+# SN100 Arcade — Paper design audit (Fable 5.1, 2026-09-08)
+
+**Marker:** **SN100_ARCADE_PAPER_READY**
+
+Design-only audit trail for the Cortex Subnet 100 marketing site drawn in Paper.
+This file records board ids, tokens, the Overmind measurements the system is
+based on, and the operator locks that were applied. It is not a product spec:
+product truth stays in [`../OVERVIEW.md`](../OVERVIEW.md),
+[`../external-miner/`](../external-miner/) and [`../SITE_API.md`](../SITE_API.md).
+Nothing in the design changes emission, scoring or consensus semantics.

+
+## Operator locks applied
+
+1. **Navbar** — Challenges (game-menu dropdown with arcade icons: joystick, cabinet,
+   bug, padlock for retired), Benchmarks, Docs, Status, centred orb, Whitepaper,
+   primary CTA **Start mining**. No "Install CTX" button label anywhere; the install
+   one-liner stays in body terminals.
+2. **Hero art** — generated pixel art with a transparent background, one dedicated
+   piece per route, next to the H1: Home cabinet, Proof trophy, Bounty bug in a
+   crosshair, Mine pickaxe and coins. Palette `#1F4945` / `#F0ECE1` / `#F6F5F1`
+   only. Assets: [`assets/`](./assets/) (`sn100-arcade-cabinet.png`,
+   `sn100-arcade-proof-trophy.png`, `sn100-arcade-bounty-bug.png`,
+   `sn100-arcade-mine-pickaxe.png`). Responsive boards mirror the art.
+3. **Emission copy** — every board writes emission as **% of emissions**
+   (Proof 80% of emissions, Bounty 20% of emissions). No raw protocol units or bare
+   split integers as the primary metric on any UI board (Website, Components,
+   Responsive, Design System usage rules).
+
+## Owner canon carried on the boards
+
+- Gateway `https://network.cortex.foundation`; routes `/`, `/proof`, `/bounty`,
+  `/mine`, `/docs`, `/status`.
+- Live challenges: Proof 80% of emissions, Bounty 20% of emissions, nothing else.
+- Interim burn to UID 0 shown on Home (HUD cell, honesty ledger, sample table) and
+  Status (burn banner, emission ledger). No payout, APY or TAO price promises.
+- InferenceOffer is the RLM judge only; miners BYOK Lium; one digest-pinned eval
+  image (`sha256:78b614a1…`).
+- `relearn*`, `design`, `prism` appear only as retired / locked / 404.
+- Sampled 2026-09-08 (label subject to change): Proof `can_score true`, topics
+  `dt-no-ib-v0`, `muon-vs-adamw-10m-v0`; Bounty `can_score false`,
+  `scoring_backend unconfigured`.

+
+The file is one coherent dark CRT system; there is no separate light mode board.
+
+## Known gaps
+
+- Mondwest, neueBit and Geist Pixel are not available in Paper; Handjet and
+  DotGothic16 stand in. Swap when licensed faces are provided.
+- Paper does not render `clip-path`; notched corners are drawn with 4px squares.
+- Hero PNGs are referenced by raw GitHub URL from this branch; repoint to the site
+  asset pipeline when the site is built.
