+ * Distils a decision journal into durable, repo-scoped memory lines for persistence to the
+ * cross-session L3 store. Pure transform (no I/O) so `core:journal` stays dependent only on
+ * `core:events`; the actual L3 upsert/retrieve lives in the wiring layer that owns the store.
+ *
+ * Each line is namespaced by [repoRoot] so retrieval can attribute a decision to its project.
