 Revocation can happen at any time after (5), whether or not step (6) was successful. We do things this way so that even in the event of a power failure or error storing data, we have a record of what we planned to sign (the tbsCertificate bytes of the linting certificate).

-# OCSP Status state machine:
-
-wait -> good -> revoked
-   \
-    -> revoked
-
-Serial numbers with a "wait" status recorded have not been submitted to CT,
-because issuing the precertificate is a prerequisite to setting the status to
-"good". And because they haven't been submitted to CT, they also haven't been
-turned into a final certificate, nor have they been returned to a user.
-
-OCSP requests for serial numbers in "wait" status will return 500, but we expect
-not to serve any 500s in practice because these serial numbers never wind up in
-users' hands. Serial numbers in "wait" status are not added to CRLs.
-
-Note that "serial numbers never wind up in users' hands" does not relieve us of
-any compliance duties. Our duties start from the moment of signing a
-precertificate with trusted key material.
-
-Since serial numbers in "wait" status _may_ have had a precertificate signed,
-We need the ability to set revocation status for them. For instance if the public key
-we planned to sign for turns out to be weak or compromised, we would want to serve
-a revoked status for that serial. However since they also _may not_ have had a
-Precertificate signed, we also can't serve an OCSP "good" status. That's why we
-serve 500. A 500 is appropriate because the only way a serial number can have "wait"
-status for any significant amount of time is if there was an internal error of some
-sort: an error during or before signing, or an error storing a record of the
-signing success in the database.
-
-For clarity, "wait" is not an RFC 6960 status, but is an internal placeholder
-value specific to Boulder.
