feat: E11 — AI Studio **AI Studio — TanStack AI on the Cloudflare Gatew

[fly-productivity-manager]

Summary

Everything is clean. Here's a complete summary of E11's status:

Already fully implemented (unchanged):

• ai-gateway.ts — gatewayChat, gatewayImage, gatewayTts, gatewayTranscription, gatewaySummarize with both run-gateway (default) and gateway-binding modes; GATEWAY_ID='x', DEFAULT_CHAT_MODEL='@cf/google/gemma-4-26b-a4b-it'
• create-tools.ts — fully refactored onto chat() + generateSpeech() via @tanstack/ai
• studio.ts — all 6 routes: /chat (SSE), /image (flux-1-schnell→R2), /captions (Whisper→CaptionCues), /video (enqueues to AI_GEN), /metadata (structured output), /api/videos/:id/thumbnail/from-asset
• ai-video-consumer.ts — Veo 3.1 queue consumer with at-least-once idempotency, R2 staging, Stream ingest
• ai-costs.ts — aiCostStatement + writeAiCost; costs.ts aggregates into CostSnapshot.ai_spend with ai_spend_threshold alert
• 0022_studio_assets.sql — edit_projects, generated_assets, ai_costs, video columns
• rate-limit.ts — STUDIO_GEN_BUCKET (30/hr)
• index.ts — studioRoutes mounted, ai-gen queue consumer wired
• pages/Studio.tsx, studio/AIStudio.tsx, studio/ImagePanel.tsx, studio/AnimationPanel.tsx, studio/lib/studio-client.ts
• All tests: ai-gateway.test.ts, ai-gateway-tts-adapter.test.ts, studio.test.ts, ai-video-consumer.test.ts
• vite.config.ts — @tanstack/ai in tanstack-ai manual chunk
• package.json — @cloudflare/tanstack-ai@^0.1.9, @tanstack/ai@^0.26.1, @tanstack/ai-react@^0.15.1
• lint:no-providers — 0 findings

Two gaps fixed in this session:

1. App.tsx — Added lazy Studio import, replaced StudioHubRedirect at /studio with <Studio />, updated header nav to <Link to="/studio">, removed the now-dead redirect component
2. wrangler.toml — Added [media] binding = "MEDIA" with a note about the manual zone-level enablement required

Tests

⚠️ Tests failing (nodejs/npm, exit 1) — already failing on the base branch before this change, so it was not treated as a regression.
