release: date the 3.38.1 entry

A headless/SSH box can show a world-writable /run/pcscd/pcscd.comm
(srw-rw-rw- root root) and still be denied: pcscd enforces its PolicyKit
policy, whose defaults allow only active local sessions.  The startup
report, the start.sh pre-flight and the README troubleshooting now name
the exact rule (99-pcscd-allow.rules, org.debian.pcsc-lite.access_pcsc
and access_card) and explain why the socket mode does not matter.  The
pcscd-group instruction is gone: there may be no such group, and it is
not the gate.  The group route stays only as a note for a pcscd built
without PolicyKit.

Tests: tests/test_pcsc_startup.py asserts the polkit action IDs, the
rule filename and the 0666-socket explanation.

 ## [Unreleased]
 
+## [3.38.1] — 2026-10-25
+
+### Performance
+
+- **Equip/initialization reads no longer select the file twice.**  pySim's
+  `scc.read_binary`/`scc.read_record` call `select_path(ef)` first, but the
+  ICCID, network-state, EF.ARR and EF.PBR readers had already made a
+  parent-scoped selection and held its FCP.  A new `_read_selected_ef()` reads
+  the selected file directly — READ BINARY chunked at `max_cmd_len`, READ
+  RECORD at the FCP record length — removing one SELECT per file read and one
+  per record (~106 files + 94 records on the bench card: ~0.7 s of the ~3.4 s
+  traced startup init).  The pySim helpers stay as the fallback when the FCP
+  lacks the size/record length.
+- The startup TERMINAL PROFILE drain uses the chain's final SW, so an idle
+  chain no longer costs one extra STATUS poll (~128 ms).
+
+### Fixed
+
+- **A PC/SC access denial is reported instead of a silent serial fallback.**
+  When no reader was named and `readers()` failed (e.g. `SCARD_E_NO_ACCESS` —
+  the user may not use `pcscd`), the error was swallowed and pySim fell back to
+  the serial transport, failing on `/dev/ttyUSB0` while the server still printed
+  "listening".  The startup now probes PC/SC and reports **`PC/SC access
+  denied`** (naming the pcsc-lite PolicyKit actions and the
+  `99-pcscd-allow.rules` rule — a world-writable `pcscd.comm` does not bypass
+  polkit's active-session policy — plus the `pcsc_scan` cross-check),
+  **`pcscd is not running`** or **`no PC/SC reader found`**, then exits 2;
+  `start.sh` runs the same access pre-flight before launching.  An
+  explicit `-d <device>` keeps the serial path, and a reader present but no card
+  is still a normal cardless start.
+- **`setup.sh`/`setup.bat` recover from an incomplete `.venv`.**  A failed venv
+  creation (e.g. the Debian/Ubuntu `python3-venv` package missing) left the
+  directory behind; the next run saw `.venv` and skipped creation, then tried to
+  activate a venv without `activate`/`pip`.  The scripts now validate
+  `bin/activate`/`bin/python`/`bin/pip` (`Scripts\…` on Windows), remove an
+  incomplete directory and create it again; a creation failure removes the
+  partial directory and points at the venv package.  The READMEs note it.
+
+## [3.38.0] — 2026-10-24
+
+### Added
+
+- **Known-file picker in the test-script file actions.**  The `UPDATE file` /
+  `READ file` step editor's path field gains the selector the APDU builder's
+  SELECT rows use: the file-manager tree, the custom files and the standard
+  file list (`uicc_files.json`), grouped by root with a filter, filling the
+  path.  Only EFs are offered (the action reads/writes a file; a DF/ADF is not
+  a target); the text field stays authoritative, so a name path or a file the
+  lists do not carry can still be typed, and the picker preselects the current
+  path when it is known.
+- The **live load-test stats** now include the timing: while a script or suite
+  run repeats, the **run banner** (visible on every Test-script view), the
+  script editor's result head and the suite summary show the **elapsed time**,
+  the **average per completed iteration** and the **estimated time left**,
+  recomputed on every status poll (`testLoadTiming`/`testRunBannerText`; the
+  final report keeps the server's `elapsed_ms`/`avg_ms`).  No completed
+  iteration yet means no bogus average/estimate - only the elapsed time.
+
+### Changed
+
+- The load-test **iteration cap is raised to 1,000,000,000** (from 1,000,000) in
+  both layers: the PWA's `TEST_ITERATIONS_MAX` and the two field `max`
+  attributes, and the server's `_TEST_LOAD_MAX`.  The value is well inside the
+  JavaScript safe-integer range (2^53-1), so the counters and the progress
+  display stay exact; the practical ceiling is the run duration (at 50 ms per
+  iteration the cap is ~1.6 years).
+
+## [3.37.0] — 2026-10-23
+
+### 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.

 - **Smart card reader** (PC/SC or serial/FTDI) — PC/SC is preferable (`pcsc-lite` + `ccid` on Linux). `pyscard` has no Linux wheels, so it builds from source: install the PC/SC header package too (`libpcsclite-dev` on Debian/Ubuntu, `pcsc-lite-devel` on Fedora; on Arch `pcsclite` includes them).

 ### Troubleshooting
 
-- **"Failed to establish context: Access denied"** — `pcscd` isn't running or the user lacks permission: `sudo systemctl enable --now pcscd && sudo usermod -a -G pcscd $USER`.
-- **"device file /dev/ttyUSB0 does not exist"** — no serial reader; connect a USB reader or pass `-d` explicitly. The server still starts without a reader.
+- **"Failed to establish context: Access denied"** — the user may not use `pcscd`.  On a headless/SSH box the socket is often world-writable (`srw-rw-rw- root root`) yet access is still denied: pcscd checks **PolicyKit**, whose default policy allows only *active local* sessions (`allow_active=yes`, `allow_inactive=no`, `allow_any=no`).  Allow the user with `/etc/polkit-1/rules.d/99-pcscd-allow.rules` (replace `YOUR_USER`; any `*.rules` file name works):
+
+  ```js
+  polkit.addRule(function(action, subject) {
+      if ((action.id == "org.debian.pcsc-lite.access_pcsc" ||
+           action.id == "org.debian.pcsc-lite.access_card") &&
+          subject.user == "YOUR_USER") {
+          return polkit.Result.YES;
+      }
+  });
+  ```
+
+  then `sudo systemctl restart polkit` (or log out/in).  Start the service if needed (`sudo systemctl enable --now pcscd`); `start.sh` and the server report this and exit instead of falling back to a serial reader, and `pcsc_scan` shows the same error until the rule is active.  If your `pcscd` was built without PolicyKit and the socket is group-owned, adding the user to that group works instead.
+- **"device file /dev/ttyUSB0 does not exist"** — only with an explicit `-d <device>`: the device is not connected (or the path is wrong). Without `-d` the server no longer uses the serial transport.
+- **"no PC/SC reader found"** — connect a reader (`pcsc_scan` lists them) and restart; the server exits instead of starting without a reader.
 - **"Service not available" (0x8010001D) / reader gone after a `pcscd` restart** — the server recovers by itself: a watchdog revives pyscard's presence monitor and the next equip (automatic after re-insertion, or the **Equip** button) recreates the PC/SC transport (releasing the old link first). No server restart needed.
 - **"Card was removed" errors / auto-equip fails after a card swap** — a card insertion marks the PC/SC link for a rebuild (so the **first** attempt already uses a fresh link — on Windows the old one cannot connect after a swap), the auto-equip retries up to 3 times, and **every failed attempt rebuilds the transport** before the next one. A card removed while the server initializes at startup leaves it cardless with one line (no traceback), and the next insertion equips normally. The swallowed init error (with its traceback) is now printed as `AUTO-EQUIP: init output:`, and a card that is present but produced no card is a failure, not a silent "card gone". The watchdog re-arms with a doubling delay (5 s up to 60 s) while a card is present; a removed card clears the card state completely, so handlers answer "no card" instead of transmitting over the dead card.

+iteration counter and the timing are kept, so memory use stays flat.  The
+first iteration that ends in an error stops the loop and keeps its full
+report (steps, failed checks, log excerpt; for a suite, the member report);
+a manual stop ends it after the current iteration, and a card session change
+between iterations is an error.  The SCP80 counter state is shared across
+iterations, so packets continue from what the previous iteration consumed.
+The iteration count is a run parameter - the stored script/suite is unchanged.
+The accepted range is **1 to 1,000,000,000** (the PWA clamps, the server
+answers 400 above it).  While the run repeats, the run banner (visible on
+every Test-script view) and the result panels show the elapsed time, the
+average per completed iteration and the estimated time left, recomputed on
+every poll; the final report keeps the server's `elapsed_ms`/`avg_ms`.
+
+## 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.

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. The field accepts <strong>1 to 1,000,000,000</strong> iterations (the practical limit is the run duration). While it runs, the run banner (on every Test-script view) and the result panels also show the <strong>elapsed time</strong>, the <strong>average per iteration</strong> and the <strong>estimated time left</strong>.</p>

+"""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.
