`test_game_kit_panel_shows_token_inventory` (a133a9c's polish-9 FT fix) was looking for `id_kit_earthman_deck` in the Game Kit applet. CI #340 surfaced that the selector wasn't rendering — same `TransactionTestCase` migration-seed flush trap documented in `feedback_transactiontestcase_flush.md`:
1. `LiveServerTestCase` derives from `TransactionTestCase` → DB flushed between tests → migration-seeded `DeckVariant(slug="earthman")` row vanishes.
2. `apps/lyric/models.py:537`'s `DeckVariant.objects.filter(slug="earthman").first()` returns None in the post_save signal → `unlocked_decks.add(earthman)` silently skipped.
3. Gameboard view passes `request.user.unlocked_decks.all()` as `deck_variants` → empty → applet partial falls through to `{% empty %}` `id_kit_card_deck` placeholder instead of the per-deck `id_kit_{{ deck.short_key }}_deck` element the FT expects.
Fix mirrors the 14+ other FTs already using this helper: call `_seed_earthman_sig_pile()` in `setUp` before `create_pre_authenticated_session` fires the signal. The helper is `get_or_create`-based + idempotent.
Selector itself was NOT renamed — `short_key = slug.split('-')[0]` still yields `"earthman"` from slug `"earthman"`, so `id_kit_earthman_deck` is correct.
Verified locally: the test runs green w. the seed call in place.
Pre-existing in `git status`, bundled per project commit-everything rule:
- `src/.coveragerc` — add `*/delete_stale_my_sea_draws.py` to coverage omit list (one-off management script doesn't need coverage measurement)
