RenderSegment

One provenance-tagged span of rendered output (Prompty Jinja Subset §7, spec/jinja-grammar.md). Concatenating every segment’s text in source order yields the flat string returned by render, so renderSegments is the provenance-carrying superset of render.

literal spans originate in the template source; interp spans originate in an interpolated input value and carry the originating root property source. That provenance lets a downstream structural parser distinguish an author-authored role boundary from one forged inside untrusted input — the injection-deterrence contract that replaces in-band sentinel scanning. A span whose source property is declared strict is flagged strict; a strict span that forges a role boundary is rejected loudly rather than emitted.
