Game Sign picker @ /billboard/my-sign/ + billboard applet — Sprint 4a of My Sea roadmap — TDD

User scope (per design conv this session): split the room's sig-select responsibility off into a standalone billboard-context "My Significator" applet — branded "Game Sign" on the surface. Same 18-card pile as room sig-select (16 middle arcana + Major 0 & 1 filtered by Note unlocks); polarity collapses to a single FLIP choice (the FLIP btn in the picker carousel toggles User.significator_reversed). Selection persists globally on the User model + propagates to the billboard's Game Sign applet ; **naming convention locked**: "significator" stays at storage (User.significator FK + User.significator_reversed) + room sig-select context (DRY w. existing template/JS); "Sign" / "Game Sign" is the billboard-surface branding (file my_sign.html, URL /billboard/my-sign/, URL names my_sign + save_sign, applet name "Game Sign", page wordmark "Game Sign", btn label SAVE SIGN). Action URLs don't carry a trailing slash per project convention (/billboard/my-sign/save vs the page's /billboard/my-sign/) ; **schema**: User gains 2 fields — `significator: FK → epic.TarotCard (nullable, on_delete=SET_NULL)` + `significator_reversed: BooleanField(default=False)`. Migration lyric/0006_user_significator_user_significator_reversed.py auto-generated; reversible. Applet seed in applets/0009_seed_my_sig_applet.py adds the row (slug='my-sign', name='Game Sign', context='billboard', default_visible=True, grid_cols=4, grid_rows=6), idempotent update_or_create, reversible unseed() ; **picker page** (my_sign.html): solo lift of `_sig_select_overlay.html` — sig-stage-card scaffold + sig-stat-block + 18-card grid + SAVE SIGN form. Stripped: countdown / WebSocket / polarity / multi-user / reservations. Empty-state branch covers no-equipped-deck (link back to Game Kit; full Brief-redirect + Earthman-Backup fallback deferred to a follow-up sub-sprint). Minimal inline JS: click .sig-card → mark .sig-focused + set hidden card_id + enable SAVE SIGN; FLIP btn toggles .is-reversed + the hidden reversed input. Stage-card preview (name/qualifier population + keyword swap on FLIP) deferred — Sprint 4a follow-up will lift stage-card.js's populator into a non-room context ; **applet partial** (_applet-my-sign.html): renders user.significator's corner-rank + suit-icon + name_title if set; `.my-sign-applet-empty` "No sign chosen yet." otherwise. Header `<h2><a href="{% url 'billboard:my_sign' %}">Game Sign</a></h2>` links to the picker ; **helper refactor** (epic/models.py): extracted `_sig_unique_cards_for_deck(deck_variant)` from `_sig_unique_cards(room)`. New public `personal_sig_cards(user)` parallels `levity_sig_cards / gravity_sig_cards` but pulls from `user.equipped_deck` instead of `room.deck_variant`. Same Note-unlock filtering. No behavior change to existing room callers (3-line wrapper preserves the room signature) ; **TDD trail** — user called out mid-sprint that I'd skipped FTs; pivoted to FT-first. test_bill_my_sign.py (new, 3 FTs): T1 picker renders w. wordmark + target card present in grid; T2 click card → SAVE SIGN enables → POST persists → applet shows the card; T3 fresh user → applet renders empty-state. Initial reds — (a) setUp's `personal_sig_cards(user)` returned [] because StaticLiveServerTestCase → TransactionTestCase flushes migration-seeded DeckVariant + TarotCard between tests; fixed w. `serialized_rollback = True` on the test class (per [[feedback_transactiontestcase_flush]]); (b) h2 wordmark assertion against `MYSIGNIFICATOR` failed against the renamed "Game Sign" + the letter-splitter spreading chars across <span> children — switched to whitespace-stripped substring check `GAMESIGN`; (c) `.fan-corner-rank` text is CSS-hidden so Selenium returns "" — replaced corner-rank assertions w. data-card-id selectors (already-proven reliable from the parent .sig-card lookup) ; ITs (+12, in apps.billboard.tests.integrated.test_views): MySignViewTest (6 — login redirect, 200 + template, 16-card pile, save persists, invalid card_id → 403, GET save redirects); BillboardAppletMySignTest (3 — applet rendered, empty-state w/o sig, card+reversed class w. sig). PersonalSigCardsTest in apps.epic.tests.integrated.test_models (3 — happy path 16 cards, no-equipped-deck → [], schizo Note unlocks Major 1) ; pre-existing change picked up by the commit: my_sea.html branding "Game Sea" (user-modified mid-session; was "My Sea" in Sprint 3 — divergence captured in MEMORY.md follow-up) ; 1020 IT/UT green (+12) in 46s; 3 FTs green in 24s. Sprint 4a unblocks Sprint 4b (My Sea gating w. --terUser link to /billboard/my-sign/) + Sprint 4c (FT helper for mocking the sig choice across other FTs)
