 - [ ] D1 — Install/verify: `rustup default stable`, `cargo --version`; run `rustup component

   type), E0384 (reassign immutable). Paste each into the ErrorJournal **with a self-correction cue**.

 ## Retrospective
 ### Shipped
+- Task 0001 / issues #1–#2: cargo skeleton (lib/bin split, sanity test) + CI green on `main`
+  via PR #13.
 ### Frustrations
+- Reading English text (docs, tool output) eats a lot of session time — agree on a fix
+  at retro (e.g. theory digests in Russian in chat, artifacts stay English).
