They do NOT inform me ahead of time of any upcoming hearings;
no "schedules" are provided to me.  Yesterday, first I had heard of a
fourth hearing was at 6 AM yesterday, when a guard told me I had "court".

See "Incarceration Nation" by Fareed Zakaria, Time Magazine

just run the numbers.

Yes, if you review that "indictment" backwards, you get:

( a ) DEMAND for clerk's credentials is protected by the First Amendment,
and was necessitated by the FOIA exemption for the judiciary:  5 USC 551

( b )  the middle group of COUNTs all arise from INvalid "subpoenas" issued by a
panel of federal citizens, but withOUT a Clerk's authorized signature,
in violation of 28 USC 1691

supremelaw.org/stat/62/

( c )  the first COUNT falls because of the above e.g. right to contract
with clients to assist them with preparation of their reply(s) to those
defective "subpoenas"

( d ) case RIGHT ON POINT is U.S. v. Pignatiello (SEC Attorney
entered grand jury room withOUT the OATH required by 28 USC 544).

( e ) lastly, REQUEST TO APPEAR IN WRITING: 18 USC 1504
is protected by the last sentence of the latter statute:
does not prohibit a request to appear before a grand jury:

( f ) U.S. Attorneys have an obligation to convey such communications
