docs(consultations): Gemini response on The Forge architecture

All 5 recommendations validated:
- PixiJS confirmed over Canvas 2D and Three.js
- SSE + Node EventEmitter (code provided)
- Midjourney --sref + locked seed for asset consistency
- FSM + GSAP for camera system (code provided)
- Phase 1 polling-only until after April 15 launch

Key boundary: No SSE event bus work before April 15.
Task #126 (Arbiter Lifecycle Handlers) remains priority.

Gemini asked about Phase 1 deployment target (Arbiter vs Cloudflare Pages).

+## Gemini's Response (April 11, 2026)
+
+**Summary:** Validated all five recommendations with specific technical rationale. Confirmed PixiJS, recommended SSE with Node EventEmitter (provided code), endorsed Midjourney --sref workflow for asset consistency, proposed FSM + GSAP for camera system (with code), and delivered a critical sanity-check boundary: no event bus work before April 15 — polling only for Phase 1.
+
+### Key Recommendations
+
+**1. Renderer — PixiJS confirmed**
+Raw Canvas 2D becomes unmanageable with hundreds of bezier particles + glowing blend modes + layered PNGs. Three.js is overkill for a 2D plane and wastes Pi 5 resources. PixiJS gives WebGL hardware acceleration with a 2D API and automatic Canvas 2D fallback.
+
+**2. Event Bus — SSE + in-memory EventEmitter**
+WebSockets are bidirectional overhead for a read-only display. Redis is architectural bloat for a single-node Node.js app. SSE is native browser API (EventSource), handles auto-reconnection, lightweight. Gemini provided a complete `forgeBus.js` module and Express streaming route.
+
+**3. Asset Pipeline — Midjourney with --sref + locked seed**
+Generate one hero asset first (Command Center spire), then use its URL as `--sref` for all subsequent prompts, combined with locked `--seed` and identical prompt templating changing only the subject. Nano Banana 2 available for rapid geometric iteration before committing to illustrated renders.
+
+**4. Camera/Animation — FSM + GSAP**
+Three states: AMBIENT_CYCLE, EVENT_INTERRUPT, RECOVERY. GSAP handles the tweening (lightweight, native easeInOutCubic, tweens PixiJS containers directly). Gemini provided FSM skeleton and interrupt handler code.
+
+**5. Sanity Check — Phase 1 is perfectly sized BUT**
+Critical boundary: **no SSE event bus work before April 15.** Use only the existing polling mechanism (`/admin/infrastructure/refresh` every 60s) for Phase 1. Static Canvas/PixiJS with colored dots + polling proves the visual concept without risking launch-critical Arbiter time. Task #126 remains undisputed priority.
+
+### Gemini's Return Question
+
+*"How are you planning to structure the deployment of the Phase 1 static files — will they be served directly through a new Arbiter route, or are you pushing them to Cloudflare Pages right away?"*
+
+---
+
+## Conclusion
+
+Every architectural decision validated. Gemini pushed back exactly where we needed it — on the timeline boundary. The polling-only Phase 1 constraint is wise: it means The Forge can start existing on a wall before April 15 with zero risk to launch work, because there's no new backend code required. Just a static HTML/JS page hitting an endpoint that already exists.
+
+**Next Steps:**
+1. Answer Gemini's deployment question (decision pending with Michael)
+2. Integrate refined decisions into task-127 task file
+3. Begin Phase 1 ONLY after April 15 launch — or as a genuine spare-time diversion if Michael wants (no pressure)
+4. Revisit for Phase 2 architecture consultation when ready to add real-time events + illustrated assets
