# Test script authoring guide

A **test script** is a JSON document that drives a deterministic dialogue with
the card over the local server: ordered **actions** (each sends something and
checks the response) and **expectations** (each fetches the proactive command
the card announced, checks it, and sends the scripted TERMINAL RESPONSE).

Scripts live in the **server-side store**
(`~/.pysim-simple-server/test_scripts.json`, `--test-scripts`): the PWA's Test
script pill manages them (Import/Export move JSON in and out, the old
localStorage export imports as-is), and any API client can create or run them
(`POST /api/test/run` with an inline `script` or a stored `script_id` - see
`docs/api.md`).  While a run is active the card belongs to the script.

**Test suites** (v3.22.0) group the scripts: a suite is the root object (every
script belongs to exactly one suite, `suite_id` in the script store) and the
runner executes its scripts in order - the optional **setup** first, the
**member** scripts, the optional **teardown** last - in **one card session,
without resets and without resume**.  Per member `on_fail` decides whether a
failure stops the suite (`stop`, default) or the next script runs
(`continue`); the **teardown always runs** on a stop or a failure (its job is
to leave the card ready for a new test) as long as the card is in the reader,
and a card reset (session change) stops the suite and is flagged in the
report.  A suite (or a single script) may require the **ADM** verified: the
matched preset's key is tried **once** at the start - a failure refuses the
run and needs a manual verify (the ADM badge) before the next attempt.  The
suite run's report (the PWA's report view, exportable as JSON or Markdown)
carries every member's step table, failing notes and run-log excerpt, plus the
summary (pass/warn/fail/skipped, wall time, the SCP80 counters before/after
per keyset and the card-session flag).  The suites live in
`~/.pysim-simple-server/test_suites.json` (`--test-suites`).  A bundle
import always merges: importing a suite export **into the store it came
from duplicates the suite and its scripts** (an id already present gets a
fresh uuid) - restore into a fresh store, or wipe the target first.

A suite may **start with a card reset** (`start_reset`, the suite editor's
*Start with card reset*, v3.23.0): before anything runs, the server
physically resets the card and performs the full re-initialization (ICCID,
network state, TERMINAL PROFILE, the equip drain), so the scripts run against
a freshly initialized card.  The run's preset must still match the card's
ICCID after the reset (a mismatch refuses the start - re-select the preset
and retry), and a `require_adm` suite verifies the ADM again for the new card
session.  The initialization **consumes the card's initial proactive
commands** (the menu, the event list, a PLI), so a script cannot catch the
"first command after reset" event - those commands stay in the proactive log
as evidence.  A reset *during* the run is still fatal: the suite stops and
the remaining members are skipped (flagged in the report).

**Format**: server ≥ 3.15.0 (`kvn`, `por` and `files` checks), scripts stored
server-side since 3.16.0, `menu-select` by text and the spec-order TERMINAL
RESPONSE codings since 3.17.0, the semantic `event` action since 3.18.0, the
`envelope` action's `src` override since 3.18.1, the inline `por` object, the
`alpha`/`sms` checks, `scp80.params.format` and the case-insensitive
`menu-select` text match since 3.19.0, the `proactive-drain` action (the kind
`proactive` until 3.22.1) and the
ok-answering bounded cleanup since 3.21.0, the suites and the Simulator's
event forms for all modelled events since 3.22.0, a suite's `start_reset`
since 3.23.0.

## Writing a test for an applet

Collect these values before writing the JSON (from the applet's source/spec
and the card's preset):

| What | Where it goes | Notes |
|---|---|---|
| TAR to address (the RFM application or the applet's own) + MSL, or an explicit SPI1 | `scp80.params.tar` / `spi1` | the card preset must carry the TAR with its MSL, or the step passes `spi1`; RFM TARs: `B00000`/`B00001`/`B00010` compact, `B00120`/`B00140`/`B00130` expanded (see Worksheet 1) |
| Keyset number | `scp80.params.kvn` (1–15) | only when the applet's keys are not the preset's first keyset |
| Trigger C-APDUs (+ their format) | `scp80.params.apdu` / `format` | one secured packet per `scp80` step; the preset provides keys and counter, `format` wraps the APDU for an expanded-format application |
| Expected file paths + contents | `file-read.params.path` + `check.data` | a mask must have **exactly** the actual value's length |
| Expected proactive command(s) | `expect.command` + `qualifier`/`checks` | REFRESH `qualifier: "00"` = NAA init + full FCN, `files` asserts the changed EFs |
| PoR transport + expected PoR | `scp80.check.por`/`check.data` (inline) or `expect SEND SHORT MESSAGE` + `por` check | pick per the SPI2 the applet expects |
| Delivery timing | a `status` action when the card delivers on poll | the runner never polls by itself |

### The three status words (envelope SW · PoR status · R-APDU SW)

An SCP80 step carries three different "SW" values; keep them apart when
writing checks:

| Where it comes from | What it means | Script field | Report row |
|---|---|---|---|
| the **ENVELOPE** exchange | the card's answer to the command that was sent (`9000` executed, `91XX` a proactive command is pending, `62XX`/`63XX` a warning) | the action's `check.sw` | `SW` |
| the **PoR status** | the SCP80 security-processing verdict inside the response packet (`por_ok`, `cntr_low`, `rc_cc_ds_failed`, `tar_unknown`, …) | `por.status` (or `"por": "ok"`) | `PoR status` |
| the **R-APDU SW** | the response payload's own status word - the last executed command's / GET RESPONSE's status in the compact form (TS 102 226 §5.1.2 Table 5.1), or the last R-APDU's in the scripting (`AB`/`AF`) form | `por.sw` | `PoR SW` |

`por.sw` is a child of the **response payload**, not of the envelope: it
exists only when the addressed TAR is a **remote-management application**
(ISD / RFM).  A third-party applet's **own TAR** answers with
application-defined bytes - the platform passes them through unchanged - so
there is no R-APDU SW to check: `por.sw` reports `(none)` and the whole
secured data is exposed as `por.data`.  Assert such a response with `data`
and leave `sw` empty; the step's `check.sw` still asserts the envelope
exchange.

The form is decided by the command's **TAR** (v3.21.0): the preset's role
TARs and the standard ISD/RFM allocations (TS 101 220 Annex D) are decoded as
RM responses; any other TAR - an applet's own - is reported `raw` regardless
of whether its bytes happen to parse as a compact response, so no status word
is ever fabricated (a 2-byte reply cannot be one: Table 5.1 needs the command
count plus two status bytes - it is reported raw too).

A `62XX`/`63XX` envelope answer does not guarantee a response packet: an
application that refuses at the envelope level (e.g. an applet answering
`6200` to an unknown command) sends none, while other warning paths still
deliver one (the low-counter case arrives via SEND SHORT MESSAGE).  For a
step expected to be refused, leave `por` at its `"any"` default or assert
`"por": "none"`; the run report's `PoR[…]` log line and `por` field show
which happened.

### Worksheet 1 - RFM update → file change → REFRESH (full FCN)

```json
{"name": "applet RFM update",
 "steps": [
  {"type": "action", "kind": "scp80",
   "params": {"apdu": "<RFM C-APDU>", "tar": "B00001", "kvn": 1, "spi2": "01"},
   "check": {"sw": {"mode": "mask", "value": "91??"}, "por": "none"},
   "label": "RFM update"},
  {"type": "expect", "command": "REFRESH", "qualifier": "00",
   "checks": [{"kind": "files", "value": "<changed FIDs, e.g. 3F007F206F07>"}],
   "respond": {"result": "ok"}},
  {"type": "action", "kind": "file-read", "params": {"path": "<EF path>"},
   "check": {"data": {"mode": "mask", "value": "<expected bytes, ? = wildcard>"}}}
 ]}
```

`tar` addresses the **RFM application that owns the file system**, not the
applet-under-test: `B00000` = UICC shared FS, `B00001` = ADF RFM, `B00010` =
SIM FS (compact), and `B00120`/`B00140`/`B00130` the expanded-format twins
(TS 101 220 Annex D; the probe list in the SCP80 tab carries the same names).
An applet that accepts secured packets under its **own** TAR - the TAR given
in its INSTALL [for install] parameters (TS 102 226 §8.2.1.3.2.7) - uses that
TAR instead.  The preset must carry a TAR entry **with its MSL** or the step
passes an explicit `spi1`; an expanded-format RFM application also expects the
wrapped command template (`"format": "expanded"`/`"expanded-ae"`, see the
actions table).

A **scripted SELECT inside the secured packet** should ask for no response
data (`P2='0C'`, e.g. `00A4000C02A153`): a card can refuse the `P2='00'`
form (return the FCI) with `6A86` when it arrives inside a command script,
and the script has no use for an FCI anyway.  The selects walk from the
current directory the RFM application starts in: MF for the UICC shared FS
RFM application (TAR `B00000`, TS 102 226 §7.2), the ADF for an ADF RFM
application (TAR `B00001`, §7.3).

### Worksheet 2 - incoming data → particular PoR, no other actions

Inline PoR:

```json
{"name": "applet data (inline PoR)",
 "steps": [
  {"type": "action", "kind": "scp80",
   "params": {"apdu": "<data C-APDU>", "tar": "<applet TAR>", "spi2": "01"},
   "check": {"sw": "9000", "por": "ok",
             "data": {"mode": "mask", "value": "<expected PoR bytes>"}}}
 ]}
```

PoR-in-submit:

```json
{"name": "applet data (SEND SM PoR)",
 "steps": [
  {"type": "action", "kind": "scp80",
   "params": {"apdu": "<data C-APDU>", "tar": "<applet TAR>", "spi2": "21"},
   "check": {"sw": {"mode": "mask", "value": "91??"}, "por": "none"}},
  {"type": "expect", "command": "SEND SHORT MESSAGE",
   "checks": [{"kind": "por", "status": "por_ok", "sw": "<R-APDU SW>",
               "data": {"mode": "mask", "value": "<expected response data>"}}],
   "respond": {"result": "ok"}}
 ]}
```

### Validation checklist

1. **Client-side**: the PWA import (or `testScriptProblem`) rejects structural
   mistakes; the server validates again with the same engine at run start.
2. **Import** the JSON (PWA → Simulator → Test script → Import, or
   `POST /api/test/scripts/import`; a direct `POST /api/test/scripts` needs a
   `suite_id`), select the matched preset, **Run**.
3. **Read the report**: every action/expectation shows expected vs actual per
   check; ⚠ = warning (continues), ✗ = error (stops).  A failed step names the
   reason (`note`).
4. **Iterate**: a mismatch on `data` usually means the mask length differs from
   the actual value, or the value changed between runs - mask the varying
   bytes (counter, date-time) with `?`.
5. **Counters**: the run starts from the preset's stored counter and advances
   it after every scp80 step the card answers (when SPI1 requests a counter
   check); a refused packet moves it forward too - see the presets section.

### Reading the run log

Every step writes a semantic line to the server log under its step number,
request before response:

```
TEST-RUN step 1: SCP80 C-APDU=80E2900000
TEST-RUN step 1: SCP80 SECURED=0100…1A2B (N B) TAR=B00001 SPI1=16 SPI2=21 CNTR=0000000A
TEST-RUN step 1: SCP80 -> SW=9000
TEST-RUN step 1: PoR[inline] status=por_ok TAR=B00001 CNTR=0000000A raw=0271…aabb
TEST-RUN step 1: R-APDU SW=9000 data=AABB
TEST-RUN step 2: STATUS 1/2 -> 9102
TEST-RUN step 3: FETCH=8012000002 -> SW=9000 D03C8103012500…
TEST-RUN step 3: CMD 0x25 SET UP MENU qual=00
TEST-RUN step 3: TR=81030125000202828183020000 -> SW=9000
TEST-RUN step 4: MENU-SELECT ENVELOPE=80c2000009d30702020181900101 item=1 ('One') -> SW=9103
```

- A PoR delivered as SEND SHORT MESSAGE is logged on the step that fetches it:
  `PoR[sms-submit] …` followed by the same `R-APDU` line.
- A SEND SHORT MESSAGE expectation also logs its parsed TPDU
  (`SMS DA=… PID=… DCS=… UDL=… UD=…`) after the `CMD` line, so an applet's own
  SMS can be read even without an `sms` check.
- A wrapped scp80 step logs both forms:
  `SCP80 C-APDU=<plain> WRAPPED=<wrapped> (<format>)`; a pre-built packet logs
  `SCP80 SP=…`.
- Other actions log their send/response pair too (`APDU TX=… -> SW=…`,
  `ENVELOPE(Event Download) … -> SW=…`, `READ BINARY <path>`,
  `READ RECORD <n> <path>`, `UPDATE BINARY <path>`, each with `-> SW=…`).
- A `proactive-drain` action logs its rounds (`STATUS i/N -> …`, `FETCH=…`,
  `CMD 0x…`, `TR=… -> SW=…`); the run cleanup logs
  `TEST-RUN drain: <CMD> (0xNN) TR=… -> SW=…`.
- A failing step adds `TEST-RUN step N failed (<level>): …` with the reason
  (`<level>` is `error` or `warning` - a tolerant step's line names its level).
- The shared secured-packet sender logs each segment's answer
  (`OTA SEND: ENVELOPE i/N -> <SW>`).
- `--apdu-trace` adds the raw transport view
  (`APDU-TRACE(…): <cmd> → SW: … RESP: …`) for every APDU, including the
  file-manager reads and pySim's auto-handler traffic.

## Document shape

```json
{"name": "applet RFM update",
 "steps": [
   {"type": "action", "kind": "scp80", "params": {…}, "check": {…}, "label": "optional"},
   {"type": "expect", "command": "REFRESH", "qualifier": "00",
    "checks": [{"kind": "files", "value": "3F007F206F07"}],
    "respond": {"result": "ok"}}
 ]}
```

Every step may carry `on_fail`: `"error"` (default - stops the run) or
`"warning"` (continues, the report shows ⚠).  Each entry of `checks` may
override it with its own `on_fail`.  The level applies to **every** step
failure, including an expectation that finds no pending command (v3.21.0)
and a **card error raised during the step** (v3.22.7 - an absent optional
file's `6A82`, a refused SELECT: with `on_fail: "warning"` the step warns,
the report shows the error as a failed check, and the run continues) - the
tolerant "consume a command if there is one" form is an expectation with
`on_fail: "warning"`; to drain and confirm the card is idle, use the
`proactive-drain` action.

## Presets: where the keys, TARs and counters come from

An SCP80 action never carries key material.  The PWA sends the **stored
preset's id** with the run; the server resolves it and takes:

- the keyset - the step's `kvn` (1–15) or the preset's first keyset,
- the keys and the counter of that keyset,
- the TAR table with each TAR's **MSL** (Minimum SPI1).

So before a run the matched preset (ICCID) must contain the keyset and, for
every TAR the script addresses, either a TAR entry with its MSL or an explicit
`spi1` in the step.  A step that omits them gets the preset's ISD role TAR as
`tar`, that TAR's MSL as `spi1` and `01` as `spi2`; `kvn` defaults to the
first keyset.

Counter handling: the run starts from the keyset's stored counter and advances
(and persists) its next value after **every** scp80 step the card answers, when
the packet requests a counter check (SPI1 b5b4 ≠ 00, TS 102 225 §5.1.1) - a
refused packet moves the local value forward too.  The local counter therefore
only ever moves up, so a later packet is never below what the card has seen;
consecutive runs continue correctly.

## Actions

```json
{"type": "action", "kind": "…", "params": {…}, "check": {…}}
```

| kind | params | notes |
|---|---|---|
| `envelope` | `event` 0–255, `data` hex (optional), optional `src` | ENVELOPE(Event Download) with raw data; `src` overrides the device-identities source (`82` terminal / `83` network) |
| `event` | `event` (name or hex), `fields` (object) or `data` (form-built hex), optional `src` | semantic ENVELOPE(Event Download): the four server-built events from `fields`, every other event from the editor's `data` (see below) |
| `menu-select` | `item_id` 1–255 **or** `text` + `mode` `exact`/`contains` (+ `case_sensitive: true` for an exact-case match — the default is case-insensitive; the step editor's **Match case** choice writes it), not both | ENVELOPE(Menu Selection); the text is resolved against the card's cached menu - refreshed whenever the card sends SET UP MENU, so it follows the applet's install parameters |
| `file-write` | `path`, `data`, `mode` `auto`/`binary`/`record`, `record` 1–255 | UPDATE BINARY/RECORD |
| `file-read` | `path`, `mode`, `record` | READ BINARY/RECORD; verify with `check.data` |
| `apdu` | `apdu` hex | raw transport, no auto-handler |
| `scp80` | `apdu` **xor** `sp` (optional `source`), `kvn`, `tar`, `spi1`, `spi2`, `format` | secured packet to the TAR; `format`: `compact` (default - the C-APDU verbatim), `expanded` (the `AA`-prefixed Command Scripting template) or `expanded-ae` (the `AE 80 … 00 00` form), TS 102 226 §5.2.1 |
| `status` | `attempts` 1–1000, `interval_ms` 0–10000 | with `attempts > 1` the default SW check is `91??` (poll until a command) |
| `proactive-drain` | `respond`, `first`, `attempts` 1–1000 (default 3), `interval_ms` (default 200), `require` | drain the card's announced proactive commands and confirm it is idle (see below) |

`path` is `/`-separated: `MF` (or `3F00`) or an ADF name/AID first, then FIDs
or file names - e.g. `MF/7F20/6F07`, `ADF.USIM/EF.TEST`.

`file-write` sends a direct terminal-side UPDATE BINARY/RECORD - it does **not**
fire the card's EVENT_REMOTE_FILE_UPDATE (that event reports an update done by
a remote entity through OTA/RFM, TS 102 223 §7.5.9): assert the change with
`file-read` or the REFRESH `files` check.

### Semantic events (`kind: "event"`)

The step editor renders the **same form the Phone tab's send dialog uses**
(`EVENT_FORMS`), for every modelled event - no release gating (a script may
target another card).  The four events the server builds (`0x03`/`0x0B`/`0x12`/
`0x1D`) travel as `fields`: the server validates them at script load and builds
the objects at run time (so the data-connection host clock is fresh).  Every
other event carries the form's built hex as `data` (the editor shows it live
under the form, with the one-ENVELOPE check; the engine validates it and the
single-envelope budget at load).  The `src` device-identities source comes from
the event itself (e.g. MT call and IMS registration are network-sourced) or
from the form's source field; an explicit `src` overrides it.  Both the
`event` and the raw `envelope` action take the same optional `src`.

```json
{"type": "action", "kind": "event",
 "params": {"event": "location_status",
            "fields": {"status": 0, "mcc": "250", "mnc": "01",
                       "lac": "00FF", "cell": "0001"}}}
```

The `event` value may be the code (a hex byte or a number) or one of the name
keywords above; the editor resolves either form to the event - showing the
right form and fields - and saves the hex byte form.

| `event` | fields |
|---|---|
| `location_status` / `0x03` | `status` 0 normal / 1 limited / 2 no service; for normal service `mcc`, `mnc`, `lac`, `cell` |
| `access_tech` / `0x0B` | `tech` (TS 102 223 8.61 coding: 0 GSM, 3 UTRAN, 8 E-UTRAN, 10 NG-RAN, …) |
| `network_rejection` / `0x12` | `reg_type` 0–17, `access_tech`, `cause`; the location object follows the registration group - LU: `lac`, GPRS: `lac`+`rac`, EPS/5GS: `tac` (4–6 hex) + optional `ext_cause`; `mcc`/`mnc`; optional `ext_info_type` (1 CAG ID / 2 NID / 3 RedCap) + `ext_info` |
| `data_connection` / `0x1D` | `status` 0–2, `type` 0–2, optional `cause`, `ti` (hex byte), `datetime: "now"` (host clock, 8.39), `mcc`/`mnc`/`lac`/`cell`, `tech`, `loc_status`, `apn`, `pdp_type` |

`src` overrides the device-identities source (`82` terminal, `83` network);
the editor writes the event's own source into the step (network for MT call /
IMS registration, the form's choice otherwise) - a hand-written step without
`src` is sent as the terminal (`82`).

### Proactive drain (`kind: "proactive-drain"`)

Consume whatever the card announces and leave it idle - at the start, in the
middle or at the end of a script (a leftover command from a previous run must
not derail the next step).  The drain is also the tool for a command **the
previous step left pending** (`91XX`): the runner's *unexpected proactive
command pending* guard does not apply to it - its STATUS poll re-announces
the unfetched command - so a `scp80`/`menu-select` step that answers `91XX`
can be followed directly by a drain.  Each round polls STATUS; a `91XX`
answer fetches
the command and answers it (the first command with `first`, the rest with
`respond` - both `{"result": …}` like an expectation's response).  The loop
ends when STATUS answers `9000` (idle), a non-`91XX` SW appears or `attempts`
rounds are spent; the **final SW is the step's `check.sw`** (default `9000`),
so a still-pending card fails the step and hands the pending command to the
next step.

```json
{"type": "action", "kind": "proactive-drain",
 "params": {"respond": {"result": "ok"},
            "first": {"result": "cancel"},
            "attempts": 5, "interval_ms": 200,
            "require": {"command": "REFRESH", "qualifier": "00"}},
 "check": {"sw": "9000"},
 "label": "serve whatever is pending, leave the card idle"}
```

- An **empty drain passes** (that is the point) - unless `require` is given:
  the step then fails with "nothing was pending".
- `require` asserts **at least one** consumed command matches (`command` name
  or hex type, `ANY` allowed; optional `qualifier`, exact/mask).
- `first` lets a script test the card's refusal path for the first command
  (e.g. `{"result": "cancel"}`) while the rest are answered `ok`.
- Every consumed command is reported (type, qualifier, the TR's SW) and
  logged (`STATUS`/`FETCH`/`CMD`/`TR` lines under the step).

### `check` on actions

```json
"check": {"sw": {"mode": "mask", "value": "91??"},
          "data": {"mode": "exact", "value": "0271…"},
          "por": "ok"}
```

- `sw` - default `{"mode": "exact", "value": "9000"}` (a `status` action with
  `attempts > 1` defaults to the `91??` mask).  A GP INSTALL/LOAD/DELETE
  envelope answers `91XX` - the card announces a proactive command - so give
  those steps the `9???` mask and a `proactive-drain` after them (see
  *Driving a RAM install from a script*).
- `data` - the response data (for SCP80: the inline PoR packet).  The
  `proactive-drain` action does not take a `data` check - assert the drained
  commands with `require` and the final status with `sw`.
- `por` (SCP80 actions only) - `"any"` (default, no check), `"ok"`
  (`response_status == por_ok`), `"none"` (no PoR expected), or an **object**
  `{"status"?, "sw"?, "data"?}` asserting the decoded PoR of this very
  exchange (at least one field; the same fields as the expectation's `por`
  check, `status` accepting `ok` for `por_ok`) - it works for both the inline
  and the SEND SHORT MESSAGE transport.
  Example: `"por": {"status": "por_ok", "sw": "9000"}`.
- A plain hex string is exact; a value containing `?` is a mask.  **A mask
  must have exactly the same length as the actual value** (`?` is a per-nibble
  wildcard) - e.g. `91??` matches `9102`, `027100????` matches a 4-byte
  prefix.

## Expectations

```json
{"type": "expect", "command": "SEND SHORT MESSAGE",
 "qualifier": "00",
 "checks": [{"kind": "por", "status": "por_ok", "sw": "9000"}],
 "respond": {"result": "ok"}}
```

The card must have announced a command (`91XX`) in the previous step - the
runner never polls by itself.  `command` is a name (as shown in the proactive
log) or a hex type; `ANY`/`*` skips the type check.  `qualifier` is the
command-details byte 3 (one byte, exact/mask).

When nothing is pending - or **a different command** is pending - the step
fails at its own `on_fail` level (the default stops the run;
`on_fail: "warning"` warns and continues: the tolerant consume-if-pending
form, and the way to express "the applet either asks X or does Y" - the
mismatched command is still fetched and answered with the step's `respond`).  "Add a `status` action" applies
when the card delivers on poll: `status` with `attempts > 1` polls until a
command appears; it cannot make one appear when the card has none.

| kind | fields | checks |
|---|---|---|
| `text` | `mode` contains/exact, `value`, `case_sensitive` | the **Text string** (`8D`, DCS coded) of DISPLAY TEXT / GET INKEY / GET INPUT |
| `alpha` | `mode` contains/exact, `value`, `case_sensitive` | the command's **Alpha identifier** (tag `05`/`85`, TS 102 223 §8.2, Annex A coded) - distinct from `text` when a command carries both |
| `item` | `id`, `text`, `mode`, `case_sensitive` | items of SELECT ITEM / SET UP MENU |
| `raw` | `mode` exact/mask, `value` | the whole fetched command (hex, exact length needed) |
| `por` | `status`, `sw`, `data` | the PoR carried by a **SEND SHORT MESSAGE** (see below) |
| `sms` | `da`, `pid`, `dcs`, `udl`, `ud` | the TPDU of a SEND SHORT MESSAGE (see below) |
| `files` | `files` (list of path hex strings) or a comma/space separated string | the **File List** of a REFRESH, TS 102 223 §8.18; matched order-insensitively |

`por` needs an SCP80 step **before** the expectation: the TPDU of the SEND
SHORT MESSAGE is decoded with that step's keyset, SPI and counter.  `status`
is the decoded response status name (`por_ok`, `cntr_low`,
`rc_cc_ds_failed`, …; `ok` is accepted for `por_ok`); `sw` is the R-APDU
status word **inside the response payload** - not the envelope's, see
*The three status words* in the authoring section - and `data` the R-APDU
response data (exact/mask); both come from
the decoded response (scripting `AB`/`AF`/compact forms).  An applet's **own
TAR** answers with its application-defined bytes (the response form follows
the command's TAR - see *The three status words*): its secured data is
reported as `data` and no `sw` is decoded - assert such a response with
`data` (the action's `por` object follows the same rule).  The same raw
fallback covers a remote-management reply that cannot be the compact
structure - its command count exceeds the command script that was sent, or
the data is too short for Table 5.1 (TS 102 226 §5.1.2).  A PoR split over
several SMS parts is accumulated across SEND SHORT MESSAGE expectations: put
the `por` check on the step that completes the sequence (intermediate steps
should use `raw` or no PoR check).

`sms` parses the fetched SEND SHORT MESSAGE's TPDU (SMS-SUBMIT only - any other
MTI fails the check): `da` the destination digits as the TPDU carries them
(exact; whitespace and a leading `+` in the script are ignored - the
international flag lives in the TPDU's type-of-number),
`pid`/`dcs` single bytes and `ud` the raw user data (a UDH included) as hex
exact/mask, `udl` the user-data length in decimal (octets, or septets for the
7-bit alphabet - whatever the TPDU carries).  Use it for an applet's own SMS;
the OTA PoR of the preceding scp80 step is what `por` decodes.  At least one
field is required.

### `respond`

Optional - an omitted (or empty) object answers `ok` (`0x00`).  The TERMINAL
RESPONSE follows the TS 102 223 §6.8.0 object order (Command details, Device
identities, **Result**, Duration, Text string, Item identifier, …):

- `result` - a script alias or the two-digit hex value.  The editor offers
  the **full TS 102 223 §8.12.0 list** (`00`–`3F`), labelled
  `<hex> - <alias>` where an alias exists, else `<hex> - <name>`, plus a
  **manual** hex entry for any other value.  With a command selected (other
  than `ANY`) the list is **grouped** by the spec's applicability table
  (TS 102 223 Tables 6.1/6.2/6.3, "proactive commands versus possible terminal
  response"): the command-relevant values first, the rest after - nothing is
  hidden, the manual entry covers everything.  Commands the table does not
  list (SEND SS / SEND USSD / SEND SHORT MESSAGE / GEOGRAPHICAL LOCATION
  REQUEST / End of the proactive UICC session) keep the flat list.  The
  aliases:
  `ok`=00, `partial`=01, `missing`=02, `modified`=07, `cancel`=10,
  `back`=11, `timeout`=12, `refused`=22, `not_understood`=32 (and
  `no_response`=12, kept for compatibility only).
  **v3.23.5 corrected** `refused` (was `03`), `not_understood` (was `04`),
  `modified` (was `06`) and `no_response` (was `22`) to their spec meanings -
  a stored script using one of them now answers with the corrected value.
- `additional_info` - the general result's additional-information byte (a hex
  byte, default `00`): the Result is sent in the general form
  `83 02 <result> <additional_info>`.  TS 102 223 §8.12.2 defines the values
  for the terminal problem (`20`): `00` no specific cause, `01` screen busy,
  `02` busy on call, `04` no service, `05` access control class bar,
  `06` radio resource not granted, `07` not in speech call, `09` busy on
  SEND DTMF, `0A` no NAA active; the network problem (`21`) is NAA-specific
  (`00` = no specific cause).  The editor suggests the §8.12.2 list.
- `text` + `dcs` - the Text string for a GET INKEY / GET INPUT answer.  `dcs`
  uses the spec's recommended codings: `"00"` GSM default alphabet 7 bits
  **packed**, `"04"` GSM default alphabet 8 bits (one octet per character),
  `"08"` **UCS2** (UTF-16-BE).  An empty `text` sends the null text string
  (Length `00`).  A text the selected `dcs` cannot code (a non-GSM character
  with `00`/`04`) is **refused at load** - the error names the coding and
  points at `dcs: "08"` (the run must not fail after the command was
  fetched).
- `item_id` - the Item identifier for a successful SELECT ITEM answer.
- `raw` - extra COMPREHENSION-TLVs appended after the standard objects.

The terminal's own command-specific objects ride with the scripted result
unless `raw` overrides them: a successful PROVIDE LOCAL INFORMATION answer
takes the TR Config **PLI dictionary** value for its qualifier - the entry
or its pre-settled default (v3.23.1; the current date and time for the
date/time qualifier `03`), and a POLL INTERVAL answer
echoes the current interval (TS 102 223 §6.8.4) - the same objects the
terminal's own answers carry.

UCS2 answer to a GET INPUT:

```json
{"type": "expect", "command": "GET INPUT",
 "respond": {"result": "ok", "text": "Пароль", "dcs": "08"}}
```

The `proactive-drain` action's `respond`/`first` use the same shape (the command
type varies per drained command, so `text`/`item_id` apply where the command
carries them).

### BIP commands in scripts

The card's own BIP commands (`OPEN CHANNEL` 0x40, `CLOSE CHANNEL` 0x41,
`RECEIVE DATA` 0x42, `SEND DATA` 0x43, `GET CHANNEL STATUS` 0x44) are answered
by the **terminal**, not by the script: during a run the channels really open,
the data really flows to/from the configured BIP target, and the BIP events
(Data available, Channel status) flow for the channels the card itself opened -
so an applet's own HTTP/BIP conversation completes inside a scripted run.  The
BIP **control** API stays blocked while a run is active (409), like the
terminal's other automatic actions (polling, menu).  The one card-initiated
automatic action that still waits is the **timer expiration** event: a
TIMER MANAGEMENT timer the card armed is not fired during a run (it retries
every 5 s and fires when the run ends) - a deliberate exception to the
"the card's own conversation continues" rule, to review later (v3.25.3).

A step's `respond` overrides the terminal when it carries `raw` TLVs or a
**non-ok result** - the way to script an applet error path:

```json
{"type": "expect", "command": "OPEN CHANNEL",
 "respond": {"result": "refused"}}
```

A plain `{"result": "ok"}` (or no `respond`) leaves the BIP answer to the
terminal; the step log names it (`BIP: the terminal answered OPEN CHANNEL
(0x40)`).

## The two PoR transports (SPI2)

1. **Inline** - the card answers the ENVELOPE `9000` with the PoR in the
   response data.  Verify on the action: `"por": "ok"` and/or
   `"data": {"mode": "mask", "value": "…"}`, or assert the decoded PoR with
   `"por": {"status": "por_ok", "sw": "9000"}`.
2. **PoR-in-submit** (SPI2 bit `20`, e.g. `spi2: "21"`) - the card announces
   a **SEND SHORT MESSAGE** (`91XX`); the PoR is inside its SMS TPDU:

```json
{"type": "action", "kind": "scp80",
 "params": {"apdu": "…", "tar": "B00001", "spi2": "21"},
 "check": {"sw": {"mode": "mask", "value": "91??"}, "por": "none"}},
{"type": "expect", "command": "SEND SHORT MESSAGE",
 "checks": [{"kind": "por", "status": "por_ok", "sw": "9000"}],
 "respond": {"result": "ok"}}
```

If the card announces the SEND SHORT MESSAGE only on a later STATUS poll,
insert a `status` action (`attempts` > 1) before the expectation.

## "No actions" after a trigger

An exact SW check is the assertion: `"check": {"sw": "9000"}` fails if the
card answers `91XX` (a command was announced); the runner also errors on a
pending command the next step does not expect (and drains it with `ok`, see
*Run cleanup*).

## Worked examples

### Event download before an applet action

```json
{"name": "applet event",
 "steps": [
  {"type": "action", "kind": "event",
   "params": {"event": "location_status",
              "fields": {"status": 0, "mcc": "250", "mnc": "01",
                         "lac": "00FF", "cell": "0001"}},
   "check": {"sw": {"mode": "mask", "value": "91??"}}},
  {"type": "expect", "command": "ANY", "respond": {"result": "ok"}}
 ]}
```

The event's default SW check is an exact `9000`; a mask (`91??`) is needed
when the applet answers with a proactive command, which the next expectation
then fetches.

### Menu selection by text (the id varies with the install parameters)
```json
{"name": "applet menu",
 "steps": [
  {"type": "action", "kind": "menu-select",
   "params": {"text": "Settings", "mode": "exact"}},
  {"type": "expect", "command": "ANY", "respond": {"result": "ok"}}
 ]}
```

The text is matched against the card's cached menu, **case-insensitively by
default** (`case_sensitive: true` forces an exact-case match); the cache is
refreshed whenever the card sends SET UP MENU (e.g. after an install +
REFRESH).  If the
script must wait for the menu, add a `status` action and an
`expect SET UP MENU` before the selection.

### RFM update → file change → REFRESH (NAA init + full FCN)

```json
{"name": "applet RFM update",
 "steps": [
  {"type": "action", "kind": "scp80",
   "params": {"apdu": "80E2900000", "tar": "B00001", "spi2": "01"},
   "check": {"sw": {"mode": "mask", "value": "91??"}, "por": "none"},
   "label": "RFM update"},
  {"type": "expect", "command": "REFRESH", "qualifier": "00",
   "checks": [{"kind": "files", "value": "3F007F206F07"}],
   "respond": {"result": "ok"}},
  {"type": "action", "kind": "file-read", "params": {"path": "MF/7F20/6F07"},
   "check": {"data": {"mode": "mask", "value": "AA??CC"}}}
 ]}
```

`qualifier` `00` is "NAA Initialization and Full File Change Notification";
the `files` check asserts the exact set of changed files the applet reports.
For this mode the terminal must **not** reset the card
(TS 102 223 §6.4.7), so the run continues - the following `file-read`
verifies the updated content.

### Driving a RAM install from a script

The RAM APDU list (`POST /api/scp81/gen-install`, or the PWA's *Install from
.cap*) is a sequence of GP commands - INSTALL [for load], the LOAD blocks,
INSTALL [for install], plus a DELETE first when the package is already
loaded.  Drive it from a test script as one `scp80` step per APDU, addressed
to the preset's **ISD TAR** (`000000`; the preset supplies the keys, the
counter and the SPI1 from that TAR's MSL):

```json
{"name": "install applet",
 "steps": [
  {"type": "action", "kind": "scp80",
   "params": {"apdu": "<INSTALL [for load] C-APDU>", "tar": "000000"},
   "check": {"sw": {"mode": "mask", "value": "9???"}, "por": "any"},
   "label": "INSTALL [for load]"},
  {"type": "action", "kind": "scp80",
   "params": {"apdu": "<LOAD 1 C-APDU>", "tar": "000000"},
   "check": {"sw": {"mode": "mask", "value": "9???"}, "por": "any"},
   "label": "LOAD 1"},
  {"type": "action", "kind": "scp80",
   "params": {"apdu": "<INSTALL [for install] C-APDU>", "tar": "000000"},
   "check": {"sw": {"mode": "mask", "value": "9???"}, "por": "any"},
   "label": "INSTALL [for install]"},
  {"type": "action", "kind": "proactive-drain", "params": {}}
 ]}
```

A successful GP step answers **`91XX`**, not `9000`: the card has a pending
proactive command (the re-announced SET UP MENU).  `XX` is that command's TLV
length - `915d` for the 93-byte SET UP MENU, `910b` for an 11-byte PROVIDE
LOCAL INFORMATION, `91b1` for a 177-byte SEND SHORT MESSAGE - so it can never
be pinned exactly.  The default exact-`9000` check therefore fails a step
whose side effect succeeded; give every INSTALL/LOAD/DELETE step the `9???`
mask.  `por` stays `any` by default - assert the remote command's own status
word with `{"por": {"status": "por_ok", "sw": "…"}}` when you want the
stronger check.

The runner refuses to start an action while a command is pending: after
**any** step that answered `91XX` the next step must be an `expect` or a
`proactive-drain`.  The card re-announces the menu after the delete and after
the install, so a drain after those two groups is enough; a drain after any
`91XX` step is always safe.  The drain fetches the SET UP MENU, so the cached
menu (text-based `menu-select`) is current afterwards.

### Incoming data → particular PoR, no other actions

Inline PoR:

```json
{"name": "applet data (inline PoR)",
 "steps": [
  {"type": "action", "kind": "scp80",
   "params": {"apdu": "80E2900000", "tar": "B00001", "spi2": "01"},
   "check": {"sw": "9000", "por": "ok",
             "data": {"mode": "mask", "value": "027100????0102"}}}
 ]}
```

PoR-in-submit (with the transport asserted by the expectation):

```json
{"name": "applet data (SEND SM PoR)",
 "steps": [
  {"type": "action", "kind": "scp80",
   "params": {"apdu": "80E2900000", "tar": "B00001", "spi2": "21"},
   "check": {"sw": {"mode": "mask", "value": "91??"}, "por": "none"}},
  {"type": "expect", "command": "SEND SHORT MESSAGE",
   "checks": [{"kind": "por", "status": "por_ok"}],
   "respond": {"result": "ok"}}
 ]}
```

## Run errors worth knowing

- `SCP80 preset is incomplete: …` - the matched preset has no complete
  keyset; `step N: keyset K is not defined in the preset` - the step's `kvn`
  is outside the preset's keysets.
- `no MSL for TAR … - set it in the Cards tab or pass spi1` - the step's TAR
  has no entry in the preset and the step carries no `spi1`.
- `no proactive command pending` - an expectation ran without a `91XX` from
  the previous step; it fails at the step's `on_fail` level (the check row
  names it).  A `status` action with `attempts > 1` polls until a command
  appears when the card delivers on poll; `on_fail: "warning"` tolerates the
  empty case, and the `proactive-drain` action drains and confirms idle.
- `6A82: … File not found` (or another raised card error) - the step's
  `on_fail` decides: the default stops the run, `on_fail: "warning"` warns
  and continues - the pattern for an **optional** file (`49AC` is documented
  optional: its absence means no menu password).
- `menu-select: no menu item matches …` - the error lists the cached menu; a
  miss on an explicit `case_sensitive: true` names the case-insensitive
  candidates.
- `card verdict: no PoR (the card sent none for SPI2 …)` - an SCP80 operation
  expected a PoR that never arrived (check SPI2 and the transport).

## Run cleanup

When a run ends (an error, a stop request, or an unexpected pending command)
with a command still announced, the runner fetches it and answers **`ok`
(0x00)** and keeps draining while the TERMINAL RESPONSE answers `91XX`
(bounded; each suite member ends the same way, before the next member starts)
- a cancel (`0x10`) is not sent automatically: it tells the card
the user aborted the proactive session, which can push assertive applications
onto an error path and make them queue a further command.  The cleanup is
reported like a normal step (`TR ok …`, `pending REFRESH (0x01) answered with
ok`); a script that wants to test the refusal path answers explicitly (an
expectation's `respond`, or the `proactive-drain` action's `first`).

## Known limitations

- The runner executes one command at a time and never polls by itself; a
  proactive command that arrives only on a STATUS poll needs an explicit
  `status` action (or `proactive-drain` to consume it).
- A `por` check only decodes SEND SHORT MESSAGE commands; the inline transport
  is checked on the action (`por`/`data`).
- An expanded-format command (`"format": "expanded"`/`"expanded-ae"`) has no
  in-packet GET RESPONSE (TS 102 226 §5.2.1.1): if the card answers `61xx`,
  send the GET RESPONSE as a follow-up `scp80` step (its own secured packet,
  same format).
- `files` matches the File List as a set (order-insensitive); duplicate paths
  are kept.
- Semantic `event` actions cover every event the Simulator models: the four
  server-built events (0x03/0x0B/0x12/0x1D) from `fields`, every other event
  from the editor-built `data` hex (the raw `envelope` action stays for
  hand-built data).
