Parity backlog snapshot 2026-06-19 (f) — closure __DIR__, autoload stack, ini_get_all compile, JIT array/scope (refs #1492)

[PurHur]

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

Maintainer run 2026-06-19 (f)

6 new implementation-ready issues from Docker php8.2 vs bin/vm.php probes; 2 thin issues expanded (#3343 ticks, #3693 money_format).

Top 5 gaps filed (claimable)

#	Category	Gap
#10181	language	__DIR__/__FILE__/__LINE__ in closures — compile fails Expr_MagicScriptConst (blocks PSR-4 autoload closures)
#10182	stdlib / bootstrap	spl_autoload_register() callbacks never run on class_exists() / new
#10187	stdlib / compiler	ini_get_all() — any call fails compile Unknown type encountered (blocks #9052)
#10183	php-in-PHP	Shrink JIT ArrayBuiltinHelper (~15k LOC) via VmArray PHP
#10184	php-in-PHP	Shrink JIT ScopeBuiltinHelper (~1.2k LOC) via VmScope PHP

Also filed: #10185 (BoundMethodCallableHelper FCC), #10186 (PropertyIsInitializedHelper isset).

Upgraded specs

• Stdlib: register_tick_function() / declare(ticks=N) — tick dispatch (ext/standard parity) #3343 — declare(ticks=N) + register_tick_function verified repro + compiler/VM scope table
• Stdlib: money_format() — locale currency formatting (ext/standard/formatted_print.c parity) #3693 — money_format() verified undefined-function repro + PHP 8.3 skip guard
• Stdlib: ini_get_all() — return shape and per-extension filtering parity #9052 — architect comment: compile blocker tracked in Compiler: ini_get_all() — any call fails compile Unknown type encountered (blocks #9052 runtime parity) #10187

Issue queue scan

• Scanned 500 open issues; 0 eligible in lane B after exclusions (stdlib, php-in-php, php-runtime, parity snapshots).
• All phase-2:language / area:compiler lane-B items are owned by other lanes (e.g. Language: builtin attribute classes phantom on 8.2 reference — Override/Deprecated/NoDiscard (Zend/zend_attributes.c) #11902 stdlib, php-in-php: JIT GcCollectCyclesRuntime — route gc_collect_cycles() through Vm GC PHP not ~1.3k-line LLVM (#1492) #9541/php-in-php: JIT ArrayBuiltinHelper — route array builtin LLVM through VmArray PHP not ~15k-line monolith (#1492) #10183 php-in-php, Stdlib: file_put_contents() named context: — compile error vs Zend success (ext/standard/file.c) #11575 stdlib compile-named-args).

No claims; no PRs this run.

[PurHur]

Follow-up: make bootstrap-selfhost-helloworld bootstrap-loop-probe finished (~35m).

• bootstrap-selfhost-helloworld → OK (Hello World)
• bootstrap-loop-probe → M0–M3 OK, gen-1→gen-2 OK, gen-2→gen-3 spine OK (3227/3230)
• Blocked (exit 2) at M4 full-revision argv probe: bin-compile-aot-inventory fails bin/compile.php lint (parseAndCompile returned null; message suggests stale gen-0 / rebuild via Zend — Self-host M4: full revision rebuild — native argv bin/compile.php compiles compiler tree #2880/Self-host M5: bootstrap-compile-invoke treats exit-0 driver run without output as failure (stale sync-back artifact) #3046)

Core link/helloworld gates green; M4 full-revision slice needs separate triage (likely prelinked gen-0 inventory argv driver drift on tar-copy docker-exec hosts).
