The binder cleared the targeting word's party bit `0x8` (implicit target 35) and raid bit `0x4` (targets 57 and 61) only for the caster, so no group member ever bound these spells. Affected spells:
- Power Word: Shield;
- the Blessings of Protection, Salvation and Sacrifice;
- Amplify Magic, Dampen Magic, Divine Intervention;
- every Greater Blessing;
- Seal of Protection and Seal of Sacrifice.
With a party member selected, they fell back to you or raised a cursor whose click bound nothing.
**The reference.** `BindTarget 0x6e5b40`'s party arm (`6e5cad`-`6e5cec`) asks `0x606c20(caster, unit)` and then `CanAssist 0x6066f0`. Its raid arm (`6e5cf1`-`6e5d2f`) asks `0x606d20` and `CanAssist`. The two predicates differ only in their membership call:
- The unit itself answers true.
- Otherwise both units need `UNIT_FIELD_FLAGS & 0x8`.
- Each side's controlling player is `0x606170`: charmer, else creator, else itself, and it must be a player.
- Either controller being you makes the answer the other's membership, tried both ways round.
- Membership is `0x4e7f70` for `0x606c20`: you or one of the four party slots. It is `0x4918e0` for `0x606d20`: that, or a raid roster row (`0x4baee0`).
**Changes:**
- `spell/group_relation.rs` builds both predicates as `TargetRelations::in_party` and `in_group`, over one controller helper.
- `GroupRoster` holds the party slots and the raid roster, and is published from `GroupState` before the input pass. No cast or hover system reads `GroupState` itself, so there are no new schedule orders.
- The binder's party and raid arms clear their bits for an assistable group member.
- The world pick's party leg (`4806b8`) shares `in_party`.
**Tests:**
- `group_relation.rs` covers the roster and each predicate leg: both player-controlled, pets through their owner, and the mirror.
- `the_shipped_party_and_raid_spells_bind_a_party_member` runs 11 real `Spell.dbc` rows.
- `the_press_the_click_and_the_hover_bind_the_same_group_members` runs 8 candidates through the party and raid words on the press, `SpellTargetUnit` and `SpellCanTargetUnit`, fed through the real `GroupState` publish. The candidates are a party member, a raid-only member, a stranger, pets, a friendly creature, the other faction and yourself.
