It feels like the pollution detection technology should be behind the circuit network tech since the pollution detector requires a constant combinator as an ingredient.

Holmium plate productivity feels like it should require holmium processing. I see that it does require planet discovery fulgora at least, so you're likely to have it anyway - it's just possible that you don't. This same minor inconsistency also seems to apply to fulgoran cryogenics. Maybe planet discovery cerys should just require electromagnetic science packs instead?

Mixed ores is unsorted within Factoriopedia.

After adding this modpack to an existing save and researching planet discovery moshine, both the magnetism and silicon trigger techs immediately got researched as well, before I even went to the planet to mine the mixed ores.
