Trust: DomCompareDocumentPosition spine gap + 27 stale helper-runtime — user_release_ready=no (re-#25887/#25892)

Foundation · Pillar 1 trust / spine-coverage + helper-runtime freshness (re-#25887 / re-#25892 / #24302)

Problem

./script/release-readiness.sh --json reports user_release_ready: no on master:

Gate	Status	Symptom
check-selfhost-spine-coverage-sync	fail	missing ext/dom/DomCompareDocumentPositionJitHelper.php, lib/JIT/Call/DomNodeCompareDocumentPosition.php
north-star5-verify --fast	fail	fails at spine-coverage step
check-helper-runtime-prelink.php --strict	fail	27 stale units (dom + class introspection helpers)
inventory / cold-build / vm-driver-probe	ok	OK 6647/6647; cold-build ok; probe ok

#25878 landed DomNodeCompareDocumentPosition / DomCompareDocumentPositionJitHelper but they were never added to test/selfhost/compiler_lib_spine_smoke/main.php. Helper-runtime fingerprints drifted after recent dom/introspection edits; cold checkouts skip stale units and re-emit live.

Repro

php script/check-selfhost-spine-coverage-sync.php
# actual: FAILED — 2 inventory files missing from spine
php script/check-helper-runtime-prelink.php --strict
# actual: 307 fresh, 27 stale, 0 broken
./script/release-readiness.sh --json
# user_release_ready: no

PHP implementation target

• test/selfhost/compiler_lib_spine_smoke/main.php — require_once for the two DomCompareDocumentPosition paths (via ./script/spine-sync.sh --no-link)
• prelinked/helper-runtime/x86_64-linux/ — re-emit stale units via php script/emit-helper-runtime-object.php --prelink (not fingerprint restamp)

Done when

• php script/check-selfhost-spine-coverage-sync.php OK
• php script/check-helper-runtime-prelink.php --strict → 0 stale
• make north-star5-verify-fast green (spine + related steps)
• release-readiness user_release_ready: yes (absent unrelated failures)
• No fingerprint restamp; real spine requires + real unit re-emit

claim: PHP Runtime → PHP — starting this run (Pillar 1 trust: spine DomCompareDocumentPosition + refresh 27 stale helper-runtime units)

Pre-claim gates:

Gate	Status	Symptom
bootstrap-inventory --check	green	OK 6647/6647 (doc drift warning only)
release-readiness --json	red	user_release_ready: no — first fail helper-runtime-prelink (27 stale); spine-coverage missing 2 DomCompareDocumentPosition paths; north-star5-fast red
vm-driver-probe	green	via release-readiness

Release manager verification (2026-07-31)

Independent probe on master @ 817c4d102 confirms this ticket:

Gate	Result
./script/release-readiness.sh --json	user_release_ready: no
helper-runtime-prelink --strict	27 stale (19 ext/dom/* + 8 class-introspection)
spine-coverage	missing DomCompareDocumentPositionJitHelper.php + DomNodeCompareDocumentPosition.php
north-star5-fast	fails via spine-coverage
inventory (readiness)	OK 6647/6647
cold-build / vm-driver / capability-matrix	ok

Labeled release-blocker. Pillar 1 P0 for v1.1.0 — see Release review on #78.

claim: compile/link trust automation — starting this run (Pillar 1)

Prior claim (~09:48Z) has no remote branch/PR after 40+ min; user_release_ready still no on master.

Pre-claim gates (this workspace):

Gate	Status	Symptom
bootstrap-inventory --check	green	OK 6647/6647
release-readiness --json	red	helper-runtime-prelink stale; spine missing DomCompareDocumentPosition paths; north-star5-fast red
cold-build / vm-driver-probe	green	via release-readiness

claim: compile/link trust automation — continuing (honest emit)

Pillar 1 still red on master. Open PR #25906 only rewrites helper-runtime manifest fingerprints (no unit.o/unit.bc changes) and omits InfoJitHelper — that is a restamp, not a refresh.

This run will re-emit stale units via php script/emit-helper-runtime-object.php --prelink (real objects) + keep spine DomCompare requires, then re-verify release-readiness.
