Struct StartupContext 

pub struct StartupContext {
    pub atlas: String,
    pub atlas_budget_used: usize,
    pub skeleton: String,
    pub surface: String,
    pub important: String,
    pub surface_render: SurfaceRenderResult,
    pub coverage: Vec<String>,
    pub omissions: Vec<String>,
    pub artifact: ContextArtifact,
}

The startup artifact: atlas + surface + coverage + omissions, with the deterministic artifact hash. surface_render is the SAME render the artifact printed — ledger recording derives visible ids from it, so the surface is never computed twice per startup.

Fields

atlas: String

atlas_budget_used: usize

Atlas budget the DELIVERED atlas text was rendered under (normally the loop’s final atlas_budget, or the 256-token essentials budget on the emergency floor). The ledger rebuilds the same pack, so recorded atlas ids never describe undelivered text (§53 coupling).

skeleton: String

Deterministic physical-layout evidence (repository skeleton), built from the indexed file inventory under its own hard budget.

surface: String

important: String

IMPORTANT SYMBOLS section (audit item 3): the fast “where do I pay attention first” answer, rendered before the long Surface Map detail. Computed from the same global rank the surface used.

surface_render: SurfaceRenderResult

coverage: Vec<String>

omissions: Vec<String>

artifact: ContextArtifact
