Resolution of Strategy card vs Res of it's Action's effects

(To the Rules Forum moderators: Hi , I know this is referencing some cards from Path of the Destroyer, but my questions are not really about these specific cards, but about general rules interactions. Thank you for reading.)

So, is there a difference between the resolution of playing a Strategy card, and the resolution of the action it generates? I really hope and think so, because it would make logical and rule-istic sense.

This relates to the cards Mountains of the Phoenix with Udo and/or Fu Leng's Guidance

Ok, specifics: I play the terrain, Mountains of the Phoenix, which trigger is Battle: Before this battle's resolution... destroy the chosen units. Udo - Maho Reaction: After the resolution of an action that destroyed etc... Fu Leng's Guidance - Reaction: After the resolution of an action that destroyed etc...

So, it makes sense that when I play a Strategy card, and it successfully enters play, that I successfully resolved the playing of the Strategy card itself. The action it generates however, does not resolve until it, well, it actually finishes resolving. Most of the time, both the playing of the Strategy card AND the Strategy card's effects resolve at the same time, but in a few cases, such as Terrains, the playing of the card and the card's effects do not resolve at the same time.

According to what I, and my playgroup, remember from Samurai Edition rulings, Mountains of the Phoenix would not trigger Udo's and Fu Leng's Guidance's effects, because when you play the terrain card, you "resolve" it then, even though the action's effects do not actually resolve until later. Without seeming to be rude to any of the hard working rules guys, this ruling truly does not make sense.

Another even more complicated interaction is with Isawa Fosuta. Open: Bow Fosuta... at the start of each turn, you may target a Personality and give him a -1F/-1C Curse token. Does his action ever actually resolve? Ever?

Thank you

edit: I just realized what might have lead to that SE ruling. The Rings. The Ring of Water, Ring of the Void and Ring of Air all reference the successful resolution of actions. There might be a delay in these cards entering play if the rules actually work the way they seem to work.

You seem to have misunderstood the specific meaning that some words have when you play L5R. Let me try to explain them.

A Strategy card does not "resolve", it is played to use one of its abilities; see Glossary, Play. An action's effects do not "resolve", they are activated and applied while the action itself resolves; see Glossary, Resolve.

Per Abilities and actions, when an action resolves, its effects are activated in order: immediate effects are applied, well... immediately; delayed effects are, well... delayed until their trigger is met.

The resolution of an action ends when its last effect is activated. For instance, the Battle action from Mountains of the Phoenix ends when its delayed effect is activated, before the next player can take a Battle action or pass, even if its effect will be actually applied before this battle's resolution. As a consequence, the destruction from this Terrain's effect will not allow to use any Reaction triggered after the resolution of an action (that destroyed something) because the action's resolution has already ended for some time.

Moreover in the context of L5R rules, the word "successful" describes an action whose effects produced one or more actual changes in the game state; for more information, see Successful in the glossary. As a consequence, a Terrain action can be unsuccessful even if its Strategy card entered play, as my esteemed colleague explained there. For example, if you play the Terrain thanks to Untested Scouts and the Defender plays Reinforce the Gates, the Terrain's action's effects do not happen so the action is not successful although the Terrain card entered play.
