The Studio design system, widgets and helpers carried a Fai* / fai_
prefix (FaiSpace, FaiColors, FaiTheme, FaiLog, 17 fai_*.dart files, the
faiBinary* l10n keys). Studio is the Ch∆In product, so rename them to
Chain* / chain_ — carefully preserving English fail/failure/failed.
Also fix stale references: the 'fai' binary in l10n strings -> 'chain',
FAI_* env vars (FAI_BIN/DATA_DIR/MODULES_DIR/TODAY/BOOTSTRAP_TOKEN) ->
CHAIN_*, fai_platform -> fai_chain, fai_hub -> chain_hub. Vendor
security-hook tooling (FAI_BANNED_TERMS_FILE) + the .fai bundle ext left.
flutter analyze + test: clean (20 passed).

Studio is the Ch∆In product's GUI, not a F∆I-vendor app. Rename the
Flutter package, all package: imports, and the build identity across
platforms: linux/windows CMake BINARY_NAME + project, Windows Runner.rc
fields, macOS PRODUCT_NAME / bundle id (ai.flemming.chain.chainStudio) /
.app + scheme BuildableName. Update the client-SDK + flow-editor deps to
their renamed chain_* packages (path + git URL). Company/copyright fields
now read Flemming.AI. flutter analyze: clean.

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.

Two follow-ups to the May-2026 trust pass.
flutter_markdown_plus migration:
- pubspec swaps `flutter_markdown ^0.7.7` (discontinued
upstream) for `flutter_markdown_plus ^1.0.3`, the
actively-maintained fork. API surface
(MarkdownStyleSheet, Markdown, MarkdownBody) is
unchanged — the four import sites in welcome, store,
flow_output, and theme.dart get an updated package
string and that's it.
- All Studio analyzer + unit-test suites stay green.
Integration test scaffold:
- New `test/integration/hub_fixture.dart` boots a real
`fai serve` subprocess on a free port against a temp
FAI_DATA_DIR, polls until Healthy, exposes a ready
HubClient. Idempotent teardown wipes the temp dir.
- Resolves the `fai` binary from PATH first, then from
`../fai_platform/target/release/fai`. When neither
exists, the fixture calls `markTestSkipped` with a
clear message — fresh checkouts don't fail.
- One canonical test in `capabilities_test.dart` asserts
on the bug class the May trust pass surfaced: that
`system.approval` appears in `list_capabilities` with
`kind=builtin` so Studio's missing-deps check never
tries to install it. Plus a contract-shape test that
every cap's `kind` is one of the three known wire
values.
- README documents the cold-start gotcha (first
`fai serve` per machine takes ~30s to build the
curated-model DB) plus the manual warmup recipe.
Not in CI yet — wiring needs the platform build job to
publish `fai` as a CI artifact for downstream consumption.
Deferred until enough integration tests exist to justify
the CI minutes.
