docs: a refused envelope may carry no response packet (guide + help)
The alfa-dsa control-commands run showed the error case: an applet-level refusal (envelope 6200 for an unknown command) carries no PoR at all, so a por expectation on such a step can never match. The authoring guide's status-words section now states that a 62XX/63XX envelope does not guarantee a response packet - other warning paths still deliver one (the low-counter case arrives via SEND SHORT MESSAGE) - and that a step expected to be refused should leave por at its "any" default or assert "none"; help EN/RU notes the same. docs/test-scripts.md only, no code change; sw cache simple-v392 (help files are precached).

<p class="text-sm mb-2">A <strong>test script</strong> is an ordered list of <strong>actions</strong> and proactive-command <strong>expectations</strong> executed server-side on the equipped card. While a run is active the card belongs to the script: other card actions are refused (HTTP 409) and background STATUS polling is paused; the run report is kept in memory (also after reloading the page) until <strong>Clear report</strong>. Scripts live in the <strong>server-side store</strong> (<code class="font-mono text-sm">~/.pysim-simple-server/test_scripts.json</code>, <code class="font-mono text-sm">--test-scripts</code>), so every browser manages the same set; edits are written to the store as you change them (there is no Save button — a draft without a valid step stays local until it is valid); JSON export/import remains for backup and for moving scripts between benches (the old localStorage export imports as-is).</p>

<ul class="list-disc list-inside text-sm space-y-1 mb-3">

<li><strong>Actions</strong> — <em>Envelope</em> (Event Download: raw event type + data, with an optional source override — 82 terminal / 83 network) or <em>Event</em> (the semantic forms: Location status, Access technology change, Network rejection, Data connection status change — the fields are edited as a JSON object in the step editor, and the Phone tab's event form shows the built hex for the other events), <em>Menu Selection</em> (item id 1–255, or the item's text with an exact/contains match, case-insensitive by default — the step editor's <em>Match case</em> choice switches to an exact-case match; the text is resolved against the card's menu, which follows the applet's install parameters), <em>UPDATE/READ file</em> (path + mode; reads verify the file data), <em>raw APDU</em> (no auto-handler), <em>SCP80</em> (C-APDU or a pre-built secured packet, optional keyset number (kvn) / TAR / SPI1 / SPI2 overrides and a command format — compact, or the TS 102 226 §5.2.1 Command Scripting template <em>expanded</em> (AA) / <em>expanded AE 80</em> around the C-APDU; the keys and the counter come from the card preset matched by the equipped card's ICCID — the run names the stored preset, so it always uses its keysets, TARs and counter — and the counter is written back to it after the run) and <em>STATUS</em> (with <em>attempts</em> > 1 it polls until the card announces a command). Every action has a response check: expected SW and data (exact, or a mask with <code class="font-mono text-sm">?</code> nibble wildcards — <code class="font-mono text-sm">91??</code>) plus a PoR check for SCP80 (<em>any / no PoR / por_ok</em>, or a custom assertion of the decoded PoR — status / SW / data; the SEND SHORT MESSAGE transport works the same).</li>

<li><strong>Expectations</strong> — the card must have announced a proactive command in the previous step (SW <code class="font-mono text-sm">91XX</code>, TS 102 221 §7.4.2.1 / TS 102 223 §6.3); a <code class="font-mono text-sm">9000</code> means “no command” and is an error — add a STATUS action when the applet delivers on poll. The command type, qualifier and contents are verified: text / item / raw checks, an <em>Alpha</em> check (the command's Alpha identifier, tag <code class="font-mono text-sm">05</code>/<code class="font-mono text-sm">85</code> — distinct from the <code class="font-mono text-sm">8D</code> text string), an <em>SMS TPDU</em> check (the submit TPDU of a SEND SHORT MESSAGE: destination / PID / DCS / UDL / user data — for an applet's own SMS), a <em>PoR</em> check (a SEND SHORT MESSAGE carries the PoR when the packet requested PoR-in-submit, SPI2 bit <code class="font-mono text-sm">20</code>: the response status, the R-APDU SW and the response data; make sure an SCP80 step ran first — the R-APDU SW lives <em>inside</em> the response payload: an applet's own TAR returns application data, so check its data and leave the SW empty) and a <em>Files</em> check (the File List of a REFRESH, e.g. qualifier <code class="font-mono text-sm">00</code> = NAA initialization with full file change notification). The scripted <strong>TERMINAL RESPONSE</strong> (result, item identifier, text, extra TLVs) is part of the instruction.</li>

<li><strong>Fail levels</strong> — a mismatch flags the step as <em>Error</em> (terminates the script) or <em>Warning</em> (continues); each check is reported with expected vs actual values.</li>

<li><strong>Templates</strong> — Empty, <em>STK menu browsing</em>, <em>Applet via SCP80</em>; the step editor is form-based (the event action's fields are a JSON object) and individual scripts export/import as JSON.</li>
