ui: translate the RAM operations hint

The data-l10n key for 'RAM operations perform atomic GlobalPlatform commands over SCP80. Card keys are taken from the saved preset.' was missing from LANG_RU, so the hint stayed English. SW cache v127 -> v128.

catarrh	2494e04984	ui: clear stale RAM status on op change, remember the card preset - ramOpChanged() now clears the previous execution status (result line, steps, explorer, progress) only when the Operation value actually changes, so switching Explore -> Install Package no longer shows the old 'Partial - ELF Modules: no data' until Execute; re-entering the RAM subtab still preserves the last result - ramClearResults() also hides the progress caption - the Card preset dropdown no longer resets to the placeholder after every executed operation (ramSaveCntr -> ramRender rebuilt it) or on subtab re-entry: ramRender keeps the current/remembered index, ramApplyCard and ramExecute remember the selection for the session, and cardsRemove keeps _ramCardIdx aligned via ramCardIdxAfterRemove - tests: op-change clearing, selection preservation across rebuilds, pick/execute remembering, index bookkeeping; SW cache v126 -> v127.	2026-09-12 23:20:26 +03:00
catarrh	b49e6728b4	ui: translate SCP80/RAM explorer labels, buttons and result strings The RAM explorer HTML is generated after load, so its data-l10n sections and Delete/Delete All buttons stayed English until a language switch, and the memory/AID/lifecycle labels were hardcoded with no key at all. - ramRenderExploreHtml() now builds every label and button with t() (reusing the existing Delete/Delete All/heading/AID keys and wiring the three previously-unused Application/Instance, Load File and Module AID keys); new RU keys cover Applications:, Free NV:, Free Volatile:, AID:, Lifecycle:, Privileges:, SD AID:, Implicit sel:, Version: and (none) - the explorer dataset is cached in _ramExplorerData and re-rendered by refreshDynamicI18n() on language switch (cleared on op change/results reset) - RAM flow strings localized too: Partial/OK summaries, error labels (Memory/ISD/Apps/ELFs/ELF Modules/no data), GET DATA progress, delete confirm/labels, install alerts/progress/steps and Error: - tests: ram.test.js asserts every explorer label/button goes through t() and the (none) placeholder; SW cache v125 -> v126.	2026-09-12 23:07:28 +03:00

catarrh	8459040856	ui: auto-refresh the proactive log and STK menu state The proactive command list only re-rendered on tab/pill switches, so new fetched commands (background STATUS polling, menu traffic) stayed invisible while the Phone view was open. - /api/status now exposes proactive_seq (_PROACTIVE_ENTRY_ID, monotonic and not reset with the log), so the existing 2s status poll detects changes with no extra request; pysimCardStateUpdate() re-renders the log when the sequence changed and the Phone/Phone view is visible - the 5s backend timer no longer fetches the log (it was discarded) and now uses the already-fetched stk-status: when active/pending changes while the Phone tab is visible, stkCheckMenu() refreshes the menu button without a tab switch - pysimProactiveLogRender() keeps its scroll position and only shows Loading... on a first/empty paint - tests: proactive seq + STK signature helpers and poll-driven render behaviour in card_state.test.js; SW cache v123 -> v124.	2026-09-12 22:22:55 +03:00

catarrh	2a559371ae	ui: keep the selected file in state, drop the File: title line The File: EF.DIR [LF] line doubled as the selection store: pysimFsClickFile wrote a formatted display string there and pysimFsRead/Save parsed it back (stripping '✗ ' and ' [TYPE]'). The pane now keeps the name in pysimFsSelected, the redundant title is gone (FID/type/size/FCI remain in the info block), and the dead pysimFsSelect() plus the unused 'File:' RU entry are removed. Read/Save still re-select on the server first: pySim's current selection is a shared cursor that tree expansion, scans and commands move, so it cannot identify the file shown in the pane. SW cache v121 -> v122; structural test updated.	2026-09-12 22:12:25 +03:00
catarrh	e0e86e31af	ui: drop the Decoded FCI caption in the file manager info block The decoded FCI items now follow the FID/type/size line directly; the snapshot detail view keeps its caption. Test updated to assert the caption is absent; SW cache v120 -> v121.	2026-09-12 21:59:41 +03:00
catarrh	2ec7a2d6c0	ui: show FID, layout and decoded FCI in the file manager detail pane - selecting an EF now renders an info block between the File: title and the contents: FID, file type, size, record length/count (nulls skipped) followed by the decoded FCI via the existing profilerFciPreviewItems() decoder (no raw hex), matching the snapshot detail view - pysimFsInfoHtml() is pure and reused by pysimFsClickFile(); the [LF] shorthand stays in the title; custom files get the same metadata from the temporary select probe - tests: pysimFsInfoHtml in profiler.test.js (full response, missing fci_hex, skipped nulls) and a structural check for #pysim-fs-info; help EN/RU and READMEs updated; SW cache v119 -> v120.	2026-09-12 21:54:06 +03:00
catarrh	26f0063696	ui: reword the custom files hint - EN: Custom files are added in file manager tree and included in card scan. - RU: Пользовательские файлы добавляются в менеджер файлов и учитываются при чтении карт. - SW cache v118 -> v119.	2026-09-12 21:47:23 +03:00
catarrh	ddc6cb8f9d	fix: parent-scoped file selection; never mutate the pySim model pySim's lchan.select() resolves names against global selectables (self + parent chain + MF children + applications) and falls back to probe_file(), which blindly SELECTs an unknown FID and permanently injects a dynamically named DF.XXXX/EF.XXXX into the running filesystem model. Probing a whole tree or scanning a snapshot with custom files therefore polluted the model, made tree branches show children of the wrong object, and could persist phantom files into snapshots. - server: new _select_with_parent()/_select_path() walk the requested parent path (new parent_path field, parent_sel kept as legacy fallback) strictly through the model and call lchan.select_file() only; model-unknown 4-hex segments are probed only with allow_probe and the temporary child pySim adds is detached again via the cleanup callable that the four handlers (/api/tree\|select\|read\|write) now run in a finally block - frontend: getParentPath() builds the segment chain (MF, ADF names, FIDs) and all tree/select/read/write bodies plus the snapshot/profile walker send parent_path; allow_probe is set only for custom files; the blind retries in the file manager were dropped - tests: tests/test_select_scope.py (duplicate-FID resolution, no APDU for unknown non-custom files, probe+detach, model unchanged); fs_load/fs_probe assertions for parent_path and allow_probe; docs/api.md and AGENTS.md document the contract; SW cache v117 -> v118.	2026-09-12 21:45:57 +03:00
catarrh	85a66af7a5	ui: hide, don't clear, children of non-selectable DFs - pysimFsLoadChildren failure now only marks exists=false and re-renders; loaded children stay in the node and are hidden by the renderer (red cross, no toggle, no (empty)), so a failed DF is re-attempted on the next probe/refresh instead of being short-circuited - dropped the parent_sel-less /api/tree retry: error payloads now carry exists:false, so it doubled requests for every absent DF and re-selected the same FID without its parent (pySim probe_file fallback) - probe walks strictly on exists===true and never collects files under a non-existing DF; no longer clears children on a failed EF select - tests updated: single request per failed load, children untouched, 200 exists:false marks absent without retry, render hides stale children, probe never fetches/selects them; SW cache v116 -> v117.	2026-09-12 21:23:31 +03:00
catarrh	92271d6726	ui: probe-all-files walk and honest file tree coloring - pysimFsLoadChildren now treats {success:false,error} (and any error payload) as a failed listing: absent DFs/ADFs render as a red cross without an expand arrow instead of silently opening empty; the /api/tree 500 body also carries exists:false for shape consistency with /api/select - an expanded directory with zero children shows a gray (empty) placeholder - new Probe all files button (data-needs=card) in the tree header: walks the whole model tree from MF, verifies every DF/ADF via /api/tree and every file (incl. custom entries) via /api/select, skips subtrees of absent dirs, shows N/total progress, toggles to Stop, and reports present/absent counts with elapsed time; results colour the current tree only - tests: fs_load (error/retry/empty), fs_render (red cross, (empty)), fs_probe (flags, absent-dir skip, custom files, stop, summary); html structural check; help EN/RU, READMEs, AGENTS updated; SW cache v115 -> v116.	2026-09-12 21:14:09 +03:00
catarrh	4598a70db2	ui: edit/delete buttons for custom files - each row now shows Edit and Delete buttons (same styling as the profiler list buttons) instead of the red X glyph - Edit reloads the entry into the top form: the Add button becomes Save (data-l10n updated too) and a Cancel button appears; submit updates the entry in place, recomputing fid/parentFid and excluding the edited row from the duplicate-path check - Delete removes without confirmation; deleting the row being edited cancels the edit and an earlier deletion shifts the edit index - pysimCustomAdd renamed to pysimCustomSubmit; tests for the whole flow; SW cache v114 -> v115.	2026-09-12 20:14:24 +03:00
catarrh	82fb2c8800	ui: move the Profiler tab next to SCP80 - top-level tab order is now Remote APDU, SCP80, Profiler, Card reader, Phone simulator; the profiler view moved with its button so the DOM order matches the tab strip - docs (help EN/RU, READMEs) and the tab-order test updated; SW cache v113 -> v114.	2026-09-12 20:09:47 +03:00
