 A compiling `viexp` crate with lib/bin split, one passing test, and green Gitea Actions CI.
 
 ## Acceptance criteria
-- [ ] `cargo new`-style skeleton: `src/main.rs` + `src/lib.rs` (`main` calls `viexp::run()`)
-- [ ] `cargo test` green with one sanity test
-- [ ] `.gitea/workflows/ci.yml`: `fmt --check` + `clippy -D warnings` + `test` on push
-- [ ] First Conventional Commit pushed to `main`
+- [x] `cargo new`-style skeleton: `src/main.rs` + `src/lib.rs` (`main` calls `viexp::run()`)
+- [x] `cargo test` green with one sanity test
+- [x] `.gitea/workflows/ci.yaml`: `fmt --check` + `clippy -D warnings` + `test` on push
+  (with `dtolnay/rust-toolchain@stable`; file is `.yaml`, same thing)
+- [x] First Conventional Commit pushed to `main` (merged via PR #13; CI green, run #14)
 
 ## Notes
 Rust Book ch. 1–2; see [[sprints/sprint-00-setup|Sprint 0]] drill D2/D4.
 
 ## Log
 - 2026-10-17 — task created.
+- 2026-10-18 — done. Drills D2+D4: skeleton, sanity test, CI workflow. Two CI fix commits
+  (added the rust-toolchain step), merged to `main` via PR #13. Run #14 red → rerun green:
+  the runner's download from static.rust-lang.org timed out once (flaky network, not code).
