Running it first would mean ``_verify_nonce``'s three distinct +refusals below could never actually surface through ``main()`` -- every +document that would trigger one of them already fails ``findings.validate`` +first, so the operator would only ever see the generic message and never the +category. Checking the nonce first makes the three refusals genuinely +observable end to end, which is what ADJUDICATION.md's "own reason, distinct +from the first" requirement means in practice. ``findings.validate`` still +runs -- second now, but still before a single finding reaches the judge loop, +which is STEP 3's actual guarantee, not "first" in an absolute sense. + +One exception: a document whose ``reports`` key is missing, non-list, or +empty defers straight to ``findings.validate`` instead of ``_verify_nonce`` +-- there is nothing for nonce verification to compare against, and calling +that "absent provenance" would bury ``findings.validate``'s more specific, +more useful message for exactly that shape defect.

It is called **once**, +after every finding has already been adjudicated (so it sees each finding's +final ``verdict``/``severity``, not the raw #117 input), and returns which +sets of ``finding_id`` s -- if any -- describe the same defect; it does +*not* choose the survivor itself. Survivor selection is ADJUDICATION.md's +own deterministic rule, applied here in ``_build_duplicate_groups`` / +``_survivor_sort_key``, and is the same code path regardless of which +dedupe mechanism decided the grouping -- the two are independent axes on +purpose, the same reason ``judge``'s per-finding verdict and STEP 6's +severity re-rating are independent fields on one return dict rather than one +combined decision. + +The alternative considered and set aside: folding dedupe into a single +richer ``Judge`` call/return shape.
