Tool-result context binding

Stamps every tool result with the context that produced it, and verifies the stamp when the result is used — stale or wrong-task results are refused.

A result is only valid for the execution that produced it. At production time each tool result gets a signed binding stamp — task/execution, tool + argument hash, authorization scope, environment digest, causal sequence, TTL. At consumption time — cache hit, queue redelivery, checkpoint restore, cross-thread delivery — the stamp is verified and the host enforces the verdict: VALID / STALE / WRONG-TASK / DUPLICATE / OUT-OF-ORDER / INVALID, fail-closed for state-changing actions, with legitimate recovery by revalidation, never override.

Solo $9/mo · Fleet $19/mo · Verdict API $0.001 per check (x402).
