EBS Production Worker Candidate Map
A ranked evidence map for Elysium Beat Station production-worker technologies that were researched but not adopted into the current runtime. Includes source links, license constraints, browser support, performance considerations, fallback paths, integration complexity, rejection criteria, and browser-now versus native-shell-later recommendations.

Ranked Candidates
| Rank | Candidate | Review State | Why Not Adopted Yet |
|---|---|---|---|
| 1 | Signalsmith Stretch | USE_POC_FIRST | Requires a bounded WASM quality, latency, and sampler-polyphony benchmark before integration. |
| 2 | WebCodecs AudioDecoder and AudioEncoder | REVIEW | Codec support varies by browser and codec. It should not replace the playback core before proxy-asset benefits are measured. |
| 3 | Essentia.js | REVIEW_LICENSE | Commercial closed-source use requires a licensing decision and worker-based performance benchmark. |
| 4 | Rubber Band Library | REVIEW_NATIVE_LATER | High-quality comparison candidate, but proprietary-product licensing and browser/WASM cost require review. |
| 5 | aubio | REVIEW_LICENSE | Browser use requires a maintained WASM integration and the GPL distribution boundary must be resolved. |
| 6 | Web MIDI API and MIDI 2.0 UMP roadmap | REVIEW_CAPABILITY_PROBE | Browser availability is not uniform. Deterministic MIDI-file import and export must remain the portable baseline. |
| 7 | JUCE native shell | NATIVE_SHELL_LATER | Requires a separate native product architecture, plugin scan quarantine, crash isolation, and licensing decision. |
| 8 | CLAP plugin host | NATIVE_SHELL_LATER | Requires a native host with state serialization, thread correctness, scanning, and crash quarantine. |
| 9 | ARA SDK | NATIVE_SHELL_LATER | ARA extends native plugin workflows and is not a browser runtime feature. |
