Infer the card's ETSI release from its installed uicc.toolkit version
The explorer's card-resources block now names the card's ETSI release, using the same mapping as the CAP analysis (capmem.ETSI_TOOLKIT_RELEASE: uicc.toolkit version -> REL-N, basis in brackets; the live card's 1.12 -> REL-15/16/17). The table is mirrored in the PWA (drift-guarded by tests/test_cap_memory.py, like JC_FRAMEWORK_SDK); the version comes from the expanded registry's CE tag and degrades to the version hint when the listing has none; SIM-only cards (no uicc.toolkit) get no label, the same rule as SIM-only CAPs. - cardEtsiRelease(elfs) (pure) + UICC_TOOLKIT_AID / ETSI_TOOLKIT_RELEASE in the PWA; rendered after the free-memory lines with a tooltip naming the basis. - Tests: helper vectors (1.12/1.11/1.5, unknown version, versionless, SIM-only), the rendering guard, and the table/AID drift guard. - Help EN/RU; sw cache simple-v354.

<p class="text-sm mb-3">A “Verify vs pySim” button cross-checks the assembled packet against pySim’s reference <code class="font-mono text-sm">OtaDialectSms.encode_cmd</code>. A “Send to Card” button delivers it via SMS-PP-DOWNLOAD ENVELOPE (when connected to the server). The 2-byte CPL prefix is transmitted whenever the packet is ciphered or carries RC/CC/DS (it is part of their input) and whenever the packet is concatenated; a single unprotected SMS keeps pySim’s CHL-first form (TS 31.115 Table 1 NOTE). Under the packet field the app reports its size and how many SMS it takes; a packet that does not fit one SMS is sent as a <strong>concatenated</strong> download (TS 31.115 §4.3) — the packet is split into SMS user-data parts (first SM 132 octets, following ones 134; the first one additionally carries the concatenation and CPI information elements) and the segments are sent in order. More than 5 segments is refused, that being the practical limit of the card’s concatenation buffer. The returned Proof of Receipt is decoded and shown as a PoR status line (status, TAR, counter, raw PoR); the last command’s status word and response data are filled into the <strong>R-APDU parser</strong> panel, and a successful PoR advances the replay counter (when SPI1 carries a counter check — b5 b4 ≠ 00; without one no counter is advanced or saved) and clears the packet. A <strong>low-counter</strong> verdict (<code class="font-mono text-sm">cntr_low</code>, or a warning ENVELOPE answer that still carries such a PoR) is <em>not</em> recoverable by retrying: every SCP80/RAM operation stops immediately. The card never reports its counter (the PoR’s CNTR field is a copy of the packet’s), so the notice offers a bounded <strong>Sync counter</strong> probe — a read-only command with increasing counter values (doubling steps, a 32-bit ceiling, at most 40 packets) until the card accepts one, then accepted+1 is stored — and a <strong>Go to preset</strong> button for raising the counter by hand; nothing else is written automatically.</p>

<p class="mb-2">Delivers Remote Application Management operations as SCP80 secured packets via SMS-PP-DOWNLOAD ENVELOPE. The card must support SCP03 (AES or 3DES). A saved card preset from the <strong>Cards</strong> tab provides the SPI, keys, TAR, and counter (RAM uses the preset's <strong>ISD TAR</strong>, <code class="font-mono text-sm">000000</code> by default). The <strong>Keyset</strong> selector next to the preset selector picks the keyset whose keys and counter the operation uses. It is disabled until a card preset is selected. The start button stays disabled until a card preset and one of its keysets are selected. The <strong>Format</strong> selector pins the remote command format: <strong>Auto (detect)</strong> probes the read-only GET STATUS command compact and in both expanded codings and keeps the first that the card executes, <strong>Compact</strong> sends the bare C-APDU, and <strong>Expanded (AA, definite length)</strong> / <strong>Expanded (AE 80, indefinite length)</strong> wrap it in the TS 102 226 §5.2.1 scripting template (both execute on the live ISD; a template whose declared lengths do not match its body draws a Bad format TLV, which the operation shows as the step failure). The listing and registry queries follow that format: compact listings keep the chained GET RESPONSE, while an expanded run sends the same P2=00 queries wrapped and unchained (the reference TCA loader’s form, Le=’00’ returns the listing directly), and a registry query the card refuses in the current format is retried in the other formats — the report names the one that served it.</p>
