Make execution earn its authority.
SHAETHON AI designs deterministic security boundaries that govern generation payloads before they reach downstream compute, execution engines, or data stores.
Request Authority Path
Simulate incoming generation payloads to see how the decision gate evaluates identity, permits, and downstream execution boundaries.
Generates payload
Request intake
Verifies identity
Evaluates rules
Verifies Permit
Downstream Compute
{ "permit_id": "tether_pr_9823f0a1c2", "issuer": "SHAETHON-DECISION-GATE-01", "subject": "client_app_sub_881", "decision": "ALLOW", "target_scope": "llm:execution_sandbox", "replay_nonce": "9a0f7c22e4d01a89", "expires_at": 1774980200, "signature": "Ed25519:0x88f2a9...c4e10b" } Decide first.
Execute second.
Traditional architectures execute operations based on broad upstream permissions. SHAETHON AI introduces Tether: a fine-grained decision boundary positioned directly at the API gateway.
Before any payload reaches the execution engine, Tether generates cryptographically verifiable permits that declare strict limits on compute scope, memory access, and downstream network egress.
Execution boundaries reject any request lacking a fresh, valid Decision Gate permit.
Upstream Control
Situated directly at the API gateway to evaluate requests before allocation of compute resources or database handles.
Deterministic Gates
Evaluates structured outcomes (ALLOW, DENY, ESCALATE) before the generation payload executes or reaches target systems.
Cryptographic Tokens
Tether-issued, cryptographically signed permits with single-use replay protection prevent token reuse across sessions.
Isolated Verification
Separate execution boundaries verify signatures independently without storing centralized state or session keys.
Seven rules.
One path to execution.
Click any principle to view detailed architectural specifications, permit verification schemas, and sample code implementations.
Single Authority
Only the Decision Gate can authorize execution. No intermediate microservice or agent can grant execution permits independently.
No External Auth
Never accept authorization tokens directly from untrusted external clients. External identity only unlocks gateway intake.
Subordinate Auth
Client authentication grants gateway access, not execution authority. Authentication and authorization remain explicitly decoupled.
Enforce Only
The execution boundary verifies cryptographically signed permits; it possesses no logic or capability to grant permissions.
Replay Protection
All executable permits are single-use tokens verified using cryptographic nonces and short-lived expiration windows.
Audit Everything
All evaluation decisions and boundary verifications are committed directly to a cryptographic, hash-linked audit ledger.
No Alternate Paths
Exactly one path leads to authorized execution. Backdoor administrative bypasses, legacy session hooks, and emergency debug overrides are strictly eliminated from the network topology.
