Struct ShadowProbe 

pub struct ShadowProbe { /* private fields */ }

A directory listing turned around: which of its files are conventionally named sidecars, and for what.

The lookup used to run the other way — build all six <payload>.<ext> candidates for a file and ask an ordered set of the listing whether it holds any of them. That is six PathBuf allocations and six ordered-set probes per file scanned, to answer “no” in every workspace with no attachments in it; over twenty thousand documents it was 16% of a check, most of it comparing paths component by component inside the set.

Inverting it costs one pass over the listing — the same <payload>.<ext> convention read backwards, so the two are exact inverses — and leaves the per-file question a single hash lookup that usually misses. A workspace with no attachments builds an empty map and every probe is that miss.

The content pointer is still what confirms a hit (Graph::sidecar_claims); this only says which files are worth asking about.
