@@ -21,6 +21,7 @@ Docs: https://docs.openclaw.ai
 - Plugins/runtime-deps: memoize packaged bundled runtime dist-mirror preparation after the first successful pass while keeping source-checkout mirrors refreshable, so constrained Docker/VPS installs avoid repeated root scans before chat turns. Refs #73428, #73421, #73532, and #73477. Thanks @Dimaoggg, @oromeis, @oadiazp, @jmfraga, @bstanbury, @antoniusfelix, and @jkobject.
 - Channels/Discord: treat bare numeric outbound targets that match the effective Discord DM allowlist as user DMs while preserving account-specific legacy `dm.allowFrom` precedence over inherited root `allowFrom`. (#74303) Thanks @Squirbie.
 - Control UI: make the chat sidebar split divider focusable, keyboard-resizable, ARIA-described, and pointer-event based so sidebar resizing works without a mouse. Thanks @BunsDev.
+- Agents/usage: keep PI embedded-run telemetry attributed to the resolved model provider instead of the PI harness label, so OpenRouter and other provider-backed turns report the right provider in session usage and traces. Thanks @vincentkoc.
 - Agents/auth: keep OAuth auth profiles inherited from the main agent read-through instead of copying refresh tokens into secondary agents, and refresh Codex app-server tokens against the owning store so multi-agent swarms avoid reused refresh-token failures. Fixes #74055. Thanks @ClarityInvest.
 - Channels/Telegram: honor `ALL_PROXY` / `all_proxy` and service-level `OPENCLAW_PROXY_URL` when constructing the HTTP/1-only Telegram Bot API transport, so Windows and service installs that rely on those proxy settings no longer fall back to direct egress. Fixes #74014; refs #74086. Thanks @SymbolStar.
 - Channels/Telegram: continue polling when `deleteWebhook` hits a transient network failure but `getWebhookInfo` confirms no webhook is configured, so startup does not retry cleanup forever after the webhook was already removed. Refs #74086; carries forward #47384. Thanks @clovericbot.
