# 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.
