LiveView Playbook

HARD-GATE

• A LiveView contract and failing live/2 or live_isolated test must exist before implementation.
• The test must fail because behaviour is missing, not due to config/syntax.
• handle_event/3 and handle_info/2 remain thin; no Repo calls inside LiveViews.
• Implementation requires explicit user approval; full suite and Credo/format must pass.

When to use

New LiveView pages/features or substantial LiveView behaviour changes.
