So, re-washing didn't help. It appears, as was suggested elsewhere, that what I'm seeing is a chemical reaction, probably between the plastic of the sleeve and the emulsion side of the negative. The images in question have been in the "archival" sleeve for about 35 years...
Or it was something in the environment to which the plastic was porous. I've been in one house and three apartments in that period, and though I aimed for a cool, dry, dark place for storage ... Who knows?
Thanks again for your thorough response,

When you said your negatives were dirty, we thought they were dirty and tried to advise you accordingly. If I, for one, had known that the actual problem was emulsion deterioration, I would not have advised any kind of cleaner or, in particular, a solution which could soften the emulsion and only cause more damage. I think the best you can do now is let them dry, make the best copies you can, and correct your mistakes in post. Good luck!
