 - Diagnostics: emit structured tool execution diagnostic events with trace context, timing, and redacted error metadata. Thanks @vincentkoc.
 - Diagnostics: emit structured run and model-call diagnostic events with trace context, duration, and non-message error metadata. Thanks @vincentkoc.
 - Control UI/chat: add a Steer action on queued messages so a browser follow-up can be injected into the active run without retyping it. Thanks @steipete.
+- Control UI/avatars: render authenticated assistant avatar routes through local blob URLs and allow those managed blobs in the dashboard CSP, restoring configured chat avatars. Fixes #71422. Thanks @blaspat.
 - Control UI/Talk: add browser WebRTC realtime voice sessions backed by OpenAI Realtime, with Gateway-minted ephemeral client secrets and `openclaw_agent_consult` handoff to the full OpenClaw agent. Thanks @steipete.
 - Plugin SDK/Codex harness: add provider-owned transport/auth/follow-up seams and harness result classification so Codex-style runtimes can participate in fallback policy without core special-casing. (#70772) Thanks @100yenadmin.
 - Codex harness: bridge Codex-native tool hooks into OpenClaw plugin hooks and approvals, with bounded relay payloads and approval spam protection. (#71008) Thanks @pashpashpash.

 ## Content Security Policy
 
-The Control UI ships with a tight `img-src` policy: only **same-origin** assets and `data:` URLs are allowed. Remote `http(s)` and protocol-relative image URLs are rejected by the browser and do not issue network fetches.
+The Control UI ships with a tight `img-src` policy: only **same-origin** assets, `data:` URLs, and locally generated `blob:` URLs are allowed. Remote `http(s)` and protocol-relative image URLs are rejected by the browser and do not issue network fetches.
 
 What this means in practice:
 
-- Avatars and images served under relative paths (for example `/avatars/<id>`) still render.
+- Avatars and images served under relative paths (for example `/avatars/<id>`) still render, including authenticated avatar routes that the UI fetches and converts into local `blob:` URLs.
 - Inline `data:image/...` URLs still render (useful for in-protocol payloads).
+- Local `blob:` URLs created by the Control UI still render.
 - Remote avatar URLs emitted by channel metadata are stripped at the Control UI's avatar helpers and replaced with the built-in logo/badge, so a compromised or malicious channel cannot force arbitrary remote image fetches from an operator browser.
 
 You do not need to change anything to get this behavior — it is always on and not configurable.
