Maintainer run 2026-08-16g

Part A — filed (implementation-ready)

Issue	Gap
#31511	RegexIterator empty/null/invalid pattern constructs — Zend InvalidArgumentException
#31512	DirectoryIterator family null path — generic Path cannot be empty vs Zend Argument #1 ($directory)
#31513	Append/Limit/Caching null — TypeError cites IteratorIterator/Traversable vs Zend method+Iterator
#31514	SimpleXMLElement(null) TypeError — Zend Deprecated + Exception: String could not be parsed as XML

Repros (workspace): test/repro/maintainer_gap_regexiterator_empty_pattern.php, maintainer_gap_spl_dir_null_path_message.php, maintainer_gap_spl_iterator_null_inner_message.php, maintainer_gap_simplexml_null_data.php.

Part B — triage

• Open PR queue: empty (nothing to merge this run). Recent merges already landed (Stdlib: DirectoryIterator family missing path UnexpectedValueException (#31506) #31510 DirectoryIterator UnexpectedValueException, plus Reflection/stdlib workers).
• implementation-ready queue remains well stocked (Reflection backlog + today's behavioral IR).
• No stale claim: (>7d, no PR) found on sampled older IR issues; Regression: Collator::getSortKey Reflection (collator $coll, string $str) — Zend string $string → string|false; named string rejected (ext/intl/collator) #28785 has a same-day claim.

Part C

Not needed — IR queue non-empty after Part A.

Notes

• Distinct from closed Regression: DirectoryIterator/FilesystemIterator/RecursiveDirectoryIterator missing path RuntimeException — Zend UnexpectedValueException (ext/spl/spl_directory.c) #31506 (missing directory → UnexpectedValueException).
• Regression: AppendIterator/LimitIterator/CachingIterator null TypeError cites IteratorIterator — Zend method+Iterator (ext/spl/spl_iterators.c) #31513 same attribution class as open Regression: SplObjectStorage::offsetSet(null)/dim TypeError cites attach — Zend offsetSet (ext/spl/spl_observer.c) #31509.

[PurHur]

Closing as not_planned: status-only tickets (Maintainer status … / Worker lane … status …) are not work items. The IR queue already has 100+ implementation-ready issues — implement and merge rather than filing lane-status reports.
