catarrh a37266f865 v3.25.0 review: the DF-tree ARR resolution walk-up
The live card references 6F06 from MF-tree files (MF/7F20/6F07 ->
8B 03 6F06 14), but the resolver compared only the path's first
segment: the reference fell back to the ADF.USIM copy instead of the
file's own DF copy (ISO 7816-4 5.4.3.3 / TS 102 221 9.2.7 walk-up) -
masked on this card only because all four copies are byte-identical.

- The server reads the DF.TELECOM and DF.GSM copies too (MF/7F10/6F06,
  MF/7F20/6F06 - TS 51.011), best effort.
- fcpArrRules resolves by the file's DF chain (own DF first, then
  walking up to MF); a reference with no copy in the chain resolves
  only when a single candidate exists, otherwise it stays silent.
- The implicit form prefers the file's DF copy (6F06), walking up to
  the MF copy (2F06).

Tests: the DF copy wins over the ADF copy; two candidates outside the
chain stay unresolved; a single one resolves; the implicit walk-up;
the server reads the DF-tree paths.  879 frontend + 858 Python;

catarrh b6537bd54b v3.24.0: the EF.ARR access rules in the FCP view
The file manager's decoded FCI shows the '8B' security attribute
reference (EF_ARR 2F06, record 23).  The referenced record's access
rules are now rendered as indented muted lines under that row, decoded
with the existing EF.ARR record decoder (AM_DO/SC_DO conditions).

The server reads the card's ARR copies (MF/2F06 and ADF.USIM/6F06,
best effort) once per card session in _apply_equipped_card and keeps
them as server.arr; GET /api/arr serves the cache without the card
lock, a disconnect clears it, and a write to an ARR copy through
/api/write refreshes it.  The PWA fetches it lazily per card session
(pysimArrEnsure, keyed by card_session) and resolves the reference with
the selected file's DF context: an ADF.USIM file uses the ADF's 6F06
copy, the implicit reference form too (ISO 7816-4 5.4.3.3 lookup
order).  Unresolvable references stay silent.

The '8B' decode now covers all three ISO 7816-4 Table 25 forms:
implicit ARR byte / FID + record / FID + (SEID, ARR) pairs - the pairs
form was mis-decoded as a record before.  A snapshot resolves the same
references offline from its own captured EF.ARR copy.

Tests: the three forms, the resolution (DF preference, out-of-range
silence), the snapshot path, the server read/cache/route/write-refresh.

catarrh e0dfc1032e v3.23.5: the TERMINAL RESPONSE result list and its spec corrections
The step editor's result select (the expect's respond, the proactive-drain's
respond/first) offered five symbolic values with no hex.  It now offers the
full TS 102 223 v18.3.0 8.12.0 list (00-3F), labelled '<hex> - <alias>' (or
'<hex> - <spec name>'), plus a manual hex entry, and an optional
additional-information byte for the general result (83 02 <result> <info>,
default 00; the 8.12.2 terminal-problem values are suggested through a
datalist).

The script aliases were corrected to the spec: refused 03->22,
not_understood 04->32, modified 06->07, no_response 22->12 - a stored script
using one of them now answers with the corrected value; no_response stays
accepted for compatibility but is no longer offered by the editor.

The server's TR decode tables (_RESULT_NAMES_BASIC/_GENERAL, a GSM 11.14
mix displayed in the proactive log) are replaced by the spec table plus the
8.12.2 additional-information names; the dcs field parses as hex (0A used to
be refused and 10 read as decimal 10); the drain summary's 22 label is fixed.

The result labels are not translated (spec text); the unused RU keys were
removed.  Shared fixture frontend/tests/tr_results.json, drift-guarded by
both suites.  855 frontend + 838 Python; sw cache simple-v418.

catarrh 9ef1a59f2c v3.23.1: the PLI dictionary defaults and the PLI codec tag fixes
An unconfigured PLI dictionary answered result-ok with no data object,
which confuses applications that expect data.  The dictionary now has a
base layer of sensible defaults for the qualifiers the pinned ETSI specs
define (TS 102 223 8.x, tags per TS 101 220 V18.3.0 Table 7.23):

- location as the test network 001/01 + LAC 0000 (8.19),
- the classic test IMEI 490154203237518 as F-padded BCD (8.20) and its
  IMEISV (8.74),
- language 'en' (8.45), Timing Advance (2E/AE), E-UTRAN (8.61; UTRAN +
  E-UTRAN for the multiple-technology qualifier 0E),
- automatic search mode (8.75), a full battery (8.76).

An override set through /api/pli-dict wins, and clearing a field restores
its default (the PWA's Save re-renders the effective values; the GET returns
the override or the default for the full qualifier set).  The date/time
qualifier stays empty so the host clock keeps answering it; the
3GPP/3GPP2-specific qualifiers (NMR, ESN, MEID, CSG/HNB, WLAN, slices,
CAG, ...) stay empty - the ETSI specs define no contents for them, and a
fabricated object would mislead the application more than no answer.

Verifying the values against the pinned tag table exposed pre-existing bugs
in the PWA's PLI inline codecs, fixed here:
- Timing Advance used C6 (a 3GPP2 tag) -> 2E/AE;
- IMEISV used 94 (the IMEI tag) -> 62/E2;
- Network Search Mode used AD (the Language tag) -> 65/E5, and its labels
  were swapped ('00' Manual / '01' Automatic per 8.75);
- the battery field was a percentage where 8.76 is an enum ('00' very low
  ... '04' full, 'FE'/'FF');
- encImeiPli padded the odd 15th digit with 0 instead of F (TS 124 008).

catarrh 6bea57599c v3.23.0: the start-with-reset suite option
A suite may carry `start_reset` (store schema v2, default false; the editor's
"Start with card reset" checkbox): before the run, the server physically
resets the card and runs the full re-initialization - `_card_reset_reinit`
(extracted from the eSIM profile-switch reinit) does reset_card() + equip +
_apply_equipped_card + the shell registration probe.

The reset runs in _test_suite_run_request before the preset/ADM checks:
- the run's preset must still match the post-reset ICCID (a mismatch refuses
  the start with a re-select hint),
- a require_adm suite re-verifies the ADM for the new card session (the
  latch is per session).

The suite report carries start_reset + reset {ok, iccid, ms}; the PWA shows
"started with a card reset" in the report header and a RESET badge in the
suite list.  Mid-run resets stay fatal.

Documented caveat: the init drain consumes the card's initial proactive
commands, so a script cannot catch the first command after the reset (they
stay in the proactive log).

catarrh 00675ca09c v3.22.7: a raised card error honours the step's on_fail
The runner's step loop caught an exception and hard-coded status "error" +
stop, ignoring on_fail - so a file-read of an absent optional file
(re-verified live on 3.22.6: MF/A153/49AC, note "6a82: Wrong parameters -
File not found", on_fail "warning" still stopped the run) could not express
the "read an optional file" pattern (49AC is documented optional: its
absence means no menu password).

The handler now treats a raised error as a failed "Error" check at the
step's level (the message as actual/detail and the note): on_fail "warning"
warns and the run continues, the default still stops; the drain-if-pending
behaviour is unchanged.  Every raised exception is treated the same - the
two "file absent" raise paths (pySim's SwMatchError for model files and
probe_file's RuntimeError with the decoded SW for custom FIDs) cannot be
told apart by type, and load-time validation (normalise_script) stays
strict.

Docs: the guide's on_fail paragraph and run-errors list (the 6A82 bullet),
api.md and help EN/RU.  Tests: a raising file-read with on_fail "warning"
warns and the next step runs; without on_fail the run still stops.

catarrh 320854eebc v3.22.4: the proactive-drain pending exemption
The runner's unexpected-pending-command guard fired for any non-expect step,
so a proactive-drain after a step that answered 91XX failed with
"unexpected proactive command pending (SW 91XX) - add an expect step or a
status action" - contradicting the drain's own doc ("consume whatever the
card announces") and the v3.22.2 RAM recipe ("an expect or a proactive-drain").

The guard now exempts a proactive-drain step: its STATUS poll re-announces
the unfetched command, fetches and answers it, and the drain's final-SW and
pending handling is unchanged (a still-pending card is handed to the next
step, an idle card passes).  No pending-length plumbing: STATUS-first keeps
the drain's attempts/log semantics and tolerates a card that dropped the
command.  The guard note now names the drain instead of the misleading
"status action" (a status action in that position also trips the guard).

catarrh 7d997272ef v3.22.3: the mismatch on_fail, the self-healing move, the pruning reconciliation
Three test-management issues:

- an expectation whose command type did not match the pending command
  hard-coded level 'error', so on_fail "warning" tolerated "no command
  pending" but not "a different command is pending".  The check now honours
  the step's on_fail - the tolerant form for "the applet either asks X or
  does Y" (the mismatched command is still fetched and answered).
- moving a script between suites could answer 500 and leave two owners:
  _test_script_move detached only from the suite named by the script's
  suite_id and appended to the target unconditionally, so a duplicate
  listing or a stale suite_id (a hand edit, an interrupted move) collided
  on the attach.  It now detaches from every suite that lists the script,
  takes the on_fail from the explicit owner (suite_id if that suite lists
  it, else the first lister), updates the script first (a refused
  validation changes nothing) and re-attaches with a prune; the same-suite
  no-op only applies when the target really is the only lister.
- reconcile_scripts_to_suites() now prunes duplicate listings to the
  explicit owner (it only adopted before), so those states self-heal at
  startup and after a bundle import; the "Imported scripts" suite is only
  created when there are orphans.

Docs: the bundle-import note (importing into the source store duplicates
the suite and its scripts - the round-trip is not idempotent) and the
expectation on_fail clarification.

catarrh a76e0154b6 v3.22.2: the runner's TERMINAL RESPONSE inherits the terminal's own objects
Two reported gaps:

- a scripted PROVIDE LOCAL INFORMATION expectation answered with an empty
  TR - the PLI dictionary (and the host clock for the date/time qualifier)
  was silently inert during runs while the poll path used it all along, so
  an applet waiting for its data stalled behind a passing expectation.  A
  POLL INTERVAL expectation likewise never echoed the Duration (6.8.4).
  testscript.build_tr() gained `answer_tlvs` (inserted after the Result per
  the 6.8.0 order, before text/item/raw) and the shared
  _test_terminal_response() wires the expect step, the proactive-drain
  action and the run cleanup to it; the script's `raw` overrides, and a
  non-success result gets no data object.
- a GP INSTALL/LOAD/DELETE step always failed the default exact-9000 check
  although the envelope SW 91XX is the successful answer (the re-announced
  SET UP MENU; XX is the pending command's length, never pinnable).
  Documented rather than loosening the default: a new "Driving a RAM install
  from a script" subsection in docs/test-scripts.md (the 9??? mask + por
  any, the per-step pending rule - a proactive-drain/expect after every
  91XX step), a sentence at the sw-default bullet, and an scp80
  default-pinning test.

catarrh f0a836363c v3.22.1: rename the proactive action kind to proactive-drain
The kind string `proactive` read like an expectation of a proactive command
(`expect` is the step type for that) although the action consumes and answers
them.  Renamed everywhere:

- ACTION_KINDS / TEST_ACTION_KINDS (drift-tested), the normaliser branch and
  its error strings, the dispatch and the helper names (_test_run_drain,
  _drain_require_match/_label);

catarrh e12dfc7871 v3.22.0 (review fixes): the quota zero, the suite repair paths, the docs
Second review round on the unpushed v3.20.0-v3.22.0 batch:

- install parameters: a zero memory quota (nv_quota: 0 - the vendor
  reference form's C7 02 0000 C8 02 0000) is composed instead of being
  dropped as "unset" (only None/blank leaves the TLV out); a truncated EF
  length in stk_params is refused instead of read as an empty EF.
- test suites: a suite whose member script is gone is repairable - the
  update endpoint accepts pruning a dangling reference (a removal of a
  live script stays refused; the PWA's row Delete prunes it), and
  reconcile_scripts_to_suites() lists an orphan even when its suite_id
  write is refused by the validator, so a stored script that no longer
  validates stays visible in the editor and fails at run start with the
  message instead of disappearing.
- engine/PWA: the proactive action refuses a check.data (its result data
  is the drained-command list - the check was silently ignored); the
  vestigial _testScriptDraft is gone; berLenStr emits the 2/3-byte BER
  long form (a >255-byte C9 composes correctly).
- docs: api.md (the stop cleanup answers ok, never an automatic cancel;
  the server persists the counters - the PWA does not write them back; the
  suite bundle import always merges the scripts; the quota-0 note) and
  test-scripts.md (the event action covers all modelled events; the
  direct-create path needs a suite_id; the format history); help EN/RU
  counter wording.
- tests: the zero quota / truncated EF, the prune path, the invalid-script
  listing, the proactive data-check refusal, berLenStr and the >255-byte

catarrh b2cb42caf5 v3.22.0 (review fixes): the ownership reconciliation and the import guards
The suite/script ownership invariant could break silently: a suites import
with mode "replace" wiped the suites while their scripts stayed behind
(suite_id pointing at gone suites - invisible in the UI), a scripts import
with mode "replace" left every suite's member list dangling, and a script
whose suite_id disagreed with its listing suite stayed inconsistent.

- server: reconcile_scripts_to_suites() repairs the invariant - a script a
  suite lists adopts that suite (the member list is authoritative), a script
  no suite lists joins "Imported scripts"; migrate_scripts_to_suites()
  delegates to it (the startup migration is the same pass) and the suites
  import runs it after loading, so a "replace" adopts the wiped suites'
  scripts instead of losing them.
- the scripts import refuses mode "replace" while any suite still lists
  scripts (400 naming the dangling references; merge is the normal path).
- nits from the review: a legacy numeric `event` is no longer parsed as hex
  in the step summary/error check (0x0A displayed as 0x10), and an integral
  float memory quota (a JSON client's 200.0) is accepted.
- tests: the reconciliation (missing suite, listed-but-mismatched,
  idempotent), the scripts-replace guard (refused/allowed), the
  suites-replace adoption, the float quota, the numeric-event summary.

catarrh 40c1e0f148 v3.22.0: the event action uses the Simulator's forms (all modelled events)
The test-script event action edited its fields as a JSON textarea and only
accepted the four events events.py builds; every other event needed the raw
envelope action with hand-copied hex.  It now renders the same EVENT_FORMS
form the Phone tab's send dialog uses, for every modelled event (29; no
release gating - a script may target another card).

- PWA: the field renderer/collector is shared (eventFormFieldsHtml /
  eventFormValues / eventFormPatternError / eventFormSrc / eventFieldGroupsUpdate);
  the Phone tab keeps its ids, its release gating and its onchange updaters,
  the step editor uses test-f-ev- ids, the generic group updater and a live
  Event data (hex) preview with the one-ENVELOPE check.  The event select
  lists all EVENT_FORMS events (the numeric keys are decimal strings -
  parseInt(k, 10)); the action stores the collected fields, the built data
  and the event's source (fixed cfg.src or the cfg.srcField input - the
  action never carried src before, so MT call / IMS registration / slices
  could not be network-sourced).  The JSON textarea is gone.
- engine: the `event` action keeps `fields` validation for the four
  server-built events (a stray data hex is ignored) and accepts the
  form-built `data` for every other event - hex-validated and checked
  against events.EVENT_DATA_MAX (244, the one-ENVELOPE budget; server.py's
  _EVENT_DATA_MAX now reads it from events.py).  The runner builds the four
  at run time (fresh host clock) and sends the stored data for the rest.
- tests: the engine's data path (accepted / missing / malformed / oversized,
  the four still fields-built), the runner sending the data (fake scc), the
  editor's collect/prefill/patterns/source (Node), the shared helpers.

catarrh 5976ef89b4 v3.22.0: the test suites (scripts grouped, ordered, with setup/teardown)
A suite is the root object: every script belongs to exactly one suite, the
suite holds the ordered member list by reference - the optional setup first,
the members, the optional teardown last - and runs them in one card session,
without resets and without resume.

- test_suites.py: the suite store (test_suites.json, --test-suites), validated
  and atomic like the script store: roles normalised (setup first, teardown
  last, at most one of each, a script appears once per suite), per-member
  on_fail stop/continue and the suite-level require_adm.
- test_scripts.py schema v2: suite_id/require_adm; list_by_suite()/orphans();
  the import reports the id_map a bundle import remaps with.  v3.21.0 scripts
  without a suite are attached once to an auto-created "Imported scripts"
  suite (migrate_scripts_to_suites, called from __main__).
- API: /api/test/suites (+ update|delete|import - delete refused while
  non-empty; the bundle import imports the scripts first, remaps the suite
  references and skips unresolvable ones); the scripts endpoints gain
  suite_id/require_adm plus move|copy (delete detaches from the suite first;
  a suite update refuses a membership change).
- runner: /api/test/run {suite_id} resolves the members and the preset, runs
  the ADM gate, then setup -> members (per-member on_fail) -> teardown.  The
  teardown always runs on a stop or a failure (skipped only when the card is
  gone; it clears the stop flag for its duration); a card reset stops the
  suite, skips the remaining members and is flagged.  Members' live steps land
  in the shared snapshot, their records (status/steps/note/log excerpt/
  counters) in _TEST_RUN['suite']; the summary carries the counts, wall time,
  preset, the SCP80 counters before/after per keyset and the session flags.
  _test_log buffers the semantic lines (bounded) for the report's per-member
  excerpts.
- ADM gate (_ensure_adm): a suite/script require_adm verifies the matched
  preset's key once per card session (the /api/verify-adm badge sets the same
  latch); a failure refuses the start, stamps the session (no automatic
  retry) and needs a manual verify.
- PWA: the Test script pill becomes four views - the suite list (default),
  the suite editor (the script list: role badges, on_fail, up/down, per-script
  Run/Edit/Move/Copy/Delete, Add script with the templates), the script editor
  (the step list; a single run shows its result under the steps and is not
  preserved) and the suite report (per-member blocks with the step table,
  notes and run log; summary; export JSON/Markdown).  Suite bundles export/
  import; the legacy script export imports into "Imported scripts".  EN/RU.
- tests: the suite store/migration, the runner orchestration (order, on_fail,
  setup failure, stop, card reset, teardown, per-member logs) and the ADM gate
  (Python); the suite HTTP paths; the PWA report/Markdown/wiring (Node).

catarrh e6ced47323 v3.21.0: the test-runner tolerance batch + the proactive cleanup action
Five reported issues, plus the action that makes an explicit drain possible:

- on_fail is honoured by every step failure: an expectation with no pending
  command (or a FETCH that returns nothing) fails as a Command/Fetch check at
  the step's level instead of raising past it; the default still stops the
  run, on_fail "warning" continues (the tolerant consume-if-pending form).
- the run cleanup answers ok (0x00) and keeps draining while the TR answers
  91XX (bounded); a cancel is only sent when a script asks for it - it tells
  the card the user aborted the session and pushes assertive applets onto an
  error path.
- new `proactive` action: STATUS rounds consume every announced command
  (respond/first TERMINAL RESPONSE results, attempts/interval_ms bound) until
  the card answers 9000; an optional require asserts at least one drained
  command (an empty drain fails it), the final SW is the step's SW check and
  a still-pending command is handed to the next step.  PWA editor + summary +
  validation, EN/RU help, docs, action-kind drift test.
- the PoR response form follows the command's TAR: _tar_is_rm (preset role
  entries + the TS 101 220 Annex D ISD/RFM allocations) decides; a non-RM
  TAR's reply is always raw (TS 102 226 4) - no fabricated status word even
  when the bytes happen to parse (01 00 0B 91 ... used to read as SW 000B).
- a secured data too short for the compact structure (a 2-byte applet reply)
  is recovered by _por_header_parse (the decode minus the compact parse; a
  malformed packet or a failed RC/CC/DS check still yields no por) and
  reported raw, so short applet replies are assertable via por.data.

catarrh 82c5733906 v3.20.0 (fix): the install-parameter composition - one System Specific Parameters EF
Two reported SCP80/RAM issues, both confirmed against the specs:

- docs/api.md called `stk_params` a "Hex CA TLV", but TS 102 226 8.2.1.3.2.1
  puts the CA *inside* the System Specific Parameters EF ('EF'), and the PWA
  builds `EF <len> CA <len> ...` (the SIM access domain leads the CA value as
  `01 <ad>` / `00`).  A client following the doc sent a CA at the wrong level.
- the RAM composition appended the STK part after a caller-composed
  C9+EF(quotas) prefix, producing TWO EF objects.  The card read the first
  (the quotas) and ignored the CA: the install was accepted (por_ok) but the
  toolkit parameters were never registered, so no STK menu appeared (live
  2026-10-05).  Per GPD_SPE_013 v1.1 Table 6-5 (pySim's
  gen_install_parameters) the quotas (C7/C8) and the CA share ONE EF; an
  EA-form STK part is a sibling of EF (the reference TCA loader's
  `C9 00 EF 00 EA ...`).

- server: `_compose_install_params()` (used by `_cap_install_apdu` ->
  `_cap_apdu_sequence`, hence /api/ram-install, /api/ram-install-app,
  /api/scp81/gen-install and the PWA's install script template) enforces the
  rule: a caller-composed EF plus an EF-form `stk_params`, a bare CA, a
  malformed EF and quotas next to a non-empty `install_params` are refused
  (400 / `{"ok": false}` with the fix named); with an empty `install_params`
  the quotas and an EF-form CA are composed into one EF
  (`C900 EF{C7?,C8?,CA}`), an EA part stays a sibling.
- the documented `nv_quota`/`volatile_quota` fields are now real (they were
  named in the docs but implemented nowhere): integers composing C8/C7.
- PWA: `composeRamInstallParams()` composes the same single EF itself (a
  CA-form STK field takes the quotas into its EF, the merged EF travels in
  `stk_params`), the RAM install bodies send it, the placeholder shows it

catarrh bf6730f028 v3.20.0 (review fixes): the PoR decode uses the effective counter; the PWA fallback matches the server's seed
Two boundary flaws found reviewing v3.20.0:

- /api/send-ota decoded the PoR with the request's `cntr`, not the counter
  the packet was actually built with.  With the new seeding an omitted
  counter is the normal case, so a warning ENVELOPE's verdict - notably the
  live card's cntr_low PoR - could fail its RC/CC check and be lost (the
  success and the failure path are both fixed).  Tests pin the decode counter
  on both paths; the failure path also echoes the effective `cntr`.
- the PWA's effective counter (preview / verify / the older-server fallback)
  fell back to the preset's first keyset and then 1, while the server's empty
  seed builds counter 0 (no preset / kvn 0 / an unknown keyset).  A manual
  form or a keyless packet then produced a spurious "Verify vs pySim"
  MISMATCH and a preview that differed from the delivered packet.
  spPresetCounterValue()/spCntrEffective() now mirror _preset_counter_seed()
  exactly: the packet's matched keyset, else 0.
- the `OTA SEND: counter not tracked` line reflects the effective counter (a
  seeded value is logged too); docs/api.md records that the seed uses the
  packet's keyset whatever SPI1.b5b4 says.

catarrh 85cc4b9535 v3.20.0: the server-owned SCP80 counter (an untouched field = the preset's next value)
The counter an operation consumed was re-entered by the PWA on every send
(the form field was filled from the preset and posted back), so a stale tab
could send a value the card rejects (cntr_low), and typing in the field
silently wrote the preset.  Now the store is the single source of truth and
the form field is a per-send override (Option B).

- _preset_counter_seed: an explicit `cntr` in the request wins (a hand send,
  the counter probe or a pre-built packet may deliberately pick one);
  otherwise the preset store's value for the packet's keyset.  Wired into
  /api/send-ota (the APDU path; the pre-built `sp` path keeps the caller's
  bookkeeping value - the packet carries its own counter), /api/ram-install,
  /api/ram-install-app, /api/cap-compat, /api/tar-probe and /api/sp-verify
  (the reference must use the counter the JS packet was built with).
- the send-ota response echoes the effective `cntr` (a caller that omitted
  one learns what was used) and the OTA SEND log line prints it.
- persistence is unchanged and monotonic (presets.set_counter refuses
  backwards writes), pinned by tests: an explicit lower counter is used for
  the packet but never lowers the store, a higher accepted one is saved.
- PWA: the Secured packet counter field starts empty with the preset's next
  value as its placeholder (auto: <cntr>); typing affects that send only and
  is never written to the preset (spCntrSyncPreset is gone), spParams /
  getRamSpParams omit an empty counter, the RAM/send flows sync only the
  local preset copy (forward-only) instead of filling the field, the +/-
  buttons start from the effective value, and the preview/verify packet is
  built from the effective counter (genSp).  Placeholder translated EN/RU.
- the runner and /api/counter-probe keep their existing seeding (the probe
  already starts at the failed value and walks above it).

catarrh 14c43f37b3 v3.19.1: the compact-PoR decode guard (applet TAR responses reported as data)
pySim's CompactRemoteResp was applied to every response packet, so a
third-party applet's own TAR response parsed as count=128/SW=0110/data=''
(live 2026-10-04: the alfa-dsa applet's `80 01 10`) - a fabricated status
word and a lost response.

_decode_por now takes the plaintext command script's length (cmd_len): the
compact structure's command count cannot exceed it (TS 102 226 5.1.2
Table 5.1 - each command needs at least one byte), so a larger count is
classified `response_type: 'raw'`, the secured data becomes
`decoded.last_response_data` (a por.data check matches it) and no SW is
decoded; `secured_data` is exposed in every case.

Callers pass cmd_len where they know the plaintext: the test runner's scp80
step (None for a pre-built packet; carried in ctx['last_scp80'] for the
submit-PoR path), /api/send-ota (both paths), the RAM step sender and the
counter probe; a caller without it keeps the previous parse.

An audit of docs/test-scripts.md against the engine (testscript.py,
events.py, the runner) found a handful of doc-level gaps, now fixed:

- the scp80 param defaults (tar = the preset's ISD role TAR, spi1 = that
  TAR's MSL, spi2 = 01, kvn = the first keyset);
- the counter rule as implemented: the run advances/persists the counter
  after every answered scp80 step when SPI1 requests a counter check
  (refused packets move the local value forward too - it only moves up);
- respond is optional (an omitted object answers ok/0x00);
- the run-log section: the exact READ BINARY/READ RECORD/UPDATE BINARY,
  SCP80 WRAPPED=/SP= and 'TEST-RUN step N failed:' lines;
- Known limitations: an expanded-format 61xx has no in-packet GET RESPONSE
  (TS 102 226 5.2.1.1) - send the GET RESPONSE as a follow-up scp80 step;
- sms check da: a leading + and whitespace are ignored.  The engine now
  drops the + (the TPDU carries the international flag in the dialling
  type, so '+79...' could otherwise never match the parsed digits);

Review of 7250dbd:
- the step editor's menu-select form gains a Match case select
  (Case-insensitive (default) / Case-sensitive); the step summary flags a
  case-sensitive step with (case), the saved params carry
  case_sensitive: true only when chosen, and the docs say the editor
  authors the flag.
- docs/api.md: fix the 'with an optionally' grammar.
- the Variant-2 menu test's comment claimed a contains match while it is an
  exact one; a real contains leg is added ('ыбор' -> item 128).
- timeless rationale for the case-insensitive default; the format note now
  dates the change.

catarrh 7250dbd63a v3.19.0 (cont.): live fixtures; menu text match is case-insensitive by default
No test scripts have been authored yet, so the format is still free to
change - the menu-select text match is now case-insensitive by default
(menu labels are UI text; case_sensitive: true still forces an exact-case
match, and a miss on it names the case-insensitive candidates).

Verification against the live card's own bytes (captured 2026-10-04):
- the Annex A Variant 2 Cyrillic menu (ids 128..130) resolves by text and
  the case behaviour above is pinned ('кофе' -> item 130);

catarrh 92506e72b9 v3.19.0: the applet-agent script batch - por objects, alpha/sms checks, scp80 format
The test scripts get the pieces an applet test needed:

- scp80 check.por accepts an object {status?, sw?, data?} asserting the
  decoded PoR of this very exchange (inline or via SEND SHORT MESSAGE);
  the evaluation is shared with the expect-step por check
  (_por_check_results).  The editor's PoR select gains 'custom' with the
  three fields (an empty object refuses on save).
- a new alpha content check reads the command's Alpha identifier (05/85,
  Annex A coded) - the text check stays bound to the 8D Text string, so a
  command carrying both keeps them distinct.
- a new sms content check asserts a SEND SHORT MESSAGE's submit TPDU:
  DA / PID / DCS / UDL / UD (the parsed fields are logged and reported;
  an applet's own SMS, not the OTA PoR the por check decodes).
- scp80.params.format wraps the C-APDU in the TS 102 226 5.2.1 Command
  Scripting template (expanded = AA..., expanded-ae = AE 80...00 00); the
  log shows WRAPPED=, the report C-APDU=<effective> format=<fmt>.
- docs: Worksheet 1 addresses an RFM TAR (B00000/B00001/B00010 compact,
  B00120/B00140/B00130 expanded) with the own-TAR and MSL/spi1 notes, and
  file-write is documented as a direct APDU that does not fire
  EVENT_REMOTE_FILE_UPDATE.

catarrh 1aa1b44063 v3.18.1: the raw envelope action takes the source override too
The events without a semantic builder (MT call, IMS registration, slices, ...)
are network-sourced, but the raw `envelope` action had no `src` override - the
only way to express them was the semantic set.  `envelope` now accepts
`src` (82 terminal / 83 network) exactly like the `event` action; the step
editor exposes it and the authoring guide gets the row.

Also: the guide marks `por` as SCP80-only (the normaliser refuses it
elsewhere) and the semantic-events section names the shared src override.

catarrh fb4e4bd7b2 v3.18.0: the semantic event action for test scripts
The other-applet batch: a test script can send the common event downloads
semantically instead of raw hex.

- events.py: server-side mirrors of the PWA's event forms for Location status
  (0x03), Access technology change (0x0B), Network rejection (0x12 - the
  LA/RA/TA object selected by the registration group, the extended EMM cause
  and the extended information object) and Data connection status change
  (0x1D - status/type/TI plus the optional cause, host-clock 8.39 date-time,
  location information, access technology, APN and PDP/PDN/PDU type).  Fields
  are validated before the run (a bad value is a script error, not a step
  failure); `src` overrides the device-identities source (default terminal,
  matching the Phone forms).
- The engine gains the `event` action kind; the runner builds and sends it.
  The PWA's action-kind list stays in sync (drift-guarded - the guard itself
  caught its own regex bug on the first run).
- Byte parity: the vectors are generated from the PWA's own builders and
  pinned in tests/test_events.py; the frontend suites assert the same values.
  PLMN and SCTS helpers are mirrored too.
- The Phone tab's event form shows the built "Event data (hex)" (updated as
  the fields change), so every event without a builder can be used through
  the raw `envelope` action.
- The test-step editor offers the event select + a JSON fields textarea;
  malformed JSON refuses the save with a clear message.
- docs/test-scripts.md (the semantic-event table, an event example, the
  format stamp), docs/api.md and help EN/RU updated.

catarrh 0b9e9e4c5e v3.17.0: test scripts for the applet handoff - menu by text, spec-order TRs, codings
The applet-testing batch agreed after v3.15/3.16:

- menu-select by text: the step names the item by `text` (+ `mode`
  exact/contains, `case_sensitive`) instead of the install-dependent id
  (both or neither is refused); the runner resolves it against the card's
  cached menu and raises a step error naming the available items when nothing
  (or several items) matches.  The cache is refreshed on every SET UP MENU
  fetch - the proactive chain and the expect step - so an applet install (new
  items/ids after its REFRESH) no longer leaves a stale menu behind.  The
  step editor offers the id or the text + mode and the client-side pre-check
  bounds them.
- TERMINAL RESPONSE object order: both builders emitted the Item identifier
  before the Result (and the scripted builder its Text string before it too);
  TS 102 223 6.8.0 mandates Command details, Device identities, Result,
  Duration, Text string, Item identifier.  `testscript.build_tr` and
  `_menu_send_response` now follow it; `respond.raw` is documented as
  appended after the standard objects, and the exact-byte tests pin the order.
- Text codings: the scripted response codes the GSM default alphabet via the
  GSM 03.38 codec ('00' packed, '04' 8-bit) instead of latin-1, keeps '08'
  UCS2 and sends the spec's null text string for an empty answer; the packing
  helper is shared with the interactive path (`testscript.pack_gsm7`).  A
  UCS2 GET INPUT answer is documented and tested.
- docs/test-scripts.md gained the handoff brief for the applet agent: the
  value-collection table, fill-in worksheets for the two applet scenarios, a
  menu-by-text example, the validation checklist and a format stamp; help
  EN/RU and docs/api.md updated.

catarrh 8430dd1694 v3.16.0: test scripts move to a server-side store
The scripts lived in the browser's localStorage although only the local
server can run them.  The new test_scripts.py store
(~/.pysim-simple-server/test_scripts.json, --test-scripts PATH) sits next to
the card presets: stable uuids and timestamps, atomic writes, and every
mutation is validated with the runner's own engine (the submitted shape is
kept - the normaliser's output is not re-normalisable: it fills defaults
like an 'any' PoR check that the check normaliser then rejects), so a stored
script cannot fail at run start for a validation reason.  Import accepts the
old localStorage export as-is (export/import remains the migration path; the
PWA import also takes an exported array).

- /api/test/scripts (GET card-free: path/count + scripts), POST create,
  /update, /delete and /import serve the store; the endpoints answer 503
  without a store and 500 on a write failure, like the preset endpoints.
- /api/test/run takes a stored script_id (resolved when no inline script is
  sent); the PWA sends the edited copy inline plus the id for the report,
  and the run snapshot carries script_id.
- The PWA's Test script pill loads from the store, writes through on edits
  (debounced name, immediate step/new/copy/delete), reports load/save/delete
  failures inline, and exports the portable {name, steps} shape.

catarrh abc9ea2751 v3.15.0: test-script fixes for applet testing - preset id, kvn, PoR and file-list checks
Three gaps blocked SCP80 applet testing from the PWA:

- testRunPreset() still marshalled the pre-v3.8 flat preset fields
  (kic/kid/keys/counter/tar/spi1/spi2, all empty on a stored preset), so
  every SCP80 run failed with "SCP80 preset is incomplete: no keyset is
  defined".  The PWA sends the matched preset's id now and the server
  resolves it from the store (_test_run_preset_from_body; the inline
  `preset` body stays for API callers), so a run always uses the stored
  keysets, TARs and counters.  Regression tests on both sides.
- testscript._normalise_params dropped the scp80 step's `kvn` (the editor
  exposed it and the runner and validation consumed it, so scripts
  silently used the preset's first keyset).  kvn is validated (1-15) and
  passed through; the client-side problem check bounds it too.
- The PoR delivered as a SEND SHORT MESSAGE (PoR-in-submit, SPI2 bit 0x20)
  is decoded for the expect step that fetches it: the new `por` content
  check asserts the response status / R-APDU SW / response data, decoded
  with the preceding scp80 step's context (concatenated SMS accumulate
  across expectations).  The inline transport stays on the action
  (check.por / check.data).
- The new `files` content check asserts the File List of a REFRESH
  (TS 102 223 8.18, tag 12/92) - e.g. qualifier 00 = NAA initialization
  with full file change notification - as an order-insensitive set of FID
  paths.

The ladder only advances on cntr_low; any other verdict stops the search.
A stop on a non-por_ok verdict after at least one cntr_low keeps the value
anyway - the earlier rejection proves it is above the card's counter - but
the response reports success: false with counter_saved, the verdict and the
saved counter ("something is likely wrong with the security settings");
the PWA shows it amber.  Without a prior cntr_low nothing is saved, and a
missing PoR stays an error.  actual_response_sms_submit/ussd count as
accepted.

catarrh 3660a7e173 v3.12.0: the card preset carries the card's CAT (USAT) release
The release selector lives in the preset rather than a global chip: presets
already travel with the card (ICCID auto-selection, export/import), and the
operations that will consume the release are preset-aware.

- presets.py: the optional `release` field (4-18; empty = unspecified) joins
  PRESET_FIELDS; a value outside 4-18 is refused on save/import; the store
  schema version is 5.
- catrelease.py: DEFAULT_RELEASE = 12 and preset_release() - the effective
  release is the preset's own value, else Rel-12 (the safe level for cards
  whose release is not known; an unset release never filters anything away).
  The PWA mirrors both (CAT_RELEASE_DEFAULT + presetRelease()), drift-guarded.
- Cards tab: the editor's header row gains a compact CAT release select
  (unspecified / pre-Rel-6 stored as 5 / Rel-6 ... Rel-18); the empty option
  names the Rel-12 default and the tooltip explains the guard; the field is
  collected, cleared and restored with the other form fields.

  limit; maxlength=16 now, with a static guard in html.test.js.
- cardsTarAdd/cardsTarRemove re-rendered the table from the save-path
  reader, so an emptied role field was silently refilled with its default.
  The renderer no longer invents defaults; a raw reader (cardsTarsFromTable)
  feeds Add/Remove and the language-switch refresh, while the save path
  (cardsTarsFromForm) keeps the default-filling for the mandatory roles.
- the editor's dynamic TAR/keyset rows now rebuild on a language switch
  (refreshDynamicI18n) from what is typed - their placeholders and titles
  carry t() strings.  (The title/Save label were already refreshed there.)

discards; ramGoToPreset opens it too).  The editor keeps the name/ICCID
header (with From card) and groups its fields into bordered blocks:

  4-8 decimal digits) plus ADM, moved out of the top row; nothing consumes
  the PIN/PUK codes yet.
- TAR: one uniform table (TAR, MSL, description); the first three rows are
  the fixed role entries with the immutable English descriptions "ISD
  compact format" / "UICC shared FS RFM compact format" / "ADF FS RFM
  compact format"; further rows are deletable with an optional description.
- SCP80 (keyset editor) and SCP81 (PSK pair) as before.

catarrh 355bcadb59 v3.10.0 review fixes: repair /api/ram-install-app, escape quotes in esc
- /api/ram-install-app referenced undefined spi1/tar (the resolution block
  was only added to /api/ram-install and /api/cap-compat), so every request
  answered 500.  The same preset/MSL resolution is now in place, with
  regression tests for both modes (install / make selectable) and for the
  no-MSL refusal before any card I/O.
- esc() now escapes " and ' too: the TAR editor renders free-text
  descriptions (and other values) into attribute contexts, so a crafted
  preset import could inject attributes.  Three tests asserting the old
  unescaped output updated; a dedicated esc test added.
- _spi1_for_tar names the no-TAR case in its hint (a pre-built packet
  without tar/spi1 used to report "TAR ?").
- preset free TAR rows no longer store an empty "role" key (the documented
  shape); a non-list `tars` in an update is refused (400) instead of being
  silently ignored.

Live: the no-MSL request answers 400 with the hint; a make_selectable with
a bogus AID runs the format probe and the INSTALL (derived SPI1 16 from the

catarrh 6360dc5bae v3.10.0: preset TAR table with per-TAR MSL; derive the SPI1 from the TAR
Presets drop the card-wide SPI1/SPI2 and the fixed tar/uiccTar/usimTar
fields: a preset now carries `tars` - the three mandatory role entries
(isd/uiccRfm/usimRfm, spec defaults pre-settled) plus free TARs with an
optional description, each with its MSL (Minimum SPI1, TS 102 226
8.2.1.3.2.4).  v3.9.1 presets convert on load/import (the spi1 seeds all
three MSLs); duplicate TARs and empty TAR/MSL values are refused; the
store schema version is 3.

Operations derive a packet's SPI1 from its TAR's MSL (_spi1_for_tar): the
RAM ops, the test runner (per-step overrides still win), the counter probe
and each TAR-probe row; the plain send keeps an explicit SPI1 with a
`warning` when it is below the MSL, and a TAR outside the preset without an
explicit SPI1 is refused with a hint.  The TAR probe resolves per checked
TAR before sending and reports the effective spi1 per row.  The secured
packet form's SPI2 default is 00 (the RAM/probe operations pin their own).

PWA: the Cards form edits the TAR table (role rows with MSL inputs plus
Add/Remove free rows with a description), the list shows a TARs (MSL)
column, the SCP80 TAR field suggests the preset's entries (datalist) and a
preset apply seeds the SPI1 from the operation TAR's MSL with an amber
warning below it; the preset-wide SPI1/SPI2 fields and the header marker's
SPI requirement are gone (completeness = a keyset + the three role entries
with their MSLs).  Help EN/RU, docs/api.md and AGENTS updated; sw cache
simple-v358.

Live: TAR probe 000000 at its MSL 16 (registered, por_ok, counter
advanced); a send without spi1 derived 16 (por_ok, counter advanced); a
send with spi1 0A returned the warning and the card refused it (6200, no
counter consumed); an unknown TAR without spi1 was refused with the hint.

catarrh f059d05040 release: v3.9.1 - the counter probe sends a fixed read-only APDU
- The probe no longer takes a caller-supplied `apdu`: it always sends the
  read-only SELECT MF (the counter advances on the packet's security
  acceptance whatever the applet answers - 6A86/6D00 are normal there), so
  no caller can turn the sync probe into a write.
- Version 3.9.1: server VERSION, pyproject.toml and the PWA header; sw cache
  simple-v357; docs/api.md and the repo AGENTS.md updated, and the workspace
  AGENTS.md gains the v3.9.1 history entry (its "Currently" line was stale at
  v3.7.1).

catarrh 391d4a322d Low-counter reporting, counter sync probe, Bad-format decode, expanded forms
Live findings that drove this: the "card counter 0000000000" the low-counter
notice showed is not the card's counter at all (the PoR's CNTR is a copy of
the command's counter, TS 102 225 5.2 table 3, and a rejection leaves it
zeroed); and an earlier "no card accepts the expanded format" observation was
a hand-made template whose declared length did not match its body - the card
validates the lengths and answers with a Bad format TLV.

- _cntr_low_fields(status) reports the verdict as a flag; card_cntr/
  suggested_cntr and the UI's "(card counter ...)" text are gone - the value
  is not observable.  The notice offers a bounded Sync counter probe instead.
- POST /api/counter-probe: a doubling counter ladder (start+1, +2, +4, ...)
  with a read-only command until the card accepts one, then accepted+1 is
  persisted (monotonic, source counter-probe).  Rejected attempts change
  nothing on the card; the search stops at a ceiling (default FFFFFFFF, far
  below the 40-bit maximum where the counter blocks) and after max_attempts
  (default 40, clamped 1-64); a non-cntr_low failure stops it at once.
- _parse_response_scripting decodes the Bad format TLV (90, TS 101 220 table
  7.20; error types per TS 102 226 table 5.12) and returns a dict; the PoR
  carries bad_format/bad_format_name and _ram_step_result fails the step with
  "bad format 02 (wrong length)" instead of falling through to the compact
  decoder (which read the AB tag as 171 commands).
- _wrap_expanded_apdu(apdu, form) emits the definite (AA) or the indefinite
  (AE 80 ... 00 00) scripting template; the RAM command formats are compact/
  expanded/expanded-ae and _ram_detect_format probes compact, then both
  expanded codings (the expanded probes use Le='00' and no chained GET
  RESPONSE, TS 102 226 5.2.1.1).  The RAM form gains a Format selector.
- Live-verified: the verdict carries no value; the probe walked
  0x1000001/0x1000003 (low) then 0x1000007 (accepted, stored 0x1000008); the
  ISD executes both expanded codings (R-APDU 08A0000000030000000F80, SW 9000)
  and a length-mismatched template answers bad_format 02 - decoded now.
- Tests: the ladder, the probe walk + persistence, params validation, both
  template forms, the Bad-format TLV (definite and plain tag styles), the
  live ISD response through _decode_por, the step-result failure, and the PWA
  guards; help EN/RU, docs/api.md, the repo AGENTS.md; sw cache simple-v352.

catarrh 9f7876b5fa docs: help/README catch up with v3.8.0; keyset-number wording; RU "пресет"
Documentation:
- help (§1/§3): the SCP80 tab is switched by three pills - the tab list and the
  section intro now name the TAR probe (RU "TAR-сканер"); §3.1/§3.2 describe the
  Keyset selector next to the preset selector (and that a successful PoR
  advances the counter only when SPI1 carries a counter check); §4 describes
  the keyset editor rows, the derived number and the per-keyset counters; the
  probe section keeps its counter rule.
- README/README_RUS: the SCP80 tab says three pills and gains a "TAR probe" /
  "TAR-сканер" section (standard list, verdicts, counter persistence); the
  Cards section is rewritten for the server-side store - keysets, server-owned
  per-keyset counters with the audit trail, JSON export/import as the migration
  path, the keyset editor, the equipped-card mismatch banner - and the field
  table, "Add a card" and "Edit / remove" follow.

Terminology:
- "key version" is no longer used for SCP80 keysets in the UI, the server error
  strings and the docs: the selector is "Keyset", its options "Keyset 1 - ...",
  the messages say "keyset N ...".  The TS 102 225 A.1/A.2 quotes and the GP
  PUT KEY P1 field keep the spec's own wording.
- RU keeps the word "keyset" untranslated ('Добавить keyset', 'Номер keyset',
  "не является keyset пресета", ...) and uses "пресет" instead of
  "предустановка" throughout the dictionary, the help and README_RUS.

catarrh 6eeb8dacb3 feat: TAR probe + the SPI1 counter-tracking rule; keyless packets build again (v3.8.0)
Three things learned from probing a live card, plus the capability they enabled:

1. Counter tracking follows SPI1.b5b4 (TS 102 225 5.1.1): with 00 the counter
   is "present, ignored, never updated", so a packet without a counter check
   must leave every counter untouched.  _counter_tracked() now guards
   /api/send-ota (no final_cntr, no persistence, a log line), the RAM step
   sender and the test runner; _preset_counter_persist() requires a non-zero
   key version (the "single keyset" fallback could advance a keyset spuriously
   for a keyless send).  The PWA advances the form counter only when the server
   reports final_cntr and says "counter not tracked" otherwise.

2. The spec's no-security form builds again: _ota_keyset() refused the valid
   KIc/KID '00' (TS 102 225 A.2: '00' is legal with SPI1.b3=0 for KIc and
   SPI1.b2b1=00 for KID) because pySim wants an algorithm.  An unknown nibble
   is now refused only when the algorithm is actually used (ciphering / a
   ciphered PoR for KIc, RC/CC/DS / a MAC'd PoR for KID) and 'implicit' codes
   the nibble as 0 otherwise - POST /api/send-ota {apdu, spi1:"00", kic:"00",
   kid:"00"} now builds 0D00010000B0000000000000010000A40000, the exact packet
   the card accepted (a fake 15/15 was refused with 6200).  A no-security PoR
   is decodable again too, and a requested-but-missing PoR sets por_missing
   on the plain path as well.

3. TAR probe (POST /api/tar-probe, RAM op "Probe TARs"): one secured packet per
   TAR - the standard allocations of TS 101 220 V18.3.0 Annex D, Table D.1
   (TAR_PROBE_TARS), or a custom list - carrying a harmless C-APDU (SELECT MF)
   with the preset's keyset and SPI 16/01.  Each TAR is classified
   (registered / no_answer / no_por / refused) from the ENVELOPE verdict and
   the application's PoR, counters advance and persist normally, and the run is
   refused when SPI1 has no counter check.  Live on a card: 000000, B00000 and
   B00001 registered (compact-format applications, answering 6D00 / 6B00),
   the expanded-format TARs, USAT, multiplexing and CASD refused with 6200 -
   with the keyless form the same card accepted every TAR and answered no PoR.

catarrh cc2edb3d8a feat: one keyset per key version - indexed keys and counters (v3.8.0)
A card usually holds several OTA key sets, and the SCP80 counter is tracked
per key version on the card, so a preset now carries one keyset per
GlobalPlatform key version - the b8..b5 nibble of KIc/KID (TS 102 225
5.1.2/A.2), the version is implicit in the bytes.  The spec is explicit:
"a dedicated counter shall be associated to each key version" (Annex A.1) and
"the key version number indicated in the KIc and KID (bits b8..b5) fields
shall be identical when different from 0" - a mismatch is rejected by the card
with "Unidentified security error" (A.2).

Server (presets.py, schema 2):
- a preset carries `keysets: [{kic, kid, kicKey, kidKey, cntr}]`; validation
  refuses a KIc/KID version mismatch (A.2), a version outside 01-0F ('00'
  means "no security" and is a packet-level choice, not a keyset), duplicate
  versions and missing keys/counters; a v3.8.0 flat preset converts into one
  keyset on load and on import;
- `set_counter(..., kvn)` writes the counter of that keyset (monotonic per
  keyset), the audit line carries the kvn, and `find_keyset()` serves the
  lookups;
- the operations derive the key version from the request's KIc byte and
  persist into that keyset: /api/send-ota, the RAM install/install-app/compat
  steps (_ram_send_gp_apdu) and the test runner's SCP80 steps (which may name
  a `kvn` per step and keep one working counter per keyset);
- a non-zero key version the named preset does not define, or a KIc/KID
  mismatch, is refused before anything is built (_preset_keyset_check /
  _keyset_guard: 400, or a step error in the test runner).  Without a
  preset_id only the mismatch rule applies.

PWA:
- the Cards form's KIc/KID/counter/keys inputs become a keyset editor (one row
  per version: KIc, KID, both keys, that version's counter, Add/Remove; the
  version is shown derived from the bytes and a mismatch is flagged);
- the SCP80 and RAM views get a Key-version selector beside the preset
  selector, driving the KIc/KID bytes and loading that keyset's keys and
  counter; the packet builder refuses a version the preset does not define
  (spKeysetCheck/spKeysetGuard, pure and unit-tested);
- the counter syncs are per keyset (spCntrLocalSync/ramSaveCntr), the SCP80
  form's counter edit posts the keysets, and the test-run write-back syncs
  every counter the server reports (scp80_counters).

catarrh 4ab133c266 fix: v3.8.0 preset-store review findings
- /api/send-ota no longer 500s on a counter-less body: the plain `sp` path
  reports final_cntr only when the counter is usable (_counter_valid, 1-10 hex
  digits) - before, the new plain-path report ran int('') and the request died
  in the generic handler.  The failure path is guarded the same way.
- _decode_por wraps the keyset/SPI construction in the same "never raise" rule
  as the decode: a malformed counter or missing keys return None instead of
  escaping the handler.
- presets.add() never accepts a taken id (a fresh uuid is assigned, like the
  import path), the counter is validated as 1-10 hex digits instead of being
  silently masked/kept, and set_counter() ignores a malformed value with a log
  line instead of writing it.
- the preset endpoints answer a JSON 500 when the store write fails (read-only
  home, disk full) instead of dropping the connection.
- tests: counter-less send-ota, store-write 500, duplicate id, counter
  validation (add/update/set_counter), and the temp-file check no longer
  matches the audit file; docs/api.md documents final_cntr for the plain path
  and preset_id.

catarrh 795a1fea49 feat: card presets move to a server-side store; the server owns the SCP80 counter (v3.8.0)
The presets lived in the browser's localStorage and the PWA wrote the SCP80
counter back after every operation, so an increment could be lost when the
response never reached the tab, when two browser contexts (or the demo origin
plus a local one) held separate copies, or when the tab was closed mid-run.
The counter is card state and the server performs every card operation, so the
store now lives next to the server:

- pysim_simple_server/presets.py: one JSON file
  (~/.pysim-simple-server/card_presets.json, --card-presets overrides; Path.home()
  resolves the same way on Windows), atomic writes (temp + fsync + os.replace),
  an RLock, stable uuid ids, the ICCID normalisation the PWA uses (digits /
  spaced / raw EF hex), a duplicate-ICCID refusal and a monotonic set_counter;
  every counter change is appended to card_presets.json.audit.jsonl.
- API: GET /api/presets (card-free), POST /api/presets and
  /api/presets/update|delete|import; the import also takes the old localStorage
  export shape - that is the migration path, there is no automatic migration.
- Operations name a preset_id and the server persists the counter they
  consumed: /api/send-ota (the plain SCP80 path reports final_cntr now too),
  the RAM install/install-app/compat steps (_ram_send_gp_apdu) and the test
  runner's SCP80 steps (_preset_counter_persist).
- PWA: the Cards tab is a thin client of the store (load on connect, CRUD via
  the API, export/import), the counter write-backs became local display syncs
  (the SCP80 form's counter input stays a deliberate human edit) and the
  SCP80/RAM bodies carry preset_id; a new pysimFetchOk() surfaces the server's
  error bodies instead of silently using them.

Policy: card keys in logs and local files are not a risk for this workbench
tool (AGENTS.md) - the store is not encrypted and no redaction is required.

Tests: tests/test_presets.py (store: ICCID forms, counter monotonicity and
wrap, atomic writes, corrupt-file recovery, import), the preset endpoints in
tests/test_fetch_routes.py (incl. the counter persistence via /api/send-ota)

catarrh ee747003f2 feat: CAP compatibility test in the popup + per-AID failure analysis (v3.6.52)
The compatibility test now runs in the same operation modal as the installs
(live progress from the server's ram_progress, Close disabled until done) and
its result gains a per-AID detail block instead of the comma list:

- the probe summary (probe: 2 imports -> 0.0 . +1 appended);
- the import list as tested (ramCompatImportRows): the CAP's imports with the
  version the card was asked for and the CAP's own version when the probe
  lowered it, appended synthetic entries and unmatched lines - each with the
  resolved library name (jcAidName), so a raw AID list becomes readable rows;
- on a rejection, the failure analysis (ramCompatFailureHtml): which CAP
  section the failing block covers (load-file byte range and component names,
  'completes Import'), what the card checks at that point (JC VM spec 4.5.2)
  or that the import list already passed, the remote status word with its
  name, and what the probe state implies (every import at 0.0 -> a missing
  package or another load-file check is the cause; otherwise lower the
  versions and bisect).

ramCompatVerdict names the remote SW; the inline result keeps the verdict +
short probe note and the modal carries the escaped step lines + the detail
HTML (ramOpModalFinish gained an asHtml mode); the server reports
probe_unmatched as [{'aid', 'version'}] (_probe_unmatched), documented in
docs/api.md.  The same failure block for the real install is the next step.

catarrh 599d84fd66 feat: Explore exposes the rest of the registry data + install NV footprint (v3.6.51)
The compact (legacy) GET STATUS entry is <aid_len><AID><life cycle>
<privileges> + (P1=10) <module count> (<len><module AID>)*, cross-checked
against GlobalPlatformPro's populate_legacy (the 4th byte is privileges;
0x00 is required for load files).  The parser read it as a 'version' one
byte late, so ELF rows showed the module count / the next entry's length as
Version: 00/10 - the compact listing has no version at all; it now comes
from the expanded CE tag (ramFmtVersion: 2 bytes -> major.minor, GP Table
11-37 Note 1) and merges (the bogus compact value no longer blocked it).

New data exposed:
- EA SCP Registry Data (TS 102 226 8.2.1.6) -> 80 Menu Parameters -> the
  applet's STK menu entries: STK menu entry: 0x80 (position 1, Enabled)
- unknown registry objects are preserved (rawTlvs) and shown as
  'Other registry data: 8F=752B . 90=012D ...' instead of being dropped
- 84 parses the GP coding (one Executable Module AID per TLV, repeated; the
  concatenated 4F<len><aid> form stays as fallback) and the ELF expanded
  queries add 84 to the tag list (with a tag list the card returns only the
  listed tags - the fallback path would otherwise lose the module lists and
  their Install buttons)
- life cycle names decode per object kind (GP Tables 11-3..11-6: ISD/card,
  app, SD - detected via the Security Domain privilege - and ELF), with
  multi-byte 9F70 (02 0700 on live cards) decoding the first byte and
  surfacing non-zero extras; the R-APDU parser's LIFECYCLE_MAP labels were
  aligned with the same tables

/api/ram-install measures the NV footprint: a silent GET DATA FF21 read
before and after the chain (also on failure) returns nv_before/nv_after/
nv_delta; the reads never fail the operation (no FF21 -> no fields) and the
PWA shows 'NV used: ~N B (free A -> B)' in the install result.

catarrh cf931da2f9 fix: capture the submit PoR on every card + per-operation RAM format check (v3.6.24)
Comparing the new TCA vendor traces (Explore_EP/ET/NC/NP/SE) with our flow
showed why only one card works:

- The PoR capture was gated on SPI2 bit 0x20.  The traced cards deliver the
  PoR as a proactive SEND SHORT MESSAGE; with our ISD/memory queries
  (SPI2=0x01) the fetched TPDU was thrown away - the Explore died with
  "no data" and the RAM install steps silently degraded to an unverified
  "no_por".  The capture is now unconditional (inline ENVELOPE responses and
  proactive submits both work), and the STATUS-poll fallback is enabled for
  every card.
- `_ram_next_cntr` still wrapped at 32 bits (`% (2 ** 32)`): a 10-digit
  counter like 10000AAAC8 came back as 00000AAAC9 after a RAM/Explore step -
  the server-side half of the v3.6.23 counter report.  It now advances the
  full 40 bits.
- RAM command format (TS 102 226 5.2.1: compact C-APDU vs the expanded
  `AA` > `22` form) is detected per operation and never stored:
  /api/ram-install and /api/ram-install-app always probe, /api/send-ota
  probes when the caller passes `ram_format`.  The probe is a read-only
  GET STATUS [ISD] as the first step (compact, then wrapped) and every
  command of the operation uses the detected format.  `_wrap_expanded_apdu`
  is pinned to the reference bytes `AA0A220880F24000024F0000`; responses
  carry `ram_format` and `final_cntr` (accepted probes consume counters, so
  the views use the server's next counter).  Applet-directed payloads stay
  byte-exact; only RAM views (and RAM/GP chain packs) opt in.

catarrh face2268ca feat: single-APDU INSTALL [for install] / [for make selectable] ops (v3.6.18)
Iterating the final install step no longer needs a delete + re-load of the
.cap:

- `POST /api/ram-install-app` runs INSTALL [for install] (`mode: "install"`,
  P1 0x0C/0x04 by make_selectable) or INSTALL [for make selectable]
  (`mode: "make_selectable"`, GP 11.5.2.3.3 Table 11-44) for an already
  loaded package.  The APDU builders are shared with `_cap_apdu_sequence`
  (`_cap_install_apdu`, `_cap_make_selectable_apdu` - one builder, no drift)
  and the per-step send/PoR/counter logic is the extracted shared
  `_ram_send_gp_apdu` (used by /api/ram-install too).
- PWA: the RAM op selector gains "INSTALL [for install] (loaded package)"
  and "INSTALL [for make selectable]" with Load File / Module / Instance AID
  inputs (instance defaults to the module AID); the result renders through
  the shared `ramShowInstallResult` and `final_cntr` keeps the preset in
  sync.
- Explore: an **Install** button on a package's module AIDs that have no
  instance yet, and a **Make selectable** button on INSTALLED (0x03)
  instances - both switch the op and pre-fill the AIDs.
- tests: the install APDU pinned to the live no-STK packet and to the
  sequence tail, the make-selectable APDU, ramHasInstance, the Explore
  buttons and the op wiring; docs/api.md updated.

catarrh 40f20d539e fix: decode the Response Scripting template and the compact listings (v3.6.5)
Explore still missed the F0414C46416101 package on a card whose responses
wrap the R-APDU in the TS 102 226 5.2.2 Response Scripting template
(`AB <len> 80 <count> 23 <len> <R-APDU>`): `_decode_por` parsed that as a
compact response, so the frontend got `last_status_word` 81d0/7680 and data
starting `80 01 01 23 ...` instead of the listing.

- server: `_parse_response_scripting()` (AB definite / AF 80 ... 00 00
  indefinite) extracts the executed-command count and the last R-APDU's SW
  and data; `_decode_por` exposes it as `response_type: scripting` in the
  same `decoded` shape as compact, so the RAM explore paging and the RAM
  install `por_sw` see the real 9000/6310.
- frontend: the compact listing walk is deterministic on the AID length
  (`len AID life ver`; P1=10 adds `module_count (len module_AID)*`).
  `_parseRawAppEntry` no longer guesses `rawLen-1` for >8-byte AIDs (16-byte
  A113 applet AIDs were truncated), and `_parseRawElfEntry` no longer scans
  for `0x10` (a length/AID byte equal to 0x10 derailed the walk: a live page
  parsed to 1 entry with no F0414C46416101).
- tests: exact trace fixtures - the ELF page lists F0414C46416101 (11
  entries), the P1=10 page attaches its F0414C4641610101 module, the app page
  keeps the 16-byte A113 AIDs; Python covers the scripting template
  (definite/indefinite) against the live `AB 12` ISD and listing vectors.

catarrh 9e85f522f6 fix: recover the SMS-SUBMIT listings in RAM Explore (v3.6.4)
Explore returned partial data (no ELF/module entries, the installed package
missing) and then failed with cntr_low.  Two causes, both in the
actual-response SMS-SUBMIT path the card uses for big listings:

- `_find_sms_tpdu` read TLV lengths as a single byte; the FETCH carries
  `8B 81 97 ...` (BER long form) for the big pages, so it returned a
  corrupted, truncated TPDU.
- `_calc_ud_offset` treated the SMS-SUBMIT relative validity period (VPF=10)
  as 7 bytes instead of 1, shifting the UD offset: `_parse_sms_concat` then
  read a bogus UDH and reported no concatenation, so the segments never
  assembled and the PoR/data was dropped ("RAM RESPONSE-PACKET: empty").
  The step was marked failed, the counter did not advance, the same counter
  was retried and the card answered `cntr_low`, which also blocked P1=10
  (modules) where the installed package appears.

- the captured segments now always store the assembled UD (`submit_ud_hex`);
  `_sms_submit_por()` rebuilds the DELIVER-style packet (`02 71 00` + UD) for
  `_decode_por`.  Verified against the live capture: por_ok, remote SW 6310,
  438 hex chars of listing data (the exact bytes of the P1=20 page).
- `spPorAccepted` counts `actual_response_sms_submit` (0x0B) as accepted, so
  the counter advances when the data follows via SMS-SUBMIT.

Explore queries follow GP Card Spec v2.3.1 11.4.2.2: compact listings
(P2.b2=0) with the chained GET RESPONSE (`ramGetStatusApdu`, paging P2=00 ->
P2=01), the malformed P2=02 attempt is gone, and the ISD-only query (P1=80)
never pages with next-occurrence (the card shall reject it).

Tests: Python SmsSubmitCaptureTest with the live FETCH bytes (TPDU length,
UD offset, concat reassembly, 027100+UD decode); ram.test.js checks the APDU
builder and the missing P2=02 attempt; cards_counter covers 0x0B.

catarrh 39c82f26f3 fix: SCP80/RAM re-read the preset before every operation; no counter bump on a rejected send (v3.6.3)
The SCP80/RAM forms hold a copy of the preset (counter, keys, TAR, SPI).
Editing the preset on the Cards tab saved correctly, but the form kept the
old copy: the operation sent the stale counter (the card answers cntr_low)
and the post-send sync wrote the stale value back over the preset - the
saved counter silently reverted.  Reproduced in a real DOM:

  after select in SCP80:  preset=0000000001  sp=0000000001
  after Cards edit+save:  preset=00000000AA  sp=0000000001
  after a sync:           preset=0000000001  (edit lost)

- `cardsApply()` split into `cardsApplyFields()` (field copy, no packet) and
  `cardsApply()` = fields + genSp; new `spRefreshFromPreset(selId)` re-reads
  the selected preset from `sp-card-sel` / `ram-card-sel` and re-applies it.
- `pysimSendOta()` and `ramExecute()` call it before starting, so every
  SCP80/RAM operation uses the preset as it is now.
- A rejected send no longer advances the counter: new `spPorAccepted(por)`
  gates the advance+write-back in `pysimSendOta`, the Explore pagination and
  its GET DATA step, and the server's RAM install (`_ram_next_cntr`: advance
  only for `por_ok`/`no_por` steps).  A failed install still returns
  `final_cntr` (the accepted prefix) and the PWA persists it, so a retry
  never replays a counter the card already consumed.
- tests: cards_counter.test.js (the stale-form regression, RAM selector,
  fields-without-genSp, spPorAccepted) and `_ram_next_cntr` cases; the
  cards_form/ram harnesses updated for the split.
- docs/api.md counter semantics; AGENTS preset-source-of-truth rule.
