Usecase Overview

• Business Objective: When plugins have security or compliance risks, provide approvable, fast, and auditable suspension capabilities, while retaining complete evidence chains to support subsequent investigation and recovery.
• Success Metrics: Suspension response time ≤ 60 seconds; forced suspension success rate ≥ 99%; evidence snapshot generation < 2 minutes; recovery approval closure ≤ 24 hours.
• Scenario Association: "Corresponds to main scenario SCN-OPS-PLUGIN-LIFECYCLE-001 Stage 4, covering risk identification, suspension execution, notifications, evidence and recovery."

Through suspension orchestration, forced execution and evidence archiving, ensure risk plugins can be controlled within one minute, while retaining chains for compliance review and supporting approved recovery.

Context & Assumptions

• Prerequisites
  • Feature Flags plugin-safety-lock, plugin-suspend-force, plugin-audit-stream are enabled.
  • Security teams have permissions to submit suspension approvals; ticketing system and audit service are available.
  • Configuration, log, metric storage supports snapshot archiving with sufficient capacity.
  • Notification system supports multi-channel reach to administrators and tenant users.
• Input/Output
  • Input: suspension reason, plugin ID, tenant ID, suspension mode (wait/force), evidence requirements, approval credentials.
  • Output: suspension status, notification records, log/configuration snapshots, audit numbers, recovery approval tasks.
• Boundaries
  • Not responsible for vulnerability fixing or patch development; not covering Marketplace delisting; not including third-party forensics processes.

Solution Blueprint

System Decomposition

Module	Responsibility	Code Entry Point
SuspendHandler	Suspension approval, orchestration, state management, recovery requests	internal/plugins/runtime/suspend/handler.go
ForceExecutor	Forced suspension execution, timeout control, task termination strategies	internal/plugins/runtime/suspend/force_executor.go
NotificationHub	Notify administrators, tenant users, ticketing system	internal/plugins/runtime/notifications/notifier.go
EvidenceSnapshot	Generate log, configuration, metric snapshots, upload to evidence repository	internal/plugins/runtime/evidence/snapshot_builder.go
SuspendAudit	Record suspension/resume actions, approval chains, evidence numbers	pkg/audit/plugins/suspend_audit.go

Process & Timeline

1. Step 1 – Suspension Request & Approval: SuspendHandler receives security team request, validates permissions and starts approval, allowing forced mode when necessary.
2. Step 2 – Execute Suspension: Execute wait or forced suspension, block new requests, handle in-flight tasks, record executor and timestamp.
3. Step 3 – Notification & Evidence: NotificationHub sends suspension notifications, EvidenceSnapshot generates log, configuration snapshots and uploads to evidence repository.
4. Step 4 – Audit & Recovery: SuspendAudit writes audit; if recovery needed, administrator submits request and passes security review.

Contracts & Interfaces

  • EVENT plugin.suspend.completed, EVENT plugin.resume.requested.
• Outbound Calls
  • POST /notify/security, POST /notify/tenant-users — Suspension/resume notifications.
  • POST /evidence/upload — Upload log, configuration, metric snapshots.
  • POST /audit/logs — Record approvals, executions, evidence numbers.
  • POST /tickets/create — Create or update security tickets.
• Configurations & Scripts
  • config/plugins/suspend_policies.yaml — Suspension approval policies, default modes, timeout configurations.
  • config/plugins/evidence_retention.yaml — Evidence retention days, storage strategies.
  • docs/standards/powerx-plugin/security/vulnerability-response.md — Risk response processes.

Implementation Checklist

Item	Description	Status	Owner
Suspension Approval	Support multi-level approval, approval templates, exception paths	[ ]	Matrix Ops
Forced Execution	Provide wait/force strategies, running task termination and timeout handling	[ ]	Eva Zhang
Evidence Snapshot	Collect logs, configuration, metrics, version info and upload to evidence repository	[ ]	Matrix Ops
Notification Channels	Support email, SMS, console, webhook, multi-language templates	[ ]	Eva Zhang
Recovery Process	Dual approval, audit association, operation replay	[ ]	Matrix Ops

Testing Strategy

• Unit Tests: Approval state machine, permission validation, forced suspension execution, notification templates, evidence generation.
• Integration Tests: Execute D-1/D-2 cases from primary.md; verify wait mode, forced mode; simulate evidence storage failures, notification failures.
• End-to-End Validation: Trigger suspension in pre-production environment, check response time, notifications, log snapshots, audit chains; verify recovery approval.
• Non-Functional Tests: Concurrent suspension requests, evidence repository capacity limits, long-running task termination, audit service degradation.

Observability & Ops

• Metrics: "plugin.suspend.response_time, plugin.suspend.success_rate, plugin.suspend.force_total, plugin.resume.approval_duration."
• Logs: "Record plugin_id, tenant_id, mode, requester, approver, status, evidence_id, elapsed_ms."
• Alerts: Suspension response >60 seconds, forced suspension failures, evidence upload failures, recovery approval timeouts.
• Dashboards: "Grafana Runtime Ops / Plugin Safety, audit panel, ticketing system dashboard, notification delivery monitoring."

Rollback & Failure Handling

• Rollback Steps: If suspension fails, automatically retry or escalate approval; on forced failure, trigger alert and lock plugin, block entrance.
• Remediation: Provide manual execution scripts, manual evidence upload; notify security team to intervene; record failure reasons.
• Data Repair: Can regenerate evidence snapshots, supplement audit records; re-send messages to users with failed notifications.

Follow-ups & Risks

Risk/Item	Impact	Mitigation	Owner	ETA
Multi-language notification templates missing affecting international tenants	User experience	Add multi-language templates and include in audit	Matrix Ops	2025-11-24
Evidence repository capacity insufficient causing archiving failures	Compliance risk	Early capacity alerts, auto-scaling, tiered cleanup strategies	Eva Zhang	2025-11-28
