You have presented yourself correctly with all your paperwork, and your are not allowed to fly through no fault of your own.
Article 2(i) (Definitions)
‘denied boarding’ means a refusal to carry passengers on a flight, although they have presented themselves for boarding under the conditions laid down in Article 3(2), except where there are reasonable grounds to deny them boarding, such as reasons of health, safety or security, or inadequate travel documentation
I'd imagine BA would go down the security route to deny a claim.
