Each agent now gets paired song challenges and must write one patch per target; every patch, hypothesis, metric, challenge artifact, evaluator fact, and distillation document becomes curriculum evidence in CultCache/Qdrant. The post-pass distiller writes pruned `.cc` stores with reusable scene roles, transfer rules, failure patterns, kept trials, dropped noise, and aggregate metrics, and retrieval links those distillation chunks back to kept scored trial IDs so future zero-shot production agents can actually receive the distilled context.","evidence":"tools/run-song-snippet-trial-swarm.ps1; tools/IpaTrialWorker/Program.cs; src/AquaSynth.Core/IpaTrialResults.cs; state/scratch.md"}
