Seriesfence: Metrics Audit

Seriesfence is a focused metrics-governance desk for observability teams facing expensive cardinality surprises and fragile alerting. Turn local Prometheus exposition and rules evidence into a prioritized, editable review with explicit assumptions, ownership, and exportable decisions. KEY FEATURES - Native Prometheus exposition and rules import and normalization - Interactive cardinality fence - Editable metric families with owners and evidence - Deterministic series risks scoring - Current-versus-proposed state comparison - Decision log with accountable disposition - Portable metrics governance packet export - Private offline workspace with no account - Native structured-file or CSV import - Local PDF, workspace JSON, and domain-artifact export - 48 original offline technical reference plates - No account, ads, analytics, tracking, IAP, or subscription Seriesfence estimates risk from imported and recorded metric evidence; it does not query Prometheus, execute PromQL, or calculate exact active-series cost. Validate with current TSDB, scrape, and rule telemetry.
