+# Design decision 001 — Main window layout
+
+**Decision (2026-07-11): Layout B, library-centric.**
+
+Owner choice from docs/design/wireframes.html.
+
+## Shape
+- Main window = clip table (sortable, dense, 44px rows), project tree left
+  (days / cameras / jobs), inspector right (selection metadata + grade snapshot + actions).
+- Live grading = inspector mode when a camera slot is selected, plus a summonable
+  grade drawer (preview + node strip — Layout A distilled) for panel/trackball work.
+  Keyboard: ⌘G toggles drawer; slot switching stays single-keystroke.
+- Jobs (offload/verify/proxy) surface in the tree with inline progress — matches
+  Silverstack's workstation posture and our offload/proxy engines.
+
+## Consequences for macOS phase
+- NavigationSplitView: sidebar (tree) / content (table) / inspector — B maps 1:1
+  to native three-column. Grade drawer = bottom sheet over content column.
+- Table virtualization + SF Mono numerics from day one.
+- Panel focus model: active slot follows either table selection (camera row) or
+  explicit slot keys — must never steal focus during rec.
+
+## Skin (unchanged)
+Reel tokens: bg-0 chrome, amber accent as tally, #FF3B30 reserved for REC,
+SF Mono for TC/CDL/clip names, hairline dividers, 10.5px uppercase eyebrows.

-  <h3>Recommendation</h3>
-  <p><b>Layout A as the main window, with B's table one ⌘-key away (Library tab/window).</b>
-  Forge's differentiator is in-camera live grading — the app should open into the moment
-  it wins. The library table (B) is genuinely better for end-of-day work, so ship it as a
-  second surface using the same panes, not a compromise hybrid of both.</p>

+  <h3>DECISION (2026-07-11): Layout B — library-centric</h3>
+  <p><b>B is the main window.</b> The clip table is home; days/cameras/jobs tree left,
+  inspector right. Live grading enters through the inspector when a camera is selected,
+  plus a summonable full-width grade drawer (preview + node strip from Layout A) for
+  trackball sessions — A survives as a mode inside B, not a separate window.</p>
+  <p>Shared skin: bg-0 chrome, amber tally accent, #FF3B30 strictly for REC,
   SF Mono for TC/CDL/clip names, hairline dividers, 10.5px eyebrows — family resemblance
   to dragonflight without pretending to be a web app.</p>
