The system's working memory.
L1 DB · L2 strategic ledger · L3 run-time rules. Every failure logged here feeds back into the next generation. No code changes between learning and applying.
T-glyph collapses to I — model ceiling on marketing_studio_image, confirmed across 4 generations.
Route wordmark-critical shots through gpt_image_2 explicitly. No amount of prompt strengthening fixes the T→I collapse.
Capsule sealing rim faint or absent on macro shots — needs explicit positive instruction.
When any capsule in frame: 'flared top edge has CLEARLY VISIBLE cream/off-white sealing rim, ~6–8% of capsule height.'
'MADE IN ELXOPE' rendered instead of 'MADE IN EUROPE' on heart icon — model hallucinates phonetic variants.
Small printed strings are locked. If a string can't render perfectly, OMIT entirely — never hallucinate adjacent characters.
T glyph collapses to I (NIRL) — per-glyph geometry rule needed.
T = vertical stem + horizontal top crossbar wider than stem — NEVER plain vertical column.
