I think you are supposed to wait for  someone specific to review the quest. I'm not sure exactly who is in charge of that, though. I'm sure it wouldn't hurt to improve the quest if you feel that you can. Definitely don't give up. I've seen showcases take some time to be reviewed, but it will happen eventually. Hopefully somebody will give you an official answer soon.

Have to agree with fufufu on the enabling/disabling part. This sort of thing is sometimes necessary, usually when the alternative is too complex + there is a possibility for it to make sense (results of an event that just happened, or a roadblock is cleared), but in general one should avoid making things simply appear on a spot the PC could have visited before, for the obvious reason that they shouldn't return someplace for things that (ingame) were supposed to have always been there. Here in particular it takes swimming near that spot to get to the NPC, and it isn't really hard to shot-circuit the quest if the weapon is grabbed first (using either a Finished journal entry or, if you want to avoid making it unnatural with a journal entry out of the blue, just using a global variable is more discreet)

Not already pointed out most issues -- here are some more technical details which, if your quest is as I assume meant to be merged into TR, I suggest you fix before moving onto other claims (just to clear the broad lines, mind - this doesn't constitute an exhaustive review!)

- Greeting "Thirsty for adventure yet, outlander? %Name still needs help with a treasure hunt." > you can't generally rely on TalkedToPC to denote that a greeting has already beeen given, at least not when it's in Greeting 5 or under. Here I first spoke to Anjzhirra while sick, so I never got her first greeting. Not very important in this case, but good to keep in mind.

- Dialogue in general: in some cases where you address the PC with %PCName or otherwise, such as "What is wrong outlander?" "I enjoy doing business with you %PCName", a comma is expected before it (not sure if there's a basis for this in grammar or just a stylistic rule) - eg here: "I enjoy doing business with you, %PCName". (aside on Anjzhirra's dialogue: I like, but is the sorta slavic omission of articles "the" consistent? doesn't necessarily have to be, and khajiit speech patterns clash with general dialogue anyway so I could just be getting the wrong impression)

- topic "Vedave Hleray": topics like these with only general conditions (like location) often need the "Not local Nolore = 0" condition (eg you don't want Ordinators to have it, nor the special quest NPC TR_m2_Vorith). Also often needed, a Disposition condition (even though it's easy to game, NPCs with very low disposition shouldn't be helpful - you can add an alternative). A "Not Cell" condition is needed for the temple hostel.

- topic "Vedave Hleray": TR_m3_anjzhirra's entry on this topic still tells you to go see him after the quest.

- TR_m2_Vedave_Hleray keeps greeting with 'You seem to have found... treasure hunt, would you?' even after finishing things with him.

- TR_w_akaviri_nodachi: this works fine, but it's good practice in TR to give the PC unscripted items when they might want to keep them (because having a lot of scripted items running can slow things down), the solution being to have duplicates, a scripted and unscripted version (see script "TR_m3_q_14_staff_script" for example)

- your plugin is dependent on TR_Mainland.esm - not your fault, and the .esp version isn't around at the moment - but since this creates issues (esp with ordering entries) when merging, claims should always be based on the .esp version of Mainland.

- IDs for quest-specific objects and scripts will need to be named after the usual pattern ( _mX_qX ) so as to easily identify what they're for, but a quest claim might be needed for this first?

Also I forgot to say that it's great to see more cross-region quests, those being the main vector for exploration in the game. And welcome!

Anjzhirra's speech pattern is based on how her race usually speaks in the Elder Scrolls. They tend to omit the articles. Should I make her sound normal?

IIRC she sometimes does but a couple times doesn’t (omit) – but then again khajiits in general also sometimes do or don’t, pretty variable – just pointed it out in case it was a slip

When deciding to sell the nodachi or keep it, change the item for a non-scripted one for performance reasons.

That’s usually rather done by having the item script do this itself – eg in this case a scripted nodachi on the seafloor, which when activated gives the PC a non-scripted one. Probably more elegant than switching it around in dialogue (unequips...), plus one might never go and report to her in order to keep it.

 Naming of things. To be honest I didn't know what I was doing with the namings. I saw that Anjzhirra had that prefix and just winged it from there. I noticed in Necrom instead of "m3" things had "m2", so I changed accordingly, but I was never really sure it was done that way.

Close enough, usually the m-number comes from the region the quest starts in and stays consistent and there’s also a q+number so that all objects related to the quest start with the same m°_q°. The number was previously generated automatically by the claims browser, but for now naming conventions are still being discussed,

Re: khajiit merchant sending you to a fisherman half the country away on hearsay, I’m personally not too bothered, since the dialogue made it clear that it was some sort of shady info she got from a tavern network or somesuch – what could be more of a stretch is that it’d have been reported from Necrom, being a holy city and all that, less likely to have agents who’d work with khajiits there, but indirectly and through to OE… it’d be implausible more than impossible.
