Rename: the app is vehicle-agnostic, so 'ford-obd' was wrong. Rebranded all
code/docs/profile authors to OBDash; Gitea repo renamed justin/ford-obd ->
justin/obdash (remote + description updated). Ford the make and the
ford-6.0-powerstroke profile are unchanged (that vehicle really is a Ford).
Multi-axis upgrade (per request):
- MultiAxisPlot now gives each METRIC its own Y axis, each axis colored to
match its line; the primary metric owns the LEFT axis, others stack right.
- Click a line to promote it to the left axis (sigClicked -> set_primary).
- Cleaner teardown (no removeItem warnings); axis label no longer doubles the
unit; Normalize round-trips.
Validated headless: colored per-metric axes, promote-to-left, gauge view,
normalize toggle, profile switch; obdcore + diagnostics tests pass.

The stack is portable by construction: PySide6/pyqtgraph/numpy/pyserial all
ship wheels for all three OSes (incl. Apple Silicon); obdcore has no
OS-specific code; the terminal dashboard's only platform code is guarded
(os.name=='nt' vs termios for POSIX = macOS+Linux).
- ARCHITECTURE.md: Cross-platform section -- portability rules (list_ports
only, pathlib, no shelling out, platformdirs for config), the three per-OS
seams (CH340 driver, PyInstaller per-OS packaging, Gatekeeper/SmartScreen).
- README: Setup now covers Windows (CH341SER), macOS (CH34xVCPDriver), Linux
(in-kernel ch341 + dialout group) instead of Windows-only.
No code changes; obdcore tests still pass.

Foundation for the PySide6 + pyqtgraph Windows GUI, shared with the terminal
tool. Pure data/IO -- no Qt, no curses.
obdcore/
link.py ElmLink -- ELM327 serial (Mode-01/22, ATRV, DTC read/clear)
mock.py MockLink -- synthetic crank for tests + GUI dev (no truck)
registry.py PidRegistry (verified Ford 6.0 PIDs + confidence) + DtcDatabase
scheduler.py PollScheduler -- prioritized round-robin polling, dead-PID park,
derived channels; tick() is fake-clock test-drivable
store.py TimeSeriesStore (ring buffers + min/max) + CsvRecorder/replay
Design centers on the ELM327 bandwidth limit (~7-15 reads/sec): the active
view subscribes PIDs at chosen rates; acquisition runs off the UI thread;
the GUI only reads the store. FICM_M (09D0) promoted to verified after the
2026-06-30 on-truck crank read (48.0V, intermittent).
tests/test_obdcore.py: decoders vs real truck bytes, crank ramp + peak,
derived BOOST, dead-PID park/revive, record/replay roundtrip -- all pass.
ARCHITECTURE.md: layers, data model, GUI plan, 6.0 stock-PID limits
(no EGT/oil-PSI), feature backlog, P0-P5 roadmap.
