FathomDB is a rewrite-in-progress centered on the 0.6.0 design corpus.

Repository layout:

• docs/ contains public MkDocs source and client-facing technical positions.
• dev/ contains internal engineering material: requirements, architecture, ADRs, subsystem design, interface contracts, and planning notes.
• src/ contains implementation roots and unit-test-adjacent code.
• test/ contains cross-language, smoke, fixture, and performance assets that are not package-local unit tests.

Implementation roots:

• Rust workspace members live under src/rust/crates/
• Python package root lives under src/python/
• TypeScript package root lives under src/ts/

Start here:

• Public docs: docs/index.md
• Internal docs index: dev/README.md
• Workspace checks: scripts/check.sh

Common commands:

cargo check --workspace
pip install -e src/python/
cd src/ts && npm install
mkdocs build --strict
