+Display all deaths across all legs of a genlocke in a single unified graveyard view.
+
+## Display
+- Accessible from the genlocke overview page
+- Shows all fainted Pokemon from every leg in one list
+- Each entry shows:
+  - Pokemon sprite, nickname, species
+  - Which leg/game it died in
+  - Death cause (if recorded)
+  - Level at death
+  - Whether it was a transferred Pokemon (part of a lineage) or caught fresh in that leg
+- Sortable/filterable by leg, species, level, etc.
+- Summary stats: total deaths, deaths per leg, deadliest leg
+
+## Backend
+- `GET /api/v1/genlockes/{id}/graveyard` — Return all fainted encounters across all legs of the genlocke
+- Aggregates encounters with status "fainted" from all runs belonging to the genlocke's legs
+
+## Frontend
+- Could be a tab on the genlocke overview page or a separate sub-page (`/genlockes/:id/graveyard`)
+- Reuse existing graveyard/encounter display components where possible
+
+## Checklist
+- [ ] Implement `GET /api/v1/genlockes/{id}/graveyard` — query all encounters with status "fainted" across all runs linked to the genlocke's legs, include leg/game context per entry
+- [ ] Add summary stats to the response: total deaths, deaths per leg, deadliest leg
+- [ ] Indicate whether each dead Pokemon was a transferred Pokemon or caught fresh (join with GenlockeTransfer)
+- [ ] Build the cumulative graveyard component: list of dead Pokemon with sprite, nickname, species, leg/game, death cause, level
+- [ ] Add sorting (by leg, level, species) and filtering (by leg/game)
+- [ ] Integrate as a tab on the genlocke overview page or as a sub-route
+- [ ] Reuse existing graveyard display components where applicable
