flemming-it 14f9217007 feat(studio): show what a running update is doing, not just that it runs 
Applying an update downloads and swaps a binary and takes minutes; the
doctor showed a spinner inside a disabled button for the whole time.
SystemActions gained a streaming CLI runner that hands each line to the
caller as it arrives, with CHAIN_PLAIN=1 set for the child so the CLI
emits one line per transition instead of its redraw-in-place block.

The update card now shows an indeterminate bar labelled with the
running step and an elapsed counter on its own timer, so the counter
keeps moving between lines that can be minutes apart. No invented
percentage: the CLI reports steps, not a measurable total.

The streaming path still defers to debugRunFaiOverride, so tests stay
hermetic and never spawn a process; three guards pin that.

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.
