Vehicle data is now DATA, not code. PIDs/scaling/DTCs/presets live in profiles/*.json; the app loads them at runtime, so it works across vehicles and others can contribute profiles (open source). Core: - obdcore/formula.py: safe AST evaluator for scaling formulas (A/B/... byte vars, Torque/FORScan convention). Only arithmetic/bitwise + min/max/abs/ round/int/float; names/attrs/arbitrary calls rejected at load -> a community profile CANNOT execute code. - obdcore/profile.py: load/save/list profiles; compiles each formula into a decode callable. registry.py now profile-backed (PidRegistry/DtcDatabase take a Profile); hardcoded Ford table removed. - store.py: clear()/snapshot()/export_csv() for capture management. Profiles: - profiles/ford-6.0-powerstroke.json (27 PIDs, verified formulas, DTCs) - profiles/generic-obd2.json (standard SAE Mode-01 base, any vehicle) - profiles/README.md (schema + formula language + contributing) GUI: - Menu bar: File (new/record/export/replay capture, quit), Profile (switch/ load/import/reload/edit-JSON/export, live profile list), View (Graph/Table views, gauges P2, toggle PID dock, normalize, light/dark theme), Help (about/confidence legend/profile info). - PID browser + presets rebuild on profile switch; added Table view; raw-JSON profile editor dialog (validates schema+formulas before saving). Tests: profiles load+compile, formula sandbox rejects hostile input, decoders still match real truck bytes, crank/derived/dead-PID/replay -- all pass.
