Follow-up review of #280. Builds on it, so merge that first.

An invented citation

The comment on the fragility threshold said "Reactome's own user guide makes this point" about hits resting on few entities. It may well. I did not check before writing it, and could not check afterwards — the user guide here is a Chroma database, not text.

Withdrawn rather than left standing. What is actually true is now stated: five is chosen, taken from this feature's own spec using 2 of 3 as its example of what is not evidence, and setting it properly is a curator's judgement, not a programmer's.

An invented citation is worse than none, because it survives review precisely by looking like the thing that ends an argument.

The second attack found the design sound

A flag that fires on everything is as useless as one that never fires — and this one flagged 12 of 12 pathways on the four-identifier analysis I had been testing with, which is exactly what a useless flag looks like.

Against a hundred-gene analysis on beta it flags 0 of 12, with found counts of 13 to 67. So it discriminates: it fires where a hit really does rest on nothing, and stays quiet on ordinary inputs. Both ends are pinned by a test using those real shapes rather than invented ones.

All checks gated with set -e this time.
