[github-actions]

🤖 This PR is maintained by Autoloop. Each accepted iteration adds a commit to this branch.

Program Goal

Build tsb, a complete TypeScript port of pandas, one feature at a time. This is an open-ended program — it runs continuously, always adding the next piece of pandas functionality.

Current State

Best metric: pandas_features_ported = 1 (established in Iteration 1)

Iteration 1 Summary — Project Foundation

Established the complete project scaffold for the tsb TypeScript pandas port:

• package.json — tsb package, Bun runtime, Biome + fast-check devDeps
• tsconfig.json — strictest TypeScript settings (strict, noUncheckedIndexedAccess, exactOptionalPropertyTypes)
• biome.json — all linting rules enabled, zero-warning policy
• bunfig.toml — test coverage enabled
• src/index.ts — package entry point with planned export structure
• src/types.ts — core type foundation (Scalar, Label, Axis, DtypeName, etc.)
• tests/index.test.ts — hello-world smoke tests proving the pipeline works
• .github/workflows/ci.yml — CI with type-check, lint, test, build
• .github/workflows/pages.yml — GitHub Pages deployment pipeline
• playground/index.html — feature roadmap landing page
• AGENTS.md — project conventions for AI coding agents
