The Settings dialog was a single 800-line vertical scroll — Hub
endpoint, channels, System AI, MCP, n8n, registry credentials,
hub auth token, default scope, theme plugin, maintenance all
stacked. Stefan: 'inzwischen zu unübersichtlich als langes
feld, untergruppierungen wären toll, wie z.B. in den MacOS
Einstellungen'.
Splits the panel into six focused categories driven by a
left sidebar:
- **General**: Hub endpoint (host/port/TLS), channels,
default scope
- **Appearance**: theme plugin picker (applies instantly)
- **System AI**: operator-managed LLM endpoint for Studio
helpers
- **Integrations**: MCP servers + n8n endpoints
- **Security**: registry credentials + hub auth token
- **Maintenance**: reset / destructive ops
Sidebar uses macOS-style icon + label rows with a highlighted
selection pill. Content area is per-category, scrollable
within its own panel. The dialog widens from 520→820 px and
gains a fixed height (620 px) so the layout doesn't jump as
the operator switches categories.
Each panel opens with a title + one-sentence description so
the operator knows what they're looking at before scanning the
controls — same pattern Apple uses in System Settings.
Also adds the missing 'meta' dependency that FaiLog's
@visibleForTesting needed. Studio bumped to 0.63.0.

FaiLog used to compute its destination directly from HOME, which
made it impossible to test without scribbling on the operator's
real ~/.fai/logs/. Adds a static testPathOverride seam tagged
@visibleForTesting so the singleton can be redirected at a per-
test temp file.
The new test/fai_log_test.dart covers:
- append() writes one JSON-shaped line per event
- context field round-trips when supplied
- tail() returns oldest-first
- tail(maxLines:) caps and keeps the newest entries
- rotation moves the previous log to .log.1 past 256 KiB
- path getter honours the override
- writes to an impossible path do not throw — best-effort
contract that protects the UI from log-write failures
Production behaviour is unchanged: when the override is null
the path getter still computes from HOME/USERPROFILE.

Two operator-visible fixes prompted by 'I picked a theme but
nothing changed':
- Theme picker tile taps now show a brief "Theme applied:
<name>" snackbar — the picker applies themes instantly, so
the operator needs a confirming cue. Slow `_pluginThemes`
loads no longer read as "click did nothing".
- `_pluginThemes` failures (plugin unreachable, manifest
drift, etc.) write to `FaiLog` so `fai admin doctor` and
Studio's inline log viewer can surface them. Previously
swallowed silently, which is what made debugging this so
miserable.
- Settings dialog's primary button relabelled to
"Connect to endpoint" (was "Save & connect") so operators
don't mistake it for "save my theme choice". The theme
selection persists at tile-tap time; the Settings dialog
has nothing left to "save".
- Theme section header gains an explicit "(applies instantly)"
cue for the same reason.
Also fixes a pre-existing curly-braces lint in the n8n add-
endpoint dialog. Studio bumped to 0.62.1, editor pinned via
path override at 0.15.1.

Bundles the error-UX overhaul and the inline log viewer:
- New `FaiLog` (`~/.fai/logs/studio-errors.log`, 256 KiB rotation,
JSON-per-line). Every operator-visible failure is appended so
`fai admin doctor` and the new viewer can show the trail
without the operator having to reproduce the failure.
- New `showFaiErrorSnack` / `showFaiErrorDialog` helpers wrap
`FaiErrorBox` in copyable surfaces; 27 ad-hoc
`SnackBar(content: Text(e.toString()))` sites swept to use
them (settings, doctor, audit, store, module sheet, system-AI
editor, flow output).
- New `FaiLogViewer` modal (`showFaiLogViewer`) renders log
files inline with line numbers, JSON-key + `[level]` token
colouring, Copy-all, Refresh, Open-externally. Doctor's
daemon-paths panel grows a "View" button next to "Open" for
every `.log` row and now also lists the Studio errors log.
- Today carousel: CTAs now actually re-run search after a
`filterCategory` / `runQuery` story is tapped (was only
flipping the chip state). Fallback story list bumped to 8.
- Editor bumped to git ref carrying 0.15.0 (type-token
colouring + analyzer diagnostics).
Studio bumped to 0.62.0.

Two visible UX shifts:
1. Store Today carousel.
- Three hardcoded stories rewritten to be generic:
'Modules are the building blocks',
'Flows chain modules deterministically',
'Bring your own sources' — no DeepWiki / Semgrep /
text.extract / extract-summarize.yaml mentions. The
concrete brand suggestions live in Settings → MCP
Clients where the operator goes deliberately.
- +DeepWiki / +Semgrep quick-add chips removed from
the hero footer. They felt like ads on every page
load. The standalone Suggested Sources strip below
still picks them up, but the editorial hero stays
clean.
- Auto-hide the entire carousel once installedCount
≥ 3 — the operator has demonstrably been here
before; the welcome strip stops earning its scroll
cost.
2. Editor bump to 0.13.0:
- Edge selection (click a wire to select it)
- Properties panel edge-info mode with type-compat
indicator + Disconnect button
- Canvas-wide background tap closes the panel (works
even when zoomed out so the grid doesn't fill the
viewport)

Three changes:
1. Onboarding checklist hints no longer mention DeepWiki,
Semgrep, text.extract, or extract-summarize.yaml by
name. Brand- and file-specific copy moved to neutral
feature pointers ('add an MCP source', 'install a
module'). Brand names belong on the welcome page only
if they're load-bearing for understanding, which they
aren't.
2. Checklist rows are now clickable. Tapping a row navigates
to the page where the operator can complete it — MCP +
AI open Settings, Module opens Store, Flow opens Flows.
StudioShellState gains a public navigateTo(pageId) helper
so descendants can drive sidebar selection without
plumbing a controller through props.
3. Theme picker hint copy rewritten. Old hint suggested
'Custom' was a single-colour tweak; new copy spells out
that Material 3 derives a full palette (primary,
secondary, tertiary, surface, …) from one seed colour.
The Custom tile shows a small tune icon so its
open-the-picker semantics is visually distinct from the
apply-immediately plugin tiles.
Editor bumped to 0.12.0 (panel toggle + LabVIEW-style port
colours).

Settings dialog's Theme Plugin section is now a grid of
swatched tiles:
- Built-in (none) — falls back to FaiTheme.light/.dark
- One tile per installed studio.theme.* plugin, each
showing the plugin's primary/secondary/tertiary as
live colour dots. Tile loads its preview lazily so a
dozen installed themes don't block the picker.
- Custom — opens a colour-picker dialog with 12 curated
Material presets + a hex input + live preview. Selecting
applies ColorScheme.fromSeed for both brightnesses.
main.dart's _pluginThemes parses a 'custom:#RRGGBB' sigil
in the same notifier slot as plugin capability ids, so the
existing persistence + restoration paths cover the custom
case with no new state.

additional canvas patterns ported from jai_client.
- fai_client_sdk 0.18.0: regenerated ModuleField bindings

Wires StudioFlowRunDriver.moduleInfo so the editor can
fetch declared field info per step capability. The hub
maps schema_version 3 manifest fields (inputs/outputs
with description.en/de) through ModuleInfoResponse; this
patch wraps them back into the editor's ModuleSpec /
ModuleField vocabulary so the canvas paints them as
distinct anchors with hover tooltips.
ModuleDetail in hub.dart now carries the same inputs +
outputs lists (with ModuleFieldInfo type + i18n
description map), enabling other Studio surfaces — e.g.
the module-detail sheet — to render bilingual field docs
in a later pass.
Plus: store-doc nested-scroll fix. The module detail
panel's docs section sat inside its own 480px viewport
inside the outer sheet's SingleChildScrollView, producing
the double-scrollbar feel. Setting
physics: NeverScrollableScrollPhysics on the Markdown
widget and dropping the maxHeight lets the docs scroll
as part of the outer sheet — one scrollbar, predictable
mouse-wheel behaviour.

The 1440x900 default felt too wide for first-run: the
Welcome page's 960 px content column left visible slack on
either side even after the centring fix, and the editor's
sidebar plus canvas plus properties panel still didn't
need that much horizontal room on a fresh open.
1280x900 matches the most common laptop effective
resolution, keeps every Studio surface comfortable, and
the operator can resize larger any time. Same value
across all three host platforms (macOS NSWindow setContentSize,
Linux gtk_window_set_default_size, Windows Win32Window::Size).

Welcome page used ConstrainedBox(maxWidth: 960) inside a
left-aligned Column, so on the 1440x900 default window
the content hugged the left edge and left ~370 px of
empty space on the right. With Stefan's M4 sidebar
collapsed to 72 px the asymmetry was the dominant visual
in the first thing every operator sees.
Wrap the ConstrainedBox in a Center widget. 960 px stays
an opinionated reading width — long-form prose gets
uncomfortable past ~1100 px — but the slack now splits
evenly so the content sits with ~190 px breathing room
on both sides instead of all on one.

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.
- lib/pages/flows.dart — replaced with a 50-line wrapper
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

Stefan observed the default Studio window opened smaller
than comfortable when launched fresh (no persisted size).
On macOS specifically the xib-stored default was around
800x600 — too tight to read the sidebar + content + run
panel side-by-side.
Set 1440x900 as the initial content size across all three
host platforms:
- macOS: MainFlutterWindow.swift sets contentSize via
NSWindow.setContentSize after the FlutterViewController
attaches, and centers on the active NSScreen. Clamped to
the screen's visibleFrame so we never open larger than
the display (matters for non-Retina external monitors).
- Linux: gtk_window_set_default_size 1280x720 -> 1440x900
- Windows: Win32Window::Size 1280x720 -> 1440x900
1440x900 is the effective Retina resolution of a 13" MacBook
(Stefan's dev machine) and the smallest "modern desktop"
footprint that lets the sidebar + content + tool panel
breathe.

Signed-off-by: flemming-it <stefan.a.flemming@googlemail.com>
The earlier "single AnimationController for width + opacity"
commit (0.51.5) made the *visual* expand smooth but the
underlying layout still jumped because the rows themselves
changed height between states:
collapsed expanded
───────── ─────────
triangle (36 px) triangle + 2-line title (44 px)
dot (10 px) dot + multi-line pill with
optional "Start hub" button
(60-80 px when disconnected)
letter (16 px) letter + accented chip (28 px)
So everything BELOW the header — destinations list, footer —
slid down ~50 px every time the rail opened. That's the
"Versatz" Stefan kept seeing. Fading the labels in didn't
help; the row geometry was the wrong source of truth.
Structural fix: every header row is now a SizedBox with a
fixed pixel height. Collapsed-state and expanded-state
content both fit inside the same height:
_brandRowH = 48 // FaiDeltaMark (36 px) centered
_connRowH = 44 // single conceptual block, two single-
// line texts, no multi-line pill
_channelRowH = 28 // chip + single-line channel name
_rowGap = 8
The total header block is therefore a constant pixel sum.
Items below it (the destinations ListView, the footer) sit
at the same Y in both states by construction — not by lucky
math, not by animation tricks. The width animation only
moves the rail's RIGHT edge; the left + top + bottom edges
of every row are immovable.
To make the connection row fit in 44 px we drop the inline
"Start hub" tonal button. The same affordance is preserved
by making the whole row tap-handled when the daemon is
unreachable: tap the red dot (or anywhere on the row) to
fire `fai daemon start`. The tooltip is updated to spell
this out ("Disconnected · tap to start · …").
The channel row is now ALWAYS reserved (28 px placeholder
when no channel is active) so that flipping the operator
config from local→dev at runtime doesn't shift the
destinations list either. The placeholder is invisible.
Side-effects:
- _ConnectionPill is removed (nothing references it).
- New _BrandLabel + _ConnectionLabel widgets, both
trivially Column(MainAxisAlignment.center, …) so their
content sits visually centered inside the fixed row.

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.

+ label opacity in lockstep (no more glitchy expand)
The previous "fixed-width icon column" commit already locked
the icon's horizontal pixel-X, but the rail still _felt_
glitchy on expand because the rail's geometry and the rail's
content were animated by two different mechanisms:
- Width: AnimatedContainer over FaiMotion.fast (120 ms)
- Content: setState(_hovered = true) → conditional
`if (expanded) Expanded(label)` snaps in one frame
So on mouse-enter the label widget appeared INSTANTLY while
the rail was still 72 px wide. The label tried to render in
0 px of available space and Flutter's layout engine clamped
it; over the next 7 frames the rail grew to 220 px and the
label visibly "settled in". That's the perceived glitch.
Replace the two-source animation with a single
SingleTickerProviderStateMixin + AnimationController whose
value `t` (0..1, eased via easeInOutCubic) drives both:
- rail width = lerp(72, 220, t)
- label opacity = t
- labelsInteractive = t > 0.5 (so hidden buttons can't
eat clicks meant for the icon column)
Labels are wrapped in `t > 0 ? IgnorePointer(Opacity(...))
: SizedBox.shrink()`. Once the animation starts, the label
joins the tree at opacity ≈ 0 (invisible — no pop) and
fades up smoothly as t grows. When fully collapsed (t == 0)
the label is removed from layout entirely, so the connection
pill's tall "Start hub" affordance doesn't inflate the
collapsed rail's height (this also fixes the widget_test
vertical-overflow that 0.51.4 introduced).
Same pattern applied to the footer (settings icon stays in
the 72-px column always; theme/lang/clock fade in beside it)
and to each _SidebarItem destination row.
End result: width AND content travel together along the same
animation curve. No more "snap then catch up" — they're
mathematically inseparable.

Previous "left-anchor everything via padding" approach made
the math work on paper but the perceived shift persisted. The
root cause was structural, not padding-based: ListView gave
each item a tight cross-axis constraint equal to the rail's
current width (48 collapsed, 196 expanded). Inside the item,
the AnimatedContainer filled that constraint and laid out a
mainAxisSize.min Row at the start of the AC's content area.
The icon's pixel-X depended on the AC's padding _and_ the
constraint; even with equal padding the rendered layout
shifted across the expand animation because Flutter
re-resolved alignment under a moving constraint.
Replace the entire pattern with a fixed-width icon column
that doesn't care about the parent constraint:
ListView (padding 0) → Item Row
SizedBox(width: 72) → Center → icon ← anchored to literal x
if expanded → Expanded → label text ← grows into remaining space
Same pattern for the brand/connection/channel rows above. The
72 px matches the rail's collapsed width exactly, so collapsed
rail = one icon column + nothing; expanded rail = same icon
column + label slot. Icon's pixel-X is now provably constant.
Removes the AC's horizontal padding entirely — the icon
column owns the left anchor. The background highlight still
spans the full row width (typical nav-rail UX), and the rail
expand animation only moves the rail's right edge, never any
icon-bearing element.
Also passes an `iconColumnWidth: 72` to _SidebarItem instead
of hard-coding the magic number in two places.

Two Stefan-reported fixes after the v0.51.x live test:
1. Sidebar icons appeared to shift between collapsed and
expanded. Mathematically the icons stayed at x=24 (
ListView padding + AC padding), but the Column's default
crossAxisAlignment.center re-centered the brand mark
AND the top indicators (version, connection, channel) on
every expand → in a 72 px rail the brand sits at x≈36,
in a 220 px rail it sits at x≈110. Stefan perceived this
horizontal repositioning of the brand+pills as a shift
of the icons below.
Fix: Column.crossAxisAlignment = start + left-pad every
top item (brand mark, "F∆I Studio" label, version,
connection pill, channel pill, mini-version, connection
dot, channel chip) by exactly the same offset the
destinations use (ListView.padding + AC.padding =
FaiSpace.md + FaiSpace.md). The whole rail now reads as
one stable left edge through the expand animation.
2. Pull fai_studio_flow_editor 0.1.2 — fixes the
"opening hello.yaml shows extract-with-approval content"
bug by switching `_code.text = ...` to the canonical
`_code.fullText = ...` setter in the package.

Updates fai_studio_flow_editor pin from 51f9a1d to 8b918f8.
Upstream fix: the editor's dirty-detection compared
_code.text against a snapshot taken before CodeController
normalisation, so opening any flow whose loaded text the
controller silently rewrote (trailing-newline handling, YAML
fold markers, line-ending normalisation) immediately read as
dirty. Clicking a different file in the list then raised the
"Discard unsaved changes?" prompt even though the operator
hadn't typed anything.
The package now compares _code.fullText (the canonical
post-processed value) against a baseline captured AFTER the
text assignment. Comparing fullText-to-fullText eliminates
the spurious diff.

Two UX bugs Stefan flagged on the v0.51.0 collapsible rail:
1. Icons re-positioned when the rail expanded. Operators
already pointing at an icon had to chase it as the rail
grew. Two causes: the _SidebarItem switched between
`Center(icon)` (collapsed) and `Row(icon, gap, label)`
(expanded), and the AnimatedContainer's horizontal padding
switched between FaiSpace.sm (collapsed) and FaiSpace.md
(expanded). Both flipped the icon's effective X-position.
Now: same Row, same AnimatedContainer padding, in both
states. The icon sits at the same X-pixel always; only
the label slot toggles open beside it.
2. Top of the collapsed rail was wasted (only the brand-mark
was visible; version + connection + channel disappeared
completely). Use the same vertical real estate for
glance-able compact equivalents:
* tiny "v0.51" version text in mono below the brand
* _CollapsedConnectionDot — 10 px circle, green/red/amber
tonality matching FaiDeltaMark's mode states. Tooltip
surfaces the full endpoint string.
* _CollapsedChannelChip — 18 px circle with the channel's
first letter (P / B / D / L) in the same accent tone
the full pill uses, so "production" stays unmistakably
red even at-a-glance.
When the rail expands, the full pills replace the compact
indicators as before. Tests still green (the existing widget
test booted without hover-expand and that path stays correct
either way).

The flow editor was internal to Studio (lib/pages/flow_editor.dart).
Per Stefan's review feedback ("austauschbar wäre schöner"),
extract it into its own Forgejo repo so the host can swap
the implementation without touching Studio.
New repo: https://git.flemming.ai/fai/studio-flow-editor
Studio's pubspec.yaml now references the package by git URL:
dependencies:
fai_studio_flow_editor:
git:
url: https://git.flemming.ai/fai/studio-flow-editor
ref: main
To swap the editor:
1. Fork (or write a new) fai/studio-flow-editor.
2. Keep the FlowEditorPage(initialFlowName, locale, onRun)
constructor signature — the stable host contract.
3. Point the pubspec at your fork.
4. Rebuild Studio.
Adapter pattern: _FlowEditorAdapter in main.dart resolves the
package's runtime dependencies (locale via Localizations,
onRun via HubService) from the BuildContext, then constructs
the package's FlowEditorPage. Same pattern in flows.dart for
the pencil → editor route push, so a future operator-side
locale switch propagates correctly.
The package brings its own copies of FaiSpace tokens, minimal
FaiEmptyState/FaiErrorBox widgets, and an inline EN+DE l10n
table — accepting a small amount of visual drift in exchange
for true package independence. flutter_code_editor +
highlight move from Studio's pubspec to the package's.
Deleted:
lib/pages/flow_editor.dart → package's lib/src/flow_editor_page.dart
test/flow_editor_test.dart → package's test/ (next commit there)

Three operator-visible improvements per Stefan's review of
the v0.50.0 editor.
1. Pencil icon on Flows page now opens Studio's own flow
editor (route push) preloaded with the selected flow,
replacing the previous "open in OS default editor"
(SystemActions.openInOs) behaviour. The editor's AppBar
gains a back arrow when reached via route push; reaching
the editor via the nav rail leaves it bare. Tooltip
string updated in EN + DE.
2. New FlowEditorPage `initialFlowName` parameter. When set,
the page loads that flow on first frame (via post-frame
callback so the BuildContext is mounted before
_openByName runs). When null (the nav-rail path), the
editor opens to its empty state as before.
3. Sidebar (_Sidebar) is now collapsed-by-default: shows
just icons in a 72px-wide rail with per-destination
tooltips. Hovering the rail expands it to 220px (the
old width) with brand-mark + labels + the full footer
row (theme toggle, language toggle, clock, settings).
Collapsed footer shows the settings icon only. Brand-
mark (FaiDeltaMark) stays visible in both states so the
live/idle status dot is always glanceable.
Side-effect: SystemActions import in flows.dart is no
longer needed (the pencil no longer shells out) — removed.
widget_test.dart: dropped the per-destination Text-presence
asserts since labels are now Tooltips when collapsed.
Hover-expand testing triggers RenderFlex-overflow mid-
animation in widget tests (the AnimatedContainer's width
transitions through a constraint slimmer than the Row's
intrinsic min). The booting-without-throwing assertion
remains; per-destination presence stays in the per-page
test suites.
Both arb files updated with the new strings (navFlowEditor
already existed; added flowEditorBackTooltip + retouched
flowsOpenInEditorTooltip).

Previously a failed runSavedFlow dumped the raw exception
into FaiErrorBox in the right panel. Hub gRPC failures
(network, missing module, schema reject, …) are now mapped
through friendlyError so the operator sees a one-sentence
headline + optional recovery hint, with the verbatim error
still accessible behind FaiErrorBox's expand-on-tap.
Matches the same pattern already used by every other Studio
page that surfaces a hub error.

Wraps the FlowEditorPage in Shortcuts/Actions so
Cmd+S (or Ctrl+S) saves and Cmd+Enter (or Ctrl+Enter) runs
the active flow, no matter whether the code field or
toolbar has focus. Matches the rest of Studio's keyboard-

New top-level destination "Editor" (Cmd+5) ships as Studio's
fifth surface. The editor reads + writes flow YAML directly
under ~/.fai/data/flows/ via dart:io — the hub picks up the
changes on the next listFlows / runSavedFlow call.
Layout: two-pane shell. Left (240 px) is the file list; right
flexes to the code pane and an optional results column when
Run produces output. Top toolbar exposes:
* filename + dirty-mark
* New flow (scaffolds from a debug.echo template)
* Save (writes the active file to disk)
* Run (saves first if dirty, calls
HubService.runSavedFlow, surfaces typed FlowOutputs in
a side panel)
* Refresh
YAML highlighting via flutter_code_editor + the highlight
package's yaml language. Lightweight style map mapping the
five token classes that actually appear in flow YAML
(attr / string / number / comment / subst for the
${{ ... }} template syntax) to FaiTheme colors — keeps the
editor visually consistent with the rest of Studio.
New-flow naming uses a FilteringTextInputFormatter that
restricts the name to [a-z0-9_-]. A "name already exists"
SnackBar surfaces the conflict instead of silently
overwriting.
Bilingual strings shipped (en.arb + de.arb) for every
operator-facing string: toolbar buttons, dialogs, empty
states, file-exists error, run-output header.
New deps:
* flutter_code_editor ^0.3.5
* highlight (transitive — pinned as direct so the
yaml-language import has its declared dependency).
Smoke-test (test/flow_editor_test.dart) pumps the page and
asserts the empty-state + toolbar render without throwing
on hosts that don't have ~/.fai/data/flows yet. The full
file-list + open-on-tap flow needs a writable HOME override
which dart:io's read-only Platform.environment doesn't allow
inside a test isolate — that path lives in the integration
suite as a follow-up.
Version bumps:
* pubspec.yaml: 0.49.1 → 0.50.0
* main.dart kStudioVersion: 0.42.0 → 0.50.0 (had drifted
behind pubspec; brought back into sync as part of this
bump)

The doc-reader bottom-sheet in welcome.dart hits rootBundle
to load assets/docs/<slug>[_de].md. When the asset isn't in
the bundle (e.g. the binary on disk predates the
flutter_markdown_plus migration in 69b54629 or an in-progress
asset reorganisation), the FutureBuilder's error branch dumps
the raw PlatformException text into FaiErrorBox with no
hint at what the operator should do.
Switch the throw to a structured `_DocReaderError` that
carries:
- the slug, locale, and both attempted asset paths
- the underlying error message
- a precomputed `forgejoUrl` pointing at the same doc on
the platform repo's main branch
The error UI gains a TextButton.icon below FaiErrorBox that
opens the Forgejo copy in the OS browser via the existing
SystemActions.openInOs path — operators always have a
working out, even when the local bundle is broken.
The error toString() also surfaces "rebuild Studio" as the
top suggestion, since the most common cause for asset
mismatches is a stale binary running against a newer source
tree.
New regression test (test/load_docs_test.dart) pumps the
exact code path the sheet uses (rootBundle.loadString +
Markdown with FaiTheme.markdownStyle) against all eight asset
paths (architecture/security/audit/flows × en/de). Catches a
future bundle drift before an operator notices.
No behavioural change on the happy path. Both the rendered
markdown widget and the closed-sheet animation are unchanged.

`hub_auth_token.dart` write() previously did
await f.writeAsString(token); // file is now 0644 (umask)
await Process.run('chmod', ['600', f.path]);
which leaves a TOCTOU window where the file is world-readable
between the writeAsString and the chmod call. On a multi-user
host another user could read the bearer token during that
window.
New flow:
await tmp.writeAsString(token); // .tmp file
await chmod(600, tmp.path); // restrict mode FIRST
await tmp.rename(f.path); // atomic POSIX rename
The destination is never visible with permissive perms. Also
sets `~/.fai/` itself to 0700 on Unix on first creation so
other users on a shared host can't enumerate the directory.

Lifts every direct dependency Studio carries to its latest
available version:
fai_client_sdk: 0.16.0 → 0.17.0 (grpc 5, protobuf 6, new

+ the SDK major dragged dbus 0.7.13, xml 7.0.1, analyzer
13.0.0, _fe_analyzer_shared 100.0.0 via the constraint

What Studio's call sites needed in code: nothing. `HubClient`

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.

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
