Vol. 15 — TOTEM. The booth screen, scoped.

One volume solely dedicated to the 75" portrait touchscreen at Booth 1907 — the trade term for the object is literally a touch totem. The 16-piece portrait pack built in July becomes the seed: absorbed whole, renumbered under the volume contract, gated like everything else in the library. This page is the hardware truth, the slate, the laws, and the decisions — so the build starts from signatures, not assumptions. Alternate names if TOTEM doesn't land: MONOLITH (the dark slab), LIGHTHOUSE (unstaffed by design).

01The screen we actually have — verified, not assumed

Two different machines are in play, and the purchase link buys the wrong one. The name in circulation — "Samsung WA75F 75" UHD 4K Touchscreen" — is the WA75F (2025 WAF series: Android 14 with Google Play, Chrome built in, 400 nit, 40-point IR touch, VESA 800×400, $2,750, currently out of stock at Samsung). The audiovideonation.com link in hand sells the WM75A (2021 Flip 3: Tizen, no app store, no kiosk mode, browser-via-shortcut only, ~350 nit before the glass, VESA 400×400, $2,795). The scope below works on either — but the stand order, cabling, and fallback plan all differ, so the model gets locked before anything else is bought.
Neither model officially supports portrait. Samsung's own datasheets say "Rotation: Landscape only" for both (WAF leaflet; Flip 3 brochure — only the 55" Flip class ever rotated). Portrait means physically rotating the panel and letting an external PC do the rotation and touch remap — it works in practice, but it is outside Samsung's supported envelope: warranty-deniable, thermally unqualified, and the manual separately caps recommended use at under 12 hours/day. This is an accept-and-mitigate signature, not a default.
DecisionThe call
Model lockConfirm what was actually ordered. If nothing is ordered yet: the WA75F (or any WAF-series unit from another reseller) is the better machine for this job — brighter, Chrome fallback path, 40-point touch. If procurement is still open, the honest alternative is a portrait-rated signage panel + IR touch overlay (e.g. Samsung QMC-class: 500 nit, 24/7-rated, portrait officially supported) — the only path with zero warranty asterisk.
Portrait ruling(a) Accept-and-mitigate — rotated panel, external PC handles rotation + touch binding, nightly power-off (the <12h/day clause), 30 mm rear clearance, no enclosed cabinetry, no direct light wash, third-party portrait floor stand rated 50+ kg at the correct VESA pattern (Samsung ships no stand for the WAF). (b) Swap to the portrait-rated signage panel above. (c) Fall back to landscape — which redesigns every piece; named only to be declined deliberately. Kevin signs a, b, or c.
Playback path
— decided
External mini-PC (NUC-class) over HDMI with USB touch-back, Chrome in kiosk mode pointed at a local static server (localhost, not file:// — file:// gives iframes opaque origins, which breaks the rotation shell and cross-day localStorage). PC autologin → kiosk autostart; panel Boot Source pinned to the PC input; BIOS restores power after an outage. Pull the plug, plug it back in, content returns with zero touches. This path is identical whichever panel shows up. The WA75F's built-in Chrome + kiosk app is the documented fallback only; the WM75A's Tizen browser is a dead end.
Offline lawZero network during show hours: radios off, every font embedded as WOFF2 (the pack's Google Fonts link dies in this volume), no external fetch anywhere, all OS updates applied then disabled before the truck, player timezone locked to America/New_York (the clock piece and every daypart depend on it).
Brightness truth400 nits in a bright convention hall means ambient light lifts the blacks — so peak-aisle hours get high-contrast, bold, high-brightness content regardless of palette, and the subtle dark particle/hairline pieces run in lounge and dwell hours. Booth lighting design keeps direct wash off the glass. Encoded in the rotation shell's dayparts, not left as advice.

02The slate — 8 collections · 32 pieces

Deliberately not the house 104-card shape: one screen with ~32 operating hours across four days cannot air 104 of anything. All 16 pack pieces are absorbed with exactly one home each — 9 as-is · 7 upgraded · 16 new builds — and the ambient + practical rotation completes a full cycle roughly hourly, so every piece airs dozens of times instead of padding a count.

03Laws of the volume

04Gates & open rulings

The standing library gates (register, copy/claims, no competitor content — a hard no on a public always-on screen) plus three born here: the frame-safety photo gate, the dead-end audit on every touch piece, and loop-seam render QA (headless capture of one full loop, frame N must equal frame 0). Two rulings block specific pieces, not the volume: the fernie face audit — pieces 10/13 drew fernie before the Vol. 9 character bible existed; the whole fernie collection is born SIGN-OFF until their faces diff clean against the eight canonical symbols — and one consolidated MOBILE/PORTAL ™ request to Adam, covering the four artifacts idling on that ruling, instead of four cards waiting separately.

05Production plan — and what Kevin decides now

Build order: rotation shell first (everything mounts inside it) → the cross-cutting font-embed sweep over all 16 existing pieces → the 7 upgrades → the 16 new builds, gates as they land → renders (2160×3840 stills + loop-seam video QA) → gallery + hub card + build report → a full-bundle dry run on the real panel before the truck — boot-to-content, portrait touch remap, power-cycle recovery, brightness under hot lights. Setup morning must not be first contact with the hardware. Procurement lines: mini-PC + HDMI/USB kit + spare cables; portrait-capable floor stand rated 50+ kg at the locked model's VESA pattern; show-services power (~400 W). Library deliverables: gallery under the card contract with SHIP/SIGN-OFF/INTERNAL chips, renders folder, this scope + a build report in scopes-and-reports, hub Vol. 15 card, SharePoint archive.

The four calls — DECIDED (Kevin, July 6):
1 · Model LOCKED: WA75F — Kevin confirmed the purchase is the WA75F (the Android 14 WAF-series unit). Stand/cabling plan follows: VESA 800×400, external mini-PC path unchanged.
2 · Portrait CONFIRMED — accept-and-mitigate: physically rotated panel, PC-side rotation + touch re-bind, nightly power-off, clearances per the mitigation list above.
3 · Name: TOTEM — in use.
4 · GO — build executed. Slate delta at build time: +1 HANDS ON piece (Kevin's "dare to touch" goad piece, three payoff variants: bloom / boot / order, switchable in show-config). The volume ships with a recommended rotation order baked into show-config.js.
