When using multiple agents with different workspaces (e.g., main and family agents), sessions fail with error:
Error: Session file path must be within sessions directory
Root Cause:

The resolveSessionFilePath() function in several modules doesn't receive the agentId parameter, causing it to default to the main agent's sessions directory. When a session belongs to a different agent (e.g., family), the absolute path validation fails.

This appears to be a regression introduced by the security hardening in v2026.2.12 (transcript path resolution improvements).

Affected Files:

• loader-DsT_r87T.js (lines ~36546, ~42080)
• extensionAPI.js (lines ~20051-20053, ~20145, ~20683, ~23716, ~23046-23047, ~23117, ~24027, ~38423)
• pi-embedded-DY_lx0y_.js (similar locations)
• reply-SjB6cawm.js (similar locations)
Steps to Reproduce:

1. Configure multiple agents in openclaw.json:
   {
   "agents": {
   "list": [
   { "id": "main", "workspace": "/data/workspace" },
   { "id": "family", "workspace": "/data/workspace-family" }
   ]
   },
   "bindings": [
   {
   "agentId": "family",
   "match": {
   "channel": "telegram",
   "peer": { "kind": "group", "id": "-123456789" }
   }
   }
   ]
   }
2. Send a message to the bound group chat
3. Error occurs in Telegram handler
   Expected Behavior:
   Session files should resolve to the correct agent's sessions directory.

Actual Behavior:
Error: Session file path must be within sessions directory

Workaround Applied:

Modified calls to resolveSessionFilePath() to pass { agentId } or { agentId: params.agentId }:

Example:
// Before
const sessionFile = resolveSessionFilePath(sessionIdFinal, sessionEntry);

// After
const sessionFile = resolveSessionFilePath(sessionIdFinal, sessionEntry, { agentId });
Also updated readUsageFromSessionLog() signature to accept and pass agentId.

Environment:

• OpenClaw version: 2026.2.12
• OS: Debian 12 (Railway container)
• Node: v22.22.0
Additional Context:
This affects all multi-agent setups where agents have different workspaces and sessions are bound to specific agents via bindings.
