\section{Implementation}


\subsection{System Architecture}

Earle comprises four components:

\begin{enumerate}
\item \textbf{Genome Manager}: Stores and versions campaign genomes.
\item \textbf{Evolution Engine}: Executes genetic operators.
\item \textbf{Platform Adapters}: Interface with advertising APIs (Facebook, Google, Twitter).
\item \textbf{Analytics Collector}: Aggregates performance metrics.
\end{enumerate}

\begin{lstlisting}[language=Python,caption=Evolution loop]
class EvolutionEngine:
    def run(self, config):
        population = self.initialize(config)

        while not self.should_terminate():
            # Evaluate fitness
            for individual in population:
                individual.fitness = self.evaluate(individual)

            # Selection
            selected = self.select(population)

            # Crossover
            offspring = []
            for p1, p2 in pairs(selected):
                child = self.crossover(p1, p2)
                offspring.append(child)

            # Mutation
            for individual in offspring:
                self.mutate(individual)

            # Replacement
            population = self.replace(population, offspring)

            self.generation += 1

        return self.best(population)
\end{lstlisting}

\subsection{Platform Integration}

Each advertising platform has unique APIs and constraints. Platform adapters translate genomes to platform-specific formats:

\begin{lstlisting}[language=Python,caption=Facebook adapter]
class FacebookAdapter:
    def deploy(self, genome):
        campaign = {
            "name": genome.id,
            "objective": "CONVERSIONS",
            "adsets": [{
                "targeting": self.translate_targeting(genome.targeting),
                "optimization_goal": "OFFSITE_CONVERSIONS",
                "billing_event": "IMPRESSIONS",
                "bid_amount": genome.bid_amount,
            }],
            "ads": [{
                "creative": {
                    "title": genome.headline,
                    "body": genome.body,
                    "image_hash": self.upload_image(genome.image),
                    "call_to_action": genome.cta,
                }
            }]
        }
        return self.api.create_campaign(campaign)
\end{lstlisting}

\subsection{Brand Safety}

Earle enforces brand consistency through:

\begin{enumerate}
\item \textbf{Prohibited word lists}: Filter profanity, competitor names, regulated terms.
\item \textbf{Tone analysis}: Ensure generated text matches brand voice (formal, casual, humorous).
\item \textbf{Visual guidelines}: Validate image colors, composition against brand standards.
\item \textbf{Human review}: Flag unusual variations for approval before deployment.
\end{enumerate}
