@@ -17,6 +17,7 @@ Docs: https://docs.openclaw.ai
 - Docs/Mermaid: remove hardcoded Mermaid init theme blocks from four docs diagrams so dark mode inherits readable theme defaults. (#15157) Thanks @heytulsiprasad.
 - Outbound/Threading: pass `replyTo` and `threadId` from `message send` tool actions through the core outbound send path to channel adapters, preserving thread/reply routing. (#14948) Thanks @mcaxtr.
 - Sessions/Agents: pass `agentId` when resolving existing transcript paths in reply runs so non-default agents and heartbeat/chat handlers no longer fail with `Session file path must be within sessions directory`. (#15141) Thanks @Goldenmonstew.
+- Status/Sessions: stop clamping derived `totalTokens` to context-window size, keep prompt-token snapshots wired through session accounting, and surface context usage as unknown when fresh snapshot data is missing to avoid false 100% reports. (#15114) Thanks @echoVic.
