<p class="text-sm mb-3">The Immediate Action builder offers an action indicator (<code class="font-mono text-sm">81</code>/<code class="font-mono text-sm">82</code>), a structured proactive command builder (REFRESH, DISPLAY TEXT, PLAY TONE with auto-generated COMPREHENSION-TLV objects), or a freeform hex input.</p>

<p class="text-sm mb-2">Error recovery per TS 102 226 §5.2.1.3 — one of three forms:</p>
<ul class="text-sm list-disc pl-5 mb-2">
<li><strong>Action Type:</strong> Immediate (00), delayed (01), or conditional (02) execution</li>
<li><strong>Trigger Conditions:</strong> SW pattern matching (any error, specific SW, SW range, specific command fails)</li>
<li><strong>Recovery Action:</strong> Action Indicator (81 session indication / 82 early response) or Proactive Command (DISPLAY TEXT, PLAY TONE, REFRESH) to notify user or fallback</li>
<li><strong>Retry Count:</strong> Number of retry attempts before giving up (0=no retry)</li>
<li><strong>Proactive command:</strong> COMPREHENSION-TLV set with DISPLAY TEXT or PLAY TONE (only these two are allowed in an Error Action, TS 102 226 Table 5.9)</li>
