Parity backlog snapshot 2026-06-20 (m) — foreach enum byref, JIT enum/FCC/attribute/scalar-dim (refs #1492)

[PurHur]

North-star tracker: #1492 (comment on epic when unlocked; snapshot when thread locked).

Architect run 2026-06-20 (m)

5 new implementation-ready issues from Docker php vs bin/vm.php probes + JIT helper audit; 2 issues expanded (#9256, #9499). No implementation PRs.

Top 5 gaps filed (claimable)

#	Category	Gap
#10270	language	Regression: foreach by-ref enum cases → backing int not enum object (re-#10134)
#10273	php-in-php	BackedEnumFromJit ~514-line LLVM → VmEnum PHP SSOT
#10272	php-in-php	FromCallableHelper ~214-line LLVM → VmClosure PHP SSOT
#10274	php-in-php	AttributeNewInstanceHelper → VmReflection PHP SSOT
#10271	php-in-php	ScalarDimFetchHelper scalar dim warnings → compiled PHP helper

Upgraded specs

• php-in-php: JIT StringPhpinfoRuntime — route phpinfo()/phpcredits() through VmInfo PHP not __compiler_phpinfo LLVM (#1492) #9256 — phpinfo()/phpcredits() JIT php-in-PHP migration spec + repro
• php-in-php: JIT DateIntervalFormatRuntime — route date_interval_format() through VmDateInterval PHP not LLVM (#1492) #9499 — date_interval_format() JIT php-in-PHP migration spec + repro

Verification notes

• foreach by-ref enum: test/repro/maintainer_gap_foreach_byref_enum.php — Zend E/E, VM int/int
• enum from()/tryFrom() JIT drift: pairs open Language: BackedEnum::from() invalid value — ValueError not 'Method call on non-object' (Zend/zend_enum.c) #9889, Regression: BackedEnum::from()/tryFrom() lookup broken — valid backing values NULL / ValueError (re-#3114, Zend/zend_enum.c) #9967
