 ### Added
 
+- **Settings → Extensions gallery cards now link back to their source and show permissions in readable groups.** Gallery and Installed cards now surface a safe "Source" link from registry metadata (falling back to the extension registry path when needed), and the permissions disclosure renders WebUI API access, storage, DOM, sidecar/native-host, filesystem, and external-network declarations as plain rows instead of raw JSON. Thanks @franksong2702. (#5093, #5095)
+
 - **Opt-in CSP `frame-src` allowlist so an extension can embed a self-hosted web app in an iframe.** A new `HERMES_WEBUI_CSP_FRAME_EXTRA` env var widens what the WebUI page may embed in an `<iframe>` (default is same-origin only), mirroring the existing `HERMES_WEBUI_CSP_CONNECT_EXTRA` knob — space-separated `http(s)` origins with optional wildcard subdomain and port, validated and ignored if malformed. This unblocks an "external app tab" extension (pin Grafana / Vaultwarden / your own dashboard as a tab). It only governs what *this* page can embed; `frame-ancestors` stays `'none'`, so it does not let anyone embed the WebUI itself. Default-off; with the var unset, behavior is unchanged. Documented in `docs/EXTENSIONS.md`.
 
 - **`/moa` now works in the WebUI, routing the turn through your configured Mixture-of-Agents preset.** Typing `/moa <prompt>` runs that turn through the agent's MoA config (the same preset/usage you'd get from the CLI) instead of a plain single-model turn; `/moa` with no prompt shows the available usage. The MoA config is resolved **server-side** from your profile config — the browser only signals that an override is wanted, it can't supply the config — and it's applied per-turn (not persisted). It fails closed on gateway-backed sessions. Thanks @rodboev. (#5070, #5057)
