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`.

Sweeping pass against six user reports collected this session.
1. "Capabilities ist nicht deutsch, Chain auch nicht."
The DE locale still leaked English vocabulary. Replaced
"Capabilities" → "Fähigkeiten" and "Chain" / "Hash-Chain"
→ "Kette" / "Hash-Kette" everywhere — store search hint,
recommended-source body, federated toast, doctor summary
chain row, modules panel summary, MCP / n8n hints, the
approvals history blurb. Wire-level identifiers
(`chain.reset`) stay as code.
2. "Bei Fehlern unten muss man die auch ins clipboard
kopieren können." New `FaiErrorBox` widget: selectable
monospace block with a small copy-to-clipboard icon
button that flips to a checkmark for two seconds after
click. Applied to the Doctor update banner output and
the Settings channel toast — the two places long
stderr / stdout lands.
3. "Öffnen bei Log kann es nicht öffnen. Audit-DB auch
nicht. PID auch nicht."
Cause: `SystemActions.openInOs` shells out to `open` /
`xdg-open` on file paths the OS has no default handler
for (SQLite DB, PID file, log without an .ext that
binds). New `revealInOs` uses `open -R` on macOS,
`explorer /select,` on Windows, and the parent
directory via `xdg-open` on Linux. Doctor's path rows
carry an `isDirectory` flag that routes through the new
`openOrReveal` so files reveal in Finder / Explorer
instead of failing silently.
4. "Oben im Store könnte man diesen Redaktionshinweis auch
so bauen, dass man mit pfeil nach rechts links auch
weitere anzeigen kann."
The Today-Hero became a carousel. Curated fallback
list grew from one entry to four (public sources, the
sandbox-by-default permission story, the hash-chained
audit story, the air-gap-ready single-binary pitch).
Hero gets prev / next chevrons plus a dot indicator
when the current snapshot has more than one slide.
Operator-accepted stories stay single — the carousel
collapses when there's only one to show.
5. "Ich fände es schöner wenn rechts und links im Store
die Abstände konsistent sind, das Reload-Symbol rechts
ist zu weit rechts und Store links auch nicht bündig."
AppBar now has `titleSpacing: FaiSpace.xl` so the
title's left edge sits flush with the body's left
padding (24 dp), and the trailing `SizedBox` after the
reload icon shrunk so the icon's outer edge meets the
right edge of the rightmost grid card.
6. "Oben der Titel zeigt fai_studio an, das sollte F∆I
Studio sein." The OS window title was the
pubspec-derived "fai_studio". Macos/Linux/Windows
runners now hard-code "F∆I Studio" (with the U+2206
triangle escape so the C++ source stays ASCII). macOS
bundle name and display name lifted out of the
PRODUCT_NAME variable for the same reason.
