• Two reviewers for a planned subset

Pre-register the decision and observation window

Flaky-Test Quarantine Selection-Bias Research stage 1 tests whether quarantine decisions hide unstable high-risk tests while leaving an apparently healthier suite. The eligible population is test executions, quarantine proposals, removals, retries, failures, owners, and releases. Freeze the decision rule, time window, inclusion criteria, exclusions, unit of analysis, and owner before inspecting outcomes. Retain stable identifiers for source events and transformations so reviewers can distinguish a real absence from collection loss, late arrival, or a changed definition. This protocol supports a bounded engineering decision; it does not certify a platform, vendor, team, or control.

Flaky-Test Quarantine Selection-Bias Research stage 1 reports eligible, observed, excluded, unavailable, late, conflicting, and unresolved counts separately. Stratify by service, risk, environment, client, region, and outcome only where those fields were defined before analysis. Compare retained and missing records, repeat a planned subset with an independent reviewer, and publish disagreements rather than forcing consensus. Any correction appends a versioned note and preserves the earlier result.

Flaky-Test Quarantine Selection-Bias Research stage 1 protects secrets and personal or customer data through approved references, minimum fields, role-based access, retention limits, and synthetic fixtures where possible. Developers may implement queries and evidence tooling, while data, security, service, and release owners approve access and action. The conclusion states the exact versions, window, limitations, and next verification; causal or population-wide language is prohibited unless the design actually supports it.
