 ### Fixes
 
+- Agents/session usage tracking: preserve accumulated usage metadata on embedded Pi runner error exits so failed turns still update session `totalTokens` from real usage instead of stale prior values. (#34275) thanks @RealKai42.
 - Nodes/system.run approval hardening: use explicit argv-mutation signaling when regenerating prepared `rawCommand`, and cover the `system.run.prepare -> system.run` handoff so direct PATH-based `nodes.run` commands no longer fail with `rawCommand does not match command`. (#33137) thanks @Sid-Qin.
 - Models/custom provider headers: propagate `models.providers.<name>.headers` across inline, fallback, and registry-found model resolution so header-authenticated proxies consistently receive configured request headers. (#27490) thanks @Sid-Qin.
 - Ollama/custom provider headers: forward resolved model headers into native Ollama stream requests so header-authenticated Ollama proxies receive configured request headers. (#24337) thanks @echoVic.
