browser/openspec/changes/establish-development-runtime-baseline/proposal.md

Why

The repository currently has architecture documents and ownership directories, but it does not yet have runnable project baselines. Later platform, run, frontend, and plugin changes need consistent local commands, package boundaries, and verification entry points before business behavior is implemented.

What Changes

• Establish Go module baselines for platform/ and run/ with minimal executable entry points and tests.
• Establish a TypeScript/Vite baseline for platform_web/ with a minimal browser-rendered management console shell.
• Establish a TypeScript baseline for plugins/ covering SDK exports, schema validation scripts, examples, and contract tests.
• Add root orchestration scripts for build/test/check workflows without placing implementation code outside the matching project roots.
• Document local development commands and required tool versions.
• Extend structure verification only for new required baseline files and directories introduced by this change.

Capabilities

New Capabilities

• development-runtime-baseline: Runtime, tooling, command, and verification baseline for the four project roots.

Modified Capabilities

• None.

Impact

• Affects platform/, run/, platform_web/, plugins/, root documentation, and root verification scripts.
• Introduces Go and npm-based development commands but does not implement platform business APIs, run job execution, plugin marketplace behavior, or full frontend pages.
• Future OpenSpec changes will rely on these commands for tests, builds, and local walkthroughs.
