Shay a435411be5 feat(packs): en_core_relations_v2 — pronouns + role-fillers (Phase 2.4)
ADR-0065 P2.4.  Eight specialization lemmas, each a typed
specialization of an en_core_relations_v1 primitive:

  mother / father           is-a parent
  daughter / son            is-a child
  sister / brother          is-a sibling
  grandparent / grandchild  is-a ancestor / descendant (1-step)

Strict pack-internal taxonomy under kinship.*:

  mother      → kinship.parent.female
  father      → kinship.parent.male
  daughter    → kinship.child.female
  son         → kinship.child.male
  brother     → kinship.sibling.male
  sister      → kinship.sibling.female
  grandparent → kinship.ascendant.transitive_1step
  grandchild  → kinship.descendant.transitive_1step

  - SHA-256 checksum 7d0583f7e6a13ce72a5b0b191786cfc57af31583dc5111b24c3466e89ee70856
  - Orthogonal to en_core_relations_v1 + en_core_cognition_v1 (zero
    lemma collision in either direction)
  - Mounted by default in RuntimeConfig.input_packs + added to the
    cross-pack resolver's DEFAULT_RESOLVABLE_PACK_IDS

Companion corpus relations_chains_v2.jsonl seeds 7 v2-internal
reviewed chains so DEFINITION/CAUSE/VERIFICATION on every v2 lemma
grounds (not just DEFINITION via the pack path):

  cause_mother_precedes_daughter
  cause_father_precedes_son
  cause_grandparent_precedes_grandchild
  cause_daughter_follows_mother
  cause_son_follows_father
  verification_daughter_requires_mother
  verification_son_requires_father

Registered as a third TeachingCorpusSpec alongside cognition and
relations_v1.  Strict pack-internal: every chain's subject AND
object reside in en_core_relations_v2.  Cross-pack chain shapes
(e.g. v2 subject + v1 object) deferred per teaching_order.md §5.

Live verification:
  > What is mother?
    [pack] mother — pack-grounded (en_core_relations_v2):
    kinship.parent.female; kinship.parent; biology.maternal.
  > Why does mother exist?
    [teaching] mother — teaching-grounded (relations_chains_v2):
    mother precedes daughter (kinship.child.female).
  > Does daughter require mother?
    [teaching] daughter requires mother — verification-grounded.

10 pack-contract tests passed.  Curated lanes all green; cognition
eval byte-identical.
