Playbooks

Crashtest never opens a socket - it hands handlers in-process Requests. So the only thing a playbook needs to answer is: how does my app receive a request without listen()?

Every playbook produces a config that supports:

$ npx crashtest run    # exit 0 holds, 1 finding, 2 config problem

Pick yours:

• Plain Handlers - handler functions already shaped like Pages Functions (the fastest path: usually zero glue)
• Express - real app.handle() dispatch
• Hono - via app.request()
• Fastify - via app.inject(), after ready()
• Raw Node Servers - undecorated http.createServer handlers, per-route adapter
• CI Gate - one composite step that turns the ledger into branch enforcement
