* Pass 1 — dedup by (file, line, rule_key) triplet. Survivor = highest
* catalogue severity; severity tie → prefer a reviewer-agent finding over an
* engine finding, then the conformance reviewer; carries
* raised_by provenance, concatenates other reviewers' attribution into detail,

* Pass 1 — dedup by (file, line, rule_key) triplet. The survivor is ranked by
* (1) the catalogue tier (`getRule(rule_key)?.severity`, else the finding's own
* severity; lower `severityRank` wins), (2) a reviewer-agent finding over an
* engine finding, (3) among findings of one kind the higher asserted severity,
* (4) the conformance reviewer, (5) first seen. It is written with the highest
* severity any finding in its group asserted, so dropping a duplicate never
* lowers the group (review bc7f4e23; plan 2026-10-11-files-backticks-trial4,
* ADR "Pass 1 survivor order and group severity"). Carries raised_by
* provenance, concatenates other reviewers' attribution into detail, and
