Problem

Several ReflectionProperty methods diverge from Zend/php-src:

1. getRawValue / setRawValue — PHP 8.4 APIs (property hooks bypass). VM advertises them under default / PROFILE=8.2 where Zend 8.2 has neither. Prior closed add: Stdlib: ReflectionProperty::setRawValue()/getRawValue() — bypass hooks for init (PHP 8.4, ext/reflection/php_reflection.c) #6451.
2. getMangledName — not a php-src ReflectionProperty method on any current branch; VM invents it and returns the short name.
3. isDefaultValueAvailable — php-src puts this on ReflectionParameter, not ReflectionProperty (property side uses hasDefaultValue()). Prior related: Stdlib: ReflectionProperty::hasDefaultValue() / isDefaultValueAvailable() missing (ext/reflection/php_reflection.c) #11442 (hasDefaultValue). VM advertises the parameter API name on properties.

Verified 2026-07-23 (Zend 8.2.32 vs VM):

Repro	Zend 8.2	VM (default / 8.2 / 8.4)
method_exists(…, 'getRawValue')	0	1
method_exists(…, 'setRawValue')	0	1
method_exists(…, 'getMangledName')	0	1
method_exists(…, 'isDefaultValueAvailable')	0	1
method_exists(…, 'hasDefaultValue')	1	1 (ok)

On PROFILE=8.4, getRawValue/setRawValue may remain (php-src 8.4+); getMangledName and isDefaultValueAvailable must stay absent.

php-src reference

• php/php-src ext/reflection/php_reflection.stub.php — ReflectionProperty / ReflectionParameter method lists
• php/php-src ext/reflection/php_reflection.c — raw value handlers (8.4+)

PHP implementation target

• ext/reflection/ method table — remove getMangledName / isDefaultValueAvailable always; gate getRawValue/setRawValue on 8.4 profile
• Prefer PHP-in-PHP; no new runtime/*.c

Repro

./script/docker-exec.sh -- bash -lc 'PHP_COMPILER_PROFILE=8.2 php bin/vm.php test/repro/reflectionproperty_phantoms.php'
# compare: php test/repro/reflectionproperty_phantoms.php

Done when

• On default / PROFILE=8.2: getRawValue/setRawValue/getMangledName/isDefaultValueAvailable all method_exists false
• On any profile: getMangledName and isDefaultValueAvailable remain undefined on ReflectionProperty
• On PROFILE=8.4: getRawValue/setRawValue match php-src 8.4; hasDefaultValue unchanged
• Compliance guard; php-src-strict

claim: Lane C implementer — starting this run

Pillar 1 preflight (this host): release-readiness --json → user_release_ready: yes (inventory OK 6448/6448, north-star5-fast ok, vm-driver-probe ok). Claiming Pillar 4 ReflectionProperty phantom methods (#22601).

claim: Lane C implementer — continuing this run

Prior claim at 08:53Z has no branch/PR after ~1h. Pillar 1 now green after #22617 (user_release_ready: yes, inventory 6450/6450, north-star5-fast ok). Implementing ReflectionProperty phantom gates (same shape as #22599/#22616).

Merged #22624

Verification

• PHP_COMPILER_PROFILE=8.2 php bin/vm.php test/repro/reflectionproperty_phantoms.php → all phantoms 0, hasDefaultValue=1, call=undefined (matches Zend)
• PROFILE=8.4 → getRawValue/setRawValue = 1; phantoms stay 0
• Targeted VM/unit PHPUnit OK; north-star5-verify-fast OK after gen-0 fingerprint restamp
