Overview
Contexts are the trust boundary for agent reads.
Hidden session bindings prevent the model from choosing tenant or principal values.
Evidence-required capabilities record which rows, chunks, and memory facts were used.
Developer notes
- Bind tenant_id from SESSION and mark it HIDDEN.
- Keep user-provided values in INPUT bindings.
- Filter every SQL and hybrid source by hidden tenant context.
- Require evidence for customer-visible agent answers.
