Adds the AiStudentPodcastObjective join model and updates the AiStudentPodcast has_many :objectives association to use :through. Adds StudentPodcastPromptHelper, which builds the OpenAI system prompt for student podcast script generation from a lesson plus a selected subset of learning objectives. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds AiStudentPodcastsHelper, which generates a podcast script via OpenAI and converts it to audio via ElevenLabs, then uploads the result to S3. The helper short-circuits when an mp3 already exists in S3, when an existing podcast record already has a saved script, when another user has already generated a script for the same lesson + objective set, or when ElevenLabs credits are exhausted. Includes inner OpenaiClient and ElevenlabsClient HTTP wrappers. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds AiStudentPodcastsController with show and generate_podcast endpoints. generate_podcast deduplicates against any existing podcast record for the same user + lesson + exact objective set before enqueuing AiStudentPodcastsJob, which delegates to AiStudentPodcastsHelper.create_and_save_to_s3 to produce and upload the audio. Both endpoints are gated on the 'lesson-tutor' single user experiment. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

🤔 Does this work? The experiment flag that we're using so far is a url param for a client side "experiment"

My understanding is that you don't have to set up a backend experiment - you just have to add a SingleUserExperiment with that name for whatever user / user subset you want to access the experiment.
