Protean roadmap

This post holds Protean's near-term direction. For the exact issues in flight, follow the release milestone linked below.

Now: 0.18, target release date: 01-OCT-2026

Primary directives:

The building experience. protean new becomes a compiler front-end rather than a template stamp. It generates a project that actually runs and passes a new protean verify (init, check, and tests in one command), with a typed diagnostic contract so an error points at the fix, and an Event Model view of your domain rendered from the framework's own intermediate representation.

A verified, operable core. The transaction, dispatch, and checkpoint paths that changed in 0.17 get differential and mutation testing. A first slice of durability lands (event-store verify and checkpoint-consistent recovery), together with single-deployment operability (dead-letter parity, graceful drain, and lag you can actually alert on). An Applicability Charter states plainly when not to use Protean.
