Executive Summary

This optional scenario serves group or multi-tenant operations. It provides plugin version drift detection, policy-based alignment, and organisation-wide compliance reporting. The system detects deviating tenants within ten minutes, launches automatic or semi-automatic remediation, and retains a full execution and notification trail.

Scope & Guardrails

• In Scope: Cross-tenant version aggregation, policy configuration, drift detection, task orchestration, notifications, and reporting.
• Out of Scope: Per-tenant grey rollout details, compatibility exceptions, offline import.
• Environment & Flags: plugin-multi-tenant-sync, plugin-version-governance; relies on the tenant directory, version governance service, notification/audit systems, and group policy configuration.

Participants & Responsibilities

Scope	Repository	Layer	Responsibility	Owners
core-platform	powerx	ops	Cross-tenant version view, policy enforcer, drift detection, report export	Matrix Ops (Platform Ops Lead / ops@artisan-cloud.com)
tenant governance	powerx	ops	Group policy setup, notification templates, upgrade task coordination	Erin Xu (Enterprise Tenant Admin Lead / admin@artisan-cloud.com)

End-to-End Flow

1. Stage 1 – Snapshot & drift detection: Aggregate plugin versions across group tenants and compare them with policy baselines.
2. Stage 2 – Policy evaluation & conflict check: Evaluate conflicts with other policies or exemptions and produce an actionable list.
3. Stage 3 – Execution & notification: Launch upgrade tasks or send reminders to deviating tenants and track progress.
4. Stage 4 – Compliance reporting: Generate the group-level compliance report capturing policy matches, execution results, and outstanding items.

Key Interactions & Contracts

• APIs / Events: POST /internal/version/governance/snapshot, POST /internal/version/policy/enforce, EVENT plugin.version.policy.alert, POST /internal/version/policy/report.
• Configs / Schemas: config/version/policy_profiles.yaml, config/version/multi_tenant_baselines.yaml, docs/standards/powerx-plugin/release/Group_Governance_Guide.md.
• Security / Compliance: Respect tenant isolation and authorisation; cross-tenant views are only accessible to authorised personnel; retain reports ≥365 days; conflicting policies require human confirmation.

Usecase Links

• UC-DEV-PLUGIN-VERSION-MULTI-TENANT-001 — Cross-tenant version governance.

Acceptance Criteria

1. Drift detection latency <10 minutes, with execution logs covering tenant, plugin, target version, and owner.
2. Policy conflict simulation is supported with manual decision entry; conflict reports achieve ≥98% accuracy.
3. Compliance reports export by plugin, tenant, and policy with outstanding actions and follow-up plans recorded.

Telemetry & Ops

• Metrics: version.policy.drift_total, version.policy.enforced_total, version.policy.conflict_total, version.policy.compliance_rate.
• Alert thresholds: Policy enforcement failures, drifts not closed within SLA, abnormal conflict spikes, report generation errors.
• Observability sources: Version governance logs, policy enforcer telemetry, workflow-metrics.mjs, group compliance dashboards.

Open Issues & Follow-ups

Risk / Item	Impact	Owner	ETA
Policy conflicts need richer simulation & reminders	Execution efficiency	Matrix Ops	2025-12-22
Group notifications must integrate external collaboration tools	Collaboration efficiency	Erin Xu	2025-12-18
