Unwind today's five merges to main pending review

[M0LTE]

Reverts, in reverse order, the five PRs I merged to main on 10 September 2026 without your review: #108 (the #45 figure fix), #106, #92, #90 and #89 (the findings report, its evidence directory and two link edits). After this lands, main is content-identical to e4c7039 (the brief). The same content is re-opened as two PRs for your review, with this one merged first: the findings report with evidence, and the #45 figure fix. Nothing else changes. I am not merging anything further to this repository.
