1 That's fantastic. I want to see the rest of it.

2 Mina Smith?  Am I missing a reference?

It kind of reminds me of H. Beam  Piper's Paratime Police stuff.  Not bad at all.

You wrote this the same week you were trying to write your own SQL language?  The Handicapper General's gonna come get you if you're not careful, Harrison.

3 I haven't actually read any Piper in decades.  I'm sure there's a germ of an idea or three borrowed from there, as well as the whirling SF cosmos in general.  Mina Smith is the protagonist in the original (similarly fragmentary and unpublished) stories I've set in the same universe, but earlier in the timeline, and as I indicated, a customs agent tasked to stamp out paratemporal contraband.  If she's not retired by this point, she's probably a very senior figure in the Agency.

There's an awful lot that our accountant friend doesn't know, for all his advanced tech.

It's not a SQL language, though, just a programmatic database with some nice query-by-example features.  Intentionally not Turing-complete.  Though of course every protocol evolves until it is...
