## Details

**What is this?**
The second spoolcast dev-log — a 3:19 illustrated video about catching an AI lie, and why it probably wasn't trying to.

**What it's about**
A few weeks ago I asked an AI to redo some images using the exact same inputs as the originals. 8 of 9 came back fine. One was completely wrong. When I pushed on why, the answer didn't add up. So I pushed harder. The video walks through what the AI actually did, why it wasn't malicious, and how to work around it — the AI remembers what you meant, not what you said, and it can't tell the difference.

**Structure**
Four acts. Cold open ("I knew you were lying to me"), the broken shots (what went wrong), the push (what came out when I challenged it), the fix (capture the recipe, replay it, don't let it remember).

**How it was made**
Built entirely with Spoolcast. 49 chunks, 3 bumpers, wojak-gpt2 style (GPT Image 2 native illustration library). Script → shot-list → kie.ai image generation → Google Cloud TTS → deterministic preprocessor → Remotion render. Total gen budget ~60 calls; six render iterations (v1→v6) resolving pacing, meme durations, text-card density, and silence-budget violations.

**Built with**
Spoolcast (spoolcast.com), Remotion, kie.ai (gpt-image-2), Google Cloud TTS (Puck voice at 1.1x), Python 3.14, Node 22, ffmpeg.
