• If no automated test exists yet, create the smallest reproducible failing verification path first.

Required Evidence Format

• Capture the first failing run and why it fails for the expected reason.
• Show the exact test or verification command used.

RED and initial GREEN evidence captured in detached worktree codex/issue-191-cli-shared-service-20260314075856 at /Users/karsten/Work/Development/intelligentcode-ai/_worktrees/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

Result after GREEN implementation: 4 tests passed, 0 failed.

Covered contract:

• CLI help frames headless automation as the primary surface
• serve and launch are explicitly deprecated side paths
• shared application service exposes diagnostics and catalog snapshots
• CLI doctor/catalog paths rely on the service instead of direct catalog imports
• direct CLI imports of executor/catalog/state/updateCheck for the headless automation surface are removed
