- the timeline's Δ glyph became a **Details** button, and it now appears on
Update rows too (not just card-side changes); EN "Changed (card)" ->
"Changed on card", RU "Изменено (картой)" -> "Изменено картой"
- the details modal shows the affected unit — the whole file, or the single
record that changed — **before and after** the change as hex views (16 bytes
per row, ASCII column, never-observed bytes as `--`), with the bytes that
changed and the bytes the operation *first observed* highlighted in two
different colours, plus the changed/new byte counts and the APDU reference;
the old before/after byte table is gone
- `GET /api/sessions/<id>/files/image?key=…&change=…` returns those two views
(segments with offsets) plus the change's metadata; the images are
reconstructed from the current image by undoing the later changes
(`FileTracker.change_images`), so nothing is duplicated per event — every
value change is an event, hence the values are exact (a byte only first
observed later can appear as known in both views)
- tracker: change events carry `observed_ranges` (bytes that were unknown
before the operation) next to `ranges`; an update that only observes new
bytes now records an event (so it can be inspected); record-file ranges are
in-record byte offsets (the record number stays in its own field), which the
previous "record number as position" could not express for a hex highlight
- tests: change-images reconstruction (before/after per event, later changes
undone, records isolated, observation-only events, unknown gaps), the image
endpoint (200/404/400), and Node tests for the hex-image helper (highlight
classes, unknown gaps, ASCII, row limit) and the modal rendering
- v2.4.0; SW cache simtrace-analyser-v65
- new `simtrace_analyser/filetrack.py`: a single-pass tracker over a
session's decoded messages, keyed by (DF, FID) and trace-wide (resets only
wipe the per-channel selection): counters (`select`/`read`/`update`,
successful operations only), a sparse image of the observed bytes
(transparent files by offset, record files per record number) and the
change log
- changes: **device** = an UPDATE seen in the trace (applied to the image,
`no_change` flags a provable no-op); **card** = a READ whose bytes differ
from the image on bytes already known (logged at the surfacing read with
the changed ranges and the before/after hex; never-seen bytes just fill
the image, they are an observation, not a change)
- SFI-addressed accesses join the same entry as path/FID ones: the SFI ↔ FID
relations come from the normative tables and from every surfaced FCP `88`
DO (including the spec's "SFI = 5 LSBs of the FID" rule when the DO is
absent); an SFI used before its relation is learned stays provisional and
merges into the resolved entry
- the DF identity follows TS 102 221 §8.4/Table 8.2: `selected_df_fid()` now
resolves an EF path selection to its parent DF and returns `aid:<hex>` for
applications selected by an unknown AID (named from EF.DIR when the trace
surfaced it); `Database._decode_rows` gained an `on_message` hook and
`track_files()`
- `GET /api/sessions/<id>/files`: the operation timeline, the per-file
counters/coverage/change log, the SFI relations and the AID labels
- PWA: the side panel's Map/Stats tabs became a view selector (Map / Stats /
Files); the Files view is a timeline of Read / Update / Changed (card) rows
(colour-coded, the same file names as the Map view), a row click jumps to
the APDU (loading the pages it needs) and a card-change row's Δ opens the
changed ranges with the previous and the new bytes; EN/RU
- bounds: the image freezes past 64 KB of observed bytes per file, the change
log keeps the last 1000 events per file (counters keep counting)
- tests: tests/test_filetrack.py (counters, resets, channels, image/diff
semantics, record files, SFI resolution and the provisional merge, EF.DIR
labels, caps, the endpoint) and Node tests for the Files-view helpers and
wiring
