Parity backlog snapshot 2026-06-20 (i) — is_a enum, enum const regression, JIT unset/foreach (refs #1492)

[PurHur]

Living snapshot for #1492 — architect run 2026-06-20 (i). (#1492 comment thread is locked at 2500+ comments.)

6 new issues + 2 upgraded specs. No implementation PRs.

Top 5 gaps filed (claimable)

Priority	Issue	Category	Gap
1	#10235	stdlib/language	is_subclass_of(E::A, UnitEnum::class) false + is_a() TypeError on int — enum case scalarized before builtin
2	#10236	language	Regression: enum E { public const X = 42; } → E::X still undefined (re-#6407)
3	#10237	language	public private(set) promoted ctor compiles + runs; Zend 8.4 compile-fatal
4	#10238	php-in-php	UnsetHelper ~274-line LLVM monolith → route through VM PHP
5	#10239	php-in-php	ObjectPropertyForeachHelper ~348-line LLVM → route foreach-over-object through VM PHP

Also: #10240 (IteratorProtocolHelper php-in-PHP).

Upgraded specs

• Stdlib: mb_convert_encoding / mb_detect_encoding (ext/mbstring parity) #3075 — mb_convert_encoding() / mb_detect_encoding() verified missing + scope/done-when
• Stdlib: register_tick_function() / unregister_tick_function() — tick callbacks (ext/standard/basic_functions.c parity) #3720 — register_tick_function() + declare(ticks=N) coordination with Stdlib: register_tick_function() / declare(ticks=N) — tick dispatch (ext/standard parity) #3343

Queue context

Recent array regressions (#10229–#10232) and enum/JIT php-in-PHP (#10200–#10204) remain high-priority alongside the above.

Lane C worker scan (2026-06-24) — refs #1492

Automation: cursor-agent-lane-c (#1492 thread locked at 2500+ comments)

Queue scan

• Open issues scanned: ~1000
• Lane C (n % 3 == 2) eligible (non-stdlib, non-php-in-php, implementation-ready): 0
• Open PRs: none

Exclusions

All lane-C backlog is stdlib/phase-4:stdlib (~80+ issues), php-in-php/runtime-shrink (~10 issues), or parity snapshot meta.

This run

• Bootstrap: JIT Analyzer StaticPropertyFetch — Unknown array write op blocks compiler_lib spine AOT #11340 bootstrap Analyzer fix already merged (Bootstrap: JIT Analyzer StaticPropertyFetch — fix Unknown array write op (#11340) #11342) before ship.
• VM probe: php bin/vm.php -r 'echo \"vm ok\n\";' OK on master.

Maintainer action

File or re-label language/compiler/bootstrap tickets on n % 3 == 2 without stdlib label. Unfiled bootstrap blocker: M4 gen-1 emit helper link failed (exit 2, mode=inventory compile_driver).

Maintainer note (not lane-C claimable)

php vendor/bin/phpunit --filter property_hook_isset reports 1 failure: language/property_hook_isset_empty.phpt expects no get-hook side effects, but VM matches property_hooks_isset_empty.phpt (#10680 — get hook invoked on initialized backing). Conflicting PHPTs; no open lane-C issue tracks the stale guard.
