🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Handle unknown migration phases explicitly.
MigrationPhase.Terminal() returns false for an unknown value. migrationPhaseRank returns 4 for that same value. As a result, MigrationPhaseAtOrPast reports that an unknown phase has passed every Manual phase.
Give unknown phases an explicit rank or result. Add a regression test for an unknown MigrationPhase.

Apply the explicit non-empty reason override.
A container in CrashLoopBackOff can also have a prior non-zero LastTerminationState. PodTermination selects that prior termination first. This branch then keeps the prior reason and discards the explicit reason classified by the stuck-pod escalator.
Replace the extracted reason when reason is non-empty. Add a regression test that combines a non-zero last termination with a current waiting state and verifies that PodTerminationWithReason returns the supplied reason.

Addressed, and rebased onto latest Major — restrict exit-zero termination selection to failed Pods. Fixed, and thank you — this one was real and reachable. Step 3's own doc comment said "exit 0 but the pod is Failed", but the code had no phase guard, and Major — apply the explicit non-empty reason override. Declining; I believe this one is incorrect. The current precedence is the documented contract ("When PodTermination DID extract a record but with an empty Reason, the override fills it in"), and it is already pinned by an existing test asserting that an Minor — expire expectations at the exact deadline. Fixed: Minor — handle unknown migration phases explicitly. Fixed. The terminal phases are now enumerated at rank 4 and the Minor — the two Minor — correct the nil-return contract. Fixed: Verified: One housekeeping change while amending: added the DCO |

First slice of the InferenceReplica runtime, which is the piece that makes
OMENativeactually render pods. Authored by @slin1237; I am porting it.What this is
The vocabulary the rest of the runtime is written in: the per-Instance plan and operation kinds, Instance and Runner status shapes that mirror the CRD field-for-field, retry-block and expectations bookkeeping, migration and termination records, event reasons, condition helpers, and the dependency and service seams the reconciler is constructed with.
Why it is first
It imports no OME packages at all — only the standard library, k8s API machinery and controller-runtime — so it stands alone, builds and tests on its own, and every later slice can be reviewed against a type vocabulary already in the tree.
Nothing in the tree consumes it yet. That is deliberate: the alternative is one very large PR.
The wave this belongs to
The dependency graph is a clean DAG, so the remaining slices land in topological order:
Together those are what turns an
InferenceReplicainto running pods, plus PodGroup creation and gang admission — the gaps documented in #770.Verified
