Classical Latin to Proto-Romance (which I always thought was just Vulgar Latin, but apparently not)
They're defined differently. Proto-Romance is the reconstructed theoretical earliest common ancestor of modern Romance languages (it's a linguistic concept and refers to a specific dialect that may only be theoretical); Vulgar Latin is the language attested to have actually been spoken by ordinary Roman citizens at any time in Roman history (it's a historical concept and refers to actual dialects, but not necessarily to a single dialect spoken at a single point in time).
Presumably, Proto-Romance or something similar to it was
a form of Vulgar Latin. But there would have been forms of Vulgar Latin that predate PR, and potentially forms that postdate it (that is, very very Early Old French (etc) was perhaps still just a local form of Vulgar Latin). And there's no guarantee (thanks to the confounding forces of areal influence and convergent evolution) that an exact form oof PR was ever actually spoken exactly as we reconstruct it.
But I'm assuming the palatalisation hadn't yet happened in the first century CE since that was still Classical Latin period, right?
Classical and Vulgar aren't different periods, they're different sociolects.
The
literary language goes Old Latin > Classical Latin > Late Latin > Mediaeval Latin
The
vernacular language goes Old Latin > Vulgar Latin > Old (insert romance language here)
Vulgar Latin was contemporary to Classical Latin (and to Late Latin), but was less conservative - phonologically, but more so in vocabulary and grammar. Because it's less conservative, Vulgar Latin can be thought of as evolving out of written Classical Latin (in that you can derive the Vulgar forms by sound change from an assumed language based on Classical spelling), but really they co-existed, both developing out of Old Latin, but Classical Latin refusing to recognise in writing all of the changes that were happening in speech). Late Latin then developed out of Classical Latin largely by the reintroduction of Vulgar Latin elements.
Proto-Romance is a specific but theoretical dialect of Vulgar Latin that would explain all later Romance languages.
The first century CE is indeed in the Classical period - authors of the day wrote in Classcal Latin - but people would actually have spoken (and sometimes written, in some contexts) Vulgar Latin. That is, if you read the graffiti from Pompei, it's not all written the way that Ovid or Seneca would have written.
Specifically, apparently, Pompeiian graffiti indicates that the following was at least potentially the case by the time of the erruption:
- lenition and degemination
- loss of final /m/ and of /n/ before /s/ (the former was commented on by Classical grammarians as a thing, and the latter is found in literary Late Latin)
- epenthetic /i/ added before sC clusters
- syncope of at least some unstressed medial vowels (Augustus did this and found the unsycopated forms pretentious in speech)
- /au/ > /o/ (always a thing, as it occured in Umbrian. Some branches of the Claudian family called themselves Clodians, though the exact significance of this is debated)
- /awi/ > /au/
- /ae/, /oe/ > /e/
- /e/, /i/ > /j/ before vowels
- loss of final unstressed /s/
Note, though, that not every trend found in vernacular speech ends up becoming standard - some die out. For instance, although lenition and degemination became fashionable in Gaul, they actually didn't catch on in the long run in Italy, perhaps because the guys who were witing like this in Italy ended up 'correcting' what had become a class shibboleth, while those in the provinces adopted what they saw as a fashionable Italian accent. It's kind of like the way people from unfashionable places may imitate the colloquial speech of New York or London, without realising that actually in those cities the colloquial speech has already abandoned some of the innovations they're copying...
Anyway, it seems as though at this time the difference between Vulgar and Classical was quite limited in terms of phonology; it was much more substantial in terms of vocabulary.
