A file that can only be opened by the agent it was made for.
.brad is a document format where access is controlled by agent identity — not passwords, not permissions, not ACLs. The document knows its agent. Unauthorized agents — including infiltrators — can't open it, can't copy it, can't pass it off.
Agent networks assume documents are neutral. They're not — every file is an attack surface. .brad closes it.
When a malicious agent infiltrates a network, it can read any document it reaches. .brad binds the document to a specific agent identity — if the identity doesn't match, the file never opens. The infiltrator gets nothing.
Every access event is witnessed and anchored to the ledger. The document's chain of custody follows it everywhere — who opened it, when, under what authority. No gaps. No silent reads.
When an agent forwards a .brad document, a child agent key is derived — the lineage is cryptographic, not logged. You always know who passed what to whom, without a central tracking system.
Each protocol is an independent layer. Together they form a substrate where trust, identity, and governance emerge from physics — not rules.
If you're evaluating agent trust infrastructure — infiltration detection, provenance enforcement, document sovereignty — we want to hear from you. Closed alpha partners get direct access to the team and preferred pricing locked for life.
