At the same time, doing another reading of the anode wire is showing stable continuity when I flex the cable, so I'm inclined to believe that's actually fine, but I'm also getting no continuity across that cable when I measure from the opposite side of the resistor. Is that normal, or is the resistor suspect?

Is that continuity test on your meter a GO/NO-Go kind of thing? Is the indication a tone or light going on? If the test is this sort, then you must realize that the meter has a threshold to determine the result. If the threshold is below 1K then when you measure something with a resistance of 1K the meter will call it an open.
If the boost voltage on the CRT is that low it probably would prevent the beam from lighting the screen. It also would suggest that your HV was low. If the horizontal frequency is far off it would decrease the HV.
