Soreang-Pasirkoja (T10) has
a couple signs calling it a spur of T4, added in 2019-2021. This does match OSM.
Depok-Antasari (T12) does not seem to have any signs giving it any number. I see where OSM labels it, but without another source, and especially given that it wouldn't fit the numbering if T10 doesn't exist, I'm changing it to JTDA. Similarly, I can't find any T19 signs on Bekasi-Cawang-Kp. Melayu (Becakayu on signs, hence JTB). If sources are found, it'll be easy enough to change back.
