PowerX (service) - Foundation Model Provider Onboarding & Governance

Usecase Overview

• Business Goal: Standardize LLM/VLM/TTS/Embeddings Provider onboarding, secret management, verification, and tenant mapping, ensuring online within 24 hours while meeting security and compliance.
• Success Metrics: Onboarding time ≤24h; health verification pass rate ≥99%; 100% secrets under management and rotation; rollback ≤5 minutes; tenant staged rollout coverage ≥95%.
• Scenario Linkage: Supports SCN-AGENT-MODEL-PROVIDER-001 Stage 1 (Provider Onboarding & Governance), provides capability metadata and health signals to routing and governance usecases.

Summary: This Seed treats Provider registration, configuration, verification, publishing, and operations as an assembly line, ensuring the platform can rapidly introduce new models while maintaining observability and rollback capabilities.

Context & Assumptions

• Prerequisites
  • Scenario document docs/scenarios/agent-orchestration/SCN-AGENT-MODEL-PROVIDER-001.md has defined processes, metrics, and responsibilities.
  • Vault/Secret Manager online with tenant/environment-level secret isolation and audit.
  • Feature Flags model-provider-registry, provider-health-check registered in config center.
  • docs/_data/docmap.yaml SCN-AGENT-MODEL-HUB-001 -> UC-AGENT-MODEL-PROVIDER-001 child node fields consistent with this Seed.
• Inputs/Outputs
  • Input: Provider qualifications, API specs, secrets, quotas and tenant lists, cost/compliance materials, automated verification script parameters.
  • Output: backend/config/agents/providers/*.yaml configs, secret references, health scores, tenant config center deltas, audit records.
• Boundaries
  • Does not include model evaluation, cost governance, Prompt strategies (handled by other sub-scenarios).
  • Not responsible for cross-repo model code implementation, only covers PowerX Registry + Ops deliverables.
  • Training/inference call path performance optimization handled by routing and execution scenarios.

Solution Blueprint

System Decomposition

Layer	Main Components/Modules	Responsibilities	Code Entry Points
service	Provider Registry Service	Handle registration API, YAML template generation, Schema validation, tenant publishing	services/provider/registry.ts
service	Secret Manager Adapter	Receive secrets, encrypt storage, rotation schedules, audit events	services/security/secret_manager.go
service	Provider Validation Runner	Call sandbox, run verification scripts, health scoring and log upload	scripts/ops/provider-validator.mjs
ops	Provider Release Pipeline	Staged rollout, tenant mapping sync, rollback orchestration	scripts/ops/provider-release.mjs

Process & Sequence

1. Step 1 – Intake: POST /internal/providers/register receives Provider metadata, writes to staging config and triggers Schema validation.
2. Step 2 – Secret Management: Secrets encrypted and stored via Secret Manager API, references written to YAML, rotation timer and audit started.
3. Step 3 – Automated Verification: Call provider-validator.mjs to execute function/latency/error rate checks, generate agent.provider.health_signal metrics and reports.
4. Step 4 – Tenant Publishing: Through Provider Registry publish API, push config to tenant config center and Feature Flags, support staged rollout and tenant whitelists.
5. Step 5 – Monitoring & Rollback: Continuously subscribe to health signals and secret rotation events; trigger provider-release.mjs rollback to recover previous version on anomalies.

Contracts & Interfaces

• Inbound APIs / Events
  • POST /internal/providers/register — Accept provider profile, endpoints, tenant matrix; requires agent.registry.write permission.
  • POST /internal/providers/{id}/validate — Trigger or rerun automated verification, can specify capability suites and thresholds.
  • POST /internal/providers/{id}/publish — Publish to tenant config center, supports --tenants, --env, --dry-run.
• Outbound Calls
  • Vault Secret Manager /v1/provider-secrets — Store secrets, failure requires cascading rollback of registration.
  • Tenant Config Service /internal/config/tenants — Write tenant/environment mapping and staged parameters.
  • Telemetry Pipeline agent.provider.health_signal — Report latency, error rate, health scores, and rollback status.
• Configuration & Scripts
  • backend/config/agents/providers/*.yaml — Provider templates, capability tags, throttling, tenant mapping.
  • config/feature_flags/provider.yaml — Control staged enable/disable, degradation strategies.
  • scripts/ops/provider-validator.mjs / scripts/ops/provider-release.mjs — Automated verification, publish, rollback.

Implementation Checklist

Item	Description	Completion Status	Owner
Schema Validation & Template Generation	Define YAML Schema, lint, CI validation	[ ]	Agent Platform Guild
Secret Management & Rotation	Integrate with Vault, implement rotation schedules and alerts	[ ]	Ops Reliability Center
Automated Verification Suite	Expand scripts to cover LLM/VLM/TTS/Embeddings	[ ]	Agent Platform Guild
Tenant Staged Rollout & Rollback	Publish scripts & config center API integration	[ ]	Agent Platform Guild
Observability & Audit	Metrics, logs, events mapped to monitoring panels	[ ]	Ops Reliability Center

Testing Strategy

• Unit Tests: Registry Schema validators, Secret Manager adapters, health scoring algorithms, rollback switches.
• Integration Tests: Sandbox calls to real Providers, verify script outputs, secret write+reference replacement, tenant publishing APIs.
• End-to-End Validation: Full链路 from registration to staged rollout, run provider-release.mjs --dry-run in staging and verify metrics curves.
• Non-functional/Chaos: Secret expiration, Provider latency threshold exceeded, Telemetry delay, confirm automatic blocking and rollback paths.

Observability & Ops

• Metrics: agent.provider.onboard_duration, agent.provider.health_success_total, agent.provider.secret_rotation_total, agent.provider.publish_latency.
• Logs: Registry interface audit, secret reference generation, verification script outputs, tenant publishing events (must include providerId/tenant/env/traceId).
• Alerts: Health score < threshold, secret rotation failure, rollback triggered, config center publish failure; delivered via Ops Pager & Teams channels.
• Dashboards: Grafana「Provider Onboarding」, Datadog agent.provider.*, Vault rotation panels.

Rollback & Failure Handling

• provider-release.mjs rollback --provider <id> --tenant <t> rollback tenant configs and revoke Feature Flags.
• Secret Manager failure directly terminates registration, cleans up YAML references and generates audit events.
• Verification failure automatically marks Provider status as pending_fix, blocks publishing and generates JIRA tickets.
• Config center anomalies use cached previous version configs, restrict new tenant access and notify on-call.

Follow-ups & Risks

Risk/Item	Impact	Mitigation Plan	Owner	ETA
Provider qualification & secret review process not automated	Delayed launch, compliance risk	Introduce form/approval automation, integrate with IAM approval system	Agent Platform Guild	2025-03-15
Verification scripts don't cover multi-region endpoints	Production environment stability uncertain	Configure call samples and timeout thresholds for each region, include in CI	Ops Reliability Center	2025-03-05
