?? "line ew quadratic embedding to k^n" ... ?? meaning of "embedding" in this context ??? ..... ???? ....

?? confusion about possibly contrasting kinds of "non-degeneracy" here ??? ....

?? anyway, interesting to omit embdding requirement too .... ??? ....

?? various ideas about "generic ..." / "quadratic ..." .... ???? ....

?? bit about clifford alg of free qfs on vsp .... ??? variants of this idea ?? ...

?? stuff here about .... ?? tierney / johnstone and "spectrum" (?? ...) and "higher genericity" .... ???? ......

(?? vague feeling about ... "generalized quantum double" here ... ??? ..... ???? ....)

?? space (?? ...) of quadratic forms on given vsp, vs moduli stack of qfs's .... ??? ....

?? stuff that we thought about recently in connection with baez's "walking composition algebra" stuff .... ???? .... cup / cap ... ?? partition into doublets on image complement ... ?? non-degeneracy .... ??? ....

?? quadratic map from k to k^n .... ?? vs vice versa .... ???? ...... homogeneous vs not ... ??? .....

?? l : line object ...

a : 1 -> 1
