Parity backlog snapshot 2026-06-20 (j) — magic const regression, array_find_key, JIT cast/offset (#1492)

[PurHur]

North-star tracker: #1492 (commenting disabled at 2500+ comments — snapshot issue instead).

Architect run 2026-06-20 (j)

Docker php8.2 vs bin/vm.php probes; 7 new + 2 expanded implementation-ready issues. No implementation PRs.

Top gaps filed (claimable)

#	Category	Gap
#10242	language · IMPORTANT	__DIR__/__FILE__/__LINE__ — Expr_MagicScriptConst compile failure (regression re-#9848)
#10243	stdlib · IMPORTANT	array_find_key() binary closure — LogicException: Cannot convert string to numeric
#10244	php-in-PHP	Shrink JIT/CastHelper (~125 LOC) → VmCast PHP
#10245	php-in-PHP	Shrink JIT/StringOffsetHelper (~129 LOC) → VmStringOffset PHP
#10246	php-in-PHP	Shrink JIT/ArrayAccessHelper (~301 LOC) → VmArrayAccess PHP
#10247	php-in-PHP	Shrink JIT/LateStaticBindingHelper (~152 LOC) → VmLateStatic PHP
#10248	php-in-PHP	Shrink JIT/EvalHelper → VmEval PHP SSOT

Upgraded specs (2026-06-20 re-verify)

• Stdlib: enum_exists() — must be false before enum is declared (basic_functions.c) #5013 — enum_exists() before declare still true/true (should be false/true); fresh Docker repro
• Stdlib: str_repeat() negative $times must ValueError not empty string (ext/standard/string.c) #9559 — str_repeat(-1) now throws ValueError on master; narrowed to add compliance guard + close

Notes

• #9602 vsprintf('%d',[7]) green on master (inline array literal fixed); no new issue
• Magic const blocks MagicScriptConstVMTest and self-host path builtins — prioritize Language: __DIR__/__FILE__/__LINE__ — Expr_MagicScriptConst compile failure regression (re-#9848, Zend/zend_compile.c) #10242 over Regression: highlight_file()/highlight_string() __FILE__/__DIR__ args still fail compile — re-#9924/#9140 (Zend/zend_compile.c) #9973 alone

No implementation PRs this run.

Lane B worker handoff (2026-06-26) — #1492 commenting disabled.

Scanned open queue for issue_number % 3 == 1; no claimable batch this run.

Excluded: stdlib label, php-runtime/php-in-php, ext/* scope, parity snapshots as work units.

Lane B compiler items without stdlib label are stale on master:

• Stdlib: ReflectionClass::getName() — VM/JIT parity (ext/reflection/php_reflection.c) #4465 ReflectionClass::getName() — repro prints string(1) "C" ✅
• Stdlib: array_find / array_any / array_all / array_find_key — JIT/AOT Closure callbacks (ext/standard/array.c parity) #4009 array_find* JIT Closure — stdlib automation unclaimed (green on master)

Open lane-B stdlib-labeled items remain STD Lib automation (e.g. #9559 compliance guard only).

No PR opened; lane B needs new language/compiler issues filed without stdlib/ext/* scope.
