PLI: return the 7-byte location object, bound every proactive chain

The PLI answer used the 5-byte form 13 05 <MCC/MNC> <LAC> with LAC 0000
and no Cell ID.  That is the *Network Rejection event download* form
(TS 31.111 8.19.1); a PLI location for GERAN is 7 bytes - MCC/MNC, LAC
and Cell ID.  A card applet that re-reads its location (the Alfa
MultiIMSI applet, after a *LOCI status change) treated it as empty and
re-requested PLI on every STATUS tick.

The default is now 13 07 00F110 0001 0001: PLMN 001/01 (the test
network), LAC 0001, Cell ID 0001.  _build_tr injects it after the
Result; the TR data is pinned by a test.

While verifying a live PLI, the manual /api/status-poll chain turned
out to be unbounded: it looped on the PLI storm while holding
_CARD_LOCK, so the request never returned and every card operation
waited.  _handle_proactive_chain's max_rounds now defaults to
_POLL_CHAIN_MAX (the background poll always passed it; the manual poll,
ENVELOPE, menu and TP chains did not), and the manual poll passes it
explicitly.  A card that re-queues a command can no longer wedge the
card lock from any call site.

Tests: the PLI default + the built TR, the default chain bound and the
manual-poll call pin.  1061 Python + 1069 frontend; sw cache simple-v477.

+
+### Added
+
+- **Load testing** for test scripts and suites.  `POST /api/test/run` takes an optional
+  `iterations` count (the PWA's **Iterations** field next to *Start* / *Run suite*): the
+  run repeats N times, successful iterations are discarded (only the iteration counter and
+  the timing are kept; the per-step log is not rendered or retained), and the first
+  iteration that ends in an **error** stops the loop and keeps that iteration's full
+  report.  A manual stop ends it after the current iteration, and a card session change
+  between iterations is an error (a swapped card is never run against another card's
+  script).  The SCP80 counter state is shared across iterations, so packets continue from
+  what the previous run consumed.  The run status gains a `load` block (`iteration`,
+  `done`, `failed_iteration`, `elapsed_ms`, `avg_ms`); the count is a run parameter, not
+  part of the stored script or suite.
+
+- The **stuck-card watchdog** for test runs.  A card that stops answering (no status
+  word, no driver error) used to leave the runner inside a blocking `SCardTransmit`
+  holding the card lock — *Stop* could not take effect, the presence monitor waited for
+  the lock and a load test hung in that iteration without explanation.  After 30 s
+  without runner progress (a bounded STATUS/drain loop beats once per attempt) the
+  watchdog marks the run `stuck`, records `the card stopped responding (step N, no
+  answer for N s)`, sets the stop flag and **tries** to cancel the blocked transmit by
+  disconnecting the PC/SC link on a background thread.  Where PC/SC can cancel it, the
+  step fails through the ordinary `on_fail` path and the run finalises as an **error**
+  (never `stopped`); where it cannot (pcsc-lite serializes the disconnect behind the
+  pending transmit), the status already names the step until the driver's own card
+  timeout returns.  The transport is marked stale once the disconnect returns, so the
+  next *Equip* rebuilds it.  The status gains `stuck`; the help EN/RU,
+  `docs/test-scripts.md` and `docs/api.md` describe the behaviour and the
+  background-disconnect caveat.
+
+### Fixed
+
+- The **PLI location answer** now uses the 7-byte PLI form (TS 31.111 8.19.1):
+  PLMN 001/01, LAC `0001`, Cell ID `0001`.  The former default was the 5-byte
+  *Network Rejection event* form (no Cell ID) with LAC `0000`; a card applet
+  that re-reads its location after a `*LOCI` status change (the Alfa MultiIMSI
+  applet) treated it as empty and re-requested PLI on every STATUS tick — the
+  PLI storm that slowed RAM Explore.  The TR data is now
+  `13 07 00F110 0001 0001`.
+- The **proactive chain is bounded on every call site**: `_handle_proactive_chain`'s
+  `max_rounds` defaults to `_POLL_CHAIN_MAX` (the background poll always passed it;
+  the manual STATUS poll and the ENVELOPE/menu/TP chains did not).  A card that
+  re-queues a command (the PLI storm) could keep the manual poll looping forever
+  while it held the card lock — `/api/status-poll` never returned and every card
+  request waited.  The manual poll also passes the bound explicitly.
+- The load-test loop closes properly on a raised runner error (it used to leave the run
+  `running` forever - the PWA polled a dead run and *Clear report* stayed refused), on a
+  card session change inside a suite iteration, and on a member that was stopped; a
+  warning in any iteration is reflected in the final status, `avg_ms` covers the attempted
+  iterations (the failing one included), and each suite iteration's `counters_before` is
+  read fresh from the preset store.
+
+## [3.36.0] — 2026-10-23
+
+### Added
+
+- The batch **"waiting for the next card"** state is now a deliberate cue: the status
+  modal shows a card-into-reader animation next to the prompt, a short chime sounds
+  **once per card** when the run enters the waiting phase (Web Audio — no audio asset;
+  edge-triggered in the 2 s poll, so it does not repeat), and while the tab is hidden the
+  title hints "Insert next card".  The speaker button next to the status mutes the chime
+  and the choice is remembered (`simple_ram_batch_sound`); the chime is unlocked by the
+  Start click (browser autoplay policy); reduced-motion users get the static card-above-
+  the-slot picture.  The card follows the app's SIM silhouette (`sim.svg`): a cut corner
+  at the top and the contact pad near the bottom edge, sliding behind the reader bar.
+
+### Changed
+
+- A **batch delete that finds the object already gone** is still a success — the goal is met
+  and the run continues — but it is no longer reported as a plain "OK": the attempt's verdict
+  reads **Already absent**, the delete run's counts separate real deletions from no-ops
+  (`Deleted: N · Already absent: M`), and the notice says the card was already absent.  The
+  counts gain an `already_absent` bucket (the attempt result is `already_absent`); a
+  reinstall's tolerated pre-delete is *not* affected — its outcome is still the install.
+- The READMEs link the project's news channel: [Telegram — @youeyeseesee](https://t.me/youeyeseesee).
+
+### Fixed
+
+- The prebuilt `style.css` had gone stale: a rebuild restored utility classes the UI
+  already used but the output lacked (e.g. `bg-blue-50` on the batch notice, `inline-flex`,
+  `mx-2`, `max-h-48`, `w-44`, `min-w-24`).

+## A card that stops answering
+
+pyscard's `SCardTransmit` is blocking and has no timeout: a card that stops
+answering (no status word, no driver error) would leave the runner inside the
+step while it holds the card lock - Stop could not take effect, the presence
+monitor would wait for the lock, and a load test would hang in that iteration.
+The runner's **watchdog** watches a progress heartbeat: after 30 s without one
+(a bounded STATUS/drain loop beats once per attempt, so a long poll is not
+mistaken for a stuck card) it marks the run `stuck`, sets the error
+`the card stopped responding (step N, no answer for N s)` and the stop flag,
+and **tries** to cancel the blocked transmit by disconnecting the PC/SC link
+on a background thread.  Where PC/SC can cancel it, the blocking call raises,
+the step fails through the ordinary path (`on_fail` applies) and the run
+finalises as an **error** - never as `stopped`, even though the stop flag
+ended the loop.  The disconnect runs in the background because pcsc-lite
+serializes it behind the pending transmit (both take the per-context lock), so
+on that stack the call returns only when the driver's own card timeout fires
+(libccid derives it from the card's ATR); the run is already flagged and the
+status names the step meanwhile.  The transport is marked stale once the
+disconnect returns, so the next **Equip** rebuilds the link.  A physical card
+removal is unaffected: the driver aborts the transmit and the presence monitor
+clears the card session.

As soon as the file is selected it is validated and its <strong>memory requirements are estimated</strong> in the form: the <strong>NVRAM requirement</strong> (the code image + persistent data, the GlobalPlatform Card Spec C6+C8 style total) and the RAM estimate. The same box reports the <strong>libraries the CAP is linked against</strong> (its Import component: library name, AID and the minimum version <code class="font-mono text-sm">≥ x.y</code>, with standard names and families resolved and a Java Card SDK hint where known), the package/applet identity and the component breakdown (sizes and shares in load-file order) &mdash; grouped under the <strong>Package</strong>, <strong>Requires</strong>, <strong>Memory</strong> and <strong>Components</strong> headings.

+	<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&nbsp;409), and background STATUS polling and the automatic proactive handling are suspended &mdash; a command the card announces stays pending for the script, and both resume when the run ends. The card&rsquo;s own BIP commands (OPEN/SEND/RECEIVE/CLOSE CHANNEL, GET CHANNEL STATUS) are an exception: the terminal answers them for real &mdash; its channels keep working during the run and the BIP events flow for the channels the card itself opened (BIP <em>control</em> stays blocked) &mdash; unless the step&rsquo;s <code class="font-mono text-sm">respond</code> overrides the answer with <code class="font-mono text-sm">raw</code> TLVs or a non-ok result; 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 &mdash; 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).  A card that stops answering does not hang the run silently: after 30&nbsp;s without progress the watchdog marks the run as failed, naming the step, sets the stop flag and tries to cancel the blocked exchange by disconnecting the PC/SC link on a background thread (the link is marked stale, so the next <strong>Equip</strong> rebuilds it).  A driver with its own card timeout fails the step through the normal path instead.</p>
 	<p class="text-sm mb-2">The pill has <strong>four views</strong>: the <strong>suite list</strong> (default; <em>Add suite</em> / <em>Edit</em> / <em>Run</em> / <em>Export</em> / <em>Delete</em>), the <strong>suite editor</strong> (the suite's scripts in run order &mdash; the optional <em>setup</em> first and the <em>teardown</em> last, marked with role badges; per script <em>Run</em>/<em>Edit</em>/<em>Move</em>/<em>Copy</em>/<em>Delete</em>, the per-member <em>on failure</em> policy <em>stop</em> (default) / <em>continue</em>, and <em>ADM required</em>), the <strong>script editor</strong> (the step list; its <em>Start</em> runs that single script and shows the result under the steps &mdash; not preserved) and the <strong>suite report</strong> (after a suite run: every script's status, its step table with expected/actual, the failing note and a run-log excerpt; the summary with passed/warnings/failed/skipped, wall time, the SCP80 counters before&nbsp;&rarr;&nbsp;after per keyset, the preset and a card-session-changed warning; export as <em>JSON</em> or <em>Markdown</em>).  A <strong>suite run</strong> executes its scripts in order in <strong>one card session, without resets and without resume</strong>; <em>on failure</em> decides whether the suite stops at that script or runs the next one, the <strong>teardown always runs</strong> on a stop or a failure (while the card is in the reader) so the next test starts clean, and a card reset stops the suite and is flagged in the report.  <strong>Start with card reset</strong> resets the card and runs the full re-initialization before the suite starts (the scripts then run against a freshly initialized card); the preset must still match the card's ICCID afterwards and a required ADM is verified again for the new card session.  The initialization consumes the card's initial proactive commands, so a script cannot catch the first command after the reset (they stay in the proactive log).  <strong>ADM required</strong> (on the suite or a script) verifies the matched preset's ADM key <strong>once</strong> before the start &mdash; a failure refuses the run (verify manually with the ADM badge; nothing is retried automatically).  Scripts live in the suite's store (<code class="font-mono text-sm">~/.pysim-simple-server/test_suites.json</code>, <code class="font-mono text-sm">--test-suites</code>); every script belongs to exactly one suite, and a script can be moved or copied to another suite (a bundle export carries the suite plus its scripts; the old script-only export imports into an auto-created &ldquo;Imported scripts&rdquo; suite).</p>
+	<p class="text-sm mb-2">A run can be repeated: the <strong>Iterations</strong> field next to <em>Start</em> / <em>Run suite</em> runs the script or the whole suite that many times &mdash; a <strong>load test</strong>. Successful iterations are not tracked: the status shows only the counter (iteration k / N) and the timing, the per-step log stays empty, and memory use stays flat however high the count. The first iteration that ends in an error stops the loop and keeps its full report (steps, failed checks, run-log excerpt, suite member report); a manual <em>Stop</em> ends it after the current iteration, and a card change between iterations is reported as an error (the next card is never run against another card&rsquo;s script). The count is a run option &mdash; the saved script/suite is unchanged &mdash; and the SCP80 counters continue from what the previous iteration consumed.</p>

 		<li><strong>Actions</strong> &mdash; <em>Envelope</em> (Event Download: raw event type + data, with an optional source override &mdash; 82 terminal / 83 network) or <em>Event</em> (the semantic forms: the <strong>same form the Phone tab's send dialog uses</strong>, for every modelled event &mdash; the four events the server builds (Location status, Access technology change, Network rejection, Data connection status change) travel as fields it validates and builds at run time, every other event carries the form's built event-data hex (shown live under the form, with the one-ENVELOPE check); the device-identities source comes from the event (e.g. MT call &rarr; network) or its source field), <em>Menu Selection</em> (item id 1&ndash;255, or the item's text with an exact/contains match, case-insensitive by default &mdash; 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 &mdash; compact, or the TS 102 226 &sect;5.2.1 Command Scripting template <em>expanded</em> (AA) / <em>expanded AE&nbsp;80</em> around the C-APDU; the keys and the counter come from the card preset matched by the equipped card's ICCID &mdash; the run names the stored preset, so it always uses its keysets, TARs and counter &mdash; the server persists the consumed counter into it as the run proceeds), <em>STATUS</em> (with <em>attempts</em> &gt; 1 it polls until the card announces a command) and <em>Proactive drain</em> (poll STATUS and consume every announced command &mdash; the TERMINAL RESPONSE result for each, optionally a different result for the first; the attempt/interval bound; an optional <em>require</em> assertion over what was drained.  An empty poll passes, the final STATUS must be idle, and a still-pending command is handed to the next step &mdash; use it at the start, in the middle or at the end of a script to make sure the card has stopped sending; it also consumes a command a previous step left pending (a step that answered <code class="font-mono text-sm">91XX</code>). Every action has a response check: expected SW and data (exact, or a mask with <code class="font-mono text-sm">?</code> nibble wildcards &mdash; <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 &mdash; status / SW / data; the SEND SHORT MESSAGE transport works the same).</li>
 		<li><strong>Expectations</strong> &mdash; the card must have announced a proactive command in the previous step (SW <code class="font-mono text-sm">91XX</code>, TS 102 221 &sect;7.4.2.1 / TS 102 223 &sect;6.3); a <code class="font-mono text-sm">9000</code> means &ldquo;no command&rdquo;: the step fails at its fail level &mdash; Error stops the script, Warning continues (the tolerant &ldquo;consume a command if there is one&rdquo; form) &mdash; and a STATUS action with <em>attempts</em> &gt; 1 polls 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> &mdash; 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 &mdash; 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 &mdash; 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; a refused ENVELOPE (<code class="font-mono text-sm">62XX</code>/<code class="font-mono text-sm">63XX</code>) may carry no response packet at all &mdash; leave the PoR check at <em>any</em> or expect <em>no PoR</em> for such a step) 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> is part of the instruction: the <strong>result</strong> offers the full TS 102 223 &sect;8.12.0 list (each entry labelled <code class="font-mono text-sm">&lt;hex&gt; - &lt;alias or name&gt;</code>, plus a manual hex entry; with a command selected the list is grouped by the spec&rsquo;s applicability table (the command-relevant values first, the rest after &mdash; nothing is hidden); the aliases follow the spec &mdash; <code class="font-mono text-sm">ok</code> 00, <code class="font-mono text-sm">modified</code> 07, <code class="font-mono text-sm">cancel</code> 10, <code class="font-mono text-sm">timeout</code> 12, <code class="font-mono text-sm">refused</code> 22, <code class="font-mono text-sm">not_understood</code> 32, &hellip;), the <strong>additional information</strong> byte of the general result (default <code class="font-mono text-sm">00</code>; the &sect;8.12.2 terminal-problem values are suggested), the item identifier, the text (+DCS) and extra TLVs.</li>

+"""The test-runner stuck-card watchdog (v3.37.0).
+
+pyscard's SCardTransmit is blocking and has no timeout: a card that stops
+answering (no SW, no driver error) leaves the runner inside a step holding
+_CARD_LOCK, so Stop cannot take effect and a load test hangs in that iteration.
+The watchdog notices the missing runner progress, fails the run, and
+disconnects the PC/SC link - the pending transmit then raises and the normal
+step-failure path finalises the run.  The transport is marked stale so the next
+equip/operation rebuilds it.
