* use fetched_at instead of last_webfingered_at
* catch local "not found" errors. small formatting / error string changes
* remove now unused error type
* return nil when wrapping nil error
* update expected error messages
* return correct url for foss satan webfinger
* add AP model for Some_User
* normalize local domain
* return notretrievable where appropriate
* expose NewErrNotRetrievable
* ensure webfinger for new accounts searched by uri
* update local account short circuit
* allow enrich to fail for already-known accounts
* remove unused LastWebfingeredAt
* expose test maps on mock http client

* use fetched_at instead of last_webfingered_at
* catch local "not found" errors. small formatting / error string changes
* remove nil error checks (we shouldn't be passing nil errors to newError() initializers)
* remove mutex unlock on transport init fail (it hasn't yet been locked!)
* woops add back the error wrapping to use ErrNotRetrievable
* caches were never being started... 🙈
