HALLUCINATED APIs — DO NOT USE

These APIs DO NOT EXIST. LLMs frequently hallucinate them.

// WRONG — these table access patterns do not exist
ctx.db.tableName                    // Wrong casing — use ctx.Db
ctx.Db.tableName                    // Wrong casing — accessor must match exactly
ctx.Db.TableName.Get(id)            // Use Find, not Get
ctx.Db.TableName.FindById(id)       // Use index accessor: ctx.Db.TableName.Id.Find(id)
ctx.Db.table.field_name.Find(x)     // Wrong! Use PascalCase: ctx.Db.Table.FieldName.Find(x)
Optional<string> field;             // Use C# nullable: string? field
