Summary

• Parameterize the existing ANC hotfix E2E flow with the exact ANC package version published by orchestration.
• Exercise the real node-side repository download path and assert the expected hotfix binary is downloaded, selected, and executed without package-manager fallback.
• Preserve the fixed-version ANC regression scenario for ordinary runs; require an explicit target when release validation is requested.
• Document the pipeline inputs and behavior.

Validation

• go test ./config ./runner -count=1
• go vet ./config ./runner ./scenario
• ShellSpec e2e runner script tests (5 examples)
• Focused ANC scenario/fixture tests

No live cloud E2E was run.

🟢 Approval recommended

The scoped E2E parameterization preserves existing defaults and has no identified blocking issues; live cloud validation remains unperformed.

No open issues 🎉

What changed in this PR

Parameterizes AgentBaker’s existing ANC hotfix E2E scenarios to validate an exact published package while preserving the fixed-version regression default.

Changes:

• Adds CLI and environment inputs with version validation before Azure initialization.
• Shares resolved versions across binary compilation, fixture injection, and assertions.
• Updates tests and documents release-validation inputs and constraints.
