Let's finish DC of old "dubious" claims of primes

[kriesel]

I think the term "shout-out" does not apply there, as it generally means a positive mention, relating to an accomplishment, neither of which apply regarding your minimal and misguided involvement with M384989999. https://www.dictionary.com/browse/shout-out https://dictionary.cambridge.org/dic...lish/shout-out etc.
M384989999 which you assured us was prime has already been found composite, but that run apparently lacked a proof file uploaded to the server, so I am independently verifying it as composite with a run that should produce an uploadable proof file for additional verification of complete and accurate computation, as I do with all feasible predictions of Mxx or other "dubious" claims. ("Dubious" being a polite substitute for some more-descriptive adjectives. You wrote it first: "spewing uneducated rubbish here". In this forum there is in general a low tolerance for nonsense.)

[kriesel]

Combined list update: Predict Mxx lacking completed DC, and dubious claims lacking completed DC, but within range of feasible P-1 factoring, yields 2 uncompleted exponents (for now). Current status of each, plus a recently completed follows:

M384989999 (a particular dubious claim) TF & P-1 factoring completed,
ShenTianYing reported a poached composite result 2022-09-01, apparently without proof generation. Its LSBs remain masked, but the unmasked bits are matched by a subsequent DC. Kriesel completed DC PRP with proof generation 2022-10-01. Naegi Makoto completed the cert for it successfully 2022-10-13. M384989999 is conclusively proven composite.

----limit of mersenne.org current server hardware automatic handling of proof files is ~ 596M----
----limit of mersenne.org exponent range 1000M----
M1000000007 (from predict M52 list) TF and P-1 done; Kriesel is running a first PRP/proof, feasible in ~4.5 months in Gpuowl on a Radeon VII, now 8.9% complete.
----limit of mprime/prime95 AVX512 64M fft exponent handling (PRP, proof, cert,...) 1169M----
----limit of available PRP/proof-capable gpuowl versions 2172.36M----
M2252945257 (from predict M51 list) TF done, Mlucas P-1 stage 1 NF, stage 2 running at ~39.7% completed now, total time for both stages estimated at 9.8 months on an Intel i5-7600T; no first PRP test yet, waiting on P-1 GCD results, then wait for Mlucas V21 proof capable version release (but run time would be very long on any CPU hardware I have. A modified Gpuowl with >120M fft length might complete it in ~2.8 years on a Radeon VII. And there is no proof file upload destination or Cert assignment or processing capability for such a large exponent, which would require adding ~128M fft in prime95.)

It's LSBs are masked in the PRP section, but not in the History section (where they match Kriesel's DC). Which looks like a server glitch.
