The shortest applicable retention clock, if any, and a short look-back window | Low risk, low dispute likelihood | The clock and window have both run out |
| Reversible write, regulated or customer-facing | The longest applicable retention clock and the full look-back window for every migrated case | Still reversible, but regulated or customer-facing data is involved | Every migrated case has aged out of both the clock and the window |
| Irreversible or external, with historical cases on both sides | The longest retention clock, the full look-back window, and a clear cutover-validation replay | An undone action; a disputed validation result here still blocks deletion | Clock, window and replay all clear, with zero open disagreement |
| Any tier, under active legal hold, audit or dispute | The hold itself, regardless of how long the other clocks have run | A hold overrides any clock already elapsed | Never while the hold stays open |
A class that clears every column can be deleted on its own schedule; a class that does not stays archived even if every other class from the same merger is long gone. Deletion is a per-class decision, not a single date for the whole archive.
Building the retention-and-deletion check
-
Inventory the archive by the same decision-class tiers used to merge and validate it
Reuse the consolidation framework's class list rather than re-deriving a new one; an archive is a set of classes, not one undifferentiated blob to keep or delete at once.
-
Set the regulatory retention clock per class, from the audit-trail guide's own rule
The audit-trail guide's retention-by-risk-tier rule already names the longest applicable obligation for a decision class's data; apply that same clock to the archived source ruleset and its ground-truth bank, not a separate number invented for the archive.
-
Set the look-back dispute window per class, from the rollback and sunset guides' discipline
Those guides define how long a past decision can still be reopened against the rule that produced it; the archive has to survive at least that long, because it is the only record of what that rule actually was at the time.
-
Check for an open validation-replay dependency before closing any class
The merger-validation guide's scenario-diff replay reads from both source archives; a class whose replay result is still disputed, or whose cutover gate has not cleared, keeps its archive regardless of how long the other two clocks have run.
-
Record the sign-off and the date for every class that clears all three conditions
, naming who approved the deletion, under the same named-ownership discipline this cluster's operating-model guide already assigns to a live decision class; our deletion evidence package guide defines exactly what that record must contain, sealed before deletion runs.
-
Delete per class, not per archive
Remove only the classes that cleared; leave the rest of the same source queue's archive in place until its own conditions clear, exactly as the matrix above states.
Deleting an entire source queue's archive because most of its classes have cleared, while one class is still inside its look-back window or under an open replay dispute, is the most common shortcut this checklist exists to prevent.
Where AI fits
Netbase works with the major commercial and open-source AI tools and models, chosen per project, and treats archive retention as part of the same operating discipline that governs a live agent's logs and rollback history, not a one-time cleanup task bolted on after a merger is forgotten.

Archive retention and deletion design for agent governance
Building the three-condition matrix and the per-class sign-off into a multi-queue agent program's operating model, alongside the enterprise AI agent platform for a shared runtime; not yet tied to a published case that names this exact step.
What delivery record exists, and what does not
What exists. Beyond 4over4 (whose Illustrator-to-SVG file conversion is automation, not AI), Netbase has delivered AI projects for clients that are not named, including document AI work whose rule-retirement discipline this guide's matrix extends (F072). Netbase follows its published security practices — role-based access control, secure code review, vulnerability scanning — the access-control discipline a documented deletion sign-off depends on (F021). Netbase holds ISO 27001 certification and a SOC 2 Type II attestation for its own operations (F022, F051, F052), and works with AI tools and models chosen per project (F070).
What does not exist. No published Netbase record names a retention duration, a storage-cost figure, or a count of archived rulesets deleted for a specific client. No record describes a dispute that reopened a decision after its source archive was deleted. The three-condition matrix is a reasoned structure built on this cluster's own prior guides and the cited data-retention and AI-governance sources, never a Netbase benchmark.
Alternatives: who decides when an archive can be deleted
| Approach | Strength | Weakness | Choose it when |
|---|---|---|---|
| Keep every archive indefinitely, by default | Simple; never risks deleting something still needed | Storage and review cost grow without bound; nobody revisits whether an old archive still serves any purpose | A very small number of mergers, or while the retention policy itself is still being designed |
| Delete on a fixed calendar date after cutover, regardless of tier | Predictable, easy to schedule | Ignores regulatory minimums and open disputes; the first disputed case after the deletion date has nothing left to check against | Never for a regulated or irreversible-tier class; only ever defensible for the lowest-risk internal tier |
| Per-class three-condition matrix, owned in-house | Matches deletion timing to actual risk and obligation; full control by people who know both source queues | Needs the regulatory clock, the look-back window and the validation status tracked per class, not just per archive | A named owner and both source queues' history are already assembled from the consolidation and validation steps |
| Bring in a delivery partner to design and run the retention review | Solves the case where no internal owner has capacity to track every class's clock; a fixed-price or milestone-based engagement can scope just the review (F067, F018) | Adds a hand-off step to brief an outside reviewer on both queues' history and obligations | Nobody internal owns this today, or several mergers need one consistent retention policy |
Most Netbase projects run on fixed-price contracts agreed after discovery, with milestone-based and retainer terms also offered where they fit better (F067, F018); a retention-policy design engagement is scoped and priced the same way.
Limits of this guide
- This is an engineering and governance framework, not legal or regulatory advice: confirm which retention obligations actually apply to a specific decision class's data, sector and jurisdiction before setting its clock.
- No figure in this guide is a Netbase benchmark: no retention duration, storage cost or deletion count is published as a Netbase result, because none is registered as a Netbase fact.
- The matrix assumes the consolidation and validation steps already tagged every migrated case with its source queue and class; an archive with no such tagging has to be reconstructed before any deletion decision can be made safely.

Frequently asked questions
No. Each decision class's archive stays only until its regulatory retention clock has run out, its look-back dispute window is closed, and no cutover-validation replay still depends on it; once all three conditions clear for a class, that class's archived record can be deleted.
Treating the whole archive as one unit instead of deciding per decision class, so a single still-open class, under a regulatory hold or an active dispute, either blocks deleting anything or gets deleted along with classes that were actually clear.
No. A clean cutover proves the merged ruleset behaves correctly going forward; it says nothing about whether a pre-merge decision from the archived rulesets is still inside its regulatory retention period or its look-back dispute window.
