Bug: Multi-agent footer shows no session metrics for non-default agents

[HarryLee1900]

Bug Report

Summary

In multi-agent OpenClaw deployments, the streaming card footer fails to display session metrics (token counts, model info, etc.) for all agents except the default (main). The footer renders as empty/blank for non-default agents.

Root Cause

In src/card/streaming-card-controller.ts, getFooterSessionMetrics() calls resolveStorePath() without passing an agentId parameter. The OpenClaw runtime's resolveStorePath defaults to "main" when no agentId is provided, so all agents resolve to main's sessions.json. Non-default agents (e.g. cook, margaret) find no matching entries there, resulting in blank footers.

The bug exists in both code paths:

1. sessionApi.resolveStorePath(sessionStorePath) — runtime in-memory store
2. channelSession.resolveStorePath(sessionStorePath) — filesystem fallback store

Reproduction

1. Deploy OpenClaw with ≥2 agents (e.g. main + cook)
2. Enable footer metrics in config: channels.feishu.footer.tokens: true (or context, model, etc.)
3. Send a message through a non-default agent (e.g. cook)
4. Observe: the completed card footer shows no metrics for the non-default agent
5. Send a message through main → footer displays correctly

Impact

• Only affects multi-agent deployments
• Single-agent setups work fine (the default "main" matches the only agent)
• Non-critical: footer metrics are informational, no functional breakage

Fix

The same resolveStorePath call in src/card/tool-use-config.ts already passes { agentId } (line 35):

const storePath = resolveStorePath(sessionStorePath, { agentId });

The fix aligns streaming-card-controller.ts with this existing pattern:

1. Extract agentId from the session key (agent:<id>:… format)
2. Pass { agentId: storeAgentId } to both resolveStorePath() calls
3. Update inline type declarations to include the opts parameter

PR

Fix available in #490

Environment

• openclaw-lark version: 2026.5.7
• OpenClaw version: 2026.5.x
• Agents: 10 (main, cook, margaret, zhangxiaolong, jobs, jonathan, wangyangming, jiamu, buffett, turing)
