refactor(brand): rename F∆I -> Ch∆In + hub binary fai -> chain
Studio follows the platform rename: product branding F∆I -> Ch∆In in UI
strings, command examples fai -> chain, and — critically — the spawned
hub binary path ~/.fai/bin/fai -> ~/.fai/bin/chain so Studio launches
the renamed binary. The fai_* Dart identifiers (FaiLog, widget files,
the generated SDK) stay = vendor/internal namespace. flutter analyze:
no issues.

# Ch∆In Studio
Desktop GUI client for the Ch∆In Platform hub. Tier-2 generic
platform client per `docs/architecture/client.md`. Connects to a
local or remote `chain serve` over gRPC.
> **Status (2026-05-05):** MVP scaffold. Three pages with mock
> data, no live gRPC connection yet. Validates the visual
> direction before the Dart SDK is wired in.
## Pages (MVP scope)
1. **Modules** — installed modules, capabilities, declared
permissions. Click → manifest detail.
2. **Audit** — live stream of hub events (when wired). Filter
by event type and flow.
3. **Approvals** — pending `system.approval@^0` reviews with
approve / reject buttons.
These three cover the platform's central properties:
**composition** (modules), **audit** (events),
**human-in-the-loop** (approvals).
## Stack
- Flutter 3.40+ (Desktop: macOS, Linux, Windows)
- gRPC client via [`fai_client_sdk`](../fai_client_sdk_dart) (sibling
repo; pinned by relative path during development)
- No external runtime dependencies; bundles its own Dart VM
## Run locally
```bash
flutter run -d macos
```
## Repo placement
Will be published as `fai/studio` on Forgejo (`git.flemming.ws`).
The local directory `fai_studio/` follows the established
`fai_platform/` 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. The rename was applied across all `docs/` in the
platform repo on 2026-05-05.
