reconcile() compares one accepted identity with its tag and the catalog entry and
publishes a state plus the individual signals (JAN exact, name by longest common
substring, price against either the sale or the regular price). It never changes
the product identity: a disagreement is a second opinion shown next to the first,
and only a checksummed barcode outranks the matcher.
evaluate_compliance() is the first rule family: missing_price_tag, the owner's
missing_tag_group (>= 3 consecutive facings without a tag), orphan_tag,
price_mismatch, plus an unreadable_tags hint. Every rule fails closed on evidence
quality - a row whose tags could not be read produces "move closer", never a
violation. Findings must appear in 3 of the last 5 frames before they publish, so
the UI never flickers.
