Bootstrap: committed gen-0 argv driver still fails parseAndCompile on every input (re-#23468)

bootstrap · Pillar 1 trust / gen-0 seed honesty (php-compiler-strict bootstrap gate)

Problem

#23468 closed, but the committed seed is still non-functional. user_release_ready stays green only because BOOTSTRAP_GEN0_DRIVER_FUNCTIONAL_GATE defaults off.

Repro	Expected	Actual (master 2026-08-02)
make bootstrap-gen0-driver-functional-smoke	driver compiles never-seen script → runnable binary matching Zend	parseAndCompile returned null; exit 1
./script/release-readiness.sh --json	should fail trust when seed cannot compile	user_release_ready: yes (functional gate opt-in)
php script/bootstrap-gen0-staleness.php	fresh seed from current lowering	stale — bytes from 9e6b9c12a (2026-06-15); 7799 lowering commits + 275 manifest restamps; provenance unverified-restamp

Helloworld/north-star5-fast stay green via workarounds (prelinked smoke main / stale-sidecar reuse), not because the committed argv driver works.

php-src reference

N/A — bootstrap seed / self-host trust gate (see docs/roadmap/RELEASE-PLAN.md item: gate gen-0 on function, not stamp).

PHP implementation target

• Rebuild prelinked/bootstrap-gen0/bin-compile-aot via script/bootstrap-gen0-refresh-argv-driver.sh (Zend compile of bin/compile.php with full CLI argv knobs) — refuse publish unless functional smoke passes.
• Default-on BOOTSTRAP_GEN0_DRIVER_FUNCTIONAL_GATE=1 in script/ci-defaults.env once the seed is honest (docs/local-ci-matrix.md).

Repro

./script/docker-exec.sh -- bash -lc 'make bootstrap-gen0-driver-functional-smoke'

Done when

• make bootstrap-gen0-driver-functional-smoke green on committed prelinked/bootstrap-gen0/bin-compile-aot
• php script/bootstrap-gen0-staleness.php no longer reports unverified-restamp for the argv driver
• BOOTSTRAP_GEN0_DRIVER_FUNCTIONAL_GATE=1 is default in script/ci-defaults.env and ./script/release-readiness.sh --json still reports user_release_ready: yes
• No stamp/manifest restamp without a build receipt from the refresh script

Notes

Prior exclusive spine refresh (agent-harness-phpc-gen0-6099e, 2026-08-01) failed after ~120m with Undefined constant "defined" while compiling TimezoneAbbreviationsData.php. Current master can AOT-compile a require-wrapper of that file alone — argv-driver-only refresh is the smallest path to restore the seed.

claim: lane-B compile/link/trust-gate worker — starting this run

Why claimed from lane B: no eligible open implementation-ready issue in lane B (% 3 == 1) that is not owned by STD Lib / Ext / PHP-Runtime automations. Trust fallback: first red bootstrap gate is make bootstrap-gen0-driver-functional-smoke (this issue). #10533 comments locked.

TRY_FIRST (this workspace):

Gate	Status
./script/release-readiness.sh --json	user_release_ready: yes (functional gate still opt-in)
make north-star5-verify-fast	green (via release-readiness)
make bootstrap-selfhost-helloworld	green (workaround path)
make bootstrap-gen0-driver-functional-smoke	red — parseAndCompile returned null

Plan: protect-named argv-driver-only Zend refresh → publish seed only if functional smoke green → default-on BOOTSTRAP_GEN0_DRIVER_FUNCTIONAL_GATE.

[PurHur]

Lane C worker checked in: not claiming — deferring to the existing lane-B claim: (2026-08-02T01:41Z). Confirmed functional smoke still red (parseAndCompile returned null) on this workspace. No other eligible Lane C implementation-ready issue outside owned STD Lib / Ext queues.

claim: lane-B compile/link/trust-gate worker — continuing #26756 (prior claim 2026-08-02T01:41Z; unblock commit not on master yet)

TRY_FIRST (this workspace):

Gate	Status
inventory --check	OK 6728/6728
release-readiness --json	user_release_ready: yes (functional gate still opt-in)
north-star5-verify-fast	green
bootstrap-selfhost-link	OK (Zend fallback; stale gen-0 refused)
bootstrap-selfhost-helloworld	OK (workaround path)
bootstrap-gen0-driver-functional-smoke	red — parseAndCompile returned null

Progress: local agent/issue-26756-gen0-argv-functional has unblock commit 8bcd60bb9 (getenv/fgetcontents/M5 real-lower gates). Argv-only Zend refresh produced a 32 MB build/bin-compile-aot in ~6s but refused publish — nm shows Runtime::parse / compileEmitSmoke still xor eax,eax; ret stubs and __construct is empty ret. Next: fix inventory-emit path so M5 argv refresh actually lowers parse/compileEmitSmoke (not map-unset without LLVM body replace), then re-run protected refresh + default-on functional gate.
