Appendix A — Planned features

Caution

This appendix is non-normative. The features named here are design directions, not part of the normative Bynk language. They are not implemented in the version this specification defines, are subject to change, and impose no requirement on a conforming implementation. They are recorded only to mark intended direction.

Two directions are designed but not yet shipped:

• Events — first-class domain events a context can publish and others react to, beyond the present synchronous consumes call.
• Sagas — long-running, multi-step workflows with compensation, coordinating effects across contexts.

Two named follow-ons extend agent invariants (shipped runtime-checked in v0.80):

• Static provable-violation analysis — a compile-time error for a handler all of whose paths provably commit a state that violates an invariant; a layer on top of runtime checking (static satisfaction proving remains further deferred).
• A general typed-agent-fault channel — making an InvariantViolation (and every other uncaught agent fault, such as a non-exhaustive match) a caller-distinguishable fault envelope, rather than the present bare 500. The surface stays a fault, never a Result variant.

These are sketches of intent, not specifications: this appendix deliberately states no syntax or behaviour for them. For the design rationale and the current thinking on what is deferred, see Versioning & roadmap.
