A former consular office explained annotations on reddit:
a "borderline" visa issuance in terms of the consular officer's judgment call when the visa was initially issued, but not suspicious enough to deny entry. So they were just making notes to check up on it later.
It was basically one officer communicating to a future officer, "hey, you might want to give this one a second look if they visit again."
So there. Your visa is valid when it says it's valid and it is perfectly normal to present yourself one day early. But if you were to present yourself after 29 Dec for admission then you can expect closer scrutiny, likely a secondary inspection. While secondary inspection is extremely daunting, it is not an automatic denial, I was sent into secondary once and less than a year later I was admitted into a "trusted traveler" program even. For example, if you were presenting paperwork showing your original vacation was an organized tour which was cancelled and they rescheduled you and this new date is still covered by the visa validity then I'd expect they would let you in.
