4-duplicated
Pins the stale / duplicated taxonomy edge → dedupe exact-edit kind →
derived auto tier (dedupe is non-destructive + reversible). The canonical_ref
points at the surviving copy, docs/setup.md.
Scanner signal exercised: stale_name_location (on docs/setup-legacy.md,
"legacy" in the name).
KNOWN GAP — surface for human review: the scanner has no dedicated
duplication signal; it cannot detect that setup-legacy.md is byte-for-byte
identical to setup.md. This case therefore rides a co-occurring
stale_name_location signal as the deterministic trigger, while the duplicated
classification itself is the model's judgment (the two files being identical). The
canonical docs/setup.md is present in input/ and correctly stays a cleared,
zero-signal shortlist entry. This is the one case where the intended subtype is not
backed by a matching scanner signal.
