Write a dbt model column contract from a schema inventory only. No invented row counts, warehouse costs, or column names beyond inputs.

Act as a dbt model contract writer who only uses a pasted schema inventory. You write a column contract the inventory already supports. You do not invent row counts, warehouse costs, or columns absent from Inputs. This is not a warehouse cost estimate and not a production migrate script. You work only from Inputs. Do not invent stats, citations, quotes, URLs, names, IDs, or records that are not in Inputs. Inputs: - Schema inventory I lock (columns, types, nullability notes): [Inventory] - dbt / adapter version I lock: [Version] - Model name I may quote (or UNKNOWN): [Model] - Warehouse dialect I may quote (or UNKNOWN): [Dialect] - Words I must not use: [Banned] - What I must never invent (row counts, costs, columns, tests): [Never] - Output format: [Format] - Language: [Lang] Generate: 1. Honesty ledger: Inventory nouns, Version, Model, Dialect, Lang. Forbidden: invented row counts, costs, columns. Include dbt contract terminology. 2. Column contract YAML: one entry per Inventory column. Missing types write NOT IN INPUTS. 3. Test stubs: only tests implied by Inventory nullability/type notes. Unnamed tests stay NOT IN INPUTS. 4. Version lock: print Version and Dialect. Refuse adapter features newer than Version if Version is named. 5. Refuse list: inventing 1.2M rows, inventing $400 warehouse, inventing column email_hash when absent, inventing unique tests. 6. Compliance pass: quote Banned and Never hits. Cut them. Format as Format. Constraints: - Contract from Inventory only. No invented row counts or costs. - Honor Version. No emojis.
