+## Delivery doctrine
+
+Package delivery follows one source of truth:
+
+1. The Bzlmod module graph is the canonical (SSOT) delivery mechanism.
+   Consumers depend on `tummycrypt_scheduling_kit` through the
+   `tinyland-inc/bazel-registry` registry line already present in `.bazelrc`.
+2. GitHub Packages (`@jesssullivan/scheduling-kit`) is a derived package: the
+   out-of-ecosystem alternative route for npm-style consumers, built from the
+   same Bazel `//:pkg` output (`./bazel-bin/pkg`) that the module graph models.
+3. npmjs (`@tummycrypt/scheduling-kit`) is retired for first-party delivery.
+   It is frozen at `0.8.0`, and `npm_publish_mode: disabled` in the CI and
+   publish workflows is permanent policy, not a temporary outage.
