# Domain inference table (docs/DESIGN.md §6 "Domain"). Used only when neither
# policy.json `domains` nor the branch's `domain.yml` names the session's domain.
#
# Score per top-level domain = ext_weight × (distinct session extensions in its `[[ext]]`
# rules) + stem_weight × (distinct session stems in its `[[stem]]` rules). The best domain
# wins when its score ≥ min_score and beats the runner-up by ≥ min_margin; otherwise the
# session has no domain. A second level (`web.frontend`) is added only by a `[[stem]]`
# rule whose stems hit. Stems are compared Porter-stemmed (`animation` = `anim`).
