SDP Mapping View — EV2 Rollout Config Visualizer

A VS Code extension to visualize, validate, and inspect EV2 rollout ring configuration files (*.Ring.*.jsonc).

Features

Interactive tree showing Geography → Region → Stamp deployment hierarchy
Collapsible nodes — click ▼/▶ to expand/collapse geographies and regions
All envConfig fields resolved and displayed inline per stamp (environment, subscriptions, DNS, ACR, replicas, Cosmos DB locations, etc.)
Stamp overrides visually separated with orange highlighting
Nested JSON values (e.g. cosmosDatabaseLocations) rendered as readable inner cards with key-value rows
Country labels and summary statistics (geographies, regions, stamps, env configs)

Click any geography, region, or stamp card to jump to its definition in the source JSONC file
Click an envConfig reference (e.g. us_prod ↗) to scroll the env table to that row and navigate to the envConfig definition in the source file
Click any env table row to navigate to that envConfig in the source file

Bottom panel with a comprehensive table of all envConfig entries
18 columns covering every field: environment, appEnvironment, ASP.NET, primary/secondary/nonPrimary regions, DNS, parentDNS, ACR, replicas, subscriptions, IDs, instance, storageSKU, CosmosDB

Errors and warnings appear in VS Code's Problems panel as you edit:

Category	Examples
Errors	Missing `componentSubscriptionId`, invalid GUID format, broken `$(envConfigs.*)` references, `stampCount` mismatch, `MinReplicaCount > MaxReplicaCount`
Warnings	Missing `environment`, unused envConfigs, duplicate subscription IDs (copy-paste), missing `acrName`
Info	Unknown Azure regions, regions shared across rings

Auto-completion and hover docs for *.Ring.*.jsonc files via bundled JSON schema.

Command	Description
`SDP: Visualize Rollout Config`	Open visualization for the current ring config file
`SDP: Visualize All Ring Configs in Folder`	Render all ring configs in a folder side-by-side (Production / Test tabs)
`SDP: Validate All Ring Configs in Folder`	Run validation across all configs and report issues in Problems panel

Open any *.Ring.*.jsonc file (e.g. Prod.Ring.Medium.jsonc)

The visualization opens in a side panel with the full topology tree
