+## wrapper: Operational Constraints

+### Schema authority
+Primary: docs/wrapper-schema.md
+Supporting: ~/ontai/conductor/docs/conductor-schema.md (RunnerConfig contract)
+Supporting: ~/ontai/guardian/docs/guardian-schema.md (execution gatekeeper conditions)
+
+### Invariants
+CI-INV-001 -- Runtime delivers only pre-rendered Kubernetes manifests. No Helm or Kustomize at runtime. (root INV-014)
+CI-INV-002 -- ClusterPack, once registered, is never modified. Changes require a new PackBuild. Immutability is absolute.
+CI-INV-003 -- PackExecution is not submitted until all three execution gatekeeper conditions pass: PermissionSnapshot current, RBACProfile provisioned, ClusterPack not revoked.
+CI-INV-004 -- Leader election required.
+CI-INV-005 -- The agent bootstrap exception is the only context where pack application bypasses PackExecution. It is documented and finite.
+
+### Session protocol additions
+Step 4a -- Read wrapper-design.md in this repository.
+Step 4b -- Verify the pack-compile or pack-deploy capability is declared in RunnerConfig status before implementing any Job submission.
