First off, if I wrangle and mangle the message files directly, do I have to worry about the indexes, or do the indexes "magically" repair themselves in cases where the messages are either altered (including headers) or removed?
Never ever modify a message on file system.
You can remove and add messages with no problem, the next time the mailbox is accessed, the indexes are repaired.
You can move messages to ../tmp (that would be a remove in the sense of the indexes), change the message there, modify the filename a bit, just to be sure, e.g. I add a counter after the hostname part: 1222364652.P11383Q0M620284.<hostname><counter>,S=7215,W=7294:2, adjust S= and W=, and finally move the message back into '.../new' or '.../cur'. That way the message is seen as new one (add). If you do so and if you have more then 26 keywords in the mailbox, the 27th and up are lost, because they cannot be tagged on the filename itself. The indexes are repaired as well.
