irESA to UC : 6 Managed migration questions

Hi - i've done a search and noted it seems ok to request several questions on a specific guide. If not let me know.

This is for long term sick (30 yrs+) , support group, irESA to UC : Managed migration notice dated 6-3-25

1. When does the 1 month assessment period start ? Is it the moment you create a UC account ? or the moment you start your UC application ? or the moment you click submit and send your UC application in ?
2. On submitting evidence: I'm confused re: pros/cons of submitting updated medical evidence, given my ESA hasn't been re-assessed since 2019. What's a good rule of thumb, where the managed migration UC application form doesn't ask for evidence ? On one hand i don't want to trigger re-assessment. On the other, my treatment/condition remains the same level. It would be just more recent medical paper-work. Would submitting it help in any way or is it redundant ?
3. In the income and earnings to do list section , do i need to itemise permitted work incomes if they are within the work allowance limit ? (Typically it's non PAYE, under £100 bi-monthly and never enough to be subject to tax.) I don't want the system to get confused by thnking i'm itemising over the work allowance wages. There's no mention about how to treat the former.
4. At what stage specifically should i notify the social housing landlord and Council Tax that i have applied for UC ?
5. What are the grounds for requesting direct rent payment to social housing landlord ? It's not entirely clear how to approach this request.
6. My ESA has always stipulated support group placement successfully using evidence and argument due to substantial risk. How best to/where do i migrate this into the UC application ?
7. This question may be too early - but, using the info above, do current reforms suggest i will be placed in the LCWRA group and no longer be subject to any WCA, except for a CoC ? Would i also recieve the proposed extra top-up premium for those never able to work ?

cheers - appreciated. twzzz

thanks for answers above...

To clarifications to ask:
re: answer 3 - are you saying i need to itemise recent wages even where they are below the UC work allowance threshold in the uc migration application form ?
re: answer 6: 'substantial risk' - i was thinking this might be required to mention when requesting / arguing for direct rent payments to landlord and things like online or phone contact as prefs for online id verification over job centre/outdoor visits. If so, and if not would it help to upload medical docs which support such requests anyways ? Or has this kind of option set become normalised now ?

thanks again
