+
+Fullbleed 2.5.15 fixes the overlapping source slices in the fixture above.
+In a complete corpus run of source commit `9ec4f71`, before the version bump,
+that fixture changed from FAIL to PASS: **1,617 PASS, 26 FAIL and 19
+REFERENCE-DISPUTED**. Its above-floor page difference fell from 4.30% to 0.24%.
+The other 1,661 PDFs were byte-identical to the published 2.5.14 baseline;
+there were no new failures or lost passes. The unchanged upstream gate still failed.
+
+The source candidate's wheel reports 2.5.14; its commit and wheel hash distinguish
+it from the published package. This is not a complete corpus run of the final
+2.5.15 registry wheel. Fresh public Python and Rust installations passed 21 focused
+border-image cases, with Rust's `svg_raster` feature enabled to match the Python
+wheel. The original failing input also matched the reviewed source
+pixels when the public 2.5.15 Python output was rendered with PDFium.
