riddle v0.1.0 — the enchanted diary

The enchanted diary from the demo — write with your pen, the page drinks your ink, and Tom writes back.

Prebuilt for the reMarkable Paper Pro (ferrari, aarch64, OS 3.26–3.27). No compiler needed.

Quick install (AppLoad)

1. New to this? First set up developer mode + AppLoad with remagic (one command).
2. Download riddle-appload-aarch64.zip below and unzip it.
3. Copy the riddle/ folder into your tablet:

   scp -O -r riddle root@10.11.99.1:/home/root/xovi/exthome/appload/

4. Add your API key (any OpenAI-compatible key — OpenAI, OpenRouter, …):

   ssh root@10.11.99.1
   cd /home/root/xovi/exthome/appload/riddle
   cp oracle.env.example oracle.env
   # edit oracle.env, put in RIDDLE_OPENAI_KEY=sk-...

5. Open AppLoad on the tablet, tap Reload, then tap The Diary. Write, and rest your pen.

Prefer to run your own pi setup instead of an API key? Leave oracle.env out — riddle falls back to pi. See the README.

⚠️ Runs as root and drives the e-ink engine directly. Tested only on Paper Pro. Keep SSH access as your escape hatch.
