chain-studio/CHANGELOG.md

# Changelog

All notable changes to `chain_studio` recorded here. Pubspec
version + `kStudioVersion` in `lib/data/about_info.dart` stay in
lockstep.

## Unreleased

### Added — real trust + exposure data (0.77.0)

- **Per-entry install verification.** The hub now reports (since
  0.23) how an install of each store entry would be verified under
  the CURRENT policy — computed with the same resolvers the install
  gate enforces, so display and enforcement cannot disagree. The
  trust-gate dialog replaces its generic "no per-entry status yet
  (alpha)" note with the classified statement: signature checked
  via pinned store key / trusted publishers (green), installs
  without signature checking (amber, policy off), install would be
  refused (red), or bridge entry without a bundle signature. Store
  cards stay quiet on the good path and wear an "unsigned"/
  "blocked" warning pill only when installs are unverified —
  same philosophy as the provenance pill. Against a pre-0.23 hub
  everything keeps the old honest wording.
- **Service exposure on the doctor page.** Every declared host
  service shows its network reach as classified by the hub from
  the endpoint host (local only / private network / publicly
  reachable / reach unknown — no DNS lookups). Publicly reachable
  endpoints get the warning tone with a "make sure it is
  protected" hint.

### Added — explain it where it happens (0.76.0)

- **In-place help pattern.** New `ChainInlineHelp` (a one-sentence
  intro strip that says what a surface is and what will happen, with
  an optional "Learn more" link into the doc sheet) and
  `ChainFieldHelp` / `ChainFieldLabel` (a "?" affordance for a single
  field). First applied to the add-satellite dialog, which used to
  ask for a "name" with no hint of what a satellite even is
  (usertest): it now leads with a plain explanation + a federation
  "Learn more", and the name field carries a "?".
- **Page help opens the RIGHT topic.** The Federation and Runs help
  buttons silently fell back to the architecture doc — `federation`
  and `runs` had markdown assets but no catalog entry, so
  `showFaiDoc` resolved them to the first doc. Both are registered
  now; a new `doc_help_wiring_test.dart` asserts every
  `showFaiDoc('slug')` call has a registered entry AND both locale
  assets, so a help button can never open the wrong topic again.

### Security (0.75.0)

- **Sealed-area names are confidential by default.** The workspace
  switcher no longer lists sealed areas by name on a casual glance
  (names often carry client/mandate identity — usertest security
  finding): it shows one aggregated row ("2 sealed areas") and
  reveals the named rows only after a deliberate click, per menu
  opening. Settings → Security offers "list sealed areas with
  their names right away" for single-operator machines.

### Changed (0.75.0)

- **One segment control everywhere.** The same single-select
  choice pattern used to appear as four different widgets: the
  audit page's hover pills, the store's Material SegmentedButton
  (Modules / Studio & Designs), the store filter dialog's
  ChoiceChips and the approvals page's TabBar. All of them now use
  the canonical `ChainSegments` pill control (the audit pattern
  promoted to a shared widget, with icons and a11y semantics);
  the approvals page keeps both lists alive in an IndexedStack so
  switching does not refetch. A canon-guard test bans
  TabBar/SegmentedButton/ChoiceChip from lib/ for good. Guide
  images + wording updated (dark and light verified).

### Hardening round (test strategy, 2026-07-19)

- **Hermetic widget suites.** `HubService.instance` is injectable;
  a scriptable fake (`test/support/fake_hub.dart`) answers every
  member the pages touch and scripts per-RPC failures. The a11y and
  responsive sweeps run against it — results no longer depend on
  whether a hub happens to listen on the operator's machine (which
  was the root of the historic a11y flake).
- **State-matrix sweep** (`state_matrix_test.dart`): every sidebar
  page × hub condition (healthy / gone / too old / feature off) with
  app-wide invariants — no "unreachable" claims while the hub
  answers, no raw error text in the UI, classified states only.
- **Shared load-error view.** Store, Doctor, Audit, Approvals and
  Federation no longer fold every load failure into "hub not
  reachable"; `HubLoadErrorView` classifies into unreachable /
  needs-newer-hub / load-failed-with-copyable-detail (new DE+EN
  strings). Also fixed: the approvals page's hidden tab surfaced
  load failures as uncaught async errors; the audit status bar
  rendered the raw gRPC error wall instead of the friendly headline.
- **Version-skew gate.** `integration_test/skew_smoke_test.dart`
  (run via the platform repo's `scripts/skew-smoke.sh`) boots the
  released hub binary and walks every page with the same
  invariants — the dev-Studio-against-old-hub combination is now a
  release gate instead of a live-bug generator.

### Added (0.74.0)

- **Doctor findings deep-link to their page.** Summary tiles and
  panel rows jump to where the finding is actioned: modules → store,
  "approvals waiting for review" → approvals inbox, audit chain →
  audit log (chevron affordance, tooltip + semantics button). The
  host-services empty state gains a "view the configuration" button,
  and the update banner's release-notes URL is a real link now.

### Fixed (0.74.0)

- **Runs page no longer contradicts the sidebar.** Load failures are
  classified instead of all reading "hub not reachable": an older hub
  without the ListInvocations RPC gets "this view needs a newer hub
  version" with a doctor link, the detached-off refusal shows the
  regular feature-off empty state, and unknown errors surface a
  copyable detail box. "Not reachable" is reserved for genuine
  connection failures.
- **Audit page timer leak.** The live-stream reconnect timer is held
  and cancelled on dispose.
- **a11y suite flake killed at the root.** The pending-timer failures
  came from the gRPC channel's 5-minute idle timer being armed when
  the last stream closes; the suite now closes the channel and pumps
  past the idle timeout (6 consecutive full runs green).

### Added

- **Full-history audit export.** The audit page's actions menu gains
  "Export full log as JSONL" next to the current-view export: fetches
  the complete event history of the active project scope (independent
  of the type chip, the search field and the page's 100-event window)
  and writes it as JSONL. The current-view export is unchanged; the
  CLI `chain admin events --json` remains the canonical tool for
  WORM-guaranteed exports (a stale code comment still advertised the
  never-shipped `chain audit export` — fixed).

### Changed (usertest low-findings tail)

- **Honest hero badge.** The store hero wears "TODAY"/"HEUTE" only
  for an operator-accepted story; the compiled-in fallback deck has
  no date binding and now says "FEATURED"/"EMPFOHLEN".
- **Audit filter chips in UI type.** The Alle/Flow/Schritt/Modul
  chips drop the monospace styling — mono stays reserved for paths
  and identifiers.
- **One verb for the chain check (DE).** "Hash-Kette geprüft" is the
  confirmation everywhere (audit header, doctor pill); "intakt"
  remains the state headline. English was already consistent.
- **Readable sealed-area status.** The "stopped" label in the
  workspace switcher gets a modest contrast bump.

### Changed (usertest panel 2026-07-17, 14 personas — all confirmed findings)

- **Install trust gate.** One confirmation dialog before every module
  install (store card, detail sheet, flow quick-fix): source, version,
  license, maturity, required services — plus an honest signature note
  (the hub does not report per-entry signature status yet; no fake
  badge).
- **Settings → About.** Product, Studio + hub version (live), vendor
  Flemming.AI / Dr. Stefan Flemming, Apache 2.0, contact, docs link —
  every value copyable.
- **Discoverable sidebar.** Instant tooltips with the ⌘1–9/^1–9
  shortcut, semantics labels, a visible "Search & commands ⌘K" row,
  and a setting to keep the rail always expanded.
- **Plain-language empty states.** Runs page explains background runs
  in plain words and — via the hub's new `detached_enabled` flag —
  says truthfully whether the feature is off or simply unused;
  approvals inbox explains human approvals without raw capability
  syntax; welcome cards lead with everyday language (tech detail
  behind a toggle).
- **One term per concept.** "Fähigkeiten" is the German lead term
  (welcome, integrations, federation); "Registrierungs-Token" instead
  of "Enrollment-Token"; category and source-kind labels localized
  (no lowercase wire tokens like `document`, `1 system`).
- **Audit page.** Free-text search over the event list; JSONL export
  of the current view; the dev-only clear action moved from a bare
  trash icon into a labeled overflow menu.
- **Doctor page.** Copy button on every daemon path row; "n of m
  events verified" instead of "n/m chain"; hash-chain wording unified.
  The module tile no longer counts the built-in `system`
  pseudo-module (a fresh hub shows 0 modules, matching the welcome
  checklist); the daemon-files panel warns when the audit DB lives in
  an OS-cleanable temp directory; the daemon card states endpoint,
  transport security, and token status (length only) in one line.
- **Federation page.** Primary action in the app bar and in the empty
  state (FAB removed); plain-language empty text.
- **Store.** License pill on the module card; maturity pills explain
  themselves on hover; carousel shows a textual position; German tab
  says "Studio & Designs".
- **Formal address guard.** A test now rejects informal German forms
  including reader-addressed imperatives; literal markdown backticks
  are gone from both catalogs.
- **Setup.** The wizard replaces the Settings dialog instead of
  stacking on it, with a stronger scrim; the try-out profile names
  the upgrade path to a regulated profile.
- **Welcome checklist.** The "start a saved flow" tick is sticky
  instead of silently unticking once the event leaves the
  recent-events window.

### Changed (setup lives before the app)

- **First-run gate.** A fresh install starts inside the setup: a
  dedicated screen hosts the wizard before the app appears (embedded
  mode + explicit "Später einrichten" skip). The Welcome page loses
  its setup button entirely; re-running the setup lives in Settings →
  General ("Run setup again…"). Wording de-ad-ified: "Einrichtung
  starten" instead of "In 3 Fragen loslegen".
- **Preview before permission.** The plan preview now calls the new
  PlanSetup RPC over the live hub connection instead of spawning the
  chain CLI — whose first run could pop the macOS file-access prompt
  BEFORE the operator ever saw the plan. CLI remains the no-hub
  fallback; applying stays the explicit separate step.
- **Native file dialog for flow file inputs** (with flow-editor
  v0.23.0): the Run tab's file inputs open a real picker; typing an
  absolute path is now only the no-host fallback.


### Fixed (startup + build time)

- **Black window on launch.** A corrupt preference value (`hub.secure`
  stored as int `0` by an external `defaults write`) made
  `SharedPreferences.getBool` throw inside `main()` before the first
  frame — the app sat as a black window with no visible error. Pref
  reads now tolerate wrong types (int coerces to bool, garbage falls
  back to the default), and every pre-frame restore step is
  failure-isolated so nothing can prevent `runApp` again. Regression
  tests reproduce the corrupt store.
- **CocoaPods integration removed** (macOS). The project builds via
  Swift Package Manager; the leftover Pods wiring (Podfile, `[CP]`
  script phases, Pods framework refs, xcconfig includes) made every
  build run both dependency managers — exactly what Flutter's
  own "will improve the project's build time" warning was about.


### Added

- **Settings → Security shows the hub's auth policy.** New panel
  backed by the hub's read-only `AuthStatus` RPC: active token
  validator (static / JWT-RS256 with issuer, audience and JWKS
  source), anonymous-access warning, and per-token cards with
  scope grants, env-var presence and rate limits — T4/T5 security
  administration finally visible outside YAML. Non-admin tokens
  get a localized denied story instead of an error.
- **Permanent accessibility + responsive test gates.** Every page
  must pass WCAG text contrast and labeled-tap-target guidelines
  in both themes (`test/a11y_test.dart`) and lay out without
  overflow from 800 to 1920 px (`test/responsive_test.dart`).

### Fixed

- **Daemon start with a wrong token no longer misreports.** Both
  start paths (welcome CTA, sidebar) treated an auth-rejected hub
  as "daemon dead" and showed a start-failure dialog while the
  banner above correctly blamed the token; an auth rejection now
  counts as "daemon alive".
- **Token fixed outside Studio heals the connection.** On an
  auth-rejected poll the shell re-reads `~/.chain/hub-auth-token`
  and reconnects when the file changed — following the banner's
  own advice no longer requires re-saving in Settings or a
  restart. An endpoint switch also resets the failure streak, so
  a stale in-flight probe can't blame the new endpoint.
- **Security panel stays fresh.** The auth-policy view re-queries
  after saving or clearing the hub token in the panel above, and
  renders the hub's new `reload_required` flag as a plain-language
  pending-reload warning (DE+EN).
- **Auth-rejected hub no longer reported as "unreachable".** With
  token auth active, a wrong or rotated token got UNAUTHENTICATED
  from a perfectly reachable hub, but the sustained-failure banner
  said "can't reach the hub" — pointing the operator at the
  endpoint instead of the token. The shell now probes with the
  SDK's failure-kind-aware `probe()` and switches the banner to
  "rejected the sign-in — check the access token" (key-off icon).
- **Light theme accent was below WCAG contrast.** Filled buttons
  and the active sidebar label rendered white-on-sky-500 (2.8:1);
  the light scheme now uses sky-700 (~5.9:1). FABs follow the
  same accent instead of Material 3's tonal default.
- **Audit page at narrow window widths.** The app-bar filter chips
  collapse into a checkmark menu below 900 px, and the live-status
  bar shrinks gracefully (copyable disconnect error gets the full
  row width).
- **Consistent formal address in German.** ~20 strings still used
  du-forms next to the Sie-forms on welcome/setup; the audit
  event-type chip "Step" is now "Schritt"; the doctor page's event
  count pluralises correctly ("1 Ereignis") in both languages.
- **Stored tokens reached the wrong directory.** `~/.fai/` rename
  leftovers: the hub-auth token and registry token were read from /
  written to `~/.fai/` while the hub reads `~/.chain/` — a stored
  registry token never reached the hub. Today-stories and UI texts
  still advertising the retired `.fai` bundle extension fixed too.

### Fixed (wizard live-run findings 2026-07-14)

Field test of the setup wizard surfaced three trust breaks in one
run; all were reproduced against a stale CLI and fixed:

- **Errors surfaced behind the wizard.** `chain init` failures were
  shown as a SnackBar, which lands BEHIND the wizard's modal barrier:
  dimmed, clipped, its copy button unreachable — and the operator's
  click at it hit the barrier, which (dismissible by default) closed
  the whole wizard with all answers. Now: failures open a modal error
  dialog ABOVE the wizard (copy button works, verbatim CLI output
  behind "Details"), and the wizard is no longer barrier-dismissible —
  leaving it is explicit via Abbrechen/Zurück.
- **CLI version skew explained.** When the resolved `chain` binary is
  older than Studio and rejects `--plan-json`, the wizard now names
  the skew in plain language — which binary was executed, that it
  predates the assistant, and the update path — instead of leaking a
  raw clap usage error. A missing binary gets the same treatment plus
  a hint on step 3 before anything runs.
- **macOS folder prompt pre-explained.** Step 3 now states which
  `chain` binary the preview will execute; when that binary physically
  lives (symlinks resolved) in a TCC-protected folder (Documents/
  Desktop/Downloads), the wizard says up front that macOS may ask for
  folder access — instead of a bare permission prompt appearing in
  the middle of setup.
- `FriendlyError` values now pass through `friendlyError()` unchanged
  so call sites can route precise, localized stories through the
  shared error presentation; `SystemActions` gained a public
  `resolvedChainBinary()` and test seams for the run/resolve paths.

### Added (guided setup on grade-1 — steps A4/A5/B1 + doc automation)

- **Clickable next steps.** After apply, the wizard renders real
  Studio actions instead of CLI text: start-hub button (polls until
  the daemon answers), per-module install buttons with progress/done
  states (capability-name install via the hub's store index), and an
  open-the-starter-flow button navigating to Flows.
- **Signature dead end resolved.** Regulated plans explain in plain
  language that modules come from a signed source; the preview offers
  "allow installing from the public store" as one deliberate,
  reversible switch (`allow_unsigned_modules`) that re-assembles the
  plan. Air-gapped plans point to the offline-bundle path instead.
- **Fresh-install auto-open + honest framing.** On a fresh hub (no
  config, no `setup-plan.yaml`) the wizard opens by itself, once per
  run; the welcome CTA is now "In 3 Fragen loslegen" / "Get started
  in 3 questions". After the wizard closes, the onboarding checklist
  re-probes and states what the assistant already covered (applied
  profile from `setup-plan.yaml`).
- **Free-text AI path (phase 1.2).** "Or just describe what you want
  to do": the goal goes to the configured system AI, the reply is
  validated against strict enum whitelists and comes back as an
  editable "this is how I read your task" reflection feeding the same
  preview/apply. Privacy line states local vs. provider processing;
  without a system AI the menu path stands alone.
- **Nav manifest guard.** `test/nav_manifest_test.dart` generates
  `docs/nav.generated.json` from the sidebar truth (ids, order = Cmd
  numbers, DE+EN labels); the platform repo checks the operator guide
  against the mirrored copy.
- **Guide screenshot harness.** `integration_test/guide_shots_test.dart`
  boots a hermetic hub, seeds demo projects, walks every nav page,
  the workspace switcher and the setup wizard, and writes the guide
  PNGs — driven by the platform repo's `scripts/regen-studio-guide.sh`.
- **Fixed:** the integration-test hub fixture still looked for the
  pre-rename `fai` binary and `chain_platform/` path, so its tests
  silently skipped since the rename; it now resolves `$CHAIN_BIN`,
  `chain` on PATH, and `../fai_chain/target/{release,debug}/chain`.

### Added (guided setup — persona re-audit fixes, grade-1 round)

- **Regulated path finishes without a terminal.** The post-apply
  signed-source state now offers "Add a signed source…" (the stores
  dialog with its pin-a-key field) plus the per-module install
  buttons, instead of a hint with no affordance; a plain-language
  trust hint explains why pinning the publisher's key matters.
- **Apply warnings surface.** Warning lines from `chain init --apply`
  (e.g. the empty-trusted-publishers caveat) are shown selectable in
  the done state instead of being swallowed on success.
- **Truthful preview.** New plan lines state which machine is being
  set up (server/container targets configure THIS machine — said
  explicitly), that regulated profiles get the hash-chained audit
  log even when WORM is off, and that a curated reading list is
  stored with the setup record.
- **Language pass.** Onboarding checklist switched to Sie-form and
  "System-KI" (was du-form + "System-AI" next to the formal wizard);
  "Audit-Sperre" jargon replaced with "Schreibschutz für das
  Prüfprotokoll"; answers file now lives in a private per-dialog
  temp dir instead of a fixed world-readable name.

### Added (multi-project, stage ③ — sealed areas)

- **Sealed-area connection switch.** 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.
- **Identity bar.** While connected to a sealed area, a strip 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. (The window-title
  tint is a small follow-up; the identity bar is the primary signal.)
- Selecting a shared project or "All projects" from inside a sealed area
  switches the connection back to the shared hub first. The sealed
  connection is never persisted across restarts — Studio always launches
  on the shared hub and the operator re-enters an area deliberately.

### Added (detached-runs monitor — T3 parity)

- **Runs page.** A new sidebar destination lists detached invocations
  (submitted with `detach: true`) with their phase, current step,
  project and a **Cancel** button while pending/running. Workspace-
  scoped like Audit and Approvals; polls every 2 s. Detached runs are
  opt-in (`detached.enabled`), so the empty state explains how to turn
  them on. Inline help doc (DE+EN). Backed by the SDK's
  `listInvocations()` + `cancelInvocation()`.

### Added (multi-project, stages ① + ②)

- **Workspace switcher.** The Audit and Approvals AppBars carry a
  workspace control listing the hub's project registry (colour dot per
  project, a shield for `protected`, an honesty tooltip). "All projects"
  stays reachable — a filter, not a jail. The selection is persisted and
  shared across pages; it re-scopes the audit list AND live stream
  hub-side, scopes approvals (pending + history), and drives the sidebar
  approval badge. Runs launched from the editor are stamped with the
  active workspace — unless the flow file declares its own `project:`,
  in which case the file wins (CLI semantics).
- **Editor project chip + file-wins guard.** A flow file's own
  `project:` shows as a chip; on mismatch with the active workspace an
  amber pill offers a one-click switch (the file still wins for the run).
  Backed by editor package 0.22.0.

### Fixed (usertest 2026-07-10 findings)

- **Approval prompts localize.** An approval whose flow step gave no
  `prompt:` (and legacy rows carrying the hub's old baked-in English
  sentence) now renders the localized fallback "Freigabe für diesen
  Schritt erforderlich" / "Approval required for this step" — no more
  English inside the German approvals UI.
- **Approving without review data asks first.** When the approval step
  attached no `show:` payload, "Freigeben" opens a calm confirmation
  ("Ohne Prüfdaten freigeben?") explaining that the flow deliberately
  attached no data, with an explicit "Trotzdem freigeben".
- **Studio error log moved to `~/.chain/logs/`.** Writes went to the
  pre-rename `~/.fai/logs/studio-errors.log` while the Doctor page and
  `chain doctor` read `~/.chain/…`. Studio now writes to `.chain` and
  migrates the old file (+ rotation sibling) over once.
- **Honest audit wording (legal review).** DE strings no longer claim
  "manipulationssicher" — the audit log is *manipulationserkennend*
  (tamper-evident); "warum WORM-1 für KRITIS reicht" became a neutral
  what-it-does-and-does-not sentence (EN too); the Doctor chain pill
  says "Integritätskette v1" instead of "WORM-1"; the federation
  enrollment hint says the CA *authenticates* the first connect.
- **WCAG-AA secondary text on dark.** De-emphasised text was 3.7:1 on
  cards; the muted token is now ≥ 4.5:1 against canvas, cards and
  elevated surfaces.

### Added

- **Live audit feed.** The Audit page subscribes to `streamEvents` and
  refreshes instantly on each new event (debounced); the 2 s poll stays
  as the safety net and re-subscribes after a clean stream close.
- **Channel switcher in the sidebar.** The active-channel pill (and the
  collapsed chip) is now click-to-switch: a menu of every channel with
  its running state + a check on the active one; switching writes
  `~/.chain/current-channel`, restarts that channel's daemon, and Studio
  repoints to it.
- **Module-store manager is prominent + bilingual.** The store page
  gains a labelled "Add store" button (was a bare icon) opening a fully
  localized dialog: configured stores, a curated **Suggested stores**
  shelf with one-click add/remove (probed for reachability — shows "not
  available yet" until a store's index is published), and an optional
  per-store **pinned public key** field.
- **Approval payload clarity.** The approval card always shows the
  payload section: a present payload scrolls inside a height-capped
  copyable box; an absent one explains that the flow's approval step
  chooses what to surface via its `show:` field.

### Fixed

- **Errors are copyable everywhere.** System-AI test-connection, the
  Settings dialog, and the Audit status bar rendered failures as
  non-copyable text; all now route through `ChainErrorBox` /
  `SelectableText`.
- **Filter dialog crash** on the store page — a `Spacer` inside
  `AlertDialog.actions` (an `OverflowBar`, not a Flex) threw; the
  buttons now sit in a `Row`.
- **Welcome docs grid** tidied into equal-height paired rows.
- **Approval card** leads with the human prompt; the `flow › step` id is
  demoted to a metadata line.
- **Pulsing sidebar connection dot** restored when connected.

## 0.70.0 — 2026-06-13

### Added

- **Federation panel.** A new "Föderation" destination shows the
  satellites connected to this hub (name, region, version, wire
  version, advertised capabilities) and adds them in one step: press
  **Add satellite**, name it, and the hub issues a single-use
  bootstrap token bundled with its CA as a ready-to-paste satellite
  config — the bundled CA makes the satellite's first connect
  tamper-proof. Localized (EN + DE) with an in-app help doc. Backed
  by new `HubClient.listSatellites` / `issueBootstrapToken` in the
  Dart SDK.

## 0.68.0 — 2026-06-09

### Added

- **Inline approval driver**. `StudioFlowRunDriver` implements
  the three new methods the editor 0.21.0 introduced
  (`pendingApprovalIdForStep`, `approveApproval`,
  `rejectApproval`) — all delegate to the existing
  `HubService` approvals RPCs. End result: the Run tab now
  hosts a complete Approve / Reject form inline, removing the
  tab-switch detour to the standalone Approvals page.

## 0.67.0 — 2026-06-09

### Added

- **Inline help icons** in the Approvals, Audit, and Doctor
  app-bars open the matching bundled doc in the existing
  bottom-sheet reader via the new public helper
  `showFaiDoc(BuildContext, slug)` exported from `welcome.dart`.
- **New `assets/docs/approvals.md`** (+ `_de.md`) explains the
  approval concept end-to-end with a YAML example.
- **friendlyError hub-pattern matching**. Six hub-specific
  failure shapes (approval rejected / timed out, output too
  large, host service not declared, missing value reference,
  MCP unreachable) get specific localised headlines + hints
  before falling through to the gRPC-code default. Five new
  test cases pin the matchers.

### Changed

- **Settings dialog sidebar fully localised** (Allgemein /
  Darstellung / System-KI / Integrationen / Sicherheit /
  Wartung). Per-panel titles + descriptions also.
- **Daemon action labels localised**: `enable autostart`,
  `disable autostart`, restart / start / stop / status + the
  OK / Failed result line.

## 0.66.0 — 2026-06-08

### Added

- **Add-module-source dialog** for private modules that
  aren't in the public store. Asks for URL or local `.fai`
  bundle path; carries an explainer block + `chain install --link`
  example.
- **Store catalogue** passed to the flow editor so the
  analyzer can decide between Install (in store) and Add
  source (not in store).

## 0.65.x

- Editor 0.18.0 pickup; analyzer-error block on Run;
  diagnostic strip persistence across tabs.

## 0.64.0 — 2026-06-08

### Added

- **Flow editor quick-fix install handler**.
  `_onInstallCapability` wires the editor's "Install <cap>"
  button to `HubService.installModule` and refreshes the
  capability list on success.

## 0.63.0 — 2026-06-04

### Changed

- **Settings dialog refactored** from one 800-line vertical
  scroll into a macOS-style sidebar with six categories.

## 0.62.x — 2026-06-03

### Added

- **`FaiLog` + central error helpers** (`showFaiErrorSnack`,
  `showFaiErrorDialog`).
- **Inline `FaiLogViewer`** modal for tail-viewing log files.
- **Today CTAs** in the Store carousel actually re-run search
  after a `filterCategory` / `runQuery` story.

## 0.61.x and earlier
