Both scripts now resolve REPO_DIR as their own directory (repo root)

requirements.txt now references the upstream GitHub repo pinned to
commit c30dc37 (the last upstream commit before our fix), so the source
is portable and not machine-specific.
install.sh applies cariad-hybrid-auth-fix.patch to the installed
site-packages after pip runs, using `patch -N` so it is idempotent on
repeat installs. The patch file is checked in to the repo so install.sh
can always find it.

Switches the VW API backend from carconnectivity + connector-volkswagen
to volkswagencarnet (local fork with the cariad-hybrid-auth-fix patch
applied), fixing authentication against the current CARIAD BFF endpoints.
- requirements.txt: point at local volkswagencarnet git repo via
git+file:// URL (editable path no longer needed now the patch is
committed there)
- we_connect.py: rewrite around the async volkswagencarnet Connection
class; a persistent asyncio event loop held in _Session lets the rest
of the code stay synchronous
- data_model.py: remap all extractors to volkswagencarnet Vehicle
properties and Paths constants; output shape preserved so
apply_procedural and the GUI client continue to work unchanged
- collect.py: swap carconnectivity error import, drop
TemporaryAuthenticationError (no equivalent), fix vehicle.vin.value →
vehicle.vin

- Add extract_windows() and register 'windows' in ALL_DOMAINS
- Remove windows extraction from extract_doors; no more double keys
- extract_windows also captures the overall windows.open_state

- Don't store attributes whose .value is None; avoids spurious "None"
strings in the snapshot (lock_state, open_state were unset)
- Flatten the structure: overall lock_state/open_state now live directly

- Give vehicle.windows its own try/except, independent of vehicle.doors
- Capture doors.open_state (overall open state) which was missing before

DashboardTab.update() had no else-branch for non-dict, non-physical

vehicle.state and numeric fields like position.lat/lon were silently

server/install.sh was broken after moving into server/: SCRIPT_DIR now

Covers API reference, diff/delete-delta encoding semantics, round-trip
guarantee, wire format usage, test overview, and bug history from the
recent aliasing crash and empty-dict pruning fixes.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Bug 1 (crash): jay_merge_delete iterated _new.items() while _old (which
aliases _new sub-dicts due to jay_diff_rev's side-effect writes) was being
mutated. Fixed by snapshotting with list(_new.items()) before iteration.
Bug 2 (wrong round-trip): When new has an empty dict {} at a location where
old had a non-empty dict, jay_merge_delete incorrectly pruned the now-empty
parent key. Root cause: jay_diff_del stored the full old sub-dict in the
delete delta for both "key absent from new" and "key present but empty in
new", making them indistinguishable at merge time.
Fix: jay_diff_del is now a standalone recursive function that stores None
for dict keys entirely absent from new (sentinel for "delete entire key")
vs a sub-dict of specific sub-keys for partial deletions. jay_merge_delete
no longer prunes empty dicts; None (or any non-dict value) in the delta is
the explicit signal to remove the parent key.
Also adds:
- tests/data/ — copy of 25 real JSON log files for integration testing
- tests/test_jay_diff_real_data.py — 2028 parametrised round-trip tests
over 675 real vehicle snapshots; exposed and confirmed both bugs above

Move the inline assertions from jay_diff.py into tests/test_jay_diff.py
as proper pytest functions, grouped by function under test. Add corner
cases for numeric/bool/None/list values, completely different structures,
empty containers, deep nesting, type changes (dict↔scalar), and
parametrised round-trip tests (diff→merge produces new).
Two bugs fixed during the exercise:
- jay_diff_rev: guard against _old being a non-dict (type change from
dict to scalar caused TypeError on item assignment)
- jay_merge_delete / jay_merge_update: already fixed in previous commit;
covered by new tests

Flatten the snapshot structure so each domain maps directly to its
fields rather than mirroring the old WeConnect status-object nesting.
New domains: electric_drive (range, battery/SOC/temps, odometer),
connectivity, vehicle, position, doors — replacing the old readiness,
parking, access, and measurements domains. Update apply_procedural
paths and collect.py defaults accordingly.

Replace the weconnect library with carconnectivity and
carconnectivity-connector-volkswagen. The connector is configured via
a dict passed to CarConnectivity(); startup()/fetch_all() replace
login()/update(). All domain extractors in data_model.py are rewritten
for the new object model (vehicle.charging.*, vehicle.get_electric_drive(),
vehicle.climatization.*, etc.). Remaining time fields are now derived
from estimated_date_reached DateAttributes. Battery temperatures are
read directly in °C (no Kelvin conversion). Auth error handling drops
the manual re-login since the connector manages token refresh internally.

The outer loop in DashboardTab.update assumed a 3-level hierarchy
(domain → object → fields). Procedural fields sit one level higher
(domain → field directly). Check _is_phys() first and render value /
unit into the correct columns instead of descending into the dict and
showing 'value' and 'unit' as separate rows.

server/data_model.py:
- apply_procedural(record) — stub function; add computed fields to the
proc dict inside and they appear under record['procedural'] in every
record stored and broadcast.
- _get(data, *keys) — safe nested dict accessor for use inside
apply_procedural.
collect.py:
- New snapshots: apply_procedural() called after collect_snapshot(),
before appending to the store and broadcasting.
- Preloaded 24-h history: guarded apply (skip if 'procedural' already
present) applied after load_last_24h_records().
- Current-day store loaded from disk: same guarded apply after
load_store(), so legacy records sent to clients are enriched on the fly.

Track a _needs_autozoom flag per plot. Set True at startup, on
reconnect (clear_data), and when a trace is added or removed. In
_redraw, when the flag is set and visible data exists, fit the Y range

updates leave the user's manual Y zoom undisturbed.

Add PlotTooltip — a frameless child widget that appears next to the
mouse cursor whenever it moves over a plot. It lists each active trace
with a colored bullet, short name, and the nearest y-value (unit
appended). The tooltip is repositioned on every mouse-move event and
clamped to stay within the plot widget bounds. Hidden on mouse-exit and
on clear_data (reconnect).

When _diff contains none of the jaydiff keys (update, update_add, add,

jay_merge_full/jay_merge_update mutates _state nested dicts in place.
The previously emitted dict(_state) was a shallow copy sharing those
nested dicts, so background-thread merges retroactively corrupted
already-emitted snapshots: timestamps were correct (strings are
immutable) but Y values all converged to the latest record's values.
Fix: emit copy.deepcopy(_state) so each snapshot is fully independent.

Server (collect.py --diff):
- History burst: first record sent full, subsequent as jay_diff_full diffs
- Live broadcast: each snapshot diffed against the previous one
- Diff payloads tagged with "_diff": true
Client (client.py --diff):
- Reconstructs full state via jay_merge_full before printing
GUI (Connector tab "Diff mode" checkbox):
- TcpReader.connect_to() accepts diff_mode; maintains _state dict
- Merges incoming diffs before emitting to Dashboard/Plot
- Checkbox state persisted to plot_settings.json
Both sides default to off; must be enabled consistently on server and client.
utils/__init__.py added so utils.jay_diff is importable as a package.

Replace direct _redraw() calls in PlotTab.update() with a 100 ms
single-shot QTimer. During a burst of incoming records (e.g. 500

per record (~4000 pyqtgraph redraws avoided).

All are now read from the credentials JSON (interval_s, host, port,

Previously load_today() was only called if in-memory records were empty,
