There's a slight oily film around a gasket, but no puddle under the car and the oil level hasn't noticeably dropped between checks. A mechanic mentioned it during routine service without saying it was urgent. I don't want to ignore an early warning, and I also don't want to pay for a large repair because a ten-year-old engine isn't perfectly dry. What photos, level checks or symptoms would make you move this from ‘monitor’ to ‘book the repair’?

Photos help most when you take them from the same angle every time. If the wet area is growing or getting fresh, that matters more than one dramatic picture.
Also check after longer drives, not just right after it sits. Some leaks show up only when the engine’s hot and everything expands a bit.

If it’s just a light seep and the level stays steady, I’d usually watch it. I’d move it up a notch if the oil film starts spreading, you see drips after parking, or the dipstick starts dropping between checks.
That’s pretty much how I’d look at it too. The one thing I’d add is to keep an eye on how dirty the underside gets, because a seep can turn into a mess before the level makes it obvious.
