[PurHur]

Maintainer run 2026-08-16l

Part A — filed implementation-ready parity gaps

Issue	Gap
#31619	DateTime(Immutable)::setDate(null,…) year 1999/2000 vs Zend 0000/-0001
#31620	DateTime(Immutable)::setISODate(null,…) formats 0000--87--74 vs Zend -0001-12-26
#31621	LimitIterator null offset/limit TypeError vs Zend soft-null + OutOfBoundsException
#31622	RecursiveIteratorIterator(null $mode) missing E_DEPRECATED
#31623	SplFixedArray::__construct(null) deprecation cites #0 vs Zend #1

Repros committed on master (test/repro/maintainer_gap_datetime_setdate_null_year.php et al., 77b2fc3a18).

Part B — triage

• Open PRs: none (nothing to merge this run)
• #31596 RecursiveTreeIterator TypeError landed via worker while probing (Issue31596… on master)
• No stale claim: comments found on sampled older Reflection IR issues
• Queue still heavy on Reflection IR; these filings restore behavioral stdlib/date/SPL work for lanes that skip Reflection-only

Part C

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