+# Canonical OU Architecture
+
+The canonical OU tree implementation is organized around a narrow, flat row-major
+numerical core. Matrices in canonical hot paths should be represented as
+`double[]` with index `row * dimension + column`. Use `double[][]` or EJML
+objects only at legacy, BEAST, or external-library boundaries where conversion
+would cost more clarity or performance than it saves.
+
+## Module Boundaries
+
+- `dr.evomodel.treedatalikelihood.continuous.canonical.traversal`
+  owns tree state plus post-order and pre-order movement. It should not own
+  gradient target math, BEAST/CDI lifecycle, or OU backend specialization.
+- `dr.evomodel.treedatalikelihood.continuous.canonical.message`
+  owns canonical Gaussian states, branch transition factors, local adjoints, and
+  Gaussian message algebra. It should stay tree-topology agnostic.
+- `dr.evomodel.treedatalikelihood.continuous.canonical.gradient`
+  owns tree-level adjoint preparation and pullbacks to model gradient targets.
+  It should not know BEAST/CDI lifecycle details or specialized backend classes.
+- `dr.evomodel.treedatalikelihood.continuous.canonical.adapter`
+  owns BEAST/CDI lifecycle, tip synchronization, root-prior adapters, dirty state,
+  and cache diagnostics. It adapts external model objects into the canonical core.
+- `dr.evomodel.continuous.ou.canonical`
+  owns the OU kernel contracts and optional backend capability interfaces. It is
+  the narrow model/kernel surface consumed by canonical tree code.
+- `dr.evomodel.continuous.ou.orthogonalblockdiagonal`
+  owns the private specialized orthogonal-block backend: basis caching, prepared
+  branch data, transition/covariance assembly, and native gradient pullbacks.
+
+Boundary tests in `CanonicalPackageBoundaryTest` enforce the most important
+dependencies. When a new dependency violates those tests, prefer adding a small
+capability interface at the boundary over importing implementation packages
+directly.
+
+## Gradient Ownership
+
+Canonical OU tree gradients enter through
+`canonical.adapter.CanonicalOUGradientAdapter`, which delegates to
+`canonical.adapter.CanonicalOUTreeLikelihoodIntegrator`. The integrator owns
+gradient accumulators, the cached joint-gradient values, and the reusable
+`canonical.gradient.BranchGradientInputs` prepared state.
+
+`BranchGradientInputs` is the single canonical tree-gradient preparation product:
+it carries branch-local `CanonicalLocalTransitionAdjoints`, effective branch
+lengths, prepared transition/basis handles from the transition cache, and the
+root pre/post-order states. Selection, diffusion, stationary-mean, branch-length,
+and root-mean gradients should consume this prepared state instead of preparing
+their own local branch adjoints.
+
+`BranchSpecificGradient` and `ContinuousTraitGradientForBranch` are legacy
+branch-gradient machinery. They must not become dependencies of the canonical
+tree-gradient backend. Canonical diagnostics may compare against legacy or finite
+difference results, but those comparisons should live in tests or explicit debug
+helpers rather than normal analytic dispatch.
+
+Parallel canonical branch-gradient preparation and pullback use caller-owned
+`BranchGradientWorkspace` instances, one per task-pool worker plus a reduction
+workspace. Shared transition/basis data is owned by the transition cache; worker
+loops should only write to worker-local scratch or to child-indexed staging slots.
+
+## Orthogonal-Block Pullbacks
+
+The orthogonal-block backend is the only implementation package allowed to know
+about the specialized block structure. Canonical tree gradients interact with it
+through model capability interfaces and caller-owned workspaces. The hot path is:
+
+- `CanonicalSelectionGradientPullback` prepares tree-level branch adjoints.
+- `SpecializedCanonicalSelectionGradientPullback` accumulates into reusable
+  `SpecializedGradientWorkspace` buffers.
+- `SpecializedCanonicalSelectionParameterization` and
+  `CanonicalGradientPackingCapability` expose fill/accumulate APIs only.
+- `orthogonalblockdiagonal` owns prepared branch/basis caches and any private
+  EJML or block-specialized scratch.
+
+Orthogonal-block pullbacks should be allocation-free after construction:
+rotation, compressed-block, native-block, diffusion, and mean gradients all use
+flat row-major `double[]` buffers supplied by the caller or by an explicit
+workspace. Do not introduce `double[][]` into canonical gradient internals, and
+do not add return-array pullback APIs to the canonical tree-gradient path.
