description	Investigate a CorgiSpec change, its planning context, implementation state, and GitHub tracking without modifying anything. Use for read-only exploration when the normalized tracking provider is GitHub.

Explore a GitHub-tracked change

1. Resolve the change and isolated worktree with references/worktree-discovery.md when required.
2. Run corgispec status "<change>" --json and corgispec apply "<change>" --json from the selected worktree.
3. Require matching changeRoot plus artifactPaths, contextFiles, taskArtifactId, trackingProvider, and trackingProviderSource. Stop and request a CLI upgrade when absent.
4. Require trackingProvider: "github"; never infer provider from schemaName.
5. Read planning material only from returned concrete paths. Accept an external store root and never reconstruct a path or artifact role.
6. Inspect relevant implementation, tests, Git history, and worktree state without editing them.
7. Read tracker identifiers at <changeRoot>/.github.yaml, then query live issues for current labels and discussion.
8. Present findings, evidence paths, uncertainties, and possible next steps. Make no file, issue, label, branch, or worktree changes.
