 # Changelog
 
+## 3.0.1 — dimension terminology clarification
+
+- Clarified that every use of “dimension” in the ETQ-303 construction refers
+  to finite-dimensional algebraic vector spaces unless explicitly stated
+  otherwise; it does not refer to physical spacetime dimensions.
+- Added notation conventions for scalars in `C`, `dim(V)`, tensor products over
+  `C`, and operators on declared finite-dimensional spaces.
+- Added the explicit derivation
+  `dim(H_303) = dim(H_101) dim(C^3) = 101*3 = 303` and stated that 303 is both
+  the algebraic state-space dimension and the number of basis-indexed states.
+- Clarified that `E8` is represented in an 8-dimensional Euclidean root space,
+  `D4` has rank 4, ETQ-101 contains 101 selected basis states, and ETQ-303
+  contains 303 tensor states.
+- Added the canonical LaTeX source, rebuilt PDF, publication build instructions,
+  and regenerated publication-file checksums to the repository.
+- No mathematical behavior, state indexing, event generation, deterministic
+  output, protocol hash, test fixture, implementation identity, or scientific
+  claim was changed. The archived v3.0.0 release remains immutable.

+## Notation and Conventions
+
+Unless explicitly stated otherwise, scalars are in \(\mathbb C\), all vector
+spaces in the ETQ-303 construction are finite-dimensional, \(\dim(V)\) is
+algebraic vector-space dimension, and \(\otimes\) is the tensor product over
+\(\mathbb C\). Operators act on the finite-dimensional spaces declared by the
+construction.
+
+Throughout the ETQ-303 documentation, “dimension” means finite-dimensional
+vector-space dimension unless another mathematical meaning is explicitly
+declared. It never means physical spacetime dimension. The \(E_8\) root system
+is represented in an 8-dimensional Euclidean root space, while each \(D_4\)
+factor has rank 4. Those numbers describe algebraic root spaces, not spacetime.
+No physical interpretation follows from rank, dimension, state count, or
+tensor-product notation alone.
+
+The state-space construction is explicitly
+
+\[
+\mathcal H_{303}=\mathcal H_{101}\otimes\mathbb C^3,
+\]
+
+with
+
+\[
+\dim(\mathcal H_{303})
+=\dim(\mathcal H_{101})\dim(\mathbb C^3)
+=101\times3
+=303.

+
+Thus 303 is both the algebraic dimension of the finite event/state vector space
+and the number of basis-indexed states. The \(\mathbb C^3\) factor is the
+declared independent three-state, or qutrit-like, protocol factor; it introduces
+no additional physical ontology.

+- Clarified that `E8` is realized in an 8-dimensional Euclidean root space,
+  `D4` has algebraic rank 4, ETQ-101 contains 101 selected basis states, and
+  ETQ-303 contains 303 tensor states.
+- Added the canonical v3.0.1 LaTeX source, generated PDF, build instructions,

+
+## Change boundary
+
+No mathematical construction, equation of motion, operator, state ordering,
+event ordering, canonical JSON, schema, deterministic receiver, fixture,
+checksum, implementation identity, test behavior, or scientific claim was
+changed. The protocol's machine-readable identity remains v3.0.0.
