Reverting variant_1 to its best-ever genome (76–88% APV over 28 videos). The last BIG_REWRITE added a meme pool + Gemini fallbacks but dropped retention to ~71%. We're stripping those four genes and restoring the strict context gate + sanitized captions that worked. Grok credits are exhausted so Gemini stays as the creative engine — the bet is the *prompt discipline* (not the model) drove the peak. Expect 75%+ APV within 10 videos; if ≤70%, we'll rewrite the Gemini prompts next cycle.
