Struct GovernorManifest 

pub struct GovernorManifest {
    pub terminable: Option<bool>,
    pub min_idle_secs: Option<u64>,
    pub memory_budget_kb: Option<u64>,
}

Idle-termination policy for a lazily-started app (issue #811 SP1 — the app governor). Nested under AppManifest::governor.

Fields

terminable: Option<bool>

Explicit opt-out. Some(false) exempts the app from idle termination regardless of any other eligibility rule. None/Some(true) defers to the other eligibility rules.

min_idle_secs: Option<u64>

Minimum idle duration, in seconds, before the governor may terminate this app — overrides the governor’s default sweep threshold. None defers to the default.

memory_budget_kb: Option<u64>

Memory budget in KB. When the app’s measured footprint — on the basis selected by its measurement attribution, see node_app_host::app_memory::budget — exceeds this, the owner is warned in the shell.

What None defers to

NOT one number. The default is chosen PER BASIS (node_app_host::app_memory::budget::default_budget_kb), because the bases are not comparable quantities:

basis	default	why
heap_used, pss	10,240 KB	the app and nothing else
rss	61,440 KB	the whole OS process, runtime included
not_attributable	10,240 KB	never over; carried only for the wire

A shared-runtime Bun worker is compared on heap_used; a dedicated process or cgroup-scoped standalone on rss, which charges it for a JavaScript engine it did not choose and cannot shed.

On top of that, a host-side runtime-critical entry (RUNTIME_CRITICAL_BUDGETS) acts as a FLOOR, never a ceiling: it can only raise an app above the per-basis default, never pull it below one.

A value declared HERE is the one thing that overrides both, in either direction — it is a deliberate choice by the app author, not a fallback, so it is honoured unchanged even when it is lower than the default.

Apps that legitimately need more than their basis default MUST declare a realistic budget here; otherwise the warning is permanently lit and stops meaning anything.
