I don't think you're
lying. But I do find it frustrating that you seem to be ignoring what I'm posting about how the game works, and making some strange conjectures instead.

I don't know what you don't understand.
Like any conventional RPG, the GM frames scenes, describing the situation to the players that their PCs find themselves in. The players say what their PCs do. And then the rules are used to work out what happens.
When the GM frames scenes, they do so having regard to the priorities that the players have authored for their PCs. For instance, Tru-leigh has the Belief
I will bring Joachim's blood to my master, and so I as GM am presenting situations which prompt the player to declare actions in pursuit of that Belief; those actions are resolved in the ways I've described:
*Tru-leigh and Jobe (the other PC) encounter Halika, the assassin, who is trying to get to Joachim first, and so they drug her (task: concoct a sleeping potion and feed it to Halika; intent: to delay Halika so that Jobe and Tru-leigh get to Joachim first; result: success on the herbalism test);
*Then, Tru-Leigh and Jobe, knowing that Joachim is recovering in Jabal's tower, try to sneak into the tower via the catacombs, but get lost and end up beneath a grate, looking up into a city street, only to see Halika, awakened from her drugged stupor, looking down at them and taunting them, on her way to the tower (task: travel via the catacombs to the tower; intent: to arrive at the tower unobserved; result: failure on the Catacombs-wise test, so the intent is not achieved - they don't arrive at the tower, but rather are spotted by Halika - it's been years since this episode occurred, but my recollection here is that the players took a bonus die for working carefully as they went through the catacombs, which, if it fails, licenses a time-sensitive complication, which in this case was Halika having woken up);
*Tru-leigh and Jobe now race through the catacombs to try and get their first, but Halika beats them (task: race through the catacombs to the tower; intent: get to the tower before Halika; result: failed Speed test vs Halika, so when they get to the tower Halika is already there, and is able to behead Joachim).
In this summary, I'm skipping over the details of the roleplaying, which in any event I don't remember in much detail years later. I'm just focusing on the core events, and showing how they follow the rules and principles set out in the BW rulebook. And as far as those rules and principles are concerned, I hope you can see how I'm following them.
To elaborate on that a bit.
See how, each time the situation is reframed, the focus is still on Tru-leigh's Belief (there was also stuff at stake for Jobe, but I'm skipping over that in this description).
The first obstacle to overcome is Halika, who has her own agenda for Joachim. Tru-leigh succeeds at the attempt to drug Halika, which means that the player's intent is realised: Halika is out of the way. As the GM, I'm not just free to have Halika wake up at a point that I think "makes sense", or is "realistic": Halika is out of Tru-leigh's way, and Let it Ride applies (p 32): "A player shall test once against an obstacle and shall not roll again until conditions legitimately and drastically change. Neither GM nor player can call for a retest unless those conditions change."
This leaves Tru-leigh free to tackle the next obstacle: Joachim is in Jabal's tower, and so Tru-leigh has to get in there. The PCs are free to try and sneak into the tower without Halika getting in their way, and choose to go via the catacombs. I remember commenting on this at the time: Jobe's player made the test, on a low skill rank, but wanting to advance his Catacombs-wise. The test fails, and because of the failed roll after having taken the +1D bonus for working carefully, it fails in a way that makes the time spent on the effort backfire (as per p 29 of the rulebook): "If the player fails a test in which he is working carefully, the result indicates he has run out of time - the bomb goes off, the guards burst in, the old man dies, etc. By working carefully, the player is allowing the GM to introduce a serious complication upon failure."
To me as GM, the obvious time-sensitive aspect of the situation is Halika's drugged state; and a failure while working carefully is just the sort of
change in conditions that cancels "Let it Ride". Therefore, I decide to bring Halika back onto the scene, having wakened from her drugged state. But see how I bring Halika back into the action: I use her to negate the players' intent (which is mandatory for a failed task) - the PCs are not in the tower unobserved, but rather are observed by Halika, through the grate. This also correlates the consequence of the failure with the PCs' own knowledge - they can see that Halika is awake, as they look at one another through the grate.
This also sets up a new obstacle that Tru-leigh has to overcome, in pursuit of his Belief - it's a race to see who can get to the tower first. Halika wins, and so is able to kill Joachim. And then I use that to frame the next scene, that's already been discussed at length: Tru-leigh is there, in the room with Joachim, but Joachim's blood is spilling onto the floor.
The whole way through play, all the players have to do is
say what their PCs do. The fiction is consistent, the setting as realistic as any fantasy setting. In deciding how to narrate failure, and how to frame the scenes as they unfold, I'm treating plausibility as a consideration: the thing that goes wrong when sneaking through catacombs is that
you get lost; when you spend a lot of time lost in the catacombs, this can mean that your drugged victim wakes up (I just saw this happening in a movie I watched, Mission Impossible: Dead Reckoning); when you then have to race through the catacombs hoping to beat an assassin to the tower, she might get there first and kill the person you're trying to get to.
But plausibility is not the only consideration. The PCs
see the awakened Halika, and so can race her. The PCs lose the race, but get there just in time to see the aftermath of the decapitation. And so on.
