+## 0.13.0 — 2026-07-11
+
+The alias-promotion minor. The 12 template alias sets proven by
+attune-rag's alias-expansion-sweep move from attune-rag's
+`aliases_override.json` (always a temporary home) into template
+frontmatter, their long-term home — so the aliases ship with the
+templates themselves.
+
+### Added
+
+- **182 retrieval aliases across 12 templates** promoted into
+  frontmatter (#9, #24). Purely additive: existing aliases preserved
+  verbatim; 221 distinct aliases corpus-wide, verified globally
+  unique, every promoted alias clears the retriever's 2-stemmed-token
+  minimum. Fixture benchmark: overall P@1 73.4% (gate ≥73%), R@3
+  83.2%; the small P@1 shift vs 0.12.0 is the retriever's 500-char
+  content preview now seeing larger frontmatter — root-cause fix
+  tracked in attune-rag (strip frontmatter from the preview,
+  measured +1.4pp). attune-rag retires the override entries and bumps
+  its pin to `>=0.13.0,<0.14` in the companion PR that closes #9.
