+# Dev log — 2026-10-18
+
+## What I did
+- Task 0001 done (issues #1, #2): cargo skeleton with lib/bin split, one sanity test,
+  and `.gitea/workflows/ci.yaml` running fmt/clippy/test on push.
+- Learned `cargo init` vs `cargo new`; rewrote first commits into Conventional Commits
+  and pushed the branch.
+- First CI debugging: two red runs fixed by adding `dtolnay/rust-toolchain@stable`;
+  then a red run on `main` caused by a flaky toolchain download — a rerun went green.
+- Merged PR #13 into `main`; closed issues #1 and #2.
+
+## Frustrations
+- Reading English text (docs, CI logs) takes too much of the session — to discuss at retro.
+
+## English practice
+- *pipeline* — конвейер CI; *the pipeline runs fmt, clippy and test*.
+- *flaky* — нестабильный (то падает, то нет); *the runner's network is flaky*.
+- *rerun* — повторный запуск; *a rerun of the failed job went green*.
+
+## Next session
+- Install `bacon` (task 0002, drill D1) and verify the fast-feedback loop.
+- Drill D3: three deliberate compiler errors into the ErrorJournal.

 ## 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).

 ## Acceptance criteria

-- [ ] `cargo test` green with one sanity test
-- [ ] `.gitea/workflows/ci.yml`: `fmt --check` + `clippy -D warnings` + `test` on push

 ## 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).
