Summary​

ASCII wireframes for eight CM5 operator screens. Each frame cross-links PLC tags from hmi-bindings (controls/water/hmi/bindings.md) and controls/water/tags/tags.csv.

ScreenPurposeKey tags

Navigation spine: Splash → PIN (future) → HomeMain → sub-screens per controls/water/hmi/screens.md.

Test​

CM5 offline simulator — walk each screen against tag browser; confirm widget IDs in hmi-bindings resolve.

Scenario cross-checks:

  • sim-alarms-ack-wave.md — AlarmActive ack path
  • sim-recipe-change-mid-fill.md / sim-delta-recipe-propagation.md — RecipeSelect / RecipeEditDelta
  • sim-cooling-stages.md / sim-tt200-overtemp.md — CoolingDetail
  • sim-uv-fault-mid-fill.md — UVDisinfectWizard

Changelog​

  • 2026-05-24 — Authored full ASCII wireframes for HomeMain, RecipeSelect, RecipeEditDelta, AlarmActive, TrendsMulti, CoolingDetail, UVDisinfectWizard, DiagnosticsForces. Renamed nav nodes RecipeDeltaPop → RecipeEditDelta, AlarmsAck → AlarmActive, UVWizard → UVDisinfectWizard. Cross-linked all bound widgets to bindings.md and tags.csv.
