I'm not going to engage in a lengthy debate over the rest of the post, but simply note that the long provenance of a "Rule Zero" in RPGs is fairly simple- that the rules are guidelines, and that the DM doesn't have to follow the rules.
Different games have different ways of putting forth the "Rule Zero," but to the extent that we are discussing "Rule Zero," it isn't about things not covered in the rules, but about adjusting, changing, modifying, or ignoring the rules as needed to enhance gameplay (aka "fun" for the group).

Technically, the ability to detect invisibility (absent special circumstances or a spell) was a product of both you level/HD cross referenced with your intelligence; this has nothing to do with being human. Then you'd roll on the appropriate Gygaxian table in the DMG. The intelligence part was explained as being able to analyze the disturbances in the air, the smell, etc. The level ... eh, because.
As dogs have less than 7 hit dice, they could not detect an invisible creature.
IIRC this was around page 50-60 in the DMG, near the vision section.
The bigger point is not that the DM makes a ruling on the fly, but that she makes the same ruling if and when the same situation arises again.My point is that when you as the DM exercise your rights under "Rule Zero" to alter the rules on the fly - I may well agree that the rules give you that right - but exercising "Rule Zero" in that context is inherently fraught with risk. Among those risks is that the player may perceive, with cause, that the DM changing the rules at that moment is not being impartial, fair, and consistent.
As long as the player is given a chance to then propose a different action, this seems fine to me.Consider what might have happened if, in the middle of the session, right when a PC had been covered by a swarm, and right after the player had proposed an action in response, the DM had decided rather than to just go with the illogic of the scene, that he was going to rule that - in the interests of verisimilitude - that the swarm was immune to weapon attacks.
