Strata is an interactive simulator of how tiered data retention works. It treats memory like layers of bedrock — items settle through tiers as they age, with safety nets along the way.
Tiers (firewalled)
- Active — working set, read/write open to producers.
- Locked worker bin — quarantine, read-only to a sandboxed worker.
- Delete-bin — isolated and reversible until Z elapses.
- Purged — terminal, no recovery.
How aging actually starts
The clock for an item only starts ticking when its ref-count drops to zero. While any container references it, it lives in Active indefinitely. Drop the last reference and it begins the slide through X, Y, Z.
Legal-hold guard
A legal-hold or a container's retention-floor freezes aging at the current tier. Held items never advance — and any policy that tries to purge a held item is rejected by the deploy gate.
Reversibility
Items in Locked or Delete-bin can be restored back to Active. Once purged, gone forever.
Sandbox soak-test
Project the next N hours of aging in a sandboxed clone. The verdict — GO, REVIEW, NO-GO — is the gate before any policy change is committed.
