bud panels duplicate-add guard: server-side already_present flag + client-side error Brief w. FYI flash highlight on the existing entry — for each of the three #id_bud_btn panels (My Buds / post-share / gatekeeper-invite), the JSON response from add_bud / share_post / invite_gamer now carries {already_present, recipient_display, recipient_user_id}; bud-btn.js branches on already_present → calls new Brief.showDuplicateBanner({display_name, target_selector}) instead of the normal onSuccess append; banner title reads @<username> is already present, NVM dismisses, FYI dismisses AND eases in the .bud-duplicate-flash class (color: var(--terUser); text-shadow: 0 0 .5em var(--ninUser); transition: 600ms) onto the existing element (.bud-entry .bud-name / .post-recipient[data-user-id=…] / .gate-slot.filled[data-user-id=…]); gatekeeper "already present" = recipient is either GateSlot.FILLED + gamer OR has TableSeat OR has a pending RoomInvite (highlight target only set when seated — pending invites have no visible slot); .post-recipient chips + .gate-slot.filled cells gain data-user-id so the FYI selector can find them; my_buds.html now loads note.js via the {% block scripts %} pattern (Brief module is required by the duplicate banner path); bonus: latent test_jasmine.py bug fixed — "0 failures" in result.text matched "10 failures" / "20 failures" / etc, silently passing up to 99 failed specs; replaced w. re.search(r"(?<!\d)0 failures\b", …) (caught my new red specs, would've caught any prior Jasmine regression); 18 new ITs + 10 new Jasmine specs + 3 new FTs (one per panel) — TDD
