Enum MetaMode 

pub enum MetaMode {
    StreamingPartial,
    SmallFileSingle,
}

Which RTC-detection ladder resolve_stream_meta should run.

Variants

StreamingPartial

Streaming early-meta: the caller’s decoder sees only a PARTIAL entity index (the file head scanned so far), so RTC detection runs the 3-stage fallback ladder — partial-index detect → full-index re-detect (triggered when no large offset was found AND either the IfcSite has not been scanned yet OR the partial index resolved no usable placement chain) → placement-bounds last resort — instead of silently defaulting to no-shift and rendering f32 vertex jitter on models whose world offset lives in late spatial placements.

SmallFileSingle

The caller’s decoder already sees the FULL entity index (the small-file streaming tail, or the single-pass buildPrePassOnce), so a single GeometryRouter::detect_rtc_offset_with_fallback is correct.
