Problem

Pillar 1 quick readiness is green on tip (user_release_ready: yes), but ./script/release-readiness.sh --full --json → user_release_ready: no because examples-aot-smoke fails on 001-SimpleWeb with exit 139 (segfault) after c:main_after_init.

000-HelloWorld passes; capability-matrix and examples-web-smoke are green on the same tip.

Observed (2026-08-08, Docker ./script/docker-exec.sh, master @ d0b2bc4585):

examples-aot-smoke: 000-HelloWorld: ok
examples-aot-smoke: 001-SimpleWeb: binary exited 139
phpc: fatal signal (segfault) after c:main_after_init

Repro	Zend	AOT (this tip)
examples/001-SimpleWeb via examples-aot-smoke.sh	n/a (smoke harness)	exit 139 segfault

Gate	Status	Symptom
docker info	green	OK
php script/bootstrap-inventory.php --check	green	OK 7248/7248
./script/release-readiness.sh --json (quick)	green	user_release_ready: yes (369 fresh / 0 stale)
make bootstrap-selfhost-link	green (partial honesty)	OK /compiler/build/selfhost via Zend gen-0 fallback (#21855 stale native driver)
./script/release-readiness.sh --full --json	red	first fail: examples-aot-smoke
capability-matrix --check	green	1173 builtins
examples-web-smoke	green	OK
gen-0 provenance	stale (warn)	cc281e13c + 23 lowering commits; unverified-restamp — not this ticket

Repro

./script/docker-exec.sh -- bash -lc './script/examples-aot-smoke.sh'
# or narrow:
./script/docker-exec.sh -- bash -lc './phpc build -o /tmp/simpleweb examples/001-SimpleWeb && /tmp/simpleweb'

PHP implementation target

• AOT / CGI env init path for examples/001-SimpleWeb (QUERY_STRING / $_GET / request bootstrap) — fix the segfault, do not skip the smoke
• Prefer PHP lowering / lib/Web/ / JIT helpers over new C runtime

Done when

• ./script/examples-aot-smoke.sh green for 000–009 (including 001-SimpleWeb)
• ./script/release-readiness.sh --full --json → user_release_ready: yes on tip (other full gates already green this run)
• No restamp-only / smoke-skip “fix”

Parent roadmap: #78 · meta: #8739 (reopen on tag day)

Filed from Release review 2026-08-08 — DEFER on #78.

Confirmed sole --full fail on tip d0b2bc4585:

• quick user_release_ready: yes
• --full user_release_ready: no → this ticket
• capability-matrix + examples-web-smoke green same run

claim: PHP Runtime → PHP — starting this run

TRY_FIRST (this workspace, tip):

Gate	Status	Symptom
docker info	green	OK
make bootstrap-selfhost-link	partial (in flight)	Zend gen-0 fallback — stale native driver (#21855 / #28998 claimed elsewhere)
php script/bootstrap-inventory.php --check	pending	regenerating / drift note on host
./script/release-readiness.sh --json	pending	running

No open php-in-php / runtime-shrink implementable tickets (#19215 closed). Claiming this Pillar 2 release-blocker (prefers PHP lowering / lib/Web/ / JIT helpers — no new C).

Plan: reproduce 001-SimpleWeb AOT exit 139 after c:main_after_init, fix in PHP path, verify examples-aot-smoke + --full readiness.
