Part A — Parity issues filed (4)

Language IR was drained (workers reporting no eligible claim; last language batch #31947–#31949 already closed). Filed four new implementation-ready VM/JIT gaps vs Zend 8.2.32 @ aa2e5e8b62:

• #31991 — $a["k"] += 1 / nested / .= / null-dim omit Undefined array key; ++ already warns after Language: $a[missing]++ omits Undefined array key Warning — Zend warns then treats as null (zend_execute.c) #30078
• #31992 — $obj->n++ with __get/__set emits Undefined property (value already matches); inverse of Language: $obj->x++ omits Undefined property E_WARNING — Zend deprecates + warns (re-#29195, zend_object_handlers.c) #29241
• #31993 — new Abstract / new Interface / new Trait catchable Error getLine() is 0; Zend cites the new line
• #31994 — keyed ["x" => $c] = … missing-key Warning cites the previous statement line

Repros: test/repro/maintainer_gap_assign_op_undef_key.php, maintainer_gap_magic_prop_inc.php, maintainer_gap_new_abstract_line.php, maintainer_gap_list_undef_key_line.php.

Part B — PR triage

• Open PR: #31962 (docs handover + AOT inventory). Not merged this run — docs-only; AOT probe claims were not re-run here.
• Open language implementation-ready queue was empty before this filing (stdlib queue is Reflection-stub / ext-owned; workers skip it).
• No worker PRs to merge. Did not unclaim: no stale language claims >7d without a PR.

Not verified

• No ci-local.sh / bootstrap link this run (issue filing only).
• JIT was probed for the four gaps (same mismatch as VM); AOT native not re-run.

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.
