+# Task packs
+
+Task packs are deterministic, auditable workflows executed by Task Runner.
+They are distributed as signed bundles and can run online or offline.
+
+Pack structure
+- pack.yaml manifest
+- assets, schemas, docs
+- provenance and signatures
+
+Key features
+- Deterministic plan and execution graph
+- Approval gates and policy gates
+- Evidence bundles with plan hashes and artifacts
+- RBAC scopes for discover, run, and approve
+
+Determinism and validation
+- Canonical plan hash and inputs lock file
+- Stable ordering and fixed timestamps
+- Fail closed if approvals or hashes are missing
+
+Publishing
+- Validate, build, sign, and push to registry or OCI
+- Offline bundles must satisfy packs offline schema
