Let agents read broadly
Use external material for the current task without silently turning it into permanent instructions.
GRIFF Agent State Integrity
Your agents will remember something. Decide what earns the right.
GRIFF controls the moment an observation becomes memory. It checks the evidence, the source, the writer, and the policy before anything becomes durable—and checks it again before a future agent relies on it.
Part of GRIFFai Agent OS—the operating system for accountable AI work. Connect through the open MCP boundary or your application API; keep one evidence policy across agent runtimes.

The plain-English version
Reading something is not permission to remember it.
An agent can legitimately read a webpage, email, document, or another agent’s message. That does not mean the source should be allowed to change how the agent behaves tomorrow.
GRIFF creates a security checkpoint between what the agent observes and what the system will later trust.
Gate the state transition
Apply evidence, trust, authority, persistence, and confirmation rules before a durable write.
Keep the receipt
Trace each admitted or blocked memory to the inputs and policy decision that produced it.
Five separate questions
A real source can still be the wrong authority.
Provenance tells you where something came from. State integrity decides whether that origin is allowed to create this kind of future-authoritative state.
Does the evidence exist?
A reference must resolve to a real record before it can support a lasting memory.
Does it support the claim?
A real source is not enough. The cited evidence must actually ground what the agent wants to store.
May this source create this kind of state?
A webpage may inform a summary without gaining authority to install future instructions.
May this writer make the transition?
Tool access is not permission. The authenticated agent or person needs the right state-writing scope.
Is it safe to use now?
Every later read rechecks lineage, revocation, expiry, scope, and the purpose of the current task.
Write gate + read gate
Safe when stored. Safe when used.
A memory that was acceptable months ago may be expired, revoked, superseded, or wrong for today’s task. GRIFF checks both sides of the lifecycle.
Write-time integrity
Evidence existence, claim grounding, source trust, writer authority, confirmation, destination, expiry, and a durable hash-chain receipt.
Read-time admissibility
Receipt verification, active status, freshness, scope, purpose, revocation, supersession, and downstream-use recording.
Portable evidence
A memory receipt that survives the session.
The originating session is part of the lineage, not the only place it exists. Every durable object carries enough identity and policy context to be verified later.

THE STATE BOUNDARY
Control what agents remember. Prove why they act.
Start with a protected memory workflow, test your real attack cases, and keep the same integrity policy as you add agents, models, and deployment boundaries.
