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
