How fast can you fix a Laravel bug?

Emergencies (app down in production) get a first responder on the stack trace during my working hours (10 AM to 7 PM IST, Monday to Saturday). A single well-scoped bug is typically fixed and tested within 24-48 hours. Deeper root-causes, an intermittent MaxAttemptsExceededException, a memory leak, an N+1 query storm, take a little longer because we reproduce, profile, and add a regression test, but you get a written ETA up front.
