Struct WalEvent 

pub struct WalEvent {

    pub seq: u64,
    pub ts: u64,
    pub event_type: WalEventType,
    pub job_id: String,
    pub capability: Option<String>,
    pub output: Option<Value>,
    pub error: Option<String>,
    pub telemetry_before: Option<Telemetry>,
    pub telemetry_after: Option<Telemetry>,
    pub process_before: Option<ProcessSummary>,
    pub process_after: Option<ProcessSummary>,
    pub cmd: Option<String>,
    pub cmd_stdout: Option<String>,
    pub cmd_stderr: Option<String>,
    pub cmd_exit_code: Option<i32>,
    pub cmd_corrected: Option<String>,
}

A single WAL event record.

Events are appended sequentially and identified by seq. The ts field is a Unix timestamp in seconds. Optional fields (capability, output, error, cmd_*) are skipped during serialization when None.

Command Execution Events

When event_type is WalEventType::CommandExecuted, the cmd* fields capture the shell command, its output, and any auto-correction applied. These events are only written in debug builds (#[cfg(debug_assertions)]), but the variant exists in release builds for reading old WALs.

Fields

seq: u64

Sequence number (monotonically increasing within a writer session).

ts: u64

Unix timestamp (seconds) when the event occurred.

event_type: WalEventType

Type of the event (job lifecycle stage or command execution).

job_id: String

The job ID this event relates to.

capability: Option<String>

Capability name, if applicable.

output: Option<Value>

Output data from the capability, if applicable.

error: Option<String>

Error message, if the event represents a failure.

telemetry_before: Option<Telemetry>

Hardware telemetry snapshot before execution.

telemetry_after: Option<Telemetry>

Hardware telemetry snapshot after execution.

process_before: Option<ProcessSummary>

Process summary before execution.

process_after: Option<ProcessSummary>

Process summary after execution.

cmd: Option<String>

Shell command string (CommandExecuted events only).

cmd_stdout: Option<String>

Captured stdout, truncated to 1KB (CommandExecuted events only).

cmd_stderr: Option<String>

Captured stderr, truncated to 1KB (CommandExecuted events only).

cmd_exit_code: Option<i32>

Exit code of the command (CommandExecuted events only).

cmd_corrected: Option<String>

Auto-corrected command, if correction was applied (future Phase 2).
