# cloud-deployment-unification Specification
## Purpose
TBD - created by archiving change integrate-mcp-nexus-groksearch. Update Purpose after archive.
## Requirements
### Requirement: Node and Worker runtimes expose consistent service entrypoints
The deployment model SHALL provide consistent core entrypoints for Node and Cloudflare Worker runtimes.
#### Scenario: Runtime exposes required endpoints
- **WHEN** either runtime is deployed
- **THEN** it exposes `/health`, `/mcp`, and admin API routes under `/admin/api`.
#### Scenario: MCP endpoint enforces client authentication
- **WHEN** a request is sent to `/mcp` without a valid client bearer token
- **THEN** both runtimes reject the request with an authorization error.
### Requirement: Cross-runtime configuration semantics are unified
The deployment model SHALL define shared configuration semantics for authentication, encryption, routing, and rate limiting across runtimes.
#### Scenario: Shared source-mode configuration produces consistent routing
- **WHEN** equivalent source-mode configuration is applied in both runtimes
- **THEN** both runtimes apply the same provider-routing behavior for search-source tools.
#### Scenario: Shared token rate-limit configuration produces consistent throttling
- **WHEN** equivalent global and per-token rate-limit settings are applied in both runtimes
- **THEN** both runtimes enforce throttling with equivalent rate-limit outcomes.
### Requirement: Deployment guidance includes both production paths and verification
The system SHALL provide deployment documentation for Node and Worker paths, including release-assembly handoff and post-deploy verification steps.
#### Scenario: Operator follows documented deployment path
- **WHEN** an operator follows the production deployment guide for a selected runtime
- **THEN** the guide includes release artifact preparation, environment setup, migration steps, and endpoint verification checks.
#### Scenario: Operator deploys from assembled release artifact
- **WHEN** deployment begins
- **THEN** operators can identify the canonical release output directory and use it as the source for runtime deployment workflows.
### Requirement: Rollout supports gradual enablement and rollback
The deployment model SHALL support staged rollout and rollback for GrokSearch integration without breaking existing Tavily/Brave operations.
#### Scenario: Feature is disabled during rollback
- **WHEN** operators disable GrokSearch integration during rollback
- **THEN** existing non-Grok tools remain available through `/mcp` under existing token governance and rate-limit controls.
