test(e2e): promote checker baseline before restore check

[gfyrag]

Summary

• archive the restored successor chapter before running CheckStore
• wait for the archived state and the node-local baseline promotion window
• retain the non-vacuous logsChecked > 0 assertion and residency checks

Root cause

The failing cluster E2E job called CheckStore after CloseChapter. A close only stages the checker baseline; ConfirmArchiveChapter promotes it to the live baseline matching the archived boundary. With no live baseline, the checker correctly skipped entry-by-entry verification and reported logsChecked = 0.

The ARCHIVED row is published before the node-local promotion hook completes, so the test retries CheckStore across that narrow post-commit window instead of sleeping.

Validation

• env -u GOROOT GOCACHE=/tmp/ledger-e2e-gocache-1850 nix develop --command go test -race -tags "e2e,s3" ./tests/e2e/cluster -run TestCluster -ginkgo.focus="Restore chapter registry" -ginkgo.v -count=1 -timeout 5m
• GOCACHE=/tmp/ledger-agent-check-gocache-restore-baseline bash scripts/agent-check

✅ Approve — automated review

The change correctly archives the restored successor chapter, waits for archival, and retries the store check until baseline-backed verification occurs. No actionable regressions were found.

No findings.
