Drive PlaceCal's running local Rails dev server from the terminal without a browser — log in via Devise (CSRF handled automatically), submit forms, inspect Turbo Stream responses, and read the development log correlated by request id. Use this to actually exercise a change and verify it works (per CLAUDE.md's "never claim a fix worked until you've verified it") when the behaviour is server-rendered: a controller action, a redirect, a turbo-stream, the SQL a request runs, or an error in the log. It does NOT run JavaScript (no Stimulus, no DOM morphing) — for those, verify in Claude in Chrome (our standard for lvh.me), or optionally hand the logged-in session to a Playwright MCP via the bridge below. Pairs with static code reading (grep/Read) by adding live runtime interaction.
