Problem

PHP Runtime migration probe 2026-08-05 on master @ f9985ea88a: ./script/release-readiness.sh --json → user_release_ready: no.

First failing gate (helper-runtime is green — 363 fresh / 0 stale):

north-star5-verify: step 4f-m FAILED (gen-0 manifest/driver mismatch — #8713)

Fingerprint drift:

• manifest: 1d97d8ec16c1… (from honest refresh Trust: honest gen-0 argv refresh after #27697/#27698 lowering drift (#27696) #27701 / Foundation: north-star5-fast 4f-m gen-0 manifest/driver mismatch after #27693 (re-#27240/#8713) #27696)
• live: a022df86f99c…

gen0_provenance from readiness:

• driver last built: 85f848a02 (2026-08-05, Trust: honest gen-0 argv refresh — Foundation: north-star5-fast 4f-m gen-0 manifest/driver mismatch after #27693 (re-#27240/#8713) #27696 / Trust: honest gen-0 argv refresh after #27697/#27698 lowering drift (#27696) #27701)
• 1 lowering commit since (no manifest rewrite):
  • f9985ea88a — Language: Zend fatal for anonymous class in attribute ctor (Language: anonymous class in attribute ctor — wrong fatal (Zend/zend_compile.c constant expression) #27709 / Language: Zend fatal for anonymous class in attribute ctor (#27709) #27710)
• manifest_provenance: verified-fresh but driver bytes not rebuilt from current lowering sources
• functional smoke still ok (arith + echo) — mismatch is honesty/fingerprint, not "driver dead"
• Prior blockers Foundation: north-star5-fast 4f-m gen-0 manifest/driver mismatch after #27693 (re-#27240/#8713) #27696 / Foundation: north-star5-fast 4f-m gen-0 manifest/driver mismatch after #27230 (re-#8713) #27240 are closed; this is fresh drift past Trust: honest gen-0 argv refresh after #27697/#27698 lowering drift (#27696) #27701

Gate	Status
bootstrap-inventory	ok 7009/7009 (release-readiness; host --check may show committed-doc drift)
helper-runtime-prelink	ok (363 fresh, 0 stale, 0 broken)
cold-build	ok (~4s)
spine / root-readme / vm-driver-probe / gen0-functional	ok
north-star5-fast	FAIL — this issue (4f-m)

PHP implementation target

• Honest rebuild of committed prelinked/bootstrap-gen0/ driver (+ argv fingerprint) from current lowering sources in pinned Docker
• No restamp-only of .bootstrap_lowering_source.sha / manifest without a build that produced the artifact (artifact-honesty.mdc)

Repro

docker info >/dev/null
git rev-parse --short HEAD   # expect f9985ea88a (or tip with same 1-commit drift past 85f848a02)
./script/docker-exec.sh -- bash -lc 'make north-star5-verify-fast'
# step 4f-m FAILED (gen-0 manifest/driver mismatch — #8713)
./script/docker-exec.sh -- bash -lc './script/release-readiness.sh --json'
# user_release_ready: no; first fail north-star5-fast
php script/bootstrap-gen0-staleness.php
# stale — driver 85f848a02; 1 lowering commit since

Done when

• make north-star5-verify-fast → green (step 4f-m ok)
• ./script/release-readiness.sh --json → north-star5-fast ok; user_release_ready not blocked by this gate
• gen0_provenance.status is fresh (or warn-only with 0 lowering commits since driver build)
• Artifact rebuilt from sources — no fingerprint restamp without emit

claim: PHP Runtime → PHP — starting this run

Pillar 1 (pre-claim):

Gate	Status
bootstrap-inventory --check	ok via release-readiness 7009/7009 (host doc may drift)
release-readiness --json	user_release_ready: no — first fail north-star5-fast 4f-m
north-star5-verify --fast	FAIL step 4f-m (manifest 1d97d8ec… vs live a022df86…)
bootstrap-gen0-staleness.php	stale — driver 85f848a02; 1 lowering commit (#27710)
vm-driver-probe / gen0-functional / helper-runtime	ok

Honest make bootstrap-gen0-refresh-argv-driver (no restamp) — peer #27701 / #27696.

[PurHur]

Stopped exclusive full-spine launch — fingerprint-only drift (peer #27701) needs argv-only make bootstrap-gen0-refresh-argv-driver, not multi-hour Zend spine. Starting that path now.

claim: Auto (worker-lane-a) — continuing this run

Pillar 1 preflight on tip 77ba15049d:

• bootstrap-gen0-staleness.php: stale — driver 85f848a02; 6 lowering commits since (was 1 at issue open)
• No open PR for Foundation: north-star5-fast 4f-m gen-0 manifest/driver mismatch after #27710 (re-#27696/#8713) #27714; proceeding with honest make bootstrap-gen0-refresh-argv-driver (peer Trust: honest gen-0 argv refresh after #27697/#27698 lowering drift (#27696) #27701) — no restamp-only

[PurHur]

Lane A yield (this run): not claiming — PHP Runtime → PHP already has agent/runtime-php-gen0-4fm-27714 @ 5108cd9398 (argv refresh) with agent still pushing; prior lane-A claims stand down to avoid a duplicate exclusive refresh.

Master tip preflight @77ba15049d: inventory OK 7014/7014; gen-0 still stale (driver 85f848a02, 6 lowering commits since); release-readiness --json → user_release_ready: no (helper-runtime fingerprint + cold-build timeout + north-star5-fast 4f-m). Their branch tip is fresh vs f9985ea but needs rebase/refresh onto current master before 4f-m stays green.

No other lane-A implementation-ready + non-owned (stdlib / runtime-php / named ext) tickets; open language lane A = none. #10533 comments disabled (>2500) — status left here.

Verification

Gate	Result
check-bootstrap-gen0-manifest-sync.php	OK (a022df86f99c…)
bootstrap-gen0-staleness.php	fresh (lowering_commits_since: 0)
make north-star5-verify-fast	green (4f-m ok)
release-readiness --json	user_release_ready: yes, north-star5-fast: ok

Pillar 1 4f-m blocker cleared. No restamp — driver bytes rebuilt from sources (make bootstrap-gen0-refresh-argv-driver, provenance: verified-fresh).

Maintainer probe 2026-08-05 (77ba15049 master)

Confirmed pillar-1 red on current master before worker PR lands:

• ./script/release-readiness.sh --json → north-star5-fast fail (4f-m gen-0 manifest/driver mismatch)
• gen0_provenance: driver 85f848a02, 6 lowering commits since; manifest verified-fresh
• make bootstrap-selfhost-link: freshness refused stale build/bin-compile-aot; fell back to Zend gen-0

Open fix attempt: PR #27724 (currently CONFLICTING with master — needs rebase + re-verify). #10533 comments locked at 2500+.
