Correct the LP help text and document -lpl.
Line 217 ends with a stray } ("constraints and solutions}"). The parser accepts -lpl, --lp-permutation-limit at Lines 452-458, but printHelp does not list that option. Users cannot discover the permutation limit or its default of 128.

Push npsi_2 (the G-tagged copy) into the release union, not npsi.
The comment above the function defines the result as G(!psi) ∨ F(!psi ∧ !phi). The code creates npsi_2 with operator G and then never uses it. It pushes npsi instead, which has no G tag. The same npsi object is also the left child of conj. MergeCollection and UnionCollection both call reset()/merge() on that shared object, so their iteration states can interfere.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Replace the assignment operator_parent = LPOP::NONE with ==.
LPOP::NONE is 0, so the expression is always false and is_strict_next is always false. The assignment also overwrites operator_parent as a side effect. The strict parameter is currently unused in simplify_simple_quantifier<XCondition>, so the effect now is the clobbered state. The bug will take effect when strict is used.

Make compile_program idempotent; a second call fails the assert in debug builds.
apply_operator calls compile_program() for X and F. When a MergeCollection or UnionCollection has _operator == X, merge compiles buf.time_path and keeps it as the current timepoint. MergeCollection::satisfiableImpl then calls buf.compile_program() again at Line 586, and assert(!time_path->is_compiled) fails. X(a ∧ b) triggers this with nontrivial a and b. Release builds skip the assert and run the compile again, which does no harm.

Remove the unguarded empty path output.
MergeCollection::merge can advance an F timepoint, and MergeCollection::satisfiableImpl can apply the F context again to the empty current timepoint. This writes empty path to stdout without checking lpPrintLevel. The tool uses stdout for FORMULA and STATE_SPACE records, so this untagged line can pollute the output protocol.
A single empty SingleProgram stores an entry in final_lps; it is not itself the direct trigger.

Remove the unguarded stdout output from the empty-path branch in
MergeCollection::merge, while preserving its early return so protocol output
remains clean.
