flemming-it fb809a4cbd feat(studio): show the model download instead of a spinning button 
Pulling a model moves gigabytes and could take fifteen minutes behind
a 14-pixel spinner. The model picker now follows the hub's pull stream
and shows a bar with the backend's own status and the megabytes for
the layer in flight.

The byte counts describe the current layer, not the whole model, so
the bar restarts per layer. That is deliberate and stated in the code:
the backend never says how many layers are still coming, so a single
overall number would have to be invented.

Ch∆In Studio

Desktop GUI client for the Ch∆In Platform hub. Tier-2 generic platform client per docs/architecture/client.md in the platform repo. Connects to a local or remote chain serve over gRPC / gRPC-Web.

Status: live product (v0.70+). Every page talks to the hub through chain_client_sdk; there is no mock data. End users launch Studio via chain studio, which downloads and verifies a prebuilt bundle from the release mirror (sha256 + signature) or rebuilds from source when a dev workspace is configured.

Pages

  1. Welcome — onboarding checklist, guided setup wizard, bundled documentation reader.
  2. Store — browse/search/install modules across multiple stores (pinned publisher keys, private sources, AI AskBar); installed modules live here as a filter.
  3. Flows — graph + text flow editor with a live Run tab (streamed step events, inline approvals). Editor ships as the chain_studio_flow_editor package.
  4. Audit — live event stream (StreamEvents) with filters, hash-chain verification, gated log reset.
  5. Approvals — pending system.approval@^0 reviews with approve / reject and payload disclosure.
  6. Doctor — diagnostics, daemon lifecycle, binary recovery.
  7. Föderation — satellite list, bootstrap-token enrolment, revocation.

Plus: settings dialog (System-AI, integrations/MCP/n8n, security, maintenance), Cmd+K palette, release-channel switcher.

Stack

  • Flutter 3.40+ (Desktop: macOS, Linux, Windows)
  • gRPC client via chain_client_sdk (sibling repo; pinned by relative path during development)
  • No external runtime dependencies; bundles its own Dart VM

Run locally

flutter run -d macos      # or -d linux / -d windows
flutter test

chain studio prefers a configured dev workspace and will flutter run from source when one resolves — see crates/chain_runtime_mgmt in the platform repo.

Repo placement

Published as fai/chain-studio on Forgejo (git.flemming.ai). The local directory follows the established fai_chain_* layout convention.

Why "Studio" and not "Stage"

"Stage" collided too easily with "staging environment" in developer English. "Studio" is the established industry pattern for creator-tools (Visual Studio, Android Studio, RStudio) and matches the GUI's audience of module developers, operators, and power users.
