doctor

Overview ¶

Package doctor runs tomo's startup preconditions as a set of named checks: the config resolves a usable provider, the data dir is writable, and every configured channel has a driver. Each check hands back a fix in plain terms rather than a stack trace, so a stale config surfaces before it fails at runtime. Both `tomo doctor` and `serve` run these, so serve refuses to start half-configured instead of dying mid-turn.
