Counterfactual schema migration compiler
Compile the change before it compiles you.
Project warehouse DDL against the metadata graph.
Prove the release gate. Ship the migration pack.
Proposed DDL
SnowflakeJudge paths
3 fixtures
INPUT
DDL + metadata graph
OUTPUT
proof + DAG + PR pack
Release evidence
Awaiting compileGraph preview
Your migration evidence will appear here.
Compile once to project failure paths, prove the gate, route the execution DAG, and generate the PR pack.
Why this is different
Not another catalog chatbot.
01
Counterfactual graph
Projects the after-state and names each expected failure before DDL runs.
02
Policy as evidence
Stable rule IDs make every block auditable, reproducible, and CI-friendly.
03
Executable handoff
Compiles compatibility SQL, dbt contracts, parity tests, routing, and a hash-sealed capsule.
