test(skew): version-skew smoke — dev Studio against the released hub 
Walks every sidebar page against an older, released chain binary
(hermetic fixture hub) and fails when any page claims 'unreachable'
although the hub answers, or renders raw error text. Run via the
platform repo's scripts/skew-smoke.sh as a Studio release gate.

Verified against the real pair hub 0.21.0 vs workspace 0.22.0: all
invariants hold. Two timing notes are handled explicitly: real-async
settles between navigations and an app teardown before the fixture
teardown keep grpc-dart's data-after-cancel race (unguarded
_responses.add, call.dart:395) from failing the walk spuriously;
the final fake-time pump drains the channel's 5-minute idle timer.

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.
