Struct StallReport 

pub struct StallReport {
    pub pid: pid_t,
    pub comm: String,
    pub samples: Vec<SchedSample>,
    pub captured_at: Instant,
    pub diagnostic: StallDiagnostic,
}

One stall report: a worker pid plus the sample window that triggered the stall predicate plus the captured diagnostic.

Pushed onto StallMonitor::reports by the polling thread the moment the predicate fires. The thread continues running so subsequent stalls on the same pid (or other pids) also surface, but a pid is “re-armed” only after observing forward progress (any non-zero delta) so a permanently-stuck task fires once and then stays silent until it moves again — preventing a single stall from spamming the report list every poll cycle.

Fields

pid: pid_t

The stalled worker’s pid.

comm: String

comm field from /proc/<pid>/comm at trip time — the task’s name (SpinWait_0, etc.) so an operator can map the pid back to a scenario WorkSpec without inspecting the diagnostic’s full status file.

samples: Vec<SchedSample>

The sample window that triggered the predicate. Length equals STALL_WINDOW at the moment of fire; later samples are NOT appended (each report is a snapshot, not a rolling view).

captured_at: Instant

Wall-clock instant the predicate fired. Not serialized — see SchedSample::captured_at for the rationale.

diagnostic: StallDiagnostic

Diagnostic snapshot captured immediately after the trip.
