The widget suites used to talk to whatever listens on the real
endpoint — results depended on the operator's machine (a running
hub fed real data into a11y/responsive runs and its gRPC channel
timers caused the historic flake). Hardening round:
- HubService.instance is now injectable (debugSetInstance);
FakeHubService (test/support/fake_hub.dart) answers every member
the pages touch with healthy-empty defaults and scripts per-RPC
failures (UNIMPLEMENTED / UNAVAILABLE / detached gate) through a
GrpcError-shaped fake. Unimplemented members are recorded and
fail the sweep with the exact list.
- state_matrix_test.dart pins the app-wide invariants for every
sidebar page x hub condition: healthy => no unreachable claims
and no raw error text; hub gone => honest unreachable states;
UNIMPLEMENTED => never 'not reachable' while the sidebar shows
connected; detached gate => plain-language feature-off state.
- a11y + responsive sweeps now inject the fake (hermetic); the
6-minute idle-timer drain workaround is gone with the cause.
Real bugs the new sweep caught immediately:
- every data page (store, doctor, audit, approvals, federation)
folded ANY load failure into 'hub not reachable' — the runs-page
bug class; they now share HubLoadErrorView, which classifies
into unreachable / needs-newer-hub / load-failed-with-copyable-
detail (new generic DE+EN strings)
- the approvals page's hidden tab had no future listener: a load
failure there surfaced as an uncaught async error
- the audit status bar rendered the raw gRPC error wall verbatim;
it now shows the classified friendly headline (still selectable)

The runs monitor folded every load failure into 'hub not reachable',
contradicting the sidebar's green connected dot whenever the hub
answered but the RPC failed — most visibly against a pre-0.22 hub
whose version predates the ListInvocations RPC (UNIMPLEMENTED).
Classify the failure instead (top-level, unit-tested):
- UNIMPLEMENTED -> 'this view needs a newer hub version' with a
doctor-page link (the update banner lives there)
- FAILED_PRECONDITION from the detached gate -> the regular
feature-off empty state with the guide button
- UNAVAILABLE / DEADLINE_EXCEEDED / socket-level failures -> the
honest 'hub not reachable' state (unchanged)
- everything else -> a load-failed state with the friendly error
and a copyable detail box
The error view is a public callback-driven widget so the tests pump
each variant without a live hub. New DE+EN strings for the too-old
and load-failed states; grpcCodeOf/grpcMessageOf exposed from the
friendly-error mapper instead of duplicating the duck-typing.

Field test of the setup wizard surfaced three trust breaks in one run:
an unexplained macOS Documents permission prompt, a perceived crash,
and an error message whose copy button could not be reached.
Root causes and fixes:
- chain init failures were shown as a SnackBar, which lands BEHIND the
wizard's modal barrier: dimmed, clipped, copy unreachable — and the
click aimed at it hit the barrier, dismissing the whole wizard with
all answers (the perceived crash). Errors now open a modal dialog
ABOVE the wizard via showChainErrorDialog with a copyable detail
block, and the wizard is no longer barrier-dismissible.
- When the resolved chain binary is older than Studio and rejects
--plan-json, the wizard now explains the version skew in plain
language (binary path + update path) instead of leaking a raw clap
usage error. A missing binary gets its own localized story.
- Step 3 announces which chain binary the preview will execute; when
that binary physically lives (symlinks resolved) in a TCC-protected
folder, the wizard pre-explains the macOS folder prompt.
Supporting changes: FriendlyError passes through friendlyError()
unchanged so call sites can ship precise localized stories through the
shared presentation; SystemActions gains resolvedChainBinary() plus
run/resolve test seams; ChainErrorBox hugs its content instead of
filling an unbounded dialog; the wizard's answers file is written
synchronously (the async dart:io variants never complete under the
widget-test fake-async zone).
Verified: flutter analyze clean, 53 tests green (6 new wizard error-
path tests incl. clipboard round-trip), plus a live GUI walk on macOS
in dark + light with a stale binary (skew dialog, copy verified via
clipboard) and with the real binary (TCC pre-explanation with the
resolved path, full plan preview).

friendlyError now pattern-matches module-download failures ('download
failed: ...') and renders a clear, copyable headline + the URL/status
detail, instead of letting the gRPC-Unavailable default show the generic
'hub not reachable' banner. EN+DE l10n.

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.

Generic gRPC-code mapping was right but not specific enough.
A flow failing with an approval-timeout used to land on
'Deadline exceeded — try again later'; now it reads 'Freigabe-
Timeout abgelaufen — entweder timeout_seconds erhöhen oder
den Reviewer informieren.'
New pattern matchers in _matchHubPattern, runs before the
gRPC-code switch. Six FlowExecutionError shapes covered:
- approval rejected ("rejected by")
- approval timeout
- output too large ("exceeding the X MB cap")
- host service not declared
- missing value reference
- MCP endpoint unreachable
- capability not installed (NotFound fallback)
Every match comes with a localised hint pointing at the
concrete fix path (audit log / timeout config / Integrations
panel / Text-tab Fix button).
Five new tests pin the matchers — would catch a silent
regression when the hub renames a variant Display string.
All 11 friendly_error tests + 19 Studio tests green.

The Dart SDK package was renamed package: fai_dart_sdk →
fai_client_sdk and the dir + Forgejo repo got a -dart language
suffix per the three SDK families convention in
fai/platform/docs/architecture/sdks.md. Updates the path
dep, dep name, every `package:fai_dart_sdk/...` import, and
the one comment that named the SDK.

Second half of the May-2026 trust pass. Drops the wall of
gRPC trailers from every error surface and makes the Store
honest about what is and isn't installable.
Friendly errors:
- New `friendlyError(Object, AppLocalizations)` mapper turns
GrpcError + arbitrary throwables into a localised headline,
optional recovery hint, and a verbatim detail string kept
behind a "Show details" expander. Duck-typed on `.code` /
`.message` so Studio doesn't have to depend on package:grpc
directly.
- `FaiErrorBox` gains an `error:` constructor that runs the
mapper. Every call site that used to render
`snap.error.toString()` (flows, welcome, store) switches to
it.
- 9 .arb entries per locale cover the gRPC codes we actually
emit (INVALID_ARGUMENT, NOT_FOUND, ALREADY_EXISTS,
PERMISSION_DENIED, FAILED_PRECONDITION, INTERNAL,
UNAVAILABLE, UNAUTHENTICATED) plus copy/details affordances.
- `test/friendly_error_test.dart` — 6 unit tests for the
mapper. Covers the mapping table, locale-switching, and the
non-gRPC fallback so future regressions show up in CI.
Capability discovery:
- New `HubService.allCapabilities()` reads the kind-aware
capability list (wasm + builtin + federated) and returns a
Dart-side `CapabilityInfo` value type. The flow page's
missing-dependency check uses it so `system.approval` and
federated MCP/n8n tools count as "available" — fixes the
Run button staying disabled forever.
- `HubService.listModules()` filters to kind=wasm so the
Modules page doesn't sprout synthetic "system" entries that
the operator can't uninstall.
Store clarity:
- New "Installable only" filter, on by default. Roughly 2/3
of seed entries currently carry `status: planned`; the
default view stops being noise.
- Featured-strip cards for planned modules now show a
"Coming soon" pill instead of an empty action area.
- Main-grid cards for non-installable modules dim to 60%
opacity so the eye lands on actionable cards first.
- Detail-sheet "Nicht installierbar" tooltip → inline hint
box. The reason is visible without hovering.
MCP localisation:
- `_kMcpSuggestions` no longer holds 11 hardcoded English
description strings. The `description` field is replaced
with a `resolveDescription(AppLocalizations)` lookup that
switches on the suggestion `name` to read the matching
`mcpSuggestion*Desc` .arb key. EN + DE shipped.
- New `FaiEnBadge` widget renders a small `[EN]` pill when
the active locale isn't English. Used next to MCP /
federated store entries' tagline + description because
the server supplies them in English and we can't translate
on the fly yet — the badge is the honest signal until the
planned `studio.translate` plugin lands.
Plus housekeeping: removed the unused `_keepImport` lint
escape in the test and the dangling library doc-comment in
`format.dart`.
