Research question and boundary

Deployment Rollback Verification Delay Study asks whether rollback duration measures include destination verification and residual-state reconciliation rather than only the rollback command. Stage 1, research question and boundary, declares one production change linked to trigger, rollback decision, execution events, health observations, residual checks, and verified recovery as the observation unit and freezes population, system boundaries, local and UTC times, source versions, inclusion rules, exclusions, and intended decision before outcomes are reviewed. Record DO-R-1013-01 distinguishes system events, engineering interpretations, owner decisions, implementation evidence, and unresolved hypotheses. This prospective protocol reports no completed client outcomes and defines no universal performance benchmark.

At stage 1 for Deployment Rollback Verification Delay Study, include routine, missing-source, wrong-identity, conflicting-version, late-arriving, inaccessible-system, unavailable-owner, reversed, corrected, reverted, and reopened cases. Two reviewers classify a stratified subset independently using written anchors, preserve first-pass disagreement, and adjudicate against retained evidence. Report numerator, denominator, exclusions, null values, age bands, correction rate, disagreement, and residual cases together. Alternative explanations include configuration, case mix, cache state, clock drift, synchronization, sampling, ownership changes, release versions, seasonality, and selection effects. The ten public sources guide control design but do not inspect this system, establish causation, certify a provider, or authorize deployment. Preserve protocol, queries, codebook, fixtures, sample receipt, chronology, reviewer notes, decision log, approved action, verification, limitations, and refresh trigger so another authorized engineer can reproduce the bounded result without retaining secrets or unnecessary production data.
