StrataDeclarative, versioned data pipelines

Compiles to SQL — DuckDB/Postgres/BigQuery/Snowflake. Lineage + contracts as types, immutable snapshots, agent-safe.

🧬

Declarative by construction

Models are pure Table→Table functions. The compiler chooses materialization, not the author. No Jinja.

🔒

Schemas, enums, nonnull/unique/protected checked at author/plan/runtime (3-phase pins E070) before any warehouse write.

🧭

Every output column knows its origin. strata lineage-diff gives blast radius in one line (E030).

🧊

Each run publishes a new layer. Rollback = repoint, never mutate. Content-addressed snapshots + replay.

🤖

Small grammar (~250 lines), no implicit coercions, GBNF-constrained decoding. AGENTS.md generated by compiler.

📦

pip install strata-lang or standalone 34M (PyInstaller) or Docker ghcr.io/tzinny-dev/strata — same CLI everywhere.
