The current finite rules, UI and original cozy block/footprint graphics were authored for KARUU. No upstream executable JS, jQuery/widget dependency, brand, sprite, audio, font or image texture is bundled. No hidden autoplay or player win API. Static release analysis of Blockrain performed earlier by coordinator is research evidence only, not a runtime pass for these games.

John's canonical five-expression Xiaoju source SHA d9a1a06db3e2a2d57970e7646af8afd9e098fa8f3bcd4dd19c67750ac713ba77; exact existing transparent atlas SHA 91fbc86e5a55e401c8be84fe8adf089f21368a66dac7bf738aea5dbe64d9126a. No regeneration or geometric/generic cat stand-in. Original KARUU music/effects and system fonts are reused; no external API, paid runtime service, account, tracking or telemetry. Original image/prompt/WAV/score and build-only encoder license remain in the source delivery.
