Known gaps ও সমাধান — Phase 4–11
৫ নভেম্বর ২০২৬। বর্তমান bounded performance evaluation-এর Phase 11 ফল, register ও method দেখুন; Phase 10 ফল ও Phase 9 ফল retained। Active release-এর original gates Phase 8 register ও আগের Phase 4–7 register-এ। Phase 8 ফল, Phase 4 calibration, workflow/recovery/release contract ও operational guide দেখুন। Historical reports ও তাদের নিজস্ব scope retained; Phase11 overall promotion gate pass হয়নি।

Local release-এর শেষ গ্রহণযোগ্যতা VALIDATION.md ও Phase 8 register-এ। পরের bounded scope হতে পারে raw I/O/feed ও busy-host tail latency, wider/private camera corpus, overnight, reference-display HDR judgement, calibrated অন্যান্য hardware/codec, full external FATE, reproducible distribution ও upstream security refresh। এগুলো পরীক্ষিত presets-এর বাইরে। Install/update/rollback-এর পৃথক actual gate আছে।
