- archive the NATIVE stage-2 binary (/tmp/fpn_blaise2), not the QBE one
- COMPILER_ID drops -SNAPSHOT at release, re-gains it at the dev-cycle bump;
keep base version synced with project.xml or bif-coverage fails
- add fixpoint-warmcache.sh (WARMCACHE_FIXPOINT_OK) to the verification set
- rename the -pre bootstrap dir to the next cycle (not refresh-in-place)
- define the changelog/community-post range as <prev-tag>..v<X.Y.Z>
- note the CI STAGE1_TAG / rolling-bootstrap anchor bump
