justin 45691334e1 registry: add remaining documented Ford 6.0 PIDs (20 -> 27) 
The initial registry was a curated core; add the rest of the PIDs the
ford-60-pid-hunt workflow surfaced, with honest confidence tags:
- doc:       VGT duty (096D), Fan speed (099F)
- tentative: Injection timing (09CC, *10/64 not /10), PCM battery (1172),
             fuel-pump duty (1672), fuel level (16C1, uncalibrated),
             mass-fuel-desired (1411, raw only -- no verified GPH formula)
Add VGT to the driving preset. Tests still pass.

Tier reminder: 'verified' = multi-source/standard or truck-confirmed; the
on-truck-confirmed subset remains ICP/EBP/MAP/BARO/EOT/gear/TSS + FICM_M.

justin 4589904b97 P1: PySide6 + pyqtgraph GUI shell (PID browser + live overlay plot) 
First graphical frontend on obdcore. Cross-platform (Win/mac/Linux).

- gui/controller.py: owns link/registry/store/scheduler; subscribe == poll ==
  plot; per-PID rates (ICP/FICM/RPM fast); optional CSV recording.
- gui/main.py: connection bar (port dropdown via find_ports, baud, Mock,
  connect), left PID browser grouped by system with live values + confidence
  badges + checkboxes, central pyqtgraph overlay plot with legend, Normalize
  (% of range) toggle for mixed-scale PIDs, Crank/Driving/Vitals presets,
  10Hz refresh reading the store off the acquisition thread.
- run_gui.py launcher; requirements-gui.txt.
- store.py: lock Channel push/series (GUI reads while scheduler writes).
- docs/gui-p1-preview.png: validated render (mock crank, ICP ramp to 540).

Validated headless (offscreen Qt): connect(mock) -> crank preset -> ICP
streams past 500 -> normalize -> uncheck removes curve -> clean disconnect.
obdcore tests still pass after the locking change.

justin 6bee9c0d7f Scaffold obdcore (headless acquisition core) + ARCHITECTURE.md 
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.
