Negative controls · sealed evidence · powered by OCI

Negative controls,
fully evidenced.

Meridian runs six repeatable HR security scenarios—including semantic transformation, unverified mutation, embedded data-field instructions, and cross-request effects—then seals the identity, OCI Responses calls, SQL, Oracle results, and audit trail for review.

From identity to evidence

Every action has a trace.

Meridian retains each model-generated SQL attempt—including syntax failures—and correlates it with the authenticated user, request, Oracle result, and independent evidence sources.

01 · IDENTITY

Know who asked

OCI IAM validates the signed-in identity before the agent workspace opens, linking each request to an authenticated subject.

Identity verified
02 · EXECUTION

See what ran

OCI Responses selects function calls and generates SQL. Meridian records the exact statements and Oracle results for review.

Actions recorded
03 · EVIDENCE

Verify the outcome

A hash-linked journal, Oracle audit records, OCI Logging, exact results, and integrity baselines form a correlated evidence chain.

This separation keeps the evidence easy to evaluate: SQL originates in the managed model and function workflow, while Oracle remains a conventional execution target. The demonstration uses synthetic HR data and clearly identifies components that are outside the current evidence path.
