Testing — After Removing the Backfill

Test-facing consequences of the removal described in agent-classifier-backfill-removal-architecture.md. Names and paths match that document exactly.

Why the failing test is deleted, not repaired

The CI failure is:

AgentSpanDeploymentContractEndToEndTest > legacyAgentClassifierBackfillUsesConcreteExecutionTimeBounds() FAILED
    java.lang.NoSuchMethodException: org.conductoross.conductor.ai.agentspan.runtime.service.AgentService.backfillLegacyAgentExecutionClassifiers()

The test obtains the method reflectively:

Method backfill =
        AgentService.class.getDeclaredMethod("backfillLegacyAgentExecutionClassifiers");

There are only two ways to make it green:

1. Re-add backfillLegacyAgentExecutionClassifiers() — explicitly forbidden by review.
2. Delete the test.

Option 1 contradicts the reviewer, so option 2 is the only consistent fix. The test exists solely to characterize the forbidden method; with the method gone it has no subject and is removed with it.

What remains covered

AgentSpanDeploymentContractEndToEndTest keeps all other cases unchanged, including the deployment-contract assertions immediately preceding the deleted test (task-def presence/absence for guardrails, handoff checks, and transfer tasks) and the SDK lifecycle-callback boundary test that follows it. Deployment and classifier stamping on the normal deploy() path are unaffected by this change and continue to be exercised by those tests.

No new test is added: the change removes a capability, and the design goal is a minimal, review-scoped edit rather than a feature.

Verification steps (design-level)

Run from the repository root:

Step	Command	Expected
Module compiles without the removed members	./gradlew :agentspan:compileJava	Success; no "unused" or "cannot find symbol" errors.
End-to-end contract tests pass	./gradlew :test-harness:test --tests '*AgentSpanDeploymentContractEndToEndTest*'	Green; the deleted test is absent and no NoSuchMethodException is thrown.
Formatting normalized	./gradlew spotlessApply	No diff on re-run.

Regression guard

The consistency invariants in agent-classifier-backfill-removal-architecture.md are the acceptance criteria: after the change, no AgentService member named or aliased backfill*Classifiers exists, and no test references such a member. A repository-wide search for backfillLegacyAgentExecutionClassifiers must return zero results in both agentspan and test-harness.
