+## 2026-06-17 - Architectural Constraint: Headless CLI
+**Learning:** The vspec repository is a local-first, headless CLI application that exclusively outputs machine-parseable JSON envelopes for AI consumption. It has no web UI or human-readable text format, making visual or text-based UX improvements inapplicable.
+**Action:** Abort task without creating a PR, as no suitable UX enhancements can be identified.
