GREEN verification is clean in detached worktree codex/issue-191-cli-shared-service-20260314075856.

Focused command:

npm run clean:compiled-tests && ./node_modules/.bin/tsc -p tsconfig.json && node --test dist/tests/installer/cli-shared-service-red-phase.test.js dist/tests/installer/bootstrap-launch.test.js dist/tests/installer/cli-serve.test.js dist/tests/installer/cli-skills-publish.test.js dist/tests/installer/installations.test.js

Result: 18 tests passed, 0 failed.

This verifies the shared-service-backed headless CLI slice for help text, diagnostics/catalog snapshots, skills/source commands, and installation listing.
