The plain "Send to Card" path refreshed the whole preset right before
sending (spRefreshFromPreset -> cardsApply -> cardsApplyFields) and
re-applied the preset's slot TAR - so a TAR typed for a push/link trigger,
an applet OTA message or the HTTP OTA admin params was silently replaced by
the preset's ISD TAR (the pack buttons for those sources deliberately leave
the TAR manual; the help even said so).
- spRefreshFromPreset(selId, keepTar): the plain send passes keepTar, so
the form's TAR survives; the counter, keys and SPI are still re-read.
- selecting a card preset, ramApplyCard and the chain packs still set the
TAR; the RAM operations keep the preset's ISD TAR by design.
- spParams()/getRamSpParams() normalise the TAR (strip/upper/pad to 6);
only the preview padded before, a short TAR went to the server raw.
- help EN/RU clarified, cards_counter/ram tests updated, sw simple-v294.

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.

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.
