The matcher stops trusting what the user can't see

Browse Source 
Eric's question cut to the bone: "How would a user know? It matched
wiz-war and that IS the game." The auto looked unanimous because the
matcher discarded the evidence of doubt before anyone saw it — and
worse, BGG's search hides evidence of its own: results truncate
unordered in the several-hundreds (the game named "Dungeon!" appears
in NEITHER the "Dungeon!" nor the "Dungeon" search), and punctuation
can bury matches.

Three matcher changes: every title is searched raw AND depuncted,
merged by id; a name that becomes exact once its trailing
parenthetical is stripped ("Wiz-War (Eighth Edition)") is a sibling
edition — BGG files new editions as separate games — and enters the
candidate set at exact grade, so same-named lineages land in review as
a visible choice; and a LONE candidate must now earn trust (stats
fetched, sibling-grade never autos alone, true exacts must clear the
dominance ownership floor) — closing the fast path both impostors
(.dungeon at 31 owners, then Dungeon (ICP)) walked through.

Recorded outcomes: WIZ-WAR → ambiguous with all three lineages on the
ballot; Dungeon! → ambiguous (its true match is beyond BGG's search
horizon — that's what manual id is for); every legitimate auto in the
fixture set held. And the answer to Eric's second question is now
structural: re-match never re-decides — it demotes to unmatched and
the HUMAN picks from re-search or manual id; the machine only chooses
on first resolve, and it now chooses more humbly.

<name type="primary" sortindex="1" value="Flat Top" />
<description>Flat Top is a board wargame of high complexity that covers the battles of the Solomon Seas between the United States and Japan in 1942. It is very well researched and covers all aspects of naval and air combat as it existed in 1942. The system depicts weather, air searches, air combat, surface combat, carrier operations, submarines, air bases, supplies, and much more. The game requires intense planning and searching since movement is covert and the map is huge.
The units are individual ships and submarines with each air point representing three aircraft. Hexes are twenty miles, and each turn represents one hour.
The game includes thirteen hundred counters, 4 maps to create a 44" x 28" map of the South Pacific, four Allied/Japanese operations cards, three player aid cards and two log sheets.
First edition Battle Line has two counter card sheets containing 800 counters.
