Your description of the scope of properties is not quite right. Properties are available:

 - for ALL files of ONE revision (revision properties, note the name change)

 - or for one file (or directory) in a specified revision and all subsequent versions (versioned properties)

Other than the name changes, the point is that you can *specify* a versioned property with exactly the granularity you want here, but it also applies to later versions (which you don't want).

A common way around this is to make the value of the property name the revision, so

> foo.c rev. 44 - PEER_REVIEWED_OK = 44
> foo.h rev. 42 - PEER_REVIEWED_NOK = 42
> foo.h rev. 43 - PEER_REVIEWED_OK = 43

Or, let me renumber and reorder your example slightly, to make the point:

> foo.h rev. 42 - PEER_REVIEWED_NOK = 42
> foo.h rev. 44 - PEER_REVIEWED_OK = 44
> foo.c rev. 46 - PEER_REVIEWED_OK = 46

The interpertations:

r42 has NOK value 42, and no OK value. It was reviewed and rejected.

r43 has NOK=42, no OK. Since there's no matching property value, rev 43 has not been reviewed at all.

r44 has NOK=42 and OK=44: an OK value matches its revision, so it has been reviewed and accepted, and if anyone cares, the last time it was rejected was r42. (Your process might choose to remove the NOK when planting the OK, and vice versa, so there's at most one value at any time, but I'll skip that part for the moment.)

r45 has NOK=42 and OK=44. Neither matches its rev number, so it is unreviewed

r46 has NOK=42 and OK=46: the OK value matches, so this is reviewed and approved.

A conceptually simpler technique is to remove both OK and NOK whenever they no longer apply, so an un-reviewed change would have neither, and a reviewed change would have exactly one.
