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 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)
and the updated PWA tests. sw cache simple-v334.
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.
607 frontend / 488 Python green; version 3.6.3; sw simple-v276.
- the ADM badge gains a trailing key glyph (ADM ✓ ⚿ / ADM ✗ ⚿) when the
preset matching the equipped card's ICCID carries an ADM key; the four
tooltip states cover key/no-key x verified/not-verified
- new gray SCP80/SCP81 markers after ADM, shown only when that preset has
all SCP80 fields (KIc/KID, SPI1/SPI2, counter, KIc/KID keys) or the SCP81
PSK pair filled in; hidden without a card session, a matching preset or
the fields, never color-coded
- cardsScp80Complete/cardsScp81Complete/cardsAdmPresent/cardsMatchedPreset
helpers; cardsRender reuses the SCP81 predicate
- tests: ADM four-state badge, marker show/hide, predicate whitespace
handling, header markup order; help EN/RU updated; SW cache simple-v201
- the SCP80 fieldset gains ISD TAR (000000), UICC TAR (B00000) and USIM TAR
(B00001), prefilled with the spec defaults; empty stored values mean the
default for that target (cardsTarValue)
- ADM field between "From card" and "Add", stored in the preset for later
use by the file manager (placeholder ADM (optional), spaces stripped)
- packing a chain selects the preset TAR for its target: RAM/GP -> ISD,
SIM RFM -> UICC, USIM RFM -> USIM (spec default without a preset);
_spTarKey keeps the target when the card preset is picked afterwards,
RAM card selection forces the ISD TAR
- USIM RFM 'from current DF' labelled (ADF.USIM); the list TAR column shows
all three values; help EN/RU updated
- SW cache simple-v199; new cards_form.test.js + html markup guards
