+## Launch prompt
+
+```
+Let's start talking about hardware. Let's assume for the first version I'm ok having my computer or laptop do the rendering. We'd still want a controller but it could be connected to the computer via wifi, USB, or bluetooth and would send commands to the software we've already written that would adjust left brain, right brain, etc. We'd prototype this by having a controller simulator run on another device, such as an ipad (just riffing here) but eventually move to a physical remote running on an Arduino or similar
+```
+
+## Pre-state
+
+- Simulator is a **FastAPI** app, **stateless**: the single browser holds knob
+  state in JS and POSTs to `/api/alteration` for a `RenderPlan`. Renderer and
+  controller are the same browser tab.
+- Operator-facing control surface (sim today): Content (7-way `<select>`),
+  Altitude (endless circular dial across 5 scales), Left/Right (sliders 0–4),
+  Mood (slider −4…+4). (Dark+Light → Mood in s0013; Altitude dial in s0018.)
+- ROADMAP sub-project 4 = "Arduino Firmware (control panel)" assuming a **Pi**
+  runs the room and the panel talks **USB serial** to it.
+- Standing directive: simulator-first before hardware.
+- Checkout shared with a concurrent audio-sourcing session (0017/0018), with
+  uncommitted `.gitignore` + untracked files on `main`.
+
+## Arc
+
+1. **Session gate / routing.** Classified the opening ("let's talk about
+   hardware… just riffing") as **brainstorming**; invoked `wgl-brainstorming`,
+   claimed session **0019** (`--type brainstorming`, careful posture). Three stale
+   `--INPROGRESS` sessions (0015/0017/0018) noted as leftovers, not live overlaps;
+   no worktree (the audio session's edits are unrelated/uncommitted).
+
+2. **Orientation.** Read `docs/ROADMAP.md` + the simulator (`app.py`, `index.html`)
+   to ground the discussion; confirmed the real control surface and the stateless
+   architecture. Recognized the request as a **reframe** of sub-project 4.
+
+3. **Brainstorming dialogue** (`superpowers:brainstorming`), decisions reached:
+   - **Intent:** both — decouple control/display cleanly AND want the handheld feel.
+   - **Transport (v1):** wifi/web (iPad opens a controller page off the FastAPI
+     server; least friction; Arduino transport left open).
+   - **Remote fidelity:** faithful twin — decide the physical panel inventory now,
+     iPad mirrors it.
+   - Operator refinement: **per-knob transition state** — live controls
+     (Left/Right/Mood) are instant; transitional ones (Altitude, Content) carry a
+     lifecycle so the remote's feedback is honest.
+   - **Architecture:** approach A — server-authoritative `SessionState` + **SSE**
+     push (chosen over polling / WebRTC).
+
+4. **Design presented section by section** (roles → transition model → server
+   contract → two pages + Arduino seam → error/test/scope), each approved.
+
+5. **Spec written** to
+   `docs/superpowers/specs/2026-06-26-networked-control-surface-design.md`,
+   committed on `feat/networked-control-surface`, pushed; operator approved going
+   straight to finalize.
+
+6. **Finalize.** Single-repo app (CONTENT_REMOTE empty) → merging the branch IS
+   the submission. Discovered the shared checkout had switched to `main` (the
+   audio session) and `main` had advanced to PR #25; landed the spec via a safe
+   local `--no-ff` merge that added only the new spec file (their uncommitted work
+   untouched), pushed `main` (`229af60..f28a06c`), deleted the feature branch.
+
+## Cut state
+
+- `main` @ `f28a06c` — spec merged. Feature branch deleted.
+- Spec `status: proposed` (careful posture); operator reviewed it live, approving
+  every section before write.
+- No code written (brainstorming session). 0 new tests (none applicable).
+- Concurrent audio session's uncommitted `.gitignore`/untracked files left intact.
+
+## Deferred decisions
+
+_None — no autonomous low-confidence calls. The two flagged design choices
+(last-write-wins concurrency; no auth in v1) were presented to the operator and
+approved in-session, not deferred._
+
+## Operator plate
+
+- Review the merged spec if desired:
+  `docs/superpowers/specs/2026-06-26-networked-control-surface-design.md` on `main`.
+- Next: open a **writing-plans** session to turn the spec into an implementation
+  plan (the `/goal` below).
+
+## Next /goal
+
+```
+/goal Write the implementation plan for the networked control surface, per docs/superpowers/specs/2026-06-26-networked-control-surface-design.md
+```
