The icon-only rail forced first-time users to guess (usertest:
Senior, a11y, UX personas). Three changes:
- Nav tooltips appear instantly and carry the page shortcut
(Cmd+1..9, Ctrl on non-mac — Ctrl activators added); expanded
labels show the same hint. Explicit button semantics for
screen readers on every destination.
- A visible 'Search & commands' row above the footer opens the
existing Cmd+K palette, which nothing in the UI advertised.
- Settings -> Appearance gains 'Keep the navigation expanded':
pins the rail with permanent labels (persisted preference).
Footer strip and pillar toggle made overflow-safe for the
animating rail; responsive test scrolls the by-design scrollable
destinations list.

Stefan's live findings, all four addressed at the root:
- 'In 3 Fragen loslegen' read like ad copy → the entry is now plainly
'Einrichtung starten' / 'Start setup'.
- The setup button sat permanently on the Welcome page of a running
app ('setup after the app runs is backwards' — reported twice). A
fresh install now starts INSIDE the setup: SetupGateScreen hosts
the wizard embedded as the page (new embedded/onFinished modes on
GuidedSetupDialog), with an explicit 'Später einrichten' skip.
Welcome loses the setup button entirely and stays a calm intro.
- Re-running the setup later lives in Settings → General ('Run setup
again…'), the single post-first-run home.
- 'You must grant access first and only then see what will be done':
the preview used to spawn the chain CLI, whose first run could pop
the macOS permission prompt BEFORE the plan was ever shown. The
preview now calls the new PlanSetup RPC over the live hub
connection (no subprocess, nothing granted); the CLI remains only
a fallback when no hub is reachable — and applying stays the
explicit, separate step.
Widget tests: gate hosts the wizard + skip/cancel leave it; CLI-path
tests drive the fallback through the new hub-preview test seam.
Suite 76 green, analyze clean.

A black window on launch, no error anywhere: main() awaited
loadPersistedEndpoint before the first frame, and
SharedPreferences.getBool threw 'int is not a subtype of bool?' —
the store is writable from outside the app and hub.secure had been
written as int 0. Pref reads now go through defensive typed helpers
(int coerces to bool, wrong types fall back to defaults), and every
pre-frame restore step is failure-isolated: a broken store can cost
a preference, never the first frame. Regression tests stage the
corrupt store (the exact observed value and worse).
Also removes the CocoaPods leftovers from the macOS project
(Podfile, [CP] script phases, Pods framework references, xcconfig
includes): the project builds via Swift Package Manager, and the
dual wiring ran both dependency managers on every build — Flutter's
persistent 'removing CocoaPods will improve build time' warning.
Verified: clean profile build produces a launchable bundle (plugins
statically linked via SwiftPM), suite green, analyze clean.

Review follow-ups on the auth-status work:
- Both daemon-start paths classified an auth-rejected hub as "daemon
dead" via healthy() and showed a start-failure dialog while the
shell banner above correctly blamed the token. They now share
daemonAnswers(): only an unreachable probe counts as down.
- An auth-rejected poll now re-reads ~/.chain/hub-auth-token and
reconnects when the file changed, so a token fixed outside Studio
(CLI, editor) heals the connection without a restart — previously
the client kept the stale in-memory token forever and the banner's
own advice could not work.
- An endpoint switch resets the failure streak, so a stale in-flight
probe can no longer let the unreachable banner blame the new
endpoint for the old one's misses.
- The auth-policy panel re-queries when the hub token is saved or
cleared in the panel above (reloadTick), instead of keeping a
stale admin-denied hint; it also renders the hub's new
reload_required flag as a pending-reload warning (DE+EN).
- today-pipeline.md still documented ~/.fai/today after the rename;
the FAB theme comment now states the both-themes intent.

The sustained-failure banner treated every failed health poll as
'can't reach the hub'. With token auth active, a wrong or rotated
token gets UNAUTHENTICATED from a perfectly reachable hub — the
old wording sent the operator to fix the endpoint. The shell now
uses the SDK's probe() and, on auth rejection, switches the banner
to 'rejected the sign-in — check the access token' (key-off icon,
DE+EN). Two widget tests pin the wording per failure kind and the
banner clearing once the probe turns serving.

Settings → Security now shows the hub's effective auth policy via the

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).

The workspace switcher now lists the operator's sealed areas (read from
~/.chain/sealed/ manifests, the same source the CLI uses) below the
shared projects, each with a lock icon and a running/stopped status.
Selecting one is a real connection switch: Studio reconnects its hub
client to the area's own port with a full state reload — one window,
one truth. A stopped area is started first (chain project start) with a
visible notice; a failure surfaces as a copyable error and rolls back to
the shared hub.
While in a sealed area an identity bar under the AppBar is painted in
the area's accent colour and names it, with a one-click Leave back to
the shared hub. The area colour is marking, not theming — Studio's blue
stays the app accent. Selecting a shared project from inside an area
switches the connection back first. The sealed connection is never
persisted across restarts.

reads ~/.chain/current-channel (+ run/<ch>.endpoint) and follows the

From a live-test audit:
- Install via the flow-editor 'Fix' sent 'debug.echo@^0' (version
constraint included) as the install source; the hub resolves by bare
name so it missed ('no store entry for debug.echo@^0'). Strip the
@<constraint> like the Store page does — debug.echo now installs.
- Errors the operator could not copy: route the daemon-start failure
(its stderr!), the flow-editor install failure and the federation
issue failure through showFaiErrorSnack / a new showFaiProcessError
helper, so every error is selectable, one-tap copyable and logged.
- Diagnose page opened slowly because doctor() Future.wait-ed on a live

StudioFlowRunDriver gains three new methods that satisfy the
editor 0.21.0 FlowRunDriver interface:
- pendingApprovalIdForStep(flowName, stepId) — picks the
newest pending approval row matching this (flow, step)
pair from HubService.pendingApprovals().
- approveApproval(approvalId, reviewer) — delegates to
HubService.approve, same RPC the Approvals page uses.
- rejectApproval(approvalId, reviewer, reason) — delegates
to HubService.reject.
End result: when a flow run pauses on system.approval@^0,
the Run tab now renders a complete Approve / Reject form
directly under the awaiting step. Operator no longer needs
to switch tabs to make the decision; the standalone Approvals

- approval rejected ("rejected by")
- approval timeout

- host service not declared

- MCP endpoint unreachable
- capability not installed (NotFound fallback)
Every match comes with a localised hint pointing at the

Studio's Flows destination is now the swappable
fai_studio_flow_editor's full surface: a drag-and-drop
graph view, the raw YAML text editor, and the run tab
with inputs form + live step progress + outputs.
What's gone:
- The old saved-flows list + per-row run dialog.
- The separate "flow-editor" navigation destination (one
icon, not two — operators reach the editor by clicking
Flows, period).
- _FlowEditorAdapter (no longer needed; FlowsPage hands
the runDriver to the editor directly).
What's new:
- lib/data/flow_run_driver.dart — StudioFlowRunDriver:
adapter implementing the editor's FlowRunDriver. Maps
runFlow() to HubService.runSavedFlow and events() to
HubService.streamEvents filtered to step.* event types.
Converts proto-shaped FlowOutput variants to the editor's
host-agnostic FlowOutputValue family.

that loads capabilities into the editor's picker dropdown
and forwards the active locale.
Editor pinned to fai_studio_flow_editor 0.2.0 (commit

The flow-run dialog showed a single spinner + "running…" label
for the whole run. For multi-step flows the operator had no
way to see *which* step was busy or how close the run was to
finishing.
Replace the spinner with a live step list driven by a
StreamEvents subscription:
✔ extract 0.41s
⏳ summarize
◻ notify
━━━━━━━━━━──── 35%
Mirrors the `fai run` CLI rendering — one shared visual
language across both surfaces. Steps appear in execution
order as the hub emits step.started events; check + duration
on completion; cross + first-line error on failure; pause
icon on approval gates.
Implementation:
- HubService.streamEvents(backfill, types) — new public
stream-facade method that wraps HubClient.streamEvents and
maps proto LoggedEvent → AuditEvent for the rest of Studio.
Subscribed with backfill=0 so the dialog only sees events
from this very run.
- _FlowRunDialogState.initState subscribes BEFORE submitting
the run, so the first step.started never gets lost in the
gRPC handshake gap.
- Two-layer filter on incoming events: same flow name AND
timestamp >= dialog open time. The timestamp gate is what
stops a previous run's tail-end from painting stale rows
if the user re-runs the same saved flow.
- _LiveStep + _LiveStepList — insertion-ordered map renders
rows in runtime execution order (not alphabetical), so
what the operator sees matches what the hub did.

Two operator surfaces shipped together:
**Multi-version uninstall picker** — when more than one version
of a `(provider, name)` is installed side-by-side, both the
module-sheet "Uninstall" affordance and the store-detail
"Uninstall" affordance now ask the operator which version to
remove before calling the RPC. The hub's wire-level support for
this (UninstallModuleRequest.version) was already there; Studio
just wasn't using it. Picker pre-selects the highest version so
single-version flows still take one click.
- `HubService.installedVersions(name)` enumerates the installed
versions via the capabilities list.
- `HubService.uninstallModule(name, version: ...)` forwards
the version into the RPC.
- `_UninstallVersionPickerDialog` (module sheet) and
`_StoreUninstallVersionPickerDialog` (store) host the
picker — separate widgets so each surface can evolve copy
independently. Uses `RadioGroup<String>` for Flutter
3.32+ deprecation compliance.
**Default scope editor** — new DEFAULT SCOPE panel in Settings
that calls the freshly-added HubAdmin RPCs
`GetDefaultScope` / `SetDefaultScope`. Operators can:
- reorder publisher segments with up/down buttons
(first match wins in the bare-form resolver),
- delete entries (hub still rejects empty list — Studio
surfaces the constraint inline),
- add arbitrary entries via the text field,
- add catalog-known publishers via suggestion chips
(sorted alphabetically, populated from the catalog).
Every change persists to `~/.fai/config.yaml` via the hub
and hot-swaps the in-memory copy without a daemon restart.

found!); flutter test green (11 tests).

Studio gains a new "HUB AUTHENTICATION" panel in Settings
mirroring the existing registry-credentials panel:
- `lib/data/hub_auth_token.dart` — `~/.fai/hub-auth-token`
helper (read / write / clear, mode 0600 on Unix). Sister
of `RegistryToken` with the same on-disk hygiene.
- `HubService.loadPersistedEndpoint` now reads the token at
startup and reconnects with it. `reconnect()` grew an
`authToken:` parameter with a sentinel that distinguishes
"keep current" from "drop". `reloadAuthToken()` is the
one-liner Settings calls after save / clear.
- `_HubAuthTokenPanel` in `fai_settings_dialog.dart` — paste
with show/hide toggle, save button, clear button, status
pill ("Configured (40 chars)" / "Not set (anonymous)"),
storage-location hint. Trimmed token length only — the
secret never round-trips back into the UI after save.
- EN + DE ARB entries (`hubAuthToken*`) + regenerated
`app_localizations.dart` keep the bilingual surface
consistent.
The hub side (auth.tokens config + tower middleware) shipped
on the platform side 2026-05-28 (43a54a2). Until now an
operator had no GUI path to consume it: they had to find the
file in their home dir, paste the token by hand, and bounce
Studio. This panel closes that loop.
Bumped pubspec to 0.47.0. dart analyze clean (No issues
found!); flutter test green (11 tests pass).

Studio's Doctor page _ModulesPanel now shows the source
breakdown directly under the module/capability count:
Modules: 6 loaded, 10 capabilities
6 bundle · 3 mcp · 1 system
Reads `CapabilityEntry.sourceKind` (Phase D wire field).
Pre-0.12 hubs return empty sourceKind; the breakdown panel
falls back to grouping by the legacy `kind` string so older
deployments still see a useful count.
Two data-layer additions:
- `DoctorSnapshot.capabilitiesBySource: Map<String, int>`
- `_sourceBreakdown(Map<String, int>) -> String` renders
the line in deterministic alphabetical order.

Studio's `_sourceForItem` now prefers the wire-level
`sourceKind` field (populated by 0.12+ hubs) over the legacy
name-prefix heuristic. Adds a "temporal" bucket alongside
"mcp" / "n8n" / "native" / "federated" so SPARK-federated
workflows render with their own transport pill on the store
grid + filter chip.
Pre-0.12 hubs return empty `sourceKind` and the legacy
sniffing path still works -- back-compat preserved.
`StoreItem` data class accepts an optional `sourceKind`
parameter (defaults to empty). dart analyze green.

Studio's UI-side `CapabilityInfo` record now carries the
three fields that the F∆I 0.12.0 hub exposes on
CapabilityEntry:
- `provider` — publisher identity ("fai", "fai.system",
"bmds.spark", ...)
- `sourceKind` — transport ("bundle", "system", "mcp",
"n8n", "temporal", "webhook")
- `versionAdvisory` — true for federation sources whose
version pin is a label, not a contract
`allCapabilities()` populates them from the freshly-regenerated
protobuf bindings. Defaults are backward-compatible (empty
strings + false) so a pre-0.12 hub still works against this
Studio build.
Badge rendering in the capability picker / store grid lands
in a follow-up Studio commit; this change is the data-layer
plumbing only. dart analyze green.

Two pieces of the Studio plugin host:
- `data/theme_plugin.dart`: discovery, persistence, ColorScheme
translation. Plugins listed via list_capabilities filtered
to studio.theme.*; selection persisted in SharedPreferences;
loadThemePluginSchemes builds a ColorScheme pair from the
plugin's 14 ARGB tokens per brightness.
- `main.dart`: StudioApp gains themePluginNotifier +
setThemePlugin(). MaterialApp wraps a FutureBuilder that
re-fetches the plugin's ColorSchemes whenever the
capability flips; falls back to FaiTheme.light/dark on
null or load failure.
- `fai_settings_dialog.dart`: new `_ThemePluginPanel` shows a
dropdown of installed studio.theme.* capabilities + a
"Built-in" entry. Switching applies immediately.
- HubService.invokePluginTranslate added as the typed wrapper
for the new gRPC RPC — ready for the FaiEnBadge swap-out
in the next iteration.
- 4 new l10n keys (themePluginHeader / None / Hint / Empty),
EN+DE.
flutter analyze + flutter test (widget + friendly_error): both
green. The integration test for the theme picker is the
existing fai_runtime plugin_theme + Studio-side
invokePluginTheme path that round-trips through the new
mirror-installable studio-theme-solarized bundle.

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`.

Documentation system (the original "whole docs system is broken"
complaint):
- Studio reads inline docs from disk via the new
getInstalledModuleDocs RPC. No network, no auth, no provider
lock-in.
- store.dart probes for MODULE.md eagerly when a module-detail
sheet opens (a single file stat). The Documentation section
only renders when the bundle actually shipped docs.
- Shared FaiTheme.markdownStyle helper used by Welcome's
DocReaderSheet and Store's DocsPanel so every inline doc
reads in the same typography. The shared style forces
code.backgroundColor = transparent to suppress the per-span
bands flutter_markdown's default code style draws on dark
themes.
Flow run dialog:
- Run-button gating now strips the @version suffix from
installed capabilities before the contains() check. Without
this fix the button stayed disabled for every flow with
dependencies, even after a successful install.
- Studio derives a MIME type from the picked file's extension
(small per-suffix map; .pdf, .docx, .txt, .json, ...) and
forwards it to the hub. Fixes "unsupported MIME type:
application/octet-stream" from text.extract.
- Dialog title tracks the future's state: running -> "extract
laeuft", success -> "extract -- Ergebnis", failure ->
"extract -- fehlgeschlagen".
- Output rendering moved from String stringification to a
sealed FlowOutput type (Text / Json / Bytes / File / Unknown).
A new FaiFlowOutput widget dispatches per variant: markdown
for text/markdown (heuristic), pretty JSON for proto Struct,
inline image preview + Save-As for bytes, Open for file URIs.
Byte sizes:
- New humanBytes() helper renders 23.3 kB / 1.04 MB style values
with three significant digits, matching Finder / GNOME Files.
Wired into flow-card pills, picked-file readouts, and the
bytes-payload preview line.

Three Stefan-found bugs in one pass:
1. Documentation rendered in English even when Studio was set
to German. _loadDocs now passes Localizations.localeOf(...)
to fetchModuleDocs(); the hub tries README.de.md before
README.md when locale='de'.
2. 'Keine Treffer' flickered on every keystroke. _onAskTyping
used to call _runSearch synchronously per character — a
short 2-3-letter substring matched nothing, so the empty-
state showed for a frame, then the next character revealed
results. Add a 250ms typing debounce (Timer + cancel on
dispose) so the search only re-runs once typing pauses.
3. Submit button did substring search even when System-AI was
enabled — the _looksLikeQuestion heuristic only routed
4+-word / question-mark queries through the LLM. The user
reasonably expected an explicit submit (with the AI-icon
showing on the button) to actually use AI. New behaviour:
when system-AI is enabled, the submit button always calls
_runAiQuery; live-typing keeps substring filtering. The
heuristic helper was removed (now unused).

UI parity with the platform CLI: `fai reset` (v0.10.93) is now
reachable from Settings. The panel shows the reset blurb plus
two checkboxes mirroring the CLI flags (Keep modules / Keep
audit log + saved flows), then a destructive-styled "Reset hub
state" button. Click goes through a confirm dialog before
SystemActions.faiReset is invoked.
After the CLI returns, Studio bounces its gRPC channel against
the same endpoint (the daemon restarts on the same channel +
port, so no Settings change needed) and reloads every panel:
channel status, system AI, MCP clients, n8n endpoints, registry
token. Output (success or failure) is shown in a copyable error
box so any unexpected stderr lands somewhere the operator can
paste from.
Sits at the bottom of the dialog under "HUB MAINTENANCE",
separated from the everyday config so a destructive button
doesn't crowd the day-to-day controls.
