prove2me-logs: the 4 October entry, and a correction on Baker's theorem

The prove2me-logs mission journal carries 4 October from the research side — the barrier on generic data, the dilogarithm dichotomy and the three manuscript results that the same day’s companion note v1.17 machine-checks — and the eight nodes contributed by nickrobbins95, mirrored with credit (fc34d3c). The 2 October Baker entry was corrected rather than extended: M. Karatarakis’s public Lean branch baker (github.com/mkaratarakis/mathlib4, since 25 September) formalises the same DALAG Ch. 4 route with the same step-5 repair, so the proof the entry had recorded as a first is not one — the 1 October survey missed it because code search skips forks (90fedab).
