 ## Sprint 175 Detection result scale and false-positive evidence review (2026-07-13)
 
 - Bounded Detection Lab table rendering with client-side 25/50/100-row pagination while preserving the complete persisted detection set for MapLibre and QA/QC.
+- Compacted source-tile cells to filenames while preserving full persisted paths in tooltips.
 - Added a strict read-only false-positive evidence audit with role-count drift checks, polygon validation, WGS84 geodesic areas, size buckets, AOI/class/tile summaries and combined review GeoJSON.
 - Audited the active seven-AOI portfolio: 5,568 false positives among 13,613 candidates, median geometry area 184.5 m2, and 25.8% below 100 m2; Turnhout, Herentals and Geel carry the largest review volumes.
 - Recorded that existing QA evidence has no per-detection confidence values; the audit reports zero confidence coverage and does not infer scores from the run threshold.

 - Added local 25/50/100-row pagination with a default of 50 rows, bounded page controls and automatic page-one reset after run/filter/result changes.

 - Detection Lab keeps the complete persisted detection collection available to the existing MapLibre overlay and QA/QC flows.
 - The results table renders 50 rows by default and provides 25/50/100 row sizes plus previous/next controls. This bounds DOM work for dense AOIs without discarding or resampling detections.
 - Selecting another run, changing a class/confidence filter or loading a new result collection resets the visible table to page one.
+- Source tiles display their filename for compact scanning while retaining the complete persisted path in a hover tooltip.
 - Pagination is intentionally client-side over the canonical persisted response; detection API contracts and GeoJSON output are unchanged.
