-# Agent Observability Update
-
-Date: 2026-03-10
-
-This session improved agent observability without altering crash semantics or restart behavior.
-
----
-
-## Structured Logging
-
-Operational logs now use component tags:
-
-- `[process]`
-- `[http]`
-- `[files]`
-- `[console]`
-- `[state]`
-
-Each log entry includes the VMID when available.
-
----
-
-## Crash Metadata
-
-The agent now records and exposes via `/status`:
-
-- `lastCrashTime`
-- `lastCrashExitCode`
-- `lastCrashSignal`
-- `lastCrashUptimeSeconds`
-- `lastCrashLogTail`
-
----
-
-## Readiness Timeout
-
-A constant was introduced:
-
-```go
-const ReadinessTimeout = 60 * time.Second
-```
-
-This centralizes the readiness policy and allows tuning without searching for hardcoded values.
-
----
-
-## Crash Semantics
-
-Crash classification unchanged:
-
-```
-unexpected exit  →  crashed
-intentional stop →  idle
-readiness failure → error
-```
-
-This ensures crash metrics remain accurate and are not inflated by intentional operations.
