Language Playgrounds

Experimentation sandboxes for language and learning

Quick Start

git clone --recursive https://github.com/hyperpolymath/language-playgrounds.git
cd language-playgrounds

Note	The --recursive flag initializes all submodules. Submodules are pinned to specific commits for reproducibility.

State Files

This repository uses SCM state files for machine-readable project metadata:

• META.scm - Architectural decisions and development practices

• ECOSYSTEM.scm - Ecosystem positioning and relationships

• STATE.scm - Current project phase and milestones

• PLAYBOOK.scm - Operational procedures

• AGENTIC.scm - AI agent interaction patterns

• NEUROSYM.scm - Neurosymbolic integration config

Submodule Management

# Update all submodules to latest pinned commits
git submodule update --init --recursive

# Check submodule status
git submodule status

# Update submodule to new commit (maintainers only)
cd <submodule>
git checkout <new-commit>
cd ..
git add <submodule>
git commit -m "chore: update <submodule> to <version>"
