citationMarkerPattern top-level constant

String const citationMarkerPattern

Canonical [n] citation marker pattern (§1 of the citations spec) — the single source of truth for both CitationSyntax's markdown match and any plain-text existence check (e.g. "does this turn's text contain a citation?", used to decide whether to schedule a grounding refetch).

Implementation

const String citationMarkerPattern = r'\[(\d+)\]';
