Words made simple

A few useful meanings before you read the explanation.

Checkpoint
A saved snapshot of workflow progress that can help it continue later.
Authorization
Checking what that identity is allowed to read or do. Being logged in does not grant access to every record.
Tenant
A customer or organization whose data must stay separate from other customers in a shared application.

Beginner — Context versus memory?

  • Context is the information a model sees in the current call.
  • Memory is stored application data that may be selected for later context.
  • Persisting something does not make it accurate, current, relevant, or authorized for every task.

Intermediate — Checkpoints versus long-term memory?

  • Checkpoints recover execution progress; long-term memory stores selected preferences or verified past events.
  • I keep both separate from authoritative policy and claim records because their purposes and retention differ.

Senior — How do you prevent memory poisoning?

  • I define which sources may create memory, require provenance and verification for important facts, scope it by tenant/user, and provide expiry and correction/deletion.
  • Retrieved memory remains lower authority than fresh canonical business data.

Scenario — The assistant remembers a policy that has expired. What changes?

  • It must resolve current policy applicability through the business service.
  • Historical memory may explain past conversation but cannot decide the active version.
  • I invalidate dependent caches and test stale-memory conflicts explicitly.
