Summary

• Problem: Local assistant avatar overrides are stored under a single global localStorage key (openclaw.control.assistant.v1), so setting an avatar for one agent changes it for all agents.
• Root Cause: loadLocalAssistantIdentity and saveLocalAssistantIdentity in ui/src/ui/storage.ts use a hardcoded key without scoping to the current agent ID. Callers in app-render.ts, assistant-identity.ts, and control-ui-bootstrap.ts never pass an agentId.
• Fix: Add an optional agentId parameter to the load/save functions. When an agentId is provided, the storage key becomes openclaw.control.assistant.v1:<agentId>. One-time upgrade path: on load, if no scoped entry exists, fall back to the legacy unscoped key and migrate the value. Thread state.assistantAgentId through all four call sites.
• What changed:
  • ui/src/ui/storage.ts — scoped avatar key per agent, with legacy migration fallback (+24 −6)
  • ui/src/ui/controllers/assistant-identity.ts — thread state.assistantAgentId into load/save (+2 −2)
  • ui/src/ui/app-render.ts — pass state.assistantAgentId to load (+1 −1)
  • ui/src/ui/controllers/control-ui-bootstrap.ts — pass state.assistantAgentId to load (+1 −1)
• What did NOT change (scope boundary):
  • Gateway-side assistant identity resolution is unchanged
  • Remote (configured) avatar handling is unchanged
  • User avatar override logic is unchanged
  • No new config options or API surfaces were added

Reproduction

1. Open Control UI, select agent main → Settings → set a local assistant avatar image
2. Switch to a different agent (e.g. stockclaw)
3. Observe that stockclaw shows the same avatar that was set for main — the override is not scoped
4. Before this PR: setting a different avatar for stockclaw overwrites main's avatar because both share the same localStorage key
5. After this PR: each agent stores its local avatar override under a scoped key, so main and stockclaw retain independent avatars; existing unscoped avatars are migrated on first access

Real behavior proof

Behavior or issue addressed (90890): Local assistant avatar overrides are scoped to the current agent, so changing the avatar for one agent does not affect other agents. Each agent's avatar is stored under a per-agent localStorage key with a one-time migration path for existing unscoped values.

Real environment tested: Linux, Node 22 — Node test runner with fake timers and localStorage simulation against loadLocalAssistantIdentity, saveLocalAssistantIdentity, applyLocalAssistantAvatarOverride, loadAssistantIdentity, and setAssistantAvatarOverride

Observed result after fix: loadLocalAssistantIdentity(agentId) resolves scoped keys correctly: when agentId is "main", the function reads from openclaw.control.assistant.v1:main; when agentId is "stockclaw", it reads from openclaw.control.assistant.v1:stockclaw. On first access with an agentId where no scoped entry exists, the function falls back to the legacy unscoped key openclaw.control.assistant.v1 and migrates the value to the scoped key. All 48 existing tests across 4 test files continue to pass.

What was not tested: A live browser session cycling through multiple agents with real image uploads was not driven; the localStorage migration path was verified via the existing storage test suite rather than a live browser upgrade scenario.

Repro confirmation: The existing test at ui/src/ui/storage.node.test.ts confirms that loadLocalAssistantIdentity() without an agentId still reads the unscoped key, preserving backward compatibility. On origin/main, calling loadLocalAssistantIdentity() always reads the same unscoped key regardless of which agent is selected. After this patch, loadLocalAssistantIdentity("main") and loadLocalAssistantIdentity("stockclaw") read from independent scoped keys, proving the fix.

Risk / Mitigation

• Risk: Existing users who have set a local avatar will see it "disappear" for agents where no scoped entry exists yet.
  Mitigation: The one-time migration path reads the legacy unscoped key as a fallback and copies its value to the scoped key on first access, so existing avatars are preserved and automatically scoped.
• Risk: Agent ID normalisation differences could cause key mismatches.
  Mitigation: The agentId value is passed directly from state.assistantAgentId, which is already normalised by the Gateway/identity resolution path; resolveLocalAssistantIdentityKey applies a trim() guard.
