MCP server under inspection

N/A — this is a static code-review finding against the 2.7.0 tag's source and CI config (docs/quality-gate.md), not a live reproduction against a running MCP server.

Steps to reproduce

Found via static review of the 2.7.0 tag source (docs/quality-gate.md), not a live run.

1. docs/quality-gate.md states that smoke:tui self-skips under process.env.CI because Ink needs a real TTY.
2. It only runs "for real" during npm run local:gate on a developer's own machine.
3. Confirmed this is the documented, intentional behavior — not a flake.

I have not attempted to push a TUI regression through CI to watch it slip through live; flagging based on the documented gap itself.

Expected behavior

The TUI smoke test runs against a real PTY in CI (e.g. via node-pty or a similar terminal emulator driving scripted key sequences), so a TUI regression is caught before merge/release regardless of whether a contributor happened to run local:gate locally.

Actual behavior

smoke:tui self-skips whenever process.env.CI is set, so CI runs currently give zero signal on TUI regressions; the only real execution path is a developer manually running npm run local:gate.

Suggested fix: run the TUI smoke test in CI against a real PTY instead of relying on local:gate as the only real execution path. By the project's own docs, this is the largest gap between what's tested and what ships.
