  1. M3/M4: interactive chart, checkpoints/generate/eval panel, crash recovery, watchdog
    …
    - TrainingChartView: hover crosshair with step/train/EMA/ppl/val callout,
  pinch-zoom + horizontal pan (chartScrollableAxes), follow-live pill that
  disengages on manual pan and re-pins to the latest data, double-click /
  fit reset, log-Y, best-val rule — replaces the static chart
- CheckpointsPanel on finished runs: checkpoint list (step/size), Generate
  (prompt/temp/top-k, streamed output) and Eval (loss/ppl) via forge CLI
- Crash recovery: runs persisted as active at launch are truthfully marked
  stopped, with the live-PID case called out; no lying states
- Watchdog: 'possibly stalled' badge when a running run's log.csv stops
  growing for 30s
- New Run: import/export Forge-compatible JSON configs

  2. Forge Studio M1: SwiftPM app skeleton, full config codec, run supervisor, live dashboard
    …
    - RESEARCH.md: ground-truth Forge contract (config schema incl. waves 1-3,
  CLI, log.csv grammar with elapsed_s, checkpoint/resume, signals)
- ForgeConfig: byte-compatible Codable mirror of every model/train field,
  param-count formula cross-checked against forge info, LR-schedule math
- Services: ProcessRunner (actor, line streaming), LogParser (header-driven
  CSV + stdout events), MetricsStore (actor, incremental CSV tail, LTTB
  snapshots), RunStore (atomic registry), RunSupervisor (state machine,
  launch/stop, 1 Hz ingest), ForgeBinaryLocator, SystemInfo
- Charts: LTTB downsampler, bias-corrected EMA
- UI: NavigationSplitView shell, run rows/badges, RunDetail dashboard
  (loss raw+EMA+val, log-Y, best-val marker, LR/tok-s/grad-norm secondary
  charts, console), New Run sheet (presets, derived panel, LR preview,
  inline validation), Settings with forge-info validation
- scripts: package-app.sh (SPM -> .app, ad-hoc) and notarize.sh with the
  real zyquo-term identity (Team 3YM54G49SN, profile MacLustr-Notarize)
- 8 tests green: config round-trip vs real configs, param count, LTTB,
  EMA, CSV/stdout parsers, state machine, LR preview
