# 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.
