Document in the DoD that data-model structs (domain models, query row
types, DTOs/views) belong in a crate's models.rs rather than the file
that produces/consumes them, once used outside that function -
matching the existing crates/core/src/models.rs pattern. Component-
local structs (Props, Styles, context) are exempt.
Apply it to db: move RankedArticleRow out of articles.rs into a new
crates/db/src/models.rs.
Require unit tests for non-trivial logic project-wide (db query/filter
logic, non-passthrough server::services code), not just core's pure
functions, per feedback that the original scope was too narrow. Thin
passthrough wrappers stay exempt, and genuinely DB/network-bound cases
must be called out explicitly rather than silently skipped.

Codifies the quality bar already implicit in the CI gates and existing
code patterns (crate-boundary SRP, per-domain db modules, test comment
style) so it's explicit and reviewable rather than tribal knowledge.
