Center views [UI]

# Center views `[UI]`

Navigation is two layers: the **SectionRail** picks one of 5 sections, the **StageBar** switches the `stageView` within it. `Stage.tsx` is a render switch on `state.stageView` (~33 modes); the persisted literals are the source of truth (`view-state.ts`).

    Rail --> Base & Content & Mind & Program & Watch

    subgraph Base["**BASE** — the world as geometry"]
        b1["Tree · World · Network · Board ·<br/>Articles · Influence (Sankey)"]
    end
    subgraph Content["**CONTENT** — the authored move (per scene)"]
        s1["Plan · Prose · Script ·<br/>Audio · Learning · Perspective"]
    end
    subgraph Mind["**MIND** — reasoning + belief"]
        c1["Reasoning Graph · Readings · Threads ·<br/>Mode (PRG) · Decision · Search"]
    end
    subgraph Program["**PROGRAM** (Station) — the human loop"]
        p1["Inbox · Operations · Reminders ·<br/>Opinion (Thread/Stream/Position) · Notes"]
    end
    subgraph Watch["**WATCH** (Signals) — evidence in motion"]
        w1["Streams · Merges · Cycles ·<br/>Positions · Runs"]
    end
```

- **Program (Station)** is the human loop — Inbox feed, Operations agenda, Reminders, the Opinion dashboard (belief source toggles Thread / Stream / Position), Notes. **Watch (Signals)** is evidence in motion — Streams, Merges, research Cycles, Position monitors, the Runs log.
- The **Tree** anchors Base alongside the graph domains; the System and Fate node-edge graphs were retired, so system knowledge + threads render as leaves of the shared topic Tree.
- Adding a view = a `StageView` literal (`types/domain/view-state.ts`) + a `StageBar` button + a `Stage` branch (copy an existing one).
