From c6e6c04f5ca42a69e27db74f0caa2e070896bdeb Mon Sep 17 00:00:00 2001 From: Vance Ingalls Date: Tue, 18 Aug 2026 22:28:47 -0700 Subject: [PATCH] fix(studio): close four gaps found against the rendered designs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Until now I had only the ASCII stand-ins in `plans/audio-mixer-groups.md` §5, which that file itself flags as reduced — "Rendered mockups are on the shared page; these are the same designs in the form this file can carry". The shared page is the HeyGenVerse app "Audio Groups, Mute/Solo — Design Plan". Read against it, four things were wrong or missing: **A muted group's name is not struck through.** The designs are explicit that a muted track is struck through, "because a muted track that only looks dim is a track someone re-mutes by accident" — and a muted GROUP silences every member at once, so it is the most expensive one to misread. Plain track rows already did this; the group header did not. **A group's automation lanes had no label column.** The curve rendered on the canvas with nothing naming it. The designs draw `▤ Volume 0.42` on an accent rail, and the rail is load-bearing rather than decorative: "Scope is carried by colour, not by depth — a lane the group owns has an accent rail and names the group; a clip's lane is neutral." Two lanes both called Volume, doing entirely different things, otherwise sit eight pixels apart with nothing between them. **The number has to be the value at the playhead.** Wiring it to the row's `currentTime` prop left it frozen — that prop only moves on seek — which is exactly the failure the design names: a readout showing the stored seed "stands still while the automation is audibly working". It reads the live playhead now. Verified across the curve: 0.99 at t=0, 0.85 at the trough, 1.00 at t=20. **The rack's IN/OUT copy was the ASCII's, not the design's.** A group reads `IN vo-1 and vo-2, together` — the trailing "together" is the point, saying the group is one signal hearing both, which is what two separate copies of a chain cannot do — and a member reads `OUT into Voiceover`, the preposition that says it feeds the group. I had built `vo-1, vo-2` and `to Voiceover` from the ASCII.
