                    Declared licenses and concluded licenses represent two different stages in the
                    licensing process within software development. Declared licenses refer to the
                    initial intention of the software authors regarding the licensing terms under
                    which their code is released. On the other hand, concluded licenses are the
                    result of a comprehensive analysis of the project's codebase to identify and
                    confirm the actual licenses of the components used, which may differ from the
                    initially declared licenses. While declared licenses provide an upfront indication
                    of the licensing intentions, concluded licenses offer a more thorough understanding
                    of the actual licensing within a project, facilitating proper compliance and risk
                    management. Observed licenses are defined in `evidence.licenses`. Observed licenses
                    form the evidence necessary to substantiate a concluded license.

As function calls are made, frames are pushed onto the stack, forming an array-like structure that orchestrates the flow of program execution and manages the sequence of function invocations.

                Defines a syntax for representing two character language code (ISO-639) followed by an optional two
                character country code. The language code must be lower case. If the country code is specified, the
                country code must be upper case. The language code and country code must be separated by a minus sign.

                        of 'major', 'minor', 'patch', 'pre-release', or 'internal'. Representing all possible software
                        release types is not practical, so standardizing on the recommended values, whenever possible,
                        is strongly encouraged.
                        * major = A major release may contain significant changes or may introduce breaking changes.
                        * minor = A minor release, also known as an update, may contain a smaller number of changes than major releases.
                        * patch = Patch releases are typically unplanned and may resolve defects or important security issues.
                        * pre-release = A pre-release may include alpha, beta, or release candidates and typically have
                          limited support. They provide the ability to preview a release prior to its general availability.
                        * internal = Internal releases are not for public consumption and are intended to be used exclusively
                          by the project or manufacturer that produced it.

                Cryptographic assets have properties that uniquely define them and that make them actionable for
                further reasoning. As an example, it makes a difference if one knows the algorithm family (e.g. AES)
                or the specific variant or instantiation (e.g. AES-128-GCM). This is because the security level and the
                algorithm primitive (authenticated encryption) is only defined by the definition of the algorithm variant.
                The presence of a weak cryptographic algorithm like SHA1 vs. HMAC-SHA1 also makes a difference.

                        Cryptographic assets occur in several forms. Algorithms and protocols are most commonly
                        implemented in specialized cryptographic libraries. They may however also be 'hardcoded'
                        in software components. Certificates and related cryptographic material like keys, tokens,
                        secrets or passwords are other cryptographic assets to be modelled.

                                                Authenticated Encryption (AE) is a cryptographic process that provides
                                                both confidentiality and data integrity. It ensures that the encrypted
                                                data has not been tampered with and comes from a legitimate source.
                                                AE is commonly used in secure communication protocols.
