Phase 1 group 5 (S15, S16, S18, S19, L22, L23, L20, L21, L1 delete-half).
- S15: the four-way focus/altitude system. setFocus was never called anywhere,
so only the 'composite' branch was reachable. Deleted SplitStage,
ReadoutStrip, InputMini, AltitudeNav, CompactAxis, the UI Focus type/prop,
the focus branches, stripPinned and the vacuous keyboard gates. MiniMeters
kept; engine.feedback.setFocus (a different, live thing) untouched.
- S16 + L1: the decorative stratum that rendered real-looking controls driving
nothing — A/B machinery, the fake seed, seededGradient + weightsRevision,
snapshots, master volume, bpm, and the learningRate/decay/tame/spreadLevel
sliders with their Drawers rows. Each was confirmed self-referential first.
NOTE a real behaviour change falls out of dropping `snapshots`: Undo outside
an active explore-and-place session used to pop a UI-only snapshot that
restored noiseCap/seed. It is now simply inactive unless a genuine
core-backed scratchpad undo exists. Geometric-dislike mode never had a real
undo primitive in the core, so only the fake path is gone.
- S18: BackendAdvanced.tsx and its Drawers block. It self-described as a
duplicate of the inline OutputsBackendConfig editor and BOTH rendered in the
same expanded drawer. OutputsBackendConfig already covers every backend.
- S19: pruned ConsoleCtx to the fields Dock/Drawers/OutputsBackendConfig
actually read; deleted the Axes type + axes/setAxis and the
preset/setPreset/offsetActive chain (permanently 'Sculpt'/false).
KEPT ctx.modes and ctx.setModeId despite having no reader today — the
Phase 5 instrument picker (§7.6, adopted) is built on exactly that plumbing.
- L22: the 5 dead primitives (Panel, StatusLine, ControlAxis, CurvePlot,
Sparkline) and their barrel exports, plus the now-dead .mf-axis-input CSS.
- L23: OutputControl/toOutputControl, ModeIconComponent and the BACKENDS
catalogue; Drawers now reads modeDesc.label/description from OUTPUT_MODES,
the surviving single catalogue.
- L20: the solo-mode selector's two unimplemented options no longer pretend to
be selectable.
- L21: FeedbackController vestiges — seed/undoDepth options, maxUndo, and six
ControllerEngine members nothing called (the finding named three; the other
three are used on the real EngineApi by debug/probe.ts, a different
interface, so removing them from ControllerEngine is safe).
Gates: run-all-tests.sh ALL GREEN (typecheck, 33 Playwright specs).
