Week 5 is in the books, and we’ve shifted focus to making sure the developer infrastructure is robust, secure, and ready to scale.

What shipped this week

Self-Serve Developer Portal: Deployed the keys manager worker. Developers can now authenticate securely using their Supabase identities (JWT asymmetric signature checks) to create, rotate, and revoke their own API keys.
Billing Webhook Automation: Wired the Stripe Checkout webhook handler. Stripe checkout events (checkout.session.completed) now trigger instant tier upgrades to the Builder tier ($29/mo) in the Cloudflare D1 database.
Harmonic Precision fixes: Remediated edge case chord spelling calculations in the core engine, securing deterministic accuracy on scale recommendation lookups and functional Roman numeral analysis.

10 seconds of audio → detected key (the wedge app). Simplest THIRI surface; its result enriches a track's on-chain record.

Next Up

Moving into the Seeker apps, starting with the on-device pitch detection integration for the Key Finder frontend.
