P15-057 Stage0 Decision

Status: GO; B17 is complete.

The B17 fixture gate contains 25 reproducible EROFS images and independently freezes all legal results and damaged positive FreeBSD errnos. The source commit 433cf4ec66478b65b291ec5b21a0bf6d806bd14f preserves the raw xattr filter feature declaration, saves its reserved byte, and gates the current filter format only at the ACL use site. Reserved values 0, 1, and 255 and feature present/absent combinations pass host and minimal FreeBSD 15 QEMU replay.

Evidence is in planning/pre15/evidence/20260814T203439Z-B17/. This decision does not authorize the separate cache, Bloom, or ordering batches.
