Regression: get_html_translation_table/hash_update*/ob_get_status named args rejected — Reflection OK or stream name drift (ext stubs)

Problem

Several builtins either (a) already match Zend Reflection but still reject named args (BuiltinParamNames gap), or (b) drift on stream-related param names. Probed 2026-07-27 vs host Zend 8.2.32.

Function	Zend Reflection	VM Reflection	Named symptom
get_html_translation_table	table,flags,encoding	same	Unknown named parameter $table
hash_update	context,data	same	Unknown named parameter $context
hash_update_file	context,filename,stream_context	context,filename (missing 3rd)	Zend stream_context: rejected
hash_update_stream	context,stream,length	context,handle,length	Zend stream: rejected
ob_get_status	full_status	same	Unknown named parameter $full_status

php-src reference

• php/php-src ext/standard/html.stub.php / basic_functions.stub.php — get_html_translation_table, ob_get_status
• php/php-src ext/hash/hash.stub.php — hash_update, hash_update_file, hash_update_stream
• Handlers: ext/standard/html.c, ext/standard/output.c, ext/hash/hash.c

PHP implementation target

• lib/BuiltinParamNames.php — add Zend stub maps for all five (include optional stream_context= / length= where stubs have them)
• Align hash_update_stream Reflection handle → stream; accept 3rd arg on hash_update_file
• Implementations stay in ext/standard / ext/hash PHP; no new C

Repro

./script/docker-exec.sh -- bash -lc 'php bin/vm.php test/repro/maintainer_gap_html_hash_ob_reflection_names.php'

<?php
try { var_export(get_html_translation_table(table: HTML_SPECIALCHARS)['"'] ?? null); echo "\n"; }
catch (Throwable $e) { echo get_class($e), ': ', $e->getMessage(), "\n"; }
try { hash_update(context: hash_init('sha1'), data: 'a'); echo "hash_ok\n"; }
catch (Throwable $e) { echo get_class($e), ': ', $e->getMessage(), "\n"; }
try { var_export(ob_get_status(full_status: false)); echo "\n"; }
catch (Throwable $e) { echo get_class($e), ': ', $e->getMessage(), "\n"; }

Done when

• All listed named forms succeed on VM (JIT/AOT when in scope)
• Reflection names match Zend (including hash_update_stream/hash_update_file arity)
• Compliance .phpt guard(s)
• php-src-strict; no php-compiler-strict shortcut

claim: Lane C implementer — starting this run

Trust snapshot (pre-claim):

• docker info: OK
• bootstrap-inventory: OK 6638/6638 (via release-readiness)
• release-readiness --json: user_release_ready=no; first fail spine-coverage (ext/soap/SoapHttpTransport.php missing from spine)
• north-star5-fast: red (same spine sync)
• vm-driver-execute-probe: ok
• Strategic alignment: compiler excellence pillars (2026 H2) #10533 comments locked at 2500+ — gate paste here instead

Lane note: only remaining lane-C IR not owned as ext/standard-only or a single named ext; fix target is lib/BuiltinParamNames.php (+ hash Reflection name/arity alignment per issue).

Merged #24963

Fix: BuiltinParamNames maps for hash_update_stream (stream/length= — InternalArgInfo still said handle), plus durable maps for hash_update, get_html_translation_table, ob_get_status.

Verification:

• php bin/vm.php test/repro/issue_23786_html_hash_ob_named.php matches Zend (stream_names=context,stream,length, digest 30f088…)
• PHPUnit testHtmlHashObNamedParamsResolve + VM/JIT named_args_hash_update_stream / named_args_html_ob_status OK
