Release blocker: helper-runtime prelink stale again (15 ext/dom units) — user_release_ready red

[PurHur]

Summary

./script/release-readiness.sh --json reports user_release_ready: no. First failing gate:

helper-runtime-prelink: FAIL
check-helper-runtime-prelink.php --strict
→ x86_64-linux — 244 fresh, 15 stale, 0 broken

All 15 stale units are under ext/dom/ (DomC14NJitHelper, DomLoad*, DomSave*, VmDomInstanceInvoke, …). Same class of defect as #24302 / #24336 (committed corpus skipped → cold compiles pay full emit).

Repro

./script/docker-exec.sh -- bash -lc 'php script/check-helper-runtime-prelink.php --strict'
# expect: N fresh, 0 stale, 0 broken

./script/release-readiness.sh --json
# expect: helper-runtime-prelink status ok; user_release_ready yes (other gates equal)

php-src / reference

N/A — compiler tooling / committed helper-object cache (prelinked/helper-runtime/), not Zend semantics.

Done when

• php script/emit-helper-runtime-object.php --prelink (Docker) refreshes stale units from live fingerprints
• php script/check-helper-runtime-prelink.php --strict → 0 stale
• ./script/release-readiness.sh --json → helper-runtime-prelink: ok (and user_release_ready: yes if no other gate fails)
• No restamp without rebuild — publish real unit objects (artifact honesty)

Gates: inventory OK 6614/6614; release-readiness red on helper-runtime-prelink (15 stale ext/dom units). Refreshing via emit-helper-runtime-object.php --prelink.

Duplicate of #24355 — fixed by #24357 (290 fresh, 0 stale; user_release_ready: yes). Closing.
