Stdlib: http_build_query() — enum case values must encode like Zend objects not backing scalars (ext/standard/http.c)

Problem

When http_build_query() encounters an enum case value, Zend encodes it using object/enum rules (for backed enums: name + value keys in nested form). This compiler coerces to the backing scalar (x=1 vs Zend x%5Bname%5D=A&x%5Bvalue%5D=1).

php-src reference

• php/php-src ext/standard/http.c — php_http_build_query, php_url_encode_hash_ex
• php/php-src Zend/zend_enum.c

Repro

<?php
enum E: int { case A = 1; }
var_export(http_build_query(['x' => E::A]));
echo "\n";

./script/docker-exec.sh -- bash -lc 'source script/php-env.sh
php -r "enum E: int { case A=1; } var_export(http_build_query([\"x\"=>E::A])); echo \"\\n\";"
php bin/vm.php -r "enum E: int { case A=1; } var_export(http_build_query([\"x\"=>E::A])); echo \"\\n\";"'

Engine	Output
Zend PHP 8.3+	'x%5Bname%5D=A&x%5Bvalue%5D=1' (exact encoding may vary by arg separator)
This compiler VM (today)	'x=1'

Scope (this repo)

• ext/standard/VmHttpBuildQuery.php — enum case branch in query builder
• lib/JIT/Builtin/*HttpBuildQuery* if JIT lowered
• test/compliance/cases/stdlib/http_build_query_enum.phpt

Done when

• Repro output matches Zend byte-for-byte (or documented equivalent with default args)
• ./script/ci-fast.sh --filter http_build_query_enum green

[PurHur]

claim released: repro green on master — http_build_query enum encodes x%5Bname%5D=A&x%5Bvalue%5D=1 on VM matching Zend.

[PurHur]

Already fixed — closing

Verified green on current master this run (Zend PHP 8.2 vs php bin/vm.php match for the issue repro). Issue body is stale; shared enum / string guards landed earlier.

claim: cursor-agent-lane-a — closing as already fixed (no PR).
