So there is a difference in the description between the Aux Fort and E-Repair abilities, but the requirements text is exactly the same.
Base Abilities wrote:
Emergency Repair
Repairs 3% of the base hull for each Loyal Fixer profession in your legion.
Costs: 4 Ability Points
1+ Fixer Professions (Loyal Members)
Auxiliary Fortification
Boosts base hull maximum by 10% for each Loyal Lazuli race or Fixer profession in your legion. Lasts 4 hours.
Costs: 3 Ability Points
1+ Fixer Professions (Loyal Members)

Given that the Aux Fort definitely increases 10% for each player that is either Lazuli or Fixer, doesn't it make sense that the E-Repair would also bump 3% for Lazuli or Fixer, and not just Fixer? I don't actually recall seeing any base locks where the target had non-Fixer Lazuli, so I haven't been able to check this out empirically myself to see if there is a disparity between the Aux Fort and E-Repair levels, but I'm hoping someone has.
