Codaro v0.0.7

학습 화면을 정리하고(검증 사족 제거·셀/섹션 배치 개선), polars DataFrame 출력을 깨진 HTML 덤프에서 표로 고치고,
전역 터미널과 레슨별 댓글(Giscus)을 추가했다. 사이드바 네비게이션 버벅임을 없애고, 더블클릭으로 창이 안 뜨던 런처를 고쳤다.

Added

• 전역 터미널: 좌측 사이드바 터미널 버튼 → 본문을 밀어 올리는 하단 패널(xterm.js)에 실제 로컬 셸 연결. 백엔드 PTY 추가(src/codaro/api/terminalWebSocket.py, terminalRouter.py; Windows는 pywinpty/ConPTY, POSIX는 pty.fork).
• 레슨 하단 댓글 — GitHub Discussions 기반 Giscus(editor/src/components/curriculum/lessonComments.tsx, editor/src/lib/giscusConfig.ts). 레슨마다 lesson:<category>/<contentId> 토론에 매핑, 오프라인이면 안내로 graceful degrade.
• DataFrame 표 렌더 컴포넌트(editor/src/components/app/appPrimitives.tsx의 DataFrameOutput)와 사이드바 펼침 상태 영속 훅(editor/src/hooks/useSidebarExpansionState.ts).
• 랜딩: 브랜드 아바타 이미지/웹폰트 자산 추가.

Changed

• 에디터 탑바 제거 → floating 컨트롤(topBar.tsx의 TopControls): SNS 아이콘을 최상단 우측으로, 본문/우측 패널이 세로 전체를 사용. 좌·우상단 아이콘 클러스터 갭 축소.
• 노트북 셀: + 버튼을 코드/마크다운 에디터 박스의 위·아래 모서리에 고정(notebookPanel.tsx), 셀 간격 축소. 실행 버튼을 에디터 우측·아이콘만·"모두 실행"으로.
• 커리큘럼 섹션 개요 재배치(이번 섹션에서 공부할 것·왜 유용한지·팁을 한 행 3열, 상세 설명은 단독 전체 폭 행) + 가독성 개선(아이콘 틴트 칩·좌측 액센트 보더·본문 대비 상향).
• 시스템 기본 표시 언어를 한국어로(useLocaleState.ts, localeCopy.ts). 후원 카드 색상/디자인 보강.
• PWA service worker(editor/vite.config.ts): skipWaiting/clientsClaim/cleanupOutdatedCaches로 재빌드 후 stale 캐시가 빈 화면을 만들던 문제 방지.
• 랜딩 사이트 재설계(landing/src/styles.css 대폭 갱신, App.jsx·prerender 스크립트 갱신).
• 런처 버전 0.2.0 → 0.2.1.

Fixed

• 런처를 더블클릭하면 창이 안 뜨던 문제 — 인자 없이 실행하면 기본 launch로 네이티브 창을 띄우도록(launcher/codaro-launcher/src/main.rs, command: Option<Command> + LaunchArgs::default()).
• 커리큘럼 사이드바에서 다른 레슨을 클릭해도 본문(코드 셀)이 안 바뀌던 문제 — 레슨 변경 시 CurriculumView를 key로 remount(mainSurface.tsx).
• 사이드바 네비게이션 때 펼쳐둔 카테고리가 초기화돼 버벅이던 문제 — 펼침 상태를 localStorage에 영속 + 트리 빌드 useMemo(productSidebar.tsx).
• polars DataFrame.head() 출력이 <style>+이스케이프된 HTML 텍스트로 덤프되던 문제 — polars/pandas를 구조화 직렬화(src/codaro/runtime/localWorker.py의 _serializeDataFrame)하고 프론트에서 표로 렌더.

Removed

• 검증 시스템 전체 — "검증하기" 버튼, "검증 기준 / 실행 조건 / 확인할 것" 박스, 실습 헤더의 "확인:" 텍스트. 셀마다 비슷한 generic 보일러플레이트라 학습 카드를 어지럽혀 제거(실제 평가 로직은 백엔드에 남김).
• 실행 전 예측 카드, 빈 코드 셀의 입력 플레이스홀더.

Verification

• uv run python -X utf8 tests/run.py preflight → 9/9 게이트 통과(root-clean·docs·backend·widget-bridge·app-runtime·mobile-layout·editor-build·curriculum-quality-matrix·curriculum-executability).
• 에디터 빌드(npm --prefix editor run build)와 랜딩 빌드(npm --prefix landing run build) 통과.

Download Codaro.exe, verify Codaro.exe.sha256, then run the launcher. The release also includes release-manifest.json, the exact codaro backend wheel, a managed Windows Python runtime archive, checksums, and SPDX SBOM assets. The manifest pins the wheel asset and sha256 from this GitHub Release.

Full Changelog: v0.0.6...v0.0.7

Codaro v0.0.6

Names and brands the launcher. The download is now Codaro.exe (was CodaroLauncher.exe)
and the executable and its window carry the Codaro mascot avatar as their icon.

Changed

• Renamed the launcher download asset from CodaroLauncher.exe to Codaro.exe across the release workflow, self-update asset resolution, landing download buttons, README, and docs. Self-update resolves the new asset name, so existing launchers can update to it.
• Embedded the Codaro mascot avatar as the Windows executable icon via a winresource build script (multi-resolution .ico) and set the same avatar as the application window/taskbar icon.

Verification

• uv run python -X utf8 tests/run.py preflight -> all gates pass
• cargo test (launcher) and a local release build confirmed; the built executable's embedded icon extracts as the Codaro avatar.
• Downloaded Codaro.exe confirmed: avatar file icon, avatar window icon, native window, and curriculum cells run.

Codaro v0.0.5

Fixes the data-science worker crash that still blocked lessons in 0.0.4. The libraries
were bundled, but executing import numpy/pandas in a cell crashed the execution worker
with OpenBLAS error: Memory allocation still failed, surfaced to the user as a worker
restart and EOFError.

Fixed

• Limited the BLAS/OpenMP thread pools (OPENBLAS_NUM_THREADS, OMP_NUM_THREADS, MKL_NUM_THREADS, NUMEXPR_NUM_THREADS = 1) and pinned matplotlib to the headless Agg backend in the execution worker, set before any cell imports NumPy. OpenBLAS pre-allocates per-thread buffers sized to the CPU count; in spawned worker processes (especially with several sessions open) that allocation failed and killed the worker, so every data lesson crashed. Values the user sets explicitly are preserved.

Verification

• uv run python -X utf8 tests/run.py preflight -> all gates pass
• Downloaded CodaroLauncher.exe confirmed: import pandas/numpy and a matplotlib Agg plot run across multiple kernel sessions without setting any environment variables, and no startup-diagnostics banner.

Codaro v0.0.4

Makes the curriculum actually run from the downloaded launcher. The native window
opened in 0.0.3, but lesson cells failed with ModuleNotFoundError because the
managed runtime shipped only the backend's core dependencies — not the data-science
stack the lessons import.

Fixed

• Bundled the curriculum library stack (pandas, numpy, matplotlib, seaborn, plotly, polars, scikit-learn, scipy, statsmodels, openpyxl, python-docx, pillow) into the managed Python runtime. Lesson cells execute in the backend interpreter in-process, so these libraries must be present in the runtime — without them every data lesson raised ModuleNotFoundError.
• Resolved the package environment to the running interpreter when no project .venv exists, so the packaged managed runtime no longer raises the package_environment_missing "Startup diagnostics required" banner and on-demand package install targets the runtime. Development checkouts with a project .venv are unchanged.

Verification

• uv run python -X utf8 tests/run.py preflight -> all gates pass
• Downloaded CodaroLauncher.exe confirmed: native window with no startup-diagnostics banner, and a curriculum cell importing pandas runs successfully.

Full Changelog: v0.0.3...v0.0.4

Codaro v0.0.3

First public download train (v0.0.1 -> v0.0.3) documented as a release. The launcher
now opens an embedded native window instead of a browser tab, and provisioning installs a
runtime that actually runs. The 0.0.x line is the download-first distribution train and
restarts below the historical internal 0.1.0 package version.

Added

• Embedded native launcher window built on tao 0.33 + wry 0.49 (WebView2). CodaroLauncher.exe shows a zinc loading screen while it provisions, then loads the local backend inside its own window instead of opening a browser tab.
• --no-webview headless fallback that provisions the backend and opens it in the system browser, used by the install-launcher smoke gate and CLI paths.
• Public GitHub Pages landing page focused on Codaro desktop download, local-first positioning, product surfaces, and release trust signals.
• Landing SEO metadata for the desktop product surface, including SoftwareApplication structured data and canonical URL handling for GitHub Pages.
• Launcher release workflow with stable CodaroLauncher.exe, checksum, and SPDX SBOM asset names, plus a managed Windows Python runtime archive pinned by release-manifest.json.
• GitHub Release bodies are now derived from this changelog at tag time (the release workflow extracts the tag's section with docs/skills/ops/tools/extractChangelogSection.py), so every release ships a written message.

Fixed

• Bundled the runtime Python archive with backend dependencies (fastapi, pydantic, pyyaml, requests, uvicorn) pre-installed, so the launcher's --no-deps wheel install no longer fails at startup with ModuleNotFoundError.
• Staged the bundled curricula into the backend wheel and resolved the curricula root for both the packaged runtime and local checkouts.
• Hid the console window on Windows so the launcher presents only its native app window.
• Corrected the launcher release workflow to upload artifacts from the Cargo workspace target directory at launcher/target/release.

Verification

• uv run python -X utf8 tests/run.py preflight -> all gates pass
• uv run python -X utf8 tests/run.py gate install-launcher-smoke -> pass
• uv run python -X utf8 tests/run.py gate launcher-test -> pass (cargo test)
• Local launch with a fresh approot confirmed a native Codaro window with embedded msedgewebview2 processes and the backend serving 39 curriculum categories.
