-## 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.

-# Federation
-
-Federation lets one hub (the **primary**) run capabilities on
-another hub (a **satellite**) — for example to reach a GPU box or to
-keep data inside a specific location. A flow step opts in with an
-`on:` selector; everything else stays exactly like a local step.
-
-This panel is the **primary** side: it shows the satellites currently
-connected and lets you enrol new ones.
-
-## Add a satellite
-
-1. Press **Add satellite** and give it a name (e.g. `satellite-a`).
-2. The hub issues a single-use **bootstrap token** and bundles its
-   **CA certificate**. Copy the shown config into the satellite's
-   `config.yaml` (one paste) and export the token as
-   `FAI_BOOTSTRAP_TOKEN`.
-3. Start the satellite. It dials the primary, the CA pin makes the
-   first connect tamper-proof, and the primary signs it a short-lived
-   certificate. It then appears in this list.
-
-## How it stays secure
-
-- The satellite **dials outbound** — no inbound firewall change.
-- Every connection is **mTLS**. The first connect is verified against
-  the bundled CA; later connects authenticate with the satellite's
-  own certificate (no token needed).
-- The satellite resolves and runs the capability in **its own
-  sandbox** — only inputs cross the wire, never code.
-- Each cross-hub call is recorded on both sides (`dispatched_to`), so
-  the audit trail and replay determinism survive federation.
-
-## Using a satellite in a flow
-
-Add an `on:` selector to a step:
-
-```yaml
-- id: extract
-  use: text.extract@^1
-  on: region=berlin        # or pin=satellite-a, auto:healthiest, auto:lowest_rtt
-  with:
-    input: $inputs.doc
-```

-# Föderation
-
-Föderation lässt einen Hub (den **Primary**) Capabilities auf einem
-anderen Hub (einem **Satelliten**) ausführen — etwa um eine GPU-Maschine
-zu erreichen oder Daten an einem bestimmten Ort zu halten. Ein
-Flow-Schritt entscheidet sich per `on:`-Selektor dafür; alles andere
-bleibt wie bei einem lokalen Schritt.
-
-Dieses Panel ist die **Primary**-Seite: Es zeigt die aktuell
-verbundenen Satelliten und richtet neue ein.
-
-## Satellit hinzufügen
-
-1. **Satellit hinzufügen** drücken und einen Namen vergeben
-   (z.B. `satellite-a`).
-2. Der Hub stellt ein einmaliges **Bootstrap-Token** aus und legt sein
-   **CA-Zertifikat** bei. Kopiere die gezeigte Konfiguration in die
-   `config.yaml` des Satelliten (ein Einfügen) und exportiere das
-   Token als `FAI_BOOTSTRAP_TOKEN`.
-3. Starte den Satelliten. Er wählt sich beim Primary ein, der CA-Pin
-   macht den ersten Connect manipulationssicher, und der Primary
-   signiert ihm ein kurzlebiges Zertifikat. Danach erscheint er in
-   dieser Liste.
-
-## Warum es sicher bleibt
-
-- Der Satellit **wählt sich nach außen ein** — keine eingehende
-  Firewall-Änderung nötig.
-- Jede Verbindung ist **mTLS**. Der erste Connect wird gegen die
-  beigelegte CA verifiziert; spätere Connects authentifizieren sich
-  mit dem eigenen Zertifikat des Satelliten (kein Token nötig).
-- Der Satellit löst auf und führt die Capability in **seiner eigenen
-  Sandbox** aus — nur Eingaben gehen über die Leitung, niemals Code.
-- Jeder hub-übergreifende Aufruf wird auf beiden Seiten protokolliert
-  (`dispatched_to`), sodass Audit-Trail und Replay-Determinismus die
-  Föderation überstehen.
-
-## Satellit in einem Flow nutzen
-
-Ergänze einen `on:`-Selektor an einem Schritt:
-
-```yaml
-- id: extract
-  use: text.extract@^1
-  on: region=berlin        # oder pin=satellite-a, auto:healthiest, auto:lowest_rtt
-  with:
-    input: $inputs.doc
