Proof: npm test passed 159/159; focused node --test for service-snapshot-summary and ops-sentinel static coverage passed; failed rollout showed ops-sentinel could not import src/core/service-snapshot-summary.mjs and this commit adds the module plus regression coverage.
Assumptions: Forgejo main push remains the deployment path; no manual kubectl reconciliation is needed because the failed rollout will be superseded by the repo workflow.
Still fake: no live funds movement; production rollout evidence still depends on the follow-up Forgejo deployment completing.
