Summary

Tells the model once per session when the Gortex daemon is down, matching Claude Code. The notice comes from Gortex as a tool_call decision's additional_context (zzet/gortex#1284), which the extension already appends to that call's result, so no source change is needed here.

During an outage the graph call itself fails, so this adds a suite case pinning that guidance also joins a failed call's result. Pi runs tool_result handlers for failed tools too.

Depends on zzet/gortex#1284. Against a Gortex without it, a call during an outage gets an empty decision and the model hears nothing, as today. Merge after a Gortex release ships #1284.

Closes #49

Testing

• npm run check passes
• New behaviour has a suite that drives it through Pi's ExtensionRunner (see docs/tests.md)
• Tried by hand in Pi (pi -e /path/to/checkout), if user-visible

Also verified outside the harness: a real Pi AgentSession with a scripted model, the extension spawning a locally built Gortex with #1284. After the hook was pointed at a dead daemon socket mid-session, the first indexed read's result carried the notice and the second carried nothing. With released Gortex both results carried nothing.

Checklist

• No runtime dependencies added
• README configuration table updated, if config changed
• docs/architecture.md updated briefly, only if a design decision changed
• Works on Windows paths and process spawning, if touching either
