<p>Scope and intent:</p>
<ul>
<li>This helper is shared by <a href="fn.is_empty_and_conjunction.html" title="fn partition::utils::split::is_empty_and_conjunction"><code>is_empty_and_conjunction</code></a> and
<a href="fn.simplify_and_bounds.html" title="fn partition::utils::split::simplify_and_bounds"><code>simplify_and_bounds</code></a> so both paths interpret conjunction atoms the same
way.</li>
<li>It only handles conjunction-only expressions. If any <code>OR</code> is present, it
returns <code>None</code> and lets callers keep their conservative fallback behavior.</li>
</ul>
<p>Behavior:</p>
<ul>
<li>Tightest lower/upper bounds are recorded per column.</li>
<li><code>=</code> contributes both a lower and an upper bound at the same value.</li>
<li><code>!=</code> and non-range atoms are preserved in <code>passthrough</code> for callers that
need to rebuild the conjunction.</li>
<li><code>has_conflict</code> is set when atomic constraints already contradict each
other (for example <code>a = 1 AND a &lt;&gt; 1</code>).</li>
</ul>
<p>Notes:</p>
<ul>
<li>This helper is intentionally a bit more general than the current
<code>split_partition_expr</code> contract, which now only feeds range-only
conjunctions into the main split path.</li>
</ul>

<p>Scope and intent:</p>
<ul>
<li>This checker is intentionally conservative.</li>
<li>It only analyzes expressions that can be flattened into:
<code>atom1 AND atom2 AND ...</code></li>
<li>If any <code>OR</code> is present, it returns <code>false</code> (unknown / not handled here).</li>
</ul>
<p>Strategy:</p>
<ul>
<li>For each column, keep only the tightest lower bound (<code>&gt;</code> / <code>&gt;=</code>) and
tightest upper bound (<code>&lt;</code> / <code>&lt;=</code>).</li>
<li><code>=</code> is treated as both lower and upper bound at the same value.</li>
<li><code>!=</code> is tracked per column to catch direct conflicts with <code>=</code>.</li>
<li>After bounds are collected, the conjunction is empty iff for any column:
<ul>
<li>lower value is greater than upper value, or</li>
<li>lower value equals upper value but at least one bound is exclusive.</li>
</ul>
</li>
<li>For discrete domains (<code>Int*</code>, <code>UInt*</code>), adjacent open bounds with no
representable value in between are also treated as empty.</li>
</ul>
<p>Notes:</p>
<ul>
<li>This is still a conservative fast path focused on conjunction emptiness
detection for split degradation.</li>
<li><code>split_partition_expr</code> currently restricts its main path to range-only
conjunctions, but this helper remains slightly more general so shared
bound collection and direct conflict checks stay reusable.</li>
</ul>

<ul>
<li><code>left = R AND S</code></li>
<li><code>right = R AND NOT(S)</code></li>

(<code>Collider</code>, <code>simplify</code>, <code>PartitionChecker</code>) and degrades to no-split when an
