Research direction

Read packages/domain/src/lib/scheduler.ts to see how placeReplica produces rejection codes, then check the existing test patterns in scheduler.spec.ts. Add a unit test for each listed code and run pnpm nx test domain. Done means each code produces a short operator-facing English sentence, with no framework import in the domain package.

Description

enhancement good first issue priority:P3 track:control-plane

placeReplica in packages/domain/src/lib/scheduler.ts returns one code per rejected node (not_ready, architecture, labels, not_allowed, volume, cpu, memory, ports).

Task

  • Add a pure describeRejection(code, nodeName) that returns a short English sentence for operators, for example "edge-1 does not have enough free memory".
  • Add a unit test per code in scheduler.spec.ts.

Acceptance

pnpm nx test domain passes. No framework import in the domain package.
