…view

The Active Agents companion now tracks the selected session, exposes a native SCM input plus matching header commit action, and stages the target worktree with the existing lock-file exclusion before committing. Focused tests now cover the selected-session commit path and the no-selection info message.

Constraint: Keep the existing ACTIVE AGENTS / CHANGES tree layout intact
Constraint: The SCM commit path must exclude .omx/state/agent-file-locks.json during staging
Rejected: Prompt for a worktree on each commit | breaks the selection-scoped SCM flow the view already establishes
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep vscode/guardex-active-agents and templates/vscode/guardex-active-agents in sync whenever this companion UI changes
Tested: node --test test/vscode-active-agents-session-state.test.js; openspec validate agent-codex-vscode-active-agents-scm-commit-input-2026-04-22-10-55 --type change --strict; openspec validate --specs; git diff --check
Not-tested: Live VS Code extension-host smoke with a real SCM container
