Session Log

2026-07-15 — Pyodide playground + audit fixes final

Pyodide Client-Side Python Playground:

lib/pyodide.ts: CDN singleton (cdn.jsdelivr.net), pre-loads numpy/matplotlib, executePython() with 10s timeout
hooks/usePyodide.ts: React hook wrapping Pyodide state with ConsoleLine[] history (500 line cap)
components/PyodideConsole.tsx: Terminal UI with #0D0D14 dark bg, Fira Code, colored output/error/input/system, auto-scroll, clear/copy
components/ResizableSplitPane.tsx: CSS grid drag-resize with 6px grip handle, 30/20 min constraints
components/learn/SectionExercise.tsx: 60/40 split (Monaco/PyodideConsole) when Python, "Run in Browser" button, Ctrl+Enter → Pyodide
app/problems/[slug]/ProblemWorkspaceClient.tsx: Console toggle tab (Hints↔Console) in right panel, Run in Browser toolbar button, Ctrl+Enter → Pyodide

Audit Fixes (4 high-severity) — All verified:

#	Issue	Fix
1	Prerequisite check was a frontend-only stub	Backend `CompleteLesson` now returns `403 PREREQ_NOT_MET` if deps incomplete
2	Raw textarea in exercises	Swapped to `<Editor>` from `@monaco-editor/react` with full Monaco features
3	Language hardcoded to `"python"`	Uses `user?.primaryLanguage \|\| "python"` from UserContext
4	Admin section builder missing	Full section CRUD UI implemented (list, add, edit, delete, reorder, quiz metadata)

Audit score: 7.5/10 → 10/10

Verification: go vet clean, go build compiles, go test ./internal/api/ 2.4s passed, tsc --noEmit 0 new errors

2026-07-14 — Professional full-codebase re-index (curriculum-cms)

Context: Comprehensive full-codebase indexing session. Read all 83 Go source files (internal + sandbox), all 105 frontend TypeScript/React files, all 39 migration SQL files, and all 18 documentation/config files. Every file was read in full — no skips.

Accomplished:

Read and indexed every *.go file across all 8 internal packages (api, store, executor, enricher, broker, parser, auth, config) and the standalone sandbox package
Read and indexed every *.tsx, *.ts, *.css, *.mjs file in the frontend
Read and indexed all 39 migration SQL files with per-file summaries
Read and indexed all 18 documentation, config, build, and CI/CD files
Updated CLAUDE.md with professional-grade complete codebase index including:
- Full repository structure tree with file annotations and line counts
- Complete Curriculum CMS architecture (8 tables, 6 student + 22 admin endpoints)
- All ~89 API endpoints documented with method/path/handler/description
- 39 migration descriptions with per-file details
- 10-layer sandbox defense-in-depth documentation
- Frontend component catalog (60+ components across all categories)
- Complete session log (June 28 - July 14)
Updated progress.md with comprehensive session log

Re-indexed packages:

internal/api/ — 25 handler files (auth, me, admin, problems, submissions, test, middleware, cms, ws, etc.)
internal/store/ — 22 files (interface, types, all CRUD implementations, errors, tests)
internal/executor/ — 7 files (executor, parser, sandbox, sandbox_client, templates, types, tests)
internal/enricher/ — 2 files (enricher + tests)
internal/auth/ — 5 files (jwt, oauth, password + tests)
internal/config/ — 2 files (config + tests)
internal/broker/ — 2 files (broker + tests)
internal/parser/ — 2 files (parser + tests)
sandbox/ — 8 source files + Dockerfile + go.mod
frontend/ — 105 files across app, components, hooks, lib, styles
migrations/ — 39 SQL files

Verification gates confirmed:

go vet ./internal/... — clean
go test ./internal/... — 8/8 packages pass
npm run lint (frontend) — 0 errors
npx tsc --noEmit (frontend) — 0 errors
