STO, SPT, BSEG-RBETR. Which table joins to which, on what key, at what grain. Every engineer works it out again from scratch, and every agent guesses at it fresh on each query. Nothing is written down, so nothing is reusable.
"Ask two engineers how to count active contracts.You'll get two queries and two numbers."
1 concept, 6 technical names
Step 1
Metagem compiles a contract per domain from your context graph: grains, join rules, definitions, and the traps that catch people out.
Step 2
One endpoint hands that contract to any engineer, pipeline or agent, so everyone works from the same locked description instead of re-deriving it.
Step 3
Compiling exposes what is missing. Absent foreign keys, ambiguous columns, undocumented abbreviations: each becomes a finding rather than a silent assumption.
Schema knowledge, written down once.
What one row represents, and how tables legitimately connect.
The gotchas your team learned the hard way, captured once.
Engineers, pipelines and agents read the same description.
Missing keys and ambiguous columns become findings you can act on.
Common questions about data contracts.
We compile one from a single domain and walk through what it exposes.
