Since it's been a while since this happened IU, I thought I might try to work out the bonuses associated with the roll to better understand Sealing. Hazou first attemps a Calligraphy roll vs TN ???, his base Calligraphy is 24 effective 27 from IN. He gets +10 on both rolls from the 5 days of research and rest, if he's smart he'll go down the time ladder for his first attempt at scribing and get another +3 from his AB of 3. He'll probably also invoke an Aspect or two "Jiraiya's Sealing Notes" "Promising Sealing Student" "Kagome Checked My Work" and "Have To Look Good In Front of My Student" are probably valid choices.
Hazō, Calligraphy 27 + 10 (research bonus) + 3 (time-ladder) + ???s (Unknown Aspects) + 4dF = 40 + ???
TN ???
Hazou has seen Tunneler's Friend but never researched it, so only a slight or no veterancy bonus from that end. He hasn't researched implosion seals either. So little experience in seals that deal with air. He has researched UGLSPs though so there's that.
As a side note, the Known Seals page has Hazou recorded having researched Rocket Boot seals, which seems unlikely at best.
Now on to the research roll. Hazou's base sealing is 20, but with SSA it's effectively 42, he gets +10 for the research bonus, +2x AB = 10 for taking 5 minutes to infuse since that's that's two steps down the time ladder. If Harumitsu is assisting him he can spend a FP to contribute his AB to Hazou's roll, let's say he does because it's cute, +1 for Harumitsu.
Hazō, Sealing 42 + 10 (research bonus) + (10 time ladder) + 1 (Harumitsu's AB) +???s (Unknown Aspects) + 4dF = 63 + ???
TN ???
A quick note about FP here, Hazou burnt 8 FP to live later in the update, that means he can't really reroll or invoke Aspects on either roll without violating causality. On the other hand, he didn't need to burn about 7 of that 8 FP. So he could have used them without dying later and violating causality. Except! He should have had a minor Physical Consequence during the update from his sealing roll from SSA. He still passes his Alertness check with a 34, but his Resolve check should have a -2, so it looks like he didn't need to burn 5 of those FP. Good thing Hazou's not actually dead. Also I think he generates an FP from taking a Consequence? Is that how SSA works? I feel like I understand this less and not more
