This is my feedback:

i just only remmeber that:
- Topology, question are the same TS3 but faults is diffrent. i wasted time to check Q1, Q2.
i got 58%.

Diag: is the same

i used c4c solution, it look goods.

Q1.1: about isis level 2 in Yellow AS.

Q1.2: BGP confederation in Green AS.
delete AS1, reconfigure AS65035 and AS65046 as request

Segment is perfer LDP

Q1.4: MPLS TE auto configure
create ccess-list should permit all loopback interface in Green AS

Thanks for sharing your experience. Question 1.6, Input policy on interfaces facing core, do you remember this part correctly? As this doesn't make sense why would you need input interfaces from core?
Would you be able to share c4c solution or atleast question for config section?
