Struct RuleContext 

pub struct RuleContext {
    pub marking_type: MarkingType,
    pub zone: Option<Zone>,
    pub position: Option<DocumentPosition>,
    pub page_context: Option<Arc<PageContext>>,
    pub corrections: Option<Arc<HashMap<String, String>>>,
}

Document position context passed to rules alongside parsed markings.

Phase 3 made zone and position Option-typed: the scanner cannot reliably determine header/footer/body or document position from raw text alone, so a rule that reads either field must handle None. They will become populated in a future scanner pass that consumes document structural metadata (page count, line numbers, header/footer detection on extracted documents).

page_context is populated by the engine for every non-portion candidate (Banner, CAB) so banner-validation rules can compare the observed banner against the composite expected from all preceding portions. The engine resets it at scanner-emitted MarkingType::PageBreak candidates (form-feed \f and \n\n\n+ heuristics) so the context reflects only the current page.

Fields

marking_type: MarkingType

zone: Option<Zone>

Document zone (header/footer/body/CAB) when known. None in Phase 3 — the scanner cannot prove header vs footer from raw text.

position: Option<DocumentPosition>

Coarse document position when known. None in Phase 3.

page_context: Option<Arc<PageContext>>

Accumulated portion data for the current page, reset at every scanner-emitted MarkingType::PageBreak.

corrections: Option<Arc<HashMap<String, String>>>

Organization-specific corrections map from config [corrections]. None when no corrections are configured.
