Parity backlog snapshot 2026-06-20 (t) — enum foreach byref, const new, hook isset, JIT SensitiveParam/EnumCases (refs #1492)

[PurHur]

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

Architect run 2026-06-20 (t)

5 new implementation-ready issues from host php vs bin/vm.php probes + JIT helper audit; 2 issues expanded (#4480, #4806). No implementation PRs.

Top 5 gaps filed (claimable)

#	Category	Gap
#10390	language	Regression: foreach by-ref enum cases → backing int not enum object (re-#10270)
#10391	language	Regression: class const new expression compiles/runs (re-#10312)
#10392	language	Property hook isset()/empty() must not invoke get hook
#10393	language	Property hook duplicate backing property name must fail compile
#10394	php-in-php	JIT SensitiveParamHelper → VmSensitiveParam PHP (#1492)

Also filed #10395 — JIT EnumCasesHelper → VmEnum PHP SSOT (pairs #10273).

Upgraded specs

• Stdlib: ReflectionClass::getMethods() — filter flags + inheritance/visibility parity (ext/reflection/php_reflection.c) #4480 — ReflectionClass::getMethods() filter matrix + IS_STATIC repro + diff commands
• Stdlib: ReflectionProperty::getHooks() / setHook() — PHP 8.4 property hooks reflection (ext/reflection/php_reflection.c) #4806 — ReflectionProperty::getHooks()/setHook() full repro + Language: property hook isset()/empty() must not invoke get hook (Zend/zend_property_hooks.c) #10392 cross-link

Verification notes

• Enum foreach by-ref: test/repro/maintainer_gap_foreach_byref_enum.php — Zend E/E, VM int/int
• Class const new: test/repro/maintainer_gap_new_in_constant.php — Zend compile error, VM int(1)
• Hook isset: test/repro/maintainer_gap_property_hook_isset_empty.php — VM prints spurious GET

No code changes this run.

Lane B worker run (2026-06-22) — no eligible compile/link issue to claim (refs #1492).

Scan (issue % 3 == 1, compile/link lane)

Excluded stdlib, php-in-php, parity-backlog umbrellas, and ext/* scope. No open PRs.

• Language: readonly class typed property defaults rejected at compile — valid since PHP 8.2 (Zend/zend_compile.c) #9841 CLOSED (invalid Zend parity)
• Child issues from snapshots (Regression: class const new expression compiles and runs — must match PHP 8.3 compile gate (re-#10312, Zend/zend_constants.c) #10391–php-in-php: JIT EnumCasesHelper — route Enum::cases() LLVM through VmEnum PHP not inline HashTable glue (#1492) #10395, Language: Generator return type without yield accepts scalar — missing TypeError (Zend/zend_generators.c) #10333) already merged/closed
• Remaining lane-B area:compiler items are stdlib-labeled or php-in-php JIT (other automations)

Bootstrap gates on this host

Gate	Result
make bootstrap-selfhost-link	OK (sidecar fallback)
make bootstrap-selfhost-helloworld	OK
make north-star5-verify-fast	OK
php script/bootstrap-inventory.php --check	FAIL — stale docs/bootstrap-inventory.md

Gen-0 driver still fails at c:main_before_php (sidecar recovery; documented M3 path).

Lane B compile backlog empty — need new implementation-ready language/compiler issues without stdlib/php-in-php labels.

[PurHur]

Lane B bootstrap fallback (2026-06-23): no claimable compile issues; fixed inventory blocker in NetworkServicesJitHelper.php — merged #10684 (blockers 1→0).

[PurHur]

Worker lane B note (2026-06-23): Audited open `implementation-ready` issues with `number % 3 == 1` (excluding stdlib-primary + php-in-php ownership). No lane-B language issue had a failing repro on master. Closed duplicate #10678 (property hook get-throw; already fixed via #10309/#9503). Recent lane-B queue is mostly stdlib (#10672, #10651, …) for STD Lib automation. Recommend bulk-close stale language regressions (#10284, #10288, #10390, #9922, …).

Worker lane B — queue audit (2026-06-23)

Automation: cursor-agent-lane-b (issue % 3 == 1; parent #1492 comment thread locked)

Scan method

• gh issue list --state open --label implementation-ready --limit 1000
• gh pr list --state open — 0 open PRs
• Lane filter: number % 3 == 1
• Excluded per worker rules: stdlib label, php-in-php/php-runtime/runtime-shrink labels, ext/standard/Stdlib: scope, parity snapshot trackers

Result

No eligible issue to claim this run.

Lane B has 324 open implementation-ready issues; breakdown:

• 122 labeled stdlib (STD Lib automation lane)
• 7 parity backlog snapshots (not implementable)
• 189 Stdlib: / phase-4:stdlib scope without stdlib label (still ext/* builtins — STD Lib lane)
• 6 remaining without excluded labels — all phase-4:stdlib regression probes (Regression: strnatcmp()/strnatcasecmp() — enum case operands coerce (re-#5733, string.c) #8776, Regression: dechex()/decbin()/decoct() — enum case operands coerce silently (re-#6018, math.c) #8782, Regression: DateTime::modify() — enum case modifier coerces not TypeError (re-#6132, php_date.c) #8785, Regression: str_split()/str_repeat() — enum case operands coerce silently (re-#5906, string.c) #8794, Regression: sort()/rsort() on enum arrays materializes backing scalars (re-#5691/#5546, ext/standard/array.c) #8905, Regression: ctype_*() — enum case operands return true not false (re-#8962, ext/standard/ctype.c) #8995)
• ~0 pure language/compiler issues without stdlib/php-in-php ownership

Spot-checks (already fixed on master, issues still open)

• Regression: foreach by-ref on enum cases materializes backing int not enum object (re-#10270, Zend/zend_execute.c) #10390 foreach by-ref enum: VM prints E/E ✅ (php bin/vm.php test/repro/maintainer_gap_foreach_byref_enum.php)
• Language: Closure::bind() must accept enum case as $newThis + enum case ::class pseudo (Zend/zend_closures.c, zend_constants.c) #10288 Closure::bind enum + ::class: claim released fixed ✅
• Regression: backed enum case local assignment materializes backing scalar — breaks ->name/->value (Zend/zend_enum.c) #9847, Regression: BackedEnum::from()/tryFrom() lookup broken — valid backing values NULL / ValueError (re-#3114, Zend/zend_enum.c) #9967, Regression: duplicate backed enum case values compile — re-#8687 (Zend/zend_enum.c) #10006: prior audits green on master ✅

Lane B blockers

Language/compiler gaps in lane B (#9730, #9847, #9922, #9952, #9967, #10006, #10390) carry stdlib label despite phase-2:language scope — worker lane B cannot claim per routing rules. Consider re-labeling or closing stale issues.

Next: STD Lib automation for ext/standard lane-B items; php-in-php automation for JIT helper issues (#9514, #9541, #9679, #10063, …).

Bootstrap gate

php script/bootstrap-inventory.php --check — stale doc (VmSerialize.php 36→37 methods); inventory regen needed on master, not a lane-B blocker.

Could not comment on #1492 (2500+ comments, commenting disabled). Logged here instead.
