Why: Record the separate one-time A01 resource authorization and fix the exact Backend revision with its own guarded label and output name. Evidence: The selector tests failed before the change and passed afterward. Full Backend vet/Go and selected zero-paid live-tag suites, Dev strict pins and build passed; full new-head CI and preflight are required before any paid call. Impact: Evaluation-only Backend gitlink and task evidence. No provider request, merge or deployment. Refs: U3 r0.4 stage-6 conclusion and one-time A01 resource proposal; Backend PR #193
