Error Model

The error model for bijux-canon-runtime should reveal how the package fails when acceptance, persistence, replay, and governed execution goes wrong. Hidden failure semantics make later layers absorb problems they did not create.

What To Check

• name the failures that belong to this package role
• separate local failure handling from failures that must cross a package seam
• treat recovery shortcuts that hide ownership as design debt

First Proof Check

• src/bijux_canon_runtime/application/execute_flow.py, model/, and observability/ for the structural ownership boundary
• tests for acceptance, replay, and persistence evidence for executable confirmation that the structure still holds

Bottom Line

If bijux-canon-runtime needs hidden structure to defend acceptance, persistence, replay, and governed execution, the architecture is already too opaque.
