pub const FAILURE_PREFIX: &str = "frust-devtools: service did not start: ";Expand description
The exact substring a shell logs (via format_failure_line) when the
in-app devtools service is compiled in but could not start — a bind refused
by the OS, an ephemeral-port exhaustion, a runtime that would not build. The
human reason follows immediately.
Tooling greps for this the same way it greps for DISCOVERY_PREFIX, so a
session that will never announce a port turns “waiting for a discovery
line…” into the concrete reason instead of an eternal silent wait. Shared
here so the logging side and the parsing side cannot drift.
