# Changelog

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

## Unreleased

### 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
