Report the sites the cutoff rejected, instead of nothing Running
Feedback from a reviewer: running INS and IAPP found no alternative reading frames, and they guessed the missing ribosome-profiling data was the reason. It is not. Scored down to 0.0005 on held-out folds, those two transcripts contain four sites in total -- the two annotated starts, an in-frame INS N-truncation at 0.0037 and an IAPP 3'UTR ORF at 0.0008. Nothing in another frame registers at all. The model looked and said no. The UI gave no way to tell those two stories apart, so every run now scores down to a floor of 0.0005 whatever cutoff is set, and the rejected sites are listed in their own tab with the best one quoted under the funnel. Same work for the model; an empty result now carries its own evidence. Adds IAPP as a fourth example (chr12, fold 3) and says plainly in the app and the README that a near-zero score is the model's prior, not a missing input.

Chain TIS prediction to epitope prediction end to end
Extends the Space from a single-model wrapper into the full pipeline the collaboration proposal describes: sequence -> TIS Transformer -> ORF typing -> MHCflurry -> candidate peptides All three stages are existing, openly-licensed tools. MHCflurry (Apache-2.0) is used rather than NetMHCpan, whose academic licence forbids redistribution and so cannot be hosted. Verified against the installed package rather than the docs, which were wrong in ways that mattered: - The FASTA-path CSV schema differs from the documented h5/GTF one. The score column is `output`, not `tis_transformer_score` -- so the previous tidy() matched no column and the cutoff slider and sorting silently did nothing. - TIS_pos is 1-based; everything here is 0-based. The conversion lives in one named function because an off-by-one shifts every reading frame and still yields a plausible protein. - Weights ship inside the wheel, so there is no download to warm. - --start_codons defaults to near-cognate (.*TG$…5278136
