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).
- docs: api.md's optional-`cntr` contract + seeding notes on every endpoint,
help EN/RU 3.1. Tests: 822 frontend + 734 Python; sw cache simple-v393.
- the ADM input capped the key at 8 chars, but the server's _verify_adm
takes 4-16 hex digits (padded to 8 CHV bytes) and the old input had no
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.)
- dropped the now-unused cardsRoleMsl helper and its test references.
- docs: the ADM is documented as 4-16 hex digits (help EN/RU, api.md,
AGENTS). sw cache simple-v362.
Tests: 665 Python + 784 frontend green; the whole inline PWA script
syntax-checked.
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.
Gating: the SCP80 "Send to Card", the RAM Execute and the TAR-probe Execute
buttons carry `data-needs-keyset`; pysimApplyAvailability() disables them
(with the hint "Select a card preset and its keyset" when the card itself is
fine) unless the view's preset is selected and the form's keyset number is one
of its keysets - `spKeysetStartReady`, the same rule the click-time guards
enforce, which stay as the last line of defence. spKeysetSync() refreshes the
gate on every preset/keyset change, and the KIc/KID index selects now call
spKeysetSync() so the keyset selector follows a manual index change too.
Version 3.9.0: server VERSION, pyproject.toml and the PWA header; sw cache
simple-v346; the workspace AGENTS gains its v3.9.0 history entry.
Tests: indicator.test.js drives the gate (no preset -> disabled with the hint,
an undefined keyset -> disabled, a matching keyset -> enabled) and guards the
three buttons' attribute; the cards/keysets/ram sandboxes stub
pysimApplyAvailability. Help EN/RU notes the disabled start buttons.
A keyset only exists inside a card preset, but the SCP80/RAM/TAR keyset
selectors stayed enabled with no preset selected - showing either
"— no keyset —" or a stale "Keyset N — not defined in the preset" entry left
over from an earlier preset. spKeysetSync() now disables the selector and
reduces it to a "— select a card preset —" placeholder whenever its view has
no preset selected, and re-enables/populates it as soon as one is.
Clearing the preset dropdown ("— Select card —") also refreshed nothing:
cardsApply() returned before the sync, so the stale keyset list stayed; it now
syncs the selectors (and the preset warning) on the empty selection too.
The three selects get disabled:opacity-40 disabled:cursor-not-allowed (the
rules are already in the compiled style.css). Tests: keysets.test.js covers
the disabled/cleared state and the re-enable plus a cardsApply source guard;
cards_form.test.js and cards_counter.test.js gain tarPresetIdx in their
sandboxes. Help EN/RU and both AGENTS files; sw cache simple-v343.
Autoselection normally keeps the SCP80/RAM preset in step with the card, so
the mismatch is easy to miss. Both views now carry an amber banner above the
preset selector (the existing warning style - no new Tailwind classes):
- the equipped card matches no preset: "The equipped card <ICCID> does not
match any card preset - the selected preset may belong to another card.
Add it in the Cards tab (From card)"; with no presets at all the banner says
so instead;
- a preset is selected but it is not the equipped card's: a softer line naming
the matching preset ("check that its keys and counters belong to this card").
`spPresetWarning(iccid, presets, selectedIdx)` is pure (unit-tested with the
ICCID forms the store accepts: digits, spaced, raw EF hex), `spPresetWarningRender`
fills both banners and runs on every card-state poll, preset load, preset
selection and page init. No card session or an unreadable ICCID shows nothing
(the card-iccid gating already explains that state); the banner warns only -
it never blocks a send (preparing a packet for another card stays possible).
Tests: frontend/tests/preset_warning.test.js (5), the card-state/preset
harnesses stub the DOM-bound renderer. sw cache simple-v336.
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).
Docs/help/AGENTS updated; sw cache simple-v335. Tests: 610 Python (store
keysets, endpoint refusals, the counter landing in the right keyset) and 726
Node (keysets.test.js plus the updated harnesses).
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.
652 frontend / 499 Python green; version 3.6.21.
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.
608 frontend / 492 Python green; version 3.6.4; sw simple-v277.
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.
