=== Scanner decisions ===
Kuchle_c7 -> REUSED / REUSE_CUBIC_FANO_LINES
Kuchle_d3 -> REDUCED / CENTER_DIRECT_LEFSCHETZ_11
Kuchle_c5 -> NOVEL_ACTIVE_RESEARCH / NEW_BRIDGE_SEARCH

=== Dedup illustration ===
If 64 presentations collapsed to 3 source archetypes,
illustrative dedup ratio = 0.953125
NOTE: 3 is an archetype illustration, not a claimed exact quotient count.
